Around five o'clock in the afternoon, Lu Yuan was almost hungry.

At this time, more than 500 people had gathered in the school grounds.

Except for the students of Qingbei University, the rest are all Guozijian people.

At this time, Lu Yuan stood in front of the loudspeaker and said:

"Alright, that's all for today's lesson, tomorrow morning...... Continue at nine o'clock, and before leaving, I will leave you a homework.

Everyone must have eaten this frozen tofu, so the question is, why is there a honeycomb-shaped hole in this winter after this tofu is frozen? ”

After that, Lu Yuan smiled and said:

"Everyone has to think for themselves, you can also discuss, tomorrow the person who answers correctly, at noon, the principal, I will take care of your meat!"

Listening to Lu Yuan's words, the people below also let out a burst of cheers.

And so concludes today's lesson.

After Lu Yuan stood on the high platform and waved his hand to the gang with a smile, he packed up his teaching materials and walked towards the house in the distance.

Lu Yuan knew that Gu Qingwan was here today.

At noon, the two of them were still eating together in that small room.

Now call Gu Qingwan, and the two of them will go home for dinner together.

When Lu Yuan pushed open the door and entered, he saw Gu Qingwan sitting behind the table by the window, looking at him with a smile.

Lu Yuan was not polite, and after approaching, he came directly to Gu Qingwan's side, picked up the teacup in Gu Qingwan's hand, and raised his head to drink.

This afternoon, it was really bad for Lu Yuan.

This voice is hoarse.

It was really the first time that Lu Yuan had said so many things in one afternoon.

The key is to say it out loud.

This is now said to Lu Yuan as if it was the first day of military training in school.

This throat is really hot.

Gu Qingwan watched Lu Yuan pick up his cup and drink it, and said coquettishly:

"This is my sister's cup~"

After Lu Yuan finished drinking, he continued to pour water from the teapot next to him, and raised his eyebrows and said:

"Why, I don't dislike you."

After Lu Yuan's words were finished, Gu Qingwan's eyebrows were slightly curved, and her beautiful eyes were full of smiles, but she still said in a coquettish voice:

"Sister dislikes you~"

After Lu Yuan went down with a cup of water again, he raised his eyebrows and said:

"It's too late to dislike it now, let's go, go home for dinner."

Listening to Lu Yuan's words, Gu Qingwan glanced at Lu Yuan coquettishly, then got up and obediently followed Lu Yuan out.

"Lu Yuan, how can you understand everything, you know everything~"

Following behind Lu Yuan, Gu Qingwan couldn't help but say.

Lu Yuan walked in front and shook his head proudly:

"Read books, read more books and you will know.

Didn't I say it before, there is Yan Ruyu in the book, and there is a golden house in the book. ”

And Gu Qingwan blinked and said:

"Is there a book about the kind of book you mentioned, how come my sister never knew.

And, even if there is such a book...... Isn't that just for you to see, and for others not to look at it?

Why hasn't my sister ever heard about these things before? ”

Well......

Lu Yuan was silent for a while, but he also had a statement, and even raised his eyebrows and said:

"Of course, it's not enough to just read books, that's still to practice, think more and do more, and add a smart brain~"

Looking at Lu Yuan's smug appearance, Gu Qingwan really liked it to death, and couldn't help laughing, and said extremely dotingly:

"Okay, good~~ You're the smartest~~"

Lu Yuan came to the place where he put his bicycle, and said:

"You're going to take my car back?"

Gu Qingwan looked at Lu Yuan's bicycle, to be honest, Gu Qingwan still wanted to do it.

Merely......

This place is too close to the palace, not to mention, the national eunuch is next to it.

The officials in this Guozijian are not low-level, and because of Gu Lie's matter before, Gu Qingwan has summoned many people from Guozijian.

Therefore, the people in this country prison have all seen Gu Qingwan.

It's really hard to sit down, if someone finds out.

Lu Yuan also knew that Gu Qingwan couldn't sit, and then said:

"Followed by Ha~"

With that, Lu Yuan pedaled the car and left, but as soon as Lu Yuan walked out of the gate, he was surrounded by a group of people.

