Li Chengqian recovered from illness, and many people were happy. Of course, some were unhappy, that was his younger brother Li Tai!

He had been studying in his mansion, but after receiving the news that Li Chengqian woke up, he threw the book away and left the palace to invite a few "confidants" to go to "Food is the God" to drink!

The princes and children who were previously stopped by their family and were not allowed to visit Li Chengqian were also allowed to visit the East Palace!

When these people seemed to have made an appointment, they all came to the East Palace, Li Chengqian stroked his forehead speechlessly and said, "I said, everyone, you want to see me come one by one, why are you still coming in a group? So many people... I feel a little dizzy when I see it!"

Not only are the princes and children who have been with him in the past come, but even the princes and children who had no friendship before came with gifts!

Of course, Li Chengqian could understand what was going on. The old man was so nervous about him. He left the government behind for several days because he was sick. If he couldn't tell what it meant, then these princes and ministers would have lived in vain!

"Hehe, Your Highness, I have long wanted to see you, but unfortunately my old man doesn't allow him." Du He said with a coquettish smile, "I also brought good things for Your Highness. Do you want to see it?"

"Let's go over there, I'll see you if you have time." Li Chengqian waved his hand and said, "Thank you for coming to see me. When I'm completely cured, I'll invite you to dinner!"

"Your Highness, you are polite!" This is the answer of an unfamiliar person.

"Really? Is it a new delicacy?" This is the answer of those who are familiar with each other!

"Okay, my mother is here these days. I can't bother her. I won't entertain you. Let's go back first... Xia He, go to the warehouse to get some gifts for you brothers and sisters."

...

"Wow, the prince is so generous. He actually gave such a big mirror!"

"No, there are at least hundreds of people like this on the market, right?"

"More than that, the cheapest mirrors sold in the 'Jubaolou' a few days ago are 500 trump card!"

Those who came to visit Li Chengqian for the first time were shocked when they saw Li Chengqian's return gift. They did not expect that Li Chengqian's return gift was actually the "Crystal Realm" that appeared recently in Chang'an, and they were all "full-body mirrors" three feet long and two feet wide!

Just a while ago, a new shop called "Jubaolou" was opened in Chang'an City. This shop does not sell anything else, but only sells various "crystal" products!

The most popular one is the "crystal full-body mirror" that the prince gave to the queen during the winter solstice!

Although the size cannot be compared with the queen's side, it can be fully matched with the title of "full-body mirror"!

"Jubaolou" claims that this kind of mirror is not easy to make and is expensive, so it has very little inventory and can only be sold through auction.

The last auction was on New Year's Eve. A total of twenty mirrors were auctioned, and the lowest transaction price was as high as 500 cents!

The mirrors given by Li Chengqian are as big as those auctioned on that day, and so many are given at one time... The prince is indeed generous and generous!

Du He and others were familiar with Li Chengqian, and those who were involved in the glass business were looking at those people like fools.

It’s not that they know that mirrors are worthless at all, but that after Li Chengqian successfully made the glass, he gave every "shareholder" a mirror that was bigger than those now!

So, in their opinion, those who exclaimed were completely rustic buns!

Li Ke, who followed them out of the East Palace, saw everyone smiling bitterly, and secretly sighed that the eldest brother was indeed a skill, making everyone play around!

...

After sending everyone away, Li Chengqian was not idle because someone came to the door to open again. It was not someone else, but Sun Simiao who had been staying in the East Palace.

"Master Sun, are you done? I'll have so many things I've said. Why are you still pestering me?"

It has been several days since I woke up. Sun Simiao wanted to ask Li Chengqian for advice on "suspending life". Li Chengqian was also curious about the first person in the history of traditional Chinese medicine to fully discuss medical ethics, the first person to advocate the establishment of gynecology and pediatrics, the first leprosy expert, the first method of inventing the method of finger measurement and acupoint selection, the first person to create and draw a color "Mingtang Three People Picture", the first person to promote beauty medicine to the public, and the first person to propose and test wild drugs to turn into family seeds and other legendary "Medical King" was already very curious. So, "Wang Ba Looks at Mung Beans", the two of them immediately got together with interest!

This chat lasts a day and a night, and then...

Then Li Chengqian regretted it, regretting that he had nothing to do and told Sun Simiao some medical knowledge that he had only a little understanding of in the future!

Since the two of them communicated all night, Sun Simiao would definitely come to him every day, and then he would be like a "100,000 Whys", and problems arise one after another, which annoyed Li Chengqian!

"Your Highness, it's really not that I am going to bother you... It's really that Your Highness is too profound. I have many things to understand. I hope Your Highness will give you advice!"

"Okay, okay, I really believe you. I don't know how to ask if you have anything to do. But if you explain it in advance, I may not understand!"

"Your Highness said before that the blood in the human body can be roughly divided into type A, type B, type A, type B, and Qiankun. It takes the same blood type to transfusion for humans. But... how can we distinguish the specific blood type of each person?"

Li Chengqian: “…”

How did he answer this? He is not a professional doctor, so how could he know how to distinguish blood types? And, even if he knows, can it be done with the existing conditions?

But if he doesn't answer Sun Simiao's question, he will keep pestering himself. Because in Sun Simiao's understanding, since Li Chengqian knows the blood type, he must know how to distinguish the blood type.

"I don't know how to determine the specific blood type of each person, but blood type is inherited... that is, the blood type of a child can be judged by the blood type of the parents. For example, the blood type of the parents is all Qiankun type, so the blood type of the child born can only be Qiankun type, and cannot be other blood types; if the parents are A and Qiankun type, the children can only be A or Qiankun type, and cannot be B or A and B..."

Considering that Sun Simiao had never learned English letters and did not know A, B, etc., Li Chengqian directly changed his blood type to A, B and Qiankun, corresponding to A, B and O respectively!

After explaining the basic blood genetic rules, Sun Simiao recorded the paper and pen on the side in detail.

After Li Chengqian finished speaking, Sun Simiao frowned and thought for a moment, and asked another question that gave Li Chengqian a headache.

"Your Highness, why do children's blood types have to match their parents' blood types? What's the reason?"

Li Chengqian scratched his ears and heads and thought for a long time, then said, "This principle... well...is just like a dragon gives birth to a dragon and a phoenix, and a mouse's son can dig holes. Simply put, it is passed down from generation to generation... Anyway, it's almost the same principle. I don't know what's going on. You can study it slowly by yourself!"

The more you explain, Li Chengqian becomes more confused, so I won’t just say it!
