Pet King

On a swaying boat, wearing headphones, closing your eyes, weakening the connection between the five senses and the outside world, and listening intently to the sound from the bottom of the sea, the whole person seems to sink into the bottom of the sea slowly and be bottomless. Surrounded by darkness, it was like returning to his mother's belly, his body suspended in chaos.

Darkness makes people more focused. The beauty of the undersea chants makes it impossible to feel the passage of time. However, when the weird voice sounds around, the eyes open involuntarily and the cold sweat returns to reality. Fortunately, I have not really been physically In the dark sea floor, there is no need to consider what kind of monster the sound just came from.

If experienced teachers and graduates of the College of Underwater Acoustic Engineering are here, using two or more underwater pickups, you can use the triangulation method to determine the degree of movement and direction of the target. I heard that senior submarine listening system officers and soldiers even Can identify the real body of hundreds of noisy targets in a short time.

Zhang Zi'an is not so talented, he can hear this is the minke whale's voice, because the minke whale's voice is very unique, and he knows that there are minke whales nearby. If you change to a rare whale, he can't be the first Time to hear it out.

He listened for a while and heard another suspected cetacean, but he was too far away to distinguish.

So he took off the headphones and hung it around his neck, and sank the underwater speaker into the water, but he did not sink as deep as the underwater pickup because the line was not long enough.

He turned on the speaker and started playing Shihua's singing.

Every time he played for a few minutes, he paused, put on his ears again, and listened to the sound of the sea floor. If he didn't pause, because the speaker was too close to the pickup, Shihua's singing would cover up all other sounds, and the result was that he couldn't hear anything. Here.

Yesterday he used the voice of Shihua to soothe the male minke whale. Unexpectedly, the song attracted the giant whale. Today he plans to do the same and try to bring in the giant whale.

This time he was mentally prepared to never be attacked by that giant whale again.

Yesterday the giant whale emerged to the surface without warning. It almost made him think that it was a submarine of any country, because it must have dived deep in one breath and couldn't see any trace of it on the water.

The giant whale was not easy to get along with. If it was approached to a dangerous distance again, today there is no minke whale to rescue him. He would overturn the boat and fall into the water. If these valuable instruments fall into the water, he would have to send his pants into the pawnshop.

However, he has the weapon of an underwater pickup. As long as the whale is within a certain range, he can spot its arrival in advance and take countermeasures to escape.

For example, this is like a cat-and-mouse game between a destroyer and a nuclear submarine, except that this destroyer is more discouraged.

This kind of thing is a test of patience. Think about the submarine sonars in war movies when they are on duty for half a day, listening to the sounds coming from the headset, and trying to appear before the sonars of the enemy submarines themselves. On the other side, what level of concentration is needed? With a little distraction, the entire submarine may be sunk by the enemy submarine.

Zhang Zi'an didn't have the patience and concentration, but fortunately he didn't need to listen too long.

After about the third pause, a strange noise suddenly came from the monitor-level headphones, mixed with the short boom of the minke whale. If he was not concentrated, he would probably miss it.

There are more than one minke whale nearby. The sound is chaotic and noisy, almost the same as the bargain at the vegetable market. I do n’t know what they are talking about. However, when this abnormal noise appears, the minke whale sounds like it is ringing a class bell. A moment. Immediately thereafter, the minke whale's voice burst out at a higher density, as if warning each other, such as the wolf coming.

No way, although the cetaceans have a certain degree of wisdom, they still stay in the era where communication basically relies on roar.

Zhang Zi'an cheered up, listened more intently, and nervously wiped the sweat from his palms on his pants, took a deep breath, and glanced at the handle of the motor.

He wasn't sure if the voice came from the giant whale, or something, and could only wait.

About half a minute later, the voice sounded again, closer than last time, and heard more real.

The target is moving very fast, and with the rumble, a huge object like a train is approaching.

Zhang Zi'an could almost imagine the attitude of a giant whale with its mouth wide open, and all the small fish and shrimp along the road would be swallowed in the mouth without any difference, and then the seawater would be discharged from the baleen.

In contrast, the sound from minke whales is weakening, and the number is also decreasing. It seems that they are moving away from the mysterious giant. It may not be because they are afraid of it, but it has eaten up all the food nearby. Other whales can only starve.

The sound was getting closer and closer, like a whistle that changed periodically. When it was large, it was small. Even when it was big, even his eardrum vibrated with it. When it was small, it was hardly audible.

Zhang Zi'an frowned, what was the sound of this? Is that giant whale?

He glanced at the instrument's LCD screen. The instrument was automatically recording and drawing sound waveforms, but he didn't have time to take a closer look at this time. The target came very quickly. He wasn't sure if a sound sample had been recorded long enough, but he had to leave right away, or he might repeat the scene from yesterday.

He took off his earphones, quickly rolled the fiber optic cable, and lifted the underwater pickup from the ocean floor. The 5o-meter fiber-optic cable can't be made so quickly. As he rolled it, he stared nervously at the undisturbed sea, fearing that a submarine-like body would suddenly pop up somewhere.

The underwater pickup finally slammed out of the water with some dark green algae entangled on it.

He lowered the pickup, started the motor with the fastest speed, adjusted the bow to the direction of the 6th ground, adjusted the power to the highest, and the propeller turned high.

The submarine galloped towards the shore.

At this moment he was still not completely at ease, and looked back as he opened.

puff!

Almost before he left for a minute ~ www.wuxiaspot.com ~ A huge water column gushed out from his position just now, and after it rose to the highest point, it hit the water like a heavy rain.

The sea was facing for one minute on both sides, and a huge body emerged from the sea.

Zhang Zi'an estimated that he had probably reached a safe sea area, then slowed down the ship and picked up a telescope to observe.

The giant whale shook its tail, and if no one was swimming on the surface for a while, there seemed to be nothing interesting. After a few breaths, a fierce man plunged into the water and disappeared again.

Zhang Zi'an finally breathed a sigh of relief. One was to retreat because of "doing" today, and the other was to confirm that the source of the sound was a giant whale, and not something else. ...
