Great Xia died, this incident made Feng Xue a little surprised, how could Great Xia die?

But when he read the history books carefully, he suddenly realized that this reincarnation was more than 500 years after his previous life.

After he died, the thirteen disciples developed according to his will, medicine, science, engineering and agriculture were the obvious learning, the nine disciples walked the world, spread the knowledge left by Feng Xue, the military, business and politics were hidden learning, the four disciples were hidden in the dark, Yunwen came forward to do business, obtained resources, Ren Shan and Ren Hai secretly cultivated private troops, opened up territory in the wilderness, trained soldiers and cultivated talents, and Yin Lin borrowed the identity of Xu Gong's disciple to enter the officialdom, constantly improve his status, obtain titles, establish a family, and pass on what he has learned to future generations, so that the inheritance is endless.

After three hundred cultivations in this way, the Shen family, the Ye family, and the Chen family have become well-known medical families in the world, and have cultivated countless famous doctors for the entire human race.

Zhang and You studied science (the science of mathematics and physics, which has nothing to do with Zhu Cheng), and made friends with Xue and Fang for generations, integrating science and engineering, and constantly perfecting the inventions that had not yet had soil in the manuscripts left by Feng Xue, and constantly bringing forth the new.

Qi Feng and Dong Sheng put all their energy into the field, and the two families, including their disciples, have been working hard for hybrid rice for generations, and to this day, they have increased the grain production of the human race several times.

And in this prosperous era that should be the great prosperity of the human race, Daxia began to decline from prosperity, Xia Wei ascended to the throne, and committed the act of a tyrant, and at this time, the Yin family, who had been subdued for more than 300 years, finally seized the opportunity, Yin Lin's descendants Yin Shang raised troops to attack Xia, the Yun family provided grain and grass logistics, and the Ren family army that had been cultivated for hundreds of years also had a place to use. The ancestor of the Ren family is also a disciple of Xu Gong, and Li Sanke finally appeared in front of the world.

At this point, the nine sages of Xumen became the thirteen sages of Xumen, and Yin Shang took Shang as the national name and established the current Dashang, which has been more than 100 years ago.

As for the whereabouts of those thirteen disciples, there was no record in the history books, but Feng Xue felt that since they had learned the secret technique of qi and blood left by him, it was very likely that they were still alive now.

Of course, no one knows how long the Qi and Blood Secret Technique can prolong his life, after all, Fang Lin has only extended his life for two hundred years, and now that five hundred years have passed, who knows if there is an upper limit to that secret technique?

Shaking her head and not thinking about it anymore, Feng Xue turned her attention back to the Ye family, this Ye family is not the descendant of Ye Bai's lineage, but a side line left in the Xu State, about a hundred years ago, when the Yin Shang was in the summer, the Ye family left a branch in the Xu State in order to share the risk, not only the Ye family, but also the other families also left branches in the Xu State, but the Yin Shang was founded, and the main vein of several families naturally became the nobles of the Great Shang, and those who stayed in the Xu State were naturally only side branches.

......

"I guessed correctly, those monks attached themselves to the Xia Dynasty in order to practice through the national fortune, and the national fortune declined, so they would naturally stand by and watch, because in an emerging country, the national fortune is always stronger than the decaying kingdom. I just don't know how Yin Lin and them killed those rookie cultivators. Feng Xue was very curious, but this kind of thing was not recorded in the history books.

"Spring and Autumn penmanship is a pit...... Oh, no, it's not spring and autumn yet. Feng Xue pursed her lips and tried to find other information, such as the policies after the establishment of Dashang or something.

Then he laughed.

After the Yin family ascended to the throne, the first thing was to establish the Xu Gong Temple within the entire Dashang radiation range, and worship Xu Feng as the ancestor of the Great Shang, in addition to Xu Feng himself, the temple also enshrined the thirteen sages of Xumen, and the three branches of the Li Sanke were also known to the world because of this.

This Yin family is also bold, and they can really put the ancestors who should be in the family temple as a foil in other people's temples, and they are not the first in the seat.

However, this also proves that even if the big business is in full swing now, for the people, the identity of the ancestor of the big business is not as important as the thirteen sages of the Xu Sect.

After a general glance at the development of the Terran industry and commerce, Feng Xue showed a pleased smile, and then he withdrew the information from the history books and began to focus on the inheritance of the Ye family.

Because this identity seems to be the relationship between the Ye family of Xu Guo, the secret inheritance in this family is "public" to Feng Xue, so he can directly get the corresponding inheritance.

And what he is most present in is the development of the qi and blood spell.

After five hundred years of study and development, the Ye family's qi and blood secret techniques are very different from those back then, perhaps because of his specialization in medicine, Feng Xue has seen many techniques for qi and blood guidance, pushing the uterus and invigorating blood, but compared to these, what makes him speechless the most is that he saw a minimally invasive surgery.

To put it simply, it is to remove tumors and bone spurs in the body by controlling blood and blood vessels, and at the same time, it can also dredge blood vessels, destroy blood clots, and treat high blood pressure......

"This is really a way to play!" Feng Xue was really interested in the spell developed by the Ye family, and she forgot the time as she flipped through it.

The baby's brain couldn't support him with such a high intensity of study, and it didn't take long for him to fall asleep again, so he woke up to read, cried when he was hungry, and slept when he was tired, and a month passed slowly, and Feng Xue also discovered that the biggest change in the development of this qi and blood forging technique has been so far-

The essence blood required by the longevity extension method is no longer extracted from others.

According to the theory of a certain ancestor of the Ye family, after the sperm blood is drawn from others, the person who is extracted from the sperm blood needs to take the medicine to make up for it, which shows that the medicine can replenish the essence and blood, so why can't you take the medicine yourself?

Based on this principle, the ancestors of the Ye family wrote down the two arguments of "absorption theory" and "overflow theory", believing that there is an upper limit to the essence that the human body can produce, and the essence of ordinary healthy people will be maintained in a relatively overflowing state, and people will age, not because of the deficiency of essence, but because the upper limit of essence is constantly decreasing. To draw qi and blood from others is to forcibly increase this upper limit, so as to prolong life.

So, he spent a lot of effort to study how to spontaneously break this upper limit, after several generations of sorting and perfecting, to now, it turned into a spell called "taking food", the essence of this spell can temporarily store qi and blood into the acupoint, so that he becomes a state of loss, and then replenish the qi and blood by taking medicine, and finally release the qi and blood contained in the acupoint, and then be able to complete the breakthrough on its own.

Although this method seems to be a bit like taking off your pants and farting, Feng Xue seems to have touched some threshold of cultivation.

If the trick point is replaced with a dantian, then this act of inputting qi and blood into the trick point is not very similar to the internal force cultivation in modern martial arts novels?

ps: Regarding the function of Lingbao's "dissemination", things with confidentiality cannot be obtained, this is conceptually determined, and his Lingbao's ability is derived from the "dissemination of knowledge", which itself is relative to the characteristic of "secrecy", which is a bit like the clerical conflict in DND, but if the secret object itself contains Feng Xue himself, it can still be seen, because conceptually speaking, this information is kept secret to others, but it is "open" to him.
