Live broadcast: Teach students to play Three Kingdoms at the beginning

"Once the wood is damp, it is easy to breed pests."

As soon as this remark came out, the students in class nine were stunned for a moment.

They stared blankly at the administrator, their eyes were full of blankness, and even their expressions became a little dull.

Yes
How to solve the problem of pests!
Damn, never thought about it at all!

How can there be so many things with a keel? !
Can you still have fun!

Immediately, their expressions became tangled, and many students looked at the administrator.

There was a hint of confusion, a hint of pleading, and a hint of anger in his eyes.

You said you are fine, why remind us? !

Shall we get excited for a while? !

But the administrator didn't pay much attention to it. He just saw the plea and knew what the students in front of him meant.

This is to hit the idea on himself!
He spread his hands helplessly:

"As you know, I'm just an auto parts maker."

"It's not easy to find the problem."

"I'm afraid it's a little difficult for me to solve it."

"In the words of your young men."

"It's just that you may have misunderstood Uncle Chang and me."

The students in class nine watched him silently, and it took a long time before he sighed, and the tone became sad:
"Then you don't need to speak out so bluntly, it makes us very distressed."

"In such an old society, has no one told you that it is better not to ask a question than to ask a question without a solution?"

"It's easy to get fired if you go to work like this."

"That's why I came here to make auto parts myself~"

The administrator answered naturally.

The students in class nine were startled for a moment.

Damn, why are these adults so impeccable in some aspects?

Is this an adult who has been beaten by society?
Three hundred and sixty degrees in all directions without dead ends? !

After everyone struggled for a while, seeing that the administrator really had no choice but to drag the ashes of the completely completed dragon back to his warehouse.

The originally excited mood was completely extinguished.

Everyone looked extremely tired.

Blowing my liver for several days, the result is only to solve a small problem on a widget?

Shipbuilding is too difficult!

For a while, many people even had the slightest thought of giving up.

I grew up so big, when did I suffer from this crime!

But after thinking about the experience of the past few days, they felt that it was a loss to give up suddenly.

If you really just give up like this, wouldn't it mean that you have been blind for a few days?

At that time, if the cheap teachers at home are not in order, they will have to laugh at themselves.

【Hey, look, I wasted more than half a month for nothing~】

【The result is nothing~】

[Spicy chicken! 】

Thinking of this possibility, and looking at Ren Yan who was still lying dead on the chair, they immediately put this thought out of their minds.

Isn't it just a matter of deworming?
Done!

It's all over now, whoever gives up is a dog!

At this time, they do not know that there is a word called the cost of silence.

They have paid too much for this matter.
...

After returning to the warehouse, Class Nine formed a circle again and began to discuss the issue of deworming.

The atmosphere is more or less depressing.

Ren Yan glanced at them, feeling a little puzzled in her heart.

Is this Keel failing again?

The whole scene is so big, and this is the result?

At this moment, Ren Yan even wanted to take the initiative to help them.

Time passed minute by minute.

An hour passed in a blink of an eye.

During this hour, the students in class nine came up with various methods, and they also checked a lot on a certain degree.

What drying, medicine, frequent maintenance.

Physical and chemical ideas have been mentioned by them a lot.

But there is always something missing.

The most important point of this is that, as the keel of a ship, it is destined to be damp.

Once the wood is damp, no matter how complicated the treatment is, insects are almost inevitable and almost unavoidable.

This is the ecology of nature and cannot be reversed.

And there is another point that Class Nine did not expect.

That is when they thought about the problem of deworming, they thought of another problem.

Marine parasites, things like barnacles.

Barnacles can easily cover the current steel giant ship, let alone a wooden ship.

Infestation by barnacles is a [-]% problem.

So how about thinking about it this way?

Class Nine discovered that they had dug another big hole for themselves.

Insect prevention, they think they can still find a way to solve it.

But what about the damage to wood by barnacles?
You can't find someone to go to the sea to clean up all the time, right?

I never heard that it would be so cumbersome to set up a long-distance voyage in ancient times.
The atmosphere fell into a stalemate for a while, and everyone in Class Nine looked sad.

Even netizens who don't think it's a big deal to watch the excitement feel that this "subject" is too big.

Originally, they thought it was just building a ship. Although it was difficult, it should still be within the controllable range.

But as Class Nine got deeper, they also realized the difficulties more and more.

'Is this thing really something that a group of high school students can handle? '

This question came to their minds again.

There are doubts, regrets, and at the same time, a little bit of expectation.

I look forward to Class Nine being able to solve all the problems.

Time passed again.

