The blood vessels worked well after the construction, but Lin found some minor problems. It is difficult for cells inside the blood vessels to get oxygen, so the action will become sluggish.

Lin couldn't make a hole in the blood vessels, so that the things inside would flow out, but the cells in the blood vessels did not rely on their own activities but moved quickly through the water flow inside, so Lin did not care so much.

Lin's devourers have also been renewed. They have a vascular structure, but there is no heart. Instead, there is a muscle cell in the depths of the mouth and a storage capsule that connects the blood vessels. The devourer can collect the crumbed food. In this case, the capsule will contract, and the internal food and water will be squeezed into the vascular system, and the cells in the blood vessel will be decomposed and the nutrients will be transmitted to the whole body.

Excess water is circulated back into the sac in the blood vessels and is expelled when the devourer opens his mouth next time.

The plan to resurrect the Shield worm was put on hold, because Lin couldn't make so many cells filled into the shell of the Shield worm, and the heart and blood vessels were already consumed a lot, and it needed to find more food.

But this cold lasted for a long time, although it didn't affect Lin, but it meant that other cells would not appear, so there was no food, even though the fat cells were long enough to support them, but If you make another thing that is about the same size as the aircraft carrier, it will consume more than 70%. Lin does not want to consume so much reserves. What should I do if I encounter any danger again?

Maybe it can self-digest the aircraft carrier and then build a new base in the shell of the Shield worm?

No, Lynn doesn't want to rely on other creatures like this. It wants to grow a hard shell. If you live in it, it's hard to evolve a high-hardness skin.

What should I do now?

Go out and find food?

Then use a huge diggers to dig out?

It seems that it is too slow, and Lin hopes to get some more powerful ice-cold structures, like the round shield worms dig very fast...

Right... The Shield worm does not use the limbs to dig the ice. It seems to be smashing the ice with the semi-circular carapace of the head, but it requires huge size and strength.

In this case, only the modified aircraft carrier.

Lin’s aircraft carrier itself is a cylindrical body, which is very suitable for impact. Kelin does not want to use the aircraft carrier itself to collide. Instead, she forms two huge tentacles on both sides of the aircraft carrier. The front end of the tentacles is composed of a solid circle. Shaped, with a serrated structure called 'hammerhead', the tentacles consist of a large number of muscle cells that can exert a powerful force to hammer the ice.

Originally, this kind of structure Lin thought very early, but because the continuous hammer will consume a lot of muscle cells, the energy supplement time is too long, the efficiency is not very high, but after the vascular system, Lin can wave the tentacle while The energy is continuously added to the muscle cells, and the efficiency is much stronger than before.

After the construction, Lin began to start the aircraft carrier. The aircraft carrier itself has two tentacles for swimming, and there are huge water spray holes at the back end. It can also move very quickly. If it is not frozen around, the round shield worm is basically I can't hurt it.

After leaving a part of the cells in the round shield worm shell, Lin began a journey of crushing ice.

Before the aircraft carrier swam to the ice, the hammered tentacles slammed on the ice wall. Under the tremendous force, not only was a hole in the ice wall, but also numerous cracks appeared around it.

It's really effective, it feels like the round shield worms.

Lin let the aircraft carrier continue to sway with the hammer, completely smashing the ice crystal in front of it, and pulled out a passage that allows the aircraft carrier to move.

Then Lin also hardened the head of the aircraft carrier, so that it can not only hammer and ice, but also itself.

Lin didn't want to do this because she was afraid of hurting the vascular system in her body, but now it looks like there is no problem, because there is also a vascular system in the hammering tentacles, and it has not been hurt when I flew.

The big eyeball on the head of the aircraft carrier was degraded by Lin, and it was changed to form a small eye tentacles on the side of the aircraft carrier head to observe.

This is a lot easier to move forward on the ice.

Should I continue to move down? Lin felt that the wild cells should hide in the sand below, maybe it was warm and the ice could not freeze there.

Thinking, Lin changed to move forward, and continued to easily crush the ice. Although the ice layer will have different hardness, it is not a problem under the attack of hammering tentacles. It may take a long time to reach the bottom. The beach is gone.

strange?

After crushing a layer of ice again, Lin’s eyes showed an unusual sight. There was no place on the beach yet, but there was an ice-free area.

This is an ice cave large enough to accommodate three aircraft carriers. There are no signs of excavation on the surrounding ice walls. Lin does not know how this formed. Lin slowly swam into the open space among the ice.

Strange place, why is there such a place? Ice can't dissolve itself like this. Is it something that a creature has dug? But I didn't see that kind of creature.

When Lin was wondering why it was formed, she suddenly found some small dots moving above the surrounding ice wall.

what is that?

The eyeballs on the side of the aircraft carrier could not be seen clearly. Lin sent out the small devourers in the aircraft carrier. When they swam near the ice wall, they found that some of the moving small dots were some cells. They were almost exactly the same color as the ice. Easy to see.

These small cells are spread all over the ice wall, and Lin doesn't know what they are doing, but in general the food is right.

Lin didn't think too much, let the devourers start hunting them, and Lin let the aircraft carrier release more devourers, ready to sweep the cells out.

The devourer quickly swallows the cells on the ice wall. These cells have no defensive power. They look like ordinary round shapes. They are small, but they can make a weird thing to escape the devourer.

They can be drilled directly into the ice, without relying on any mining methods, but directly into it.

The small holes drilled out by the cells, the devourers are completely inaccessible, and can only give up hunting.

It’s strange, how do they do it? Lin carefully observed them. From the eyes of the smallest devourer, it can be seen that the cells seem to secrete a liquid that instantly dissolves the ice crystals around the body and can therefore enter and exit the ice.

So, is this hole so made by them? Then this kind of cell should be called... ‘soltolytic bacteria’.

The ice-solving bacteria are hiding in the ice, and they seem to be shaking happily there.

Hey!

At the next moment, Lin’s giant hammer tentacles slammed on the ice wall. This not only shattered the ice wall, but also blew out the ice-solving bacteria hidden inside, and then the devourers quickly mixed them into the ice. The small cells in the middle are swallowed up.

The ice-solving bacteria knew that it was not safe to hide in the ice, so they fled together in the depths, and Lin immediately crushed the ice again and chased them in the direction of their escape.

Although these ice-solving bacteria can be drilled in ice, the speed is very slow. The speed of the ice-carrying aircraft is not as fast as that of Lin’s aircraft carrier. Almost every time, Lin can take out a lot of ice-solving bacteria from the ice. Zhilin directly allows large devourers to bite into the powder by swallowing them together with the ice.

Lin just hammered them out of the wall and moved forward. However, after Lin didn't move forward for a long time, it suddenly found himself entering the water again, and there was no ice in front.

Going into the ice hole again? No, no.

Here is the vast waters, and Lin has left the ice knot area.

what is that?

In front of Lynn’s eyes, there was a strange sight.

In the vast waters, it is still empty and empty, but among the sand below, there are many things that Lin has never seen before.

Most of these things are flat or round shapes, and the surface is covered with striped protrusions. Some of them are lying on the sand, some are standing in the sand. After seeing it for a while, Lin confirmed that it is a creature, because they are almost motionless. But as there is water flowing through them, their bodies begin to shake and reach out from the body, waving in the flowing water.

These creatures should also be multi-cellular combinations. They are very abundant and almost all over the beach. It seems that the round shield worm does not eat monomer cells for a reason. It should be better at eating these multicellular organisms.

Where do these multicellular creatures come from? Lynn has been a single cell that has been seen for so long. Since when, have other organisms also seen multiple cells?
