Zhu Yuanzhang rode to Houhu Island surrounded by guards, and saw that there was still a big gap in the west wall of Zhu Yuan's mansion, and he still couldn't help but sigh when he thought of what happened that night.

When Zhao Xu approached, Zhu Yuanzhang asked, "Why don't you make up for the gap?" ”

Zhao Xu didn't say that the gap was opened by His Majesty the Emperor, let alone greedy for convenience, but just said: "The little officials have been sick for a while, and the little ones can't be the masters." And the house is guarded by robes, not afraid that anyone will dare to break in. ”

Zhu Yuanzhang just asked, and when he heard Zhao Xu say, he had already strode towards the gap.

The guards hurriedly followed.

In the mansion, next to a rockery on the north side of the garden, Zuo Qi was talking to a middle-aged man with a fat face who was dressed decently, and when he saw His Majesty the Emperor and his party coming over, he immediately abandoned the person and hurried to meet him.

Zhu Yuanzhang stopped Zuo Qi from saluting, looked at the fat-faced middle-aged man who was smiling and bowing to him not far away, and asked Zuo Qidao, "Who is that?" ”

"The adult bought a cook a few days ago, and there is a daughter ...... at the former master's house" Speaking of this, Zuo Qi's expression paused a little strangely, and then continued: "The adult helped her ask for her daughter, that is the former master, and wants to kowtow to the adult, and the little one said that the adult is taking a nap, and he refuses to leave, so he has to wait." ”

After hearing this, Zhu Yuanzhang was immediately displeased, and when he had a daughter, he even sold his mother, which was done by people, and waved his hand in disgust: "Hurry up and send it away, let anything pickled into the door." ”

Zuo Qi hurriedly agreed, turned around and went to catch up.

Zhu Yuanzhang did not go straight to Zhu Yuan's inner house again, but went to Zhu Yuan's hall where he usually met guests under the guidance of Zhao Xu, and settled it slightly, and Zhao Xu hurriedly called his own petty officials.

When Zhu Yuan arrived, Lao Zhu was holding the Song Dynasty chess book "Forget Worries and Qing Music Collection" in the tea room of the hall and reading it while flipping through it.

Zhao Xu, who was sent to follow, went out, and ordered to watch from a distance and not allow anyone to approach here, so Zhu Yuan turned around and knelt down, and said, "My grandson has seen my ancestors." ”

Lao Zhu heard Zhu Yuan say this, and a chess piece that was about to fall was stuck in the air, and then he said softly: "Get up." ”

Zhu Yuan stood up.

Lao Zhu motioned impatiently: "Come and sit, you can stand in this body, and be polite." ”

Only then did Zhu Yuan carefully come to sit down opposite Lao Zhu.

In fact, it is also a deliberate posture.

Zhu Yuan didn't want Lao Zhu to feel that he had changed his attitude because of a certain level of relationship, and even pampered and arrogant.

Lao Zhu waited for Zhu Yuan to sit down, and pushed over a can of chess pieces in his hand: "Accompany me to play chess." ”

Zhu Yuan saw that Lao Zhu pushed over Baizi, so he carefully pushed it back and replaced it with a sunspot. This is something that has only recently been learned. White is dry, black is kun, and the women around him play chess with him, and let him use white. In addition, in this era, it was Bai Zi who went first.

As for the later Go, Zhu Yuan had only heard of a rule that led to black, and he didn't understand anything else.

After changing the chess pieces, Zhu Yuan saw that Lao Zhu drank half of the tea in his hand, took the initiative to pick up the teapot to help refill it, and also poured himself a cup and put it next to him, and then said: "My grandson has only recently started to learn chess, and I am afraid that I can't let my ancestors enjoy themselves." ”

Lao Zhu rarely plays chess on weekdays, and his chess skills are also average, so he didn't say much, but just signaled to the opening game that had been laid out on the chessboard: "Just play like this." ”

Zhu Yuan nodded.

The two began to fall.