Some Qingbei students took the notebooks in their hands and asked Lu Yuan about today's things.

It's just that there are some problems that these people don't understand.

Lu Yuan is not afraid of these people to learn, but he is afraid that these people will not learn.

Since the enthusiasm is so high, Lu Yuan will definitely not leave.

Lu Yuan sat on the bicycle, with one foot on the pedals and one foot on the ground, and glanced back at the carriageway behind him:

"You guys go first, I'll go home later."

After that, Lu Yuan began to explain to the students who were around.

There were a lot of students who came to ask, and everyone rushed to come.

This is even asked, by some people from the country.

This made the people of Qingbei University unhappy.

When even while shouting, he pushed the group of people from the Guozijian out:

"You're not our students here, go ahead!!"

As soon as the people from Qingbei University shouted, the classmates of Qingbei University also echoed it.

looked at the people around him, and even if they worked together, they directly hugged these people out.

This made the people of Guozijian angry, but they couldn't say anything.

After all, it's true that you're not a student here.

That's it......

Everyone is a member of the Guozijian, where do you go to be entertained?

I came here and was huddled out.

Although it was unpleasant, everyone couldn't say anything, so they could only stand on the periphery and listen.

Anyway, these student questions of Qingbei University are actually similar to everyone else, and they can be understood outside the crowd.

Next, Lu Yuan explained to these people.

About another hour later.

Lu Yuan couldn't stand it, where is this, this has been talking for more than an hour, and there are still many people around.

Really finished telling these people, Lu Yuan still went home to eat and didn't eat?

Immediately, Lu Yuan said directly:

"In this way, I will choose two student representatives, you will summarize all the problems tonight, and I will come to tell you tomorrow."

Lu Yuan turned on the system and found two high stars, three and a half stars, as the representatives of the students.

That's how I was able to get out.

When Lu Yuan rode back, he found that Gu Qingwan's carriage hadn't left just now, and had been waiting there all the time.

Lu Yuan rode the car side by side with Gu Qingwan's carriage and walked home.

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

"Why don't you go back, what are you waiting for me?"

Inside the carriage, there was a light snort, and Gu Qingwan said coquettishly:

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

This house is not waiting for your big shopkeeper to come to the table, who dares to move the chopsticks~"

Listening to Gu Qingwan's words, Lu Yuan smiled.

Is that~

Outside, Gu Qingwan is the emperor, but in his own home, he is the big shopkeeper~

……

Day 2.

Lu Yuan went to Qingbei University at half past eight.

This is now cultivating immortals at night, so I am not sleepy.

Cultivating immortals and meditating at night is equivalent to resting.

It's more refreshed than a night's sleep.

After Lu Yuan arrived at Qingbei University.

The students here have long been prepared.

Lu Yuan looked at it, hey, good guy, how many people are here?

This gaze swept over, and there must have been at least close to a thousand people!

The people of the prison of this kingdom...... All here?

Well......

It should be, because the people from Guozijian are still easy to find, and these people are sitting on the ground.

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

After Lu Yuan came, he didn't know who started it.

When Lu Yuan walked towards the high platform, the students of Qingbei University stood up in unison and said loudly:

"Good morning, Headmaster."

The students of Qingbei University have sincere admiration for 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 has respect for this only twenty-two-year-old Lu Yuan.

In just half a year, so many great inventions have been made.

The steam engine, the train, is even more cross-era!

Moreover, the principal of his own family is simply the all-round of all-rounders, not only in industry.

The yield of potatoes has doubled.

It directly solved the reduction of grain production during the winter flood in the south.

There are also mortars for the suppression of bandits in the south, and the latest invention some time ago, the ore refiner.

Each of these items is a five-body throw that everyone admires.

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

was called the principal by these people, and Lu Yuan was stunned.

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

"Sit down."

Then, Lu Yuan came to the podium, and after sitting down, he said:

"Did yesterday's question come to an end?"

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

Lu Yuan held a large enamel jar, leaned back on a chair, crossed Erlang's legs, and answered the students' questions while drinking tea.

Get rid of the image of an old cadre.

It took more than half an hour to answer all the questions clearly, and it was ten o'clock at this time.

