Pet King

Zhao Welder was very careless, and provided little useful information. He repeatedly sighed that he was unlucky, and because he was not very clear about his mind, the car spoke repeatedly.

Zhang Zi'an made an excuse to end the call with Zhao Welder.

Combing through the information that he currently knows, he suspects that a certain organism in the fish tank caused a large-scale poisoning incident, but he has only two or three percent of the uncertainty. It is uncertain whether it should be the case. If it is wrong, it is okay to be ignored The key is to delay valuable time.

Centec saw him thoughtfully and asked, "Did you find anything?"

"Xiao Zhang, if anything is found, despite the frankness, you can't let go of any doubt now." Director Chen encouraged. Obviously it was the bright spring of March in Yangchun. The weather was neither cold nor hot, but he and Shengke were sweating.

Ordinary police officers visited the surrounding residents for suspicious characters in recent days, and called for monitoring in the community; the biochemical special police team took turns to wear a heavy protective suit to enter the woodworker's home for a carpet-like search; the dog police were executed to block the scene If the biochemical special police team is unable to find the source of the poison, it may be necessary to send police dogs into the room to search for suspicious objects.

The most troublesome thing is that it is not common toxins that cause damage, and the various test strips, reagents, and detectors carried by the biochemical special police team are difficult to exert their effects.

Someone kept talking to Director Chen through the walkie-talkie. The pressure from the superior made Director Chen almost anxious. Although his heart was extremely distressed, at least on the surface, he still maintained a kindness.

Zhang Zi'an calmed himself and said to Director Chen: "Director Chen, I suspect that there is something wrong with the fish tank in Wang Mugong's house."

The faces of Shengke and Director Chen froze at the same time.

"Zhang Zi'an! You can't be kidding at this time!" Shengke said positively.

Director Chen thought a little more, and asked, "You mean, someone put the poison source into the fish tank quietly?"

"No, it's not like that." Zhang Zi'an shook his head. "The fish tank itself is the source of poison."

Sheng Ke and Director Chen looked at each other with suspicions in their eyes. If it were not for Zhang Zi'an who had helped the police in several cases, they would have taken him aside long ago and had no mood to listen to his nonsense.

Zhang Zi'an also knows that the general public does not understand aquatic creatures, and even the old players of sea fishes may not really understand them. His words sound like a lot of things to ordinary people, but in fact some aquatic creatures can actually cause Such serious consequences.

Under the dark blue sea, there are still strange creatures that many people cannot imagine.

"You mean, some kind of fish in the fish tank is poisonous?" Director Chen confirmed.

"It could be a fish or something else. It's unclear for the time being. Unless you can see it with your own eyes, you can't be sure." Zhang Zi'an said.

However, it is not easy to see it with your own eyes, because the fish tank is full of water, it is very heavy, and it is difficult to lift it downstairs. Besides, if the fish tank is really a source of poison, it may be dangerous to lift it out.

Director Chen closed his eyebrows and stared at the closed window of Wang Mugong's house, weighing the pros and cons repeatedly.

Both Shengke and Zhang Zi'an did not disturb him with interest.

"How confident are you?"

After half a ring, Director Chen asked tightly.

Zhang Zi'an stretched out three fingers.

Sancheng's certainty seems very low, but in the current clueless situation, it already has the capital to gamble.

Director Chen was silent for a moment and waved his hand suddenly, "prepare him with a gas mask and protective clothing."

"Director Chen, this ..." Sheng Ke wanted to object, and it was too dangerous to involve an ordinary person with no experience.

"Xiao Zhang, would you like to go in and try it out? Of course there must be some danger." Director Chen confirmed to Zhang Zi'an.

Zhang Zi'an glanced at the policeman with a dog in the standby state. If he refuses, I am afraid that a police dog will be dispatched next. The police dog's tolerance to toxins is much worse than that of humans.

"Okay, come on." He nodded in agreement.

Shengke saw that he was determined to do it, and sighed, and stopped opposing.

The biochemical special police team brought a full set of spare protective equipment, put on Zhang Zi'an protective clothing, put on a gas mask, and carried an oxygen cylinder, and then explained to him something that needs attention, and warned him not to run around after entering the house. .

