Tang Shuxing shook his head: "I really don't understand biology, and I can't have so much time to study." Speaking of this, Tang Shuxing thought of Zhan Tianya again, remembered Gu Yan's explanation to himself before, and subconsciously asked, "Gu Yan, did you learn this knowledge at the earliest?" ”

Gu Yan nodded: "I have six bachelor's degrees, four master's degrees, and two doctorates, I think, it's because I'm too flamboyant, that's why I'm targeted." ”

Tang Shuxing gasped: "It turns out that you are a genius, yes, I misjudged you, it's good that a person like you can shoot, I can't ask you to do anything else." ”

Gu Yan shook his head: "I still have to learn, the boss said, I can learn as much as I can if I have time, I have learned enough theoretical knowledge, but I still need to follow you for practice." ”

Tang Shuxing nodded: "Okay, you still continue to talk about the secret of the corpse." ”

Gu Yan nodded and looked at the other culture tanks: "The lifespan of an organism is determined by the NDA sequence called telomeres in the chromosome, because every time a cell divides, it will lead to a shortening of this fragment, that is to say, the more times a cell divides, the more its telomeres are worn, and the shorter the life span of the same cell. In order to move forward with the carrier, but each run-in of the engine will damage itself, and if it is kept running for a long time, the engine itself will be damaged due to excessive wear, which is the same ......"

Gu Yan said. Getting up, he grabbed the kettle and took a sip, watching the embryo inside grow larger again, he approached again, looked at it for a while, and said, "Where did you just go?" Oh yes, so the cell stops dividing within a certain period of time, and the life span of the cell is up, and the life span of the person is basically coming to an end, which can be explained in this way. But there is one cell that does not. And guess what? This is a problem that human beings have not overcome so far, even in the past seven years, Shangdu's medical level has made rapid progress, but this problem has still not been overcome. ”

Tang Shuxing pondered and shook his head: "I don't know." ”

"Cancer cells!" Gu Yan said with a smile. "Cancer cells have the function of repairing telomeres. And there is no limit to the number of splits. Therefore, cancer cells can continue to survive after the loss of human function! ”

Tang Shuxing was surprised: "You mean, the corpse can become like that, and can have an amazing ability to recover. Is it because of cancer cells? ”

"That's pretty much it, but it's not all." Gu Yan explained in detail, "There is a substance called cyclic psychic acid adenosine on the cell membrane of every cell in the human body, which can make cancer cells become healthy cells, but in the same way, there is also a substance called CEA on the surface of cancer cells, called tumor antigen, which can generate corresponding antibodies to prevent the growth and development of cancer cells, so these are very contradictory, it is a problem that has not been overcome, under the right conditions, cancer cells can multiply indefinitely, as I said before, cancer cells do not. However, in our study of necrogeners, we found that these people do not have cyclic adenosine in their bodies, the surface of the cell membrane seems to have been artificially removed, and there is no CEA in the cancer cells in the body, which is very scary. ”

Tang Shuxing probably understood what Gu Yan meant, and asked, "Why is it terrible?" Is it because the problem of cancer cells being unable to kill and completely inhibiting them has not been overcome, has anyone found a way to eliminate cyclic guidic acid adenosine and CEA? ”

Gu Yan nodded vigorously: "That's right, that's what I mean, this is something that modern science and technology can never achieve, if it can be achieved, human beings can already overcome the problem of cancer in the opposite direction and be completely cured, even if it is terminal cancer." ”

Tang Shuxing looked at his body: "In other words, my body is full of cancer cells now!?" ”

"No, it's a cancer cell mutation, which we call the source cell, the source of the source." Gu Yan pointed to the embryo in the culture tank and said, "I think it's that kind of thing in it." ”

At this time, the two saw that the cell began to grow twice as much, and the speed was faster than before, and the two involuntarily took a step back, looking at the thing, as if it was 1 to 2, 2 to 4, 4 to 8, 8 to 16, this speed, it grew at a double speed, and soon there was a baby whose whole body, including the head, was transparent, and then the baby continued to change, and became a dog, and the dog became a monkey, and the monkey became a pig. In this way, the appearance of many animals is changing, and at the same time, it is also improving some things in its body.

Tang Shuxing and Gu Yan continued to retreat, retreating several meters away, watching the things inside get bigger and bigger, and finally turned into a person, but the guy had two pointed ears on his head, pointed nails, and a tail behind him, just like a demon in Western mythology.

"I'll go to your uncle's, can this be?" Tang Shuxing stepped forward and looked at the monster inside, at this time the monster's eyelids trembled slightly, and then suddenly opened his eyes, and turned his body to look at Tang Shuxing, the moment Tang Shuxing and that thing looked at each other, there was suddenly a particularly strange feeling - that thing has no interior, in other words, it has no soul, just a single body.

