After all eight people were injected with cowpox, they all looked at Yu Zhi fucking nervously, not knowing what would happen next.

Wei Si is a death row prisoner. His wife committed adultery with someone else and went to the door to kill others' family. Later, he surrendered to the yamen and was sentenced to execution after the autumn. According to the days, he would have to go to the execution ground at most three months, but unexpectedly, two yamen runners suddenly came today and took him out of the jail.

Since pleading guilty, he has never walked out of the death row. He knows that there are only two ways for death row prisoners to leave the death row, either die in the death row or be sent out to the execution ground.

"It's still summer now, what are you going to do?"

Wei Si asked nervously. After killing someone, he was already determined to die, but during the period when he was waiting for death in the death cell, he was less and less willing to die.

"I don't know, don't ask, just follow me!" The yamen runner said a few words in a cold voice, then took him out of the Chang'an County Prison, and then saw a team of soldiers standing at the door. After the yamen runner handed him to the sergeant, he was stuffed into a carriage. Wei Si swore that this was his first time riding a carriage, but it was not very comfortable.

Soon the carriage stopped and he saw that he was taken to a mansion. He didn't recognize any of the words on it. He didn't recognize the words. Many people were illiterate.

The mansion is very luxurious. This is the most luxurious mansion Wei Si has ever seen, and it is larger than the mansion Huang Yuanwai in their yard.

"Get in!"

The soldiers pushed Wei Si into the mansion. After about a few minutes, other carriages rushed over one after another. With him, eight people were gathered in an open space.

Immediately afterwards, a young man in gorgeous clothes stood in front of him and told him that as long as he cooperated, he would be exempted from the death penalty. Wei Si did not believe this, and Tang Lu was very strict, so he had never seen anyone escape. He heard that even if the prince broke the law, he would be dealt with, but now this young man.

But Wei Si soon believed it because the young man told him that he was the crown prince of the current dynasty. He had heard of the crown prince and was a very powerful person. As for how old the crown prince was, he didn't know. The emperor's son said that he would not kill him, so he shouldn't kill him, right? Wei Si was secretly happy.

However, this secret joy lasted only a few minutes before it disappeared, because he saw a doctor pulling a cow over and then busying himself on the cow, then cut a hole in the arm of a death row prisoner who was like him not far away, and then poured something on it.

Fear, Wei Si was very scared. He didn't know what he was doing. But he felt that it was definitely not a good thing. Now he wanted to return to the cell. He felt that the cell was safer than here. He knew that there was no free cake in the world. He committed a punishment. Being able to forgive his crimes would definitely be more dangerous than beheading.

But struggling had no effect. The two strong soldiers grabbed Wei Si's arm tightly with their hands like pliers. Wei Si could not move at all. Then the doctor came to Wei Si and, like the previous few people, cut a hole in his arm, and then dripped an unknown thing into his wound.

It was not very painful, Wei Si breathed a long sigh of relief in his heart. After all the rest of the people were planted, Wei Si was taken away and taken to a small room, living alone, with darkness around him, and only some light that shone through the gap made him feel that he was still alive.

On the first day, there was no feeling. Someone brought food on time. These foods were much better than the death row, and even better than what he had eaten at home before. There were meat, vegetables, and the amount was even greater. If it weren't for knowing that he was a death row prisoner, Wei Si would even have the urge to live here all the time, at least, he would not have to worry about food and clothing here, and he had a good meal.

However, by the next day, Wei Si felt cold and hot all over, and his body was constantly squeezing, sometimes cold and sometimes hot. Wei Si felt that he might be dying, and he might be dying in great pain.

After Wei Si's high fever lasted for two days, Wei Si's condition began to subside. On the fourth day, his health had improved. Wei Si thought he had completely survived, but it was not over. After his health improved, he was taken out of the city and locked up with a patient.

"This person has smallpox!"

Wei Si looked at the patient lying on the hospital bed and swallowed. He had been an apprentice in the pharmacy for two years, and he could still recognize some obvious symptoms.

