Traveling through time with a house, I teach people all over the country how to farm

The three of them bowed and said, "I'll take my leave!"

Emperor Yongshun nodded and said, "Zhen'er, you haven't left the house for half a year. Stay and talk to me."

The third prince Sheng Zhen continued to bow: "Your son obeys your order!" Then he returned to the chair he had just sat on.

Emperor Yongshun looked at the people and asked Minister Zhong: "My dear, what other property do I have to sell?"

Minister Zhong glanced at the emperor, who seemed to be in a very good mood and was even joking with others.

Minister Li also said, "There are a few houses in the inner city of Beijing. They were taken back when the houses were sealed last year. They are not very suitable. The courtyard next to the Third Prince's Mansion is a bit big. The people living nearby are all princes and first-rank officials. There are also a few smaller houses in the south. What do you think, Your Majesty?"

Emperor Yongshun is now certain that Zheng Sisi is the lucky star. No wonder the old bald don’t know who she is. She has changed her name, so what can he know?

This girl has done nothing, so the house cannot be given to her. She can only sell it at a low price. Where should she sell it? It can't be too far away, and it must be convenient to take care of and summon. I glanced and saw my third son drinking tea. Isn't it enough?

Emperor Yongshun applauded his own wit.

Emperor Yongshun looked at Zheng Sisi and said, "Zheng girl, how much money do you have to buy a house?"

Zheng Sisi choked and said aggrievedly: "I don't have the money to buy a house for now. I won't know how much I have until they send it to me."

Several people laughed at the same time.

Zheng Sisi embarrassed.

Emperor Yongshun kindly said, "Well, I will sell you the house next to the Third Prince's Mansion, and you can give me 10,000 taels of silver."

"Ten thousand taels, so much!" Zheng Sisi was shocked.

Minister Zhong said anxiously, "It's more than ten thousand taels. This house should be worth fifty thousand taels. The emperor charged you ten thousand taels and you still think it's too expensive."

"Ah!" Zheng Sisi opened her mouth and didn't close it for a long time.

Emperor Yongshun said: "How about this, it's still 10,000 taels, you can pay it back slowly."

Zheng Sisi said, "Is it okay?"

Emperor Yongshun said, "Yes."

Zheng Sisi said: "But I am afraid of being in debt. Can I exchange it for something else?"

"Hey," Emperor Yongshun was unhappy, "Others who want to owe me money have no chance, and now I give it to you and you don't want it."

Zheng Sisi shrank her neck.

The two ministers also looked at Zheng Sisi as if she were a fool.

Only the third prince was still leisurely drinking tea. He felt that this girl was not simple and he couldn't see through her.

Emperor Yongshun asked again: "What are you going to give me in exchange?"

Zheng Sisi said, "I'll trade you a recipe."

Emperor Yongshun: "What kind of prescription is so valuable?"

Zheng Sisi: "Your Majesty. How about you ask someone to get some materials and I'll make it for you. If you think it's okay, we can change it."

"Okay, what materials do you need?"

Zheng Sisi walked to the table where Xie Junru had written the letter of severance, picked up a pen and wrote two words: "Saltpeter".

Several people came over to take a look, and were puzzled after seeing the two words.

Zheng Sisi handed the paper to the emperor with both hands and said, "Your Majesty, you can find out what the prescription is if you ask someone to get saltpeter. This saltpeter can be bought at any clinic or drugstore."

Emperor Yongshun was half-believing and half-doubting. He called a guard and asked him to go to the Imperial Hospital to get some saltpeter, and told him not to let anyone know about this.

Zheng Sisi had already thought about it, her identity change would require a background, and she would have many strange and weird things to bring out in the future.

Today, I will reveal that she has a mysterious master in the countryside. This is what she learned from a time-travel novel. The mysterious master in the novel is omnipotent. She has made saltpeter into ice, and anyone who has doubts about it can find the source.
