Father can be an enemy to the country

Not far from Dagongfang is the Prince Zhou's Mansion.

When Zhu Zhen came over, it was already dark...

Einstein's theory of relativity does not mean that time will fly when you are with the person you like. So it was not that he was delaying on purpose, but that he had arrived here unknowingly.

After the announcement, the fifth brother came out to greet him and said with a look of resentment: "I heard that you left my elder brother's place in the morning, and I asked your sister-in-law to prepare lunch."

"Ah? Really." Lao Liu scratched his head in embarrassment and said, "I stopped by to see Gao Chi. The kid is so cute. I was late playing without even realizing it."

"Isn't it cute to have stew in my house?" Fifth Brother said even more resentfully.

He gave birth to his eldest son on the thirteenth day of the first lunar month, but because of the death of his uncle, no one paid attention to him at all.

It was not until a few days ago that Zhu Yuanzhang, at the urging of Empress Ma, gave the fifth eldest son the word "stew".

Coupled with the seniority poem of the King of Zhou, "There are sons who live in peace and harmony, diligent court is solemn and respectful, Shaolun is beneficial and nourishing, Zhaoge is wide and worthy of Yong", the eldest son of the King of Zhou, who is already one month old, finally has a name - Zhu You stew.

"Of course Youdou is very cute." Zhu Zhen said with a smile: "Shouldn't I just come to play with him?"

"You should call him by his full name." King Zhou had always been depressed. He always felt that this name sounded like 'You Dun'er', which made people feel appetizing.

Lao Liu quickly comforted him and said, Zhu Youdou is very good, better than Zhu Shangkang from the second brother's house.

Fifth Brother was no longer sad, and looked at Lao Liu with a cheerful face:

"In the fourth brother's family, the cutest one is probably not Gao Chi." He and the fourth brother are siblings, what don't they know? "It's a pity that my father-in-law only has one daughter..."

"Hehe, why don't you tell the truth when you see it." Lao Liu smiled and hugged the fifth brother's shoulders and said, "Everyone of you is married, established a career and is a father. My brother, I am still single."

"It's not easy for you to do both. I'm afraid you'll have to think twice." Fifth Brother sneered.

"Ouch, my brother, why is this mouth so powerful?" Lao Liu laughed loudly and said, "This little idiom is used, and you still have to think twice."

"I thought of this word years ago, and I just said it today." Fifth Brother said honestly.

"Hahaha." The two brothers put their arms around each other and laughed.

~~

While talking, Zhu Zhen went into the main hall and paid homage to his fifth sister-in-law.

Princess Feng of Zhou was the legitimate daughter of Duke Feng Sheng of the Song Dynasty. Like the eldest sister-in-law, the third sister-in-law, and the fourth sister-in-law, she was the daughter of the general family. Although she was of noble birth, she was not arrogant, heroic, and generous.

"Uncle Six is ​​finally here. If you don't come, this family will be broken up." As soon as Mrs. Feng saw the 'friend of the sisters-in-law', she pulled him to vent her bitterness.

"Is it that serious?" Lao Liu was also shocked. It was as difficult to break up a house for a prince as it was to marry a prince.

"It's not that serious, just listen to her fuss." Fifth Brother said sarcastically.

"Why is it not that serious? Then I am going to complain to my father, why are you stopping me?" Feng raised her eyebrows, not afraid of Lao Wu at all.

"It's such a trivial matter, there's no need to alarm father." Fifth Brother said with a bitter smile.

"It's a small thing?" Feng said angrily: "You are still so young, so you have to leave us and go to Ningguo. If you never come back, how will we survive?"

After saying that, he turned away and wiped his tears with his sleeves.

"Hey, aren't we going to Ningguo? We're not going to England. Why can't we come back?" Lao Liu asked in confusion.

Ningguo Mansion was under the jurisdiction of Zhili, and it was located in Anhui Province in later generations. As soon as you heard it, you knew that it was not far from Nanjing.

"I felt the same way at first, so when he said he would go to Ningguo to collect medicine, I didn't stop him. If my uncle hadn't passed away, he would have been there by now." Feng sobbed:

"I heard someone accidentally mentioned the day before yesterday that there was a smallpox outbreak there, so I stopped him from going, but he insisted on going. Uncle Liu, you judge, he insists on going to a place where others can't hide. Are you crazy to get up on the pole and move around?"

"I have told you so many times that I will not get smallpox." Fifth Brother said decisively: "I have already vaccinated myself with pox!"

"Ah?" This time it was Lao Liu's turn to be shocked. He looked at Fifth Brother with dumbfounded eyes, and then looked at Fifth Brother's arm.

Zhu Rui nodded slightly and said sternly to Feng: "Let's talk to Lao Liu alone. If I can convince him in the end, you let me go. If he stops me, I won't go."

"Fuck, no..." Lao Liu couldn't stand it anymore. Wasn't he making himself a bad person?

"Okay, I trust Uncle Six." Feng nodded. There is no way, who made the sixth brother's reputation among the sisters-in-law too good?

"Uncle Six, for the sake of You Duo'er, you must stop him." She begged Lao Liu again.

"Ah, I'll try my best." The sixth brother was speechless. The fifth brother was really merciless when he tried to trick his brothers.

~~

So, not caring about food, the fifth brother took Lao Liu to an independent courtyard in the back garden of the palace.

He took out the key, opened the door and said: "It's still the same as in the palace, no one can enter here."

"Well, in the laboratory, no one should be allowed in." Lao Liu said, then he took out a big mask and put it on. He even put on a pair of gloves like a magic trick.

"Don't worry, there is nothing here that can be infected with pox." Fifth Brother knew what he was worried about.

"Hehe..." Lao Liu smiled, but still refused to take off the protection, and asked curiously: "Have you really been vaccinated?"

"Is there any falsehood?" Fifth Brother rolled up his sleeves, and a small daisy-like scar suddenly appeared on his arm.

"Fuck, Niu Boyi..." Lao Liu raised his thumbs with both hands, but his toes were actually standing up.

"It's not cowpox, it's cowpox." Fifth Brother said seriously: "After you said that cowpox can be used to replace variolation, I have been researching it and finally reached this step."

"Fifth Brother, you... are so awesome." Faced with Fifth Brother's feat, Lao Liu was completely at a loss for words. I can only use those two words repeatedly to vent my emotions.

~~

Speaking of which, Lao Liuqi started this matter.

Many years ago, when the two brothers were still living in the palace, they often lay up all night talking about human hygiene, that is, medical topics.

Although Lao Liu has never studied medicine specifically, he can still shamelessly say that no one in the world understands medicine better than him.

Of course, he could only talk about it, but if he really wanted to do it, there was nothing he could do. Therefore, he is responsible for opening the door to the new world for the fifth brother, and then letting the fifth brother dive in, explore and research.

Among them, the one door that he attaches most importance to is the prevention and control of smallpox.

There were three major infectious diseases in this era: plague, smallpox and cholera.

The former is prone to occur in the north, while the latter is prone to occur in Lingnan, which is relatively far away from him.

The closest thing to him was smallpox. His ninth brother Zhao Wangqi died of this disease. At that time, there was a big outbreak of pox in the palace. Hundreds of palace residents, including Zhu Qi's mother and concubine, were sent to the Inner Hall and never came out again.

And he speculated that a few years later, the hero and his mother probably died from smallpox...

Otherwise, it would be difficult to explain why the old man and the young man died suddenly one after another in a short period of time.