It was very cool weather, but after wearing heavy protective clothing, his entire body seemed to be wrapped in silkworm cocoons, it was stuffy and hot, and his joint movements were greatly restricted. The sounds around it seemed to be blocked and blurred.

The special police helped him check the air pressure and determined that there was no air leak, and he gestured to him to follow them into the unit building.

Zhang Zi'an moved his steps awkwardly, twisted his body and glanced at Director Chen and Sheng Ke again. They waved at him, their eyes were expectant and disturbed.

There are no elevators in the old residential buildings, and every step is very strenuous. The ears are filled with their own breathing and slight hissing. This is the sound of the high-pressure gas slowly released from the oxygen cylinder.

By the third floor where Wang Mugong lived, Zhang Zi'an's body was sweating, and the beads of sweat rolled from his forehead down his cheek, or stuck on his eyebrows, and itchy, but it could n’t be scratched. Feeling itchy.

He forcibly diverted his attention and turned his eyes to Wang Mugong's house.

There are many shiny instruments stacked at the door. Biochemical special policemen are busy testing and moving things on the spot. When they see Zhang Zi'an's unfamiliar face, they can't help but look through the headset and ask, "Who is this? of?"

"No, he is not a policeman, he is ... Director Chen is here to help." The person who brought Zhang Zi'an explained.

"Help?" The special police leader's tone was full of doubts, but since it was brought by Director Chen, he wouldn't say much. Perhaps this person has something unique, "What's your suggestion?"

Zhang Zi'an saw the fish tank in the corner of the living room at a glance.

It should be said that from the perspective of the placement position, Wang Mugong ’s fish farming level is much better than that of Zhao Welder and Wu Dian. That position is cool and protected from light. With a high-brightness metal halide lamp, there is a led lamp for balanced spectrum next to it, relying entirely on artificial lighting.

"I'll go over to the fish tank," he said, pointing his finger at the fish tank. "I think the source of the poison is in the fish tank."

"In the fish tank? We have checked the fish tank visually. There are no foreign bodies." The special police leader shook his head.

Since toxins are rare and unknown in nature, commonly used test strips, reagents and detectors are ineffective, and biochemical special police have to consider all possibilities, even the strong radioactive elements hidden somewhere in the room.

"It may just be invisible." Zhang Zi'an said, seeing that others did not object, he slowly moved his steps and came to the fish tank.

The water in the tank is clear and the objects in the water are clear at a glance. There are a few dead fish floating on the water, and beautiful corals are attached to the live rock of the salamander. Whether it is setting or coral breeding, there are advantages.

It stands to reason that the fish and corals should not be dropped immediately after turning over the tank. Perhaps Wang Mugong stopped when he felt uncomfortable when he was halfway through, and gave Zhao Welder a few fishes to send him away.

The special police leader did not dare to let him leave his sight, wondering if he would disturb things, and came over and asked, "Do you think these fish are problematic? Even if they are poisonous fish, you will not poison yourself?"

Obviously, there are no moving things in the fish tank except the fish. And in common sense, no fish is so toxic.

Zhang Zi'an said, "Come, help the hand, pour out some water from the fish tank, and then take out all the stones in it! Be careful! The water in the fish tank may be very toxic. Don't pour into the drain!"

Since everyone is wearing bulky protective clothing, this fish tank is very large, and it is difficult to remove stones without scooping out water.

The special policemen were not very willing to obey the command of his common people. After asking Director Chen for help, they reluctantly started to use all the containers found in the house and poured out about half of the water in the fish tank.

Immediately afterwards, the stones in the fish tank were taken out piece by piece and placed on the cloth.

Every time he took out a piece, Zhang Zi'an would carefully check the corals attached to the live rock, but these corals are more common species and should not be the culprit.

The special police in charge of taking pictures took the stones seriously and responsibly.

Another person is responsible for the video.

The fish tank was empty. There was nothing but the bottom sand that was stirred up.

Everyone's eyes were on Zhang Zi'an, meaning: What now? Let's say there are no foreign objects in the fish tank.

Zhang Zi'an stared deadly at the last piece of live rock that was taken out, with some brown, unbelievable umbrella-shaped corals attached to it, radial stripes on the umbrella cover, and a circle of slightly creeping antennae growing evenly on the umbrella Cover edges.

