Chen Yulan's thinking is basically correct, but she can only think of this step, in fact, all the predecessors' research is also stuck here, guessing whether the bloodline determines the Yuanshen, or the Yuanshen decides that the bloodline only needs to move his head, but to confirm his guess, it is difficult to start.

Or maybe the two are one and the same as each other, but it is precisely because it is difficult to confirm that when Chen Yulan guessed the purpose of Xu Xingkong's experiment, an impulse surged in his heart, which was the persistence of pursuing the truth.

Just when Chen Yulan's heart was as uncomfortable as a white cat scratching, Wu Dingguo turned his head to look in the direction of the door:

"This kid is here. ”

Before the words fell, Xu Xingkong drilled out of the wall not far from the gate, of course, this is not that Xu Xingkong has mastered the legendary technique of piercing the wall, but that it was originally a hidden entrance, but in the eyes of uninformed people, this entrance is just a wall.

Seeing this, Wu Dingguo got up and said with a smile:

"Sneaky, aren't you hiding from those old guys?"

Xu Xingkong glanced at the children who were concentrating on practicing, shrugged his shoulders and said:

"Do my seniors think it's superfluous for me to be so careful?"

Wu Dingguo pursed his lips, too lazy to grind his teeth with Xu Xingkong, and waved his hand a little boringly:

"Without further ado, since you're here, what are we going to do next?"

Xu Xingkong had already walked in front of the two of them, and did not answer Wu Dingguo's question, but saluted Chen Yulan, who was smiling:

"It's been a long time. ”

Chen Yulan returned the salute and shook her head and smiled:

"Elder Xu is too polite, I can't ask for it, why bother to say it, in fact, I am also looking forward to it. ”

Xu Xingkong nodded with a smile:

"What's next..."

Xu Xingkong did not say the answer directly, but turned his gaze to the children who were practicing, Wu Dingguo twitched the corner of his mouth and said angrily:

"I can't complain about this, who told you that Yushan Yuzhai's exercises are not the same way as me, otherwise why don't I transfer some disciples from the sect over?"

Xu Xingkong snorted, shook his head slightly sarcastically and smiled:

"No need, as the predecessor said, I am not the same path as the disciples of your sect, and if you transfer the disciples from the sect over, it will not help my research at all. ”

Chen Yulan pursed her lips and smiled silently, this old and young seem to like to communicate in this way, of course, this has nothing to do with Xu Xingkong's disrespect for the elderly, and it has nothing to do with Wu Dingguo's love for the younger generation, in fact, the strength of these two people is roughly equal, they are really equal people, but because of the difference in age and generation, this kind of conversation that was originally reasonable has become a little weird.

However, judging from Xu Xingkong's answer just now, his unwilling to suffer is more in line with his age.

Wu Dingguo glanced at Xu Xingkong:

"When I didn't say it. ”

Xu Xingkong smiled, looked at the children and asked:

"When will they be able to do it?"

Wu Dingguo pondered for a moment and replied:

"You can't generalize, the ones with the best qualifications tomorrow should be fine, what else... It's okay in about three days. ”

Xu Xing thought for a while and said:

"Then wait another three days, but in these three days, we still have to test more children who have not cultivated to obtain more data. ”

Wu Dingguo didn't say anything more when he heard this, just nodded in agreement, and Chen Yulan's eyes lit up and took the opportunity to ask:

"Elder Xu, I have a question that I don't know whether to ask or not. ”

Xu Xingkong said with a smile:

"What questions does Daochang Chen have?"

"That's right, our experiment is a bloodline optimization study, right? I have communicated with Xue Xun about the test data and modeling results I have obtained before, but Xue Xun told me that the purpose of the experiment is to verify the theory of the human magic circle, which..."

Xu Xingkong first glanced at Wu Dingguo, who seemed to be smiling, and then replied unhurriedly:

"What Elder Wei said is right, in fact, this is a two-in-one thing. ”

Chen Yulan frowned and said:

"Two and one?"

"Yes, two and one. Elder Wei and I were previously researching the human body circle theory, and although we thought that the system constructed by this theory had been self-consistent, it still lacked irrefutable empirical evidence, so we planned to change the direction and lower the height of the original research and start from the most basic facts. ”

Chen Yulan quickly thought about Xu Xingkong's words, and then looked at Xu Xingkong with uncertainty:

"What does Elder Xu mean is that the theory of the human body formation has an inseparable relationship with the bloodline?"

Xu Xingkong nodded:

"Yes, Daochang Chen, senior martial arts, I don't know if the two of you have ever thought about why there is a difference in the qualifications of children? Is this difference from bloodline inheritance, or from the qualifications of the Yuan Shen itself, or because of the differences in acquired growth?"

Wu Dingguo scratched his head, and said with a smile that he couldn't answer this question, while Chen Yulan carefully considered it for a while before replying with some hesitation:

"I think it may also be the result of the interaction of several factors, but the genetic factor should be minimal, and in fact, the qualifications of the descendants of the cultivators are not necessarily better than the descendants of ordinary people. ”

"What about the demon clan? Isn't there a saying that the human race is actually a member of the demon race?"

