After the multifunctional landing ship flew on the blue sea for a while, it finally stopped in the air. The impact flow formed by the plasma engine made ripples on the sea surface.

As the belly of the landing ship opened, a circular device stretched out. After it rotated in a circle, a missile-sized device fell down.

The way it fell into the water was like the best diver in China, with only a little splash of water. As the flashing blue strobe light gradually disappeared, the deep-water sonar detection device was quickly falling into the depths.

[The average depth of the target sea area is 13,500 meters. The suspended height of the deep-water sonar is 6,000 meters from the sea surface. The No. 1 sonar boost engine has been turned on and is expected to reach the target depth in 5 minutes. 】

"Lord, I heard Commander Kane say that your planet also has a sea?" As soon as the loudspeaker finished speaking, Leader Tarna asked Xiang Chuge. He seemed to be very interested in the solar system. He kept asking these questions along the way, which seemed purely pure.

Small talk questions.

"Yes! It is very large, but it is not as deep as the sea in front of us. Even now, we still have not figured out the secret of the earth's deep sea.

It was impossible to do it before, but now there is no time!”

"No time?" Tarna seemed to have difficulty understanding the deeper meaning of Chu Ge's words.

"Well, let's leave the area of ​​our home to future generations to slowly investigate. We need to set our sights further afield."

"Oh!" The lizard man leader nodded. The way Chu Ge looked at him, he couldn't figure out whether the other party really understood or just pretended to understand.

[Sonar No. 1 arrives at the predetermined location, the sonar signal is stable, and the landing ship moves to the next release location.]

20 minutes later, the landing ship's wheeled delivery device was retracted into the belly, and all three sets of deep-sea sonar were launched.

Right in front of Chu Ge and the others, a screen clearly displayed the real-time operations of the data processing team. A standard triangle was quickly formed on the screen based on the signals from three sets of sonar.

According to the most primitive triangulation positioning method, the launch coordinates of the deep submersible are clearly displayed on the electronic map with a radius of 100 kilometers.

[The coordinates of the deep submersible have been transferred to the automatic navigation system, and the landing ship is heading to the final working location.]

After broadcasting this message, the landing ship started again and headed towards the destination. It quickly reached the predetermined position, hovered in the target sea area for a while, and then the landing ship began to slowly land.

When everyone saw that the waves outside were almost hitting the portholes, the landing ship stopped.

Through the monitoring system, Chu Ge and the others saw that the belly of the rear cabin of the landing ship slowly opened, and the black submersible entered the water little by little with the help of several sets of mechanical arms. With the last sudden move, the deep submersible was completely submerged in the water.

After a burst of bubbles, it sank completely, and the rear cabin slowly closed. Then the screen showed that the signal was connected, and the screen reappeared.

Chu Ge saw the underwater world of the Tantavar Star Ocean for the first time.

"Through our data analysis, our target organisms spend most of their time in the water layer between 8,000 meters and 10,000 meters.

Therefore, the target water area of ​​the deep submersible is about 7,000 meters from the sea surface. After reaching the predetermined position, it will remain stationary and wait for prey to come.

During the submersible dive, the signal connection with the landing ship will be maintained. After the passive sonar detects the signals of those creatures, the signal connection will be cut off until the hunt is successful."

Kane reported the next action to Chu Ge, who stared at the surveillance screen and nodded mechanically.

No wonder Chu Ge didn't bother to answer. He found that the underwater world of Tanvar Star was not what he imagined.

What is the earth's underwater world like? The clearest places in the sea water can reach up to 200 meters, and human eyes can basically not see sunlight.

The water depth is 200 meters to 1,000 meters. Some creatures with very keen vision can still see sunlight, but no earth creatures can carry out photosynthesis.

The water depth exceeds 1,000 meters, and no known living creatures on earth can see sunlight. They either use bioluminescence or no longer rely on vision to find food.

The water depth exceeds 3,000 meters. Except for a few deep-water creatures that occasionally pass by, the world here is a dark realm...

So when the deep submersible dived to 1,000 meters and the aquatic creatures swimming around could still be seen on the surveillance screen, Chu Ge began to widen his eyes.

He didn't pay attention to the strange aquatic creatures swimming across the picture from time to time. He was observing the environment here.

"Is the searchlight turned on?" Chu Ge asked.

"Let me see, no, the effect of the searchlight is not like this. This is the real environment,,,"

Commander Kane said as he saw the real-time dive height displayed on the right side of the screen, 1,500 meters! He seemed to know what Chu Ge's question was.

The two stopped talking until the submersible descended to 5,000 meters, and they both looked at the leader of Tarna at the same time.

"Has it reached your preset depth?" the lizardman leader asked, looking at the two of them.

Kane shook his head.

"Then,,, what do you want to see me do?"

"Is your seabed like this too?"

"yes."

"I mean brightness, light. Why is it bright underwater and not black?" Kane seemed a little anxious.

"Does the bottom of the sea have to be black? The ocean on our planet Tantalvaar has always looked like this. Bioluminescence, what's so strange about it.

Have you never been to the forest at night?"

The lizard man stared at Kane, as if he was puzzled that Kane would ask such a ridiculous question.

Chu Ge held his mouth and did not laugh. Only then did he start to pay attention to the aquatic life that the deep submersible passed by from time to time. It seemed to be quite lively here. The aquatic species did not seem to be as numerous as the earth's oceans, but they were still a small number.

After observing for a minute, Chu Ge suddenly discovered an interesting phenomenon. The large aquatic creatures here seemed to have a luminous gland.

Some simply hold the luminous gland in front of themselves through a curved cartilage-like support, just like holding a lantern.

Chu Ge couldn't help laughing when he saw these large creatures with big light bulbs running around. They were so cute.

"Have you noticed that the swimming fish-type organisms, crustaceans, chaetomids, coelenterates, microorganisms and even some algae here are sources of light?

That's why the deep sea here is as bright as day.

Looking at it this way, this seems to be very consistent with Darwin's theory of evolution. Luminous glands are already one of their standard organs, just like our ears and mouths.

Those creatures that can survive here without these functions have evolved more advanced organs, such as our hunting objects, the cloak.

It has evolved an ultrasound organ, so the luminous glands and eyes are naturally useless..."

When Chu Ge said that Cao Cao had arrived, the surveillance screen showed that the hunting target had appeared, and passive sonar quickly determined the target's location and quantity.

A total of 12 big cloaks entered the triangle area. They swam very fast and quickly reached the red line set by the deep submersible.
