Sun Xiangfu swore that he agreed to let Sun Simiao have it checked purely because he was curious about how the male reproductive system was examined during this period.

"Well, the head is as big as a mushroom, the blood vessels are as loose, the feet are soft and elastic, and the congestion is as hard as a pestle, so there is no problem. Poor Dao will help you diagnose the pulse. ”

Hearing this, Sun Xiangfu was pardoned, and quickly lifted the crotch of his pants and stretched out his arm.

After a while, Sun Simiao nodded and said, "It's all peaceful, and there are no visions." ”

Sun Xiangfu withdrew his arm and said, "Of course there is no vision, I don't want children, that's because I want to have a planned birth." ”

"Planned Birth?" Sun Simiao was stunned.

"That's right, haven't you noticed that most of those pregnant women who died in childbirth were too young to conceive and had accidents when they had their first child?" Sun Xiangfu explained.

Hearing this, Sun Simiao was stunned again, he has a lot of research on gynecology, and he has handled many cases, recall it carefully, it is really as Sun Xiangfu said.

"And how do you control whether or not you get pregnant?" Sun Simiao asked puzzled.

"Well, there's a way to calculate the safe period······"

Next, what Sun Xiangfu said, Sun Simiao couldn't wait to record it with paper and pen, fortunately, Sun Simiao is not a person who breaks the casserole and asks to the end, he will only find a chance to test by himself, this old man is a man who is fifty or sixty years old and still gives birth to a son, and the history books record that he has three sons, all of whom were born after the age of sixty, of which the eldest Sun Xing served as a high-ranking official in the Gaozong Dynasty.

On the issue of human reproduction, Sun Xiangfu chatted with Sun Simiao for an afternoon, but Yu Xiu'er, who was waiting outside, was frightened, afraid that there was something wrong with Sun Xiangfu.

"Hehe, Madam doesn't need to worry, according to poor Dao calculations, Zhengming has a lot of heirs in this life, and there are at least three sons-in-law alone."

Looking at Yu Xiu'er, who was becoming more and more anxious, Li Chunfeng smiled with a relaxed expression.

"Can the Taoist figure figure this out?"

Just as Yu Xiu'er looked at Li Chunfeng in puzzlement, Sun Xiangfu pushed the door and walked out, and said to Li Chunfeng in surprise.

"Carving insect subtotal, carving insect submeter."

Hearing Li Chunfeng say that this was a 'plan', Sun Xiangfu suddenly understood, he said this just for the sake of An Yu Xiu'er's heart.

However, the matter of pregnancy and childbirth does have something to do with the quality of the mentality, Sun Xiangfu and Yu Xiu'er got married in the first year, Yu Xiu'er was under the repeated urging of Yu Chang and his wife, very psychologically pressured, naturally it is not so easy to conceive, and after figuring out the time of Yu Xiu'er's menstrual affairs, Sun Xiangfu has always maintained control over the sexual affairs, after all, he has been in love several times in his later life, and he has gathered less and separated more in the past two years, of course, it will not be so easy to be recruited, but now Yu Xiuer is about to turn eighteen years old, and the plan to have a child, It's time to put it on the agenda.

"Okay, lady, Daochang Sun also said, I am destined to wait for the heir to come later, but it is a good thing, I am afraid that I will not be able to take care of it at that time."

Even if Yu Xiu'er is thick-skinned, it is not good to discuss the matter of having a child in front of outsiders, so she blushed and retreated in a hurry, Sun Xiangfu said to Li Chunfeng, "I talked to Sun Daochang about some medical things, and I feel that if you want to treat more people, you must popularize medicine. ”

"Free medical care? Same as Lingnan? When Li Chunfeng heard this, he asked with some excitement in his heart, if the Dao Sect has something to do with such great merit, it will be difficult to destroy it after that.

Sun Xiangfu shook his head and said, "No, the medical school is for all the people in the country, but it is not like Lingnan, but it is only for the epidemic disease of all ethnic groups in Baiyue. As for the doctor's room and board, it can be borne by the Metropolitan Governor's Office, and the treatment is favorable. ”

"This is also a great merit, so Poor Dao went to his uncle and asked him to call on all the medical masters to come to Shanyang to discuss this matter."

Li Chunfeng is usually a strong supporter of doing good deeds, and after he has enjoyed the kind of eyes that others are grateful and adoring to him in Lingnan, doing good deeds has become a habit for him.

After all, if you want to make achievements in medicine, first of all, you have to understand the properties of medicine and prescribe medicine, which requires a certain literary foundation, and people with a written foundation, unless they are in the imperial court and can't do an errand, they will choose to study medicine, this situation is rare, yes, a large part of the doctors in the early Tang Dynasty are part-time Taoist monks, which is no wonder that these two religions will develop rapidly in this era, because the people's demand for medicine is great.

There are still a lot of vacant land in Shanyang City, and building a medical school is a matter of Sun Xiangfu's words, however, the northern land is not rich in medicinal materials, how to reduce the cost of medicine, Sun Xiangfu still needs to do more research, medicine field, which is very common in later generations, in this era, there is no such thing.

This point, when Sun Xiangfu came back from Lingnan, he already knew that the medicinal materials of this period were picked wild by doctors, which was bound to make the scale of medicine production small, the quality was uneven, and because of the less, it was easier to be raised in price, and the poor could not afford to cure the disease, so it was easy to drag a small illness into a big problem, and eventually died, which is also one of the main reasons why the average life expectancy in this period was not long.

