Let you teach, you play games with the worst class?

Let them have a good experience of the "beating" from the "society" people. '

Let them learn the laws of society in advance.

This is the perfect plan to kill two birds with one stone~

At this moment, Ren Yan was very proud.

Fight yourself?

These guys are too young~

When I put forward this condition, how could I not guard against them, how could I let them do whatever they wanted?

This kind of writing trap left in the speech without anyone noticing it is simply basic practice!

It is also the first lesson for all the "slutty youths" after entering the society.

Thinking about it, Ren Yan was a little moved by herself.

These days, there are not many teachers who are so 'considerate' for children~

......

While Ren Yan was complacent, the students in Class Nine had almost come up with an idea.

After a while, they gave their own answers.

However, these answers are not reliable except for brain opening.

Why did Ren Yan get this thing for ventilation.

Why did Ren Yan get this thing to make a fire.

And every answer was explained clearly and logically, even Ren Yan was a little caught off guard.

For example, the student who lit the fire.

The explanation he gave was that this thing looked the same as the Frisbee in the wood drilling suit.

Drilling so many holes is to adapt to various types of wooden sticks in time to achieve a maximum utilization effect.

After that, Ren Yan can use this thing to start a fire to burn bricks.

And uphold some of the 'psychological' reasons that Ren Yan told them not long ago.

He had reason to suspect that this thing might not even have anything to do with the whole low-temperature kiln, it was purely using this thing to let himself and others analyze Ren Yan's inner thoughts at the moment.

And he has seen through all of this!

As soon as this explanation came out, not only the students were dumbfounded, but they exclaimed, boss.

Even Ren Yan looked at this student with admiration. In terms of nonsense ability, this kid is simply a genius!

Then, after giving a compliment without hesitation, Ren Yan gave the other party a blank look:

"The story is pretty good, but I'm sorry, but your direction is still wrong."

"After all, the old man is not a devil, so he can't make fun of you like this."

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

"And everyone, this is a low-temperature kiln, and it's for lighting a fire. Shouldn't we let it have something to do with the fire?"

"Although your brains are quite big, you still have to pay attention to some basic laws when you open your brains~"

After speaking, Ren Yan glanced around the students again, and the students fell into deep thought again.

Not long after, a student finally spoke with a lack of confidence:

"Teacher Ren, I think this thing increases the flame..."

As soon as this remark came out, Ren Yan's eyes flashed immediately, and he looked at the student.

This student is not big, and looks quite honest. He belongs to the kind of ordinary people who look like ordinary people and disappear immediately when thrown into the crowd.

But for this student, Ren Yan still has some impressions.

This kid's name is Shi Lei. Although his name sounds strong, he is actually a little stronger than Li Qi.

He doesn't have much sense of presence in the class, and belongs to the type that is average in everything, and is the type that is most likely to be forgotten after a few years of graduation.

But now, he is the first person to give the correct answer.

Ren Yanrao looked at Shi Lei with interest: "Xiao Lei, tell me, what do you think?"

For a moment, all the students looked at Shi Lei.

Shi Lei became a little nervous for no reason, and replied weakly: "That..."

"Mainly because I thought of the earth pit we used to cook in our outings, which is very similar to this one."

"And at that time, the earth pit was used to make fire."

"Mr. Ren, the mud pancake you made looks like honeycomb coal."

"I just thought it might have the same effect as briquettes."

"Honeycomb can gather flames to achieve the effect of gathering and intensifying combustion..."

"so..."

"So you think this thing has the same effect?" Ren Yan asked with a smile.

Shi Lei nodded.

The students immediately looked at Ren Yan and asked, "Teacher Ren, isn't that right?"

"We answered just now, but you have never had such a reaction!"

"That's right!" Ren Yan nodded: "Shi Lei's answer is correct."

"This thing is indeed used to gather the flames and increase the temperature, and it is also the most important part of firing stone bricks."

"Without the existence of this thing, the temperature is simply not enough."

"As for why it gathers flames, you can go back and read the relevant physics books, especially the energy conversion. I don't bother to talk to you here, it's too complicated."

"To put it simply, it effectively gathers the energy of the flame and increases the temperature."

Then Ren Yan looked at Shi Lei again: "Ah Lei, the answer is correct, you can be more confident, there is no need to be so submissive all the time."

Hearing that other students also looked at Shi Lei, Li Cheng put his arms around Shi Lei's neck: "Yes, Shi Lei!"

