"If Brother Chumo does this, your old man is afraid that he will hang you on a tree and smoke it."

"After the draw, I'm another hero."

Li Zheng persuaded: "There are still some temples not far from Chang'an. If Brother Chumo wants to do it, I can report to Dali Temple first. If Brother Chumo feels that he is not happy, he can kill a few monks and get punished appropriately. Wouldn't it beauties?"

"You support me, right?"

"No, Brother Chumo can't hear me being slanderous?"

"Can you still say the opposite?"

Sometimes it’s so embarrassing to communicate with people.

Sometimes you can reason with him, obviously it is useless.

If you want to talk about philosophy to him, you will easily suffocate in philosophy.

Let me talk to him about health and talk to the ancients about trace elements and dietary balance. It seems that it is not as effective as possible and it is easy to bleed.

Youdao is worse than dying in silence than silence.

In short, it is useless to say more.

Li Zheng smiled awkwardly and asked again: "Chumo, do you know many generals in the court?"

"That's natural." Cheng Chumo nodded and said.

"How much do you know?" Li Zheng asked again.

"It's okay, no one in the Cheng family knows the generals with good looks in the army."

Li Zheng continued, "Where is the border army?"

"Border Army?" Cheng Chu meditated for a while and said, "What are your ideas for fighting the border army?"

"If I don't do anything, I have a business that needs your help, so of course I have to hide it from some people and officials."

"If you have any questions, I will definitely help you if I can help you."

Li Zheng shook the goose feather fan in his hand and poured a cup of tea for Cheng Chumo, "Don't worry, Brother Chumo can drink a bowl of water first."

Focusing on what was in Li Zheng’s room, Cheng Chumo asked in confusion: “What are you drawing a carriage? Where are the horses?”

"Is this a car that doesn't require a horse?"

Cheng Chumo looked at it for a long time and said, "Is this a ox cart?"

"What does your ox cart look like?"

Cheng Chumo looked at the painting Li Zheng painted on the wooden board, "What is this?"

"A tool to improve transportation, with it alone, you can pull the goods."

"Is that true?" Cheng Chumo looked suspicious, "Even if there are no animals, I can pull the goods alone."

People are indeed incomparable, just like Cheng Chumo breaks chopsticks, for him, there seems to be no big difference between a chopstick and a chopstick.

After appreciating the drawing, Cheng Chumo said, "It's so annoying when he grows three wheels."

"Brother Chumo, three wheels are the essence." Li Zheng smiled.

Cheng Chumo thought, "Is that right?"

Li Zheng patted Cheng Chumo's shoulder, "You are not aware of your studies."

Because the people of Chang'an are sinister, Cheng Chumo has not wanted to go to Chang'an for the past two days.

He decided to stay for dinner in the evening. Li Daxiong cooked in person in the evening. Looking at the somewhat charred food, Li Zheng felt a little moved from the bottom of his heart.

It was really not easy to grow up so big. When Li Zheng returned to the kitchen, he made a pot of eggs and fried millet, and then he barely passed by a meal.

After the meal, Li Daxiong shaved his teeth and said, "You kid didn't even know how to give birth to a fire when you were a kid."

Li Zheng nodded awkwardly, "It's all learned from books."

Li Daxiong sighed, "Reading is good, you can learn anything."

Cheng Chumo fell asleep after eating the meal, and a large pot of fried rice with eggs was basically eaten by this guy.

The millet rice is softer, and the fried egg fried rice is softer.

Of course, fried rice without sausage and chopped green onion is soulless.

He came to the academy with the drawings. Li Chunfeng said to Li Zheng: "Yan Liben was called back by His Majesty. I don't know what to do, but said he would come back in a few days."

Yan Liben was originally Li Shimin's subject, and it was reasonable to send his subject, Li Shimin, paper and scatter it away.

Should Yan Liben resign?

With Chu Suiliang and Li Chunfeng already, if Yan Liben resigns from his post or something, he will have to consider whether Li Shimin will be anxious.

Li Chunfeng is now full of energy with a book of mathematics in his hand, as if he has walked out of the bottleneck of the realm, and his spirit is raised.

Li Zheng smiled and said, "I think Master Li Chunfeng's realm has improved again, congratulations."

"I met you, Li Zheng, and I realized what it means to be someone outside of you." Li Chunfeng bowed and said, "If you want to talk about the state of mind, I am not as good as you."

"Master Li Chunfeng is too famous. His math is profound and profound. What I learned below is nothing more than a small path." Li Zheng remembered some Olympiad questions and some classic questions in later generations. I am afraid that Li Chunfeng would go crazy when he saw those questions.

After hearing Li Zheng say it, Li Chunfeng sighed again, "It's okay here. I remember that those scholars didn't say anything in Hongwenguan, but they still had no interest in numbering in numbers, and even said that numbering is useless. They are more willing to read those poems, books, etiquette, and spring and autumn."

Li Zheng was displeased when he heard this, "Who said that math is useless? Mathematics is always inseparable from life."

Li Chunfeng nodded slightly, "It's hard to describe it, it's not that mathematical techniques are not that useful to them, and have nothing to do with governing the country and ensuring the people."

"Farting, do they know how much food is in the Central Plains in a year to make people in the Central Plains full? Do they know how big the area of ​​the Central Plains is? Do they know big data?"

Li Chunfeng looked puzzled, "I know the area, but I don't know what big data the county marquis is talking about?"

"Big data..." Li Zheng kept silent.

"What is big data?" Li Chunfeng asked again.

"How do you explain this..."

Li Zheng took two steps back and forth to take Li Chunfeng to the class.

Under the surprised gaze of Chu Suiliang and Shangguan Yi, who were eating hot pot and sweet potatoes, Li Zheng began to write with charcoal on the wooden board on the wall.

"There are many things in this world that are causal and effect. In the form of mathematical techniques, once some errors occur in the condition, the results will change greatly." Li Zheng said while writing on the wooden board.

"When there is a certain change in the total population, total labor force, and total per capita wealth, there will be certain changes in the future national policies."

After hearing Li Zheng's words, Li Chunfeng heard some clues, "Are you all the conditions?"

"Yes, it's all conditions." Li Zheng wrote again, "There is still productivity that has reached a certain bottleneck or the tax and transaction volume generated, which has stabilized and not increased. If it continues like this, it will form..."

"If you become a stagnant water, if you don't open source, you will continue to stagnate." Li Chunfeng quickly came to the conclusion.