After about 10 minutes passed.

Wang Yu frowned tentatively:
"Actually, there may be a way to solve both problems at the same time."

As soon as the words fell, everyone in Class Nine immediately turned their eyes over:
"what way?"

"Paint!"

"Paint?!

Class [-] was taken aback, and said in disbelief, "You mean paint?" ! "

Wang Yu nodded:

"Yes."

"After much deliberation, only this method is the most effective."

"The paint not only repels moisture, but also forms a protective layer around the wood so that the barnacles cannot directly damage the wood."

"Moreover, many marine paints now have the effect of preventing parasitic barnacles. It is said that the purpose is achieved through smell."

"So we could actually give it a try."

"At that time, as long as the wood is dried, all problems will be solved."

...

What Wang Yu said was very serious, and it could be seen that he had thought about it.

But after listening to Wang Yu's explanation, the other students in Class Nine immediately huddled together, looking constipated, and asked quite puzzled:

"But the problem is, he also had to have paint in the Ming Dynasty."

"Brother, we want to build a Ming Dynasty ship, not a modern ship. We have to use the Ming Dynasty method."

"You say this, it might work, but we can't use it."

For a while, Class Nine fell into silence again.

Wang Yu frowned and nodded seriously:

"Then I think we might have to ask Teacher Ren."

"It doesn't seem like we can handle this thing?"

"Ask him again?" Class Nine replied reluctantly:
"Now we are at a critical moment of confrontation, so if we lick our faces and ask, will it appear that we are cowardly?"

"Unless you have a better way."

Wang Yu shrugged indifferently.

The rest of Class Nine looked at each other, and finally they could only silently nod:

"Just ask."

"How much is face worth?"

"In the end, it's Teacher Ren's complete victory."

"Oh?"

"It turns out that you were struggling with the problem of deworming just now."

On the chair, Ren Yan looked at the bleak-faced class [-] and others with great interest, and said cheerfully:
"I thought you were still struggling with the keel."

"We took care of the keel this morning. Through the mortise and tenon structure, it is now conservatively estimated that it can withstand an impact of [-] kilograms."

"After that, just continue to lengthen according to the current workmanship."

Classmate Ah Wei replied honestly while sighing.

Ren Yan nodded: "Well, not bad."

"It took about three days to completely fix the keel, which has met my expectations."

"Tell me, what do you think can't be done in terms of deworming?"

Immediately, Class Nine articulated their thoughts just now, and waited expectantly for Ren Yan's answer.

Ren Yan was stunned, and after pondering for a few seconds, she slowly spoke:
"Did you say it, didn't you just say the solution?"

"The painting method mentioned by Wang Yu is very good, why not use it?"

"But the problem is, there was no paint in the Ming Dynasty."

Wang Bo said helplessly.

Ren Yan immediately rolled her eyes at the other party:
"Who told you that there was no paint in the Ming Dynasty?"

"Huh? Was there paint in the Ming Dynasty?"

Li Cheng made a sound in surprise, Wang Bo also opened his eyes wide, and the rest of Class Nine showed shock.

They have searched carefully for this point, and indeed there is no record of paint found in the Ming Dynasty.

"Not only in the Ming Dynasty, but as early as the second century BC, there were already records of using lacquer in the Dragon Kingdom."

"By the Ming Dynasty, it was already very mature, okay?"

"Although it was called lacquer art at that time, it was not paint."

"But everything works on the same principle."

"Mainly used on top of the coating."

"As for the paint in your mind, it was probably developed gradually in the eighteenth century because of the needs of industry."

"But even so, you can still use it."

"I want you to imitate the Ming Dynasty, but it doesn't have to be exactly the same as the Ming Dynasty."

"The difference between the two has been hundreds of years, and it is normal to have discrepancies."

"Now that there are better materials, why not use them?"

"Don't be so brainy, as long as the craftsmanship is the same, you can use your brains well."

After all, Ren Yan smiled and looked at her students happily.

Waiting for their exaggerated reaction.

However, this time, Ren Yan's expectations were fulfilled.

After listening to Ren Yan's explanation, although Class Nine was a little surprised, he was a little dumbfounded.

But more, it is a sense of decadence.

There was such a silence in the expressions on most people's faces.

Ren Yan couldn't figure it out anyway, after reading it over and over several times, he finally saw a sentence in the expressions of the students in Class Nine:

【Tired, destroy it.】

Ren Yan was taken aback, and after a brief thought, he decided to change the topic:
"Oh, forget it, let's not talk about this."

"Why don't we go to the beach in the afternoon and have a good time!"
