For the Great Wei court at this time, it was in response to the old saying: the house leak happened to rain overnight, and the ship was late and encountered a head wind.

The local plague in Jiangnan has not yet subsided, and the Hu people in the south have killed them again, which can be described as two ghosts knocking on the door.

Although it is said that it is two things, anyone with a discerning eye can see that whether it is the spread of the plague or the invasion of Jiangnan, it is actually all a situation laid out by the Hu people.

Although the Hu people are ferocious, they are relatively small in number after all. And there are millions of troops stationed in Jiangnan, and if the two sides of Hu and Wei really want to fight, it is difficult to determine the outcome of the battle.

Compared with the Hu people, the plague is more serious.

Due to the large number of displaced people who have fled from the affected areas, the large-scale spread of the plague has become a completely uncontrollable matter.

Including Xinjing, all the prefectures and counties that had not yet had the plague were all closed, and they did not dare to let any outsiders in.

But even so, there will still be sore-scattering patients in the city for no apparent reason, and it is not known whether it was the work of the Hu people lurking in the city or it was transmitted from other places.

For these patients who suddenly appear with loose sores, if the local government finds it early, they can still be isolated. But unfortunately, most of the time it is too late to find out, and the infected person has already infected many people in the local area.

This plague that once broke out in the northwest is spreading to the entire south of the Yangtze River at an alarming speed, and it is menacing.

In the case of this epidemic completely out of control, some people in the DPRK and China finally remembered the original "vaccination" method created by Su Zhen, the youngest son-in-law of Ning Zhiyuan, the head of the "chaotic party", which can prevent people from dispersing sores.

At that time, due to the strong opposition of the Tai Hospital, this special treatment that required the implantation of sick cow slurry into people was not promoted on a large scale in the capital.

Now in the face of the menacing tide of the plague, the princes and ministers in the court can no longer care whether this method is against human morality, and strongly demand that the court reactivate the law to prevent the continued spread of the plague.

With the acquiescence of the Xie family and others, Emperor He'an immediately ordered the Tai Hospital to restart the vaccination method, and took the lead in implementing it in Xinjing, and there must be no mistakes.

After receiving the holy decree, the doctors of the Tai Hospital hurried to find the two sick cows that Chi Fei had brought to the capital from the northwest as a source of vaccination.

Fortunately, when the capital was moved, a doctor called someone to bring these two sick cows that were of great significance back then.

However, when the doctors went to check on the two sick cows, they were all dumbfounded.

The two sick cows had already healed, and there were no abscesses on their bodies that they had seen before.

They remembered that Su Zhen had said that pus must be extracted from the abscesses of sick cows and planted on human wounds in order to prevent the sores from being dispersed.

But the abscesses on the two cows have all healed, what can I do now?

Seeing this, the doctors of the Tai Hospital suddenly fell into a dilemma.

If you want to find a sick cow that can be used, you may have to go to the northwest to find it. But now that the northwest is firmly controlled by the Ning family, this method will not work at all.

But if there are no sick cattle, how can they be inoculated?

Besides, the holy decree has been issued, and if the holy decree cannot be completed on time, the imperial court will definitely blame it, and no one can afford this responsibility.

At this time, someone suggested that it would be useful to simply extract cow blood from two sick cows and then inoculate them into humans.

When the doctors heard this, they felt that it made sense.

Since pus has an effect, the cow blood should be the same, anyway, it is something extracted from two sick cows, and it stands to reason that the effect should be the same.

In addition, Emperor He and the adults in the court are urging so much, they don't have time to take care of so much anymore, so let's get things done first, so as not to condemn the court.

Without further ado, the imperial physicians hurriedly extracted a large amount of cow blood from the two sick cows, and then inoculated the people of the whole capital in the name of the imperial court.

This practice of using it directly on the human body without testing may seem very ignorant and ridiculous to modern people, but the imperial doctors are afraid that the imperial court will blame them, and secondly, they would think that the virus vaccine also has a shelf life, and they don't understand the biological principles in it, so that they have made such a big oolong.

Because the doctors mainly treat the princes and nobles on weekdays, the hospital has a high reputation and status among the people.

Now that I heard that the doctors of the Tai Hospital were going to give the people of the whole city a divine prescription that could not disperse sores, the people of Xinjing naturally flocked to the Huimin Bureau to get vaccinated with gratitude.

Some people with bad legs and feet simply let their family members carry them over with a wooden plank to get vaccinated.

Whether it is a prince or an official, or a common person, all must be vaccinated.

The difference is only that the people have to go to the Huimin Bureau to get vaccinated on their own, while the princes and officials will have special imperial doctors to go to the palace to vaccinate them, to show the difference in the status of the two.

Because the imperial court attaches great importance to this matter, and everyone is afraid of death, but after ten days of hard work, the people in Xinjing have been successfully vaccinated.

Now that Xinjing has been vaccinated, it stands to reason that it should be the turn of other provincial capitals.

It's just that there are people rampant outside, and if you go out rashly, it may be dangerous.

