"The daughter-in-law said well, Mr. came to Lujia Village to help us, and there was not even a maid by his side...... How can a person endure loneliness in the middle of the night? Even if you're on good terms with a big girl, everyone can understand it."

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

"If you're trying to repay me in this way, forget it." Qin Yu said.

"No!" Xiaoxiao said with a firm expression, "Xiaoxiao respects Mr. ...... In Xiaoxiao's eyes, Mr. is the most dazzling star in the vast galaxy. I don't know what to do, and I go deep."

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

"The breadth of the Han and the eternity of the river, how can the concubine's affection be as deep as that?"

She attends classes in school almost every day, and her level improves quickly.

"Xiaoxiao will leave after that, Xiaoxiao will not be any shackle to Mr."

Well, it's better not to go against the woman's wishes. Qin Yu couldn't help but think of a poem: There are vines and grass in the wild, and there is no dew. There is a beautiful person, clear and graceful. Encounters and encounters are suitable for my wishes.

Xiaoxiao had never touched a man, and she trembled when she touched her body.

As soon as the golden wind and jade dew meet, they will win countless in the world.

"Xiaoxiao finally knows today, what is a real woman!" After that, Xiaoxiao cried, "Those women scolded me before for not even disliking a dirty old man for that, I thought it was incredible at the time, and now I understand."

Xiaoxiao felt that her body was about to melt: "Xiaoxiao feels that the previous twenty years have been in vain."

At this time, neither of them noticed that outside his dormitory, a weak girl stood in the evening breeze. She originally came to ask Qin Yu about the cultivation of rabbits, but she didn't expect to hear about the scientific experiments they did together during the day.

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

Among the flowers on the mountain beam, Qin Yu taught her a lot of new knowledge. "Sir can let Xiaoxiao do whatever he wants."

……

Lujiacun Primary School.

"Today the teacher is going to teach you something practical." Another week began, Qin Yu called all the students to the playground and said to the crowd. Xu Da watched silently from the sidelines.

"You know the current state of the village."

"It's really hard to get in touch with the outside world."

"Therefore, the teaching content of this primary school needs to be reasonably adjusted, and it is not just about book knowledge. I also need to teach you some practical things to use in all aspects of life."

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

"Steam turbines!" Qin Yu said.

Steam turbines? The crowd was confused, they had never heard of this thing before.

"The perfume workshop in our village is currently operated by hand, and if we can use this steam turbine, the production efficiency will be greatly improved." Qin Yu said, "And when the villagers distill the perfume, a lot of steam will be generated, and it will be wasted if it is not needed."

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

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

"Actually, as a teacher, you should have taught you the steam engine first, because the steam engine was the forerunner of the industrial revolution. But steam turbines are more efficient and easier to build than steam engines."

"Although the conditions in our Lujia Village are simple, we believe that as long as we give full play to our wisdom and hard-working and simple spirit. Even the most humble conditions can work miracles."

"Yellow Label!"

"Yes!"

"You go boil a pot of boiling water."

"Yes!"

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

Although almost all the villagers in the village lived

The new house has not been renovated, but the Lujiacun Primary School has not been renovated.

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

The ancestral hall cannot be easily grounded, and once the ground is broken, the ancestral tablet will be alarmed. It is generally not rebuilt or renovated.

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

Qin Yu remembered that he had seen it in the economically developed southern cities before, and there were already dozens of high-rise buildings around it, but there were some low and ancient buildings hidden inside, which were the ancestral halls of the village community.

With the help of several other students, the cauldron was soon filled with water, and the firewood in the stove was erected and burning.

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

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

"See the lid being pushed?" Qin Yu began to inspire the students' thinking.

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

"If the steam pushes the lid, it pushes 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 this force is too small, I'm afraid it's not of much use." Zhu Yingrao said, "If you want to use such a small power to push the spinning machine to spin, I'm afraid it's impossible."

"Well said!" Qin Yu applauded loudly.

"Sir, where did I speak?" Zhu Yingrao was taken aback and asked suspiciously.

"Your words speak to the fundamental reason why our ancient Chinese people did not invent the steam engine first." Qin Yu said, "Our ancient Chinese people were able to invent gunpowder, improve papermaking, Sinan, and printing, which proved to be very wise. There are also famous scientists Song Yingxing and Zhang Heng, none of them invented the steam engine, why on earth?"

"It's because they think the same as you, and they feel that the power of the vapor is too small, so they don't think about how to use it."

"It's called a blind eye."

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

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

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

In his heart, he also felt that the steam thing was probably of little use.

"You're the strongest of us, you hold down the lid hard to see if the steam is too strong." Qin Yu said, "Remember that you only need to feel the power of the steam, and if you can't press it, don't force it, so as not to fry the pan."

"Okay, I'll try." Xu Da secretly thought in his heart, joke, I'm a seven-time man, and I can't even deal with a steam?

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

"Let's stand back." Seeing this, Qin Yu immediately said. I stood ten meters away with the students.