Hurry up and give a lecture, until twelve o'clock in the afternoon, there are still two hours to go.

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

"Yesterday, I left you with an assignment, do you have an answer?"

Then there are a lot of people who say their own conjectures.

But the answer is obvious......

None of them are right.

It's normal, after all, it's just the beginning.

And these individuals didn't learn this thing, so Lu Yuan immediately smiled:

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

First of all, water has a singular property, at four degrees, it is the densest and the smallest in volume.

After zero degrees, the volume of water begins to increase, and it is 10 percent larger than at room temperature.

So, what about when this tofu is frozen......"

This is followed by a two-hour presentation.

Lu Yuan is now preparing for classes when he goes home at night, so where is this going to be, and when it comes to it, Lu Yuan has designed it.

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

One after the other.

The mood of everyone was very high.

This is especially true for the students of Guozijian!

After all, for the students of Guozijian, this kind of class method has never been seen before.

And these things that Lu Yuan said were also things that the students of Guozijian had never come into contact with.

After all, if you can enter the Guozijian at the age of thirty.

Before this life, he must have read the sage book every day, and he didn't know anything about life.

Therefore, these things that Lu Yuan said are for the people of Guozijian.

It's a real rarity.

At twelve o'clock in the afternoon, the morning class is over.

Everyone goes to the cafeteria to eat first.

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

Yesterday, there was a simple cafeteria of Qingbei University, and there were no tables, chairs and benches in it.

It's almost finished today.

The students of Qingbei University all went to eat, Lu Yuan also went to a small room for dinner, and today Gu Qingwan also came.

As for the students of Guozijian.

That is naturally the return to the country and eats it.

Or go to the street to eat.

After all, this is not a place to care about the food of these people.

Come to the class, come to eat, no.

……

"Oh, the principal also personally cooks food for the students~"

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

Listening to Gu Qingwan's jokes, Lu Yuan didn't make a mistake, but just raised his eyebrows and said:

"The funds approved by the Ministry of Rites are too small, you see, just one meat dish, and the others are all vegetarian.

The people of us here will be the pillars of the country from now on, how can we just eat this? ”

Listening to Lu Yuan's words, Gu Qingwan hurriedly said:

"Go back today, my sister must train the people of the Ministry of Rites well!"

After Lu Yuan sat down, he put down the meat and vegetables and raised his eyebrows and said:

"True training and false training?"

Gu Qingwan raised her eyebrows and said:

"Hey~ You little thing, you still don't believe your sister, when did your sister lie to you, go back and let your sister directly ask the household department to allocate funds."

Hearing this, Lu Yuan nodded with satisfaction and said:

"This is okay, three dishes and one soup in the future cannot be less."

Gu Qingwan looked at Lu Yuan, her eyes were full of doting, and said:

"Okay, good~ Sister is all up to you~"

……

After eating at noon, Lu Yuan was not polite.

wiped his mouth, and in Gu Qingwan's coquettish voice, Lu Yuan slept directly on Gu Qingwan's soft thigh.

Lu Yuan pillowed up directly without warning, causing Gu Qingwan to look disgusted.

But soon, Gu Qingwan was gently patting Lu Yuan's back with a gentle hand.

He hummed softly, as if he was coaxing the child to sleep.

Afternoon.

Two o'clock.

Lu Yuan continued to go to class.

However, there were significantly fewer students this afternoon than there were students in the morning.

The main thing is that half of the students of Guozijian do not come.

Lu Yuan inquired and found out that this is the second assistant of the cabinet today, and Yan Shijin is lecturing in Guozijian.

Many of the students of Guozijian went back.

Lu Yuan nodded, but he didn't say anything, it didn't matter, this Qingbei University was not going to Guozijian and the gang in the first place.

Immediately, Lu Yuan began to lecture again.

And at this time, Guozijian is here.

Yan Shijin looked at the huge classroom with half of the empty seats, completely confused.

Huh??

No.

What about my students?!!

Where's my protégé?!!

Where are all my students?!!

Thank you for the 588 book coin reward of Brother Flower Face Cat (Feng), thank you very much~
