4.6 Billion Year Symphony of Evolution

The journey on land is not meaningless. Although there is almost nothing on the land that is worth remembering by Lin, it still acquired some useful knowledge.

For example, air.

Lin discovered very early that the air in the water would float upwards. Lin hadn't cared about this matter until now. Lin suddenly remembered why they would go up instead of down?Can they resist gravity?

This is not the case, it's just that the air is lighter than water, so they will be squeezed out by the water, so all the land on high ground is air.

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

But ... what happens if you add air?

Lin created an elliptical bladder-shaped combination inside the aircraft carrier, called the 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 balloon has two small tubes, one is connected to the blood vessel, which can oxygenate the blood vessel, and the other is a small hole that protrudes from the cortical carapace. This tube is normally closed. When Lin floats to the water surface, it can Control airbag expansion to inhale.

Lin also created a small cell combination called a gas storage device. It looks like a small air bag swimming outside the body. The gas storage device relies on small tentacles around the body to swim and uses hollow tentacles to absorb small water bubble.

Gas receivers also have a hard shell outside the body and can devour sand to balance the weight of the body.

After the aircraft carrier covers the full hard shell, oxygen intake becomes more difficult. When the gas receiver inhales the oxygen, he can return to the aircraft carrier and release it. In addition, it can also directly inflate the airbag when Lin does not want to float to the surface.

However, the current situation is that although Lin has added an airbag, she has not added a full-body shell because the reserve of shell material is not enough.

At the same time, Lin also added an airbag to the guard's shell, but even then it failed to float, just to the extent of 'floating'.

In addition, Lin also covered the inner layer of the guard's hollow tail with a large number of burst balls and acid injectors. This originally empty position is now used to dissolve and combine various carapace.

Then the combined chitin will be taken out by a new class of soldiers called "painters" and used for transportation to the aircraft carrier. The painters can also directly apply the chitin to various places to form a carapace.

Guardians are now more like a carapace factory.

Lin is still considering attacking with gas, but there is no good idea now.

The aircraft carrier slowly walked with the escort. Lin was watching the surroundings. On the beach in this depth of water, there were single cells everywhere, whether in the gravel or other places. The land is in stark contrast.

There seem to be more single cells than before. There was no such scene in the water before, so there will be many creatures that are motionless in the water, waiting for the cells to come over and feed themselves.

Thinking about this, Lin found some multi-celled creatures in front of them. They looked like a few tubes inserted in the sand. The tentacle-shaped body protruded from the tube to capture the single cells floating around.

This is called 'pipeworm'.

Feeling Lin's approach, her soft tentacles instantly retracted into the tube below. Lin knocked on the pipe where the tube worm hid and found that it was hard, which must be made of chitin.

Lin ’s content of chitin extracted from food is quite at least. Some shellless organisms may contain less than 1% or even no chitin. If you want to quickly build a set of armor, Lin must get the raw materials from the gravel. Or attack those shelly creatures, and this tube worm is an ideal target.

The next moment, Lynn's hammer hit the tubeworm shell hard.

The tube worm is very thin and not very hard. The shell was cracked only after being hit for a while.

Lin doesn't care if the other person's shell is hard or not, because it can dissolve and reorganize the shell and adjust the carapace to its ideal hardness.

Click ...

The tubeworm's shell shattered under Lynn's knock, and the soft organs inside revealed.

Next, it is the work of the devourers. They bring the debris of the shell back to Lynn, and by the way, the soft body of the tube worm is torn to the sparse rotten, and the nutrients and the shell material are recovered.

The structure of the tube worm is quite simple, and Lin has no interest in research.

The small broken shells were sent directly to the guards to dissolve and reorganize, while Lin ’s aircraft carrier turned to attack the nearby tube worms.

It takes about ten tube worms to make a carapace that covers the entire carrier.

The tentacle Lin of the aircraft carrier does not intend to cover it, which affects the flexibility too much.

When Lynn hit the next tube worm, the tube worm didn't retract, but twisted her body and sprayed a lot of blue liquid.

These liquids are composed of countless fine particles, and under Lin's special eyeballs, they are undoubtedly revealed.

……virus?

The liquid contains a large amount of linear viruses, and a small amount of the original cells of the tube worm.

Will the tube worm release a virus attack?No, it may be that the tube worm is infected with the virus.

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

Only individual multicellular organisms like this tube worm will cause large-scale outbreaks of viruses. After all, they will eat whatever they float, and it is not surprising that they eat the virus.

Lin ’s aircraft carrier never directly obtains nutrients, no matter what is transported back by other arms, so the aircraft carrier has little possibility of being invaded by the virus, and Lin has thought of a good way to deal with the virus.

Lin will let the gas collector take turns to get oxygen, so there will always be some gas reservoirs who will wander around the aircraft carrier. Some viruses will float in along with the gas collector's inspiratory tentacles, and they will get into the cells inside the tentacle in.

When the virus penetrated into the cell, Lin could immediately feel it, so it immediately covered the cell body with a rapidly hardening chitin and completely sealed it before the virus split.

Finally, the hardened cells are removed, and it is easily solved.

In addition to this, it is also a good way to let the cells die immediately, the virus seems to only multiply in the living cells.

Lin expanded the blood vessel structure and allowed gland cells to swim in it, which allowed them to deliver chitin to the body at any time, allowing cells anywhere to quickly absorb the chitin and harden it. This set can effectively Insulate against viruses or other small creatures.

Lin ignored the virus attack and easily destroyed the tube worm completely and recycled it without waste.

Next ...

Lin was about to attack other tube worms. Suddenly an urgent signal entered her mind, and the guardian lying behind the aircraft carrier was attacked.

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

Was it pulled into the sand by some kind of creature?

Lin regretted not giving her eyes to the guardian. It can only now accept that the guardian is pressed tightly by that force, and she can't escape no matter how hard she struggles.

It should be a multi-celled creature that is similar to or stronger than the buckworm, otherwise it will not pull the guards so easily.

Would you like to dig it out?

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

Lin was hesitant. In any case, it puts the safety of the aircraft carrier first.

But ... it seems a pity to lose the guard.

Finally, Lin was still close to the bunker, digging up in the center with the carrier's tentacles. After pulling away some of the sand, Lin could see the body of the guard.

The second half of the guardian's body was sandwiched between two huge disk-shaped hard shells. Under strong pressure, Lin could feel that the guardian's body was almost broken.

Lin remembers this kind of creature. In the past, there were many places where leaf-shaped insects infested, and the shell was very hard, but Lin had not seen them move. Could they be a very powerful predator?
