The kitten met Shang Tao Yinzhen's worried and forbearing red eyes, took a step closer and hugged her, "I went to the research institute, and it will be so late in the future, don't worry."

The research institute is a place where only outstanding talents in various fields can enter after being approved by the empress.

Tao Yinzhen had mixed feelings, admiring the empress's tolerance and generosity, and regretting that she was obsessed with ghosts for a while.

She put on a smile, "Well, mother knows, the food is still in the pot, let's eat."

"it is good."

The kitten is still eating very fast, and can't wait to draw the design concept of the automatic lamp.

Tao Yinzhen suddenly stopped him, "Little cat, the Zhang family is still waiting for an answer. If you don't want to, I'll refuse this marriage on the pretext that you are still young."

The kitten paused and looked at her, "Mom, promise."

Tao Yinzhen thought that he would not agree. After all, the two children seemed to have conflicts before, and the kitten agreed. She was surprised for a moment, and said happily: "Okay, okay, okay."

The kitten returned to the room and lit a candle. On the basis of the electric light, a kitten doll was designed, intending to insert a small power generation device into the doll, and design the kitten's eyes as lights.

After school the next day, he rushed to the scientific research room, trying to turn the generator that was assembled yesterday into a lighting lamp.

But he soon discovered that it is very easy to heat up the generator just put in the doll, and the wick is very inconvenient to contact, so it cannot be easily and conveniently made to light up immediately.

When he was still studying how to solve this problem, the wick suddenly went out. He checked and checked and consulted other people, only to realize that the generator he made was too small and the power supply was insufficient, so the wick could only be on for a while.

There are only two ways to make the doll brighter longer, replace a large generator, and then continue to supply power, or try to find a way to continuously transmit current into the generator inside the doll.

If you change to a big generator, the whole doll will be very bulky.

What if you feed electricity into a generator inside the doll? What about the connections?

The little cat was at a loss, so he asked all the people in the scientific research room one by one, and He Jinchuan, who was in charge of repairing the power station, told him: "As long as the line is long enough, just plug it in directly."

The kitten didn't know about the power station yet, so he couldn't help asking, "If there are no sockets around, can't we find a way to store electricity in the doll, or make it easy to carry?"

It will take at least half a year until the power station is fully built to fully supply electricity to the entire Xiaoyao City.

The kitten now wants to find a way to turn on the light without plugging in the wires.

He Jinchuan was dumbfounded by the kitten's question, and it took him a long time before he said: "You can think about it for yourself." Afraid that he would run to ask Bai Wutong, he told him: "The empress is about to give birth, so don't bother her with trivial matters."

The kitten nodded, "I won't bother the empress, I'll figure it out myself."

He Jinchuan chuckled, "A newborn calf is not afraid of tigers." He threw a book at random, "Take it and read it carefully, maybe you will find the answer."

The kitten took He Jinchuan's book, and it turned out to be a complex advanced edition of mathematics, physics and chemistry.

He thanked He Jinchuan ecstatically, and He Jinchuan said with a smile: "Ask me if you don't understand, although I don't understand some of them."

The kitten bowed deeply again, and said gratefully: "Thank you."

"You're welcome. I'd also like to know how the light can be turned on without the wire device."

One big one and one small one looked at each other and smiled, and went back to their respective researches.

The kitten has to go to school during the day, and then goes to the research institute after school. Sometimes, he will stay up all night in the research institute. His energy is low, so he dozes off in class.

But Kitten's grades are also the best, so it is inevitable that some people think that he is arrogant with his talents, and he doesn't pay attention to the teacher and others, and talks about him behind his back.

The bishop teacher of the kitten is good friends with Cui Shize, so he went to find Cui Shize and told him the recent situation of the kitten, so as to prevent the kitten from being isolated by everyone.

No matter how talented a person is, it is hard to escape the criticism of this world. Teacher Bishop still hopes that the kitten will not be so independent.

Cui Shize knew Xiaomao well and knew that he was definitely not arrogant and arrogant. Thanks to the teacher Bishop for reminding him, he found Xiaomao and asked him about his situation.

Knowing that the kitten has been staying up all night doing research, and that the middle school curriculum is too easy, he is so tired that he dozes off.

But since the kitten knew about everyone's discussion, he would drink a large cup of strong tea every day after class to drive away sleepiness and feel very distressed.

