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

When Zhao Xu approached, Zhu Yuanzhang asked: "Why don't you make up for that breach?"

Zhao Xu did not say that the gap was opened by His Majesty the Emperor, nor did he say that it was for the convenience of travel. He just said: "The junior officials have been sick recently, and the junior officials cannot make the decision. Moreover, the house is guarded by robes. I’m not afraid of anyone daring to break in.”

Zhu Yuanzhang just asked, and after listening to Zhao Xu's words, he strode towards the gap.

The guards quickly followed.

In the mansion, beside a rockery in the north of the garden, Zuo Qi was talking to a well-dressed middle-aged man with a fat face. When he saw His Majesty the Emperor and his entourage approaching, he immediately abandoned the man and hurried to meet him.

Zhu Yuanzhang stopped Zuo Qi from seeing him, looked at the fat-faced middle-aged man not far away who was bowing to him with a smile, and asked Zuo Qi: "Who is that?"

"My lord bought a cook a few days ago, and she has a daughter in the former owner's house..." At this point, Zuo Qi paused with a slightly weird expression before continuing: "My lord, help her get her daughter, then This is the former master. He wanted to kowtow to you, but the younger one said that he was taking a nap and he refused to leave and had to wait."

After Zhu Yuanzhang heard this, he was immediately displeased. He actually sold his own mother after having a daughter. This is what people do. He waved his hand in disgust and said: "Send it away quickly. No pickled things are allowed in."

Zuo Qi quickly agreed and turned around to chase the people away.

Zhu Yuanzhang did not go straight to Zhu Yuan's inner house, but was led by Zhao Xu to the hall where Zhu Yuan usually received guests. After settling in for a while, Zhao Xu quickly went to call his junior officials.

When Zhu Yuan arrived, Lao Zhu was holding a copy of Song Dynasty chess book "Wangyou Qingle Ji" in the hall tea room, flipping through it and making moves.

After sending Zhao Xu out, who was following him, he also ordered that no one be allowed to come near, watching from a distance. Then Zhu Yuan turned around, knelt down, and said in awe: "My grandson has met his ancestors."

When Lao Zhu heard what Zhu Yuan said, a chess piece that was about to fall was stuck in the air, and then he whispered: "Get up."

Zhu Yuan stood up.

Lao Zhu gestured impatiently: "Come and sit down. You have a body like yours that can stand up. How polite."

Zhu Yuan then carefully came and sat down opposite Lao Zhu.

In fact, it was also a deliberate gesture.

Zhu Yuan didn't want Lao Zhu to think that he had changed his attitude because a certain relationship was exposed, or even felt arrogant or something like that.

Lao Zhu waited for Zhu Yuan to sit down and pushed a jar of chess pieces next to him: "Play chess with me."

When Zhu Yuan saw that Lao Zhu was pushing white stones, he carefully pushed them back and replaced them with black stones. This was only known recently. Bai was Qian and Hei was Kun. The women around him all asked him to use white stones when playing chess with him. In addition, this It's still the white man who goes first.

As for the later game of Go, Zhu Yuan had only heard of one rule: Black goes first, but he didn't understand anything else.

After changing the chess pieces, Zhu Yuan saw that Lao Zhu had drunk half of the tea in his hand. He took the initiative to pick up the teapot and help refill it. He also poured himself a cup and put it next to him. Then he said: "My grandson has only recently started to learn chess. I may not be able to let my ancestors enjoy it as much as possible." .”

Lao Zhu rarely plays chess on weekdays, and his chess skills are also average. He didn't say much, but just pointed to the opening that was already laid out on the chessboard: "Let's play like this."

Zhu Yuan nodded.

The two began to fall in love.

After a moment of silence, seeing that Lao Zhu remained silent, Zhu Yuan could probably guess his recent thoughts. Zhu Yuan once again took the initiative to start the topic: "Does our ancestors know why our grandson suddenly became seriously ill a few days ago?"

Zhu Yuanzhang was a suspicious and worried person, so of course he would not forget this matter, so he said directly: "Liu Ji?"

The "Book of Heaven" records that Liu Ji was supposed to resign in August this year, but this time, it was only the first month and Liu Ji had already returned to his hometown.

The matter did not match up with the "Book of Heaven", so naturally this boy was 'too worried'.

Lao Zhu did not think that the "Book of Heaven" was fake because he easily figured out the whole story.

This guy lived in Houhu. Cui Ji, the head of the Household Department, came to Houhu with his people to stir things up. He killed Cui Ji and others in order to scare the monkeys. Liu Ji spoke for Cui Ji to no avail, so he resigned angrily.

A very clear line of cause and effect.

Without Zhu Yuan, this period of cause and effect would not have happened.

