Listening to Ren Yan's words, the students in Class 9 looked at each other in shock.

How can it be so troublesome to build a brick house?

Can't there be a simple and easy way?

At this moment, the students suddenly felt that they were a little careless.

It seems that building this sturdy house is not as easy as they thought.

Seemingly sensing what the students were thinking, Ren Yan coughed twice:

“Do you think it’s easy to build a brick house?”

"Even to build the simplest brick house in a rural area, it would take one person at least half a month."

"As for you, even if you have a large number of people, it will probably take you about a week to complete it all together."

"Moreover, starting from the bricks will also help you understand more about the origin of each brick house, which can expand your narrow knowledge."

Speaking of this, Ren Yan paused for a second, then shrugged:

"Of course, then again."

"Teaching you to build brick houses was not part of my plan in the first place. You begged me to teach you. Of course you can choose not to learn now."

"But next time something like this happens again, you won't come to me."

"It is very demeaning to have someone teach you something and then not learn it because it is too difficult."

"You teachers, you are very tired now, and suddenly you don't want to teach anymore."

"How about we break up?"

Finally, Ren Yan looked at the students in Class 9 with a smile.

The students felt a chill in their hearts for no reason and hurriedly apologized: "How could you, Teacher Ren~"

"Look what you said, we were just a little bit surprised by how complicated it was~"

"How could it be that you find it troublesome?"

"That's right, Teacher Ren."

"We just feel that you know too much, and we feel a little bit emotional~"

"How could it be that I don't want to learn~"

"You misunderstood!"

The students racked their brains one after another, trying to make Ren Yan ignore their expressions just now.

What he said at this moment was extremely sincere.

It is simply a heart of fists, visible to the naked eye.

However, Ren Yan's heart felt numb for no reason, and she felt goosebumps all over her body.

'How come these students are so familiar with flattering each other now?'

‘Who the hell did you learn this from?!’

Ren Yan shuddered slightly and looked at the students in Class 9 with disgust: "Don't you think it's unconscionable to say such shameless words?"

student:"."

'Minato! Didn't we just make you forget about that windlass?!'

'Is it easy for us to rack our brains to think of words of praise?!'

'Now you say you dislike it and you dislike it. Do you know that this hurts our innocent hearts!'

The students were complaining crazily in their hearts.

But on the surface, I can only maintain a polite yet elegant smile.

For a moment, Ren Yan and the students in Class 9 looked at each other in silence.

The atmosphere became a little awkward.

"Ahem!"

"Okay, since you are willing to learn, then I will continue to teach."

In the end, Ren Yan cleared her throat again and opened a new topic.

"As for the low-temperature kiln, the materials required are relatively simple."

"It's clay that can be found everywhere. As long as it has enough viscosity, it is a suitable material."

"Generally in the Dragon Kingdom, as long as there is a piece of land, the soil in it can be used to make a low-temperature kiln."

"If you feel they are not sticky enough, you can add a little more water."

"That's why I asked you to bring water."

While talking, Ren Yan randomly took out a part of the soil from the soil pile, mixed it with water, and slowly started kneading it.

"You can see that I am in the process of making a low-temperature kiln now."

Following the words, Ren Yan's movements became faster and faster.

A piece of soil was immediately flattened and rounded by it, and it was repeatedly ravaged.

The students were confused for a while. After looking at each other again, they all saw deep confusion in each other's eyes.

Can a building made of fired bricks really be made in such a playful way?

The students asked their own questions.

Hearing this, Ren Yan happily patted the kneaded mud ball on the ground: "What else?"

"You don't think that the so-called low-temperature kiln is something fancy, do you?"

"To put it bluntly, he is actually a by-product of playing in the mud."

"There's not much difference from what you used to do with urine mud."

"It's just applying some simple chemistry and physics knowledge."

"Do you think it's difficult to do something that even tribes in ancient times could come up with?"

While speaking, Ren Yan put his hand on the mud ball and began to slowly flatten it.

The students looked at each other and their faces turned slightly red:

"Teacher Ren, we are a new generation of young people. We are so young that we can't get along with each other~"

"Pull it down~" Ren Yan curled her lips: "When I was a child, the wet mud was almost engraved into human genes. Who hasn't done such stupid things as a child~"

"Even if it's just curiosity, it's understandable. There's no need to be ashamed of it."

"At the very least, your teacher will..."

Halfway through his words, Ren Yan suddenly felt that something was wrong, so he quickly cut off the topic and focused his attention on the ball in his hand again.

"Ahem, okay, now the first step is completed, you should watch carefully next, don't think about what is there and what is not!"

While talking, Ren Yan started to open holes in this mud cake-shaped thing.

From top to bottom, from left to right, more than a dozen holes were opened, large and small, until the whole body was covered with mud cakes, it stopped.

The students were speechless for a while.

They were confused because they didn't bring up this topic themselves.

How do you say it's gone?

At this time, they couldn't help but feel a little regretful.

In the end, I still didn’t hear anything embarrassing about my teacher!

But at this time, they did move their eyes to the mud cake in front of Ren Yan.

They are still a little curious about how this mud cake became a low-temperature kiln.

After poking the hole, Ren Yan carefully held the mud cake and placed it on a pothole.

This hole was dug by Ren Yan just now during the preparation process.

The purpose is to put this mud cake on it.

Therefore, the size of the potholes was controlled by Ren Yan to a moderate level.

After he placed the mud cake firmly on the pothole, he clapped his hands and let out a breath.

"Okay, now the most critical step of the low-temperature kiln has been completed."

"This thing is the core of the entire low-temperature kiln."

"Then here's the problem."

"Now you can guess what role this mud cake that looks like a colander will play?"

While speaking, Ren Yan's gaze swept across the faces of all the students.

The corners of his mouth also curved into a trademark smile.
