Zhang Zhou didn't say too much to Zhu Feng that day, because many things were also uncertain factors for Zhang Zhou, and it was useless to say more.

The sky was darkening, and Zhu Feng was leaving.

When Zhang Zhou sent him out, Zhu Feng turned around to look at the chicken cage in three steps, it seemed that the yard was full of things that made him feel novel, that is, the cage of chickens, Zhang Zhou also wondered in his heart, it seems that the second son of the national family has the potential to open a chicken farm.

"Husband, who is that son? Look at his clothes, not only rich, but also expensive. “

Zhu Feng left, and the flowing water mats at the door also dispersed one after another, Zhang Zhou returned to the courtyard to cover the door, while Jiang Pingyu came to inquire about her husband.

Zhang Zhoudao: "He is Zhu Feng, the second son of Cheng Guogong, who is about to go to the capital to take over the affairs of Nanjing Jinyi Wei, and before leaving, he wants me to help him take care of the rice and grain business." ”

For others, this may be an honor, but Jiang Pingyu was not happy to hear it: "The husband is now a master, so it's better not to take such an errand." ”

In the eyes of a traditional woman like Jiang Pingyu, if she is promoted in the examination and has a social status, she can get rid of business.

Zhang Zhou smiled: "It's nothing, now I want to do another thing with him, it is said that there is an epidemic in Yangzhou City on the other side, I may have to leave home first tonight, and come back very late tomorrow." ”

"Huh?"

Jiang Pingyu was surprised.

Today, my husband just passed the exam, and he is about to go out?

Zhang Zhou said: "Madam, while the city gate is not closed, I want to go out of the city quickly, I can't explain it to you, but you just have to believe that I do everything for this family." ”

"Nafu-kun...... Come back early. ”

Jiang Pingyu's eyes were a little reluctant.

But she still hurried to pack her husband's things.

Han Qing on the side was busy for a long time, and was sitting in front of the stove to rest at this time, knowing that Zhang Zhou was going out of the city, he said curiously: "Madam, Aunt Lin has washed the bath and will send it later." ”

said, his face was still a little shy.

Obviously, their sisters are now convenient, and Zhang Zhou has also taken the exam to understand the yuan, and the family conditions have been improved.

But at this time, Zhang Zhou still has the heart to go out?

Jiang Pingyu said: "The husband has something big to do, and we have to obey him." ”

Zhang Zhou smiled and brought the second daughter over, and said with a little pride: "Yes, there is no rush to do things, wait for me to come back tomorrow!" ”

……

……

When Zhang Zhou took Liu Gui out of the city, he was also thinking that he was crazy.

In Nanjing, less than a month after the incident, he actually wanted to treat the emperor's daughter? Or is smallpox still going to be cured?

Alas!

Zhang Zhou sat in the hired carriage and couldn't help but sigh when he saw the city gate in sight.

Liu Gui said: "Master Zhang, you have become a lifting master, what are you worried about?" ”

"Annoying! There's a lot to worry about! ”

Zhang Zhou knew very well that in any era, smallpox can only be prevented and not cured.

Whether it is in China, or looking at the whole world, if you have smallpox, you have to resign yourself to fate, young and middle-aged people are okay to get sick, and their immunity is relatively strong, if the elderly and children with low immunity get it, in the case of backward medical conditions and even no antipyretics, the mortality rate is close to fifty percent, it can be said that half of the people can live, and half of the people will die.

Even if they live, they will have pockmarks left on their faces, and some even have rotten noses, leaving only two nostrils.

The only way is to get pox.

The history of human pox in China is very early, but the effect is not ideal.

But it would be hundreds of years before cowpox was discovered and widely used to control smallpox.

The little princess Zhu Xiurong obviously did not run out of the palace and was infected, but from the outbreak and infection of smallpox within the palace, and from the palace attendants who took care of Zhu Xiurong.

The incubation period of smallpox is 10 to 12 days on average, and if a person is vaccinated with a smallpox patient within two days of blood vaccination, the vaccinia will have a rapid blood reaction, and immunity to smallpox can be basically formed.

If it is three to seven days, the chance of developing antibody immunity is high, and most young adults do not have smallpox.

If the pox is planted in 8 to 10 days, the onset will be mild.

If you plant pox for more than ten days, it will basically be ineffective.

For people with low immunity, such as four-year-old children like Zhu Xiurong, the time may be earlier.

With thousands of years of experience in the prevention and control of smallpox in China, especially the palace, the isolation of people around the person who has smallpox will be relatively in place, and Zhu Xiurong was infected with smallpox in history, but did not infect Zhu Youzhi and his wife and Zhu Houzhao, which also shows that in this smallpox outbreak, the palace prevention and control work is relatively in place, at least Zhu Xiurong was isolated in advance.

Zhang Zhou's plan is to beat this time difference.

If he can use a clever influence to plant pox in about seven days after Zhu Xiurong contacts the patient, then Zhu Xiurong will still get sick, but the symptoms will be mild and not fatal, and Zhang Zhou can achieve the best results with a pox experiment done by the daughter of the royal family.

The most difficult thing for him now is to find a cow with smallpox, and it must be before Zhu Feng goes north.

If he can't find it before he comes to Japan, then he doesn't need to mention it to Zhu Feng, if he finds it, Zhu Feng doesn't believe him, then he won't be reluctant.

Of course, even if he found it, he couldn't tell Zhu Feng that this was a pustule after the cow got sick, but would say that this was a "miracle drug", in order to ensure that this magic medicine was harmless, Zhang Zhou also wanted to do a field test with Zhu Feng.

At the same time, this is also a layer of protection that Zhang Zhou has made for his family, who made the epidemic likely to spread to Nanjing City soon?

……

……

The next day was the feast of deer.

On the same day, the Nanjing Gongyuan was very lively, with internal and external curtain officials, plus the people raised in this township examination, as well as the Xuezheng teachings learned from the county school, Ying Tianfu officials and others...... There are hundreds of people.

Originally, the most eye-catching person that day was, of course, Zhang Zhou, who was Xie Yuan in the Jiangnan Township Examination.

But it's a pity...... Zhang Zhou went out of the city overnight yesterday to look for sick cattle, and he didn't come to participate in this Luming banquet at all.

Daming's deer banquet is not necessary to participate, the township examination is over, after all, there is a period of time to the list, many candidates go back to their hometowns after the exam, after all, staying in Nanjing and waiting for an ethereal result is very hard, and not every candidate can live in the provincial capital for a long time without working.

Also, it is the same in my hometown and waiting for the list to be released, which will lead to the Luming banquet on the second day after the list is released, there are always many people who can't come because of various factors.

But people like Zhang Zhou, who is a student in Nanjing City and also lives in Nanjing City, do not come to participate in the Luming Banquet, which makes people feel unusual.

"Jizhi, I heard that Zhang Bingkuan didn't come?" Liu Ji also went out to drink two rounds of wine with the people of Ying Tianfu first, and then returned to the table prepared for the exam, and saw Wang Wei sitting there quietly, so he couldn't help but ask.

Wang Wei glanced back, and the table behind him was the table prepared for the top ten in the township test.

A lonely figure happened to have his back to Wang Wei.

Wang Wei said: "Since Xie Yuan didn't come, let Yayuan Bohu come over, raise people on behalf of the people, and toast the people present!" ”

That lonely back is Tang Yin, who should have solved the yuan in this township examination, but under the butterfly effect caused by Zhang Zhou, he ranked second.
