After I got into the drama, I led the plot astray

I felt that Fan Chunlai had gone crazy, and kept saying, "Doctor Fan, let me teach you how to prepare this ointment."

When Fan Chunlai heard this, his eyes lit up. He quickly and carefully folded the prescription and put it into his sleeve. He bowed to me and said, "I will listen to your instructions, sir."

It is very simple to prepare this ointment, but the raw materials are not sufficient, such as lack of almond oil or rose oil, and the ointment is not lubricated enough. But it doesn’t matter, as long as it works well.

I was preparing the medicine when Zhang San and Li Si walked in. When they saw Fan Chunlai there, they didn't say anything and just watched me prepare the medicine quietly.

After I prepared the medicine and sent Fan Chunlai away, Zhang San said, "Second Young Master, do you have something to talk to me about?"

I nodded and pointed to the jar behind the door and said, "You two take this jar back to the mansion and give it to Su Bowen's parents. Tell them that the jar contains Su Bowen's bones. If they want to go back to the countryside to bury Su Bowen, you can give them some money to go back to the countryside. If they don't want to go back to the countryside and want to find a piece of land in the capital to bury the bones, you can help them get it done."

Zhang San took a look at the jar and said, "Now the people of the capital are forbidden to go out. We need a pass to go back."

Is the ban so strict? Can't go out without a warrant?

I asked in confusion, "Where did the warrant come from?"

Zhang San said: "All warrants are issued by the palace. As for which department issued them, I don't know."

I thought about it. When Zhao Zhen left, he left thirty cavalrymen to guard here. These thirty cavalrymen had to carry out their duties everywhere, so they definitely had warrants.

So I took Zhang San and Li Si out.

The thirty horsemen took over the job of the nine guards and took turns guarding the small courtyard. They kept the entire courtyard like an iron barrel, and not even a fly could fly in.

The cavalry had strict discipline and were serious about their words. When they stood guard, they were like a pin that stabilized the sea, motionless. They wore uniform black armor and a black cloak, looking majestic and intimidating.

Qin Feng and his eight guards were using a manpower-pulled cart to pull the dead cows. When they passed by the cavalry, they had to take a detour and did not dare to get close to them.

There was a cavalryman standing outside my house. Zhao Zhenyuan had specifically assigned him to protect me.

I walked straight towards him, while Zhang San and Li Si followed me from a distance, not daring to get close to them.

A cavalryman is a cavalryman. Even if I walked up to him, he would still stand there as steady as an old dog, without even glancing at me.

I asked, "Do you all have a warrant?"

Tieqi didn't know whether he should answer my question. He thought for a long time before answering, "Yes!"

I asked, "Can you lend me two so I can go into town and do some work?"

Brother Tieqi was stumped and didn't dare to say a word for a long time.

I had no choice but to say, "Even if you lend me your pass, I will let them bring my token into the city. If anyone tries to stop them, I will just say they are doing something for me and will not implicate you."

After hearing this, the cavalryman reluctantly took out a black token from his lapel and handed it to me, saying, "General Zhao has ordered that this token cannot be lent out at will. If it is lent out or lost, it will be dealt with according to military orders. I hope you will keep it properly and return it to me immediately after the task is completed. Don't lose it, otherwise my life will be over."

I took the token and saw a line of numbers "Five Thousand Seven Hundred and Eighty-One" on the top, with only four words "Pass Token" in the middle, and Zheng Xian's reign title below the token.

What a jerk this Zheng Xian is. He issued so many pass tokens but didn’t even give me one. That’s too much!

I secretly complained in my heart, asked another cavalryman for a token, and then handed it to Zhang San together with my golden token.

It was also the first time that Zhang San saw my token. Although it was not an identity plate, it was more important than an identity plate. Anyone who saw it had to kneel down and salute me, and respectfully call me "Lord Zhao".

Zhang San took my token with some trepidation and said, "Second Master, your token feels a little hot in my hand."

I said unhappily, "Let's go quickly, or it will be hard to walk on the road when it gets dark."

Zhang San put all the tokens into his lapel, then walked to the door, picked up the jar and walked out quickly.

Their horses were kept in a cave on the mountain. The cave was very big and was perfect for storing horses.

After Zhang San left, I gathered Fan Chunlai, the three doctors he brought with him, and two imperial physicians, and began to teach them acupuncture.

Acupuncture is not difficult. They learned it after just a few tries. But it is not easy to become proficient. So I asked them to practice acupuncture with radishes. They obediently took a radish each and started learning acupuncture seriously.

I went to see the remaining twelve cows. Several of them had already grown pustules, and the remaining ones also showed symptoms, but the pustules had not yet grown out. They should grow out by tomorrow at the latest.

After Fan Chunlai and the others had almost finished practicing acupuncture, I asked them to put on masks and gloves, put on overcoats, and went to the cowshed to teach them how to collect bovine pus fluid with a syringe.

These people were all experienced doctors. Although extracting pus was a bit disgusting, they still followed me professionally and learned how to extract pus with a syringe.

The bovine pus cell fluid is stored in a highly disinfected bamboo tube to prevent secondary contamination.

That night, I injected myself with bovine pus spore fluid.

The pus cell fluid was not diluted or purified, and I didn't know how much to use, so I estimated the amount and injected it into my arm. After the injection, a lump quickly appeared on my arm. The lump was red, swollen, itchy and painful, but I couldn't scratch it with my hands, let alone apply medicine. When it broke the skin and scabbed, it meant that the vaccination was successful.

Five doctors watched the entire process. They finally understood what "vaccination" was all about and what constitutes a successful vaccination.

After they have learned it, they will teach it to more doctors. Otherwise, even if I have three heads and six arms, I will not be able to cope with a nationwide epidemic outbreak.

After the injection, I had a reaction that night, a low fever, a headache, and bone pain, but it was not very serious. I recorded these reactions in detail, and I will give them to Fan Chunlai and others when the time comes, so that they can have a document to check no matter what problems they encounter in the future.

The next day, I did not have a high fever. In fact, after dinner, all the symptoms had disappeared. A scab had successfully formed on the needle hole on my arm, indicating that my vaccination was successful.

This vaccine is toxic and has many other unstable factors, but in ancient times, it was the best way to treat smallpox. Even if someone died from an allergic reaction to the vaccine, this method should be fully promoted. After all, the lives of a few people are far less important than the lives of the majority.