Cui Shize thought about it for a while and said, "If you make an answer sheet and meet the requirements, you can enter Qinghe University in advance."

Since the kitten is smart, there is no need to waste his talent in middle school.

The courses of Qinghe University are chosen independently, and the time can also be adjusted according to personal circumstances. The courses are not as intensive as those of middle schools.

The kitten's eyes lit up, and he nodded quickly, "Thank you, Teacher."

In this way, he can have more time to solve the way of storing electricity.

Cui Shize quickly arranged for the kitten to be admitted to Qinghe University.

In Qinghe University's entrance examination, in addition to the basic examination, there are many professional classifications. According to the examination requirements of one plus three, the kitten completed it in one go, and took the examination for two hours in the examination room set up separately for him.

As soon as the examination papers were received, academicians such as Yang Quanzi personally corrected the basic examination papers, and the other three professional examination papers were also reviewed by professional teachers.

In an hour's time, the kitten's results came out.

Except for open-ended answers, the kitten has almost perfect marks.

With such an excellent answer sheet, Cui Shize can guarantee that the gentlemen of Qinghe University may not be able to fully achieve it.

He entered Qinghe University smoothly, and besides the scientific research room, he asked all kinds of questions to the gentlemen of mathematics, physics and chemistry.

Although they are gentlemen, their real contact with mathematics, physics and chemistry has not been longer than the kitten, but they have listened to Bai Wutong's lectures at close range.

Soon, they couldn't keep up with the rhythm of the kitten, and they were even a little afraid that the kitten would keep coming to them.

The little cat spread the news that the teachers of Qinghe University were afraid of him, and the rumors about him were wiped out, and he became an existence that many students looked up to and admired.

Mrs. Zhang also felt that ordering a kitten for her daughter in advance was a treasure.

At this moment, the kitten did another earth-shattering event.

He kept researching and finally found a way to store electricity alone.

After Bai Wutong heard the news, he immediately came to the scientific research room.

I saw a doll placed in front of the kitten. The eyes of the doll were always lit with two wicks.

Everyone said: "Isn't this just putting a generator in your stomach?"

He Jinchuan shook his head with a smile, "This doll has been lit since yesterday, and the power should have been exhausted long ago. There is a lot of space inside."

Bai Wutong's due date is at the end of this month. Everyone carefully avoided an area and carried a comfortable chair for Bai Wutong.

Bai Wutong looked at the kitten and said gently, "I heard that you can transmit electricity into the doll, so I'll take a look."

Bai Wutong could have summoned him, but he came in person. The kitten quickly introduced: "Well, I installed a device similar to a generator in the doll. This device can generate electricity, and it can also power other generators. When the doll has no electricity, use the loop structure in the device to connect with other generators, and then the electricity can be transmitted."

A scientific researcher said: "Then you need multiple generators to supplement the power, and it is very troublesome to be different."

He Jinchuan shook his head, "When the power plant is fully established, there will be no need to use a small generator. Connect the line to the kitten's loop interface, and you can use electricity directly, light up the lights, and use it in places where you can't plug in the line. Such a portable light will be very convenient, this is a great creation."

He Jinchuan's explanation made everyone's eyes brighten. Indeed, if the electricity can be used portablely, then even if they are far away, the machines they created that need to be supplied with electricity can be used in the same way.

Especially Zhao Yuan, his eyes seemed to shoot out laser light, he didn't expect the kitten to really do it.

He excitedly said: "Can you show me the internal structure?"

He has also been trying to combine a generator with a bicycle, but the energy required is too great, and there is no way to run at a high frequency without connecting wires. The invention of the kitten is like a timely rain.

Others also looked eager for knowledge. If they can make use of this technology, it will definitely make Happy City reach an incomparable peak.

Affirmed by He Jinchuan, the little cat had a smile on his face. He opened the doll's belly, took out the power storage device from inside, let everyone watch the internal working structure closely, and explained in detail where he got it. inspiration.

Bai Wutong thought that the power storage device mentioned by the kitten was like a lithium battery, but what is amazing is that it is not the same as the principle structure of a lithium battery, but a structure similar to the energy change caused by the end of the world, which was peeped by the kitten from the book Transparent, directly skipping the era of lithium electronics that will cause pollution in the middle, and entering the era of environmentally friendly energy.

It has to be said that some people are born geniuses in this area.

Bai Wutong only used the space to impart some knowledge, and he was able to draw inferences from one instance and reach the peak of the era.

