Zhu Youxiao was quite troubled by this huge number of vassals, and he also knew that he should not be too tough before pacifying Liao and pacifying the She'an Rebellion.

But this does not mean that he did not have the means of gradual reform to revoke the "audit gifts", that is, the farmland; and the privileges, that is, the benefits of salt and iron in the hands of some vassal kings.

All of these are attributed to the state and only the prescribed salary is paid to the vassal state, and they are not allowed to make money by reaching out.

At the same time, Zhu Youjiao also opened a Zongxue, allowing the sons of Zongxue to enter the school, allowing Zongxue to give up his title and salary and change to nationality, and engage in professions such as scholars, farmers, industry and commerce.

Although most of the vassals who want to continue to earn money for nothing, some vassals may see the emperor's malice; or the low-level vassals may feel that their salary cannot support their families, so it is better to get a subsidy from the court and think about other ways out.

Since Emperor Jiajing introduced the "Regulations on Reigns and Vast", he has begun to inherit titles from the vassals, granting land to daily expenses, and even the number of wives and concubines.

However, this famous regulation is still difficult to cure the root cause. The most critical "stand-child" is not mentioned at all. The parasite role of descendants of the vassal kings has not changed at all.

Therefore, although Zhu Youxiao did not implement this most critical item immediately, he instructed the Ministry of Rites to request titles and strictly review the titles, and to block the life of parasites.

If a vassal who cannot get the title is, he will have no way to live without the support of the court. Accepting the arrangements of the court and going to the sect to learn some self-supporting work may be the only choice not to starve to death.

For famous vassals, especially princes and princes, who have relatively rich incomes, Zhu Youxiao has previously borrowed funds to invest their money in bank construction and used dividend income to make up for some of the Dai fortune's expenditures.

Now, Zhu Youxiao is preparing to implement a salary package for the vassal kings. No matter how many children you have or how many relatives you have, the cost will be confirmed.

Every vassal king has many close relatives and royal families. They have no food to eat, so they have to ask for it. It has nothing to do with the court. When the vassal kings are too poor to eat... Well, based on their family background, how many years should they last?

Zhu Youxiao pursed his lips in a sarcasm and asked the palace servants to take his decree to the cabinet to discuss the decision.

The officials' malice towards the vassal state is not only full of malice, but also should have bad intentions. Even for the sake of social stability, it is just a little relaxed.

Zhu Youxiao did not think that such a frog-like suppression would make a certain vassal king rebellious. Since Emperor Yongle reduced the vassal kings, it has been a big deal that rebelled, but it is hard to become a climate.

What's more, the factory guards that Zhu Youxiao relied on and supported were for a good meal? The Ming army that was vigorously formed and transformed was vegetarian? The emperor disciples allocated to various places through martial arts were all veg?

As long as these three things are firmly in your hands, Zhu Youxiao will not be afraid of anyone who can make a comeback.

While thinking, the palace servant came in to report that the female doctor Yang Hanyi came to see him.

Zhu Youxiao thought about it and it was not the day for the harem to be a regular inspection. I wonder what happened to her. But since she came, he had nothing to do and there was no reason for him to disappear.

The palace maid Xuanzhao and the female doctor Yang Hanyi brought Taoyan into the palace to pay homage.

Taoyan is still carrying a basket, but the fat cat is still lazy and doesn't care about anyone.

The little girl has grown taller and is more energetic. She is very relaxed when carrying the basket. I don’t know if she is carrying the cat basket every day to exercise.

Zhu Youxiao Wenyan said: "Yang Qing is flat and is given a seat."

After Yang Hanyi thanked him, he sat on the embroidery pier, pondered for a moment, and then said, "Long live, I heard that you summoned Fu Jiasheng of Ningguo Mansion to enter the palace to plant 'Taiping acne' for the little princess?"

Zhu Youxiao nodded and said, "This is indeed the case."

Yang Hanyi hesitated for a moment and said, "Long live, although the 'Taiping Pox Seedlings' of the Fu family in Ningguofu said that there was no flower planting accident, I think we should be cautious."

There was a saying that acne was invented in the Song Dynasty, but the human acne technology was actually invented during the Longqing period of the Ming Dynasty.

Not only does the "Jinjing Fu of Pox Sciences" clearly state that "the method of vaccinating acne originated in the Longqing period of the Ming Dynasty", Huang Baijia, a son of the Ming Dynasty's remnant Huang Zongxi, also recorded that Fu Shanglin, the great-grandfather of Fu Sichuan, a great-grandfather of Fu Sichuan, was famous for his acne-vesting technique in the early Qing Dynasty.

Zhu Youxiao was very concerned about the health of his children and his women in the harem. In his impression, there was acne-growing technique in ancient China.

Therefore, he asked someone to ask and learned about the "human acne technique" of the Fu family in Ningguofu. Based on his knowledge, he believed that "human acne technique" was completely reliable, although many imperial doctors expressed doubts about it.

At that time, according to the theory of traditional Chinese medicine, smallpox was mainly attributed to fetal toxins, which was called "eating blood and filth in the five internal organs and filth in the life gate". Fetal toxins are the main cause, and external infections such as cold and heat or panic are secondary causes, and the description and nature judgment are relatively chaotic.

In the Ming Dynasty, there was a breakthrough in understanding. Gong Xin's "Ancient and Modern Medical Appreciation" proposed that although acne rash is related to fetal toxins, it may not be caused by the transmission of various diseases.

During the Wanli period, the views included in "Boji Sperm Pox Prescriptions" written by Guo Zizhang had a more accurate view of the cause of smallpox, which is very similar to the description of the mechanism of infection of this virus in modern medical theory.

But closeness does not mean the same, and the medical community as a whole still regards fetal toxins as the main cause. If the theory cannot keep up, it is naturally difficult to promote "human acne technique".

Zhu Youxiao summoned Fu Jiasheng to Beijing. Although his relatives were important, the ultimate goal was to promote them nationwide and form regulations to completely eliminate smallpox in the Ming Dynasty.

Yang Hanyi suggested that one should be cautious, which was naturally out of kindness and was limited by knowledge, so Zhu Youxiao did not blame him.

Although she is not proficient in medicine, it does not prevent Zhu Youxiao from knowing some principles of immunology. She will tell Yang Hanyi that her clinic will also help promote "human acne" in the future.

"Long live, this..." Yang Hanyi was confused by the immunity and antibodies mentioned by the emperor, and opened his eyes widened and asked in confusion: "Is it to let good people contagious, and then he will not get this disease again?"

Zhu Youxiao had to think carefully because he was not a professional doctor, so his wording had to be carefully considered before he could make it clear, "It's not really contagious, but this. After repeated generation and cultivation, the toxicity of this person's acne is already very low, allowing people to produce antibodies but not really get sick."

Yang Hanyi didn't understand the new noun very well, nor did he understand the theory of Long Live, but he didn't know where to ask about it for a while.

Taoyan blinked her big eyes, as if she had figured out some tricks, and bowed and said, "Long live, does this mean that patients who have been cured by smallpox will not have it again?"

Zhu Youxiao's eyes lit up, he pointed Taoyan with his hand and smiled and said, "That's right, that's it. Those who survive by smallpox will not be infected with antibodies in their bodies. This is the principle of human acne. Toxicity does not cause disease, but it will induce reactions from the human body. If antibodies are produced, then smallpox will not be infected in the future."
