Zhenguan Xiaoxian Wang Li Shen Li Shimin

In March, Li Shen was finally released. The compound crossbow and compound bow he developed have been successful. Although they are far behind those of later generations, they are already much improved for this era. The steel balls used for pulleys are produced in large quantities and the same size can be found from the middle. There are definitely flaws in the quality.

Just when Li Shen was about to leave seclusion, he received bad news. An epidemic occurred in Zezhou (today's Jincheng City, Shanxi Province). Li Tang raised troops from Taiyuan, Shanxi to conquer the world. Therefore, Shanxi had a very prominent position in the political map of the Tang Dynasty and was regarded as the "land of dragon prosperity". The occurrence of diseases here was no small matter. Moreover, Shanxi is close to Chang'an, the political, economic and cultural center. If we are not careful, the epidemic is in danger of approaching the capital.

Li Shimin ordered the dispatch of imperial medical officers to carry medical supplies to various states and counties to treat infected people. The imperial government directly dispatched disease prevention and control, so that the source of infection could be quickly cut off at the very beginning of the epidemic. The Tang Dynasty had relatively rich experience in epidemic diseases. Know how to set up separate medical institutions to isolate and intensively treat sick people. Many temples are used as shelter and treatment places; bury the remains of people who died due to the epidemic in a timely manner to avoid reinfection of the epidemic; allocate food to relieve people in epidemic areas , reduce or reduce local and even national taxes, vigorously combat witchcraft and superstition, etc.

Li Shen also received news from the palace. Let the clan members of each government not go out as much as possible. Avoid external sources of infection. The people of Chang'an were nervous for a while. Li Shen recruited various officials from the palace. Business king Hongfu, civil servant Wang Xuance, military general Xue Rengui, and palace steward Wei Fugui.

"Xuan Ce, do you have any news about what kind of disease it is?" Li Shen was still worried about unknown things.

"Your Majesty, I heard it was smallpox. Many people have developed maculopapular rash, fever, pain and other symptoms. Your Majesty has sent palace medical officers to carry medical supplies to various states and counties to treat sick people. However, the death rate from smallpox is extremely high. Mainly It's still prevention and control." Wang Xuance has already received the news.

"Smallpox?" Li Shen began to think. Later generations have eliminated the smallpox virus. The method is also very simple, just vaccinate against cowpox. The earliest heard was that cows would develop chickenpox after being infected with smallpox. Cut open the human skin and smear the liquid from chicken pox on the cow. Later, I started using the simple and effective method of injection.

"Xuance, send someone to Zezhou to find some cows that have smallpox. It needs to be faster, and it's best to find people who have had smallpox before. As long as you have had smallpox, you won't be infected in the future. ." Li Shen wanted to see if cowpox was effective.

"And Uncle Fugui, please arrange for people to prepare food. If there are people fleeing, we will give porridge at the gate of the city."

"It's the prince." Wei Fugui took the order and went out. Everyone started to take action.

Half a month later, Wang Xuance informed Li Shen to bring back three infected cows from Zezhou. Li Shen asked someone to bring the cow to the military camp. Pick up the tools and lead the people straight to the military camp.

Dongshan Military Camp is now known to nearby villages. The entire Dongshan belongs to Prince Ji's Mansion. No strangers allowed to enter or hunt. When Li Shen arrived, the cattle had already been isolated and processed. Li Shen and Xue Rengui came to the barracks. He needed some experimental subjects.

Although the method of vaccination is very simple. But still want to be safe. Li Shen asked people to find some craftsmen who had been robbed before. After a while, everyone arrived.

In the frightened eyes of the craftsmen, Li Shen said: "I'm calling you here this time because I want you to do something voluntarily. I'm going to experiment to treat a disease. It will take a few people to verify it. But there is a certain risk.

Which of you volunteers to do the experiment? After success, I promise to let your family leave. Even if it fails. I will also ensure that your family has land to survive with me. Come forward if you are willing." After Li Shen finished speaking, he looked at them.