Bai Wutong said with emotion: "The wireless storage electrical device can free the machine from the restriction of the wire, and you can hold the sun when you travel at night. Kitten, you have created a new era."

The kitten said modestly: "Although the power storage device is convenient, the power is still not as high as wired transmission. If you need to use high-power lights, you still have to rely on wired devices."

Modern large-scale mechanical vehicles mostly rely on oil to run, electric vehicles require special conversion equipment, and solar-powered suspension vehicles require solar light-velocity panels. Baiwutong has detailed manufacturing steps, processes, drawings, and videos, but it can’t make you fat if you eat it all at once. , I will reveal a little bit in due course in the future, let them continue to explore first, and then go to overcome these technologies.

Bai Wutong smiled and said: "There is no need to be humble, you have made great contributions to our Xiaoyao Country."

The little cat rarely showed a hint of embarrassment, "I just want the empress to use a more convenient fan, but I haven't made it yet."

Bai Wutong smiled and said: "It will be done soon, are you willing to become a senior backbone researcher of the institute?"

The kitten raised its head abruptly, "Can I?"

Bai Wutong looked around, "Your talent is obvious to all. If you can't join the institute, it will probably be our loss."

Research fellows at the Institute have several ratings.

There are only a few senior backbone researchers now, who enjoy national treasure treatment and special escorts for travel protection.

The kitten is less than ten years old, and he can stand shoulder to shoulder with several other researchers. Envy flashed across the faces of the other researchers, but they had to admit that the kitten is very talented. Perhaps they would not be able to achieve what he is today in their entire lives. .

There are people and things that Kitty likes in the research institute, and if he can get the title of senior backbone researcher, he can freely enter the library and various research rooms of the research institute. Kitty took a breath and nodded excitedly, "I am willing. "

Bai Wutong smiled, personally awarded him the medal of senior backbone researcher, and said to others: "After the power station is established, daily electricity consumption will become a common thing. I hope everyone will continue to work hard to create a new world for the lives of the people. .”

"Remember the instructions of the Empress."

The lighting tool for the absentees who go to the mine is still the torch, which is inconvenient. Using the kitten’s charging device, flashlights and headlights can be mass-produced, making it safer and more convenient for the absentees to go to the mine.

Bai Wutong asked He Jinchuan to develop high-illumination flashlight headlights and set up temporary charging stations in the mining area. When the flashlights and headlights are out of power, they can be charged on the charging stations.

The kitten heard it from the side, and another idea appeared in his mind, what if there was a portable replacement charging device? If absenteeism encounters a temporary power outage on the way to the mine, can it be replenished in time?

The use of different filaments can make the wick show different states. After a week of hard research and experimentation, He Jinchuan finally produced a portable flashlight and a headlight for mines. Zhao Yuan borrowed it for research and designed a bicycle. lamp.

On the basis of He Jinchuan's improvement of the wick, the kitten transformed the kitten doll into a kitten sitting on the lamp. The cute kitten

A lamp with a hat grows out of its head, which is novel and cute.

The kitten tried it for a few nights. Compared with jumping and dim kerosene lamps, it is convenient and tasteless, and the light is much more stable.

He felt that the device for pulling the wire was too inconvenient. If the wire was broken, Zhang Tiantian had to carry it back to find him.

The kitten stayed up all night and improved the pull wire device into a button switch.

Just press the button once to turn on the kitten light, and press it again to turn off the kitten light.

He was very satisfied with his setting of the button switch, and even asked He Jinchuan to have a look.

The switches designed by He Jinchuan for flashlights and headlights are toggle settings. When he saw the button switch of the kitten, he highly appreciated it. Hurry up and apply for a patent."

Kitty thought this was not a big achievement, but He Jinchuan said: "If you don't register, people will get ahead, and later people will use it to publicize your achievements, and you will vomit to death. Go and register. It won't take much trouble." Son."

He Jinchuan was teaching him to avoid future troubles. Kitty accepted his kind suggestion, but Zheng Guo, who was in charge of registering patents, was dumbfounded. In just a short time, Kitty had already registered three patents with him!

Zheng Guo had a look of disbelief, and the kitten was extremely calm. Seeing the badge worn by the other party, he clicked his tongue secretly, and the official rank was even higher than him.

