Outside the warehouse.

A vote of students plus drones fixed their eyes on Ren Yan not far away.

The current Ren Yan has not started work yet, but keeps pulling some things from the merchants near the warehouse.

What planks, charcoal, large aluminum basins, etc.

It didn't take long for a pile to pile up at the door of the warehouse.

Only then did Ren Yan clapped his hands and looked at the students:

"Fumigation, as the name suggests, is fumigation and steaming."

"Actually, to put it bluntly, it's a sauna that you use when you take a bath."

"The difference is one steamed man and one steamed wood."

"One needs to keep pouring water on the charcoal, and the other can't move himself, so he has to let someone else do it."

"So, our ultimate goal is actually to make a sauna out."

"Let the wood experience the warmth of the world."

"But after all, there are different types of buildings, and the specifications used are also different."

"Just like the wood fumigation we want to make now, as long as it can stay quietly in it, the temperature is enough!"

As he spoke, Ren Yan began to take a pen and paper and began to draw a design drawing.

The drawings are very abstract, with all kinds of chaotic lines, and they look like the original sketches.

But there is still no shortage of what should be there.

Students can easily understand this picture.

From the backing plate for laying the wood, to the material chamber for charcoal burning, to the water chamber under the timber, everything is clearly visible.

And the whole looks like a large cage drawer, except that this cage drawer is cylindrical.

The only thing they couldn't understand was that the 'cage drawer' resembled a villain with two balls, blowing in the wind, and they didn't know what it was for.

But they didn't rush to ask, anyway, we'll find out later.

At the moment when the design drawing was completed, Ren Yan began to take the tool and get up and down.

The saw bow, which was previously thought to be redundant, also came in handy at this moment.

I saw Ren Yan grasping the saw bow in one hand, stepping on the wooden board placed on the bench with one foot, and after finding the right angle, he threw off his arms and stood up.

A sense of déjà vu of a journeyman arises spontaneously in everyone's hearts.

They began to wonder more about what Ren Yan had done before he became a teacher.

With the sound of grinding between the wood and the sawing bow, pieces of wooden planks of the same size were taken out by Ren Yan one by one.

In a short time, all the planks became useless materials.

Ren Yan immediately arranged the planks in a well grid shape and skillfully fixed them one by one with a claw hammer.

It didn't take long for a pad to be made.

Later, Ren Yan made a cylindrical shell with a movable opening on one side.

And in order to make it fit tightly together, a mortise and tenon joint structure is used.

The students on the side were amazed.

The skills of their own teachers are much better than theirs.

And netizens also gave birth to the feeling that even if Mr. Ren goes to do carpentry, he must be a good hand.

Look at this smooth action, it looks like it has been specially practiced.

Ren Yan didn't care about this, and after the shell was completed, he made another bracket.

The aluminium basin was placed on top of the stand and the charcoal was placed below, and all the gaps between the two layers were blocked, preventing the possibility of the charcoal coming into direct contact with the wood and causing a fire.

After that, both sides of the shell were also soaked with water, and a certain degree of fireproof treatment was done.

As long as there is no possibility of ignition in the first place, as long as the water vapor comes together, then this possibility is completely zero.

After placing a small section of wood that was about to be made into his own shape on the backing board, Ren Yan lit the charcoal and withdrew, while lowering the opening on the other side.

The work of fumigation began.

"That's it."

Ren Yan clapped his hands and crossed his waist:

"Normally, the wood fumigation time is 30 minutes, and we just have to wait during this time."

With that, Ren Yan was ready to go back to the chair and spread it out again.

But Wang Bo grabbed Ren Yan, pointed to the small ball of the bun head above and asked curiously:

"Teacher Ren, what is that thing for? You didn't say that~"

"Oh, that thing..."

Ren Yan raised his head and glanced at it, and the small ball, which was originally honest, began to shake up and down, and at the same time, a small piece of wood kept moving up and down.

"It's a temperature control device, the same as the speed limiting device on a steam engine."

"Let the energy in the cabin reach a constant state."

"The optimal temperature for fumigation is 56 degrees, and if we don't think about interference, the temperature of water vapor will soar to 100 per minute."

"If you are not careful at this temperature, you can completely waste the wood."

"So we have to put some limits on it."

"In the industry, people have a special temperature control device, which can accurately control to 56 degrees."

"We don't have this condition now, just just mean it, anyway, it's not much different, if it's not perfect in adjusting the time."

"If you find it inconvenient later, you can find a way to connect it to the thermometer."