After being silent for a moment, seeing that Lao Zhu had not spoken, he could probably guess his recent thoughts, Zhu Yuan took the initiative to start the topic again: "Ancestor does know why his grandson suddenly fell seriously ill a few days ago?" ”

Zhu Yuanzhang is a suspicious person, of course he will not forget this matter, and said directly: "Liu Ji? ”

The "Book from Heaven" records that Liu Ji should resign in August this year, but this time, it is the first month, and Liu Ji has already returned to his hometown.

Things don't match the "Book from Heaven", and this kid is naturally 'too worried'.

Lao Zhu didn't think that "Book from Heaven" was fake because of this, because he easily figured out the ins and outs.

This kid lives in Houhu, Cui Ji, the head of the household department, brought people to Houhu to tease, and he cut Cui Ji and others in order to kill chickens and monkeys, Liu Ji spoke fruitlessly for Cui Ji, and resigned angrily.

A very clear line of cause and effect.

If there were no Zhu Yuan, there would be no cause and effect.

Zhu Yuan nodded, shook his head again, and said, "It's not just Lord Liu, but also, the ancestor has done too many things in advance, which caught his grandson off guard. ”

Zhu Yuanzhang was puzzled.

Zhu Yuan thought for a moment and said: "Ancestor, there is a saying in later generations that a butterfly flapped its wings and brought a breeze, and this breeze continued to expand, and when it reached another place far away, the breeze had evolved into a storm, and this phenomenon was called the 'butterfly effect'. In fact, we also have a similar saying in Huaxia, which is called 'a millimeter of difference, a thousand miles of error'. This is all to say that a small mistake at the beginning of a matter will cause more and more deviations later on. ”

Lao Zhu understood, and glanced at Zhu Yuan with a smile: "This is why you have lived in seclusion for three years?" ”

Zhu Yuan nodded, with a wry smile: "Sun Er is the 'butterfly', I want to take the initiative to avoid it, I hope that things will develop according to the "Book of Heaven", but I didn't expect that the ancestors made a lot of changes in advance according to Sun Er's words. Not only Liu Ji, but also the "Qi Min Technique" and so on, at that time, Sun Er thought, if this continues, three years later, many things will be very different from the "Book of Heaven" written by Sun Er. If this is the case, three years later, the ancestor will open the Book of Heaven, and the grandson will definitely die. ”

Lao Zhu was silent.

Zhu Yuan waited for a while and said: "What Sun Er actually wants to say is that because my 'butterfly' appeared, things have changed, and the further I go, the change will only get bigger and bigger, so the ancestors don't have to worry about the things contained in the Book of Heaven. ”

Lao Zhu dropped a chess piece at random, his face was thoughtful, and after a while, he suddenly raised his head and stared at Zhu Yuan: "Liu basically should resign in August, but he resigned in the first month." ”

Zhu Yuan was puzzled for a while: "Huh? ”

Lao Zhu said: "Referring to Liu Ji, this history has changed, but in the future, it may be better, but it can also get worse, right?" ”

Zhu Yuan opened his mouth slightly, he didn't expect Lao Zhu to be so keen.

He hadn't thought of that before.

Facing Lao Zhu's gradually sinking expression, Zhu Yuan pondered, gestured to the chessboard in front of him, and said: "Ancestor, just like this game of chess, beginners must be ignorant, but after learning for a period of time, and then there are ancient chess games as a reference, it will definitely get better and better." Ancestors ...... Present Because of me, it is equivalent to having already played a game of chess, and I also have the history of the development of ancient and modern Chinese and foreign countries in the next 600 years as a reference for the 'chess game', so this new game will definitely be able to play better. ”

Zhu Yuan's analogy made Lao Zhu Sheng a little stunned, and nodded slightly.

It's just that thinking of another thing, Lao Zhu's expression was gloomy again, he paused, and finally said, "Queen...... And the standard ......"

Zhu Yuan understood what Lao Zhu wanted to ask, and said softly: "What kind of illness Niangniang has, it is a matter of the deep palace, and there is no record in history. His Royal Highness the Crown Prince was tired all the way after inspecting Shaanxi, and he got cold. ”

Lao Zhu already knew the reason for the death of the prince in the "Book of Heaven", and as for the Ma family, Zhu Yuan's answer was also expected by him.

