4.6 Billion Year Symphony of Evolution

In the calm and boundless waters, huge creatures are slowly advancing in a floating way here ...

The life at the base was calm and boring, so Lin turned her attention to Leviathan.

It has been two days and nights since departure, and Leviathan has swam across the vast gray sandy beach and the seabed made of stones. Unlike before, Lynn mainly swims deep.

Leviathan has now arrived at a new place, which is also a sandy beach, but the grains of sand are finer and white, and there is a creature that Lynn has not seen all over the area.

They look like inverted jellyfish, with a short, thick, round body attached to the sand, and a large number of barbed cell tentacles to capture prey.

Lin knew there was a word to name them ... 'Anemone'.

Anemone is a fairly simple creature with no vascular heart and a digestive sac in the center of the body, which is responsible for digesting food brought in by tentacles.

Creatures with no research value at all, Lin doesn't like to eat these creatures, because they usually have little content after removing the poisonous thorns.

Leviathan lowered the swimming height and slowly floated on the beach. Lin named the tentacle with a mouth under it as 'bite tentacle', but just like the devourer, it is only used to crush things. Not responsible for digesting food.

Leviathan generally does not use its own eyeballs, but the eyeballs floating beside it are responsible for observation.

Lin suddenly saw that there was movement in the gravel below.

Leviathan stretched out his tentacles, biting something in the sand and pulling it out.

That is a trilobite.

There are many types of trilobites. This is the fifth species that Lin has seen. This is particularly small, and the shell is also very thin. The mouth that bites the tentacles can completely bite it in the mouth and crush it.

Shells and cells scattered from the bitten trilobite, Lin will release a soldier called a collector to collect, it is about the size of a devourer, this creature is mainly a worm-type structure, the whole is very flexible Sex, can swallow a lot of food, expand into a ball, the body is filled with strong dissolving liquid, responsible for swallowing food and then dissolving, and finally return the nutrients to Leviathan.

Collectors can also squirt dissolution fluids from the body to attack, although they are not designed to attack themselves.

After eating the trilobite, Leviathan continued to move forward. It had enough fat stored in it. Lin planned to take a longer trip without stopping.

Lin mainly wanted to see some special environment, an environment it had never seen before.

The sprinkler system speeded up, and Leviathan swam quickly on the white sand, but it stopped quickly because the environment that had never been seen suddenly appeared in front of it.

The beach in front of him seemed to be cut into two sections. A huge rift appeared in front of Lynn. It was long enough to extend beyond Lynn's field of view, and wide enough to put down hundreds of Leviathan.

Lin has never seen this kind of landscape ... is this a "trench"?

Lin found that the latest new words seem to be more boring. What kind of trench does not have any momentum, it might as well be called Rift Valley directly.

... What is the momentum?Never mind.

Leviathan swam over the trench and looked down at the floating eyeballs, only to see the rift extend straight down until the light could not reach the dark abyss.

Would you like to take a look?

Lin was hesitant, but wasn't this trip to explore the unknown?

Go on!

Leviathan slowly descended, there were many anemones adhering to the rock walls on both sides of the trench, and there were some small trilobites swaying beside them. There were many single-celled organisms floating in the water. The area.

For a while, the light around Leviathan was getting darker and darker, and Lynn released a swimming lantern. This non-fixed light allowed Lynn to see everything around him.

As the depth of the trench is closer, the surrounding creatures are less. Until the surrounding becomes dark like night, it is difficult for Lin to see any creatures other than single cells.

Lynn didn't stop, and continued to go to the darker depths, it released more lanterns, these small swimming spots spotted some anemone-like creatures on the rock wall.

They have anemone-like tentacles, but the body below is not thick and round, but a thin long handle, which does not seem to be called anemone, but has a new name of "sea lily" .

I think the name is pretty good.

Leviathan swam close to the rock wall, trying to pull out one to eat and eat, and as soon as Lynn approached, they would instantly shrink into the rock cracks.

The rock wall of the trench is not generally hard, and it seems that it can't be eaten.

There are many sea lilies on the rocks here. Lin found that they are of different types, and some will not shrink.

Lynn ’s interest in researching them was not great, Leviathan continued to dive deeper, and he wanted to see if there were anything else interesting.

The more Leviathan descended, the more Lin discovered a problem, which could be called 'stress'.

The floating small eyeballs and lanterns were first affected by this feeling. They became difficult to move, as if squeezed by some powerful force, and some even died directly because they could not bear the pressure.

Where does this pressure come from?It seems to be everywhere, is it ... the reason for the water?

Lin recovered all of them, and opened a hole in the edge of Leviathan's disc-shaped shell, which contained Leviathan's own eyeballs.

It is protected by a layer of transparent shell material, which can protect it from harm, but it limits its field of vision because it cannot move at will.

Lin also released a lantern covered with a hard shell to resist the pressure in the water.

But deeper, the effect of pressure becomes more and more obvious, even Leviathan itself is affected, and the swimming pattern of water absorption and spraying becomes more and more difficult, even in Leviathan's carapace. Road cracks.

The pressure is terrible.

It seems that he can't continue to go down, but Lin doesn't want to give up. It has already calculated how this pressure works and also knows what kind of structure can resist this pressure.

Of course, Lin did n’t want to change Leviathan ’s structure, so it created a new class of arms with an oval body filled with water inside, and a layer of not thick shell outside the body. This class of arms does not have any swimming ability. As soon as it was released by Leviathan, it sank deep into the trench with gravity.

This shape and structure should be able to effectively resist pressure, but the most basic basis for resisting pressure is to fill the interior with the same substances that create pressure around it, so that no matter how much force it cannot press.

Leviathan went back, and Lynn had to repair the wound on her body. As for the exploration at the bottom of the trench, leave it to the little ellipse.

Its name is 'warhead'.

After a while, when Leviathan quickly floated out of the trench, the "warhead" also heard the feeling of hitting an object. It seems that it has sunk to the deepest point.

At this time, the shells on both sides of the warhead's body opened, and a total of six arthropod legs protruded from it. The arthropod legs were also filled with water, so they would not be crushed by the pressure. The eyeball and a lantern appeared at the same time.

The eyeballs and lanterns are covered by a thin transparent shell, and the shell is filled with water. This method can effectively resist pressure. Now the "warhead" has no cracks at all.

It moved the small articulations around the body and started the journey of the dark abyss.

Because the warhead is filled with water, it occupies the position where it should have placed muscles or blood vessels, so it can't move fast at all, but it is only used for exploration, and it does not need to be too fast.

The ground at the bottom of the trench is composed of rocks. Under the illumination of the warhead lantern, some single-celled creatures first entered Lin's field of vision.

Surely they are everywhere?Except on land.

Lin found that the trench cells were much larger than the ones above, and it was indeed a pressure-resistant structure filled with water.

Just as Lin was studying them, a light suddenly lit up in the distance, the brightness far exceeded the light emitted by the warhead itself, and seemed to be emitted by some huge creature.
