The ministers begged me to ascend the throne

Zhao Yao, who was far away in Lingnan, received a letter from King Chu. In the letter, King Chu told Zhao Yao that King Zheng was about to return to the capital from Jiaozhou.

After Zhao Yao received the letter, he immediately sent someone to tell Princess Annan about the matter. After Princess Annan learned about it, she came to Marsh Mansion to find Zhao Yao in person. She came to Marsh Mansion quietly, and then left without a trace.

"What did you say to Princess Annan?" He Lianfang was not present when Zhao Yao was talking to Princess Annan.

"I told her everything that King Zheng has done in Jiaozhou over the years. As for what she will do after arriving in the capital, I don't know." What King Zheng has done in Jiaozhou over the years can be described in one word ——There are too many books to write.

He Lianfang asked: "You didn't give her any advice?"

Zhao Yao shook his head slightly: "No, she doesn't need me to help her with advice." Princess Annan hated King Zheng so much that she probably simulated revenge on King Zheng many times in her mind over the years.

"Anyang Gongfu is not a vegetarian. Do you think she can succeed?"

"It is indeed difficult for her to seek revenge from King Zheng on her own, but Fourth Brother and Eighth Brother will help her secretly." Zhao Yao said with a smile, "The reason why Fourth Brother proposed to Father to let King Zheng return to the capital is because Get rid of King Zheng.”

"Why do King Chu and King Wei hate King Zheng so much?" Although King Zheng and King Chu were rivals for the throne, so were King Dai and King Jing. Neither King Chu nor King Wei wanted to kill King Zheng. .

"Of course it's because of what King Zheng did."

He Lianfang didn't believe it, "What King Zheng did did not hinder King Chu and King Wei. Has King Zheng offended them before?"

"I don't know, maybe." Zhao Yao had asked King Chu and others about this before, and they all said that King Zheng was unworthy and deserved to die.

"Does it have something to do with you?" He Lianfang intuitively felt that King Chu and the others had always wanted to kill King Zheng, and there must be other reasons. The reason why the King of Chu and the King of Wei could hate him so much at the same time probably had something to do with Zhao Yao. Only things related to Zhao Yao would make King Chu and King Wei so angry. "Did you have any issues with Prince Zheng?"

"Is it related to me?" Zhao Yao looked surprised, and then said innocently, "I have no enmity with Prince Zheng."

"It really has nothing to do with you?"

"No, it has nothing to do with it at all." Zhao Yao said, "For the things that King Zheng did, I wanted to kill him. There is nothing strange about Fourth Brother and Eighth Brother wanting to get rid of King Zheng."

He Lianfang felt that Zhao Yao's words made some sense, so she stopped talking about this matter and changed the subject to talk about other things.

"Is the pistol ready?"

"It's almost time." Zhao Yao smiled bitterly, "Second uncle, please don't rush me. The people over at Beishan have been doing it and haven't been lazy."

"It better be this way."

At this moment, Tongxi hurriedly walked in. He ignored the salute and said hurriedly: "Your Highness, the Nanshan Farm said that cowpox was successful, and they asked you to go and have a look."

"Vaccinium was successful?" Zhao Yao shouted with surprise on his face.

"That's what the person who came here said."

"I'll go over now." Zhao Yao was so anxious that he didn't even say hello to He Lianfang and hurried out.

Nanshan Farm is a bit far away from Prince Han's Mansion, and it usually takes an hour to arrive, but Zhao Yao was in a hurry to get there, and he rushed all the way, and arrived in half an hour.

When Doctor Tong saw Zhao Yao, he was about to salute when Zhao Yao helped him up.

Zhao Yao asked eagerly: "Tell me what's going on?"

Next, Dr. Tong told Zhao Yao the details of the cowpox vaccination.

For this cowpox vaccination experiment, Zhao Yao asked Dr. Tong to conduct separate experiments according to age. For example, from six to ten years old, eleven to fifteen years old, sixteen to twenty years old, twenty to thirty years old. Forget it if you are over thirty years old.

