Immortality is undoubtedly a rather contemplative topic, not to mention monks, even ordinary people are full of yearning for immortality, and the obsession with immortality can even be said to be the ultimate wish of the Chinese people hidden in the bottom of their hearts.

Therefore, when Fang Shi mentioned this topic, the curiosity of the three of them was immediately aroused, like a wildfire lit on the winter grassland, out of control.

Xia Yuyao is the youngest and the most uncontrollable, coupled with the deep feelings in her heart for Fang Shi, which makes her Fang Shi seem even more presumptuous, at this time, her eyes are as bright as a morning star in the darkness before dawn.

"Uncle, why can't you copy it? If there is a creature that can live forever, from the point of view of modern science, then this situation must be replicated. ”

Fang Shi nodded with a smile: "Actually, I am also very interested in immortality, since the day I joined the ranks of warlocks, I have been interested in the term immortality, you are studying medicine, you should have an understanding of the growth and aging of life, so modern science thinks, why do organisms age?" ”

There are many theories about this, the most mainstream is probably the gene loss theory and the death code theory, the gene loss theory believes that the cells of organisms will gradually lose some gene fragments in the process of continuous self-replication, and as more and more fragments are lost. Organisms will grow old and eventually die. ”

Fang Shi smiled at Xia Yuyao. motioned for Xia Yuyao to continue.

As for the death code theory, it is believed that the code sequence of death is hidden in the genes of living things. Biology is a continuous growth process, and the growth process is genetically controlled, and this growth gene sequence inherently contains the process of aging. ”

Fang Shi nodded and said: "In addition to these two views, there are some other views, such as metabolic slowdown to guide aging, etc., these levels are lower, it is not enough, as for the more alternative, there is another death code." That is to hide a death command in our souls. However, tracing back to the source, it is still the two that you just mentioned that are most in line with the current cognition. ”

Xia Yuyao frowned: "You mean the current cognition?" ”

"Of course, as we get to the bottom of our understanding, there will be further theories, isn't it?"

Xia Yuyao lowered her head and thought about it, and nodded approvingly: "But, what does this have to do with what you said about not being copiable?" If the dragon can really live forever, it must have some kind of specificity in cell replication, and this specificity does not lose gene fragments when the cell replicates itself. ”

"Or maybe the dragon cracked the death code in the genes. As long as we find this evidence in the cells and chromosomes of Jiaolong, then we can try to replicate this pattern of immortality through guò genetic modification and transgenic forms, right? ”

Fang Shi said the second half for Xia Yuyao. Xia Yuyao nodded vigorously, Fang Shi looked at Lou Jingzhong and Xu Liquan with a smile, both of them nodded resolutely in agreement, and the eyes of the three of them all showed a trace of excitement, because Xia Yuyao's statement is very strict logically, and it is theoretically feasible, perhaps, this kind of thing can really be seen in his lifetime, even if he is pessimistic, it should be feasible to effectively delay the aging of human beings.

Fang Shi naturally knew what they were excited about, and he smiled playfully: "Yu Yao, your idea is also the idea of many people, otherwise why would so many people be crazy chasing Jiaolong?" ”

Xia Yuyao pursed her lips: "Actually, aren't you the same?" ”

"Hehe, I'm curious, and at the same time I want to test my conjecture."

"Conjectures about immortality? Isn't everyone trying to verify it? ”

Fang Shi raised his eyebrows proudly, Xu Liquan was a little amused in his heart, only in these small actions, Fang Shi still retained the leap of a young man, not like a great grandmaster at all, of course, if you think that Fang Shi is a very impulsive person, then you are ready to be killed by him.

"It's about immortality, but my guess is different from yours, and you're trying to test the two theories you just said, right? And I have another theory. ”

"New theories?"

Xia Yuyao looked at Fang Shi in surprise, and Fang Shi shook his head slowly: "It's not a new theory, but a very old theory." ”

"Very old theory? What is that? ”

"Double cultivation of life!"

Xia Yuyao frowned, Lou Jingzhong also frowned, Xu Liquan didn't bother to do that, he just had to listen, anyway, he couldn't think of anything in this regard.

Xia Yuyao was very smart, and she quickly connected Fang Shi's words to the discussion just now: "Uncle, you mean to say that aging is not in genes at all, no, no, yes, yes"

Looking at Xia Yuyao's scratching of her ears and cheeks, Fang Shi knew that she was almost a layer of window paper that was not pierced, and she must have felt very uncomfortable in her heart, but he was not in a hurry, just looked at Xia Yuyao, whose cheeks were getting redder and redder.

