There are doubts, regrets, and at the same time a little bit of expectation.
I hope Class 9 can solve all the problems.
Time passed again.
About ten minutes later.
Wang Yu frowned and asked tentatively:
"In fact, there may be a way to solve both problems at the same time."
As soon as the voice fell, everyone in Class 9 immediately turned their eyes over:
"What method?"
“Paint it!”
“Paint?!
"Class 9 was stunned and asked in disbelief: "You mean paint?!"
Wang Yu nodded:
"That's right."
"After much thought, this method is the most effective."
"The paint not only repels moisture, but it also forms a protective layer around the wood, which prevents barnacles from directly damaging the wood."
"And now many marine paints have the effect of preventing barnacle parasitism, and it is said that this effect is achieved through smell."
“So we can actually give it a try.”
"When the time comes, as long as the wood is properly dried, all problems will be solved."
Wang Yu spoke very seriously, and it was obvious that he had thought it over.
But after listening to Wang Yu's explanation, the other students in Class 9 immediately huddled together, looking constipated, and asked in confusion:
"But the problem is, he must have had paint in the Ming Dynasty..."
"Brother, we are going to build a ship according to Ming Dynasty specifications, not a modern ship. We have to use Ming Dynasty methods."
"You said this, it might 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 may have to ask Teacher Ren..."
"It seems like this thing is not something we can handle?"
"Ask him again?" Team 9 replied reluctantly:
"We are at a critical moment in the battle now. If you ask us in such a servile manner, won't it make us look like cowards..."
"Unless you have a better way."
Wang Yu shrugged indifferently.
The other members of Class 9 looked at each other, and finally nodded silently:
"Just ask..."
"How much is face worth?"
"In the end, it was still Mr. Ren who won..."
......
"oh?"
"So you were just worrying about pest control."
Sitting on the chair, Ren Yan looked at the bleak-looking Class 9 and others with great interest, and said cheerfully:
"I thought you were still struggling with the keel."
"We have already finished the keel this morning. With the mortise and tenon structure, it is now conservatively estimated to be able to withstand an impact force of 300 kilograms."
"After that, we just need to continue to lengthen it according to the current workmanship."
Classmate Awei responded obediently with a sigh.
Ren Yan nodded: "Yeah, not bad."
"It took about three days to completely fix the keel, which has met my expectations."
"Tell me, what do you think is the problem with pest control?"
Then, Class 9 told Ren Yan everything they had just thought about, and waited expectantly for Ren Yan's answer.
Ren Yan clicked his tongue, and after a few seconds of silence, he slowly spoke:
"Didn't you guys just tell me 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 spoke helplessly.
Ren Yan immediately rolled his eyes at the other person:
"Who told you there was no paint in the Ming Dynasty?"
"Huh? Was there paint in the Ming Dynasty?"
Li Cheng exclaimed in surprise, Wang Bo also opened his eyes wide, and the other people in Class 9 all looked horrified.
They have done a thorough search on this and indeed found no records of paint being found in the Ming Dynasty.
"Not only in the Ming Dynasty, as early as the second century BC, there are records of the use of lacquer in the Dragon Kingdom."
"It was already mature by the Ming Dynasty, okay?"
“Although it was called lacquer art at that time, it was not paint.”
“But it’s all the same principle.”
“It’s mainly used for coating.”
"As for the paint in your mind, it was probably gradually developed in the 18th century due to industrial needs."
"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."
"There is a difference of several hundred years between the two, so it is normal to have some discrepancies."
“Now that there are better materials, why not use them?”
"Don't be so stubborn. As long as the craftsmanship is the same, you can use your brains."
After saying that, Ren Yan smiled and looked at her students happily.
Waiting for their exaggerated reaction.
However, this time, Ren Yan's wish was not fulfilled.
After listening to Ren Yan's explanation, Class 9 was somewhat surprised and speechless.
But more of it is a sense of decadence.
There was a sense of silence on the expressions on most people's faces.
Ren Yan couldn't figure it out anyway. After reading it over and over again, he finally saw a sentence in the expressions of the students in Class 9:
【Tired, destroy it...】
Ren Yan was stunned. After a brief thought, he decided to change the topic:
"Oh, forget it, let's not talk about this anymore."
"Why don't we go to the beach and have some fun this afternoon?"
