Li Er came, and he also brought Concubine Yang and Wu Meiniang, followed by the eldest grandson Wuji, and he didn't know that he thought he was really here to visit relatives.

"Meet Your Majesty, meet Niangniang!" Cheng Cuishi, who had just picked up a piece of mutton from the pot, couldn't help but be stunned, and quickly got up and said to greet him.

Cheng Chubi hurriedly picked up the chopsticks, brushed a few pieces of meat and ate them, if he doesn't eat them now, he won't have time to eat them later.

"There's no need to be polite, today is a family dinner, so there's no need to be polite." Li Shimin laughed, then sat down, brushed a piece of mutton into the pot, picked it up and ate it, and after a few seconds, he said happily: "What is this?" So delicious? ”

This guy really doesn't think of himself as an outsider!

However, the eldest grandson Wuji watched from the side, and couldn't help but feel a little jealous in his heart, what is this? This is grace, this is trust! In the past, this kind of trust was only in the eldest grandson's family and a few other families, but now it's the turn of the Cheng family, and the Cheng family can't do it if it's not prosperous.

Cheng Yanjin watched from the side, it was really proud. See? The saints are not worried about eating poison in my house, this is trust!

"It's called hot pot." Cheng Chubi said.

"Hot pot? It's a good thing, just eat a few pieces, and the body is warm, it's a good thing to ward off the cold. Li Shimin smiled slightly, but the speed in his hand was not slow, and after eating some mutton, he asked: "Can you eat this thing?" ”

"It's better to eat less spicy, you can use clear soup, white bone stewed chicken as raw materials, and then put some heat-clearing and detoxifying ingredients." Cheng Chubi said.

"Good, good, so, very good, so good. If it is the cold season, every household can eat this kind of food, then there will be no one starving to death in Datang. Li Shimin couldn't help but sigh and said. However, he quickly shook his head again, how could this thing be affordable for every family?

It's made of pure copper, that's a lot of money, and it is estimated that only someone like Cheng Chubi would do such a thing.

"Your Majesty, in fact, it is not difficult to use it in every household." Cheng Chubi smiled slightly and said: "This thing can be made of pottery, just like making a clay pot for cooking, and the people can still make hot pot if they catch a few fish in the river." ”

"In this way, this manufacturing method will be passed on, hahaha......" Li Shimin laughed, Cheng Chubi shook his head secretly, the idea is good, and the reality is very backbone.

"Father-in-law, you come to eat, this thing is really delicious." Cheng Chubi didn't bother to pay attention to Li Er, but instead beckoned the eldest grandson to forget, how to say that this old yin man is also one of his fathers-in-law.

Since Cheng Chubi called Chai Shao his father-in-law Taishan, this title has gradually spread among the nobles.

"Very good, very good." The eldest grandson Wuji nodded with satisfaction, it seems that you are still a little filial.

"Whether a man's kidneys are good or not, only her woman knows." Cheng Chubi couldn't help muttering.

"San Lang, although this thing is good, but don't indulge too much in these strange tricks, since you are a Confucian student, you should read more books, you should ......" Li Shimin lectured while eating.

"Your Majesty, the hot pot is so delicious, I don't know when the cow in Huangzhuang will break its leg." Seeing that the mutton was about to be eaten by Li Er, Cheng Chubi said with some pain.

"You erect! Cattle is the most important weapon of the country, in some places a village of people have a cow, you are good, you want to eat beef every day! ”

"The beef is delicious, since the Tang Dynasty is so short of cattle, why not ask the Western Turks and the Tuhun Valley, Murwei, Khitan and other ethnic groups? There are quite a lot of cattle and horses. Cheng Chubi said.

"You don't know that these cattle are just like those beards, unruly, and they can't become ploughing cattle at all." The eldest grandson Wuji said, this guy was originally from the Xianbei clan, but he kept saying that others were Hu'er, and Cheng Chubi also obeyed him.

Cheng Chubi smiled proudly and said, "Ha! There is no cow in this world that cannot become a ploughing ox, as long as you use the right method, even a tiger can become a ploughing ox. ”

"Really?"

Everyone couldn't help but look at Cheng Chubi, being looked at by so many people, Cheng Chubi suddenly felt a little speechless, do you need to be so surprised?

Cheng Chubi didn't know, Datang lacked ploughing cattle, very short, many households' fields were grassy, and there was no way to cultivate, many times it was the father's son pulling the plow in front, and the old lady supporting the plow behind him. Whoever can afford to raise cattle is definitely a big family in the countryside.

Cattle are more expensive than human life!

"Ah...... Yes...... Yes...... Did I speak just now? I don't seem to be talking, am I? "Cheng Chubi is also depressed, is it really that I said it wrong?

"Shaft!" Li Shimin glared at Cheng Chubi fiercely, and then put down the chopsticks, and Cheng Chubi hurriedly took the opportunity to eat a few more bites.

"Don't hurry to the study!" Cheng Yanjin kicked him and glared at him and said.

"Grandpa, I haven't eaten yet!"

"Where is all this nonsense? Hurry to the study! ”

“……”

Cheng Chubi was very depressed, he had already known that Li Erlai definitely had something, this old man had always been on the Three Treasures Hall for nothing.

I had no choice but to follow to the study.

When he came to the study, Li Er sat in the first place, Cheng Yanjin and the eldest grandson Wuji sat next to him, Cheng Chubi was helpless, so he had to stand, just like a trained child.

Li Er looked at Cheng Chubi and asked, "Can you say it now?" ”

"What's in it for you?"

"If this is done, you will see cattle with broken legs every day." Li Shimin glared at Cheng Chubi fiercely and said, "If you can't do this, you won't want to eat beef in your life!" ”

"Actually, it's very easy to do this, open up the cartilage of the cow's nostrils, and then tie it with a rope, or lock it with a ring made of iron and copper, and tie the rope, don't talk about the cow when the time comes, even the bull demon king has to be obedient."

"What is the Bull Demon King?"

"It doesn't matter, as long as it is equipped with a paddy field plow, a cow can easily cultivate dozens of acres of land in a day."

"What is this paddy field plow?"

"The paddy plow is a kind of thing like a curved plow?"

"What is the Quyuan plow?"

"Princess Wen Changcheng didn't tell you?"

"Wen Cheng knows?"

"Yes, she made it up." Cheng Chubi couldn't help but speak, his eyes were red and his heart was not beating.

"Go and call Wen Cheng in." Li Shimin's brows couldn't help frowning slightly, Li Zhong answered, and then walked out, and a few minutes later, the unknown Princess Wen Changcheng walked in.

Until now, she still has a puzzled face, what the hell is going on? At this time, Concubine Yang and others had already chatted with Cheng Cuishi about the birth death record of the Chang'an woman.

In fact, Cheng Chubi couldn't make up his mind, he didn't know if the paddy field plow could be used, so he simply pulled Li Shu into the water, Li Shimin loved Li Shu so much, presumably even if he made a mistake, it would be fine, right?

Cheng Chubi didn't remember the Quyuan plow, but he knew the paddy field plow, and he saw it when he went to the village when he was a child, but it seemed to be used to plow the paddy field.

"Your Majesty, I'd better draw it first." Cheng Chubi smiled slightly, and didn't wait for Li Shimin to reply, and quickly took out a blank piece of paper to talk to himself.

The paddy plow is very easy to draw, and you can draw something with a few strokes.

Everyone's support, a lot of support~~
