Princess Qinghe Mansion.

In the hall sat a woman in a green skirt, about fifteen years old, with a delicate pigeon-egg-like face and a pair of black eyes.

The most striking thing is that her hair is actually blonde, with a slight touch of curls.

This is Princess Qinghe. According to Datang's aesthetic standard of 'fat is beautiful', she is a typical ugly girl.

But if Cheng Huailiang, who is a traverser, looks at it, Princess Qinghe's typical beauty, the best Chinese cabbage.

Just after breakfast, Princess Qinghe's mansion ushered in a distinguished guest, a little fat girl about four or five years old, after coming, the little fat girl didn't know what to talk about with Princess Qinghe, and from time to time she let out a series of coquettish smiles.

"Sister Qinghe, brother-in-law is too good." The little chubby girl gave a thumbs up to Princess Qinghe, "He's the only hero I've ever seen." A person who was a strong and rigid imperial historian of the Manchu Dynasty was stunned to win. ”

"Son, don't talk nonsense, my father hasn't set a time yet, he ......" Princess Qinghe's face flushed, "He is not your brother-in-law yet." ”

"Oops." The little chubby girl rushed directly into Princess Qinghe's arms, "It's not a matter of time or time." ”

As he was talking, a Yu Linwei walked in and saluted Princess Qinghe, "Your Highness, Cheng Fu, the chief manager of Chengjiazhuang, came over to give gifts, do you see it or not?" ”

"Let him in." Princess Qinghe got up and sat in the main seat, her appearance was dignified, the majesty of the princess was fully displayed, and she was still holding the little fat girl called Son in her arms.

"Grass people Cheng Fu knocked to see Her Royal Highness the Princess." Cheng Fu got up after giving the salute, "The grass people are ordered by Cheng Xiaogong, the youngest son of Lu Guogong, to present a gift to the princess. ”

"Gifts?" Princess Qinghe and Little Fat Ya were surprised.

"Bring it in."

When the Quyuan plow was placed in the Futang, Princess Qinghe still didn't understand, what kind of ceremony could a tool for plowing the land be?

But the little chubby girl was different, at first she was a little contemptuous, thinking that Cheng Huailiang was too picky, but after looking at it for a while, the little chubby girl's eyes lit up, and she jumped directly into the arms of Princess Qinghe, walked around the Quyuan plow a few times, and suddenly clapped her hands excitedly, "Sister Qinghe, this is a baby, a very big baby." ”

Princess Qinghe stood up and approached Quyuan Plow, she didn't know how to farm, and it was already very good to know Quyuan Plow.

"Cheng Fu, what else did Cheng Huailiang say?" The little fat girl absolutely didn't believe that Cheng Huailiang was just giving gifts.

"And this." Cheng Fu handed over a drawing and taught it to Princess Qinghe, but Princess Qinghe couldn't understand it.

The little chubby girl only found out that this was the drawing of the plow, and she was a little surprised, "It turns out that this is called a Quyuan plow." ”

"I'll say thank you to him when I go back." Princess Qinghe nodded at Cheng Fu, Cheng Fu was about to leave, but was stopped by the little fat girl.

"That's not right." The little fat girl frowned, looked at Qu Yuanli, and then looked at Cheng Fu, "Cheng Huailiang is definitely not a gift, what else did you not say." ”

"Son, don't mess around." Princess Qinghe hugged the little fat girl, "It's just a gift, what other intentions can there be?" ”

"Sister Qinghe, think again."

Princess Qinghe hugged the little fat girl and walked around the Futang twice, she was very confused at first, but suddenly her eyes lit up, and she asked Cheng Fu, "How much?" ”

Cheng Fu smiled and arched his hand at Princess Qinghe, "The little grandfather said, the more the merrier." When Her Royal Highness the princess invests, dividends will be distributed to you every year. ”

"Phew!" The little fat girl was resentful, "Uncle Cheng has no way to teach his son, and the big man has to go to the woman if he wants money, shameless." ”

"Your Royal Highness, the little grandfather also has a hard life, after being kicked out by the old man, he didn't give a penny." Cheng Fu complained to Princess Qinghe for a while.

"I have some savings here, so after noon, you can bring some ox carts here."

How many ox carts? Cheng Fu almost looked at Princess Qinghe with wide eyes, knowing that Princess Qinghe was very rich, but do you want a few ox carts to pull copper coins?

"The money is not taken in vain, and the good dividends cannot be less." Princess Qinghe smiled, "Go back and tell Cheng Huailiang, just say that I accepted the drawings." ”

After Cheng Fu left, Princess Qinghe sent someone to invite the county prince of Huairen, which was in the name of the little son. This stubborn old man is an agricultural maniac, and ordinary people don't move.

There are not many people who are good friends with him, and it just so happens that the little son is one of them.

After the county prince of Huairen came, the little son ran directly to Guo Huairen to hug him, Guo Huairen held the little son in his arms, and there was no way to give a gift to Princess Qinghe.

"Uncle Guo, I want you to help me see a plow." In terms of respect and humility, Princess Li Dexian of Qinghe is a princess, but in terms of seniority, Guo Huairen's daughter-in-law is the fourth sister of the eldest grandson queen, and Li Dexian wants to call her uncle.

"Plow?" Guo Huairen didn't know what was going on, he didn't understand how Her Royal Highness the dignified princess studied the plow.

This is indeed a plow, but this plough is a little invisible. Guo Huairen put down the little son, circled the Quyuan plough twice, and finally simply sat on the ground and studied the plowshare.

As a senior agricultural maniac, he finally studied and understood as the secretary of the agricultural secretary.

"The person who puts the center of gravity at the apex of the curve and holds the handle and handle of the plow can maintain the balance of the plow without any effort."

"The ploughshare can actually move the depth of the soil according to the angle......"

"There's no need to pull a plow with two oxen at all, it's ...... It's just ingenious. ”

The number of cattle in Datang is limited, and there are only about 20 cattle in the homes of big landlords, and the Ministry of Industry, as one of the six departments of the three provinces, can use only 100 cattle for farming.

At the same time and in the same amount, the rate of arable land will directly double. Not to mention the distance, let's just say that around Chang'an City, there are countless wastelands that have not been reclaimed and cultivated land that has not had time to be plowed up.

If this plough is put on the market, every household can use it...... Dasi Nongqing's forehead began to sweat, and he was extremely excited, how important is food to a country? But what if the arable land was doubled, the yield would also be doubled?

Guo Huairen's hand gently stroked Qu Yuanli, with a look of love, and his whole body couldn't help but tremble with excitement, this is simply a priceless treasure.

If ordinary people dedicate it to the emperor, they can also exchange it for the title of a county.

"Your Highness, does this plow have a name, and who made it?" A look of surprise and trepidation looked at Princess Qinghe.

"Yes......"

"My sister and I researched it a few days ago." The little son directly took out the drawings and handed them to Guo Huairen, "Uncle Guo, since it is useful, I will hand it over to your Ministry of Industry." Only you know how to use resources efficiently. ”

Princess Qinghe still wanted to speak, but was stopped by the little fat girl.

Little chubby's words, Guo Huairen definitely doesn't believe it, among all the children of Lao Li, the most talented is the little son of Princess Jinyang......

It's not that Guo Huairen looks down on anyone, looking at Datang, he is the authority.

Guo Huairen saw that the little fat girl didn't want to say, so he didn't ask in a hurry, but sighed, "Son, uncle, I still can't find a solution to one thing, and I hope that my son will teach uncle." ”

"Uncle Guo, you say." The little chubby girl patted her chest.
