In fact, Li Ke is quite interested in the Dengzhou Yu family now. According to what Yu Huatian said, the Dengzhou Yu family should have a lot of books.

So he smiled and asked Yu Huatian: "I don't know why the Dengzhou Yu family has Hua Tuo's codex?" I wonder if there are other unique books besides Hua Tuo's Codex? ”

Yu Huatian said to Li Ke without hesitation: "Lord Wang, there is a library in the Yu family in Dengzhou, and there are countless books in the library. But most of them are just ordinary books. ”

"But on the ground floor of the library, there is a secret room. The existence of this secret room is known only to the head of the Yu family, and I also discovered it by accident. ”

"There are many unique books in the secret room, including not only the Hua Tuo Codex, but also dozens of books such as the Yellow Emperor's Neijing and the Green Capsule Book."

"A little-known Dengzhou Yu family has dozens of ancient books. I don't know what kind of background this Dengzhou Yu family has? Li Ke opened his mouth and asked Yuhuatian.

"Don't hide it from the prince, the ancestor of the Yu family was not surnamed Yu, and the surname Yu was changed later. In order to escape the pursuit of the imperial court. Yuhuatian opened his mouth and said to Li Ke.

"Then I don't know what the original surname of the Yu family was? Why was he hunted down by the imperial court? Li Ke asked inquiringly.

"The original surname of the Yu family was Wu, and he was originally a jailer of Wei during the Three Kingdoms period." Yuhuatian opened his mouth to Li Ke.

I heard Yu Huatian say that his ancestor's surname was Wu, and he was a jailer of Wei. This can't help but make Li Ke think of a person, that is, Wu Prison who burned the green capsule book back then.

So he said to Yu Huatian: "If this king is not mistaken, your ancestor should be the Wu prison who took care of Hua Tuo back then, right?" ”

"The prince is really knowledgeable, and he even knows the things of the ancestors." Yu Huatian was also shocked when he heard Li Ke's words, after all, he didn't expect Li Ke to know about it.

"The historical records are not entirely correct, it seems that your ancestors did not burn the green capsule book back then. And he also got Hua Tuo's true inheritance. Li Ke looked at Yuhuatian and asked.

"What the prince said is right. All the books collected by Hua Tuo's divine doctor were donated to the ancestors. These books became the foundation of the Yu family's heritage. Yu Huatian nodded and said.

"It seems that this king is going to take time to go to Dengzhou, I hope Yu Buqun has not discovered the dark room of His Excellency." Li Ke said bluntly.

"Don't worry, the dark room is very tight. If it hadn't been for the subordinates who accidentally discovered that their father had opened the dark room, they would not have found out anyway. ”

"Now that my subordinates have become eunuchs, even if they have those ancient books, they can't pass them on anymore. These ancient books can only be passed on by the prince. Yuhuatian opened his mouth and said to Li Ke.

Li Ke nodded and said: "Books should be for the world to learn, and storing them in a secret room is different from Qin Shi Huang's burning of books and Confucianism." ”

"If these books are still stored in the dark room of the Yu family, this king will definitely let them see the light of day again. so as not to disappoint the efforts of our ancestors. ”

Just as Li Ke was chatting with Yuhuatian, those imperial doctors returned to the study again. And said to Li Ke: "Lord Wang, we came to a conclusion after checking the books. ”

"The reason for the instability of the prince's blood should be caused by the wind and cold after being frightened that day. So I've already prescribed a prescription, as long as the prince takes the medicine on time. ”

"It is worthy of the holy hand of the Chinese medicine of the Tai Hospital, and in such a short period of time, he has found the key to the king's illness."

"This king will report this matter to his father, so that his father can reward all the imperial doctors." Li Ke said happily.

However, Li Ke had another statement in his heart, that is, the gang standing in front of him were all quacks. I don't know how many people in the palace are terminally ill and incurable because of their perfunctory work.

But on second thought, you can't blame these imperial doctors. Once those royals in the palace became seriously ill. Needless to say, simple diseases are naturally not to be said, if they are some incurable diseases, then it will be difficult for these doctors.

If the Tai Hospital is helpless, it will definitely make the emperor Longyan angry. When the time comes, it is impossible to say who will be unlucky because of this.

So over time, they have an unspoken rule of their own. That is, when the cause cannot be identified, some drugs will be prescribed in a unified manner to treat the symptoms but not the root cause.

This not only shows that the imperial doctor of the hospital is skilled, but also exempts him from being punished by the emperor. As for the final death, they will also find many reasons to shirk responsibility.

This is how the imperial physician of the DPRK and China protects himself. Of course, it's not just the Tai Hospital that has this unspoken rule. This is also the case in the three provinces and six ministries of the DPRK and China.

Therefore, Li Ke naturally didn't care about this matter, and just took advantage of this matter to get off the donkey. lest those who have a heart know the truth and do it unfavorable to themselves.

Yuhuatian on the side naturally knew that these quacks were perfunctory again. However, Yu Huatian didn't say anything, but said: "Since the prince's is no longer in the way, then we will talk about our affairs." ”

After finishing speaking, he bowed to Li Ke and retired, and left Li Ke's study with several doctors from the Tai Hospital.

……

In the next few days, Li Ke took Li Chengqian and Cheng Yanjin to visit various places of interest in Jinan. It can be regarded as letting everyone not come to Qizhou in vain.

And Li Chengqian naturally thought of a way to deal with his errand. That is, he pretended to catch Shan Ailian's comrade and handed over Shan Dao Zhen Wuhua to Li Ke.

In this way, Li Chengqian's trip can be regarded as a successful conclusion. Before leaving, he greeted Li Ke again, and brought a Quyuan plough back to Chang'an City.

After sending Li Chengqian away, Li Ke was dragged to the cotton field by Kong Jingrou again. Began Li Ke's career as a cotton planter. From the beginning of the year to the time of the single road, Li Ke was not left.

However, Li Ke was not in a hurry at this time, so he handed over Shan Daozhen to Shan Ailian first. Reunite their brother and sister.

……

Nowadays, the curved plow has begun to be popularized in large numbers, after all, the process of the curved plow is not very complicated. As long as there is some carpenter with some craftsmanship, it can be made.

So now when you look at the people who are ploughing the fields, there are few people who are using the straight plow. They have all been replaced with more useful curved plows.

But there is another thing that stumps the people, that is, the sky is not beautiful, and there has not been a drop of rain since the beginning of spring ploughing. If this continues, the seed will probably die in the ground.

So the people began to use buckets to draw water from the river to water the fields, but the effect was too slow. It can be said that the drought is just a drop in the bucket.

Although there are rickshaws that help carry water up the river, they are too labor-intensive and can carry a limited amount of water.
