Lan Xiaoyou pulled his thoughts back from the memories of his previous life, and said to Lan Xiaoqin: "Second brother, don't complain, if I don't follow the villagers around, how can I know about cowpox?" ”

"Can this cowpox really prevent smallpox?" Lan Xiaoqin asked.

"Well, I went to several nearby villages and found that almost all the cattle farmers had pox, and the symptoms were the same as those of smallpox, but they were almost ten times lighter, and they were cured in two or three days. People who are in good health, even if they only have a few pimples, will pass without a fever. ”

Lan Xiaoqin was excited when he heard this, and stood up: "I'll find someone to study it immediately." ”

After saying that, it was like installing hot wheels on his feet, and he ran out in a blink of an eye. He wanted to go to Huang Furui first, and then send someone to test the authenticity of cowpox to prevent smallpox...... Oops, it's so busy.

Lan Xiaoqin didn't take the carriage, and rode directly to King Kang's mansion. The Jingyuan Marquis Mansion and the Kang Wangfu are not far away, Lan Xiaoqin often comes to the Kang Wang's Mansion, and the gatekeeper saw Lan Xiaoqin coming on a horse, knowing that he had something important to find his own prince, so he quickly opened the side door and let Lan Xiaoqin ride directly into the mansion.

Lan Xiaoqin rode all the way to the outside of Huang Fu Rui's study and stopped, jumped off the horse, and strode towards Huang Fu Rui's study.

"What made you so anxious that you ran into my palace?" Huang Furui put down the brush in his hand and looked up to ask Lan Xiaoqin. The beautiful maid beside him who was grinding ink glared at Lan Xiaoqin unwillingly and vaguely, but Lan Xiaoqin didn't notice it.

"Well, take a look at it first." Lan Xiaoqin took out a piece of paper from his arms and handed it to Huang Furui.

"Is this a doubt?" Huang Furui looked at the results, "Cowpox? What is it? ”

"Ways to control smallpox." Lan Xiaoqin walked to the chair next to him and sat down, lifted the kettle, poured himself a glass of water, and drank it. This work should have been done by the maid who served in the study, but it seemed that the maid had forgotten her duty. Lan Xiaoqin couldn't help frowning, and glanced at the beautiful maid standing beside Huang Furui. In the past, he didn't think there was anything wrong with this picture, but today he felt that it was an eyesore.

"What?" Huang Furui got up from his chair in shock, and asked with wide eyes, "Really?" You're not kidding me, are you? ”

"Of course it's true. This method was discovered by the third sister, and after investigation, at least eighty percent of them are sure that it is true. The remaining two percent, they will ask us to find someone to verify. ”

"It's a credit to Xiao Yu again." Huang Fu Rui was very happy, "How can I Huang Fu Rui, be able to get this virtuous help?!" ”

"My sister hasn't married you yet!" Lan Xiaoqin and Huangfu Rui quarreled, his eyes swept to the beautiful maid, and seeing the jealousy and unwillingness in her eyes, Lan Xiaoqin's brows furrowed.

"Let's go, let's go verify it right away." Huang Furui couldn't wait to verify the feasibility of cowpox prevention and control of smallpox, so he pulled Lan Xiaoqin out of the study, and made the beautiful maid in the study stomp her feet angrily. Obviously, the prince was going to stay in the study for half a day, but he was seduced away by Lan Xiaoqin in less than an hour, and sure enough, the surname Lan was so annoying.

"Your Highness, that maid in your study......"

Huang Furui would be mistaken, and he smiled without listening to Lan Xiaoqin's words: "What? Fancy it? Then I'll give it to you. ”

"No, no." Lan Xiaoqin hurriedly refused, "That maid takes a fancy to your Highness, if Your Highness gives it to me, then the maid doesn't resent me to death?" For the sake of my little life, let's forget it. ”

"But a little girl, are you still afraid?" Huang Fu Rui smiled.

"If it was before, I would not take these maids in my eyes like you, but what happened in my family these days makes me have to pay attention to some thoughtful maids, so as not to know if they will be killed one day."

"What is it that makes you so angry?"

"Cong'er had smallpox a few days ago, it was man-made, and it was a ghost caused by two subordinates. One of them was my mother's personal maid, and the other was my eldest brother's former maid. Both of them were interested in my eldest brother and jealous of my sister-in-law, so they hit Cong'er with their ideas. I wanted to kill Cong'er, Cong'er took revenge on my sister-in-law, and then instigated my mother to give one of them to my eldest brother and be my eldest brother's woman. Lan Xiaoqin's face became serious, "Your Highness, don't underestimate any woman, for the sake of status and the favor of men, they can do anything." ”

"Those two women are amazing!" Lan Xiaoqin's words attracted Huang Furui's attention a little, and he murdered the eldest grandson of the first house, those two women were really daring. He couldn't help but think of the various frames he had encountered when he was still in the harem, the women in the harem are not simple, but the maids of ordinary people are simple?

"Xiyu has been by my side for a few years, and she understands her identity and will not do anything to endanger her master like the two maids in your house." Huang Furui spoke for the beautiful girl in the study, and he was quite satisfied with this girl.

Lan Xiaoqin said: "When Zhao's second daughter-in-law was by my eldest brother's side, my eldest brother was also very satisfied with her; Qingxue has to be relied on by my mother, and my mother's evaluation of her is also sensible and measured. ”

"This ......" Huang Furui didn't think he would look at the wrong person, he had always trusted his own vision.

Lan Xiaoqin: "When you mentioned the third sister just now, I saw jealousy and hatred in the maid's eyes. ”

Huang Furui still believed Lan Xiaoqin's words very much, he didn't think that Lan Xiaoqin would eliminate his rival in advance in order to help his sister. After all, even if he can't be the emperor in the future, he will have side concubines and concubines, and it is impossible to have only one wife for Lan Xiaoyou. can only show that Xiyu really showed something wrong, and Lan Xiaoqin will remind him.

Huang Furui sighed: "No wonder my mother handed over the entire backyard to the princess to manage after I got married, I think my mother doesn't believe my eyes on people." After all, this girl has served me for a few years, and I will arrange for her to marry another person when the time comes. ”

Lan Xiaoqin said faintly: "My sister-in-law also arranged for Zhao's second daughter-in-law to marry someone else, and the result, you see." ”

Huangfu Rui glanced at Lan Xiaoqin: "You can't let me kill Xiyu, right?" ”

Lan Xiaoqin laughed: "How come." You can do whatever you want with your people, it's not for me to interfere. ”

Huang Furui snorted, and decided to send Xiyu to Zhuangzi, which was five hundred miles away from Beijing, after returning home, and would not let him return to Beijing for the rest of his life.

Lan Xiaoqin looked at his expression, and was proud in his heart: Sister, my brother helped you get rid of an enemy in advance! How do you thank your brother?

If Lan Xiaoyou heard Lan Xiaoqin's heart, he would definitely give him a big slap: Xiyu, this woman was also one of her enemies in her previous life, how could she let it go so easily?
