Lu Yuan looked at the window with the gauze curtain and said:

"Why don't you go back? What are you waiting for me to do?"

There was a soft hum from inside the carriage, and Gu Qingwan said softly:

"I'll go home with you~ Anyway, I won't be able to eat if I go back early.

Who dares to use chopsticks in this house without waiting for you, the boss, to come to the table~"

Lu Yuan chuckled after listening to Gu Qingwan's words.

That's~

Outside, Gu Qingwan is the emperor, but at home, she is the boss~

…

The second day.

Lu Yuan went to Qingbei University at 8:30.

I am currently practicing immortality at night, so I am not sleepy at all.

To meditate this evening is equivalent to resting.

This makes me feel more energetic than having slept all night.

After Lu Yuan arrived at Qingbei University.

The students here have already been prepared.

Lu Yuan took a look and said, "Hey, my goodness, how many people are here?"

Looking over it, there must be at least close to a thousand people!

Are all the people from the Imperial College here?

Um……

Probably, because people from the Imperial College are easy to find, and these people sit on the floor.

As for the students at Qingbei University, they all have tables and stools.

After Lu Yuan came, I didn't know who was responsible.

When Lu Yuan walked towards the high platform, the students from Qingbei University stood up and shouted loudly:

"Good morning, principal."

The students of Qingbei University truly admire Lu Yuan.

Among the students, there are young people in their twenties and middle-aged people in their thirties.

But no matter who it is, everyone respects Lu Yuan, who is only twenty-two years old.

In just half a year, so many great inventions have come out.

The steam engines and trains are beyond the times!

Moreover, the principal of my family is simply the most versatile of all, not only in industry.

The potato production has doubled.

Directly solved the problem of reduced grain production due to winter floods in the south.

There are also mortars used to suppress bandits in the south, and the latest invention some time ago, the ore refiner.

Each of these items makes everyone admire them.

Therefore, no one will care about Lu Yuan's age. Now Lu Yuan is an elder, senior, and master in everyone's eyes.

Lu Yuan was stunned for a moment when these people all called him principal.

However, after coming back to his senses, Lu Yuan grinned and said:

"Sit down."

Later, Lu Yuan came to the podium, sat down, and said:

"Has yesterday's problem finally come to an end?"

The two student representatives who were selected by Lu Yuan yesterday stood up and nodded, and then talked about yesterday's problems.

Lu Yuan was holding a large enamel vat, leaning on a chair with his legs crossed, drinking tea while answering the students' questions.

He looks like a veteran cadre.

After spending more than half an hour answering all the questions, it was already ten o'clock.

Hurry up and give lectures, there are still two hours until 12 noon.

Afterwards, Lu Yuan stood up, looked at the students at Qingbei University below, and said directly:

"I gave you an assignment yesterday. Do you have the answer?"

Next, many people expressed their conjectures.

But the answer is obvious...

None of them are right.

That’s normal, after all, it’s just the beginning.

Moreover, these people have not learned this thing. Lu Yuan immediately smiled and said:

"Today we continue to learn about temperature, and the formation of holes in frozen tofu is also very simple.

First of all, water has a strange characteristic. At four degrees, it has the highest density and the smallest volume.

After reaching zero degrees, the volume of water begins to increase, reaching 10% greater than at normal temperature.

So, what happens after the tofu is frozen..."

What follows is a two-hour lecture.

Lu Yuan now prepares lessons when he comes home at night, so Lu Yuan has planned everything from where to talk about it.

So there will be no lag, and there will always be lots and lots of things to talk about.

One thing after another.

Everyone was very excited after hearing this.

Especially for the students of the Imperial College, this is even more true!

After all, for the students of the Imperial College, this kind of teaching method has never been seen before.

And these things Lu Yuan mentioned are things that students at the Imperial College have never been exposed to.

After all, if you can enter the Imperial College at around thirty years old.

Before this life, I must have read the books of saints and sages every day, and I didn’t understand anything about life.

Therefore, these things Lu Yuan mentioned are for people in the Imperial College.

This is really strange.

At 12 noon, the morning class is over.

Everyone goes to the canteen to eat first.

Qingbei University, as a key support object of the imperial court, is really changing with each passing day.

This was a simple canteen at Qingbei University. There were no tables, chairs or benches in it. When everyone went to eat or something, they had to go in and eat while squatting or standing up.

It's almost finished decorating today.

All the students from Qingbei University went to have dinner. Lu Yuan also took a meal and went to a small house. Today, Gu Qingwan also came.

As for the students of the Imperial College.

Then of course I would go back to the Imperial College to eat.

Or go eat on the street.

After all, we don't care about these people's food here.

It's okay to come to attend classes, but not to come to have a meal.

…

"Hey, the principal even personally prepares meals for the students~"

As soon as Lu Yuan entered the room with two bowls of food, Gu Qingwan immediately greeted him.

Listening to Gu Qingwan's joking, Lu Yuan did not respond, just raised his eyebrows and said:

"The funds approved by the Ministry of Rites are too small. Look, there is only one meat dish, and the rest are all vegetarian.

Our people here will be the pillars of the country from now on, how can we just eat this?"

After hearing what Lu Yuan said, Gu Qingwan quickly said:

"When I go back today, my sister will definitely give a good lesson to the people in the etiquette department!"
