Since Chi Fei needed to prepare and it took time to find a suitable death row inmate, the comparative experiment was scheduled to be held in three days.

Facing this final test, Chi Fei was also quite nervous in his heart, but after doing so many experiments, he was still relatively sure in his heart.

Soon, three days passed, and Ning Zhiyuan once again came to the camp with two messengers and ten death row prisoners.

Before the experiment began, Chi Fei first pointed to a small bowl on the table and explained to the two Qincha, "Two adults, this bowl contains the pus that was just extracted from the sores patient in Pingnan County yesterday. ”

When Zhao Tianzheng, a scholar of the Hanlin Academy, and Xu Jiahua, a soldier in the military department, heard this, they instinctively shrank back.

Of course, they will also feel afraid of the fierce plague that makes people smell and change their color, but they will not be able to avoid it.

Xu Jiahua couldn't help but ask, "Brother Su, wouldn't it be good to dry the pus directly like this?" ”

Chi Fei reassured, "Don't worry, the two adults, as long as they don't get on their bodies, they won't be overcome." ”

The two of them were a little more relieved.

Ning Zhiyuan glanced at them with a smile behind him, and then said, "Ah Zhen, I brought the death row prisoner you wanted, can you start?" ”

"Let's get started, father-in-law." After speaking, Chi Fei ordered the soldiers to bring up the ten death row prisoners who had been vaccinated.

As for the ten unvaccinated death row inmates brought by Ning Zhiyuan, they ranged in age from thirty to fifty years old, looking a little nervous and frightened, but their appearance was quite clean and tidy, and they had obviously taken a shower and changed their clothes before coming.

And in order to distinguish them from the camp death row inmates, they are all wearing white short coats, which is clear at a glance.

After everyone arrived, Chi Fei used a knife to make a small cut on the arm of the death row prisoner one by one in front of everyone, just like he had planted pox before, and then dripped the pus of the sore-dispersing patient on the wound and waited for it to be completely absorbed.

After all the twenty death row prisoners were vaccinated, Chi Fei said to the two Qincha, "Lord Zhao, Lord Xu, I will divide these people into the same camp so that the two adults can supervise them."

Although they were wearing different clothes, please remember their faces so as not to be confused. ”

Regarding Chi Fei's fearless attitude, Zhao Tianzheng and Xu Jiahua couldn't help but start to be suspicious, feeling that this person really didn't look like a fraudster.

To be on the safe side, they wrote down the appearance of each prisoner.

Next, it will take at least a few days for these death row inmates to break down. In other words, the two chincha need to stay in the camp until the results are verified.

Just after the soldiers took the twenty death row prisoners to a separate barracks, Ning Zhiyuan suddenly said in a big voice, "Ah Zhen, it's a rare opportunity, you come and help me get vaccinated, otherwise I don't know how long it will be delayed next time." ”

As soon as these words came out, Zhao Tianzheng and Xu Jiahua suddenly looked at him with shocked faces.

Zhao Tianzheng immediately objected, "General, you are now in danger of the entire northwest, how can you easily get into danger?"

Don't do this until you get a definite result. ”

Xu Jiahua also persuaded, "Yes, Ning Gong, you take it slow first, and wait for the results to come." ”

Ning Zhiyuan smiled and said, "What are you worried about, my son-in-law and my youngest son have been vaccinated, and there is nothing wrong with it."

Don't look at me, I don't seem to be afraid of anything, in fact, I'm so scared that I scatter sores.

Okay, okay, that's it, don't be verbose. Ah Zhen, when can it start? ”

Chi Fei couldn't help but smile and said, "Wait a minute, you can start, father-in-law, you can go to the camp first and wait for your son-in-law." ”

"Okay, then I'll go first." Ning Zhiyuan raised his feet and left.

"General, listen to me, this matter is not trivial, you really can't get into danger!"

"Ning Gong, wait a minute, you can listen to us first, Ning Gong ......"

Zhao Tianzheng and Xu Jiahua hurriedly chased all the way over and persuaded them non-stop.

Ning Zhiyuan didn't bother to pay attention to them, and continued to stride towards the tent.

Looking at the two people who followed closely behind his father-in-law, Chi Fei couldn't help but feel a little moved in his heart while feeling funny.

He knew that his father-in-law took the initiative to get vaccinated at this juncture, which was actually helping him build momentum.

Saying a thousand things and ten thousand, how can it be more convincing than the Northwest General Ning Zhiyuan personally going into battle?

But that's good, his father-in-law is the backbone of the entire Ning clan, and the sooner he inoculates cowpox, he will be able to immunize smallpox one day earlier, which is a good thing for all of them.

Under the strong opposition of Zhao Tianzheng and Xu Jiahua, Ning Zhiyuan still stubbornly vaccinated with cowpox.

As a result, that night, he developed a low-grade fever and a noticeable red rash on the wound.

This suddenly made Zhao Tianzheng and Xu Jiahua's hearts rise.

It is not a lie for them to say that the general is in danger of the entire northwest, and after so many years of covering the entire Great Wei, only the Ning family is really capable of fighting against the Hu people in the north, and the others cannot afford this heavy responsibility at all.

Ning Zhiyuan is a general in the northwest appointed by the saint, and he is also the patriarch of the Ning clan, so his importance does not need to be expressed at all. If something happens to him, this will definitely be a big event for the entire Great Wei that will shake the government and the opposition.

Because of this, both of them knew very well that if something really happened to the Great General, those of them who happened to stay by his side but could not stop him would definitely not be able to escape the wrath and punishment of the Holy One.

Compared with the extreme nervousness of the two Qincha, Chi Fei was very calm and had already seen it.

In addition to taking care of his father-in-law himself, he did not even invite a doctor to come and treat him.

The two of them were bored and played Go, of course, Chi Fei, a Go novice, was not a father-in-law's opponent who knew how to do this, and he was killed and had no power to fight back.

Because Zhao Tianzheng and Xu Jiahua were also afraid that they would be infected and scatter sores, they did not dare to approach Ning Zhiyuan, but they came over from time to time to inquire about his situation, so they left plenty of room for Weng and his son-in-law to communicate.

"Ah Zhen, as long as the vaccination method can be implemented smoothly, I want to report your name to the imperial court and bring you back with a good lead." When Ning Zhiyuan was playing chess, he suddenly said.

"Father-in-law, my son-in-law is just a commoner, and this credit is useless to me. Why not just give it to the eldest or second brother? ”

"Silly boy, it's because your eldest brother and second brother are my sons that you can't let them take this credit.

Our Ning family's reputation is too great, and if we get such a great achievement, I am afraid that it will cause people to be jealous. ”

Chi Fei pointed to the sky with an inquiring look.

Ning Zhiyuan nodded lightly.

Chi Fei didn't know, it turned out that his father-in-law was afraid of high merit.

Sure enough, accompanying the king is like accompanying the tiger, this sentence is not wrong at all.

Compared with the two brothers Ning Yabai and Ning Yafeng, Chi Fei is just a son-in-law after all, strictly speaking, he is a foreigner. So even if he earned this great achievement, the impact on the Ning family would be relatively small.

Chi Fei thought about it for a while, and said calmly, "Then trouble my father-in-law to help my son-in-law report to the court, so that my son-in-law can get back into the limelight." ”

"Haha, my son-in-law is so capable, he shouldn't be a person who doesn't know nothing. Rest assured, this time it will make you shine. Ning Zhiyuan laughed loudly.

What he likes most about his little son-in-law is that once he decides what he wants to do, he will be very simple and decisive, and he will not drag his feet at all. That's very much to his appetite.