Because the fish tank is placed against the wall, these brown coral-attached living rocks are located on the side against the wall, which is invisible from the front and can be easily ignored.

It is almost certain that Wang Carpenter did not know that these brown corals were quietly growing in his fish tank, because they were ugly and no one would buy them intentionally.

Zhang Zi'an couldn't guess whether Wang Mugong saw the hidden corals when he turned over the tank last night, and whether he tried to clean them up. In short, they exploded.

He breathed a sigh of relief, pointing at the brown corals and saying, "The source of the poison you want is them."

In common people's common sense, the brighter the more toxic the more unsightly the more secure the thing.

"What is this? Coral?" The SWATs said suspiciously. "Are you sure?"

Zhang Zi'an nodded, "These are the sand anemone corals. Do n’t underestimate them. The toxins they release are called rock sand anemone toxins. They are ranked 8th in the world's toxin rankings, higher than it. It is botulinum, radioactive element plutonium-210, diphtheria toxin and the like. As long as 21 micrograms can kill a 70 kg adult 21 micrograms. The unit of measurement is not grams, not milligrams, but micrograms, which is 0.000021 grams. . "

He also pointed to the metal halide lamp above the fish tank, which was intensely light and also emitting strong heat. "These corals sensed danger and released toxins in the water. They poisoned other creatures in the fish tank first, and the toxic seawater was turned by the halogen lamp. Evaporated into the air and was inhaled by Wang Woodworking's family, Zhao Welder and firefighters, causing poisoning. "

In the list of common venomous organisms on the Internet, sand coral anemone corals can never be found, but the toxicity of rock sand anemone toxins released by them is more toxic than the infamous blue ring octopus or snail It is several dozen times stronger, and there is no medicine to dissolve, even slight inhalation can cause acute poisoning.

In fact, rock sand anemone toxins are not unique in poisoning marine fish players. These dangerous corals are often attached to live rocks and sneak into people's fish tanks. They slowly grow up, and once they feel life threatening, they will release toxins.

If Wang Mugong's lamp is not a metal halide lamp, the evaporation rate of seawater will be slower and the degree of poisoning will be lighter. After all, this kind of lamp is too hot, like a little sun.

Although the SWATs have extensive experience in handling dangerous goods, this is the first time that they have heard such terrible corals, and they all heard nothing.

"Report! Director Chen, the source of the poison has been found, it is ..." The leader reported to Director Chen by radio. He glanced at Zhang Zi'an, "It is the coral in the fish tank."

"What? Repeat it!" Director Chen couldn't believe his ears and thought he had heard it wrong. With such a big news, the culprit is coral?

"It's not an ordinary coral, it's a very poisonous coral called a sand group anemone coral." The team leader tried to explain.

Director Chen was surprised and relieved at the same time. No matter how the source of the poison was finally found, the experts sent by the Provincial Department could get back home, and the nature of the incident had changed radically.

He then asked: "Is there a possibility of deliberate poisoning?"

The leader was unable to answer this question, and signaled that Zhang Zi'an would answer.

"Reporting to Director Chen, I don't think it was intentional poisoning." Zhang Zi'an said that ~ www.wuxiaspot.com ~ should have been accidentally brought in from the living stone bought by Wang Mugong. "

"Live rock? Where did you buy it?" Director Chen sternly instructed: "Check where he bought the live rock, and then go to that shop. How can such a dangerous thing be bought and sold at will!"

Zhang Zi'an secretly regretted that the aquarium where the living stone was sold to Wang Mugong was going to be unlucky. Somehow such a big thing would be difficult to continue to open the store in the future.

"Director Chen, how do you know these corals?" The leader asked.

Director Chen pondered for a moment and said, "Seal it up and bring it back to the bureau, pay attention to safety."

The SWAT officers carefully packed live rocks and corals in sealed containers.

There is no more Zhang Zi'an here. He went downstairs by himself, walked out of the door of the unit, took off his gas mask, and let the breeze blow his sweat and cheeks.

"Great, Xiao Zhang!" Shengke came over excitedly.

"Fortunately, no shame." Zhang Zi'an laughed.
