Look at the clutter of planks in front of you.

The boys of Class 9 fell into deep contemplation.

Why did you come to this farm?

Why do you want to learn from your own homeroom teacher to build a thatched house?

Besides, you said you want to make it...

But why do you even want to reproduce this thing like furniture?

You say it's a reproduction, but why is there no nail?

A pile of discarded furniture, wooden planks are all there, but there is not a single nail, isn't this a bit outrageous?

Looking at the nail holes on those wooden boards, the boys in Class 9 always felt that someone was targeting them.

Is it Teacher Ren?

The students in Class 9 were a little skeptical.

But it doesn't always feel like it.

It's not that I believe in my teacher's character, but the main thing is that he doesn't have time to pull out all the nails of these furniture...

Just now, Ren Yan ran to the abandoned warehouse, and it only took five minutes to fill up...

Even if there are tools in five minutes, can Mr. Ren really remove all these nails?

It's unreasonable!

But who else could it be?

The original owner of this farm?

The furniture is thrown away, and there is no need to pull out the nails, this thing is worthless.

Even if you are thrifty, you are not so frugal...

The boys were a little confused.

The brows gradually squeezed into the Sichuan character...

"Don't think about what you don't have, let's think about how to get these pieces of furniture..."

"Otherwise, our thatched house will most likely be built for nothing."

"At the end of the day, it's too much of a stretch to get into a sleeping bag and sleep on the floor."

Xiao Yang's squad leader spoke out and withdrew everyone's thoughts.

The boys looked at each other and put the previous doubts in their hearts for the time being.

"The current situation is that we only have planks and no nails, is there any good way for everyone to make these things stand?" Wang Bo asked.

The crowd was silent.

Without nails, trying to get them to combine these planks is simply embarrassing for them!

After a few minutes of silence, though.

Li Qi suddenly patted his head and trotted two steps from the accommodation area to get the book that Ren Yan had thrown to them before.

"Detailed explanation of the structure of the mortise and tenon joint of the dragon country"

"Do you think this book can help us solve the furniture problem?"

"The previous teacher can say that the main application environment of the mortise and tenon structure is wood products."

Looking at the books in front of him, he listened to Li Qi's words.

The boys' eyes lit up.

"Makes sense!"

"Otherwise, there is no need for Teacher Ren to throw this book to us when he gets a thatched hut!"

"It can be seen that Teacher Ren is prepared in advance!"

"He must have known that there weren't enough nails."

"This is foreshadowing us in advance!"

At this moment, the boys felt that they had realized again.

Then he opened the book in a hurry and plunged into the sea of mortise and tenon structures.

It took about an hour to flip through it together.

The boys couldn't get enough of the books.

It has to be said that the ingenuity of the mortise and tenon structure is simply impressive.

With a little craftsmanship alone, the wood can be tightly combined.

And it can also be durable and removable.

It's the culmination of human ingenuity.

And this durability is not ordinary durability.

According to the book, most of the existing ancient wooden buildings in the Dragon Kingdom are completed with mortise and tenon structures, and there is not a single nail in the whole process, but they are standing on the land of the Dragon Kingdom for hundreds of years.

This is much longer lasting than some wooden products made with nails.

Although the boys of Class 9 only got a rough idea of it temporarily.

But they found it easy to usurp some furniture with the tenon and tenon structures in the book that had a clear method of making them.

And the tools they need are not difficult, nothing more than some saws, hammers, chisels and the like.

These things are currently available on the farm, and although they have rusted, they should still be usable, right?

After figuring out the joints, the boys began to look for the right tool in the pile of rusty tools.

But looking for it, Wang Bo suddenly paused, and his brows furrowed again.

After thinking for a moment, he slowly spoke:

"You say, is there such a possibility?"

"Actually, those nails were pried away by Teacher Ren in advance..."

"In order for us to learn the mortise and tenon structure spontaneously?"

"But Teacher Ren doesn't have time to do this..."Li Qi looked up and wondered.

"He just didn't have time to do it in front of us, but he arrived two days ahead of us..."Wang Bo said in a low voice.

At this moment, the students reacted instantly!

"Holy! I'll just say why this scene is familiar?! Co-authoring, this is still Teacher Ren's routine! ”

"No wonder I feel like I'm being led by something this day, it turns out that we were calculated by Teacher Ren!"

"This six!"

"Can't you teach us openly, why do you have to do so many routines?!"

"Where is the trust between people? Where is the harmony in our ninth class?! ”

The boys looked a little resentful.

Dissatisfaction with this abnormal feeling of being led by the nose.

They all turned around and glanced at Ren Yan viciously.

Ren Yan responded with a smile with a nail in his hand.

'Made, so it was! ’

The students' eyes went black in an instant.

"But the problem is..."

"If Teacher Ren really teaches us openly, will we learn seriously?"

At this time, Xiao Yang's squad leader made a gesture of smoking, and his expression was gloomy.

As soon as these words came out, the students were silent for a while.

the chicken, what you say makes sense!

Can you be a little more angry with the enemy?

We're all diss teachers!

You affect unity so much!

Immediately, they switched targets and glared at Xiao Yang's squad leader.

Xiao Yang's squad leader instantly shuddered: "That, I'll just tell the truth." ”

"Ah Wei..., you're right, don't say it again next time..."Li Cheng sighed and shook his head, patting the squad leader on the shoulder very sympathetically.

Immediately, he asked an even more fatal question.

"If Teacher Ren is really guiding us to learn one ring after another..."

"You say these tools, will they..."

Hearing this, the boys gasped.

Hurriedly picked up a rusty tool and began to work on the wood on the side.

Really...

If they guess so-so.

These tools have been completely obsolete.

The traces of rust were almost half a centimeter thick.

It doesn't work at all...

At this moment, the students' eyes went dark again, and they felt the deep malice from Ren Yan.

In the end, they had no choice but to grit their teeth and come to Ren Yan's side.

Squeezed out the voice word by word from between his teeth: "Teacher Ren, how to use those rusty tools, teach us!" ”

And Ren Yan clasped his ears with a smile, and probed in their direction by the way: "Ah, what did you say?" Louder, I can't hear clearly! ”

"Teacher Ren, teach us how to use those rusty tools!"

"Ah, you say..."

"Teacher Ren, you're almost done!"

The students couldn't take it anymore and roared angrily.

"Watch out for us and your blood splash five steps!"