Of course, the people who participated in the cowpox experiment were slaves of the Japanese country. It would be no shame if they died during the vaccination. It would be too cruel to use the people of Marsh Mansion for experiments.

During these days of cowpox experiments, more than ten or twenty slaves died, and many slaves were seriously ill. Fortunately, it finally succeeded.

Dr. Tong and others carefully recorded each person's reaction after being vaccinated with cowpox, as well as their physical condition after successful vaccination.

Zhao Yao looked at the records of Dr. Tong and the others in detail, and after reading them, he praised: "You have done a very good job. You have made a great contribution this time, and it is a great contribution to the world."

"It's all my fault, Your Highness."

"I'm just telling you my ideas, but you did the experiments." Zhao Yao said with a smile on his face, "You guys have been taking risks to do experiments during this period. It's really hard and amazing."

Hearing what Zhao Yao said, Doctor Tong was very moved. His eyes were red and filled with tears, and his voice was choked with sobs: "Your Highness, this is what I should do."

"I will truthfully report to my father what you have done during this period. I think your father will definitely reward you." Zhao Yao added, "Of course, I will also reward you."

Doctor Tong said excitedly: "Thank you, Your Highness."

"Successful vaccination against cowpox will save the lives of many people in the future. This is a great merit. You must leave a lasting mark in the history books."

"Your Highness, this is all thanks to you. If it weren't for you, I wouldn't be able to cure cowpox." As doctors, they never thought of vaccination to prevent smallpox, but His Highness did.

"You write a detailed memorial to vaccinate against cowpox, and I will send it to the capital when the time comes."

"Yes, Your Highness."

"By the way, my father may ask one of you to return to the capital. Let's see who will be sent back to the capital to teach the imperial doctors how to vaccinate cowpox." After Zhao Yao finished speaking, he suddenly remembered something and said, "If any of you want to Go back to the capital and tell me, I won't stop you." Dr. Tong was shocked when he heard this. He hurriedly said: "Your Highness, I am by no means an ungrateful person, and I have no intention of returning to the capital. I was framed and ostracized at the beginning and could not survive in the capital. It was you who took me in and trusted and valued me. I am willing to follow you all the time."

"You misunderstood me..."

Dr. Tong interrupted Zhao Yao rudely, "Your Highness, although the capital city is prosperous, I don't want to go back. I have fallen in love with it since I came to Lingnan. I also want to build a hospital with you and start construction." The medical school teaches the people of Lingnan to learn medicine. You must not leave me alone."

"Since you don't want to go to the capital, then stay in Lingnan." Zhao Yao said with a smile, "I hope you will stay in Lingnan and help me build hospitals and medical schools."

"Your Highness, don't worry, I will never leave Lingnan."

"You select two people, and then go to the capital to teach the imperial doctors to vaccinate against cowpox." Although the memorial will describe the process of vaccinia in detail, it is necessary to arrange for experienced doctors to return to the capital. Teach the doctors step by step, otherwise they will have to figure it out on their own without knowing what may go wrong. "After the cowpox vaccination is successful, don't rush back to Lingnan. Go home to reunite with your relatives first. When I return to the capital next year, you can come back to Lingnan with me."

Doctor Tong looked surprised: "Your Highness, you are going back to the capital next year. What are you doing back in the capital?" He remembered that the prince had gone to the fiefdom, and he could not leave the fiefdom without the emperor's summons.

"Getting married." Zhao Yao said with a helpless face, "I will return to the capital next year to get married."

Doctor Tong then remembered that their Highness was not married yet, "It's time for His Highness to get married, and it's time for the Han Dynasty's palace to have a mistress."

Zhao Yao waved his hand, not wanting to talk about his marriage anymore.

"Since the vaccination against cowpox has been successful, children will be vaccinated against cowpox starting from tomorrow." There is no need for adults to be vaccinated against cowpox. Even if it is planted, it will have no effect. It is more useful to vaccinate children with cowpox. “You can plant them until you reach adulthood.”

"Yes, Your Highness."