"Eyes ......" Gu Yan also felt the same way, he trembled all over, and took a deep breath, "How can there be such a thing?" ”

Just when the two of them were surprised, the thing suddenly began to swell, and its head began to grow larger, like a balloon, and then its face cracked, and then it exploded directly.

Tang Shuxing and Gu Yan subconsciously raised their arms to block it, but the monster's body just exploded, and all the flesh and other objects were splashed on the cultivation tank, floating in the unknown liquid in it, and then they were all sucked in by a channel opened at the lower end, and in the end, only the cell embryo they saw was left.

"Look!" Gu Yan pointed to the four cultivation tanks around him at this time, and found that the flesh and blood and other things left by the monster after the explosion had all entered the other four cultivation tanks, and they were re-aggregated and mutated.

Tang Shuxing looked at Gu Yan and asked, "Can you explain?" ”

Gu Yan looked around and said, "There is no information, there is nothing, what explanation will I take." ”

Tang Shuxing looked at the passage: "Forget it, let's move on, by the way, we should put on our clothes, the two of us look too stupid." ”

Tang Shuxing and Gu Yan put on their clothes a few times, took the dragon lin blade, and walked towards the passage with the yin bee in hand.

Entering the passage, the two looked at the cylindrical passage, and found that the top and bottom were transparent, and the floor under their feet was like a small wooden board in the middle of a transparent pipe, and at the same time, because of the water flow outside the passage, the two were a little dizzy, so they had to speed up their pace and walk out of the passage, to the next room, and as soon as they entered the next room, the two immediately froze as if they had been pointed-this is simply a biological exhibition hall!

"Biology Gallery, right?" Tang Shuxing walked forward with his sword, looking at the left and right sides, one by one neatly arranged cultivation troughs, and various strange creatures were placed in each cultivation trough.

Gu Yan shook his head as he walked: "This should be called the Monster Exhibition Hall, almost none of them are human, as long as they are close to the appearance of people, there is everything." ”

Tang Shuxing looked at the monster on the left that looked like a human and a bear and said, "This should be an alien race, right?" I've seen it, bears. ”

Gu Yan nodded and looked at the one on the right: "This is a werewolf, and the hair on the body surface is actually golden, so beautiful, and the face doesn't look so hideous." ”

"I remember mentioning from the mouth of that bracelet that in order to adapt to the world after the mass extinction, in order to adapt to their apocalypse, and for the sake of war, the creation of the zào corpse and the demonizer, I think, maybe these things are all real products created before the creation of the zào demon and the corpse." Tang Shuxing looked at it as he walked, "Even if this cave can simulate the environment, it is impossible to simulate the environment of every region on the earth, so it is also necessary to release these things back into the wild, observe whether they can survive, and see what they lack in the harsh environment, so that they can be replenished in the later stage." ”

Gu Yan looked to the other side and saw something like a mermaid: "Now I understand, how did those monsters seen on the earth come about, all the alien races were created by ancient humans, and I am now too curious about what the earth was like hundreds of millions of years ago." ”

Tang Shuxing glanced at Gu Yan and said, "Maybe the world is more technologically advanced and civilized than our current world, but in the end, we are also facing the same thing as us, that is, the end of the world, natural disasters, and continuous self-destruction." Do you know why ancient humans fought in the first place? ”

Gu Yan stopped and looked at Tang Shuxing and shook his head.

"Too peaceful." Tang Shuxing smiled bitterly, "Maybe whether it is ancient humans or us, in fact, we all have killing genes in our bones, so we can't live a peaceful life, we can only continue to look for enemies, to defeat enemies, and only then can we discover the value of self-existence." ”

Gu Yan nodded: "Actually, this can be understood, just like a person who has everything, he loses his goal and has no motivation to move forward." ”

"Yes, people yearn for a better world, and think that it would be nice if there was no more death in a world, but death is only another beginning, if everyone lives forever, then no new life will be born, and then this group of people will fall into confusion, do nothing, and finally war." Tang Shuxing looked ahead, and at a glance, this corridor was at least a hundred meters long, "We have been walking towards the front, and I am now more and more curious about what else is at this end." ”

Gu Yan nodded: "This place is running as before, it seems that there may be other people stationed there?" ”

"Even if there is, it is with another life form, after all, after hundreds of millions of years, there is nothing that can last forever." Tang Shuxing strode forward, "I just hope that this kind of thing will not regard us as enemies and attack us." ”

Gu Yan turned his head to look at those cultivation troughs and said, "I hope that the things in here are not all alive, if they are released, the consequences will be unimaginable......" (to be continued......