After being silent for a moment, Lao Zhu finally said tentatively: "Is there a way?" ”

Zhu Yuan nodded without thinking about it: "Yes, my grandson talked to Imperial Doctor Dai about some medical matters in the future this morning. Do your ancestors remember what their grandchildren mentioned about genetics? ”

Lao Zhu looked hopeful and snorted.

Zhu Yuan said: "According to the genetic structure, the life limit of our people is about 100 years old. Although the development of medicine in later generations has not been able to break through this limit, even ordinary people have no problem living to be seventy or eighty years old, and before the grandchildren came, the average life expectancy of our people had reached seventy-seven years old. As for the people in the upper class, it is rare to live past the age of 90, and it is not uncommon to be 100 years old. ”

After listening to Zhu Yuan, the two stones that had been pressed in his heart these days finally fell, and he couldn't wait to ask, "How to do it?" ”

Zhu Yuan didn't answer immediately, but got up and said, "Ancestor, before your grandson said it, you want to ask your ancestor first?" ”

Lao Zhu was a little anxious and said impatiently: "Don't be polite, sit down and say, I will agree to everything." ”

Zhu Yuan didn't sit down, but said: "My grandson reads history, and I often see my ancestors killing people at every turn because they can't heal well. There is a folk saying that 'the heart of the parents of the healer', the doctor is just like the parents, the parents are looking forward to the well-being of their children, and the nature of the healer must be to hope to cure the sick. What's more, it's still our royal family, and the doctor doesn't dare to use his life. It's just that there will be a time when manpower will be poor. If it is not cured once, the ancestors will kill people, which will make the doctors avoid the royal family, and even make people dare not study medicine. Even if the ancestor can force the order, it will only make the doctor tremble, not seeking merit but seeking no fault, and unable to do his best. In her previous life, according to the history books, Niangniang insisted on refusing to let the imperial doctor consult or take medicine at the last moment, because she was afraid that after her death, her ancestors would blame the doctor again. Also, the illness of the prince in the previous life...... The grandson was also cold before, and it was almost gone, and he was cured. Therefore, the grandson begs for the ancestors...... Unless there is obvious fault, do not kill the healer at every turn, it will only backfire. ”

After listening to Zhu Yuan, Lao Zhu was not angry, but was silent again.

Zhu Yuan said very clearly.

Another life...... Niangzi, and Biao'er, may have killed too many doctors by herself, which caused the ending.

After being stunned for a while, Lao Zhu finally came back to his senses, looked at Zhu Yuan, and said inexplicably with some exhaustion: "Come and sit down, I will set up a rule when I go back, treat it as an ancestral system, and never implicate doctors at will in the future." ”

Zhu Yuan bowed again and returned to the table to sit down.

Lao Zhu said urgently: "It's all up to you, hurry up and talk about it, how to do it?" ”

Zhu Yuan said: "Ancestor, this can't be rushed, the new medicine of the grandson's era has developed for a hundred years, and it will only have ......."

Before Zhu Yuan finished speaking, Lao Zhu had already raised his voice with his eyes glared: "A hundred years?!" ”

Zhu Yuan was taken aback, and hurriedly pressed his hand: "Ancestor, don't worry, listen to me slowly." ”

Lao Zhu was still staring.

Don't say a hundred years, your own lady...... You can only wait fifteen years at most!

Zhu Yuan saw that Lao Zhu looked like he was about to break out and hurt people at any time, so he hurriedly sped up his speech and said: "Ancestor, grandson for example, if you go to Shangdu from Jinling, if you don't know the direction and road at all, you can only walk, maybe you can't get there for a year after going around." On the contrary, if you know exactly where you want to go, and if you have a fast horse available, you can reach it in ten days. The reason why the average life expectancy of medicine exceeded 70 in the past 100 years was because the predecessors did not know the direction and could only grope. At present, the grandchildren know the exact 'direction', and the ancestors can provide the 'fast horse', so it only takes ten years, or you can make achievements. Moreover, not only medicine, but also many other knowledge that grandchildren know, as long as the ancestors support it, the future generations will also need a hundred years of process, and we can greatly shorten it. ”

Lao Zhu's expression softened at this time.

