Xia Yunyi was a little surprised, he didn't expect Zhang Gui to behave so firmly on smallpox.

Seeing this, Zhang Gui also guessed the doubts in his heart, so he said:

"I forgot to tell you that during the time you weren't in the capital, the doctors of the Medical Hall Epidemic Prevention Research and Development Institute founded by our West Factory in Xishan successfully cultivated vaccinia with very low toxicity."

"And many people in Benhou and Xishan have already been vaccinated with this pox, so that there were a few homeless people in Xishan who suddenly contracted smallpox, but they also planted pox in advance and did not cause a large-scale smallpox epidemic!"

"We also use a new ice-making method to extend the shelf life of this slurry."

"Right now, Ben Hou has asked people to bring some here, so that they can quickly vaccinate the people of Suizhou with the method of cowpox vaccination, so as not to cause smallpox plague in the area where we are piloting the law."

"Vaccinia vaccination?"

Xia Yunyi was quite suspicious after hearing this.

Zhang Guidao: "How could Ben Hou lie to you, this method is indeed effective!" ”

"Ge Hong of the Jin Dynasty said in "Elbow Reserve Emergency Prescription" that the use of less virulent of the same type of epidemic virus agent injected into the human body can achieve the purpose of epidemic prevention."

Ben Hou also got inspiration from this, and asked them to try to choose the slurry of human pox, cowpox and other pox diseases, which is less toxic and has the best epidemic prevention effect, to eliminate smallpox. As a result, a way to eradicate smallpox was found. ”

Xia Yunyi saw that Zhang Gui could still tell the reason, and Ge Hong was indeed quite famous in history, so he was more convinced, and said: "I didn't expect that there was a method to prevent smallpox in the Jin Dynasty. ”

"Therefore, Benhou Pingsu asked you to read more books of the hundred schools of thought, not only to know the scriptures and the Tao."

"My Chinese cultural accumulation has always been profound, there are many knowledge that needs to be explored and inherited, don't stick to the learning of a family, and don't know how to seek truth from facts to explore the knowledge that is conducive to the livelihood of the society!"

Zhang Gui said and said: "For example, the technique of smallpox prevention and control, in addition to the technique of planting pox has already been mentioned by the ancestors of my Han family, and the mechanism of smallpox transmission has already been written and recorded by someone according to their own practice, do you know?" ”

Xia Yunyi waved his hand and said, "Please advise Master Hou!" ”

Zhang Guidao: "During the modern temple period, the great Sima Guo Zizhang had a monograph called "Boji Rare Pox Formula". ”

"It records that smallpox is transmitted by the spread of qi, and this qi meets people's true qi, which is incompatible with each other, which can make people infected, and the amount of true qi given by people is different, so there are different degrees of disease!"

"And his practical experience is that those who have been cured of smallpox should be decisively isolated, and those who have been cured of smallpox should be the soldiers of epidemic prevention, and they will be responsible for supervising the sick, because these people who have been cured of smallpox will often not be infected again, and they are all people who are full of true qi."

Zhang Gui was a human being in his two lives, and he was a practitioner in medical experiments in his previous life, so he is still very clear about the development history of immunology, and he knows that the ancient Chinese did find many rules in the practice of epidemic prevention against smallpox.

For example, as early as the Jin Dynasty, there was a theory that a low-virulence strain was injected into the human body to produce an immune response, and during the Ming Dynasty, there was a view that the virus was transmitted through the air.

As for why the natural sciences are inferior to the West, this is not something that can be explained clearly in one or two sentences.

In short, Zhang Gui has to admit that because these immunology and disease epidemic prevention theories that have been summarized by predecessors have not been well inherited and developed, and are rarely even known by scholars, many times, future generations do not know the research results of their predecessors, so that they do not know how to use them in life practice.

Xia Yunyi also learned about these books for the first time through Zhang Gui, and as a child who only received Confucian education, he did not have the awareness that many non-Confucian knowledge in China needed to be inherited and carried forward.

