MTL - 4.6 Billion Year Symphony of Evolution-v2 Chapter 20 Air storage and immune system

The journey on land is not meaningless. Although there is hardly anything on the land worth remembering, it still has some useful knowledge.

For example, air.

Lin discovered very early that the air in the water would float upwards. Lin never cared about this thing. Until now, Lin suddenly remembered why they would go up instead of going down? Can they resist gravity?

This is not the case, but the air is lighter than water, so they will be squeezed out by the water, so the land on the high ground is all air.

Now Lin has reduced the speed of the aircraft carrier because it covers the carapace, and the swimming is not as flexible as before.

But... what happens when you add air?

In the aircraft carrier, Lin created an elliptical sac-like combination called airbag, which is filled with oxygen. This structure can make the aircraft carrier much lighter. It should be no problem even if the whole body is covered with armor.

The airbag has two small pipes, one connected to the blood vessel, which can oxygenate the blood vessel, and one small hole that protrudes from the cortical carapace. This tube is usually closed, and when it floats to the surface, it can Control the airbag to expand to inhale.

Lin also created a small cell combination called a gas reservoir, which looks like a small balloon that swims outside the body. The gastor relies on small tentacles around the body and uses small hollow tentacles to absorb small water. bubble.

The gas reservoir also has a hard shell outside the body and can devour the sand to balance the weight of the body.

After the aircraft carrier covers the complete hard shell, oxygen intake becomes more difficult. When the gas collector is full of oxygen, it can be returned to the carrier to release it. In addition, it can directly inflate the airbag when Lin does not want to float to the surface.

However, the current situation is that although Lin added the airbag, but did not add the whole body shell, because the reserves of the shell material is not enough.

At the same time, Lin added a balloon to the guard's shell, but even then it did not float, just the degree of 'floating'.

In addition, Lin also covered a large number of blasters and acid injectors in the inner layer of the defender's hollow tail. This originally empty position is now used to dissolve and combine various shells.

The combined shells are then taken out by a new type of ‘painter’ for transport to the aircraft carrier, and the painter can directly coat the shells in various places to form the shell.

Guardians are now more like factories that make carapace.

Lin is still considering using gas to attack, but now there is no good idea.

The aircraft carrier slowly swims with the guards. Lin is observing the surroundings. In this deep water beach, there are single cells everywhere, whether in the gravel or elsewhere, the life here is so vibrant, and the ridiculous The land forms a sharp contrast.

The number of single cells seems to be much larger than before. In the past, there was no such scene in the water everywhere, so there will be many creatures that do not move in the water, waiting for the cells to float for themselves.

When I thought about it, I found some multi-cellular creatures in front of them. They looked like a few tubes inserted in the sand. The tentacle-like body protruded from the tube and captured the single cells that floated around.

This is called 'tubeworm'.

Feeling Lin's approach, its soft tentacles instantly retracted into the tube underneath. Lin knocked on the pipe hidden by the pipeworm and found it to be hard. It must have been made of shell material.

Lin has a relatively high amount of shell material extracted from food. Some shellless creatures contain only 1% or less of shells. If you want to quickly build a set of armor, Lynne must go into the gravel to get the raw materials. Or attack those shelled creatures, and this tubeworm is the ideal target.

The next moment, Lin's hammer slammed into the shell of the tubeworm.

The tubeworm was very thin and not very hard. The shell was only hit and cracked.

Lin didn't care if the other's shell was hard and hard because it dissolves and reorganizes the shell and adjusts the shell to its ideal hardness.

Oh...

The shell of the tube worm broke under the attack of Lin, and the soft organ inside was exposed.

Next, it is the work of the devourers, who bring the crumbs of the shell back to Lin, and by the way, the soft body of the tubeworm is torn off, and the nutrients and shells are recycled.

The structure of the tubeworm is quite simple, and there is no interest in Linlian's research.

The small shells were sent directly to the guards for dissolution and reorganization, while Lin’s aircraft carrier turned to attack nearby tubeworms.

It takes about ten tubeworms to make a carapace covering the entire aircraft carrier.

The carrier's tentacle Lin did not intend to cover it, which would affect flexibility.

When Lin was playing the next tubeworm, the tubeworm did not retract, but twisted the body and spewed a lot of cyan liquid.

These liquids are made up of countless tiny particles that are revealed under Lin's special eyeballs.

……virus?

The liquid contains a large amount of linear virus, and a small amount is the original cell of the tubeworm.

Will tube worms release virus attacks? No, it may be that the tubeworm is infected with a virus.

In the current environment, viruses are actually not common. Although they can destroy cells, they will also kill the virus in reverse. In an environment with a lot of cells, the virus is suppressed.

Only individual multicellular organisms like this tube worm will cause a large-scale outbreak of the virus. After all, they will eat what they have, and it is not surprising to eat the virus.

Lin's aircraft carrier never directly obtained nutrients, no matter what was transported back by other arms, so the aircraft carrier has almost no possibility of being invaded by viruses, and Lynn has already thought of a good way to deal with the virus.

Lin will let the gastor take turns to get oxygen in the outside activities, so there will always be some gas storage people will wander around the aircraft carrier, some viruses drift in with the inspiratory tentacles of the gas collector, and drill into the cells in the inner layer of the tentacles. in.

When the virus penetrates into the cell, Lin can immediately feel it, so it immediately covers the body around the body with a rapidly hardening shell, which is completely sealed before the virus splits.

Finally, the hardened cells are removed and easily solved.

In addition, it is also a good idea to let the cells die immediately. The virus seems to only proliferate in living cells.

Lin expands the vascular structure and allows the gland cells to swim inside, which allows them to transport the shell material to the body at any time, allowing cells anywhere to quickly absorb the shell and harden. This set can be effective. Isolation of viruses or other small creatures.

Lin ignored the virus attack and easily destroyed the tubeworm completely without any wasted recycling.

Next...

Lin is preparing to attack other tubeworms, and suddenly an urgent signal enters its mind, and the guards behind the aircraft carrier are attacked.

Lin felt that the defender was dragged by a powerful force far beyond itself. When the aircraft carrier turned around, she saw only one bunker.

Was it pulled into the sand by a certain creature?

Lin regrets that she didn't put the eyes on the guards. It can only accept that the guards are pressed tightly by the force, no matter how hard they struggle.

It should be a multi-cell creature that is about the same as or more powerful than the Shield worm, or it will not pull the Guardian so easily.

Do you want to try to dig it out?

The guards did not continue to be dragged deeper and should still be in a shallow position.

Lin is hesitant, no matter how it is based on the safety of the aircraft carrier.

However, it seems a pity that the loss of the guards.

Finally, Lin was still close to the bunker and dug up in the center with the carrier's tentacles. After the sand was removed, Lin could see the guardian's body.

In the second half of the guardian's body, the body was sandwiched by two large disc-shaped hard shells. Under strong pressure, Lin could feel that the guardian's body was almost broken.

Lin still remembers such creatures. There used to be a lot of place where the leaf-shaped worms appeared, and the shells were very hard, but Lin didn't see them moving. Isn't they a very powerful predator?