He also nodded, looked at Zhu Yuan and praised: "You can always explain the profound truth in a simple way, but you are very suitable to be Mr. Xixi." ”

Zhu Yuan smiled cooperatively.

This compliment......

At least relax, not beaten, right?

After taking a sip of the tea in his hand and moistening his throat, Zhu Yuan continued: "Besides, ancestor, some daily things to prolong life in later generations can be done without too deep new medicine." As the saying goes, 'illness comes from the mouth', and there is also a saying that 'overwork becomes illness', as long as you develop good daily eating habits, people will not get sick easily. ”

Lao Zhu gestured: "Tell me?" ”

Zhu Yuan thought for a while and said: "For example, if you drink water on weekdays, you must boil it and drink it." There is also meat, which must not be eaten raw, and must be thoroughly cooked before eating. By the way, there are also cutlery, and silver cutlery is the best, better than gold. ”

Lao Zhu was puzzled and asked, "Why are these?" ”

"Because raw water, raw meat, etc., may be attached to bacteria and parasites, these are the source of disease, grandchildren said that tableware with silverware is the best, because this silverware naturally has a bactericidal effect......" said this, seeing that Lao Zhu was still puzzled, Zhu Yuan added slightly: "These are tiny living things that are invisible to our naked eyes, by the way, some parasites are visible, and what is invisible is bacteria and viruses, which are collectively called microorganisms in later generations." Ancestors remember me saying that in the science of genetics, cells are made up of hundreds of billions of cells, but those microorganisms are just a cell, or smaller viruses, just a gene. ”

Lao Zhu hit the nail on the head: "I was curious about this at the beginning, I can't see it, how do you know?" ”

Zhu Yuan said: "It's just invisible to the naked eye." I also talked with Mr. Dai in the morning about how you can make a microscope, that is, to ...... objects It's not the itself, it's the image, magnified hundreds or thousands of times, so that we can see all kinds of microorganisms. Only by seeing these microorganisms that cause disease can we find the right way to deal with it. ”

Lao Zhu asked with some suspicion: "What kind of microscope is this, can you make it?" ”

Magnifying an item, even if it is an image, hundreds or thousands of times, in Lao Zhu's opinion, is no different from the Immortal Dao.

"The principle is very simple," Zhu Yuan said, walked to the bookcase next to him, took a page of white paper, dipped a drop of tea in the cup, and put it on the paper: "Ancestor, please see, through this bulging blister, is the texture on the paper enlarged?" ”

Lao Zhu stood up directly and watched from top to bottom.

Sure enough, compared to the surroundings, the texture of the paper under the drop of water was significantly enlarged and clearer.

Zhu Yuan saw that the curious old Zhu personally made a drop of water to concoct it in the same way, and then made another drop, as if he had found a new world, so he could only let his ancestors say while playing: "This is a common magnifying glass in later generations, if one magnifying glass can be magnified thirty times, and the two magnifying glasses are superimposed, thirty times thirty, which is nine hundred times, and most of the microorganisms can basically be seen." Ancestors, to make this magnifying glass, later generations used glass, at present, can be replaced with transparent crystal, so it is necessary to find crystal deposits. This crystal is actually very useful, not only for microscopes, but also for telescopes, as well as reading glasses to correct people's eyesight, myopia glasses and so on. ”

Lao Zhu had enough fun, finally sat down, nodded and said, "I will also focus on instructing later, let the general Zuosi find the crystal mine as soon as possible." You...... What was the daily routine just now, and continued. ”