"It's... Maybe this is the special attribute of the human race?"

Chen Yulan's statement is not surprising, and it is a rather marketable argument.

Xu Xingkong nodded noncommittally and said:

"It's possible, but I have another opinion, I think that the reason why the Terrans lack obvious bloodline inheritance attributes is due to too much hybridization. ”

Chen Yulan was stunned for a moment, then her eyes lit up suddenly, and she asked in a somewhat hurried tone:

"Please continue. ”

"This conclusion is actually not difficult to confirm, in fact, the descendants of different races of the demon race have generally degraded in strength, and the probability of better offspring is extremely low, according to this result of continued hybridization, the final result is likely to be the emergence of another human race, perhaps, this is how the human race came. ”

Chen Yulan thought for a moment and retorted:

"I admit it's a possibility, but it's just a possibility, it doesn't prove anything, and we can't verify your suspicions. ”

Xu Xingkong nodded:

"Yes, so we also found another corroboration, that is, the legend of the ancestor of the human race, according to the legend, the human race originally had nine tribes, and then these nine tribes merged with each other and multiplied, the population of the human race gradually increased, and the territory gradually expanded, so there was the battle of the Central Plains, the dispute between Yanhuang and Chiyou. These are all well-known legends and histories, but please note that there is a fact hidden under this main line of Terran development, that is, with the expansion of the population and territory of the Terran, the strength of the elite masters of the Terran is degrading, doesn't this just confirm our suspicion?"

Chen Yulan raised her eyebrows, thought for a while, and said:

"Well, even if your speculation is very reasonable, we still need empirical evidence, not just speculation, besides, there are many explanations for the degradation of the strength of the Terran elite, and they all sound very reasonable. ”

Xu Xingkong smiled slightly:

"Well, that's why we need to do this experiment, I want to see if there are obvious classification characteristics of human bloodlines through this experiment, of course, what I want to figure out is not the superficial characteristics and attributes, if that's all, there is no need for martial seniors to take action, there are many ways to identify characteristics and attributes. ”

Chen Yulan asked suspiciously:

"Do you want to say 'recessive gene'? This can be seen by stimulating the gangqi?"

Xu Xingkong was silent for a moment before he said solemnly:

"You two, what I'm going to say now is very important, and I won't admit to saying it when I leave this door. ”

Wu Dingguo and Chen Yulan quickly exchanged a look, and at the same time nodded to Xu Xingkong, Xu Xingkong continued:

"First of all, in the body of the half-demon, that is, Zhen'er, I found the phenomenon of self-repair of genes, in order to continue life, Zhen'er's genes automatically constructed a structure, although this structure is very simple, but it allowed Zhen'er to survive, this structure suppressed the dominant gene of the Ying family's bloodline, and forcibly used the genes of the human race to make up for it, but this supplement was obviously not strong enough, which eventually led to the defects of Zhen'er's body. ”

Chen Yulan asked thoughtfully:

"What does Elder Xu actually want to say?"

"What I want to say is that in order to survive, intelligent beings will choose to reduce the frequency to survive, so there may be such a mechanism in our genes, which is the root of our weaker and weaker, even if there are occasionally excellent individuals, but because of re-hybridization, excellent genes cannot be passed on. ”

Chen Yulan's face changed, what Xu Xingkong said is actually very likely, this kind of deterioration phenomenon is common in reality, such as excellent hybrid plants can not be retained, for example, excellent hybrid animals cannot reproduce, the most obvious is undoubtedly the half-demon, the half-demon will never give birth to half-demon offspring.

"But both husband and wife are descendants of excellent cultivators..."

"This is a false proposition at all, the so-called excellent cultivators may not be a category at all, I am talking about genetic elements. If the two strong people are not of the same ancestral bloodline, the result is still hybrid, and the proportion of offspring deterioration is very high, in fact, I can use this to disprove it, both of them should know that if the parents are cultivators, there may also be descendants with extremely high qualifications, although there are the results of hybrid mutation, and it is not that the ancestral bloodline without parents is exactly the same, and the result can give birth to excellent offspring, such as... Consanguineous marriage. ”

"But it has been proven that the offspring of close relatives will gradually deteriorate!"

Although Chen Yulan immediately opened his mouth to refute, he was a little shaken in his heart, and he also knew why Xu Xingkong said the previous sentence, if this speculation spread, it might really have bad consequences.

Xu Xingkong smiled weirdly and said:

"Then it depends on how strong the bloodline is, at least the inbreeding of the demon clan will not deteriorate, at least it will not deteriorate quickly. ”

Chen Yulan and Wu Dingguo were silent, both of them knew very well what Xu Xingkong's guess meant if it was true.

If the bloodline of the human race is really constantly deteriorating, but the demon race does not have this problem, at least if this problem is not serious, it means that the failure of the human race is an unchangeable fate.
