After confirming that the plane was received, Ren Yan was too lazy to say more about what was missing.

Asked Wang Bo to spread the drone in his hand and took the students from Class 9 to walk towards the pile of low-temperature kilns built together.

Because the farm area has been allocated.

This time the students did not build them in a scattered manner, but instead gathered together.

This is convenient for Ren Yan to use bricks.

As for whether the drone will fly around if it does not continue to be held hostage?

Ren Yan was not worried about this at all.

Unless the staff who control the drone doesn't want to do it, they will definitely not dare to let the drone sway.

Netizens have spent money to watch this live broadcast now.

This is if the operator fails to see what they want to see because of the 'mistake'.

Then you don’t have to think about it, netizens must have smashed the staff immediately.

How irritable are netizens nowadays ~

And it seems that the staff understand this.

After the drone was released by Wang Bo, he adjusted his position slightly, stabilized at a position slightly higher than Class 9, and slowly moved forward with Class 9's pace.

That perspective fully reflects the two words "Professional".

As for him, he was a little sad.

I originally thought of going to a wilderness to conduct a drone live broadcast, but it should be quite comfortable.

But I didn’t expect that the ‘working sense’ here is actually stronger than when I was in the program team.

When he was in the program team, he still had some "autonomous" authority, but here he was completely led away by someone~

The drone operator was a little unbalanced at this time.

Ren Yan has already brought people to the area of ​​the low-temperature kiln.

After cleaning up a place casually and taking a shovel, Ren Yan looked at the students in Class 9 and the drone floating above their heads:

"Okay, after a while ago, you have fired enough bricks through a low-temperature kiln."

"Now it's time to turn these bricks into houses!"

"As for what you need, you have seen it."

"A shovel, a pile of bricks and enough soil."

As he said that, Ren Yan began to draw around with a shovel. After circled a square position, Ren Yan took the shovel to excavate without saying a word.

"The first step in building a brick house is definitely to create a foundation."

"Under normal circumstances, building a base requires steel bars, concrete and other things. If it is a little bit original, hard bamboo is also needed to strengthen it."

"And the depth will generally look like dozens of centimeters. If the floor needs to be built, the deeper the depth will definitely be. After all, only in this way can the house stand on the ground more steadily."

"If we look at the principle, it is similar to plant growth. After all, things that grow from the ground are often more resilient."

"As for more specific reasons, there are mechanics and materials science, you can take a look at this part in private."

While speaking, Ren Yan had already dug up a considerable position.

Because the land on the farm is relatively soft, it is not very difficult to dig.

The students in Class 9 also wrote down the two subjects of mechanics and materials science.

After following Ren Yan for so long, they have become completely used to Ren Yan's behavior of suddenly inserting other knowledge points when he speaks.

If they are interested, they will still go and see it if they are bored in private.

After so long, they have seen a lot of things with a purpose.

And netizens were a little moved.

‘For so long, this familiar feeling has finally come back!’

‘They can watch the live broadcast happily again!’

And because this time I saw it with real money.

Therefore, they watched more seriously than the students in Class 9.

All the money has been spent, so it can't be spent in vain!

That's their truest thoughts at this moment.

Even they themselves did not realize that such a change would occur.

After digging for a while, Ren Yan spoke again:

"However, what I just said was building a house under normal circumstances."

"It does not apply to what we need to cover now."

"What we want to build now is the local brick house in the countryside."

"Because the area is not large and there is no need to bear more pressure, the foundation does not need to be deep, and a dozen or twenty centimeters are enough."

"And there is no need for support from steel bars or other things. As long as you ensure that you can have a certain depth underground, it will not collapse."

As he said that, Ren Yan had completely dug up the foundation he needed to prepare.

After roughly measuring the height with a shovel, Ren Yan jumped out of the foundation.

This foundation covers a small area, only about four or five square meters, and the depth is only about ten centimeters.

Because of the demonstration, Ren Yan was too lazy to make it too big and deep. If you have any meaning, just finish it.

This is not because Ren Yan is irresponsible, but because he can't do it.

I already have a brick house, why do I have to work hard to get a new one?

Live for the students?

That would be even more unreasonable.

It is better for students to build their own houses.

Only in this way can they master a knowledge more effectively.

And what you make yourself feel more accomplished~

This is their original words.

As a teacher who starts from the perspective of students, how could Ren Yan bear to peel off their rare experience?

So at this moment, Ren Yan, who cut corners, had no burden in his heart.

"Teacher, what's next?!"

Seeing Ren Yan jump out of the foundation and throw down the shovel, the students in Class 9 couldn't help but ask curiously.

"Next?" Ren Yan looked back at them and replied naturally: "It must be building a house, otherwise what else can you do?"

"But before that, there is indeed another task to be completed."

"We need to mix the digging soil, water and wood ash to form some clay with viscosity."

"They are the main support for building brick houses."

While speaking, Ren Yan had already brought some water from the well not far away.

Then some wood ash was removed from the nearby low-temperature kiln.

After a little comparison, I started to stir.

After it became a sticky bun, Ren Yan stopped the movement in his hand and said:

"This pile of clay is mainly used instead of cement, which can perfectly bond between two acre bricks."

"Although the effect is certainly not as good as cement, because the materials of adobe bricks and these clays are almost exactly the same, the bonding between them is not actually very poor."

"It's more than enough to build a relatively sturdy brick house."

After Ren Yan said that, he searched for what kind of wood was nearby.

Although now there are foundations, bricks, and adhesives.

But the most basic framework still needs to be built.

However, just as Ren Yan was looking for materials, Li Cheng spoke curiously: "Teacher Ren, since this thing is not as useful as cement, why don't we use cement directly?"

Upon hearing this, Ren Yan turned around and gave the other party a blank look: "Nonsense, do we have cement now?"

Li Cheng scratched his neck embarrassedly: "Teacher Ren, that's not what I mean. I mean, why don't we make cement directly?"

"Because I can't do it." Ren Yan answered casually:

"Although the cement formula is not difficult, it only requires some limestone, clay and a small amount of iron powder and some dispensable gypsum."

"But it requires calcination, and the temperature required to reach is about the same as the melting point of the iron."
