The journey of the heavens by Jia Huan, the salted fish

Du He came to find Fang Yiai, besides visiting his friends, he also had business to do.

Some time ago, one of Lu Shi's favorite clothes was heavily stained with oil, and couldn't be cleaned with bath beans.

Jia Huan took out the soap and the method of making soap.

Lu made a batch of soap and scented soap, kept some for his own use, and gave the rest as gifts to some noble ladies he knew.

Among them is Mrs. Du.

Du He got a piece of soap from his mother, and after using it, he found that the cleaning effect of this thing was very good, so he had an idea in his mind.

Du He is the second son in the family, and most of the family business will be inherited by his own elder brother.

There is a younger brother under Du He, and he wants to share the rest of the family business with his younger brother.

How much property can he get?
How much will you leave to your descendants in the future?
Du He was very concerned about this, he wanted to make money, and wanted to accumulate a fortune for himself.

Du He started doing business a few years ago, and there are several of his shops in Chang'an City.

Du He was looking for Fang Yiai this time, because he wanted to learn about the making of soap from Fang Yiai, so that he could get Fang Yiai to join his business and make money together.

Fang Yiai's heart was moved after hearing this, she wants to make money by herself!
However, Fang Zi was given to A Niang by my younger brother, so he can't give it away.

At least ask A Niang and younger brother for their opinions first.

"This recipe belongs to my mother, I have to get my mother's consent first."

"Okay, then I'll come see you tomorrow."

After Du He left, Fang Yiai hopped to Lu's yard.

Jia Huan happened to be in Lu's courtyard. Hearing Fang Yiai's words, Jia Huan smiled: "It's just a small prescription. If you want it, you can use it."

Lu Shi also nodded: "It's just right, you can also drum up some of your own property. When your shop starts selling soap and scented soap, my side will also feel relaxed."

Otherwise, it would be very annoying for a group of noble ladies to ask her for soap every day.

Fang Yiai had a sore nose.

His younger brother and mother were too kind to him.

In his previous life, he was really not a thing. He contradicted A Niang for that woman Gao Yang, and separated from his brother.

Hey, by the way, did I have a younger brother Fang Yihuan in my previous life?
No!

Fang Yiai's eyes widened.

The biggest difference between the previous life and this life is that I have an extra brother in this life!
Could it be that this younger brother was specially sent by God to protect Fang's family?
It is precisely because of the younger brother that the Fang family can obtain high-yield crops such as sweet potatoes and a new method of oil extraction.

Only these two contributions made the Fang family invincible.

And because of the younger brother, the woman Gao Yang was demoted to the princess, life is much more difficult than before.

At least Emperor Li Er no longer spoiled her as before.

Fang Yiai felt that her younger brother was really a lucky star.

In the future, we must please the younger brother more!

Fang Yiai thought.

The next day, Du He came to Fang's house again.

Fang Yiai readily gave Du He the booklet describing the soap and soap making process.

Du He promised to split the business between the two.

To make it official, Du He also hand-wrote a two-part contract, which he and Fang Yiai signed separately.

More than half a month later, Du He's shop began to sell soap and scented soap.

The price of soap is not high, and many ordinary people can afford it.

The cleaning effect of this thing is really strong. After people use it once, they regard soap as a must-buy daily necessities.

And the nobles are inseparable from soap.

Now one can imagine how good the business of Du He's shop is. It didn't take long for Du He and Fang Yi'ai to become rich.

Du He became more obsessed with making money. He often went to Fang's house, and when he found something new in the room, he asked Fang Yi'ai for how to make it, and then put it in the shop for sale.

Du He's shop has become a must-go check-in point for people in the capital.

Du He was so busy that he didn't have much time to go to the East Palace.

On this day, Du He came to Fang's house again.

Fang Yiai saw Du He and gave him a blueprint.

"What is this?" Du He asked suspiciously.

Fang Yiai: "Take it back to you, Aye. This blueprint has nothing to do with our family."

Du He: "??"

Du He went home with the drawings and went to the study to meet his father Du Ruhui.

When Du Ruhui saw the blueprint, he stood up suddenly: "This old house has given me a great credit!"

Du He nodded. As a well-bred son of an aristocratic family, he can naturally understand drawings and know what is drawn on the paper.

If everyone in the world builds this thing called a kang, in winter, at least [-]% of the people will freeze to death.

Du Ruhui walked around the study excitedly, wanting to promote this blueprint immediately.

However, he couldn't figure out why Fang Xuanling would push this kind of benefit to the country and the people, such a big credit, to himself?

Isn't it good that he took the credit himself?

Du Ruhui couldn't figure it out.

Du Ruhui decided to ask Fang Xuanling the next day why he gave up the credit to himself.

The next day, before he asked Fang Xuanling's reason, he understood.

Fang Xuanling first proposed a matter to Li Er, which is more beneficial to the country and the people than the heated kang, and it is a greater contribution!
The Fang family discovered a high-yield grain variety, with a yield of one thousand catties per mu.

Jack?

What is this concept?
Now that the local grain yield per mu is only more than 200 catties, the grain yield has increased several times.

If the common people grow this kind of food, there will be no more people who starve to death in the world.

No wonder the Fang family wanted to push the credit for the kang to themselves.

Li Er and the other ministers were very excited, especially Li Er, being able to feed the people of the world is the ideal of being an emperor.

Now, this ideal is realized when he is the emperor. Doesn't it prove that he is the eternal emperor chosen by heaven?

Li Er knew that Fang Xuanling would not lie to himself, so he immediately led a group of people to Fang Xuanling's Zhuangzi.

He even dug up a row of sweet potatoes himself.

Fang Xuanling asked the people in Zhuangzi to make roasted sweet potatoes and steamed sweet potatoes for everyone to try.

After everyone ate it, they found that it was not only delicious but also really full, so happy!

Li Er laughed loudly: "With this sweet potato, we don't have to worry about military rations. We can start a war with Tubo and Turks."

Du Ru stepped forward with a dark smile, and presented the blueprint of the kang to Li Er.

Li Er was even more happy after seeing it, and immediately distributed generous rewards to Fang Du and his family.

Both of them are dukes of the state, and their titles cannot be further promoted. Li Er simply came to a hereditary replacement, so that the titles of dukes of the state can be passed down to the children and grandchildren of the two families.

Afterwards, Li Er granted titles to both of their sons except the eldest son. Even a concubine like Fang Yiyi also got a moderate title.

Fang Yiyi was very happy.

Among the masters of the Fang family, he was the only one who didn't know that Jia Huan was still alive, nor did he know about Sweet Potato.

But this guy has a sense of proportion.Even if he knew about the sweet potato, the whole family excluded him, and he didn't complain.

After all, he is just a bastard.
