4.6 Billion Year Symphony of Evolution

Ten minutes after the next chapter ~

………………………………

Lin didn't think about it for long, and let Leviathan follow the school of helmet fish into the entrance of the river.

Leviathan of course does not care about what is salted. Other organisms will constantly exchange various elements and nutrients with the water outside when they swim, so if there are any strange changes 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 and spray water, these waters will not pass through its own blood or other circulatory systems. Leviathan relies on a small arm to collect water for itself. The nutrients and food, which are the evolution of the collector, can separate various harmful and non-harmful substances in the water in detail, and can also judge how much substance Leviathan itself needs now.

In other words ... when entering the river, let the collectors collect more salt and less water.

Leviathan swims deeper with the school of helmetfish. There are very few creatures in the river. There are only small creatures on the bottom of the river. No predator can threaten this group of helmetfish.

Except for Lin ...

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

Leviathan never created eyeballs during this period of his life. It seemed that she lived purely on smell and touch. Lin felt this was incredible.

The scorching ultraviolet light originally seemed to have little lethality. Even if the daylight was still bright, Leviathan had no feeling of floating near the water.

The land on both sides of the river looked like some big boulders that blocked Lin's view, but there were some green things standing on the rocks, they looked like a hard and thin tentacle, the end There is a fork.

They seem to have officially landed, just like seaweeds. These are evolutionary types of light-eating cells. They and the common organisms take a completely different evolutionary route. Although they have a blood vessel-like system, they never Ken has evolved heart, muscle, brain and other organs. Because they do n’t have muscles, they ca n’t move. They can only rely on water flow to propagate reproductive cells. Their response to the surrounding environment is very slow. Even so, they live no different. The brain creatures are worse.

Almost all of them are responsible for the production of oxygen. Although they respond slowly, they can respond to those brainy creatures that quickly and like to hunt them and generate various strategies. This is really wonderful. Climbing on land should also be an escape from hunting. One of the eater's strategies.

These creatures can already have another word to describe them ... 'plants', which is not different from the fast-moving 'animals'.

But Lin herself has both plant and animal characteristics, which is really interesting.

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

The water channel in front is blocked by a stone wall formed by huge stones, but here is not the end of the river, because the gap between the boulders indicates that the river can continue to go up, but these stones somehow landed in the center of the river, and the river Interrupted,

The destinations of the helmeted fishes are obviously not here, but their size can't get through the cracks of the stone, so they swim up the water and jump to the top of the boulder exposed.

Helmets swing their fins and bulky heads, trying to climb over the boulders that interrupt the river.

Why don't they just spawn here?Just want to climb over?

Looking at the helmet fish constantly jumping on the boulder, Lin felt a little puzzled, but it also proved that ultraviolet light had no lethality anymore.

What about Lynn?Did you jump up too?Lynn looked at Leviathan's life record, and now it doesn't seem to have any terrestrial capabilities. In the 100 million years of life, it has not been close to land.

However, Leviathan once fell to the land by accident. Leviathan all climbed back alive into the sea. Maybe he could try it. Even the helmeted fish with only fins can climb over it. Leviathan There is no reason not to.

Thinking, Lynn let Leviathan float to the surface, then suddenly opened the spout and jumped out, falling on the rock.

Although Leviathan now has only two tentacles, the suction cup above can provide great power. Even if it drags a three-meter body on the land, it does not matter.

Leviathan is surrounded by hard-working helmet fish, and there are ten meters away from the water. Although Leviathan is huge, with the help of suction cups, it climbs faster than these helmet fish, but , When Lynn climbed halfway, some monsters appeared in front ...

The oblong body is more than one meter long. The forelimbs have giant serrated pliers at the end, the tail is bent, and the end has a sharp hook. It is obvious that the carnivorous creature comes from a humble small arthropod. Lin had seen them before, but they didn't expect them to be able to climb on land now.

They also have their own name 'Brondo Scorpion'.

What a weird name. There are three of these scorpions. It seems that they are ready to ambush the helmet fish here.

This can be dangerous ...

There are eight eyeballs on the head of Brondu Scorpion. Lynn does not know what their eyesight is, but they all stare at Leviathan.

Feeling in trouble ...

Leviathan is huge. These scorpions seem to be a little daunted and dared not rush forward, but they are well dispersed and surrounded Leviathan in three directions.

Leviathan has no new arms for land combat, but Lynn can still rely on the old methods of combat. Leviathan's troop is on both sides of the body and the head, except for the tail, it has no dead ends.

emission!

With a sour explosive bomb, he directly hit a scorpion in front of Leviathan. When suffering, he twisted his body and backed away, while the two next to him directly bypassed Leviathan to catch the nearby helmet fish. .

They didn't seem to be surrounded by cooperation, but separated from the beginning?

Lin didn't think too much. At this opportunity, she immediately quickly climbed into the water. Even if she used the method of firing explosive bombs, it was still very troublesome to face three.

Here 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 helmetfish jumping into the lake one after another, and the few Brondu scorpions would only catch a few at most, which could not prevent the helmetfish from coming here to spawn.

Helmet fish swim to the mud at the bottom of the lake. They first dig a small pit with their head armor. Each pair of fish has its own small pit, and then they begin to release a large number of cells.

One is round, large, about one centimeter, and the other is super small, with a small tentacle-like tail, only the size of a normal single cell. There seem to be two words to describe the difference between them. .

The round cells release females, while the small cells release males. The combination of males and females can create offspring that have both advantages.

Helmets die after releasing their cells. This is exactly like the flat fish. Lin found that most creatures have a set life span, but they do n’t just break down the older cells occasionally like Lin. Their life span will end the entire individual ’s life. All cells, starting with the brain, will slowly die of the whole body.

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

The lifespan of a flat fish is set to about 10 years. Although they may die earlier because of viruses or parasites, they will never survive for more than ten years anyway, because the cells in the body have been set to die at this time.Helmets are more peculiar, they are set to die only after spawning is completed, and they will not die before.

The body of these helmet fish will not be wasted, they will become food for newborn fish.

Lin didn't come here just to see them breed. He wanted to get a base here to see how it differs from seawater.

The base that Lin now manufactures is very different from the previous one, mainly a spherical central point with a diameter of thirty centimeters, and then it will extend to extend the green carpet around, eventually covering the entire area.

The structure of the green carpet is also much simpler, mainly a two-layer transparent shell, which contains photosynthetic cells and some small defense forces.

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

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

this is……

The tentacles inside the base have some strong tactile abilities. This is specially manufactured by Lin to calculate the changes in the surrounding environment. By collecting information such as seabed vibrations and water temperature, it is possible to calculate what major changes will occur in the environment in the future. Prepare in advance.

Lin had just felt a little ... strange feeling at the moment when she was at the base.