Lou Jingzhong suddenly slapped his thigh very blindly: "I understand, double cultivation of life!" You mean that Genshin is closely related to genes? ”

Xia Yuyao's eyes lit up: "Yes, that's it, do you think the Yuan Shen is the key!" ”

Fang Shi smiled and nodded: "Yes, that's what it means." ”

Xia Yuyao thought for a while and said, "This idea is also very reasonable, but is there anything to prove it?" At least there is some evidence for the theory of genes, and can you find evidence for this theory? ”

Fang Shi looked at Lou Jingzhong with a smile, and saw that he frowned again, obviously, he was stopped by Xia Yuyao's question again, in fact, this theory of dual cultivation of life has been put forward for more than 2,000 years, but no one can put forward effective proof, of course, there are many exercises created according to the theory of dual cultivation of life, and it does seem to have the effect of prolonging life, but this does not seem to prove that this theory is the truth of the theory of longevity.

In fact, there are not only the dual cultivation schools of life in the cultivation methods of Xuanmen, but also the cultivation and heart cultivation schools of Confucianism and Buddhism, as well as the Waidan school of Taoism, as for the evil ways and tricks, it is even more varied, so just holding high the banner of double cultivation of life and life cannot convince everyone, even if these people in front of them have a high degree of trust in Fang Shi, Fang Shi may not be able to convince them with this.

"Evidence, you can say yes or no, I'll talk about my theory first, and then you can see if you can find evidence."

Xia Yuyao nodded like a chicken pecking rice, her confidence in Fang Shi was actually very full, not so much that she was questioning, it was better to say that she was expecting Fang Shi to shock everyone again, from her bright eyes, Fang Shi could see a lot of content.

"You say, what kind of curve does a life, especially an advanced life, go through from birth to aging?"

"Parabola!" Xia Yuyao replied without thinking about it.

"That's right, then there is a problem with your theory of gene fragment loss, since cell self-replication is a process of continuous loss, how can there be a first half of the parabola? There should only be a slash from high to low. ”

Xia Yuyao blinked: "What about the genetic code theory?" ”

"The genetic code? Who decides? Who wrote this password? Is there really a God? ”

"Isn't this naturally evolved?"

Fang Shi smiled: "You are arguing, okay, let's not talk about plants and lower animals, now add the theory of dual cultivation of life, that is, life is not simply an attribute of living beings, but also an attribute of soul." Take human beings as an example, the soul of the newborn baby is very weak, but as time passes, their soul grows, so the body also begins to grow with the growth of the soul, and when it reaches adulthood, the human soul has a bottleneck, and even begins to decline, which we warlocks can better understand, so with the decline of the soul, the body also begins to decline, these two factors are complementary to each other and affect each other, the ascending stage is a virtuous circle, and the descending stage is a vicious cycle, so why life will age and die, it will soon be obvious. ”

"According to your theory, uncle, if the soul can continue to grow, people will live forever?"

"No, you don't need to grow constantly, you just need to grow to a certain level to be immortal."

"What does this mean?"

"It's very simple, Jiaolong's existence is enough to prove it."

"Jiaolong?" Xia Yuyao looked at Fang Shi in confusion.

At this time, Xu Liquan, who had not spoken, suddenly interjected: "Master Fang means that Jiaolong's life form is simpler than that of humans, so when Jiaolong's soul is strong enough to a certain extent, it is enough to keep this life form from entering a vicious circle, right?" ”

"That's right, the soul strength of the dragon, no, the strength of the primordial god is probably equivalent to the strength of a super-first-class warlock, it is obvious that super-first-class warlocks will not live for a long time, although their lifespan is much longer than that of ordinary people, but the same strength of the primordial god has allowed the dragon to live for thousands of years."

Fang Shi's words were like a key, opening a closed door for the three people present, and behind this door, there was a faint hidden treasure of the most dazzling and fascinating, that is, immortality.

Xia Yuyao's eyes were full of admiration and looked at Fang Shi, she felt that Fang Shi's theory was very close to the truth, no, maybe that was the truth, anyway, she herself had no way to find a flaw from Fang Shi's theory that was enough to overturn this theory.

Lou Jingzhong pondered for a long time, and had to admit that Fang Shi excavated the theory of double cultivation of life almost perfectly, in fact, the theory of double cultivation of life is still very marketable in Xuanmen, if Fang Shi's theory is officially launched, it will definitely gain a large number of supporters, and Lou Jingzhong has thought of a way for Fang Shi to prove his right to the world, that is, to raise a dragon out!

However, he just said that it can't be copied?! That's weird!

"However, Master Fang, there is a fatal point in your theory."

"What?" Fang Shi looked at Xu Liquan with a smile.

"Why is there a bottleneck in the growth of the original god? According to you, the growth of the original god is also a parabola, so who stipulates this? (To be continued......)