Zheng Guo couldn't help being more polite, "Your patent evaluation is at the national level and cannot be sold without authorization, but you will get a lot of subsidies every month, as well as income from various patent sources. You can get these subsidies every month Go to the bank to confirm the withdrawal."

Bai Wutong gave 10% of subsidies for national patents. Seeing these amounts, Zheng Guo couldn't help but wonder why he didn't have the brains of a kitten.

The kitten was not short of money, he took the bankbook given by Zheng Guo and looked at it calmly, then went to Zhang's house with the kitten lamp.

At the youngest age, the kitten became the most senior backbone researcher in the scientific research department, which made Mrs. Zhang proud for a long time, and she is still full of spring, as if she was several years younger.

Even the head of the Zhang family praised her for her foresight. If she was a little late, the kitten would have stepped through the threshold right now, and this marriage might not be possible.

As soon as the kitten came, the servants of the Zhang family all enthusiastically invited him in.

Soon, Zhang Tiantian rushed out like a whirlwind, and said happily, "Come here!!!"

After the kitten entered Qinghe University, he could not see the tail all day long. Zhang Tiantian hadn't seen the kitten for several days.

Now everyone says that she picked up a treasure, Zhang Tiantian is also very proud.

The kitten nodded, and handed her a big cloth bag.

Zhang Tiantian took it, "What is this?"

The little cat said: "Doll lamp."

Zhang Tiantian opened it and saw that there was a tall hat on the head of the kitten doll, and there was a big glass wick in it. Every stitch and thread seemed to be made by him. She said excitedly: "Thank you, it is very cute, I like it very much .”

Hearing that she said she liked it, the kitten felt relieved, and stretched out his hand to press the switch on the chest of the kitten doll, and the light on the kitten doll's head turned on with a "swish".

This is much brighter than the fruit wick she saw last time, like a small sun suddenly appearing on the head of a kitten doll, which is dazzling.

Xiaoxue was taken aback, and the other servants also stared wide-eyed, their faces full of disbelief.

Zhang Tiantian said excitedly: "It's so bright, I really like it!"

The kitten smiled slightly, "You can put it next to the bed for lighting at night, if the battery is out, you can bring it to me, and I will charge it for you."

Last time, Zhang Tiantian just said casually, and the kitten was really developed. No wonder he was able to research the laboratory, which is too powerful.

Zhang Tiantian smiled all over her face, "I really like it so much, there is no gift in the world better than what you gave me."

Girlfriends will definitely envy her when they see it.

No, she cannot be seen by others, she must be well hidden.

The kitten will go to Qinghe University in a while, and after talking to Zhang Tiantian, he left Zhang's house in a hurry.

As soon as he left, Mrs. Zhang and Zhang Jiaxiu all ran over to watch the gift that the kitten gave Zhang Tiantian.

Although the workmanship of the kitten doll was crude, the lamp on the head that was as bright as the sun really surprised them beyond words.

Zhang Tiantian stared and admired, "It's really beautiful, so beautiful!"

Mrs. Zhang also thought it was so beautiful, Master Zhang and Zhang Xiu were also envious, and they really wanted a lamp like this.

Master Zhang said eagerly: "Daughter, how about borrowing from Dad for one night?"

This thing is really rare, if it can be sold, it will definitely make a lot of money, but the head of the Zhang family has also inquired, all the core parts of this thing are produced by the imperial court, he can't make money at all Business.

However, to be able to find such a powerful son-in-law as Xiaomao is his luck in these years.

Zhang Tiantian held her baby in her arms, "No, this is a kitten for me, you can only look at it, you can't take it away."

Patriarch Zhang was deflated, and Mrs. Zhang couldn't help but sigh, "It would be great if we could have such a thoughtful gift."

Zhang Xiu also echoed, "That's right, it would be great if someone gave me such a thoughtful gift sometime."

Zhang Tiantian heard what they meant, and smiled proudly: "The kitten said, everyone will be able to use it in a short time, and the imperial court is stepping up production!" Then said: "Don't ask for it, kitten I'm so busy, I don't have the time to do it for you."

Mrs. Zhang couldn't help laughing, "Hey, you got married so quickly, it seems that Tiantian's marriage is definitely the right one."

Zhang Tiantian blushed, and said shyly, "Mother, he was always nice to me."

Bai Wutong's study room also used a desk lamp. Looking at this bright desk lamp, her memory seemed to bring her back to the modern age.

