4.6 Billion Year Symphony of Evolution

After the blood vessel is constructed, it works well, but Lin found some small problems. The cells inside the blood vessel have difficulty obtaining oxygen, so the action will become slow.

It is impossible for Lin to open a hole in the blood vessel, so that the contents inside will flow out, but the cells in the blood vessel are not moving by themselves, but by the water flow inside, so Lin does not care so much.

Lin ’s devourers have also been updated. They have a vascular structure, but no heart. Instead, they are composed of a muscle cell deep in the mouth and connected to the storage sac of the blood vessel. At this time, the capsule will contract, squeezing the internal food and water into the vascular system, and the cells in the blood vessel will be decomposed to transfer nutrients to the whole body.

The excess water circulates back into the capsule in the blood vessel and is expelled the next time the devourer opens his mouth.

The plan to resurrect the Buckler worm was temporarily put on hold, because Lin couldn't get so many cells to fill the Buckler worm's shell, and because the heart and blood vessels have been consumed a lot, it needs to find more food.

But this cold lasted a long time, although it did n’t affect Lin, but it meant that other cells would n’t appear, so there would be no food. Although the fat cells were enough for Lin to last for a long time, but If you make another thing about the size of an aircraft carrier, it will consume more than 70%. Lin doesn't want to consume so much reserves. What will happen if she encounters danger again?

Maybe it can digest the aircraft carrier itself, and then build a new base in the shell of the buckworm?

No, Lynn doesn't want to depend on other creatures like this. It wants to grow such a hard shell. If it lives in, it will be difficult to evolve a hard skin.

What now?

Going out to find food?

Do you dig it again with a huge digger?

It seems too slow to do that. Lin hopes to make more powerful ice-digging structures, like the buckworm worm digging very quickly ...

By the way ... The Buckler worm didn't dig out the ice with its arthropods, it seemed to smash the ice with the semicircular carapace of the head, but that required huge size and strength.

In this case, only modified aircraft carriers.

Lin ’s aircraft carrier itself is a cylindrical body, which is very suitable for collision, but Lin does not want to use the aircraft carrier itself to collide, but instead forms two huge tentacles on both sides of the aircraft carrier ’s body. Shaped, with a saw-toothed structure, its name is "hammer head", the tentacles are composed of a large number of muscle cells, which can exert a powerful force and break the ice.

Originally, this structure was thought by Lin very early, but because continuous swinging will consume a lot of muscle cells, the energy replenishment time is too long, and the efficiency is not very high, but with the vascular system, Lin can swing her tentacles at the same time Continue to supply energy to muscle cells, the efficiency is much stronger than before.

After the construction was completed, Lin began to activate the aircraft carrier. The aircraft carrier itself had two swimming tentacles, and there were huge water spray holes at the rear end. It could move very quickly. If it was not icing around, the round shield worm It won't hurt it.

After leaving a part of the cells in the buckwheat worm shell, Lin embarked on a journey of crushing ice.

Before the aircraft carrier reached the ice layer, the hammered tentacles slammed against the ice wall. Under the great force, not only a hole was hit on the ice wall, but also numerous cracks appeared around it.

It really works, it feels similar to when the Buckler worm was excavated.

Lin asked the aircraft carrier to continue to wield the hammer, smashing the ice crystals in front of him completely, and smashing out a channel that allowed the aircraft carrier to move.

Then Lin also made the carrier's head hard, so that it could not only hit the ice with a hammer, but also hit itself.

Lin refused to do this before because she was afraid of damaging the vascular system in her body, but now it looks like there is nothing wrong with it, because there is also a vascular system in the hammer tentacles, and it was not injured when he just waved it.

The large eyeballs on the head of the aircraft carrier were degraded by Lynn, and they were changed to form a few small eyeball tentacles on the side of the head of the aircraft carrier to observe.

This time, it is much easier to move forward in the ice.

Should it continue to move down?Lin felt that those wild cells should be hiding in the sand below. It might be very warm there, and the ice could not freeze there.

Thinking, Lin changed to go down and continue to break the ice layer easily. Although the ice layer will have different hardness, it is not a problem under the attack of the hammer and tentacles. It will probably not take long to reach the bottom. The beach.

strange?

After smashing a layer of ice again, an unusual sight appeared in front of Lin's eyes. There was no place on the beach yet, but there was an ice-free area.

This is an ice cave enough to accommodate Lin ’s three aircraft carriers. There is no sign of excavation on the surrounding ice wall. Lin does not know how this was formed. Lin slowly swims into the open space in the ice.

Strange place, why is there such a place?It is impossible for ice to dissolve like this, is it some kind of creature dug out?But did not see that creature.

Lin was wondering the reason for the formation here, and suddenly found that there were some small points moving on the surrounding ice wall.

what is that?

The eyeballs and tentacles on the side of the aircraft carrier could not be seen clearly. Lin dispatched the small devourers in the body of the aircraft carrier. When they swam near the ice wall, they found that the small spots that were moved were some cells. Easy to see.

These small cells are widespread on the ice wall. Lynn doesn't know what they are doing, but in short, the food is right.

Lin didn't think too much, let the devourers begin to hunt them, while Lin let the aircraft carrier release more devourers, ready to clean up these cells.

The devourer quickly swallowed the cells on the ice wall. These cells have no defenses, and they are also very round in shape. They are still very small, but they can do a weird thing to escape the devourer.

They can drill directly into the ice, without relying on any digging method, but directly into it.

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

What a peculiar thing, how did they do it?Lin carefully observed them. From the eyes of the smallest devourer, it could see that the cells seemed to secrete a liquid that could instantly dissolve the ice crystals around the body, so they could enter and exit the ice.

It turns out that this is how the hole was made by them?Then this cell should be called ... 'Ice-dissolving bacteria'.

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

Boom!

At the next moment, Lin Lin ’s giant hammer tentacles slammed onto the ice wall. This time not only smashed the ice wall, but also smashed the ice-melting bacteria hiding inside, and the devourers quickly mixed these with ice chips. The small cells in the swallowed up.

The ice-melting bacteria knew that it was not safe to hide in the ice, so they fled deep together, and Lin immediately smashed the ice layer again, chasing them in the direction of their escape.

Although these ice-dissolving bacteria are said to be able to drill in ice, in fact, the speed is very slow. There is no Lin ’s aircraft carrier to break the ice quickly. Lin can smash a lot of ice-dissolving bacteria from the ice almost every time Zhilin directly asked large devourers to swallow them with ice debris and bite into the powder.

Lin hammered them out of the wall while moving forward, but before Lin had advanced, she suddenly found herself entering the water again, and there was no ice in front.

Entered the ice cave again?No, not right.

Here is the vast waters, Lin has left the frozen area.

what is that?

In front of Lynn, a strange sight appeared.

In the vast waters, it is still empty and empty, but in the sand below, there are many things that Lin has not seen before.

Most of these things are flat long or round in shape, and the surface is covered with striped protrusions. Some of them lie on the sand, and some stand in the sand. Lin looked at it for a while before confirming that it was a creature, because they were almost motionless But when a stream of water passes by, their bodies start to sway, and tentacles extend from the surface of the body, waving in the flowing water.

These organisms should also be a combination of multi-cells, and their number is very rich, almost all over the entire beach. It seems that there is a reason why the round shield worm does not eat single cells. It should be better at eating these multi-cell organisms.

Where do these multicellular organisms come from?Lin has been a single cell that she has met for so long. Since when have other cells appeared in multiple cells?
