Although smallpox is controlled in Qingtian County, Qingtian County is too close to Chang'an. The martial law in Chang'an City has not been lifted until now. Chang'an City is the political, economic and cultural center of the Tang Dynasty. As a result, this has had many impacts on the Tang Dynasty, such as soaring grain prices, stagnation of business, and the promotion of high-yield crops by the Ministry of Agriculture...

When Li Xiu found Yang Nong, the old man was still sitting at the checkpoint on the border of Qingtian County and refused to leave. However, when he saw Li Xiu, he immediately jumped up happily, and then the first sentence was to ask Li Xiu to grow cowpox for their officials of the Ministry of Agriculture. Li Xiu did not agree or refuse, but instead took Yang Nong back to the Ministry of Agriculture for details.

"Mr. Prince Concubine, you are from our Ministry of Agriculture. This time the smallpox broke out like this, and I don't know what the situation is in the corn and sweet potatoes in Qingtian County, so you have to help our yamen. No matter what, you have to plant cowpox for the people in the yamen!" As soon as I returned to the Ministry of Agriculture, Yang Nong spoke impatiently.

"Mr. Yang, I know you are very anxious, but in this situation, you can't help it. The cowpox is squeezed little by little from the cows, and the yield is really limited. Qingtian County is also a major agricultural county, and the population in the county is large. It is a big burden for these people to grow cowpox alone. In addition, there are the troops besieging Qingtian County. With the current yield of cowpox powder, there is really no way to grow cowpox for other people!" Li Xiu said with a bitter smile at the end.

The method of growing vowel is indeed very simple. Even if a person who does not understand medicine can complete it with a knife, but the key is the yield of vowel powder. As the saying goes, "A clever woman can't cook without rice." So if there is not enough vowel powder, even if Li Shimin gives orders, there is no way.

"Mr. I don't have many people in our yamen, and we just want to go to Qingtian County to see the growth of those crops. If there is any problem, there is still time to correct it now, but if it takes a long time, it may be too late!" Yang Nong also said bitterly at this time. He also knew Li Xiu's difficulties, but high-yield crops are equally important. Not to mention anything else, the people who starved to death due to famine in the Tang Dynasty every year were no less than those who died of smallpox.

"Mr. Yang, there are not many people in the yamen. There are hundreds of people in total. I can't draw so much cowpox powder for a while. However, I have hidden a little here, which is enough to grow cowpox for one person. It's just enough for you, Mr. Yang!" Li Xiu said to Yang Nong with a smile, and said, taking the porcelain bottle of cowpox powder from his arms.

Originally, there were enough three people in the bottle, but Li Xiu saw that the Yi Niang was a little worried about Pei Ju, so he went to Pei Mansion before, but he didn't expect that Pei Ju was thick-skinned. Not only did he grow cowpox himself, but he also asked Li Xiu to plant his eldest grandson with a dead face. As a result, there was only one person left.

"Can you only plant one person first?" Yang Nong was stunned when he heard Li Xiu's words, and then said in a little confused.

"It's only enough to give one race!" Li Xiu nodded and replied.

"Then it, my son-in-law, you plant Yang Dui first. He is still young and has strong abilities. After he planted cowpox, he can enter Qingtian County to check the growth of corn and sweet potatoes. If he encounters any problems, he will have the energy to solve them!" Yang Nong hesitated for a moment and quickly made a decision.

"Uh? Mr. Yang..." Li Xiu didn't expect that Yang Nong would give this opportunity to Yang Dui. Although he had never met Yang Nong during this period, he also knew that Yang Nong had always been anxious to go to Qingtian County. After all, promoting high-yield crops was his greatest effort in his life, and he also liked to take everything on himself, so his current reaction was also unexpected to Li Xiu.

"Although smallpox is controlled now, no one dares to say that there is no danger of erupting. What's more, the yield of cowpox is so low that it is impossible to plant it for everyone, so the danger of smallpox has never passed." Yang Nong smiled at this time, and after a moment, he spoke, "I am old and have seen through life and death. However, Dui'er is still young and has a young child at home. In addition, I believe in his ability, so he will definitely not be worse than what I do when he goes to Qingtian County."

After hearing this, Li Xiu couldn't help but smile bitterly. Unexpectedly, Yang Nong valued Yang Dui so much. But it was not surprising that Yang Dui was raised by him and was no different from his son. Moreover, Yang Dui was the most promising among Yang Nong's sons and nephews, so he naturally put all his efforts on cultivating Yang Dui.

"Okay, but I guess Yang Dui knows that if you give him this opportunity, he may not be willing to accept it, right?" Li Xiu nodded first, then asked Yang Nong back, Yang Dui's character is indeed good and he is very filial to Yang Nong, so in this kind of thing, he would never agree to accept Yang Nong's kindness.

"Haha, it's actually simple, so I naturally have a way to get Dui'er to agree!" Yang Nong smiled at this time, and after he said that, he asked someone to call Yang Dui over.