Zhu Yuan said: "Another example is the various furniture and utensils used on weekdays, things containing lead and mercury should be kept away, these metals are poisonous, and long-term contact will cause great damage to the human body, not to mention the Taoist practice of pills and taking them, it is no different from suicide." Other than that...... It's too much, my ancestors, and my grandchildren can't think about it for a while, so I'll slowly list a charter in the next few days and give it to my ancestors, right? ”

Lao Zhu thought about it, nodded in agreement, and quickly turned back to the previous topic: "And that new medicine, how to start?" ”

Zhu Yuan said: "First of all, there are people, and in later generations, there will be special medical universities, which can train thousands of doctors every year. We are far from this level now, but we must also concentrate a group of doctors who are willing to learn and study. In addition, the ancestors and grandchildren also suggested that a group of women should be selected to study medicine. ”

Lao Zhu was not immediately dissatisfied, but asked, "Why did you choose a woman?" ”

Zhu Yuan said: "It is always more appropriate for women to treat women's diseases, and the number of female doctors in later generations is not much less than that of male doctors." ”

Lao Zhu thought of Ma again, for the sake of his wife, this matter is not a matter at all, and quickly said: "If I am ready, you will be responsible for picking people." ”

Zhu Yuan said: "Also, some of the actions of medicine in later generations may be contrary to current ethics. ”

Lao Zhu didn't ask questions immediately, just waited for Zhu Yuan to continue.

Zhu Yuan said: "For example, the study of anatomy, the ancestors should understand what the name means. If medicine wants to develop, it is necessary to have a deeper understanding of the human body, so this anatomical science can be said to be a fundamental part of the new medicine in later generations. ”

Saying this, Zhu Yuan noticed that Lao Zhu's expression was a little strange.

After thinking about it, he suddenly understood, and hurriedly said: "The ancestor misunderstood, it was not a living person dissecting, it was an autopsy." The sources of autopsy in later generations are, firstly, the extremely heinous felons executed, and secondly, the bodies that are willing to be donated by the medical contributors before their deaths. ”

Lao Zhu heard that it was not a living person, he also relaxed, thought about it a little, and quickly agreed: "You let it go, if someone makes noise in the future, I will cut him down and send him for autopsy." ”

Zhu Yuan: "......"

I wasn't going to do it myself!

Saying something in his heart, Zhu Yuan was just about to speak, but suddenly remembered another thing, and turned to say: "Ancestor, there is another thing that is not related to it, a big event." ”

Lao Zhu was puzzled: "What's the matter?" ”

Zhu Yuan said: "In the morning, I talked with Imperial Doctor Dai about the origin of the disease, in short, the most important thing for the army to fight abroad is to dispose of the corpse. Whether it is a human corpse, or a chicken, duck, cow or sheep, it must be strictly buried. It is already spring, the weather is getting warmer, and if the body is not buried in time, it is easy to cause an epidemic. The ancestors should know that the rumored famous Han general Huo Qubing died of the epidemic caused by the Xiongnu deliberately discarding the carcasses of cattle and sheep. Therefore, it is best for the ancestors to issue a strict order as soon as possible, inside and outside the battlefield, whether it is friend or foe, whether it is human or otherwise, once the fighting is interrupted, the first thing is to bury the corpse. ”

Saying this, Zhu Yuan remembered the small village when he woke up.

He had been wandering with the fleeing people for a day, and now he had completely forgotten where the village was, and he only hoped that the poor people who had been affected by the war would be laid to earth.

Lao Zhu also gathered his expression.

He can deeply understand the horror of this epidemic, and he ......

Unwilling to recall the sad past, Lao Zhu said with a serious expression: "After I return to the palace, I will immediately let people pass the order." ”

Zhu Yuan thought for a while and said: "That is the case, ancestor, there is nothing else for the time being, or what Sun Er just said, this new type of medicine can not be done in a day or two after all, but can only be slowly figured out." ”

Lao Zhu combed through the various discussions between the two of them before, noted down the key points, and nodded without rushing to go deeper. Suddenly, he changed the topic again, stared at Zhu Yuan and asked in a deep voice: "Yuan'er, what is the "Book from Heaven"...... You tell me the truth, how did the second and third children die? ”
