As soon as he finished speaking, everyone in Class 9 immediately turned their eyes:

“What method?”

“Print paint!”

"Paint?!!" Class 9 was stunned and said in disbelief: "You mean paint?!"

Wang Yu nodded:

"That's right."

"This is the only way to think about it."

"Painting not only prevents moisture, it can also form a protective layer on the periphery of the wood, so that barnacles cannot directly damage the wood."

"And now many marine paints have the effect of preventing barnacle parasitism, which is said to achieve their goal through odor."

"So we can actually give it a try."

"As long as the wood is dried, all problems will be solved."

Wang Yu said it very seriously, and it was obvious that it was thought about it.

But after hearing Wang Yu's explanation, the facial features of other students in Class 9 immediately squeezed together, looking constipated, and asked in confusion:

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

"Brother, we want to build ships of Ming Dynasty, not modern ships, so we have to use the methods of Ming Dynasty."

"You said this, it may work, but we can't use it."

For a moment, Class 9 fell into silence again.

Wang Yu frowned and nodded seriously:

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

"It seems that we can't handle this thing?"

"Ask him again?" Class 9 replied reluctantly:

"Now we are at the critical moment of the confrontation. If we lick our faces like this, will we seem cowardly?"

"Unless, you have a better way."

Wang Yu shrugged indifferently.

The others in Class 9 looked at each other in a glance, and finally they could only nod in silence:

"Just ask."

"How much money can face be worth?"

"In the end, Teacher Ren's victory will be the best."

"oh?"

"So you were just struggling with the problem of insect removal."

On the chair, Ren Yan looked at the bleak faceless Class 9 and others, happily saying:

"I thought you were still struggling with the keel."

"We did the keel matter this morning. Through the mortise and tenon structure, we can now withstand 300 kilograms of impact."

"From the time to continue to lengthen according to the current workmanship."

Awei responded honestly in his sigh.

Ren Yan nodded: "Yeah, it's not bad."

"It's been my expectation to get the keel completely done in about three days."

"Let's talk, what do you think you can't handle the worm removal?"

Immediately, Class 9 expressed their thoughts all the time, waiting for Ren Yan's answer in anticipation.

Ren Yan was shocked. After pondering for a few seconds, he spoke slowly:

"Did you say it or not? Haven't you already told the solution just now?"

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

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

Wang Bo spoke helplessly.

Ren Yan immediately gave the other party a blank look:

"Who told you that there was no paint in the Ming Dynasty?"

"Ha? Is there paint in the Ming Dynasty?"

Li Cheng spoke in surprise, Wang Bo also opened his eyes wide, and the others in Class 9 were shocked.

They have searched carefully for this, and they did not find any records of paint in the Ming Dynasty.

"It is not only in the Ming Dynasty, but also in the second century BC, there were records of using lacquer in the Long Kingdom."

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

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

"But things are the same principle."

"Mainly used on coatings."

"As for the paint in your mind, it was developed gradually in the 18th century due to the needs of industry."

"But even so, you can use it."

"I want you to imitate the Ming Dynasty, but it doesn't have to be in line with the Ming Dynasty."

"It's normal for hundreds of years to go out, and there are differences between them."

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

"Don't have such a dead mind. As long as the technology is the same, you can start your mind well."

After saying that, Ren Yan smiled and looked at his students happily.

Waiting for their exaggerated reaction.

However, this time, Ren Yan's expectations were willing to do so.

After listening to Ren Yan's explanation, Class 9 was also a little surprised and a little dumbfounded.

But more, it is a sense of decadence.

Most people have a silence on their faces.

Ren Yanheng couldn't figure it out, and after reading it over and over again several times, he could see a sentence in the expressions of the students in Class 9:

【Tired, destroy it.】

Ren Yan was stunned. After simple thinking, he decided to change the topic:

"Oh, forget it, I won't talk about this."

"Why don't we go to the beach in the afternoon to have fun!"