Zhu Yuan nodded, shook his head again, and said: "Not only Mr. Liu, but also our ancestors did too many things in advance, which caught our grandson off guard."

Zhu Yuanzhang was confused.

Zhu Yuan thought for a moment and said: "Ancestor, there is a saying in later generations that a butterfly flapped its wings and brought up a breeze. This breeze continued to expand, and when it reached another place far away, the breeze had evolved into

A storm, this phenomenon is called the 'butterfly effect'. In fact, we in China also have a similar saying, called 'a slightest difference can make a difference a thousand miles'. This is all about the same truth, the small things at the beginning of something

Mistakes, as they develop, will lead to larger and larger deviations."

Lao Zhu understood and glanced at Zhu Yuan with a smile: "Is this why you have to live in seclusion for three years?"

Zhu Yuan nodded with a wry smile: "My grandson is that 'butterfly'. He wanted to avoid it actively and hoped that things would develop according to the "Book of Heaven". Unexpectedly, my ancestor made many changes in advance based on what his grandson said.

Not only Liu Ji, but also the "Essential Art of Qi Min" and so on. At that time, my grandson thought, if this continues, in three years, many things will be very different from the "Book of Heaven" written by his grandson. If this is true, the three

When my ancestor opens the "Book of Heaven" years later, his grandson will undoubtedly die."

Lao Zhu was silent.

Zhu Yuan waited for a while and said: "What my grandson actually wants to say is that because of the appearance of my 'butterfly', things have changed. As time goes by, the changes will only become bigger and bigger. Therefore, our ancestors no longer have to fight for the "Book of Heaven"

"Worry about the things contained in it."

Lao Zhu dropped a chess piece at random, with a thoughtful expression on his face. After a moment, he suddenly raised his head and stared at Zhu Yuan: "Liu was supposed to resign in August, but he resigned in the first month."

Zhu Yuan was puzzled for a moment: "Huh?"

Lao Zhu said: "Looking at Liu Ji, history has changed, but in the future, it may get better, but it can also get worse, right?"

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

He hadn't thought of this before.

Facing Lao Zhu's expression that gradually darkened again, Zhu Yuan thought for a moment, gestured to the chessboard in front of him, and said: "Ancestor, just like this chess game, beginners will definitely be confused, but after learning for a while, there are ancient chess records for reference.

, I will play better and better. My ancestors... because of me, it is equivalent to having played a game of chess, and I also have the history of the development of various countries in ancient and modern times at home and abroad in the next six hundred years as a 'chess record' for reference. Therefore, this newly opened game

The game must be better."

Zhu Yuan's metaphor made Lao Zhu feel a little relieved and nodded slightly.

However, when he thought of another thing, Lao Zhu quickly became sad again, paused, and finally said: "Queen... and Biao'er..."

Zhu Yuan understood what Lao Zhu wanted to ask and said softly: "What kind of illness the empress has is a matter deep in the palace and has no record in history. His Royal Highness the Crown Prince visited Shaanxi and was tired all the way and caught the cold."

Lao Zhu already knew the reason for the death of the prince from the "Book of Heaven". As for Ma family, Zhu Yuan's answer was also what he expected.

After a moment of silence, Lao Zhu finally asked, "Is there any way?"

Zhu Yuan nodded without thinking and said: "Yes, my grandson and Imperial Physician Dai talked about some medical matters for future generations this morning. Does my ancestor still remember the science of genes that my grandson mentioned at the beginning?"

Lao Zhu looked hopeful and said yes.

Zhu Yuan said: "According to the genetic structure, the limit of our life span is about a hundred years. Although the development of medicine in later generations has not been able to break through this limit, even the average person can live to be seventy or eighty years old. Before the grandson comes, , the average life span of our country’s people has reached seventy-seven years. As for people in the upper class, it is rare to live beyond ninety years, and a hundred years is not uncommon.”

After listening to Zhu Yuan's words, Lao Zhu felt that the two stones that had been weighing on his heart these days finally fell, and he couldn't wait to ask: "How to do it?"

Zhu Yuan did not answer immediately, but stood up and bowed his head and said: "Ancestor, before my grandson speaks, do you want to ask your ancestors for something?"

Lao Zhu was a little anxious and said impatiently: "Don't be too polite. Sit down and say, I agree to anything."

