4.6 Billion Year Symphony of Evolution

Lin found that the biggest creature ever was so spectacular when it fell down. The whole giant tree made a creaking noise at first, because the branches at the top of the home tree extended into the rock layer at the top of the cave. When it fell, huge cracks suddenly cracked and spread on the top of the cave, and countless rocks were pulled and collapsed by the fallen trees. Finally, as the structure of the tree couldn't withstand the pressure of the body weight and caused the crack, the whole tree collapsed .

At the moment when the tree crashed to the ground, the whole underground world made a thunderous loud noise, and under this tree, it was the location of the two purgatory worms.

The speed of the Purgatory worms is quite slow. They can't even retract to the ground quickly. In the case of evasion, they can only watch the collapsed home tree fall on their heads.

Although they are the largest animals, they were almost unbearable under the impact of a giant wood of more than 300 meters. The solid carapace of the whole body was crushed and squashed instantly. Lynn only heard a sound of crumbling. There was also a strong scream, and the two huge creatures were crushed to pieces.

A worm's head was partially exposed outside the collapsed home tree. Its internal organs sprayed a distance of more than 100 meters, which made Lin have to lament the horrible weight of the home tree ...

I haven't tested how big the tonnage of the home tree is, but this time, the war is completely over.

But there is still a problem in it, a very important one.

This was not done by Lin.

Yes, the collapse of the home tree has nothing to do with Lin. In any case, Lin will not risk the collapse of the home tree by risking the collapse of the underground world, because the home tree is probably the 'support column' here.

Even if you drill a hole in it, you will be very careful not to affect the main structure of the tree, and it is impossible to deliberately knock it down.

Was that done by the Inca Swarm?It's also unlikely, why are they smashing themselves?And Lin found that the structure of the Inca worm swarm was very careful. They would not knock down a tree anyway. Although they burned their home trees, they certainly knew that there would be no threat ...

So, since it is not the Inca Swarm, how did the home tree collapse?

This is what Lin will study next. This is really strange. The whole house tree is very strong. How can it be disconnected from the middle?

Lin let the last troops of the army come out. These are the collectors used to clean the battlefield. Lin originally intended to use them to recover all the corpses on the battlefield after the war. At the same time, he studied some powerful Inca worm swarms. Now.

A large number of collectors appeared from the forest on the north. Because it felt that the number was not enough, Lin asked the mobile base to start producing more collectors. At the same time, the collectors also went to the battlefield to devour all the edible things, including those charred creatures. .

The ground-splitters are still in a coma, and it seems that the mucus acid effect is very good, but why can the Inca worm swarm of hell create a gas that can make mucus acid deteriorate?

Lin did n’t think much at the time, but now she thought about it for half a second. This is a very simple problem, because the mucus acid is blocked in the blowhole of the groundbreaker, so there must be some infiltration and the smell of the groundbreaker. The organs are absorbed, and then even if the ground-splitters are in a coma, their brains may run at low power, so that they can send acid information to the purgatory worm. After all, the Inca worm swarms can be connected to each other.

The purgatory worm received the information and began to release gas after learning about the acid, in an attempt to help the ripper break away.

Although Lin is using this mucus acid for the first time, the actual composition is a combination of the usual dissolution liquid and some mucus. Many common organisms can secrete similar substances. The Inca swarm is familiar with it. Not surprising.

Lin temporarily doesn't deal with the ground-breakers first, and keeps them asleep. The collector first solves the other corpses, as well as the collapsed tree and the creatures below.

The collector is very small and can be drilled under the collapsed giant wood. Inside, the collector finds that the purgatory worms are almost completely squashed, and there are scattered blood and pieces of carapace everywhere, which is very troublesome to study.

Although the outer shell of the purgatory worm may be very good at resisting deep pressure, but it is easily crushed by the home tree. Lin has also studied this situation.

This situation is like a fish that can resist several thousand kilometers of water pressure in the deep sea, but it can be easily knocked down by any hard object.

Lin called it "complete pressure" and "incomplete pressure", and it felt interesting.

In short, the collector began to break down some of the blood and organs that engulfed the worms under the tree, but it is difficult to know the structure of the body just by some cells.

At the same time, Lin also asked some collectors to climb up the tree to study the reason why the tree broke and collapsed.