"It's more troublesome, but it's better to be stable."

When the words fell, the students looked at Ren Yan in surprise, unable to say a word for a long time.

They don't understand, why a teacher who seems to be very attentive on the whole would be lazy and stealing like this in a certain way?

Is it really because it's not that important?

Or is your teacher really the kind of master who can fish in all aspects?

At this moment, they suddenly felt that they couldn't understand Ren Yan again.

Not only them, but even netizens and judges were completely overwhelmed.

How long will this guy be able to be serious wholeheartedly?

Then, the next moment, they heard a word that shattered their three views.

Ren Yan looked at the stunned appearance of his students, directly moved the chair over, sat on it with his ass, and hated that iron could not become steel:

"What kind of eyes are you looking at? Is there a problem with me? ”

"Don't you know that lazy people change the world?!"

"Use your little brains to think, when did the technological growth of human beings not be based on wanting to be lazy?"

"Not wanting to walk on their legs, people invented cars."

"Not wanting to be busy with a job all day, people invented semi-automated factories."

"Even the steam engine that triggered the Industrial Revolution was because Watt was too lazy to be tied to one place all day~"

"Laziness is the normal state of human beings, and formally because they want to be lazy, people will continue to use their brains to think of various tools to replace human beings."

"Even now some people don't want to drive, so they get driverless!"

"Once this technology is overcome, you think about it, is our technology going to the next level?"

"So, it's not a shame to be lazy~"

"It's a shame not to think of ways to be lazy."

"I don't want to stay at the fumigation equipment all the time, so I made a small device, and this device can achieve the effect of the demonstration."

"So, do you think I'm lazy now?"

At one point, Ren Yan was speechless for all the students of Class 9, including netizens and judges.

The other party's natural and crazy explanation can be regarded as deeply engraved into their hearts.

Aren't you just trying to make excuses for yourself?

Do you use so many miscellaneous things?

What did our sister say?

Why was the reaction so strong this time?

Class 9 felt a little bitter in his heart, but then they were a little entangled.

The meaning is like that.

But what my teacher said seems to make some sense...

And the more they think about it, the more relevant it becomes.

Aren't they too lazy to study orthodoxy, so they were led by their own teachers to make so many twists and turns?

Thinking about it like this, the students' expressions were completely tangled.

Instantly, I felt that my three views were being ruthlessly washed.

A thought called 'legitimate laziness' began to grow.

In the live broadcast room, netizens also recovered from the shock.

have brushed exclamation marks on the barrage:

“！

！

”

"Enlightened, master, I am enlightened! It turns out that I've never been lazy, I just want to change the world, why didn't I notice it before?! ”

"Is this the guidance of a famous teacher? A word to wake up the dreamer! ”

"This theory is amazing, while quibbling, it also promotes positive energy~"

"Understood, let's be lazy!"

"In terms of novelty of opinions, it has to be Teacher Ren, laughing to death."

"Lazy people change the world, absolutely!"

"Anyway, from today onwards, I will dedicate myself to the great rejuvenation of mankind, and I will be lazy every day!"

"Ren Yan: It's not shameful to be lazy, it's shameful not to think about how to be lazy (dog head)"

"Front, what are you talking nonsense to tell the truth!"

In the live broadcast room, there was a wave again.

In the broadcast room, the judges shook their heads with a wry smile.

Although this is true, they can't comment on it...

How so?

Let's just say that what Ren Yan said makes sense? Let's be lazy and use our brains together?

No matter how you listen to it, you feel that it is full of negative energy.

As a regular show, can they say such things?!

Naturally not!

But fortunately, the program team has practiced after all, and as soon as Ren Yan's rhetoric appeared, the director had already cut to the live broadcast of the other contestants.

Let a storm be extinguished.

However, soon, in the live broadcast room of other contestants, some netizens also began to talk.

One after another, the lazy man changed the world.

There are also various examples below.

For a moment, everyone was stunned for a moment.

A burst of laughter ensued.

Only the contestants in each live broadcast room, occasionally glanced at the barrage, and immediately fell into deep contemplation.

Why is it that in these years, everyone is so stylish?

Until the end, after they figured out that Ren Yan said this, they immediately changed to an expression that was more ugly than crying.

Hasn't this product stopped lately?

Why are you starting to make trouble again!?

You thought you wouldn't be playing with us anymore after you left school?!

Why are you starting again!

Is the ghost gone?!

However, they are not yet aware of it at this time.

Now it's just the beginning for them....
