Hearing Ren Yan's question, the students were slightly stunned.

How can you be so dignified and ask questions?

In the past, there was no such operation...

Aren't these the 'traditional' ways of teaching?

Make a question for students to answer.

This is used to test whether the students have learned the previous knowledge points.

But when this matter is put on Ren Yan, the students always feel weird.

I feel that everything reveals a feeling of inappropriateness.

And...

The most critical thing is.

Other teachers have asked questions, but they have explained them before.

Why did you skip this explanation when you got to your own teacher?!

Just let yourself guess?

Isn't this the difficulty of the naked dew?!

The students stared at Ren Yan silently, wanting to see Ren Yan's embarrassed appearance.

Seeing this, Ren Yan touched his chin, thought slightly, and said:

“emmm...”

"Let you think about it, it seems to be a little difficult for you."

"So be it! If any of you can say it right, the teacher will give you a reward. ”

"It's a kind of quiz with a prize!"

"What we test is your ability to observe and associate!"

"As for what the reward is, exactly."

"You teachers, I really don't have anything to do right now."

"So this reward can only meet one of your requirements."

"As long as it is within a reasonable range, you can make any request to the teacher and me, and as long as the teacher can do it, I will never regret it."

"How? Would you like to get involved? ”

"If you don't participate, then I'll just announce the answer, let's not waste time."

After saying that, Ren Yan slowly looked at the students of Class 9, and at the same time took out his mobile phone to turn on the timer.

"You only have 30 seconds to think about it, and if no one answers after 30 seconds, it will be regarded as a waiver, and I will go straight down!"

Hearing this, the students were entangled for a while.

Although it seems a little unreasonable, let yourself think hard.

However, this reward, to be honest, is quite attractive to the students of Class 9.

After getting along for so long, they also have a certain understanding of their own cheap teacher.

It's not all-powerful, but at least he's a polymath.

It is much better to be able to make a request to him than to a certain degree.

And more importantly, as long as this requirement is within the ability of the other party, the other party will do it.

Wouldn't that be equivalent to one more chance to let the other party dare or dare?

Even if it's not used to get help, it's a good choice to look at your own teacher's embarrassment~

And most importantly, it seems that there is nothing to lose by guessing wrong.

This is simply a prostitution!

At this moment, the students looked at each other, and they all read the fire called 'Tongdao' in each other's eyes.

Then they strained their heads:

"Teacher Ren, we will definitely participate in this activity!"

"Don't worry! We'll be able to guess for sure! ”

Then they started brainstorming around the mud cake with great interest.

And Ren Yan on the side let out a successful laugh in his heart.

This method of giving a fishing hook to induce students to think on their own initiative is really wrong!

And the most important thing is that you have nothing to lose.

What, you said that Ren Yan promised the student that he would meet the other party's request?

Not to mention, these students can guess if they can guess.

Even if you guess, what can you do?

Ren Yan said it before, under reasonable circumstances~

Plausible~

Isn't this thing Ren Yan himself decide?!

If the students are doing something simple, or looking for something to learn, Ren Yan will also help.

But if they want to make themselves a 360-degree split in the air, this kind of operation will be embarrassing when they hear it.

Then Ren Yan didn't suggest letting the cubs of Class Nine know at all.

What is the special thing, everything is based on the final object!

What is the final interpretation right belongs to the merchant!

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

Let them learn the laws of society in advance.

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

At this moment, Ren Yan was very proud.

Fight with yourself?

These little cubs are a little too young~

When you put forward this condition, how can you not guard against them, how can you let them do whatever they want?

This kind of unwittingly leaving a text trap in the words is simply a basic exercise!

It is also the first lesson for all 'stunned youths' after entering society.

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

In recent years, there are not many teachers who are so 'considerate' for the sake of children~

......

When Ren Yan was smug, the students of Class 9 had already conceived about it.

It didn't take long for them to give their answers.

However, none of these answers are reliable, except for brain-blowing.

What Ren Yan made this thing for ventilation.

What Ren Yan made this thing to make a fire.

And every answer explained by the head is the truth, and even Ren Yan was a little caught off guard.

For example, the student who started the fire.

The reason he gave was that it looked the same as the frisbee in the Drill Wood Fire suit.

The reason for drilling so many eyes is to adapt to various types of wooden sticks at that time to achieve a maximum utilization effect.

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

And uphold Ren Yan's reasons for telling them about some 'psychology' not long ago.

He had reason to suspect that this thing might not even have anything to do with the entire low-temperature kiln, purely because he wanted himself and others to analyze Ren Yan's inner thoughts at this moment.

And he, on the other hand, has seen through all this!

As soon as this explanation came out, not only the students were stunned, but they also exclaimed the big guy.

Even Ren Yan was a little impressed by this student, in terms of the ability to talk nonsense, this kid is simply a genius!

Then after giving a compliment without hesitation, Ren Yan glanced at the other party:

"The story is well told, but I'm sorry, you're still going in the wrong direction."

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

"This is indeed the core of the cryogenic kiln."

"And everyone, this is a low-temperature kiln, it's a fire, shouldn't we let it get some edge with the fire?"

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

As he spoke, Ren Yan glanced around the students again, and the students fell into deep thought again.

After a while, there was finally a student's lack of confidence:

"Teacher Ren, I think this thing is to increase the flame..."

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

This student is not big, but he is also quite honest, and he belongs to the kind of ordinary people who look like a public and disappear immediately when he throws it into the pile.

However, for this student, Ren Yan still has a bit of an image.

This kid's name is Shi Lei, although the name is very strong, but in fact, he is only a little stronger than Li Qi.

I don't have much presence in the class.,It's the type that is average.,It's the easiest to forget a few years after graduation.。

But now, he's the first to say the right answer.

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

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

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

"Mainly because I thought of the dirt pit we used for cooking during our outings before, which is very similar to this one."

"At that time, the pit was used to make fires."

"Teacher Ren, this mud cake you made is very similar to honeycomb coal."

"I thought it might have the same effect as honeycomb coal."

"Honeycomb coal can gather flames to achieve a warming effect and intensify 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, right!" ”

"We replied just now, you have never reacted like this!"

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

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

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

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

"To put it simply, it effectively aggregates the energy of the flame and raises the temperature."

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

Hearing this, the other students also looked at Shi Lei, and Li Cheng directly hugged Shi Lei's neck: "That's it, stone!" ”

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

"Why are you always so low~"

Hearing this, Shi Lei could only smile reluctantly.

Ren Yan shook his head slightly in his heart, he knew that this kind of thing could not be changed just by saying it, it could only be done slowly.

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

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

What made Teacher Ren stand upside down, what asked Teacher Ren to perform constipation, and what asked Teacher Ren to talk about the previous embarrassment.

Anyway, it's all about making Ren Yan embarrassed.

Ren Yan had a roll of eyes in his heart, these guys really didn't hold back any good fart!

'Good thing I was prepared!' ’

Ren Yan was slightly complacent.

What do you say about this wave?

It's just that I predicted your prediction!

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

"Teacher 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 for a moment and nodded slightly:

"Absolutely."

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