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

Wei Si is a death row prisoner, his wife committed adultery with others, came to the door to kill other people's whole family, and later went to the yamen to surrender and surrender, and was sentenced to be executed after the autumn.

He has not been out of death row since he pleaded guilty, and he knows that there are only two ways for death row inmates to leave death row, either to die on death row or to be sent out of death row and executed.

"It's still summer, what are you going to take me out for?"

Wei Si asked a little nervously, after killing people, he was already determined to die, but during the time he was waiting to die on death row, he didn't want to die more and more.

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

Soon the carriage stopped, and he saw that he was taken to a mansion, and Wei Si didn't know a word of the words on it, he didn't know the words, and many people were illiterate.

The mansion was very luxurious, this was the most luxurious mansion Wei Si had ever seen, larger than the mansion outside the Huang Yuan in their workshop.

"Get in!"

The sergeant pushed Wei Si into the mansion, and after a few minutes or so, other carriages came one after another, and eight people were gathered in an open space with him.

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

But soon Wei Si believed it, because this young man told him that he was the crown prince of the dynasty, and the prince he had heard of it, and he was a very powerful person, as for how old the prince was, he didn't know, the emperor's son, if he didn't kill himself, he shouldn't kill himself, right? Wei Si was overjoyed in his heart.

But the joy lasted only a few minutes before it vanished, for he saw a man pull a cow and then bust it on it, and then cut the arm of the same death row prisoner not far from him, and poured something on it.

Fear, Wei Si was scared, he didn't know what this was for? But it doesn't feel like a good thing, he wants to go back to the cell now, he feels that the cell is safer than here, he knows that there is no bread in the world, he is guilty of beheading, and being able to pardon his own crime must be more dangerous than killing his head.

But the struggle was useless, the two sturdy sergeants, their hands were like pliers, grabbed Wei Si's arm, Wei Si couldn't move at all, and then the Lang Zhong came to Wei Si, like the previous people, cut a cut in his arm, and then dripped something unknown into his wound.

It didn't hurt very much, Wei Si breathed a long sigh of relief in his heart, and after the rest of the people were all planted with these things, Wei Si was taken away again and taken to a small room, where he lived alone, surrounded by darkness, only some light that came in through the cracks, making him feel that he was still alive.

On the first day, I didn't feel anything, someone brought food on time, these meals were much better than death row, even better than what he used to eat at home, there was meat, vegetables, and the amount was more, if he didn't know that he was a death row prisoner, Wei Si even had the urge to live here all the time, at least, there was no worry about food and clothing here, and the food was good.

But by the next day, Wei Si felt that he was chilled and feverish, his body was constantly swinging, cold and hot, Wei Si felt that he might die, and he might die very painfully.

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

"This man has smallpox!"

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

"Smallpox!"

The other seven people looked at the person lying on the hospital bed, and were so frightened that they took two steps back, and the more sturdy prisoner took a deep breath and hammered them hard: "This person has smallpox, we want to go out, we want to go out!" ”

The noise was loud, but no one responded, and the closest person to them was also more than ten meters away, wearing heavy protective clothing, and turned a blind eye to the sounds in the house, and they received an order that no one in that room should enter or leave for a week, and that food delivery would be hanged.

Wei Si forgot how long he had been in this room, he was worried that he would be infected with smallpox and eventually die here, at this time, he somewhat understood that he was arrested to do experiments, maybe to treat smallpox, otherwise, they would not be locked up with a person infected with smallpox, of course, it may also be that His Royal Highness the Crown Prince has some conspiracy to let them be infected with smallpox and spread it......

A week later.

"How's it going?"

Yu Zhiqian has been anxiously waiting for news for the past few days, and he was even ready to fail in the first test, but in the first round of tests, only two of the eight people showed symptoms of fever, and the remaining six people only had some simple abnormalities in their bodies, such as dizziness and so on, but in general, these eight people carried it.

The second round of experiments was to see if they really had antibodies in their bodies that could really prevent smallpox.

A week later, Yu Zhiqian stood about two hundred meters away, holding a telescope to observe the isolated room, several sergeants wearing thick sealed clothing, opened the door, no one came out, Yu Zhiqian frowned, could it be that all eight people died?

"Shout, let the people inside come out!"

"Whoa!"

Someone waved a flag, and soon the sergeant on the opposite side understood, and shouted: "Listen, get out of the room immediately!" ”

It took about a minute for there to be movement in the room, Wei Sizhan trembled, covered his eyes with his hands, and slowly walked out of the room, then the second, the third, the fourth, and the fifth......

In the end, eight people stood at the door, Yu Zhiqian's eyes lit up after seeing it, it seems that his vaccine test may have really succeeded, cowpox can really prevent smallpox, these eight death row prisoners have never had smallpox, there can be no antibodies in the body, and a person infected with smallpox stayed together for a week, and was not infected with smallpox, indicating that his experiment was really successful.

"Inform it, let these eight people go to take a bath, after taking a bath, isolate for a period of time to check, and I will go to the palace to report the situation!"

After Yu Zhiqian finished speaking, he quickly left the next area, but leaving the quarantine area requires a lot of cumbersome procedures, even when Yu Zhiqian entered this refugee area, he had to change his clothes, rinse his body with simple disinfectant water, and finally change his clothes before leaving, to ensure that no one would spread any virus.