"By the way, the vaccination against cowpox has been successful. Next, you can make pills for worming." When it came to worming, Zhao Yao thought of the children he saw a few days ago...forget it, let's not mention it. , otherwise he will feel sick again. "Now that sugar is available, you can try adding sugar to the pills, so that the children will like to eat it." There are many snakes and insects here in Lingnan, and due to the warm climate, there are many parasites, so here There are many worms in the stomachs of the people.

Although you can drink medicine to fight insects, it is really too bitter to drink. Zhao Yao wanted to make the pagoda candy from Zhao Yao's world in his dream. Sweet pills, kids will definitely love them.

"Yes, Your Highness."

Zhao Yao explained a few more words before leaving the farm in Nanshan. He did not return to the Han Palace, but went to Beishan.

He went just in time. Beishan's craftsmen successfully made a pistol, and after several experiments, it was more flexible and easier to use than the previous firecrackers, and the accident rate was less than that of firecrackers.

Originally he planned to stay in Beishan and go back in a few days, but thinking that He Lianfang and Uncle Gao had been waiting for the pistol, Zhao Yao hurried back to the Han Dynasty Palace with the prepared pistol.

He Lianfang had been waiting for Zhao Yao. When he saw him come back, he hurriedly asked him: "Is that cowpox you are talking about really successful?" He had heard Zhao Yao talk about the cowpox vaccination experiment before, and he knew what the success of cowpox vaccination meant.

"It's successful, very successful. Children who are six years old or older will be vaccinated against cowpox starting tomorrow." Zhao Yao said with joy on his face. "After being vaccinated with cowpox, the children will not get smallpox again."

"Only for children, what about adults?"

"Adults don't need to plant it, and it won't have any effect if they do. It's better to plant it for children."

He Lianfang nodded and said, "It's also good to plant seeds for children."

"Another good thing happened. Second uncle, guess what it is?"

He Lianfang thought that Zhao Yao had gone to the farm in Nanshan, and guessed that the good things must be related to the farm.

"Did you let the silkworms raised on the farm spin silk?"

"No." Zhao Yao did not tease He Lianfang, but directly took out two pistols from the backpack on his waist and placed them in front of He Lianfang. "The pistol is made."

The moment He Lianfang saw the pistol, his eyes suddenly brightened, and his expression became very excited. He hurriedly picked up a pistol, looked at it carefully, and then asked Zhao Yao to push him to the yard, where he wanted to try the pistol.

"Second uncle, what do you think of the pistol?"

He Lianfang couldn't put it down and said: "It's great, it's really great!"

Seeing that He Lianfang loved pistols so much, Zhao Yao was also happy.

"This is the first version, and it will be improved later." The current pistol is still a bit big, and it will need to be improved and made smaller in the future.

"Is this still the first edition?" He Lianfang was shocked.

"Yes, it can be improved, and it will be more usable than the one you have now." Zhao Yao thought of the cost of making a pistol, frowned slightly and said, "The cost of making a pistol is too high, so we should make less in the future, or Let’s make more firecrackers.”

"It's up to you." He Lianfang had already obtained the pistol and no longer urged Zhao Yao to make an improved version.

"I want to write a memorial to my father. I hope you go and find Uncle Gao." These days, Uncle Gao has been urging him to make a pistol. Now that it is made, he must give it to him as soon as possible.

Half an hour later, Uncle Gao returned to Prince Han's Mansion. After seeing the pistol, he kept shouting excitedly in the yard. Like He Lianfang, he couldn't put it down. During dinner, he would take it out from time to time to look at it, touch it, and kiss it.

Fortunately, the bullets in the pistol were all used up, otherwise Zhao Yao was really worried that Uncle Gao would make the gun go off if he held it like this.

The emperor who was far away in the capital received a memorial from Zhao Yao. This memorial states that he successfully diverted water from Marsh Lake to Marsh Mansion, and then proposed to use this water diversion method on the West Lake in Quanting County.

After the emperor read it, he immediately called the Minister of Industry.

After reading Zhao Yao's excerpt, Minister of the Ministry of Industry, his hands trembled with excitement, and he kept praising His Highness the King of Han as a genius.