"smallpox!"

The other seven people looked at the person lying on the hospital bed and were frightened to take two steps back. The more fierce prisoner took a deep breath and hammered the hammers hard: "This person has smallpox, we want to go out, we want to go out!"

The sound was loud, but no one responded. The person closest to them was more than ten meters away, wearing thick protective clothing, and turning a blind eye to the sound in the house. The order they received was that within a week, no one in the room was allowed to enter and leave, and the food was delivered by hanging.

Wei Si forgot how long he had been in this room. He was worried that he would be infected with smallpox and finally died here. At this time, he understood what experiment he had been arrested for, which might be to treat smallpox. Otherwise, he would not have locked them up with a person infected with smallpox. Of course, it might be that it was His Royal Highness the Prince's conspiracy to make them infected after they were infected with smallpox...

One week later.

"How is the situation!"

Yu Zhiqian has been waiting anxiously for the news these days. In the first trial, he even prepared for failure. However, during the first round of trials, only two of the eight people had fever symptoms, and the other six people had some simple abnormalities in their bodies, such as dizziness, etc., but overall, all these eight people survived it.

The second round of experiments is to see if antibodies actually appear in their bodies, which can really prevent smallpox infection.

A week later, Yu Zhiqian stood about two hundred meters away, holding a telescope to observe the isolated small house. Several soldiers were wearing thick sealed clothes and opened the door. No one came out. Yu Zhiqian frowned. Are all eight dead?

"Call and let the people inside come out!"

"Here!"

Someone waved the flag, and soon the sergeant opposite understood and shouted loudly: "Listen, your people, walk out of the room immediately!"

It took about a minute to move in the room. Wei Si Zhan was tremblingly, blocking his eyes with his hands, and slowly walked out of the room, followed by the second, third, fourth, fifth...

In the end, all eight people stood at the door. After Yu Zhiqian saw it, his eyes lit up. It seemed that his vaccine test might have been successful. Cowpox can really prevent smallpox. These eight death row prisoners have never had smallpox before, and there could not be antibodies in their bodies. After spending a week with a person infected with smallpox and not being infected with smallpox, it means that his experiment was really successful.

"I'll inform these eight people to take a shower. After taking a shower, I'll quarantine for a while and check it out. I'll go to the palace to report the situation!"

After Yu Zhigan finished speaking, he quickly left the next area, but leaving the isolation area requires a lot of cumbersome procedures. Even when Yu Zhigan enters this refugee area, he has to change his clothes, rinse his body with simple disinfectant water, and finally change his clothes before leaving to ensure that no virus will spread.

During this period, Chang'an City has also been searching for people infected with smallpox everywhere, but they are lucky. The two yamen runners did not go around like some running idiots. They were sick and had dinner with friends everywhere, so no new cases were found in Chang'an City, but there were five or six infections in that refugee village.

Yu Zhigan rushed back now just like the emperor reported the progress of vaccine research. The smallpox vaccine experiment was successful, and there was no need to say too much to contribute to the Yu Tang Empire. At least this kind of plague has a good way to prevent it.

In the palace.

"Baoshi, this damn Wang Dong, I was really blind at the beginning, and I thought he was a capable minister and a waste. Have you found out that he is there?"

"When you go back to your Majesty, I have sent someone to investigate the whereabouts of Wang Dong and his family, but it has not been found yet!"

"I'll do it thoroughly. After finding it, I'll escort it back to Beijing. I'll ask in person, this..."

Before entering the hall, Yu Zhigan heard the roar of his cheap father. After listening a little, Yu Zhigan roughly understood what was going on. It seemed that something might really happen in that place on Shannan Road, and it might be even more terrifying than he expected!

"Your Majesty, Your Highness the Crown Prince asks for your meeting!"

"Prince!"

Yu Zhigan quickly walked into the hall: "My son has met his father!"

"I'm here just right, look at the report from the Jinyiwei!"