There are 30 people in total. You look at me and I look at you. All very hesitant. In the end, a total of six people came out and were willing to give it a try.

Li Shen didn't waste any time and led people to the quarantine area. The person who brought the cow back was named Li Erwa. It was a person from Huangzhuang who had smallpox when he was a child. Fortunately, he survived. Li Shen told Li Erwa to make small cuts on the arms of several people, not too deep. Just suck out the pus from the blisters on the cow with a needle and inject it into the mouth.

Li Erwa followed Li Shen's method and first disinfected the props with alcohol. Then a small cut was made on the arms of six people. Inject the pus into it. After everything was done, several people were isolated in the isolation area, and someone sent meals every day. Because there are no masks. Li Shen has been conducting remotely. He didn't want to die young. (In order not to be arrogant, let’s talk about it. There are six knives used to make the cuts. Do not touch the wound when injecting pus. Just stick it in. This is okay.)

The next day Li Erwa observed the situation of the six people. Six people developed symptoms to varying degrees. Some have acne. Have a fever. On the third day, when Li Shen went to observe the situation again, he found that six people had recovered.

Li Shen is very tall, which means success. In fact, growing beans is very simple. China was the first to use this method. It was later introduced abroad. Li Shen and the people in the palace also began to vaccinate, but Li Shen only injected the skin directly with a needle. He didn't want to get stabbed.

Three days later, everyone in Prince Ji's mansion had finished planting beans. Li Shen asked Wang Xuance to buy another twenty cows and send them to the quarantine area to allow them to be infected naturally. Then he ordered all Xue Rengui's guards to take turns planting beans, and to train 1000 people to learn to grow beans.

Ganlu Palace: "Your Majesty, King Ji has brought a cow into the palace." A guard came in and reported to Li Shimin

"Go on, you know." Li Shimin said without hesitation. I wonder if this guard wants to show his face in front of me. Li Shen's entry into the palace is nothing new. But he soon grasped the point again.

"Wait a minute, what did you say Prince Ji brought into the palace?" Li Shimin asked uncertainly.

"Your Majesty, it's a cow. And he also asked people to keep a distance of ten feet from each other." The guard replied.

"A cow? You said Li Shen brought in a cow? Why did he bring the cow? Do you want to eat the cow? If word spreads about cow-eating in the palace, it will be fine. Eating cows is against the law. When the time comes, follow the example."

"Let's go to Daji Hall." Li Shimin couldn't sit still.

Li Shen took the sick cow to plant beans for Concubine Wei and the others. He also didn't know how long it would take for the germs to become ineffective after leaving the cow's body. So we can only adopt stupid methods to plant on site. Li Shen moved the cow to the entrance of Daji Palace and asked the palace guards to guard it from ten meters away to keep others away.

After Li Shen entered Daji Hall, he summoned his mother and sister. "My dear concubine, I came here today to vaccinate you and your sister with pox. Once you have the pox, you won't get smallpox again."

"You will never get smallpox again?" Li Mengjiang asked in surprise.

"Yes, sister, haven't you read the medical books that say that people who have had smallpox will never get smallpox again." Li Shen looked at Li Mengjiang and explained.

"Then we have to get through it before we can get rid of it. Are you going to let us get it once? This is very dangerous." said Concubine Wei.

"Concubine, it's not dangerous. Everyone in my house has been planted. It has been seven days. Don't worry, it will be fine in three days." Li Shen said and took Concubine Wei out and asked Li Mengjiang to wait.

When he arrived at the door, Li Shen saw many guards in the distance, and Li Shimin stood in the middle. When Li Shimin came, he heard the guards saying that he was not allowed to come near. He also knew that there must be a reason for Li Shen's refusal. So just wait here.

Li Shen went over to greet them and said, "Aye, I'm here to vaccinate my concubine and sister with cowpox. After being vaccinated with cowpox, you won't get smallpox."

"What kind of pox are you getting? You won't get smallpox in the future? Li Shen, are you sure what you said is true?" Li Shimin's eyes lit up after hearing this.
