After five years of teaching support, Daming became an empire on which the sun never sets.

Chapter 299 Manufacture of Steam Turbines

"Dili's daughter-in-law is right. Mr. came to Lujia Village to help us. There is not even a servant girl by his side... How can we endure loneliness when we are alone in the middle of the night? Even if we are on good terms with the eldest girl, everyone can understand."

It seems that those women who like to gossip have arranged a lot of things about me behind my back.Qin Yu sighed in his heart when he heard the words, but he was reasonable and considered very comprehensively.

"If you want to repay me in this way, then forget it." Qin Yu said.

"No!" Xiaoxiao said with a firm expression, "Xiaoxiao admires Mr.... In Xiaoxiao's eyes, Mr. is the most dazzling star in the vast galaxy. The love doesn't know where it started, and it goes deeper and deeper."

Looking straight at Qin Yu: "The concern in Mr. Pond's eyes that day is Xiaoxiao's peace of mind in this life."

"Han is vast, Jiang is eternal, how can it be as deep as my concubine's affection?"

She attends classes in school almost every day, and her level has improved rapidly.

"Xiaoxiao will leave after that, Xiaoxiao will not become any bondage to Mr.

Well, it's better not to go against the wishes of women.Qin Yu couldn't help but think of a poem: There are vines in the wild, and there are zero dews.There is a beautiful person, clear and graceful.Encounter, meet my wish.

Xiaoxiao has never touched a man before, and she trembles whenever she touches her body.

As soon as Jinfeng Yulu met, they won but countless on earth.

"Xiaoxiao finally knows what a real woman is today!" Xiaoxiao cried afterward, "Those women scolded me before for not despising even a dirty old man because of that. .”

Xiaoxiao feels like her body is going to melt: "Xiaoxiao feels that the past 20 years have been wasted."

At this time, neither of them noticed that outside his dormitory, a frail girl was standing swaying in the evening wind.She originally came to ask Qin Yu about raising rabbits, but she didn't expect to hear about the scientific experiment they did together during the day.

At noon the next day, Xiaoxiao came to Qin Yu's side again on the mountain ridge.

Among the flowers on the mountain ridge, Qin Yu taught her a lot of new knowledge. "Sir, you can do whatever you want Xiaoxiao to do."

……

Lujia Village Primary School.

"Today the teacher will teach you some practical things." Another week started, Qin Yu called all the students to the playground and said to the crowd.Xu Da watched silently from the side.

"You know the current situation of the village."

"It is really difficult to get in touch with the outside world."

"Therefore, we need to make reasonable adjustments to the teaching content of this elementary school. We can't just talk about book knowledge. We also need to teach students some practical things, which can be used in all aspects of life."

"Sir, what are you going to teach us today?" Zhu Xi asked, and the crowd had already guessed that today should be another practical class.

"Steam turbine!" Qin Yu said.

Steam turbine?The crowd was bewildered, they had never heard of this thing.

"The perfume workshops in our village are currently operated by hand. If this steam turbine can be used, the production efficiency will be greatly improved." Qin Yu said, "And when the villagers distill perfume, they will generate a lot of steam. wasted."

"And with the steam turbine, we can even build a steam locomotive to drive on the roads in the village."

"Sir, what is a steam turbine?" someone in the crowd asked.

"In fact, I should teach you the steam engine first, because the steam engine is the pioneer of the industrial revolution. However, the steam turbine is more efficient than the steam engine, and it is easier to build."

"Although the conditions in our Lujia Village are poor, I believe that as long as we give full play to our wisdom and hardworking and simple spirit, even the poor conditions can create miracles."

"Yellow label!"

"exist!"

"Go and boil a pot of water."

"Yes!"

Lujiacun Primary School does not have a dedicated kitchen, and the stove is open-air.

Although almost all villagers in the village have moved into new houses, Lujiacun Primary School has not yet been remodeled.

Because the elementary school is the ancestral hall of the Lu family.

The ancestral hall cannot be broken easily. Once the ground is broken, the ancestral tablet will be disturbed.Usually not rebuilt or renovated.

Therefore, Lujiacun Primary School is still very dilapidated, or ancient.

Qin Yu remembers seeing it in an economically developed southern city before, surrounded by dozens of high-rise buildings, but there are some low and ancient buildings hidden inside, which are the ancestral halls of the village community.

With the help of several other students, the water in the cauldron was soon filled, and the firewood in the stove was set up and blazing.

After a stick of incense, the water in the pot boiled.

White smoke came out, and the lid of the pot kept going up and down.

"Did you see the pot lid being pushed?" Qin Yu began to inspire the students' thinking.

"See, isn't this a very common thing?" Xu Miaojin said, "Basically every household has it. Every time the villagers cook, the heat in the pot can also push the lid of the pot."

"Steam can push the lid of the pot, so it can push other things." Qin Yu continued to inspire the crowd, "For example, using the power of steam and the principle of gears to create an automatic spinning machine."

"But sir, the steam can only push the lid of the pot, and the force is too small. I'm afraid it won't be of much use." Zhu Yingrao said, "I'm afraid it's impossible to use such a small force to push the spinning machine to spin."

"Well said!" Qin Yu applauded loudly.

"Sir, what did I say?" Zhu Yingrao was taken aback and asked suspiciously.

"Your words have revealed the fundamental reason why we Chinese ancients did not invent the steam engine first." Qin Yu said, "We Chinese ancients were able to invent gunpowder, improve papermaking, Sinan, and printing, which proves that they are still very wise. And Famous scientists Song Yingxing and Zhang Heng didn’t invent the steam engine, so why?”

"It's because they have the same thinking as you. They feel that the power of steam is too weak, so they don't think about how to use it."

"This is called a blind eye."

"Isn't the power of steam insignificant?" the crowd wondered.

"Xu Da!" Qin Yu called to the side.

"What's the matter, sir?" Xu Da came over and asked.

Deep in his heart, he also felt that steam might not be of much use.

"You are the strongest one among us. You press the lid of the pot hard to see how strong the steam is." Qin Yu said, "Remember, you only need to feel the strength of the steam. If you can't hold it down, don't force it. So as not to fry the pan."

"Okay, I'll give it a try." Xu Da thought to himself, what a joke, I'm a majestic seven-time man, and I can't even deal with steam?

After speaking, he walked over and directly pressed the lid of the pot.

"Let's back off." Qin Yu said immediately upon seeing this.Stand ten meters away with the students.