Zhu Yuan did not sit down, but said: "When my grandson studies history, he often sees that his ancestors often killed people because the doctors could not cure their diseases. There is a folk saying that 'doctors have the heart of their parents'. Doctors are just like parents, and parents look forward to it." Good children, this doctor’s nature must be to cure the patient. What’s more, we are a royal family, and doctors dare not give up their lives. However, manpower will eventually be limited. If the cure cannot be cured at one time, the ancestors will kill people, and they will definitely It makes doctors avoid the royal family, and even makes people dare not learn medicine. Even if the ancestors can force it, it will only make doctors tremble, not seeking merit but seeking no fault, unable to do their best. In the previous life, as recorded in the history books, the empress reached the end For a long time, he insisted on refusing to ask the imperial doctor for consultation or taking medicine, because he was afraid that after his death, his ancestors would blame the doctor again. Also, the prince's illness in his previous life... his grandson also had a cold before, which was almost gone, and he was cured. Therefore, after your grandson prays to his ancestors... unless there is an obvious fault, do not kill doctors at will, as this will only be counterproductive."

After hearing what Zhu Yuan said, Lao Zhu did not get angry, but fell silent again.

Zhu Yuan made it very clear.

In another life... the lady and Biao'er may have ended up like that because they killed too many doctors.

After being in such a daze for a while, Lao Zhu finally came back to his senses, looked at Zhu Yuan, and said with some inexplicable exhaustion: "Come and sit down, I will make a rule when I get back, as an ancestral rule, and I will never implicate the doctor at will in the future. "

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

Lao Zhu said urgently: "It's all your turn, tell me quickly, how to do it?"

Zhu Yuan said: "Ancestor, we can't rush this. The new medicine of my grandson's time took hundreds of years to develop..."

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

Zhu Yuan was startled and quickly pressed his hands: "Ancestor, don't be anxious, listen to me slowly."

Lao Zhu still stared.

Not to mention a hundred years, my wife... can only wait fifteen years at most!

Zhu Yuan saw that Lao Zhu looked like he was about to get violent and hurt anyone at any time, so he quickly speeded up his speech and said: "Ancestor, grandson, for example, if you go from Jinling to Xanadu, if you don't know the direction at all, you can only walk, maybe After going round and round, you can't reach it in a year. On the contrary, if you know the direction and road accurately and have a fast horse, you can arrive in ten days. The reason why later generations of medicine has been developed for hundreds of years before the average life expectancy exceeds 70, then This is because the predecessors did not know the direction and could only fumble. Now, my grandson knows the exact 'direction', and his ancestors can provide a 'fast horse'. Therefore, in just ten years, he may be able to achieve something. Moreover, not only medicine, grandson I know a lot of other knowledge. As long as the ancestors support it, the process of future generations will also take hundreds of years, and we can greatly shorten it."

Only then did Lao Zhu's expression soften.

He nodded, looked at Zhu Yuan and praised: "You are always able to explain profound truths in simple terms, so you are very suitable to be a teacher."

Zhu Yuan laughed in agreement.

This compliment...

At least you relaxed and didn't get beaten, right?

Taking a sip of the tea at hand to moisten his throat, Zhu Yuan continued: "Furthermore, ancestors, some daily things that can prolong life in future generations can be done without too much advanced new medicine. As the saying goes, 'Disease enters from the mouth.

', and there is also a saying that 'overwork leads to illness'. As long as you develop good daily eating habits, people will not easily get sick."

Lao Zhu gestured: "Tell me?"

Zhu Yuan thought for a moment and said: "For example, food and water must be boiled before drinking. There is also meat. You must not eat raw meat. It must be thoroughly cooked before eating. By the way, there are also tableware and silverware.

The tableware made of it is the best, better than gold."

Lao Zhu asked in confusion: "Why are these?"

"Because raw water, raw meat, etc., may contain bacteria and parasites, which are the source of disease. My grandson said that it is best to use silverware for tableware, because this silverware has a natural sterilization effect..." He said,

Seeing that Lao Zhu was still confused, Zhu Yuan added a little: "These are tiny living creatures that are invisible to our naked eyes. By the way, some parasites are visible, while the invisible ones are bacteria and viruses. Later generations are collectively called microorganisms. Our ancestors can

Remember what I said about cells in genetics: humans are made up of hundreds of millions of cells, but those microorganisms are only one cell in size, or even smaller viruses are just a piece of gene."

Lao Zhu hit the nail on the head: "I was curious about this at the beginning. How could you know if you couldn't see it?"

Zhu Yuan said: "It's just invisible to the naked eye. I also chatted with Mr. Dai in the morning that we can make a microscope, which magnifies the object... not itself, but the image, 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 medicine to deal with them."

Lao Zhu asked with some suspicion: "What kind of microscope can you make?"

Magnifying an object, even an image, hundreds or thousands of times, in Lao Zhu's opinion, is inseparable from the magic of gods and Taoism.

"The principle is very simple," Zhu Yuan said, walked to the desk next to him, took out a page of white paper, dipped a drop of tea in the cup, and touched it on the paper: "Ancestor, please see, through this drop of drum

The blisters have caused the texture on the paper to become a bit enlarged?"