After a period of research, Lin found that there were many holes and cracks in the overall wood structure of the home tree. These damages were almost all over the entire tree, but there were particularly many parts between 20 and 30 meters high. In addition, this home tree was hit by sand blasting sand balls during the war, blown up by the explosive armor, hit by the jaws with the jaws, and burned by the purgatory worm. Under various influences, it only last It broke and collapsed.

Although the war between Helin and the Inca Swarm had a great impact, in the final analysis, there have been countless damages.

What caused this damage?

That's something Lynn is familiar with ... fungi.

The whole home tree is covered with fungi. I do n’t know when they started to grow, but it has damaged the wooden structure of the home tree so much that the fungus has filled it with holes and cracks, making The whole tree is close to an extremely weak state.

Home tree ... Will it be affected by fungi?

Lin remembered that headworms once said that when they saw the home tree on land: "The home tree will not collapse and collapse. The trunk composition is quite strong. Only the fungus will destroy the tree structure. There is no fungus here."

Although the home tree on the land is fine, the fungus has invaded this underground world ...

'Click ...'

At this time, a violent noise suddenly sounded, and a large crack appeared on the top of the cave that was originally supported by the home tree. These cracks were still spreading and expanding, and a large number of luminescent creatures fell.

Sure enough, the home tree has a crucial influence on the support of this cave.

The crack stopped when it spread to a certain range, but there is no guarantee whether it will continue to spread, and the structure inside may be damaged.

Fungus ... If it invades this underground world, it is likely to destroy the whole underground. Is this brought by Lynn's troops?

Lin immediately asked the troops in the base of the rock to study the surrounding home trees. Lin did not find any fungi at all. In fact, these fungi are relatively hidden. Even if the home trees are dug out, the structure inside is not decomposed unintentionally.

Found!Lin also found fungi in the trees in her homeland on the other side of the rock, but the content was very small, there was no threat, and there was no time to deal with it.

But why is this home tree on this side already covered with fungus and is so fragile?

Is it related to the time of infection?No, it should be different from immune cells.

Lin found that the home tree on the other side of the rocky land has a special kind of cell that can resist the spread of fungi, but this one has no immune cells, so it caused the fungus to spread?

Why is this happening?

Perhaps there is only one reason. The home trees on both sides are too far apart. It has been too long for the two sides to lose contact and reproduce the relationship. The immune system in the body has started to be slightly different.

It is a mystery how long the lifespans of home trees are, but there is indeed a large gap between them. Lynn has done some research on them, and even the internal structure of some trees is different.

When it comes to reproduction, Lin has never seen home tree reproduction, nor have they seen any seeds. They are located in various places in the underground world as if they were fixed. Lin does not know how they spread and spread the population.

It is necessary to let the immunized home trees reproduce to produce offspring that are not afraid of fungi. Of course, Lin has also tried to transplant immune cells on the land, but it usually has no effect, even if it is the same species The immune cells in the body will also kill other immune cells from the same kind, which is quite troublesome,

If the transplanter and the transplanted person were split from one organism, there would be almost no rejection, but it is obviously unlikely that the home tree is so large between the individuals.

By the way, the breeding of home trees may have something to do with the Inca swarm.

The Inca Swarm should know how the home tree reproduces ... that is to say ...

Go to the Inca Swarm.

The current situation of the Inca Swarm can be said to be quite strange. After the two purgatory worms were crushed to death, a large number of troops in their territory ran out of their home trees. The war between the Inca Swarm and Lynn did not use all the troops, but They do not want to continue to fight now, but almost every unit has built the rock nest before it. They shred the rock, mix it with spider silk and mucus, and put them together to form a tower or ball, and get it out on the surface. Many openings serve as passages. What do they mean by getting these things?

Either way, Lin had to go and see if they had anything to do with the propagation of their home trees. Lin really did n’t want to win until she discovered that the place was about to collapse.

At the same time, Lin has also conducted some research on the crushed purgatory worm. Because the head of the purgatory worm is crushed because of the crushing, it is difficult for Lin to figure out its brain structure. He can only make some calculations and guesses, but the collector We can drill into another part of the purgatory worm buried under the ground for detailed research.

How many secrets will this wonderful giant creature have?
