Three-Body Problem: The Star Omnic Fleet, Crush the Three-Body Problem

"From what we have observed, the metal and stone blocks are ordinary metal and stone blocks, and they have no structure at all that silicon-based life or mechanical life should have.

However, in those metal and stone corpses, we also found fungal hyphae that had previously been found in the organism.

So after repeated experiments, we created a variety of media to try to grow this fungus, and finally found that only two media were suitable for cultivating this fungus.

One is a living organism and the other is a stone. "

Number One pointed to the two petri dishes and explained to Ye Xingyun.

"Why is this happening? Aren't these two scenarios too extreme? "

Ye Xingyun was a little surprised.

"According to our modeling, this fungus was born as early as the beginning of primitive life, and when single-celled consumers appeared, they continued to hide underground in order to avoid primitive consumers, and became a special fungal producer that could carry out reactions such as nitrification instead of sunlight.

It is also because of this situation that they developed more and more downward in the next few hundred million years of evolution, going deeper and deeper into the ground.

Because in essence, the energy on the surface of the earth comes directly or indirectly from the sun, and the energy below comes directly or indirectly from the center of the earth, the further down you go, the more energy you get.

In order to avoid some hard minerals and high-temperature danger zones during the mycelium journey, they evolved a hyphal information exchange pattern similar to a neural response.

Speaking of which, Commander, you already know what these fungi are by now, right? "

Number One raised his head and looked at Ye Xingyun.

"You're saying that these mycelium are the bodies of those guys, and that the metal stones are just derivatives formed to protect themselves from shellfish shells? It seems that they look different, but in fact they are all a kind of creature?

So, they're terrestrial creatures, but we're on the surface, they're coming from underground! So why can they parasitize living beings? "

Ye Xingyun's eyes moved slightly, and he said the guess in his heart.

"First of all, it's completely true that they are the undead.

Secondly, because the mycelium is not as powerful as the muscular structure, even in hundreds of millions of years, they travel underground to a depth of 100 meters at most.

And because of geological reasons, their development space is limited to the area where they were originally born, which is not very large.

So, in the process of expanding the scope of their existence, by chance for hundreds of millions of years, they evolved parasitic surface organisms, and directly incarnated their nervous system with themselves, so as to be able to control the host to take them farther away, and in the process, their mycelium will greatly enhance the host's self-healing ability.

In other words, after being parasitized by them, the host becomes a zombie under their control and extremely strong. "

Machine One's voice was calm, stating the results of the study.

"So, the ability they give creatures infinite self-healing and mutation comes from here?"

Ye Xingyun's eyes moved, and he asked again.

"Not exactly, this comes from the biotechnology that they evolved.

After all, as fungi, they only have hyphae and live underground with very low energy density. They wanted to differentiate into a memory structure like the brain, without the support of an energy base, so they evolved an innate ability to study biotechnology.

That is to rewrite the gene, the knowledge obtained is directly engraved on the gene, and it can be modified at any time, and because at that time, they did not have the concept of self, so the gene engraved by learning knowledge from the outside world can communicate directly through the link of each other's hyphae. "

As he spoke, No. 1 projected a model in Ye Xingyun's mind, simulating the appearance of the undead carving genes.

"So, it's no wonder that we have survived such a long time."

Rao is Ye Xingyun couldn't help but feel shocked.

"That's not all, but then they learned to make a protective shell for themselves out of minerals. And in the process of exploring underground, he successfully domesticated the metal, and can use an alloy that is tougher than stone to create a protective shell.

Metals are rarer than stones underground, so in this case, the respective colonies that were originally differentiated due to the untimely genetic exchange of mycelium finally naturally had the concept of 'self', hundreds of millions of years earlier than human beings, forming the prototype of civilized society.

And according to the records we read their genetic memories, many of the previous civilizations on the Blue Star were destroyed by them because they felt threatened from the surface, and even many gods of mankind in the Age of Ignorance were the prototypes of them. "

No. 1 continued to speak, answering Ye Xingyun's last question.