Chang'an City was also looking for people infected with smallpox during this time, but fortunately, the two officials did not get sick and have dinner with friends everywhere like some fools running around, so no new cases were found in Chang'an City, but there were five or six cases of infection in that refugee village.

Yu Zhiqian is rushing back now like the emperor to inform the progress of vaccine research, the smallpox vaccine experiment was successful, and there is no need to say too much about the contribution of the Yu Tang Empire, at least there is a good way to prevent this kind of plague.

In the palace.

"Waste, this damn Wang Dong, I was really blind at the beginning, and I thought he was a capable minister, he was a waste, and now I found out where he was?"

"Back to Your Majesty, the minister has sent someone to track down the whereabouts of Wang Dong and his family, but it has not been found yet!"

"Poor, investigate thoroughly, after finding it, escort back to Beijing, I want to ask in person, this ......"

Before entering the main hall, Yu Zhiqian heard the roar of his cheap father, and after listening to it a little, Yu Zhiqian roughly understood what was going on, it seems that there may really be an accident in that place in Shannan Road, and it may be even more terrifying than he expected!

"Your Majesty, His Royal Highness the Crown Prince asks to see you!"

"Xuan!"

Yu Zhiqian quickly walked to the main hall: "Erchen has seen his father!" ”

"It's just in time, look at Jinyiwei's recital!"

After finishing speaking, a piece of music was thrown in front of Yu Zhiqian, Yu Zhiqian opened it and quickly glanced at it, and the music in his hand almost fell directly to the ground, looking at Jing Ke: "These are all true!" ”

"Your Highness, it's true!"

"Wang Dong, I will kill him!" Yu Zhiqian gritted his teeth and said.

The smallpox outbreak began in February this year, and at first it was only in a city and did not attract too much attention, but after April, smallpox broke out completely, and in May, most cities in Shannan Province had smallpox outbreaks.

But at this time, Wang Dong, the assassin of Shannan Province, has been hiding and not reporting, until some time ago, Shannan Province revealed that there was a plague in Shannan Province, but at this time the epidemic was no longer under control, even so, Wang Dong in order to prevent the people from escaping, the news revealed that in some pass areas of Shannan Province, the people were prevented from fleeing.

Originally, this matter was intended to control the epidemic, but Wang Dong not only did not allow the flow of disaster victims, but even hindered any personnel who reported the epidemic to Chang'an, Jinyiwei's secret performance was intercepted in Shannan Province, and there was no news from the intelligence organization in the emperor's hands.

And when the Jinyi Wei spy arrived in Shannan Road, this Wang Dong seemed to have received the news, and overnight, Wang Dong and his family all disappeared as if they had evaporated from the world.

This is also one of his crimes, in addition, after the smallpox outbreak, he also organized some activities in Shannan Province, because of this activity, the infected people do not know how much, in addition, Wang Dong also teamed up with his wife and brother to buy some items such as grain in Shannan Province to raise prices.

It can be said that the crimes committed by Wang Dong are too numerous to mention!

"Father, the son thinks that now should he immediately send someone to Shannan Province for disaster relief, after the disaster relief is over, all the officials in Shannan Province must be thoroughly investigated, such a big thing, it is impossible for Wang Dong to cover the sky alone, there should be many officials who have problems, and even all officials in Shannan Province have problems, these people, not a single one!"

Yu Zhiqian's eyes flashed with killing intent, this is the first time that Yu Zhiqian has such a big killing intent since he crossed over, although he is now the prince and the ruling class, and he is considering things and starting to consider the ruling class, but who is ruled by the ruling class? It's the people, the people are gone, and the ruling class?

And if this matter is not handled well, the Yu family may permanently lose the hearts of the people of Shannan Province, and Shannan Province will be like a time bomb, which may explode at any time, Yu Zhiqian will be so angry, he still wants to be the world's largest gentleman, what if you do this if the Yu Tang Empire does not have it, what should you do? Even if it is to be defeated, the Yutang Empire should be defeated in its own hands.

"The vaccine has been developed?"

"My father has already researched it, but the vaccine can only prevent the vaccinated person from being infected with smallpox, but it cannot treat smallpox, I asked Hua Tuo, Zhang Zhongjing, they have a way to treat smallpox, but they can't guarantee a 100% cure, the epidemic in Shannan Province has been difficult to control, and the medicinal materials needed are unknown ......."

"The household department will try to cooperate with you, but who will go for disaster relief this time?"

This is a big problem, this matter is related to the foundation of the empire's rule, the emperor will not send a person over at will, most of the trusted ministers are already old, or just like Cheng Yanjin's kind of martial arts, I don't know if I can help in the past, but it is certain that the chaos will be added, so the emperor is very entangled.

Yu Zhiqian looked at the emperor, thought for a while, and then slowly said: "Father, this matter is very important, and Erchen feels that it is safest for Erchen to go to Shannan Road in person!" ”

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

"Father, the country, the country, first have the country and then have a family, this matter is very important, if not handled properly, it may cause a civil uprising in Shannan Province and even the surrounding areas, the Manchu Dynasty, the ministers who have the ability to deal with this matter are already old, Shannan Road is thousands of miles away from Chang'an, and they work in boats and cars along the way, if they are unfortunately infected with smallpox, they may ......"

"The epidemic is urgent, Concubine Cheng gave birth to a child, and the sons should have been accompanied, but for the sake of the people of the world, the sons and daughters ......"
