4.6 Billion Year Symphony of Evolution

After ten minutes in the next chapter~

Lin did not consider how long it took for Leviathan to follow the helmet fish into the entrance of the river.

Leviathan certainly doesn't care about what salt is. Other creatures because when they swim, the organs in the body will constantly exchange various elements and nutrients with the water outside, so if there is any strange change in the water, they will Can't stand it.

However, Leviathan does not have a system for directly exchanging nutrients with water. Although it has the ability to absorb water and spray water, it does not pass its own blood or other circulatory system. Leviathan relies on a small unit to collect water for itself. Nutrients and foods, which are evolutionary types of collectors, are capable of separating the various harmful and innocious substances in the water in detail, and can also determine which substances Liviathan itself needs now.

That is to say... when entering the river, let the collectors collect more salt, and collect less water.

Leviathan swam deeper with the group of helmeted fish. There were few creatures in the river. Only some small creatures were on the sediments of the river. No predators could threaten the helmets.

In addition to Lin...

I don't know how long the helmet fish should swim, so Lin made an eyeball on the back of Leviathan, let Leviathan float to the surface and observe the changes in the land.

Leviathan never made eyeballs during this period of his life. It seems that he relies solely on the sense of smell and touch. Lin feels this is incredible.

Originally, the hot ultraviolet rays now seem to have no lethality. Even though the white light is still bright, Leviathan has no feeling of floating near the water.

The land on both sides of the river looks like some square big stones, blocking the vision of Lin, but there are some green things standing on the rocks, they look like a hard and thin tentacles, the end Have a branch.

They seem to have officially climbed onto the land. Like seaweed, these are the evolutionary forms of food light cells. They are completely different evolutionary routes from common organisms. Although they have a blood vessel-like system, they never Ken evolved the heart, muscles, brain and other organs. They don't move because they don't have muscles. They can only use the water to spread the cells for reproduction. The response to the surrounding environment is very slow. Even so, they are no more active than others. There are brain creatures to be poor.

Almost all of them contribute to the manufacture of oxygen. Although they are slow to respond, they can respond to brain-like creatures that quickly and like to eat them and produce various strategies. This is quite wonderful. Climbing the land should also be a shun. One of the eater's strategies.

These creatures can already have another word to describe them... 'plants', which is no different from the fast-moving ‘animals’.

But Lynn itself has both plant and animal characteristics, which is really interesting.

Leviathan has been following the helmet fish and has reached a special area.

The waterway in front is covered by stone walls formed by huge stones, but this is not the end of the river, because the gap between the stones indicates that the river can continue to go up, but these stones somehow fall in the center of the river, the river Give it a break,

The destinations of the helmet fish are obviously not here, but they are not able to penetrate the gap of the stone, so they swim on the water and jump to the top of the boulder exposed to the water.

The helmeted fish swung their fins and bulky heads, trying to climb through the boulder that interrupted the river.

Why don't they just lay their eggs here? Are you going to climb over?

Looking at the helmet fish that kept jumping on the boulder, Lin felt a little puzzled, but it also proved that the ultraviolet light does not have any lethality.

So what about Lin? Also jump up? Lin looked at Leviathan's life record, and now it doesn't seem to have any land capabilities. In the 100 million years of life, it has not been close to land.

However, Leviathan had occasionally fallen to the land. Leviathan climbed back into the sea alive, maybe he could go up and try it. Even the fish with fins could climb, Leviathan. There is no reason not to work.

Thinking, Lin let Leviathan float to the surface of the water, then slammed into the spout and jumped out on the rock.

Although Leviathan now has only two tentacles, the suction cup on the top can provide great strength, even if dragging the three-meter body on the land.

Leviathan is surrounded by hard-working helmet fish. It is 10 meters away from the water. Although Leviathan is huge, it is faster than the helmet fish with the help of suction cups. When Lin climbed in half, there were some monsters in front...

The oblong body is more than one meter long, with a serrated tong on the end of the forelimb. The tail is curved and has a sharp hook at the end. Obviously the meat eater, this creature comes from an inconspicuous small limb. Lin had seen them before, but I didn’t expect them to climb the land now.

They also have their own name ‘Bronde scorpion’.

It’s a weird name. There are three of these nephews. It seems that I’m already ready to ambush the helmets here.

This can be dangerous...

There are a total of eight eyeballs in the head of Bronde's nephew. Lin doesn't know how their eyesight is, but they are obviously staring at Leviathan.

I feel troublesome...

Leviathan is huge, and these scorpions seem to be a little jealous. They dare not rush to the front, but they are very well dispersed and surround Leviathan in three directions.

Leviathan does not have a new type of land combat, but Lin can still rely on the old method of combat, Leviathan's exit is on both sides of the body and the head, except for the tail, it has no dead ends.

emission!

With a strong acid bomb, he directly hit a scorpion in front of Leviathan, and it was painfully twisted and turned back, while the other two directly circumvented Leviathan to catch the nearby helmet fish. .

They do not seem to be surrounded by cooperation, but separated from the beginning?

Lin didn't think too much. He took the opportunity to climb into the water quickly. Even with the method of launching the bomb before, it was very troublesome to face the three.

Here, it is the spawning ground of the helmet fish, a wide circular water area, which should be called a 'lake'.

After Leviathan, there were also many helmet fish jumping into the lake one after another. The few Bronte scorpions also caught a few at most, and could not stop the helmet fish from coming here to lay eggs.

The helmeted fish swam to the sediment at the bottom of the lake. They first used a burrow to dig a small pit. Each pair of fish had its own small pit, and then began to release a large number of cells.

One is round, very large, about one centimeter, the other is ultra-small, with a tentacle-like small tail, only as large as a normal single cell. There seem to be two words to describe the difference between 'male and female'. .

The release of round cells is female, while the release of small cells is male, and the combination of male and female can create offspring with both advantages.

The helmet fish will die after releasing the cells. This is exactly the same as the flat fish. Lin found that most creatures have a set life, but they don’t just break down older cells like Lin, their life will end the whole individual. All cells, starting with the brain first, then slowly the whole body will die automatically.

They are not attacked or infected with viruses, all of which are determined by their own cells. A creature can only live for a certain period of time, and then they must die and give their position to their offspring.

The life expectancy of a flatfish is about 10 years. Although they may die earlier because of viruses or parasites, they will definitely survive for ten years, because the cells in the body must be dead at this time. The helmet fish are rather peculiar. They are set to die only after the spawning is completed. They will not die before.

The bodies of these helmeted fish will not be wasted, they will become food for newborn fish.

Lin came here not to see them breed. It wants to find a base here, which is also a good study of the difference between this and the sea.

Lin’s current base is very different from the previous one, mainly a spherical center point with a diameter of 30 cm, and then it will extend to the surrounding to extend the green carpet and eventually cover the entire area.

The structure of the green carpet is also much simpler, mainly two transparent shells, which contain photosynthetic cells and some small units for defense.

The green carpet will not have any effect on the helmet fish. Lin now rarely attacks other creatures. Observing them is more valuable than eating them.

When the base was put down, Lin suddenly felt a special feeling...

this is……

The base has some tentacles with strong tactile abilities. This is specially made by Lin to calculate the changes in the surrounding environment. By collecting information such as seafloor vibration and water temperature, it is possible to calculate what changes will occur in the future environment. Prepare in advance.

Lin had just felt a little strange feeling in the moment of the base.
