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

Of course not!

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

Let a storm die down.

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

The rhetoric that lazy people change the world appeared one after another.

And various examples are given below.

For a moment, everyone was stunned for a moment.

Then there was a burst of laughter.

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

Why is everyone acting so stylish these days?

Until the end, after they figured out that Ren Yan said this, they immediately put on an expression that was uglier than crying.

Isn't this stuff pretty quiet lately?

Why did you start messing around again! ?

Thought you stopped playing with us after you left school? !

Why are you starting again now!

Is the ghost lingering? !

However, they didn't realize it at this time.

For them, it's just the beginning....

Chapter 267 Working Overtime Lost Money!

Time passed by minute by minute.

Naturally, Ren Yan didn't expect what kind of storm her words would bring about.

After waiting three 10 minutes.

Ren Yan slowly opened her eyes and started the next work.

He wandered over to the earthen fumigator and opened the side door.

In an instant, a large amount of steam gushed out.

After the steam dissipated completely, Ren Yan came to the side of the wood in two steps, and slightly touched it with his fingers.

Now the touch of wood is very different from before, it is no longer as hard as before, but a bit soft.

Seeing this, Ren Yan nodded.

Take out the wood directly, and extinguish the charcoal that is about to burn clean by the way.

Then put the wood on top of the aluminum basin prepared before, and put some bricks on the corners and turn it upside down.

Under the aluminum basin, some lit charcoal was still placed.

After finishing all this, Ren Yan looked at the students in Class Nine:

"The wood is so fumigated that the softness inside can be clearly felt, and the color is slightly darker."

"Afterwards, the wood needs to be plasticized by heating."

"The fumigated wood alone is not enough to complete the shape, the temperature must be maintained to a certain point."

"The plasticity of each wood is different, you can search or experiment later on."

"And in the process of shaping, you must be patient and complete step by step. Don't use too much force. Otherwise, all you can get is a piece of wood with a lot of cracks inside."

"This kind of wood, if you are not careful, it will be light when it falls apart."

While speaking, Ren Yan slightly bent the piece of wood in front of her with her own hands.

The expression is extremely serious, and the speed of bending is also extremely slow.

If it wasn't for a long time of staring, there wouldn't even be any traces of Ren Yan's hands moving with the wood.

But it is in this slowness that the wood gradually deforms.

After about 10 minutes, a kind of arc that is too exaggerated to appear on the wood is completed.

Ren Yan took a look at the crescent-shaped piece of wood, and nodded in satisfaction:

"This is the curved wood you want. With this kind of curved blessing, there should be no problem in making a suitable keel."

"As for the rest, it is natural air-drying and the application of tenon and tenon structure."

"I've said all these before, and you have actually operated them, so I won't say more."

"You just need to know that the wood has to be air-dried until the color is restored to [-]-[-]%, and it has a perfect wooden feel to the touch."

"Otherwise it won't fit perfectly with other woods."

After finishing speaking, Ren Yan threw the wood in her hand to the students of class nine, and walked towards the chair again on her own.

This time, thanks to the fact that the wood chosen by Ren Yan is not big, if it is huge, the time it takes may still be super doubled.

After receiving the wood thrown by Ren Yan, the whole class of Class [-] observed it carefully, and kept recalling what Ren Yan had just done.

After a while, they feel that they have mastered this skill.

Started to prepare to make some new fumigation devices.

With the existence of this kind of technology, are they still afraid that they can't handle the keel?

Therefore, they acted quickly.

Only Wang Yu felt that things might not be so simple.

Before the action, I asked my classmates to tell me how to play tenon and tenon.

He felt that only in this way could he consider himself more perfect.

However, the answer was:

"It's not clear to you now, you have to practice this stuff."

"Do you understand practice? It's your favorite kind of thing!"

Regarding this, Wang Yu was speechless, and could only act together with the students of Class Nine in desperation.

However, the uneasiness in his heart became more and more intense.

Is it really that simple to build a giant keel?

......

Over time.

It was only when night fell that Class Nine had completed all the fumigation devices.

In the fenced area around the warehouse, earth-made fumigation equipment has been erected one after another, large and small.

And during the manufacturing process, they discovered just how flawed this method is.

The fumigation wood my teacher chose was only [-] to [-] centimeters short, so the equipment used was naturally too small.

You can build it with your hands, just like building blocks.

But once the volume of this 'building block' has leapfrogged, the difficulty is not at the same level at all.

Any problem that is so small that it can be ignored will be infinitely magnified.

Just the assembly of a shell alone took a lot of their time.

Let them be forced to review the mortise and tenon structure, although it is still the simplest connection method.

But after such an afternoon of nurturing, they felt that the previous feeling had returned, and even surpassed it.

It was also during this process that Wang Yu understood the practical application of mortise and tenon joints.

And in the whole afternoon, I used some small carpenter's tools to compete with the mortise and tenon, but I still couldn't make a perfect mortise and tenon.

The spliced ​​outlines are always wobbly, and the analysis between them is also looming with this wobbling, but they just don’t collapse.

It's really the same as a figure with poor workmanship.

It made him extremely tired.

Be it said or not, Mr. Ren's metaphor is always so apt.

In addition to the splicing of the shell, the bigger problem comes from the humidification and fire prevention.

Because the wood that needs to be fumigated is conservatively estimated to start at three meters, their fumigation equipment is made extra large.

Wetting it all with water becomes a very tedious task.

Moreover, extra charcoal is needed for fumigation inside, so the heat energy generated becomes thicker and thicker.

Ordinary soaking may not be effective at all, and it will be evaporated by charcoal in minutes, which is much faster than the speed of water vapor generation.

This point, they have done experiments.

After thinking about it, they can only choose to soak the wood before splicing the shell, only in this way can the best fire prevention effect be achieved.

Or recreate a bunch of fire bricks and use fire bricks to build the shell.

But this idea was stifled by the students of Class Nine as soon as it was born.

Hundreds of thousands of fire-resistant bricks are produced, and I am afraid that they will not be able to start until next week...

And besides these, the most difficult point is the temperature control device.

It looks very simple, and the principle is not complicated.

Just use the size of the steam in the cabin to move the small ball on the top to rotate by itself, and then use the speed of rotation to make it pull the connected wooden boards by itself to achieve a balanced effect.

But when they really do it, they know how difficult it is to achieve this process.

It took a long time for them to spin the ball alone.

Finally, after dismantling the control device of their teacher, they barely understood its structure and reproduced it.

During this period, they wanted to listen to their teacher's suggestion to connect this thing with a thermometer.

For this reason, they also specially bought several large thermometers.

But no matter how hard they racked their brains afterwards, they just couldn't achieve their goals.

Either the thermometer is broken and unusable.

Either it is connected on the surface, but in fact the two have nothing to do with each other.

In the end, they could only choose the method of their own teachers and leave everything to nature.

This also allowed them to fully appreciate the difference between demonstration and actual operation.

It's no wonder that many things are fine during the demonstration, but when it comes to actual operation, they praise it.

The difficulty of the two is not in the same order of magnitude at all.

Even when they were busy till mid-afternoon, they sincerely envied their teacher.

When can they be so lazy and calm?

But fortunately, the hard work was not in vain.

They did it all by the time the sun went down.

And couldn't wait to start my own fumigation work.

Now it's time to go back to the apartment.

But under everyone's efforts, Ren Yan could only meet their small request.

Looking at the darkened sky, he suddenly wanted to laugh.

The cubs in front of me are afraid that they don't know what they missed...

Soon, the fumigation is complete.

The students in Class Nine were elated and looked forward to taking out giant logs one after another.