After saying that, a memorial was thrown in front of Yu Zhigan. After Yu Zhigan opened it and quickly glanced at it, the memorial in his hand almost fell directly to the ground and looked at Jing Ke: "These are all true!"

"Your Highness, it's true!"

"Wang Dong, I will kill him!" Yu Zhigan said gritting her teeth.

The smallpox epidemic began to break out in February of this year in Shannan Road. At first, it was just in a city and did not attract too much attention. However, after April, the smallpox completely broke out, and in May, most cities in Shannan Road had smallpox explosions.

But at this moment, Wang Dong, the governor of Shannan Road, kept hiding it without reporting it. It was not until some time ago that Shannan Road revealed that there was a plague on Shannan Road, but the epidemic could no longer be controlled at this time. Even so, in order to prevent any victims from escaping, Wang Dong revealed that he would block the victims from escaping in some pass areas of Shannan Road.

Originally, this matter was intended to control the epidemic, but Wang Dong not only prevented the disaster victims from moving, but even hindered any person who reported the epidemic to Chang'an. The secret message of the Jinyiwei was intercepted in Shannan Road. In addition, there was no news from the intelligence organization in the hands of the emperor.

When the Jinyiwei spies arrived at Shannan Road, Wang Dong seemed to have received the news that Wang Dong and his family all disappeared overnight as if they had evaporated from the world.

This is one of his charges. In addition, after the smallpox outbreak, some activities were organized in Shannandao. Because of this activity, the infected person was unknown. In addition, Wang Dong also colluded with his wife and brother to purchase some items such as food in Shannandao and raise prices.

It can be said that the crimes committed by Wang Dong are beyond words!

"Father, son-in-law think that people should be sent to Shannan Road for disaster relief immediately. After the disaster relief is over, we must thoroughly investigate all the officials in Shannan Road. Such a big thing cannot be that Wang Dong alone covers the sky. There should be many officials having problems, and even all officials in Shannan Road have problems. None of these people will be left behind!"

A murderous intent flashed in Yu Zhigan's eyes. This was the first time Yu Zhigan had such a great murderous intent after he traveled through time. Although he is now the prince and the ruling class, he began to consider the ruling class, but who is the ruling class ruled? It is the people, and there is no more people, and there is still the ruling class?

Moreover, if this matter is not handled well, the Yu family may permanently lose the people's hearts of Shannan Road. Shannan Road will be like a time bomb and may break out at any time. Yu Zhigan is so angry that he wants to be the world's largest playboy. If you don't have this, what will you do? Even if you want to lose, the Yutang Empire should be defeated in your own hands.

"Has the vaccine been developed?"

"The father has already studied it, but the vaccine can only prevent people who have been vaccinated from being infected with smallpox, but it cannot treat smallpox. I asked Hua Tuo and Zhang Zhongjing that they have a way to treat smallpox, but they cannot guarantee a 100% cure. The epidemic in Shannandao is already difficult to control, and the medicinal materials needed are unknown..."

"The Ministry of Revenue will try its best to cooperate with you, but who will go to this disaster relief?"

This is a big problem. This matter is related to the foundation of the empire's rule. The emperor would not send someone at will. Most of the trusted ministers are already old. Or they are like Cheng Yaojin, who can help or not know whether they can help in the past, but it is certain that they cause trouble, so the emperor is very entangled.

Yu Zhigan looked at the emperor, thought for a while, and then slowly spoke: "Father, this matter is of great importance. I think it is safest for me to go to Shannan Road in person!"

After hearing this, the emperor glanced at Yu Zhigan: "No, Cheng Xiang is about to give birth, you have to stay in Chang'an City!"

"Father, the country, the country comes first, and then the family is important. If handled improperly, it may cause civil rebellion in Shannan Road and even the surrounding areas. All the ministers who are capable of handling this matter are already thousands of miles from Chang'an, and they are working on a boat and a car. If they are unfortunately infected with smallpox, they may..."