"You don't have to be like this at all, just smile more, how nice~"

"Why are you always so low~"

Hearing this, Shi Lei could only forcefully smile.

Ren Yan shook his head slightly in his heart, he knew that this kind of thing is not something that can be changed at will, but can only be done slowly.

Then he looked at Shi Lei and asked, "Okay, do you have any requests now?"

Hearing this, the students began to come up with ideas in a hurry.

What made Teacher Ren stand on his head, what made Teacher Ren act out constipation, and what made Teacher Ren talk about the embarrassing things before.

Anyway, it was all aimed at embarrassing Ren Yan.

Ren Yan rolled her eyes in her heart, these guys really didn't hold back anything good!

'Fortunately, I have prepared in advance! '

Ren Yan felt slightly complacent.

What about this wave?

It is simply that I predicted your prediction!

However, after a while of entanglement, Shi Lei said weakly:

"Mr. Ren, can I use this reward in the future?"

"I haven't figured out how to use it yet."

For a moment, the students were disappointed.

Only Ren Yan thought briefly and nodded slightly:

"of course can."

"As for the deadline, let's wait until you graduate~"

Chapter 173 Brick Burning Completed!

"The deadline will last until you graduate~"

Hearing Ren Yan's answer, he looked at Shi Lei's nodding.

The students in Class Nine suddenly felt a little messy.

Why did you agree so easily?

What a chance to play tricks on Teacher Ren~

Why did Shi Lei postpone it so easily?

Adhering to the mentality of trying again, the students in class nine continued to persuade.

The reason is nothing more than that.

After this village, there will be no such shop~

You should accept it as soon as you see it, and what you get is yours.

All in all, it is for Shi Lei to have fun in time, not to waste this rare opportunity.

But in the end Shi Lei shook his head and rejected all the students' proposals.

It's not that he's not tempted, but he always feels that such a good opportunity, it's a waste to do some of these things.

If his classmates could offer any constructive suggestions, he might listen to them.

But now, Shi Lei still wants to save this opportunity and use it when needed in the future.

"Okay, okay, stop encouraging Shi Lei. With this effort, it's better to increase your knowledge and hold the right to make demands in your own hands next time. Don't you want to do what you want?"

Ren Yan at the side spoke calmly.

Hearing this, the students in Class Nine were all taken aback, and immediately regained their spirits: "Teacher Ren, is there another time for this kind of prize quiz?!"

"Hmph, who knows~" Ren Yan shrugged, but instead of answering directly, she changed the topic: "But for now, let's continue to solve the problem of the low-temperature kiln."

"Otherwise, I'm afraid you won't be able to live in brick houses when school starts."

With that said, Ren Yan squatted next to the mud cake again, and began to pile up dirt along the edge of the mud cake.

"Now, we have the most basic means to increase firepower, so the next step is to make a basic building shell."

"There are various styles of low-temperature kilns, as long as they can accommodate the things you are calcining, in theory, you can make whatever you want."

"However, there is also a basic requirement during this period, which is to allow the low-temperature kiln to perfectly eat the firepower below, so the initial base must be stacked along the mud cake we made before. It is best to be able to Make it a tight fit.”

"In this way, the firepower will not be leaked, and the efficiency will be improved a lot."

"Of course, if you want to fire more bricks at one time in the future, you can make the clay cake bigger. Here I will simply tell you the principle, and it will not take much effort to make it so big."

While speaking, Ren Yan began to build up the soil layer by layer on the fixed base.

On the other hand, the students in Class Nine were slightly puzzled: "Mr. Ren, since it is necessary to light the fire, does this mud cake really not need to be dried before use?"

"If it's wet, will it affect the spread of firepower?"

Hearing this, Ren Yan looked back at the students with a little appreciation in his eyes: "That's a good question."

"Actually, under normal circumstances, the fire hole is mostly made of some iron products, and there will be no such problem as you mentioned."

"But now, after all, the environment is poor, so we can only use soil."

"Theoretically speaking, drying in the sun does improve some effects, and it is definitely better than wet."

"However, it is not impossible to use the wet one, but we need to light a fire first to dry it up. By the way, check the entire shell of the low-temperature kiln to see if there is any place exposed to fire."

"It can be regarded as killing two birds with one stone, and it can save a lot of time."

"So I didn't go to dry it."
