At dusk, the clouds on the horizon are gradually covered by night.

In the prince's bedroom, there were whips broken in two on the ground.

After breaking the two whips, Emperor Hongzhi also ended his good education of Zhu Houzhao, and sat on the chair sweating profusely, while Zhu Houzhao knelt on the ground, grinning and snorting.

The pain is really painful, but Zhu Houzhao has been stubborn since he was a child, and he has been pumped a lot, and over time, there is a layer of old skin on his buttocks, and the pain dissipates after a while.

Emperor Hongzhi wiped the sweat from his forehead, his whole body was comfortable, and pumping his son was a physical task, which was also one of the few ways he could exercise his body.

On weekdays, sitting on the dragon chair for a long time, even the emperor suffers.

It's okay to smoke the prince, it's still good.

"Prince, I ask you if you know if you are wrong!"

If it was normal, Zhu Houzhao would really admit his mistake obediently, but this time, he thought that he hadn't made any other mistakes except for stealing a cabbage from Du Shen, not to mention that Liu Jin couldn't betray him, who could say that he was wrong?

So, he decided to resist strictness.

"Back to my father, my sons don't know."

Zhu Houzhao raised his head, his face was full of stubbornness, this meal could not be in vain.

The naïve Zhu Houzhao didn't know that the reason why Emperor Hongzhi smoked him was not because of planting cabbage, but because he had to spend money to tear down the floor and turn back, so he was distressed before he moved.

Emperor Hongzhi sneered at Zhu Houzhao, if it weren't for the sourness of his hands, he would rush this sentence, and it would be another slap.

"It's almost winter, and you told me that you want to grow cabbage, isn't that wrong?"

Xue Li and the other eunuchs were still there, but he didn't say the real reason to his face, otherwise what would others think of him, who should be the emperor?

Zhu Houzhao couldn't accept this reason, and said angrily: "Father is pedantic, why can't you grow cabbage in winter, I don't believe you can go into the shed yourself to see if your son's cabbage grows well." ”

This time, he learned to be obedient and didn't dare to call himself a faint king.

Emperor Hongzhi glared at him and said, "Nonsense, I am the king of a country, how can I be as disgraced as you." ”

Zhu Houzhao was extremely angry and argued: "My father is pedantic, and my son will let you see it!" ”

As he spoke, Zhu Houzhao gritted his teeth and directly demolished the shed.

Emperor Hongji's eyes widened.

After the shed was dismantled, I saw that on the ground in the middle, a green cabbage was just growing, bright and dripping, the cabbage was not big, and it looked like it had just sprouted not long ago.

But this season, shouldn't all the cabbage have been picked and stored?

Why is this cabbage different?

The batch of cabbage planted by Du Shen has only been a month since it is full, which is of course different from the cabbage planted normally.

Emperor Hongji was curious, he stood up and leaned closer, taking a closer look.

A moment later.

He frowned, "I want to know what the hell is going on. ”

Zhu Houzhao was straightforward, and told all the things about the vegetable greenhouse and cabbage with a cold face, and as for the process of getting the fruits of labor, he vaguely mentioned it.

After listening to this, Emperor Hongzhi thought about it, if according to Du Shen, the vegetable greenhouse can grow vegetables and even wheat in winter, wouldn't it be three seasons a year?

Since ancient times, the country has been people-oriented, and the people have taken food as the sky.

The common people live a life facing the loess with their backs to the sky, and the livelihood is to farm the land, if this thing can be promoted, isn't it a good plan for the people!!

Thinking of this, Emperor Hongzhi couldn't sit still, he had to meet Du Shen, otherwise it would be difficult to settle in his heart.

Xue Li reminded: "Your Majesty, there is a curfew now, if you want to leave the palace, you have to wait until at least tomorrow, besides, it is not appropriate to have too many private visits......

Emperor Hongzhi calmed down: "That's the case, then I'll make plans tomorrow." ”

As he spoke, he looked at Zhu Houzhao again, feeling a little guilty in his heart, this time it seemed that he had indeed been wronged.

However, Emperor Hongzhi thought for a moment, and his face became gloomy again.

Since Du Shen attaches so much importance to the vegetable greenhouse, where did the prince's cabbage come from?

He didn't even have to think about it to know that the means he got must not be bright!

"That's it! I'm tired today, so I'll write it down for the time being, and I'll look for a chance to clean you up when I get back! ”

Emperor Hongzhi had a black face and waved away.

Zhu Houzhao was stunned, what happened just now?

He doesn't seem to have done anything, why did he go back and clean himself up again?

Just when he was confused and complaining, suddenly, Xue Li walked in again.

"Prince, Your Majesty asked the slave maid to take this cabbage away, saying that it was not safe to stay with you, and it was going to be planted in the imperial garden."

As he spoke, Xue Li stretched out his hands in Zhu Houzhao's grief-stricken gaze, and with a pop, pulled out the green cabbage with soil.

"This is the fruit of Prince Ben's labor!"

Zhu Houzhao shouted in humiliation, tears hidden in his eyes.

I finally got a cabbage and planned to plant it, but who had ever been beaten for no reason, just beat it! Before leaving, he also gave his cabbage away.

Who is the thief?

……

Noon the next day!

Du Shen taught Zhang Hao and others mathematics in the academy, and he took physical education classes for several days in a row, and he was a little overwhelmed.

"Mathematics is often used in life, as a reader, mathematics must be learned well, for the teacher a few days ago taught you to memorize the multiplication formulas?"

Du Shen held the chalk in one hand and pressed the other to the table on the podium.

Although the academy has not yet been fully completed, the classrooms are almost finished.

Out of professional habits, Du Shen put a table on the podium, while Zhang Hao and the others had a desk for each person, if they were not wearing ancient clothes, they were not much different from the students he had brought before.

Zhang Hao replied: "If you go back to your master, the apprentice has already memorized it backwards. ”

Zhao Xiu and others, even with the youngest baby, followed: "It's all memorized." ”

Du Shen nodded his head and smiled with satisfaction: "Not bad, since you have memorized everything, I will teach you how to use vertical calculation to add, subtract, multiply and divide today." ”

As he spoke, Du Shen wrote two lines of numbers on the blackboard, then drew a horizontal line underneath, marking a multiplication on the left.

Arabic numerals were directly borrowed by Du Shen, and they were named without discipline: Daming numerals.

After all, the time and circumstances are different, and if you really want to call them Arabic numerals, you have to explain where Arabic is and how he knows Arabic numerals, so he simply blacks them out.

Then, Du Shen calculated in front of them, and explained the principle of multiplying each other to get two sets of numbers, and carry them to get the answer.

Zhang Hao and the others shook their heads when they heard this, they had accepted the number of 1 to 10 instead of Chinese characters, and now after seeing the method of vertical calculation, they suddenly felt that a door had opened in their heads.

The convenience of numbers and the advancement of calculation methods are leading in this era, and they are much more advanced than methods such as digital chips.

After Du Shen finished speaking, he listed a few questions for Zhang Hao and others to practice, and he wiped his hands.

wiped their hands clean, Zhang Hao and others also solved all the questions, of course, there must be right and wrong.

Du Shen shook his head, and was about to talk about the mistakes they made in doing the question, but coldly, he glanced at it, and saw a middle-aged man wearing coarse cloth clothes, but extremely clean, standing at the door of the classroom, as if he had been listening to the class for a long time.
