Lu Xiaoyun waved his hand: "Uncle Yang, you misunderstood. What I mean is not that the soldiers are seriously ill. To put it bluntly, the reason why people get smallpox is because they have no immunity. As long as we make the soldiers immunity to smallpox, they will not be infected by smallpox in the future."

Then, Lu Xiaoyun explained the vaccination issue to Yang Hong in the most easy-to-understand words.

Yang Hong seemed to understand but not. Although he believed Lu Xiaoyun, others in the army might not believe it.

Once they have suspicion and are incited by others, they may be in chaos in the army.

After all, what other people were installed in the army by King Chu, Qi Yunxuan and Song Rongsheng, and they did not completely clean up.

"Yunyun, why don't I let the military doctors come and listen?" Yang Hong thought for a moment and said to Lu Xiaoyun in a negotiated tone, "Say something that makes you laugh, Fengyang Pass has not completely cleaned up those people, so..."

"Uncle Yang Er, I understand. Go and call someone." Lu Xiaoyun smiled softly.

"You are always so careful and considerate and take care of other people's ideas. You are such a good girl." Yang Hong said sincerely, "I hope Xiaojiu can be a bit like you in the future."

It would be great if his daughter was so well-behaved. Yang Hong was full of hope. If she grew up in a deserted village and had been influenced by her since childhood, she would definitely be a caring little cotton jacket like Yunyun.

Yang Hong suppressed those thoughts and sent someone to invite a general and a doctor.

The military doctors all came from the medical account and checked the soldiers' conditions. It was clear that they had already shown signs of fever reduction.

Their helpless ceiling seemed to be simpler than the wind and cold in Lu Xiaoyun's hands. They respected Lu Xiaoyun a little more. They should not behave like a person!

"General, Miss Lu, what are the instructions for us to come here?"

"Let Yunyun tell you, I don't understand medicine, Yunyun told me, I'm in vain."

The military doctors looked at Lu Xiaoyun with hope.

Lu Xiaoyun cleared his throat and repeated the principle of vaccination again.

"Miss Lu, does it mean to cause smallpox to be infected with, and to control the severity of the symptoms and to let oneself take it over?" The military doctors responded quickly.

Lu Xiaoyun nodded: "Well, people who have to live with smallpox and are not dying will basically not be infected with smallpox again. So I thought, if people give birth to smallpox once, wouldn't they have to worry about raging again in the future?"

"But how do we control the condition of the sick person?"

"I have my own way of doing this, but you need your cooperation."

"Miss Lu, but it's okay. We will definitely cooperate with Miss Lu. But can Miss Lu say carefully, how to do the vaccine when you get vaccinated?"

"I have to prepare. I thought that the entire army would have to screen for it once to see if there were other smallpox patients, and then the vaccine would be vaccinated."

"But there are nearly 200,000 troops in Fengyang Pass, so it's not easy to get it."

"It's okay, I have time." Lu Xiaoyun smiled, "Everyone is waiting for my news."

"If Miss Lu says this, I'll feel relieved. Let's wait for Miss Lu's instructions."

After the military doctor left, Yang Hong asked Lu Xiaoyun again, "When will the vaccination start?"

The vaccines in Lu Xiaoyun’s space are definitely not enough for Fengyang Pass soldiers.

The current technological conditions are not enough to make better vaccines. It is best to grow cowpox, followed by drought seedling method and water seedling method.

The drought seedling method is to grind the peeling scabs of smallpox patients in the healing period into powder, and blow it into the nostrils of the inoculated person with a tube. The water seedling method is to adjust the powdered scabs with water, then wrap it with cotton balls and stuff it into the nasal cavity. Both methods are artificially infected with smallpox, and the probability of severe illness is high.

Growing vowel is relatively safe.

However, it is a bit troublesome to extract the vaccinia virus. Lu Xiaoyun wanted to solve the smallpox in Fengyangguan earlier, so he decided to use the drought seedling method. After all, there are so many people, and it is also a big burden to use cotton. The court is on guard against Fengyangguan, so the materials can be stuck if they can be stuck!

Lu Xiaoyun told Yang Hong about his thoughts.

Yang Hong was stunned for a moment, but when he thought that Lu Xiaoyun was in charge, there was nothing to worry about.

There are many soldiers in Fengyang Pass, so they isolated those who may be infected and then came to vaccinate them in batches without delaying anything.

"After vaccination, smallpox symptoms may occur, but with the body of Fengyang Pass soldiers, there should be no problem. But I still want to tell Uncle Yang that it is not completely controllable, and it may also be that it will lose my life because of it."

"I'm not cold-blooded. I would rather die some people than let the 200,000 army take risks. As a general, I first defend my country, and then I am myself. Since I am stationed in Fengyang Pass, I must be responsible to Fengyang Pass and the people in the northwest. You don't have to say these words to others."

Lu Xiaoyun looked at Yang Hong, and Yang Hong looked firm and said nothing.

In short, she stayed in Fengyang Pass for a while to see what symptoms would appear, and then she would tell the military doctor how to deal with it. The military doctor had rich experience and should be able to deal with it.

In the next few days, Lu Xiaoyun got busy.

However, Lu Xiaoyun did not leave cowpox, so he asked someone to find a few cows to infect smallpox, and then tried to extract cowpox.

The military doctors were stunned when they knew Lu Xiaoyun’s method of vaccination.

Some people have tried to wear smallpox patients' clothes before, but in the end, many of these people died, and no one dared to touch smallpox patients' things after that.

The first batch of vaccinia seedlings came out soon.

The soldiers were all resistant, and Yang Hong ignored everyone's opposition and was vaccinated as soon as possible.

Seeing this, Ye Mao and the others felt that there was no reason to lose it, and they all received vaccination with the military doctors.

During this period, they all had symptoms, but unlike previous soldiers, they were milder, and after a few days, the disease was cured.

A military doctor was more bold. After he recovered, he took the initiative to contact patients with smallpox, and even took the initiative to collect sores from patients with smallpox and stuff them into his nostrils. What's amazing is that the military doctor was not infected with smallpox again.

This result greatly deepened the soldiers' confidence in the vaccinia.

Many people have resisted from the beginning and started looking forward to early vaccination.

After all, the soldiers in the army who have not been vaccinated have also begun to appear smallpox one after another.

Fortunately, Lu Xiaoyun was in charge, and Lu Xiaoyun did not hide his private training and military doctors, so there was no trouble in Fengyang Pass.

Outside the border, the commander of the Western Regions people was waiting for the so-called opportunity, but he was looking forward to it, and what he was looking forward to was that the Fengyang Pass soldiers who were on duty on the city wall every day were not sick at all, but were surprised to have a surprising spirit.

"The damn Wei people are indeed insidious and cunning. The Fengyang Pass army was not infected with any smallpox. Fortunately, they did not act rashly, otherwise we would fall into the trap." After waiting for more than half a month, the commander of the Western Regions finally realized the reality. There was nothing wrong with Fengyang Pass!

At the same time, he gritted his teeth by the person who sent the message, "If I have the chance to invade the Great Wei in the future, I will definitely kill that person as soon as possible!"
