In addition to the splicing of the outer shell, the bigger problem comes from humidification and fire prevention.
Because the wood that needs to be fumigated is conservatively estimated to be at least three meters long, their fumigation equipment is made particularly large.
Soaking it all in water becomes a tedious task.
Moreover, a lot of charcoal is needed for fumigation, so the heat energy generated becomes stronger.
Ordinary soaking may not be effective at all, as it will be evaporated by charcoal in minutes, and the speed is much faster than the speed of water vapor generation.
They have done experiments on this.
After much deliberation, they decided that they could only choose to soak the wood before assembling the outer shell. Only in this way could they achieve the best fire-proof effect.
Or you can get a bunch of fire bricks out of there and use them to build the shell.
But this idea was extinguished by the students of Class 9 as soon as it came out.
It will take until next week for them to start making hundreds of fire bricks...
In addition to these, the most difficult part is the temperature control device.
It looks simple and the principle is not complicated.
It is just that the size of the steam in the cabin is used to drive the small ball on top to rotate on its own, and then the speed of rotation allows it to pull the connected wooden board to achieve a balanced effect.
But when they actually did it, they realized how difficult it was to achieve this process.
It took them a long time just to make a rotating ball.
Finally, after dismantling their teacher's control device, they were able to barely understand its structure and replicate it.
During this period, they wanted to listen to their teacher's suggestion and connect this thing to the thermometer.
For this purpose, they even bought several large thermometers.
But no matter how hard they racked their brains, they just couldn't achieve their goal.
Either the thermometer is broken and cannot be used.
Or they are connected on the surface, but in fact the two have nothing to do with each other.
In the end, they had no choice but to choose their teacher's method and leave everything to nature.
This also allowed them to fully appreciate the discrepancy between demonstration and actual operation.
No wonder many things look great during demonstrations, but fail when put to actual use.
The difficulty of the two is not even on the same order of magnitude.
Even when they were busy until mid-afternoon, they sincerely envied their own teachers.
When will they be able to be lazy and steal so calmly?
But fortunately, the efforts were not in vain.
They finished it all just as the sun was setting.
And couldn't wait to start his fumigation work.
Although it's time to go back to the apartment now.
But under everyone's efforts, Ren Yan could only meet their small request.
Looking at the sky which was getting dark, he suddenly felt like laughing.
I'm afraid these little guys don't know what they've missed...
Soon, the fumigation was completed.
The students of Class 9 were excited and took out one giant piece of wood after another with great anticipation.
However, when testing the quality of fumigation.
The face they were expecting suddenly became speechless.
This time they fumigated a total of ten pieces of wood.
But only three of them were truly fumigated properly.
The yield rate is frighteningly low.
This made them feel a little sad.
I have worked so hard, why did this happen?
It was only after a period of brainstorming that they confirmed that the problem was with the workmanship of the fumigation equipment and the texture of the wood itself.
This is exactly what my teacher said.
They need to keep experimenting.
Class 9 could only put this question behind them for the time being.
Start shaping the wood.
Just as Ren Yan had done, they placed aluminum basins one after another and began to shape them in sections.
But this thing is also different from the relaxed attitude shown by my teacher.
Until the moment they start shaping the wood, they don’t realize how difficult it is.
Don't use too much force, or you may damage the structure of the wood.
They want to destroy it!
But the texture of the wood simply doesn't allow them to do that!
No matter how hard you try, the wood will only bend so slowly and patiently.
And because there are too many sections, each person is responsible for a different area, so there will be some discrepancies.
After the overall plasticity was completed, the original wood already had some resemblance to the Golden Snake Sword.
The perfect arc that was expected was not achieved at all.
This made them even more tired.
I also deeply realized...
There is probably no way to do plastic surgery by yourself.
Finally, after a long sigh, they chose to give up temporarily.
Today I'll just use this as a practice session.
We will officially start making the keel tomorrow.
Just like that, everyone prepared to end their day's work in a sad mood and prepare to call their cheap teacher to go back to the dormitory together.
But when they turned their heads to look at the chair, they did not see Ren Yan, but only saw a note left on the chair.
【Stupid little bastards! 】
[If you want to work overtime, do it by yourselves. I, the teacher, will not accompany you. I will leave first. ]
【You guys can just go back by yourselves later. 】
[Oh, that’s right~]
[I have to remind you that the last bus in Qinhuang City is at 8pm.]
【Please remember not to miss it. 】
【Ren Yan.】
Look at the note and then look up at the sky.
A bad premonition suddenly came over the students of Class 9.
Without saying a word, they took out their phones to check the time.
【20:30】
In an instant, they felt as if something broke inside them.
This day is so fucking tragic!
Can we not build this ship?
Then, they could only look at classmate Wei with expectation.
Taking a taxi back to the apartment was the last option.
Walking five kilometers on foot is something they really can’t do now!
It is a double torture of body and mind!
In the end, Ah Wei could only nod slowly under everyone's gaze.
On this day, the students of Class 9 deeply realized what it means to work overtime and lose money...
