"Oh yes, I just came to Chang'an on the way, and I heard a lot of rumors about me, why I said that close relatives, including cousins, can't get married, why I said that quicklime can be disinfected and remove epidemics, and what should be done to wash hands before meals can prevent diseases, etc., I said it?" Sun Simiao looked at Li Kedao with a smile.

"yes, isn't that what you said?" Li Ke said confidently.

Sun Simiao: "......"

"When did I say that?" Sun Simiao was a little speechless, "It seems that I have met Your Highness for the first time." ”

"That's what you just said." Li Ke asked with a grin, "Didn't you repeat it all?" ”

"Your Highness, you know that what the old man said is not what he meant." Sun Simiao was a little speechless, aren't you messing around? Obviously, Sun Simiao didn't know the seriousness of the matter at all, he had never met someone like Li Ke before, so naturally he didn't know the seriousness of the matter.

"Then I ask you, does this stuff make sense?" Li Ke asked with a smile.

"Yes, I have indeed studied a lot of the content in it, and I have thought about it systematically, although I have not yet summarized the pathology, but it does make sense." Sun Simiao nodded seriously, when discussing medicine, Sun Simiao was very serious, although Li Ke did not study medicine, but some of Li Ke's ideas were very groundbreaking for Sun Simiao.

So Sun Simiao naturally didn't mind discussing these with Li Ke.

"Isn't that enough? You know that, so you've said something similar in other places, isn't it true that you haven't told others to wash their hands often? Surely it can't be. Li Ke said with a smile, "If you said it, then I said it was you, no problem." ”

"Forehead......" Sun Simiao choked for a moment, as if ...... Makes sense? Although he felt that something was wrong, Li Ke's statement was not wrong, he really didn't say it in front of Li Ke, but he said it elsewhere, Li Ke said that he said it...... Seems to be right, too?

"Hey, what are we struggling with this, these things are actually summarized by some folk classics that I have collected, just like the disadvantages of consanguineous marriage, there have been some records since ancient times, but I think it is not only the ethical aspect, but also should not be placed on the cousin side. Mothers will also give their children some genetic information, otherwise why do some children look like their mothers? ”

"This shows that the children are acting on the common characteristics of the parents, and these characteristics will naturally bring changes to the child, which shows that the problems caused by the marriage of close relatives on the paternal side may also be caused by the maternal line." Li Ke tried his best to explain to Sun Simiao in his own straightforward language.

It's not that Li Ke wants to give Sun Simiao a lesson, but Li Ke buries Sun Simiao's words first, and when Li Shimin asks, then Sun Simiao will naturally think of what Li Ke said in his mind.

Lao Sun, a person who has studied in the medical field all his life, has already penetrated many things about these things into the bone marrow, and he will definitely say the correct medical theory.

The two of them rode horses side by side in the direction of Qin Wangzhuang, Sun Simiao suddenly asked: "In fact, the old man has been practicing medicine in the outside world for so many years, and there has always been a problem that has not been clarified. ”

Epidemic protection, Li Ke pondered for a while, and what Sun Simiao said about epidemic protection must refer to the epidemic, that is, the plague. Since ancient times, plague does not refer to the same disease, but is equivalent to a malignant infectious disease.

The plagues spread in ancient China generally referred to plague, smallpox, cholera, malaria, etc. Depending on the type of disease, the damage caused by these plagues varies, and is generally caused by poor sanitation after natural disasters.

But if you simply tell Sun Simiao some measures, it doesn't have much effect, what Li Ke needs is a policy that can solve the problem of epidemic prevention, in fact, he himself is looking for Sun Simiao, but also to prevent this.

The projects carried out by Li Ke are all projects with a very large flow of people, and this kind of project is the most prone to epidemics.

However, he didn't expect Sun Simiao to ask this question directly.

"Sun Zhenren, in fact, I don't understand medicine, but I have money." Li Ke thought for a moment, and then spoke.

Sun Simiao was a little puzzled, but he didn't say it casually, but waited quietly for the following.

"Although being rich is not everything, but to a certain extent, being rich is something you can do whatever you want, and after I got rich, I asked people to search for dozens of small countries around the entire Tang Dynasty, as well as medical books from countries farther away like Tianzhu, Persia, Dashi and even farther around the Mediterranean, and then summarized these books for research."

"On the whole, the medical books in different regions are not as developed as the medicine in our Central Plains, but they have elaborated on some pathologies and cases from different perspectives, which may bring more inspiration to people."

"Like, how disease arises."

"Has Sun Zhenren ever thought about a question, or rather, let me give you an example, has Sun Zhenren ever seen a case, that is, some children have worms in their stomachs, these worms don't know when to enter the human body, and then when these worms are in the child's stomach, they will cause all kinds of diseases, and after taking medicine to kill these worms and excrete them from the body, or directly discharge, the disease will be cured." Li Ke asked.

"Of course, it is recorded in the "Yellow Emperor's Neijing" and "Jin Kui Yaolu" that the ascaris disease originates from this, I don't know what His Highness wants to say." Sun Simiao was a little puzzled.

"Hehe, has Sun Zhenren ever thought about a question, how did this roundworm enter the human body? When some roundworms are excreted from the human body, they are very large, and it is certainly impossible for us to crawl into our bodies when we are asleep, so there must be a reason, and such insects should have eggs, am I right? Li Ke asked with a smile.

"Yes." Sun Simiao nodded.

"Is there a possibility, because the eggs are too small, we don't pay much attention to them, and some roundworm eggs will stay on some wild vegetables, melons and fruits, when people eat these things and do not clean, once the eggs enter the human body, it is easy to multiply in it and become roundworms."

"I have asked people to investigate all the gate valve families and nobles, and there are almost no roundworms in the homes of rich people who pay more attention to hygiene and clean these vegetables and fruits." Li Ke said with a smile.

"This old man can understand." Sun Simiao nodded and said, what is incomprehensible about this, insects must have eggs, and it must be eggs that enter the human body in different ways, Sun Simiao can naturally understand.

"Sun Zhenren, do you think there is a possibility that all kinds of diseases in the world are actually composed of all kinds of small insects? It's just that these little insects are too small and too small, so small that they are smaller than the eggs of roundworms, and even so small that our human eyes can't see them, so they form all kinds of diseases after entering our human body? Li Ke asked with a smile.