Some officials have proposed that the law of vaccination can be used to recruit people in chaos.

That is, those who are willing to submit to the court will not only be not guilty of their past transgressions, but will also be inoculated to protect them from the suffering of sores.

As long as the court is willing to open this mouth, most of the rebellious people will stop making trouble because they are grateful to the court, and they will return to their original places and become obedient people.

In this way, the siege of the rebels should be solved quickly.

This plan was immediately approved by the sick An Guogong, so He An immediately issued a holy decree to do so.

This method was indeed effective, and with the deliberate recruitment of the imperial court, many rebellious people gradually settled down and stopped looting everywhere.

Most of these people were originally ordinary people who were in peace and order, but they were driven to a dead end, and they were instigated by people with good intentions, so they had to become chaotic people who looted everywhere.

Now that they have heard that the court has promised to absolve them of their faults and will inoculate them, most of the people are still willing to submit to the court.

After all, no one wants to really rebel, this is a big crime of stealing the family and exterminating the clan, and few people have the courage to do so.

After vaccination, many people began to return to their hometowns one after another, led by the imperial court soldiers.

As soon as this person left, the passage that was originally blocked by them was naturally dredged.

Although there are still some rebel forces still waiting and seeing, so far, the recruitment of rioters in various places has been carried out quite smoothly.

After pacifying these rebellious people and clearing the passages, the imperial court immediately began to implement a vaccination campaign throughout Jiangnan.

Many imperial physicians were appointed by the imperial court as temporary medical officers and sent to various places to preside over vaccinations.

In this way, following Xinjing, all provinces in Jiangnan have also launched large-scale vaccination campaigns one after another.

For the good deeds of the imperial court, most of the people everywhere were grateful to Dai De and shouted the emperor's sage.

However, when a huge vaccination campaign was being carried out in various parts of the Yangtze River, a doctor surnamed Chen faintly felt that something was wrong.

When Chi Fei was demonstrating how to vaccinate cowpox to the doctors in Tai Hospital, this Tai Yi Chen was also one of the Tai doctors who watched the whole process.

Although most of the doctors in the hospital strongly opposed this special treatment of planting things from livestock on people, believing that it was against human ethics, Taiyi Chen was one of the very few people who were very interested in this inoculation method.

Afterwards, he personally visited Chi Fei and asked him some questions about vaccination.

Especially on the question of how to identify whether the vaccination is successful, Chi Fei once clearly said to him that the most important point to identify whether the vaccination is successful is to identify whether the vaccinated person has symptoms similar to scattered sores.

If there is one, it means that the vaccination is successful, otherwise if it does not, it means that it is not successful.

When the Tai Hospital vaccinated the people of Xinjing under the order of the imperial court, Taiyi Chen has been paying attention to whether the vaccinated people have symptoms of sores.

However, he was surprised to find that none of them had symptoms similar to scattered sores, and even no symptoms at all. This made him very uneasy.

It stands to reason that he should report this kind of thing to the Tai Hospital immediately, but he didn't dare to do it.

The reason is very simple, now Su Zhen is one of the rebel parties in the imperial court, and he is also the son-in-law of Ning Zhiyuan, the leader of the rebel party. In the arrest warrant of the imperial court, it belongs to the top few big people.

If Imperial Physician Chen truthfully reported what Chi Fei had told him in private back then, wouldn't it be true that he had a personal relationship with the chaotic party Su Zhen?

Today's imperial court is extremely strict with all those who are related to the chaotic party.

It is very likely that as soon as he reports it here, the people from the Detective Office over there will come to the door to raid the house and arrest people.

He has seen too much what will happen to the officials and their families who are taken away by the Secret Office.

He didn't want to die, let alone his family would fall into that miserable situation, so he didn't dare to report the matter to the hospital.

The only thing he can do now is to stock up on as much food as possible at home, and strictly prohibit his family from going out at will, so as not to get infected.

Imperial Physician Chen now only hoped that the cow blood extracted from the sick cow would really be useful, otherwise he would not dare to imagine what terrible scene would happen next.

However, as the so-called good spirit does not lead to bad spirit, half a month later, Imperial Doctor Chen's worries finally came true.

In various areas that had been vaccinated, there was a sudden resurgence of the plague.

Especially those people who have just escaped from the epidemic area, and after receiving the vaccination organized by the Tai Hospital, they have returned to their hometowns under the guidance of the government.

Thinking that they would not get rid of the sores after being vaccinated, these people returned to the county town or village that was originally the epidemic area.

As a result, not long after these people returned, many of them began to show symptoms of scattered sores one after another, and the number of infected people suddenly rose to tens of thousands.

Not only in these remote areas, but also in many military camps and civilian areas in Xinjing, there are more and more patients with scattered sores, and these infected people are all people who have already been vaccinated.

Due to the large number of infected people and their widespread dispersion, they are spreading at a rate far from being comparable to before.

In this way, this great plague, which was later called the "He'an Plague" by historians, finally showed its fangs to everyone.
