"If Brother Chu Mo does this, I'm afraid your old man won't want to hang you on a tree and smoke it."

"After smoking, so-and-so is another good man."

Li Zheng persuaded and said: "There are still some temples not far from Chang'an that have survived, if Brother Chu Mo wants to do it, he can report to Dali Temple first, if Brother Chu Mo feels that he is not happy, he can cripple a few monks and increase the punishment appropriately, isn't it beautiful?" ”

"You're in favor of doing that, aren't you?"

"No, can't Brother Chu Mo hear that I'm talking back?"

"Can you still say the other way around?"

Sometimes it's just so awkward to communicate with people.

Sometimes you can reason with him, obviously it doesn't work.

If you want to talk to him about philosophy, it's easy to suffocate in philosophy.

Let's talk to him about good health, and talk to the ancients about trace elements and dietary balance, it seems that it is not the best and it is easy to get rid of it.

There is a Tao that erupts in silence and is better than dying in silence.

In short, much is not helpful.

Li Zheng smiled awkwardly and asked, "Chu Mo, do you know a lot of generals in the court?" ”

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

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

"It's okay, there are faceless generals in the army, I don't know any of the Cheng family."

Li Zheng continued: "What about the border army? ”

"Frontier Army?" Cheng Chu pondered for a while and said, "What are you doing with the idea of fighting the border army?" ”

"Don't do anything, I have a business that I need your help with, of course, I have to hide it from some people and officials."

"If there is anything, just say it, my Cheng family will definitely help you if they can help."

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 the things in Li Zheng's house, Cheng Chumo asked suspiciously, "Are you painting a carriage?" What about horses? ”

"It's a cart that doesn't need horses?"

Cheng Chumo looked at it for a long time and said, "This is an ox cart? ”

"What does your ox cart look like this?"

Cheng Chumo looked at Li Zheng's painting on the wooden board, "What the hell is this?" ”

"A tool to improve transportation, with which one person can pull goods."

"Really?" Cheng Chumo looked skeptical, "Even if there is no livestock, I can pull the goods alone." ”

People really can't be compared, just like Cheng Chumo broke chopsticks, for him, there doesn't seem to be much difference between a chopstick and a pair of chopsticks.

Cheng Chumo admired the drawing and said: "There are also three wheels, which are strange to the eyes." ”

"Brother Chu Mo, the three wheels are the essence." Li Zheng said with a smile.

Cheng Chu was silent, "Really? ”

Li Zheng patted Cheng Chumo's shoulder, "You don't read much, I don't blame you." ”

Due to the sinister hearts of Chang'an, Cheng Chumo didn't want to go to Chang'an for the past two days.

decided to stay and eat at night, Li Daxiong personally cooked in the evening, looking at the somewhat charred food, Li Zheng felt some emotion in his heart.

It's not easy to grow so big, and when I returned to the kitchen, Li Zheng made a pot of egg scrambled millet rice, and the meal barely passed.

After the meal, Li Daxiong shaved his teeth and said, "You kid didn't even know how to make fire when he was a child. ”

Li Zheng nodded awkwardly, "I learned it from books." ”

Li Daxiong let out a long sigh, "Reading is good, you can learn anything." ”

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

Millet rice is softer, and scrambled egg fried rice is softer.

Of course, egg fried rice without sausages and chopped green onions is soulless.

Carrying the drawings to the academy, Li Chunfeng said to Li Zheng: "Yan Liben was recalled by His Majesty, I don't know what to do, I said that I would come back in a few days." ”

Yan Liben was originally Li Shimin's courtier, and it was reasonable for his courtiers to send Li Shimin's paper back and forth.

Do you want Yan Liben to resign?

There are already Chu Suiliang and Li Chunfeng, and if Yan Liben resigns or something, he has to take into account whether Li Shimin will be anxious.

Li Chunfeng took a book of mathematics in his hand, and now the whole person is full of energy, as if he has stepped out of the bottleneck of the realm, and the spirit of the whole person has been raised.

Li Zheng smiled and said: "Come to think of it, Li Chunfeng's realm has improved again, congratulations." ”

"After getting acquainted with you Li Zheng, Poor Dao knows what it means to have someone outside the world." Li Chunfeng said: "If you want to talk about the realm, the poor road is not as good as you. ”

"Li Chunfeng has a long reputation, and his mathematics is broad and profound, and what he has learned is just a small way." Li Zheng thought of some Olympiad topics in later generations, as well as some classic titles, and was afraid that Li Chunfeng would go crazy when he saw those questions.

After listening to Li Zheng, Li Chunfeng sighed again, "It's okay here, I think that when I was in Hongwen Hall, those scholars didn't say anything on the surface, but they still had no interest in mathematics in their eyes, and even said that mathematics was useless, they were more willing to read those poems, books, rituals, spring and autumn." ”

Hearing this, Li Zheng was not happy, "Who said that mathematics is useless, and mathematics is inseparable from all times in life." ”

Li Chunfeng nodded slightly, "It's hard to say, it's not that math is not so useful to them, and it has nothing to do with governing the country and reassuring the people." ”

"Fart, do they know how much grain in the Central Plains is enough for the people of the Central Plains to eat in a year? Do they know how big the Central Plains is? Do they know about big data? ”

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

"Big data ......" Li Zhengsan kept silent.

"What is Big Data?" Li Chunfeng asked again.

"How do you explain this......

Li Zheng took two steps back and forth and walked to the classroom with Li Chunfeng.

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 have a causal relationship, and in the way of mathematics, once the conditions have some errors, its results will also change greatly." Li Zheng said as he wrote on the wooden board.

"When there are certain changes in the total population, the total labor force, and the total per capita wealth, there will be certain changes in the national policy in the future."

After listening to Li Zheng, Li Chunfeng heard some clues, "These are the conditions you said?" ”

"Yes, it's all conditions." Li Zheng wrote again, "There are still productive forces that have reached a certain bottleneck or the tax revenue and transaction volume generated have tended to be stable and have not risen, and if they continue like this, they will form a ......."

"It has become a stagnant water, and if it has not been opened, tax revenue will have stagnated." Li Chunfeng quickly came to a conclusion.

Li Zheng said again: "We can deduce the law of the outbreak of wars and the prosperity of dynasties from the total population, total labor force, and per capita wealth of all dynasties. ”
