People say that in the spring of the eleventh year of Wanli, there was a tragic situation of the epidemic in Tongzhou, and the Wanli Emperor ordered Chen Shigong, the chief medical officer of Beizhili, to compile a medical knowledge textbook.

This textbook is called "Epidemic Codex", and people generally call it "Wanli Epidemic Code Eleventh Year Edition" because of its year name, because the world knows the four-ocean convention, nothing will be done at one time, and everything will usher in endless improvements after the first edition, until a certain period of time people are generally satisfied with it, and it is the end of a stage.

Even if it is just a lighter made in Beiyang, if the user is not satisfied with something, he can send a letter according to the name of the supervisor on it, and put forward his own opinions - of course, the Beiyang master craftsmen have the final say, but once adopted, the person who made the suggestion will be sent a reward of varying amounts.

Like the Sui Sui hair pre-loading bird gun, it has gone through two to eight years of seven different versions, each version uses parts or interoperable or not, until the eighth year of Wanli is considered to be truly finalized, and only after the finalization in Beiyang, Nanyang, Xuanfu three major weapons bureau gradually expand production capacity.

Even if the production capacity is now expanded, the Ming Dynasty's guards still have not all been equipped with new bird guns, arquebus guns and flintlock bird guns are still parallel, just the old generation of fire guns, fast guns, because the backward arquebus guns are still advanced firearms in the world, and the gap in the overseas domain market is still very large.

"Epidemic Codex" by Chen Shigong, Gong Tingxian, Li Shizhen three famous doctors in the world of medical skills, prescriptions, herbal medicine level determined by the world, is a book according to the existing medical conditions to create a public health and epidemic prevention manual in Fuzhou county and township, mainly used in children, Gongsheng, Juzi and officials at all levels, but also need to be taught by special personnel in Wanli new primary schools in various places.

For the first time, it was proposed that local officials should prepare four levels of precautionary measures according to the intensity of the epidemic, namely A, B, C, and D, and described in detail the specific routes of the spread of the plague and the production and use of medical protective equipment in an illustrated and textual manner.

The book describes the symptoms of 24 infectious diseases that are frequently attacked and 87 diseases that the people suffer from every day, and publishes 227 prescriptions that have been verified and are indeed effective.

The "Epidemic Codex" was read by the emperor and then sent to the provinces as soon as possible, and then the Forbidden City informed the world that in the future, the "Epidemic Codex" will be a compulsory subject for the imperial examination, and the officials who have been in office will also have to study.

For a time, everyone in the officials was in danger, and there was an uproar at home.

However, before this uproar reached the emperor's ears, another incident in the world overshadowed the limelight of the imperial examination to increase the number of medical examination schools...... Master Xu of Songjiang Mansion is no longer good.

Mr. Xu has been ill for a long time, but Mr. Zhang in Beijing is still in good health, and the dietary therapy is not bad, although the disease has not been eradicated, but there is no life-threatening situation, he can eat and sleep, and he can smile often.

I don't know what's going on, since Zhang Juzheng was told by Chen Shigong that he was likely to die from hemorrhoid surgery, the relationship between teachers and students is a little weird.

However, in the end, Xu Jie's serious illness still wrote a letter to Zhang Juzheng, and Zhang Juzheng also asked the court for leave and rushed to Songjiang Mansion to see him, but it was rumored that Zhang Juzheng's face was not happy when he left the house.

What is it that does not believe? Wanli knew that what they said about Zhang Ge Lao didn't believe it, but they didn't believe that Xu Jie's family only had 20,000 acres of fertile land left.

Before his death, Xu Jie gave the court a handbook, and asked the Wanli Emperor to take charge of 20,000 acres of fertile land in the name of the Songjiang Lecture Academy.

Zhang Juzheng actually went to Songjiang for this matter, he actually wanted to remind Xu Jie, it is rumored that the Xu family has 240,000 or 450,000 mu of fertile land, and you will donate 20,000 mu to the emperor.

He is hard-working, he already has tens of thousands of family fortunes in the house, he wants to be famous and profitable, what are he doing with these properties? Donate Tian Quan to the emperor, the emperor is young now, as long as the descendants do not commit adultery, at least they can protect the Xu family for thirty years of peace and wealth.

Xu Jie is also wronged, he put together a total of 30,000 acres of land to plant mulberry cotton, the main income of the old Xu family is the textile business between Songjiang Mansion and Jingshi, Hai Rui Ren Yingtian Governor came to make a noise about his old pavilion, he has already scattered out the field of 10,000 acres, there are 20,000 acres of land left, built a civil university, and finally sent it all to the emperor, you let me take the field out of the half-dead person at this time, how can I take it?

Here's the problem, Zhang Ju is well-intentioned, and he is sure that a large part of the rumors are true.

Xu Jie is also sincere, after his death, the emperor will definitely settle accounts for such a simple matter, and anyone can see that what he said is also true.

What's the problem?

It's out of power.

Power is a strange thing.

After Xu Jiedou defeated Yan Song as the first assistant, he really had so many fields in his name that he couldn't count them, because he didn't know how many fields he had at all, and anyone's fields could be his.

This is called Yoshida, also called dedication.

Officials in the Ming Dynasty had some preferential tax allowances, for example, a Beijing official with a product of 30 stones, and a large number of fields were obviously illegal, but this involved the strange thing of power.

When Xu Jie was the first assistant, who would dare to investigate? What blind person dares to collect taxes?

The most important thing is that even if he receives Xu Jie's head, he can't pay taxes, because those Tian Zhen are not his...... So he could only be scolded by Hai Rui with his head and face.

Hai Rui is not a fool, but with the hope of a better tomorrow in his heart, he went to run Xu Jie's field, Xu Jie obediently scattered Sancheng field, he was transferred to another place, and the matter has actually been solved for Zhang Juzheng.

The solution is that Hai Rui will do Xu Jie's signal, telling the big family who put Tian under Xu Jie's name that Xu Jie's is unreliable.

If it is unreliable, others will naturally take back the field, and Xu Jie's family will really become 20,000 acres of land.

There is no Schrödinger's cat in this world, only Xu Ge's old Tian.

If you don't lose power, you will never know how many fields there are.

This kind of thing, let a county official take a field that exceeds the preferential exemption regulations to touch Hai Rui, can break the bones of his whole family.

But Xu Jie's can't, he is an old man on the left and a bachelor on the right, and Zhang Juzheng has a tattoo on his chest and an image of Emperor Jiajing's ascension to immortals on his back.

Hai Rui couldn't kill him.

Zhang Juzheng's worries were right, a few days after Xu Ge died of illness, Emperor Wanli issued an edict posthumously gifting Xu Jie as a Taishi, nicknamed Wenzhen.

The eunuch sent to announce the decree was not Wang An of the West Factory, but Zhang Whale of the East Factory.