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

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

Seeing the curious Lao Zhu, Zhu Yuan made another drop of water and followed the same method, and then made another drop. It seemed that he had found a new world. He could only let his ancestors play and say: "This is a common magnifying glass in later generations. If a magnifying glass can magnify three

Ten times, two magnifying glasses are superimposed, thirty times thirty, which is nine hundred times, and you can basically see most microorganisms. Our ancestors made this magnifying glass, and later generations used glass. Nowadays, transparent crystals can be used instead, so we need to find crystals.

Mineral deposits. This crystal is actually very useful, not only as a microscope, but also as a telescope, as well as reading glasses for correcting people’s vision, myopia glasses, etc.”

Lao Zhu had enough fun, finally sat down, nodded and said: "I will also give special instructions later on, asking General to search for crystal mines as soon as possible. You... what you just said about your daily life, continue."

Zhu Yuan said: "Another example is the various furniture and utensils used in daily life. Things containing lead and mercury should be kept away. These metals are poisonous. Long-term exposure will cause great damage to the human body, let alone the Taoist practice of elixirs."

Taking the medicine is the same as committing suicide. In addition... there are too many, and the ancestors and grandchildren can't think of them at the moment. Let's slowly compile a charter in the past few days and then give it to the ancestors?"

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

Zhu Yuan said: "First of all, there are people. Later generations will have specialized medical universities that can train thousands of doctors every year. We can't reach that level now, but we still need to gather a group of doctors who are willing to study and study. In addition, ancestors and grandchildren

I also suggested selecting a group of women to study medicine."

Lao Zhu was not immediately dissatisfied, but asked: "Why choose a woman?"

Zhu Yuan said: "It is always more appropriate for women to treat women's diseases. 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 didn't matter at all. He quickly said: "I'm sure, you will be responsible for choosing the person."

Zhu Yuan added: "Also, some actions of later generations of medicine may be contrary to current ethics."

Lao Zhu did not ask questions immediately, but just waited for Zhu Yuan to continue.

Zhu Yuan said: "For example, in the study of anatomy, our ancestors should understand what the name means. If you want medicine to develop, you must first have a deeper understanding of the human body. Therefore, this study of anatomy can be said to be a foundation for new medicine in later generations."

As he said this, Zhu Yuan noticed that Lao Zhu had a strange expression.

After thinking for a while, he suddenly understood and said quickly: "My ancestors misunderstood, it is not anatomy of living people, but anatomy of corpses. The sources of dissections for later generations are, first, the execution of extremely heinous felons, and second, the remains of those who were willing to donate their bodies to medicine during their lifetime.

These are all in accordance with regulations and will not be messed up."

When Lao Zhu heard that he was not dissecting a living person, he relaxed. After thinking about it for a while, he quickly agreed: "You go ahead and do it. If someone makes noise in the future, I will chop him up and send him for dissection."

Zhu Yuan: "..."

I have no intention of doing it myself!

After muttering something in his heart, Zhu Yuan was about to speak when he suddenly remembered another thing and said instead: "Ancestor, there is another matter that is not related or unrelated, a big matter."

Lao Zhu was confused: "What's the matter?"

Zhu Yuan said: "I chatted with Imperial Physician Dai about the origin of the disease in the morning. In short, the army is currently fighting, and the most important thing is to dispose of the corpses. Whether human corpses, chickens, ducks, cattle, or sheep, they 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 disease is epidemic. Our ancestors should know that the famous Han general Huo Qubing is rumored to have died from the disease caused by the Xiongnu deliberately discarding the carcasses of cattle and sheep. Therefore, our ancestors had better issue a strict order as soon as possible. Both the enemy and us, whether human or otherwise, inside and outside the battlefield, in the event of a war,

During the break, the first thing to do is to bury the body."

Saying this, Zhu Yuan thought of the small village where he woke up again.

At that time, he had been wandering around with the refugees for a day in a daze, and now he had completely forgotten where the small village was. He only hoped that the poor people who had been affected by the war had been buried in peace.

Lao Zhu also lowered his expression.

He can deeply understand the horror of this epidemic. Back then...

Not wanting to think about that sad past, Lao Zhu said with a serious expression: "As soon as I return to the palace, I will have someone rush to pass on the order."

Zhu Yuan thought for a while and said: "In that case, ancestors, there is nothing else for the time being. As my grandson just said, this new type of medicine cannot be achieved in a day or two, and can only be implemented slowly."

Lao Zhu combed through the previous discussions between the two of them, took note of the key points, and nodded without rushing in any further. Suddenly he changed the topic again, stared at Zhu Yuan and asked in a deep voice: "Yuan'er, that "Book of Heaven"

Above all... tell me the truth, how did the second and third children die?"


Chapter completed!
