Luo Xuan wandered into the side hall next door, spread out paper and pen on the desk in front of the statues of the four heavenly kings, and concentrated on drawing.

I don't know how long it took.

Just as Luo Xuan was carefully recalling the structure of threshing machines of later generations, he also took a look at the design of the sewing machine pedal.

The sewing machine, pedals and pedals are the structure of a drum machine, which is not complicated.

But what material should be used as the transmission belt?

Such a small problem still stumped Luo Xuan.

Because during this period, rubber was a strategic material and was strictly controlled, making it inaccessible to ordinary people.

Moreover, the quantity of a belt with special specifications is too small, so no unit will accept the order and tailor it for itself.

Since rubber doesn’t work, what should we use instead?

It's definitely not possible to use hemp rope.

Hemp rope is not wear-resistant and will swell due to moisture.

It's okay to use an iron chain, just like making an iron chain similar to a bicycle chain.

But in that case, the amount of steel used in a threshing machine will exceed the standard even more.

It will also increase the overall weight of the threshing machine, and if it is driven by an iron chain, the iron chain will easily rust in the future.

Just as Luo Xuan was lying there, thinking carefully about what material should be used to make the transmission belt.

"Infinite Life Buddha."

The familiar voice of Huayang Taoist came from behind: "This fellow Taoist, it's the first day of school today, why did you skip school? How can you be a good person with both good character and academic performance when you are so lazy?

student?"

Luo Xuan replied without raising his head: "Being behind closed doors is a deep mountain, and you can study in a pure land anywhere. Old Niubi, you just knock on your chime and recite your scriptures. What does it have to do with me, a common man, doing common things?"

Old Taoist Huayang snorted coldly, "You kid is so clueless! Taoist, I kindly remind you, kid, why are you so rude?"

Luo Xuan bit his pencil, thinking about the problem of the transmission belt, and replied calmly: "Did you eat not salty enough for lunch?"

Old Taoist Huayang laughed angrily: "You are also a child from the production team. It is not easy for you to study at home. Old Taoist, I just want to remind you out of kindness, how can you blame me for meddling in other people's business?"

Luo Xuan said: "If there are no underachieving students like me, how can we highlight the excellence of those advanced students?

Just like what you Taoists say, there are mountains facing the sun and shadows facing away, and heaven and earth have yin and yang.

I am like a weed growing in the shade. As long as my heart is toward the light and grows toward the sunny place, then you can't say that I am not a good weed, right?"

"You are the only one who talks a lot of lies!"

Mr. Huayang's eyes widened, "If you waste your years and miss your studies, you won't have time to regret it later. Do you plan to live in a small ravine and be a farmer for the rest of your life?"

Luo Xuan pouted, "How come you still look down on the vast number of production team members? Without their hard work, how could you make clothes without weaving, and eat without tilling?"

As soon as he said this, Luo Xuan felt that he might have said it a bit too harshly.

Then he softened his tone and said to Hua Yang, "O master, everything is of inferior quality, except for the days of high-level education, which has long passed."

Luo Xuan said slowly, "Do you believe that as a 'student with special talents', I can still get a diploma and successfully enter middle school?"

"Bragging!"

Huayang Lao Taoist dismissed Luo Xuan's words, "If you have a big butt, what special skills can you have?"

When Luo Xuan heard the word "bragging cowhide", his heart suddenly moved: If you can't get rubber, you can get cowhide rope!

Just weave a few thin strands of cowhide together and it's done, right?

"Hahaha--"

Luo Xuan, whose thoughts suddenly became clear, couldn't help but laugh happily, "I didn't realize that you, such an awesome veteran, besides being verbose and fighting for meat with me, actually have some uses!"

As he said that, Luo Xuan didn't care about the old Taoist Huayang who was stunned in place, his chest aching because of his anger.
