4.6 Billion Year Symphony of Evolution

The 'gland cells' have completed their evolution. When the water level drops, Lynn let them divide quickly and combine them into the cortex to start making their own carapace.

Lin found that the food she usually eats, including various wild cells or other multi-cellular organisms, originally contains substances that can make carapace, and does not necessarily have to go to the cracks in the rock to find materials.

These substances were originally regarded as waste, Lin would squeeze the waste from the digestion to the surface of the cortex and discharge it.

There are many kinds of substances that can make up a shell, but because it is more urgent now, Lin chooses a random combination.

The water surface decreases very slowly, but Lin ’s cells act just the opposite. They will be covered with a white shell on the cortex in the body. Although they are not as strong as other hard shell creatures, they are used to protect the light. Very enough, because it is not composed of living cells, no matter how the ultraviolet rays are irradiated, Lin will not feel pain.

The chitin will slowly harden after being secreted. Lin puts the entire body of the aircraft carrier covered with the same shell. As for the swimming tentacles and sledge hammer tentacles, Lin lets them retract into the aircraft carrier. Lin does not want to Adding shells to the tentacles will greatly reduce flexibility.

After finishing, Lin has no pain at all, and the carapace can effectively avoid the damage of ultraviolet rays.

But now the water surface is still declining, and Lynn ’s crisis has not been lifted. It does not want to be completely exposed on the water surface, so that it does not know what will happen.

As the water level decreases, the temperature here becomes higher and higher, probably because of the relationship between the crystals, the heat they absorb from the light affects this water area.

Flatworms have been swimming around here. They prey on the wild cells in the water that were killed by ultraviolet rays. These cells were originally hidden in the rock cracks. As the water temperature increased, the cells all swam out and became flat. Worm food.

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

Could it be ... this circular area was created by flatworms?

Lin originally had some doubts that ordinary stones cannot form such a neat shape, there must be something wrong in it.

Thinking, Lin immediately activated the spout behind the aircraft carrier and rushed towards a huge rock ahead!

Numerous stones collapsed under the impact of the aircraft carrier, and this huge stone was directly knocked out of a huge depression by Lin.

Sure enough.

Flatworms can use mucus to stick sand to their bodies, then they can also use mucus to combine other things. These giant stones are actually flatworms that are glued together with countless small stones!

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

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

Lin finally escaped. Fortunately, the water surface has not lowered to the point where the aircraft carrier cannot move.

After exiting the megalithic circle, Lin saw a clear downward slope ahead, leading directly to deeper waters.

It seems that I accidentally arrived at this position close to the water surface in the dark.

The water surface will be high during the night, but it will be lower when the day comes. Flatworms should make these megalithic circles at night.

The reason they made the megalithic circle may be to prevent predators, or it may be that the crystals can be easily heated inside, or to design a trap to let large creatures like Lynn enter, and then be killed by ultraviolet light, so they There will be a lot of food.

... The third reason seems unlikely.

Lin slowly shook her tentacles and swam down the slope to the deep water. It felt that the trip also had a lot of gains. If not, Lin might not have tried to evolve the carapace.

The carapace is a very strange thing. Lynn found that the original food contained many kinds of substances that can make up the carapace. They are collectively referred to as Lin's "chitin". By changing the combination of chitin, Lin can change the shell. The hardness, toughness, hardening time after secretion and many other different effects.

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

It turned out that Lin's hammer also contained chitin. At that time, she only combined the hardened cells together. Lin did not know to separate the shell from the cells.

Now the successful separation of cells and shells can increase a lot of hardness, and will not directly attack the cells.

Thinking about it, Lin had swam back to the deep beach area. The cold water and the gloomy light made Lin feel relieved again.

However, Lynn will not be so willing to give up, he will go back and evolve a perfect way to fight ultraviolet rays.

Now, eat more first.

On this trip, Lin saw the rich biological population around her, and she no longer worried about the lack of food.

Lin observes the surrounding beach, there are a considerable number of various creatures, including leaf-shaped insects that Lin is familiar with, and some unseen creatures.

Those creatures that I haven't seen have different shapes, but they all have one thing in common ... small in size.

Lin began to release devourers to hunt these creatures, while the aircraft carrier and guardians were responsible for dealing with larger ones, such as leaf-shaped insects.

Lin was eating these creatures while increasing the shell of the aircraft carrier. Lin discovered many problems during this period. The thicker the shell, the greater the burden on the aircraft carrier. No wonder the thick shielded worm can only crawl on the ground Too.

And if the hard shell is wrapped around the whole body, then the hard shell itself cannot be enlarged with the aircraft carrier. This situation is also quite troublesome ...

Creatures like leafworms or buckworms, how do they keep the carapace and body growing at the same time?

Moreover, the discharge of waste materials is more troublesome.

When cells digest food, they always produce something that cannot be digested. This kind of thing will let it pass through the cell's nutrient exchange system and finally be sent to the cortex to be discharged into the water.

Finally, Lin decided to cover the carapace only above the aircraft carrier, and still use the original combination of hardened cells below, and the tentacles did not cover any carapace to maintain flexibility.

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

But Lin now just solidified the green cell breeders, adding two layers of openable shells on both sides of its transparent center, controlled by the internal muscle connection.

As for other combinations with armor ... wait until night.

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

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

Although the surroundings were not completely dark, Lynn had lifted the lantern. It swam across the beach and the rocky area, and it soon saw the ring-shaped boulders again.

One of the boulders was knocked out of a hole by Lin. It can now see that the flatworms are repairing it. They collect sand and debris from the surroundings and fill the gap.

It seems that the repair work is progressing very slowly. It has been a day, and they have only repaired less than half.

Now, they may never be repaired.

Lin rushed up and shattered the hole being repaired, and then released a large number of devourers, hunting the flatworms around.

Because flatworms recede in the day and become cold in the water, their movements are much slower, and the devourers can easily catch them.

Lin ’s aircraft carrier and guards completely destroyed the entire boulder ring, and the flatworms fled to the distance.

Lin did not chase, but stopped the aircraft carrier near a piece of crystal, and began to study the new combination in her mind.

Lin wants to make a new cell combination. It needs to have ultraviolet resistance and a strong carapace. Lin wants to use the whole organism to make a special plan.
