"Your Highness, are you interested in medical skills?" While walking towards his courtyard, Sun Simiao asked curiously.

"No, I'm not interested." Li Ke shook his head busily, uncle, don't beat my idea, it's impossible for me to study medicine.

"Then why do you know so much about medicine?" Sun Simiao asked curiously.

"I don't understand. I can't say anything pathology or anything like that. Li Ke shook his head quickly.

Sun Simiao shook his head with a smile, and then he spoke: "The old man has two ideas, Your Highness, can you listen to them?" ”

"Sun Zhenren, please speak." Li Ke said.

"Your Highness, you really don't understand pathology and other knowledge, but Your Highness, you know a lot of medical knowledge, and you can say this knowledge casually, Your Highness, including what you said to Your Majesty about the eldest grandson and empress, and the matter of a woman giving birth, which fully illustrates the two possibilities."

"One, that is, Your Highness, you have studied and understood, that is, Your Highness, you may not have studied pathology and other knowledge in depth, but you have seriously learned all the knowledge of pathology in these general directions, it sounds very contradictory, but it is not incomprehensible, for example, as an emperor, it is very beneficial to understand these." Sun Simiao said with a smile.

"Old Sun, don't talk nonsense, I'm not interested in being the emperor." Li Ke rolled his eyes and said quickly.

"This old man believes that there is only one other possibility, that is, Your Highness, you have lived in a range of medical knowledge, your daily life, your daily experience will be mentioned by people around you about this medical knowledge, although you have never studied it specifically, but under the influence and witness, this knowledge has already penetrated into your knowledge, and you will naturally say it." Sun Simiao said with a smile.

"But as Your Highness, the crown prince, it seems that such an environment does not exist? Unless you're born with a god. ”

Li Ke: "......"

"What, Lao Sun, you are still chattering, can it be that you have learned to read faces? Deduction? Li Ke rolled his eyes and said.

"Hahaha, what does this need, Your Highness, if you are like the old man, you have lived for nearly a hundred years, and most of your life has been in contact with different people and things, Your Highness, when you reach my age, it is natural to see these things." Sun Simiao laughed twice and said.

He didn't dwell on it too much, Li Ke didn't want to say it, so he didn't ask.

Li Ke was a little speechless, there was nothing wrong with saying this, obviously Lao Sun relied on big data, but Sun Simiao's big data was completely a summary of his life experience.

"By the way, please help me send me some pen, ink, paper and inkstone, I need to sort out some of my books, and I also have to trouble His Highness to send someone to my place to help me get some things back." Sun Simiao said.

"No problem." Li Ke nodded, these are trivial things. "Do you want the literate little kids I told you?"

"You don't have to give it all to me, just find some who are interested in studying medicine, you can arrange a few for me, not too much, seven or eight will do." Sun Simiao thought for a while.

"Okay."

sent Sun Simiao back to the courtyard, and then Li Ke explained to Tian Meng again, telling Sun Simiao that he could find Tian Meng for anything, and then Li Ke sent the prepared full version of the "Barefoot Doctor's Manual" over.

These full versions of the "Barefoot Doctor's Handbook" were naturally taken out by Li Ke from the warehouse, and then reprinted, removing all the parts of modern medicine inside, leaving only the pathological knowledge of modern medicine on prevention, disinfection and other basic aspects, and then the knowledge of various important prescriptions. Prevention knowledge such as mosquito control, fly control and rodent control is all there.

And there is a very important version of this, which is not in the version they bought, that is, about how to deliver children and common diseases in children, and common problems in children, Li Ke also referred to some modern knowledge of pediatric medicine.

Li Ke did not leave any knowledge of pure modern Western medicine, firstly, it was unnecessary, and secondly, the popularization of Western medicine was too complicated, which required basic biology, which could not be completed in a day or two.

When he saw so many versions of the "Barefoot Doctor's Handbook", Sun Simiao was also shocked, because the amount of content contained in it far exceeded his imagination, and Sun Simiao, who had traveled all over the Tang Dynasty, knew very well how difficult it was to find out the common diseases of the local people according to local conditions, and the manpower and material resources required were not a base at all.

"Your Highness is kind-hearted, and I am afraid that these books can at least survive hundreds of millions of people, and His Highness's merits are immeasurable." Sun Simiao was a little excited, because he met another person who had the same ideals as him, and the point was that this person had far more than his status and financial resources, especially financial resources, which was very important.

It seems that His Royal Highness's medical knowledge was all read by himself when he was sorting out these books.