Turning around and seeing the lovely Smelly sitting on the desk next to him writing and drawing, he couldn't help but smile a little.

Suddenly, there was a knock on the study door, "Come in."

Wang Momo brought a group of servants in and brought some exquisite afternoon tea.

Smelly raised his head, his eyes fell on the exquisite dinner plate, and found that there was a snack he liked, and he couldn't help licking his lips with his little tongue, with a greedy look on his face.

Bai Wutong walked up to him and picked up the little house he had just painted, "The painting is not bad, and the colors are beautifully used, how about my mother rewarding you with snacks?"

Smelly jumped off the table cheerfully, "Thank you, mother."

They sat together in front of the floor-to-ceiling windows, full of autumn colors, like a beautiful golden scroll.

Smelly took a bite

Little Dessert, looking at the slowly falling leaves, sighed in an old-fashioned voice: "It's autumn."

Bai Wutong laughed lowly, "Winter is coming soon, can spring be far behind?"

Smelly shook his head, "Not far." He just missed Daddy.

Knowing that he missed Tianbao, Bai Wutong was told by everyone not to mention it in front of her, so he touched his little head distressedly, "Smelly is going to be an older brother soon, do you like younger brother or younger sister?"

Smelly eyes lit up, and said decisively: "I like them all!"

Bai Wutong caressed his belly, which was bigger than ordinary people, and smiled softly, "With a brother like Choubao, they will be very happy."

Smelly raised his head high, "You won't be able to call me Smelly then."

"What's the name?" Bai Wutong smiled, "Lingyun Jun?"

Smelly proudly said: "Brother Smelly!"

Bai Wutong's smile deepened, "Well, Brother Smelly, our Brother Smelly is so cute."

Smelly finished his snack contentedly, then obediently returned to the desk, and quietly drew his drawings.

After Bai Wutong finished handling the general political affairs, Cui Shize handed over the memorial again, the cotton in the workshop was not enough.

Southern Xinjiang is only one-fifth the size of Lingguo, but the climate is diverse, and there is an area dedicated to cotton cultivation.

But the production in this area was not enough for the locals before they came to southern Xinjiang.

The Syrian people raise sheep, and wool can replace cotton, but the price of wool, as they purchase in large quantities, the Syrian people are not stupid, and the price has risen directly, and it has continued to rise.

If Bai Wutong hadn't ascended the throne as the Empress, Southern Border was still the territory of Ling State, and they could purchase a large amount of cotton from Ling State.

But now, it is obviously impossible to do business with Ling country.

They planted a lot of kudzu, but the linen or clothes made of kudzu are far less comfortable and breathable than cotton, and the rough craftsmanship is even abrasive.

The increase in the price of wool when the supply exceeds demand is caused by the market. Forcibly suppressing the price will cause dissatisfaction among the Syrian people.

But blindly accommodating their prices will also keep the price of cotton cloth high, and the common people can no longer afford cheap and comfortable cloth.

Now it is necessary not only to regulate the market price, but also to fully adjust the market demand.

In fact, the cloth made of cotton, wool, and silk is not cheap compared to the price of linen. In modern times, a short sleeve marked with 99% pure cotton is often very expensive.

Everyone is used to it, and synthetic materials such as chemical fibers are prevalent in the city.

Chemical fiber is the most common man-made clothing material. It is extracted from petroleum, and is named nylon, acrylic, etc. according to different materials.

It is a chemical compound in which petroleum is converted into a liquid through refinery processing, and then extruded to form chemical fibers. These fibers have many advantages, such as anti-ultraviolet, anti-pilling, abrasion resistance, etc., which just make up for the lack of natural fibers. place.

Therefore, many modern clothes, labeled pure cotton, actually add a lot of chemical fibers.

The supply of cotton was insufficient, and Bai Wutong immediately thought of oil as a raw material substitute.

A batch of oil was shipped last time, some fuel oil was extracted, and the waste was made into asphalt, and there are still some left.

Bai Wutong thought about it for a long time, anyway, he has already got this job, and it is not too surprising to use oil to make clothes.

She asked people to burn the oil waste at high temperature and tear it into filaments, and called in Hai Dongli, another big boss in the scientific research room.

Hai Dongli is a mute, before Bai Wutong discovered his talent, he always liked to tinker with some weird things that would go to heaven.

Everyone thought he was a lunatic, only Bai Wutong said he was a genius after seeing the flying mold he made, and recruited him into the research institute.

