May of the seventh year of Zhenguan.

Datang is basically nothing serious.

But actually......

It's also better that nothing is too big.

"What is the colt doing?"

Lee fiddles with a piston-linkage model of a steam locomotive made of paper.

The good news is that he finally remembered all about this model.

"Come here."

Li Chong then motioned for Li Lizhi to come over and sit on his lap.

"I'm working on a steam locomotive."

Li Lizhen may have felt a little shy at first, but now it's been three months.

She's not shy anymore.

And......

She loved the feeling of being held by Li Chong, or sitting in his arms.

"You see, from here, the steam comes in, and the piston pushes the piston, and the piston moves with the linkage, and the connecting rod moves with the wheels."

"I don't understand."

Li Lizhi hid in his arms and was coquettish directly.

Li Zhong looked at her in his arms, with a smile on his face, and then kissed him directly, but he only touched it lightly, and it was not right, and then he was quickly blocked by the other party.

"Someone is watching!"

"It's all my own."

Due to today's rest.

Li Chong also suddenly remembered and said, "Speaking of which...... I haven't checked my body for a long time, do you want to see Dr. Sun. By the way, enter the palace and show it to your mother. ”

has been in Datang for so many years, to be honest, he almost forgot when Empress Changsun died of illness.

But one thing is for sure, Li Yuan is not dead, and the eldest grandson empress is not yet there.

Li Lizhen had doubts at this time, and asked:

"Speaking of which...... Why do you see your queen mother so often? ”

Li Zhong frowned, "Often? Do I have one? ”

"Yes, and it's that Sun Simiao every time."

Li Chong said: "That's not because your mother is weak and sick. This summer has taken care of the body, and it is not easy to get sick when autumn comes. ”

Li Chong saw that she didn't want to move, so he asked people to find Sun Simiao first. In case Sun Simiao is not here today, go out to see a doctor, or collect medicine, then the two of them will have to run for nothing. And after thinking about it, let's set a day off.

Followed by......

The two of them made all kinds of small movements.

Afternoon.

Li Chong also asked people to boil warm water and wash her hair personally.

Because in the morning, he had scattered her hair and messed it up.

The slaves and maids of the princess's mansion all watched the movements of the two.

Let's be honest.

They have never seen such a gentle, and crucially, such good-looking man.

With the princess, it is simply a love match, like glue.

The day runs from morning to noon and then to afternoon.

They didn't seem to have seen the princess for a moment, not with a smile on her face.

Seeing that the slaves and maids were all inexplicably in a good mood.

Even so, it doesn't seem like it's their business.

Afternoon.

The two also looked at the property of the current princess's mansion together.

With so much money, it's a pity not to use it for financial management.

It's just a pity that officials can't take the lead in doing business.

Otherwise, Li Chong should already be a billionaire by now.

In the evening.

Both of them took off their coats, leaving only a thin pajamas, and they naturally slept together, not too hot.

……

Following.

Li Chong arrived at the Academy of Sciences early in the morning.

Then he told everyone about his latest model.

"Dean, I have a question!"

"Say."

"What is the purpose of this rod?"

Li Chong said: "The function of this rod is to control the work done and maximize the efficiency of the cylinder. ”

Under Li Chong's explanation, everyone couldn't help but nod.

I didn't expect that just such a small change could more than double the efficiency.

So......

(This chapter is not finished!) )

Chapter Ninety-Five: Daily

Science is such an amazing thing.

"How's the steam mill you have refitted?"

Then they took Lee to the converted steam mill.

Since the cylinders were rough at the beginning, the horsepower was very small.

Naturally, I don't know if the money from the coal burned can be earned back by grinding wheat.

But Li looked at it again and did a good job.

At the very least, this proves that it can be used.

Of course!

This is at most a toy, and in order to really apply it, it must at least increase this efficiency by ten times, or even twenty times.

Let them all think twice about how to improve efficiency.

After instructing what to do, Li Chong came to Guozijian again.

But he doesn't have to go to class, he just walks around.

Anyway......

If a student has any questions, they can ask them directly.

He will answer on the spot.

If there is no problem, then let the assistant teacher of Guozi take them to learn.

Like what vertical calculations, these most basic, they have to lay a good foundation.

But seriously.

Almost all of the people who come here to study are in their teens, almost twenty years old.

Such a simple question should not be like an elementary school student, studying for an entire semester.

Li Zhong felt that in two weeks at most, he should be able to fully grasp it.

The rest of the time is for homework and exams.

Be sure to do it, and everyone can get 100 points.

It may not be a big problem to miscalculate in later generations, but if you miscalculate in Datang......

Then I guess I'll have to lose my head.

Guozijian's Guozi sacrificial wine also invited Li Chong to sit down and talk about arithmetic.

"Now that the arithmetic reform is being carried out, I am afraid that it will be difficult to come up with questions in the future. The imperial examination for the coming year is clearly counted as one subject, what is the captain of the horse going to do? ”

Li Chong only noticed the situation in Chang'an City, but he didn't notice that there would be candidates from other states in the annual clear calculation exam.

After thinking about it, he said: "Actually, it's not a big problem, anyway, the question still refers to previous years, like in previous years, and there are no restrictions on the calculation method, as long as you can answer it correctly." Of course, I still hope to see the students of Guozijian list the whole process of doing the questions. After all, if something is wrong there, at least the reason can be found. ”

Guozi sacrificed wine and said: "Then maybe next year's topic, you have to ask the horse captain to come up with the question." ”

"Ahem! In fact, other people do the same. I can do an audit. ”

Li Chongcai should not be a fool, this is his own question, how troublesome it is!

If you take the task on yourself, you must not die of exhaustion.

He thought that in two years, he would directly resign from this official position and let the assistant teacher come up.

He didn't think the teaching assistant had a bad grasp at all.

Of course!

Maybe the teaching assistant is a teaching assistant after all, just like a concubine is a concubine after all, it is difficult to straighten it out, then find other teachers, and there are not no other teachers in the country.

Anyway......

The teaching materials are already available, and even if Li Chonglai is asked to teach them, at most they will be taught like that. In fact, the difference won't be huge.

Guozi Sacrificial Wine knew that Li Chong was unwilling, so he didn't force it next.

It's just that if Li Chong has time, he can come to Guozijian more often.

I don't know why, Li Chong suddenly had a hunch that the number of applicants for next year's Ming Arithmetic Department may be more than in previous years.

Of course!

Since the Ming Arithmetic Department is generally not too high, this kind of many, it will not be particularly much.

When the time comes......

If everyone's answer is good, then how to choose?

See whose handwriting is good?