"Sun Zhenren is polite, this part is very important, I hope Sun Zhenren can compile it into a separate book, and then fill it with some neglected knowledge." Li Ke pointed to the pregnancy diseases and midwifery medicine section that he took out separately.

Because this is related to the population growth of Datang, and to be honest, if this thing alone can be promoted to the entire Datang, I don't know how many lives can be saved.

"Your Highness, rest assured, the old man will do his best." Sun Simiao's expression was unprecedentedly serious.

"Sun Zhenren, I have one more request." Li Ke said.

"Your Highness, please speak."

"When this book was released in the world, I had to borrow Sun Zhenren's reputation, and I had to say that this book was written by you." Li Ke said.

"This ...... Your Highness, I can't take advantage of this. Sun Simiao paused for a moment and said with some embarrassment.

"Sun Zhenren, you should know better than me that your authority in medicine and your reputation in the world can be issued in your name, so that the people of the world can believe it, and everyone can follow the methods in the book without doubt. Li Ke said helplessly.

"Your Highness, you underestimate your status in the hearts of the people of the world." Sun Simiao smiled and shook his head.

"Anyway, it's decided, without your endorsement, I can't promote this book." Li Ke shrugged his shoulders.

"The matter...... I can agree for the time being, but when the time comes, I will talk to Your Majesty and then I will have to read this book in its entirety, and then I will sort it out and return it to Your Highness. Sun Simiao thought for a while.

"Yes." Li Ke thought about it, and then agreed.

After chatting with Sun Simiao, the other party drove people directly, he said that he wanted to read the book quickly, and Li Ke left some maids and left.

Back to the square in front of the door, the temporary pot stove has been built, a big iron pot is placed here, Li Ke directly began to direct people to boil syrup here, when the syrup boiled out of the "goo-goo-goo" foam began to become smaller, Li Ke asked people to stick strings of good hawthorn on the outside foam.

You don't need to go deep into the pot, it is enough to dip the sugar bubbles on the outside in a circle, and after dipping them around, put them aside and wait for the sugar to cool.

Jinyang and these little guys can't wait for a long time, if it weren't for Li Ke saying that it is not delicious now, it is estimated that they would have started a long time ago.

Seeing Jinyang and them playing there, Li Ke took out a roasted sweet potato that had just been peeled and handed a few to Jinyang.

"Woo...... Delicious...... Third brother, what is this? Jin Yang looked at the reddish-brown sweet potato in his hand curiously, it was too sweet and delicious.

"Sweet potato, Dad, you can taste it." Li Ke gave Li Shimin another piece, and they each broke a piece.

After Li Shimin and the others had eaten, Li Shimin nodded: "This thing is good, you can send some to the palace at that time." ”

"Dad, you know what?" Li Ke suddenly said with a smile.

"What?" Li Shimin was a little puzzled.

"The sweet potatoes in your hands and the potatoes in your hands are two grains, and the yield is 25 stone per mu." Li Ke said with a grin.

Li Chengqian, who was next to "poof......", directly squirted out the tea in his mouth, and Li Shimin was even more startled, the sweet potato he was holding in both hands fell directly without catching it, and fell on his dragon robe, and a large piece of sweet potato immediately stuck to the clean dragon robe.

The eldest grandson queen and the others were also a little dumbfounded, and subconsciously looked over.

"What did you say?!" Li Shimin didn't care about the stains on his body, picked up the sweet potatoes on his body, got up from the chair and asked with his eyes glaring.

"I said, this thing yields 25 stones per mu." Li Ke said with a grin.

The yield per mu is 25 stones!! Hearing this number, everyone present was frightened, and they didn't know how to describe their feelings.

Changle and the others are somewhat better, but they also know what this number means.

And Li Shimin and Li Chengqian looked at Li Ke in a daze as if they were stupid.

"Especially this one." Li Ke picked up a roasted potato, "This thing can be eaten as a meal, it will not cause any harm to the human body, but it is also very nutritious, its yield per mu can reach about 25 stones, and it is very easy to preserve, and there is no problem in keeping it for a winter." ”

"You ......" Li Shimin didn't know what to say for a while, such an important thing, shouldn't you say it earlier?! You're ......

"Hehe, I'm not thinking about Li Tai just being dealing with government affairs, let him sort out the list of officials in charge of agriculture in various prefectures in the world, and then sort out some suitable land, and by the way, formulate a reasonable way to promote new crops, so as not to be affected by your father in the future." Li Ke laughed twice.

Li Shimin: "......" He was a little speechless, am I talking about this? Do I care about the people who are affected? Besides, can Li Tai do this task you are talking about? Sounds simple, but this works...... It is necessary for the three provinces to deal with it jointly.