Hai Dongli is very grateful to Bai Wutong for his recognition, and is also very satisfied with the environment of the research institute. He stays in the research room every day and often forgets to eat.

People give it a nickname, Big Bee, the kind that wants to go to heaven all day long.

After Bai Wutong found out, he specifically asked someone to be his assistant to take care of his daily life.

He is even more grateful to Bai Wutong, but he will do his best to research everything that Bai Wutong needs, and even explore the prototype of the engine according to Bai Wutong's guidance, which can directly skip the steam age.

Bai Wutong came looking for him suddenly, Hai Dongli's scruffy beard could be used as a broom, fearing that it would smoke Bai Wutong, he hurriedly washed and tidied up before coming to see Bai Wutong.

Hai Dongli can't speak, but his eyes are very bright and full of wisdom.

Bai Wutong shot straight in, and put the oil waste torn into silk in front of him, "I think its material can replace cotton and become the main daily fabric, what do you think?"

Bai Wutong has extraordinary courage, extraordinary intelligence, and mysterious aura that is unpredictable. Before Hai Dongli picked up the piece of petroleum waste, he felt that what Bai Wutong said was not a question, but a question. Affirmative.

He tugged at the silky oil waste, sniffed it under his nose again, and felt that his consciousness just now was wrong.

Such a black mass of petroleum waste with such a strong smell is still hard, how can it be made into a soft material that can replace cotton.

Hai Dongli couldn't guarantee it, and gestured with his hands, "I can try."

It is also impossible for Bai Wutong to let him study like a chicken without a head. If he does not have a general direction and does not know how long it will take to detour, he can master the real technology.

Bai Wutong handed the old drawings made in advance to him, "This is the metal casting purification method I read in an ancient book, I think you should be able to use it."

Although it is just a rough and simplified reminder, Bai Wutong believes that given him a little time, chemical fiber will not be too far away from entering thousands of households.

Hai Dongli took a look at the blueprint of Bai Wutong, and it was a process of transforming oil into some kind of substance, and then condensing it into a kind of resin-like high-grade compound, and extruding silk threads through extrusion. A form is drawn.

This process looks quite simple, but I don't know if it is as simple to operate.

Hai Dongli connected the drawings, and gestured to Bai Wutong again, "I will do my best."

Bai Wutong nodded, "I'm waiting for your good news."

Hai Dongli kowtowed and left the study.

Bai Wutong looked at the falling leaves outside the window. The process of making chemical fiber is actually not difficult. What is difficult is the mass production and operation of chemical fiber equipment.

This needs to overcome a lot of principles, I hope he can go well, otherwise, when the child is born, I will still be tired.

Hai Dongli returned to the research room, and many people brought him a lot of oil.

Others in the research room thought that he came up with something, which was appreciated by Bai Wutong and rewarded him.

They came over to watch the fun, but the whole room smelled like a lot of oil. They wanted to ask him what he was doing with the oil, but remembering that he couldn't speak, he held back the words.

Petroleum is flammable and explosive

For dangerous goods, Bai Wutong opened up a separate space for Hai Dongli in the backyard of the scientific research room for him to conduct experiments.

Haidong already has many experimental areas by himself, and now there is another one, which everyone is very envious of.

Haidongli didn't care about other people's curiosity, and devoted himself to the experiment of refining chemical fiber.

He repeatedly operated according to the steps on the drawing, and soon produced the spinning fluid, but the color and feel of the spinning fluid were not satisfactory, and even the bark clothing was softer than it.

Haidongli also did a lot of research on spinning fluids, and recruited female textile workers to get inspiration from them.

He also looked through various possible related books, and finally, in the teaching plan given by Bai Wutong to everyone to make white paper, he found the relevant mixing, filtering, defoaming and other processes to overcome the spinning fluid.

After a while, he finally got the snow-white spinning.

During this period, he also made a self-made spinning machine to quickly collect all the spinning, which is convenient for female workers to use directly.

When the female worker produced the first piece of chemical fiber fabric overnight, Hai Dongli could not help shaking his hands as he touched the soft and silky fabric like satin.

He succeeded, and he used the black oil to develop the cloth that the Empress wanted to replace cotton.

Hai Dongli danced excitedly, and other people in the scientific research room walked in, didn't look at the fabric he was holding in his hand, but walked towards several dark containers in the field, and asked, "Is this a new product you're researching?"