Zhang Gui here directly instructed Zhou Neng, who came with him: "You go and pass on my words, let Wu Youke, Imperial Doctor Wu and Xiao'e, who came with Ben Hou, go to Qinjiazhuang first, and plant pox on the people who have not yet become ill, including a few Zhuangzi around, quickly!" Imperial Physician Wu is responsible for inoculating pox for the military and civilians, and Xiao'e is responsible for inoculating pox for women, children and children, sending a team of official schools to follow them, and temporarily listen to their moderation, and be responsible for rectifying the epidemic prevention order! ”

"Yes!"

Zhou Neng agreed.

After Xiao'e stayed in Xichang, Zhang Gui found that she had a good memory and a good tolerance for flesh and blood, so he asked her to go to the women's medical hall opened by Xichang for orphans to learn medical knowledge such as gynecology and disease prevention, and now Xiao'e has mastered the art of pox.

Zhang Gui's original intention was to let her inoculate the women and children here.

After Zhang Gui arranged the pox, he arranged for Xia Yunyi, the governor of the state, to personally establish an isolation point and set up a special shelter for smallpox infected patients, while Wu Youke and Xiao'e still treated male and female infected patients respectively.

Although the mortality rate after smallpox infection is high, Zhang Gui still hopes that by treating these infected people, he can help several infected people to finally overcome smallpox by relying on their own immunity and thus recover.

Because of the timely planting of pox and the timely prevention of the epidemic, smallpox was finally controlled, and there was no large-scale outbreak in Suizhou, and even smallpox in Qinjiazhuang was also controlled, and in the end there were 16 infected people.

Xia Yunyi breathed a sigh of relief, and only then was he very convinced that this was not the heavenly punishment that God had imposed on him after changing the law in Suizhou.

"The son is silent, the strange force is confused! You can't worry that the heavens are not happy with you because you are afraid of the plague. ”

"The Exotic Reclamation of Vegetable Skeletons"

"The way of heaven is to make up for the deficiency when there is more loss, and when we change the law, we will make up for the deficiency when we lose more than we lose, where will it violate the way of heaven! Even if Heaven is not benevolent, then it does not mean that it is wrong to feel that it is wrong to change the law for the country and the people! ”

Zhang Gui also educated Xia Yunyi after this incident.

Xia Yunyi humbly taught: "What Master Hou taught is that later life is also concerned about chaos. In addition, the late life did not expect that the ancients had already learned about smallpox, but the late life was ashamed, if it wasn't for the Hou Ye mentioned it today, the late life would not know these knowledge! It can be seen that the shallowness of late life! ”

"It's good that you have this humility!"

"But Ben Hou still said that, you and I must consciously carry forward all aspects of my Chinese knowledge, and benefit the people's livelihood, and we can't make some beneficial knowledge faults buried in the pile of paper!"

"Even if you don't have the energy to carry it forward, you have to fund others to do these things, and put a few more technical subordinate officials around you who specialize in medical science, arithmetic, science, water control, agriculture and other specialized categories, and support them to summarize and carry forward all kinds of knowledge from ancient times to the present, and provide reference for your governance at any time, so as not to be at a loss when something happens, or not be able to take precautions!"

Zhang Gui took the opportunity to continue to teach Xia Yunyi.

Xia Yunyi humbly bowed his hand and said, "Remember the teachings of Master Hou in your later life!" The late students asked the imperial court to let the late students add these subordinate officials, and invest money in them to summarize and carry forward the learning of ancient and modern families, and benefit the society and the people's livelihood! ”

Zhang Gui nodded happily: "In this way, maybe my Daming will achieve a prosperous era that surpasses the previous dynasties!" ”

"What Master Hou said is true!"

Xia Yunyi replied, and said: "However, Master Hou, this time the smallpox is really strange, and I am worried that this is deliberately done by someone, and the purpose is to change the law and the new policy piloted in Suizhou!" ”

"It's just that even if it's artificial, it's not easy to check, after all, there are so many people coming in and out of Suizhou, and it's difficult to check them all."

Zhang Gui thought for a while and said, "Then let people deliberately release fake news!" It is said that Suizhou smallpox is overflowing, and when the time comes, someone in the court will stand up and make trouble, and at that time, you can know if anyone is doing ghosts, and you can also know who is doing ghosts! ”

After hearing this, Xia Yunyi asked, "What does Master Hou mean to plan the plan?" ”

Zhang Gui nodded.