However, although Sun Xiangfu of later generations came out of the University of Agricultural Sciences, his main research direction is crops, and he needs a lot of research to understand the growth habits of various medicinal materials and soil demand conditions.

"If the Taoist can unify the names of the medicinal materials he has, explain the attributes in detail, and compile them into a book, I am afraid that he will be meritorious for all generations."

After a day's discussion with Sun Simiao, Sun Xiangfu felt and said.

In later generations, Li Shizhen's "Compendium of Materia Medica" brought great benefits to the entire history of Chinese medicine, immeasurable, however, Sun Simiao's current research is mainly in medicine, and the "Qianjin Prescription" written by him will not be completed until the second year of Yonghui, which can be regarded as an encyclopedia of clinical treatment research in this period.

And what Sun Xiangfu wants to do is to promote medicine, how to promote it? The first thing is to make medicine simpler, so that all people, by reading books, know the medicinal properties of all medicinal materials, then studying medicine will become simpler.

"What the Metropolitan Governor said is very true, but if you want to complete this, I am afraid it will take a long time."

During the Ming Dynasty, the conditions in all aspects were much better than those of the Tang Dynasty, but it took Li Shizhen twenty-seven years to compile the "Compendium of Materia Medica".

"It's okay, I have money here, it's simple to call on more people to do this, once the medical school is established, you only need to be in the middle to co-ordinate, do research, and run errands, and I can send you a lot of people." Strive to bring my Datang's medical level to a new level within ten years. ”

Money is a good thing, driven by it, many crafts can progress rapidly, the reason why Sun Xiangfu makes so many money-making things out, is to accumulate capital, to promote the progress of this society, for the money to collect, or to pass it on to future generations, Sun Xiangfu did not think that the huge wealth may not bring his children and grandchildren any good enjoyment, but also harm them have no ability to forge ahead and survive, to be a parasite of society, there is no future.

When the concept and planning of the medical school were gradually taking shape, Yi Nan's men and horses finally arrived at the city of Dingxiang, and the eldest grandson was so frightened that he almost abandoned the city and fled, but fortunately, Su Dingfang, who came back from the west, entered the city one step ahead of Yinan.

Although Su Dingfang is a logistics officer, he also participated in the war this time, in order to ensure that the battle is foolproof, Li Jing used all the forces that can be used, so Su Dingfang did not come back empty-handed, he also brought back more than 20,000 young people who were half of Hu Banhan, most of these people were the border people of the Tang Dynasty who were plundered by Jieli in the early years, and the proportion of Chinese speakers was as high as eighty percent, even if they couldn't speak, most of them could understand it.

This is the best source of soldiers in the Metropolitan Protectorate of Anbei, as the commander in charge of the military, Su Dingfang naturally will not let go of this opportunity, and it just so happens that Li Jing also owes Sun Xiangfu a favor, so these people were brought back by Su Dingfang in advance.

Yi Nan didn't think about starting a war with Sun Xiangfu, and the tribe he brought was only 50,000 young people in the headquarters, and the Tang army that had more than 30,000 young people before and after, and guarded according to the city, the strength was actually not much different.

After receiving a letter from Yi Nan requesting a meeting, Sun Xiangfu almost did not hesitate, and agreed to meet him, asking Guo Po to lead 3,000 men and horses to defend the city, and he led Xi Junmai, Abu Tusi, Zhang Ke and 2,000 cavalry led by Xue Li, plus some personal guards, and went to Dingxiang City.

"Dadu Governor, if Yi Nan makes any changes, he will definitely shoot his head with an arrow."

Seeing that Sun Xiangfu was wearing a bloated armor and an oversized helmet, and from time to time he told the guards to get closer to him, Xue Li, as the deputy commander of the pro-guard team, couldn't look at it and said loudly.

He didn't know that this was Sun Xiangfu's habit of going out on expeditions, although he knew that Yi Nan didn't want to start a war with the Tang Dynasty, but there were no family members who deliberately created assassinations and provoked wars, dangerous people like Wang Hao and Wang Lin, there are many people with five surnames and seven families.

"Xue Li! Ben Governor tells you a truth, there is no big mistake in being careful. ”

The contemptuous look was discovered, and Xue Li said with some embarrassment, "Well, the last general knows, the Grand Governor wants the last general to be cautious at all times." ”

"The children can be taught! How have you been practicing kung fu lately? Sun Xiangfu looked at Xue Lidao, who looked like he was being taught, with a praising face.

"Hehe, the Governor's Mansion has good wine and meat every day, and this strength has increased a lot in the end." Xue Li replied with a smile.

Hearing this, Sun Xiangfu nodded and said, "Okay, when you see Yi Nan, you have to be as arrogant as possible, and it's best to pick out the people who his subordinates think are the most fierce and clean them up." ”

"Hehe, if you look for him, even if you find the wrong person, I should do the trouble-stirring thing." Xi Junmai didn't know when, and the horse arrived not far from Sun Xiangfu, and answered.

"Well, didn't the Metropolitan Governor say that Yi Nan didn't want to start a war with my Datang, why do you still want to take the initiative to provoke a war?" Xue Li asked very clearly.

"Yi Nan doesn't want to, then let's make him even more unwanted, let him know that my Datang wiped out Tuli and Jieli between hands, not by luck, but by strength, between nations and nations, only real strength will make the other party respect, so even if Yi Nan doesn't plan to provoke trouble, we have to show force in front of him."

Hearing this, Xue Li fell into thought, but Xi Junmai was overjoyed, doing this kind of thing was too appetizing for him.