"Uncle, do you have any instructions?" Yang Dui immediately spoke when he came to Yang Nong.

"Di'er, the prince-consin brings a portion of cowpox powder. Now you can ask him to help you plant cowpox, and then go to Qingtian County to check the growth of those crops!" Yang Nong pointed at the porcelain bottle in front of Li Xiu with a serious expression and said.

"Vaccinola powder?" Yang Dui's eyes lit up when he heard this. He was about to nod, but then he asked Yang Nong again, "Uncle, do you only have one coaccinola powder? What should you do?"

"Well~, there is only one portion, and in a short period of time, our agricultural department only has this portion, so those who grow cowpox must go to Qingtian County, and may have to live there for a while. After all, it has been so long, and no one knows how the corn and sweet potatoes in Qingtian County look like. If there is any problem, this person needs to solve it. But I am old now and my energy is not as good as before. You will never bear to let me, an old man in my seventies, go to Qingtian County alone, right?" Yang Nong coughed and said with a faint smile.

"This..." I have to say that Yang Nong's eloquence is really amazing. He suddenly gave Yang Dui a reason to refuse. Even Li Xiu secretly gave Yang Dui a thumbs up. In the end, Yang Du had to agree, and Li Xiu also vaccinated him with cowpox here directly.

"Mr., after planting cowpox, how many days will it take to avoid being afraid of smallpox?" Yang Nong asked Li Xiu again at this time.

"I originally thought that after planting vowel, I needed to scar the wound to avoid being afraid of smallpox, but Master Sun found that planting vowel can actually treat smallpox, so Yang Dui could go to Qingtian County at any time." Li Xiu replied with a smile. As long as you plant vowel in time, you can even treat smallpox. Now, you naturally don't have to worry about smallpox if you plant vowel first.

"That's great. Why don't the prince-in-law send Yang Du to Qingtian County today? After all, corn and sweet potatoes are not waiting for others. It's a little earlier!" Yang Nong immediately stood up and urged. The words he said to Yang Du just now were not all fake. After all, he is too old and his energy is not as good as before. Sometimes he is worried that he can live until the day when everyone in the world eats corn or sweet potatoes?

"This... OK, then Yang Dui, clean up, I'll take you in!" Li Xiu was stunned when he heard Yang Nong's words, and then nodded with a bitter smile. He could understand Yang Nong's mentality, but this mentality might not be a good thing. After all, it is easy to make mistakes if you are too hasty. However, it is not easy to persuade you now. You can find an opportunity to have a good chat with Yang Nong in the future.

Yang Dui seemed to have been used to his uncle's decisive attitude. He immediately agreed and ran out. After a while, he came with the bedding. It seemed that he had also made plans to live in the Qingtian County Magistrate.

At that moment, Li Xiu took Yang Dui to Yang Nong and took him to the military camp where Li Xiu lived before. It was actually the border of Qingtian County, and Fang Xuanling was also there. After Li Xiu explained the purpose of his visit to Fang Xuanling, the other party hesitated and agreed. After all, the growth of corn and sweet potatoes is also very important, and Yang Dui will not leave for a short time after he goes to Qingtian County.

"Fang Xiang, Yang Dui has only one person. It would be unsafe to go to Qingtian County alone. Can you send someone to escort him?" Li Xiu asked at this time. Since the smallpox eruption, the county magistrates of Qingtian County have died of illness. Some people with smallpox erupted in despair. Many evil things have occurred, so Li Xiu was worried about Yang Dui's safety.

"Haha~, it's a coincidence that Master Sun and his friends have started vaccinating vaccinated with cowpox in Qingtian County. The cowpox powder they brought has been used almost all. Today, they sent someone to transport a batch of cowpox powder to the county town. I heard that they were still county magistrates of Qingtian County, and they also brought dozens of soldiers. It just so happened that the official from the Ministry of Agriculture could go to Qingtian County with them!" Fang Xuanling also smiled at this time.

"That's great, but can I meet that county lieutenant? After all, after Yang Dui went to Qingtian County, he would definitely need the county officials to help do some things, so I would like to explain some things to this county lieutenant in person!" Li Xiu immediately said in surprise when he heard this. Yang Dui would definitely not be able to do anything by himself, and he must also need the assistance of Qingtian County Government. However, the county magistrate died of illness, and the only remaining were the county magistrate and county lieutenant. He could just explain it so that the other party would not cooperate with Yang Du.

"No problem, I will send someone to call the county lieutenant!" Fang Xuanling agreed readily. Then he ordered his men to call people.

After a while, a tall and thin young official strode, with a long face, square mouth and straight facial features, short beards under his jaw, and looked shrewd and capable. When he saw Fang Xuanling, he immediately bowed and said, "Qingtian County Magistrate Liu Rengui, pay homage to Fang!"

"Liu Rengui? Why is this name a little familiar?" Li Xiu suddenly clenched his ears when he heard this, and felt like he had heard this name somewhere?
