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

"Do you think these low-temperature kilns can reach that temperature?"

Upon hearing this, Li Cheng smiled bitterly for a while and stopped talking.

Although Li Cheng does not know how much the temperature of the low-temperature kiln can reach, it is definitely unable to calcinate iron.

In fact, on the first day of building the low-temperature kiln, they were wondering whether they could create some iron fire-gathering plates.

For this reason, they also specially found some iron tools that they could not use at all and threw them into the low-temperature kiln.

But no matter how long it takes to calcinate, the best result is that the iron tool becomes a little dark red and slightly softened.

There is still a long way to go before being forged, let alone melting.

So after Ren Yan said this, Li Cheng had no thoughts.

However, at this time, Ren Yan looked at the students in Class 9 with great interest:

"Actually, it's not bad for you to make cement. Teacher, I can take you from a low-temperature kiln to an iron smelting furnace. With the temperature of the iron smelting furnace, it's okay to burn some cement."

Upon hearing this, the students' eyes lit up.

But then it became dim because of Ren Yan's next sentence.

"But don't think about building this house for the time being. And when you can boil cement, it's almost time for school to start."

Upon hearing this, the students were speechless: "Then what else do you want to say?"

"The final result is not understood in a short period of time."

"It's fun~" Ren Yan smiled on his own.

"."

The students were speechless.

Mom, if you didn’t beat you, you would definitely be able to see the students’ anger today.

Is there anyone teasing my students like this?!

The students in Class 9 felt a little frustrated.

And netizens were completely happy.

Seeing this scene where Ren Yan teases the students of Class 9, they feel relieved from the bottom of their hearts.

Isn’t it just this one for your own good?!

Sure enough, Teacher Ren still understands them!

But then, they became a little curious.

Teacher Ren can not only build a house, but can he really smel out the iron?

Isn't this thing a bit too out of the ordinary?

Is this something a teacher should know?!

I couldn't help but feel a little expectation in my heart.

They were looking forward to Ren Yan being able to create something else.

At this time, Ren Yan put his mind back on building a brick house.

After teasing his students for a while, Ren Yan was in a good mood and soon found the tree for what to use.

As everyone was watching, Ren Yan hugged these slightly as thick as a bowl and jumped into the foundation again.

Started to fix the trees along the four corners of the foundation, and explained:

"Remember, even if it is a brick house, you need to set a contour first."

"And this time, unlike the previous thatched hut, we still need to create a roof on these outlines."

"So these trees must be as thick as possible, and the thickness of the bowl mouth is the most suitable."

While speaking, Ren Yan had completely set the trees at the four corners, and at the middle of the four corners, two trees with the opening of the "Ya" at the top were inserted.

Then another thicker tree was sandwiched between the two trees.

"This thickest piece of wood is the beam of the house. After all the surrounding walls are fixed, you can build a ceiling profile along the beam and then evenly place the tiles on it."

"The firing of tiles is the same as that of stone bricks. I won't go into details here. Just burn some tiles yourself."

After saying that, without waiting for the students to react, Ren Yan began to build the stone bricks along the surroundings of the foundation.

To be honest, he is a little guilty now.

Ren Yan forgot about this tiles at the beginning. It was not until now that he needed to build a house that he remembered it.

It's really a bit suspicious of being hindsight.

However, in order not to let the students in Class 9 despise him, Ren Yan still skipped this part with his strong psychological quality.

‘I hope these little bastards don’t see it.’

Ren Yan prayed slightly in his heart.

But his expression was still calm, and even after building two bricks, he continued to talk:

"The step of laying bricks is actually very simple. As long as you stick around the foundation and build them in the form of bricks and clay, there will be no problems."

"But there are still two key points to pay attention to."

"First, when building, it is best to stagger the upper and lower bricks between the upper and lower bricks and not be completely parallel. This will make the wall stress area more uniform and the impact it can resist will be greater."

"The second is that when the wall is about to build a foundation, the circle of bricks must be half above the foundation and half below the foundation. Never let the connecting layer between the two bricks be level with the foundation."

"In that case, if some powerful external force appears, the house will easily break from the middle. It is a very dangerous behavior. Do you understand?!"

After saying that, Ren Yan looked at the students in Class 9 again.

After looking at each other, the students always felt something was wrong, but they didn't have time to think too much, so they could only nod according to Ren Yan's words.

And remember these two key points in my heart.

After demonstrating some of the main knowledge points, Ren Yan stopped talking.

Instead, quickly use clay and stone bricks to build up the base layer.

Soon, the walls on all sides, which were as high and low as the wood they had inserted before appeared in front of everyone.

There are clear locations of doors and windows on one side.

It made netizens feel moved.

This teacher Ren is really good at building brick houses!

They had some doubts before, but now it seems that their situation is still small!

After these four walls appeared, Ren Yan used the previous clay and some gravel to reinforce the four trees at the corners.

The combination of clay and gravel completely wrapped around the four trees before giving up.

Then weeds were found to cover the beam, which barely replaced the effect of the tiles.

At this point, a brick house is basically completed.

Netizens looked at the time, and it took almost three hours from construction to completion.

Although the size of the house looks average, they can still feel the unique sturdiness of the brick walls.

This thing looks much stronger than the thatched huts in front of it!

The students in Class 9 also felt the same way.

Therefore, after Ren Yan completed it, they scattered birds and beasts without saying a word.

They all made a simple move of their original thatched hut.

The residential area has been vacated with a large area.

Now that there are brick houses, who will let thatched hut occupy this position!

If they didn’t just take it off, it would be their greatest favor!

Back then, the main reason was that I had no place to sleep at night after it was demolished.

After determining the location of each brick house.

The students began to lay the foundations as Ren Yan looked.

For a moment, the entire farm became more and more lively again.

Netizens were also a little moved when they watched this scene.

Start to conceive the possibility of building a brick house by yourself in the barrage.

However, because he couldn't burn bricks, he had to give up this idea temporarily.

And after reaching a unified state, I must ask Teacher Ren to talk about the whole process of burning bricks after taking time!

Otherwise, wouldn’t the construction of their brick house be in vain?!
