4.6 Billion Year Symphony of Evolution

Chapter 18 Login Preparation

The 'glandular cells' have completed their evolution. When the water level dropped, Lin let them divide quickly and assembled them into the cortex to start making their own carapace.

Lin found that the food she usually eats, including various wild cells or other multicellular organisms, already contains substances that can make carapaces, and she doesn't have to go to the cracks of rocks to find materials.

These substances were originally regarded as waste, and Lin would squeeze the remaining waste from the digestion to the surface of the cortex to discharge, but it seems that it has to stay now.

There are many kinds of substances that can make up the shell, but because it is urgent now, Lin just picked one to combine.

The speed of the water surface lowering is very slow, but Lin's cell actions are just the opposite. They will cover the cortex with a layer of white chitin in the body. Although it is not as strong as other hard-shelled creatures, it is used to protect against light. Very enough, because it is not composed of living cells, the ultraviolet rays will not make Lynn feel pain no matter what.

The chitin will slowly harden after being secreted. Lin covered the entire body of the aircraft carrier with the same chitin. As for the tentacles for swimming and the tentacles of the giant hammer, Lin let them indent into the aircraft carrier. Lin did not want to. Putting shells on the tentacles will greatly reduce flexibility.

After the completion, Lin felt no pain at all, and the carapace was very effective in avoiding UV damage.

But now the water level is still falling, Lin's crisis has not been resolved, it doesn't want to be completely exposed to the water surface, so I don't know what will happen.

As the water level lowers, the temperature here also gets higher and higher, probably because of those crystals, the heat they absorb from the light affects the waters.

Flatworms have been swimming around here, they prey on the wild cells in the water that were shot to death by ultraviolet rays. These cells were originally hidden in the crevices of the rocks. As the water temperature increased, the cells all swam out and became flatworms insect food.

Lin looked at them, and an idea suddenly appeared in her mind.

Couldn't it be... the ring-shaped area was created by a flatworm?

Originally, Lin had some doubts. Ordinary stones could not form such a neat shape. There must be something wrong with it.

Thinking about it, Lin immediately activated the water jet behind the aircraft carrier and dashed towards a boulder in front of her!

Countless stones collapsed under the impact of the aircraft carrier, and this boulder was directly knocked into a huge depression by Lin.

Sure enough.

Flatworms can use mucus to stick sand grains on their bodies, and they can also use mucus to combine other things. These boulders are actually made by flatworms with countless small stones!

Lin didn't observe it carefully at first, but it now knows that it's actually quite easy to go out.

Then, Lin asked the guards to come, and it used its limbs to easily dig a hole in the boulder enough for the aircraft carrier to pass through.

Lin finally managed to escape, but fortunately the water level hadn't dropped to the point where the aircraft carrier couldn't move.

After exiting the boulder circle, Lin saw an obvious downward slope ahead, leading directly to deeper waters.

It seemed that he had inadvertently arrived at this position very close to the water surface in the dark night.

The water level here is high during the night and lower during the day, and the flatworms are supposed to make these boulder circles during the night.

Maybe the reason they make the boulder circles is to keep predators out, maybe so that the crystals can easily heat up inside, or to design a trap for large creatures like Lynn to enter and then be shot alive by UV light so they can There is plenty of food.

... The third reason seems unlikely.

Lin slowly swayed her tentacles and swam down the slope to the deep water. She felt that this journey had also yielded a lot. If not, Lin herself might never have tried to evolve a carapace.

The carapace is a rather peculiar thing. Lin found that the original food contained many kinds of substances that could form the carapace.

They are collectively referred to by Lin as 'shell matter'. By changing the combination of shell matter, Lin can change the shell's hardness, toughness, hardening time after secretion, and many other different effects.

This aspect is quite complicated, and Lin still needs to study, but after a successful combination, it will be much simpler in the future.

It turned out that Lin's hammer also contained husks. At that time, only hardened cells were combined together. Lin didn't know how to separate the shell from the cells.

The successful separation of the cells and the shell is now able to add a lot of stiffness without directly attacking the cells.

While thinking about it, Lin had already swum back to the deep beach area. The cold water and the dim light made Lin feel at ease again.

However, Lin will not give up like this, it will go back and evolve a perfect set of methods to fight against UV rays.

Now, let's eat more.

During this trip, Lin saw the rich biological population around her, and she no longer worried about food shortages.

Lin observed the surrounding sandy beach, there were quite a number of various creatures, including the leaf insects that Lin was familiar with, and some creatures she had never seen before.

Those unseen creatures come in all shapes and sizes, but they all have one thing in common...small.

Lynn began to unleash the Devourers to hunt down these creatures, while the Carriers and Guardians took care of the larger ones, such as leafworms and so on.

While devouring these creatures, Lin increased the shell on the aircraft carrier. During this period, Lin discovered a lot of problems. The thicker the shell, the greater the burden on the aircraft carrier. No wonder the thick-shelled round shield worm can only crawl on the ground. .

And if the hard shell covers the whole body, the hard shell itself cannot grow in size with the aircraft carrier, which is also quite troublesome...

How do creatures like leafworms or Buckler worms keep their carapace and body growing at the same time?

Moreover, it is more troublesome to discharge waste.

When cells digest food, there will always be some indigestible things, which will be sent to the cortex through the cell's nutrient exchange system and finally discharged into the water, but it is difficult to squeeze out if the shell is covered.

In the end, Lin decided to only cover the top of the aircraft carrier with the carapace, and still use the original hardened cell combination below, and the tentacles were not covered with any carapace to maintain flexibility.

Of course, this is only done for the aircraft carrier itself. For the new arms, Lin can create a terrifying thing with full body armor.

But Lin now only solidifies the breeder who feeds the green cells, and adds two layers of openable and closable shells on both sides of its transparent center, which are controlled by internal muscle connections.

As for the other combinations with armor... let's wait until night.

In this way, Lin hunted the creatures on this beach and waited slowly until the night approached, and Lin swam to the previous place again.

Lynn called it a 'shoal', which means a place close to the water.

Although it wasn't completely dark all around, Lin had already raised the lantern, and it swam across the beach and the rocky area, and soon saw the ringed boulders again.

Lynn knocked out a hole in one of the boulders, and he can now see flatworms repairing it, filling in the gap by collecting sand and debris from around it.

It seems that the repair work is progressing quite slowly, and it has been a day and they are less than half repaired.

Now, they may never be repaired.

Lin rushed up and smashed the hole that was being repaired, and then it released a large number of Devourers to hunt down the surrounding flatworms.

The flatworms move much more slowly because the day recedes and the water becomes cold, and the devourers can easily capture them at this time.

Lin's aircraft carrier and escorts completely destroyed the entire surrounding boulder ring, and the flatworms fled to the distance.

Lin did not chase, but stopped the aircraft carrier near a crystal, and started researching new combinations in her mind.

Lin wanted to make a new combination of cells, which needed to be resistant to UV rays and have a sturdy carapace, and Lin wanted to use the whole creature for a special plan.
