We have fought to the Arctic Circle, and you want me to inherit the throne?

This first class lasted three hours.

What Li Che was facing was not an ignorant junior high school student, but a top talent dug out from the Ministry of Works, a master craftsman of the time.

Some questions do not require much explanation, and everyone will understand with just a little guidance.

Li Che spoke directly from [Chapter 1, Description of Movement] to [Chapter 3, Interaction - Force]. He was so thirsty that his mouth was dry, but everyone was getting more and more excited.

Even old man Qian Bin had a flushed face and no sign of fatigue on his face.

The crowd was like a long-dry field that welcomed a downpour, greedily absorbing every drop of moisture.

After the baptism of physics, various professional problems that had previously troubled them were suddenly solved.

But Li Che really couldn't bear it anymore. There was no such high-intensity teaching during the final sprint of his senior year.

After finishing Chapter 3, Section 4 [Composition and Decomposition of Forces], he immediately closed the textbook and said in a hoarse voice:

"That's all for today. I'll tell you the rest tomorrow."

Li Che waved his hand weakly, and Qiu Bai quickly handed him a cup of tea.

Everyone woke up as if from a dream, looked at the sky outside, and found that half a day had passed without them realizing it.

At this moment, everyone's expressions were complicated.

What Li Che talks about are all knowledge from junior high school physics textbooks. They are the basics of the basics and are simple and easy to understand.

It is precisely because of this that everyone was surprised to find that this "physics" was not as unorthodox as they had imagined.

On the contrary, its logic is rigorous and self-consistent.

Almost all knowledge points can overlap with real-life experience, and there is no need to question their rationality.

Everyone seemed to see a door to a new world slowly opening to them.

Li Che took a sip of water and felt a little better.

Looking at the officials who were lost in thought, a barely perceptible smile appeared on his face.

It’s good that you can still think, it’s okay to doubt life, and it’s okay even if your faith in the Tao collapses.

I am afraid that they have lost the ability to think proactively, and their thinking has become so rigid that they cannot be influenced by anything. Even a god would be unable to save them.

Li Che cleared his throat, and everyone looked up, their eyes full of confusion.

"Okay, you can take the textbooks. You have plenty of time to think about this knowledge.

Physics is different from any other discipline in Daqing today. It is a practical subject with no ideas, only cold rules.

What we need to do is to understand these rules and then apply them to agriculture, military and people's livelihood.

For example, the curved plow and drum cart I asked you to make utilize the mechanics principles you learned today."

Li Che looked at Qiu Bai, who nodded and brought in a large pile of books from outside the house.

Li Che started writing these books on his way to his fiefdom. He was responsible for writing the original text, while Qiubai and Qiuwen were responsible for copying it.

Over time, Qiubai gradually gained a certain understanding of Li Che's theories.

But Qiubai was not one of these scholars. He had no loyalty to traditional Confucianism, so he did not fall into confusion.

On the contrary, he felt that his Highness was a very learned man.

It is such a simple, easy to understand and practical knowledge, how come no one has discovered it for thousands of years?

"Here are two textbooks, Mathematics and Geography. I'll give them to you as well. Everyone can prepare on their own. If you have any questions, feel free to ask me."

Li Che looked at the stunned crowd and said:

"Alright, you guys should calm down a bit. I'm leaving first."

After saying that, he turned and left the house.

As soon as I walked out of the house, I heard heated discussions behind me.

Li Che smiled silently.

In its own world, China has always been a leader in world civilization.

But when the European Industrial Revolution began, the gears of fate began to turn.

The powerful productivity brought about by the Industrial Revolution allowed European countries to overtake others, but the Qing Dynasty at the same time chose to close its doors to the outside world, ruining its lucky cards.

From then on, the Eastern Dragon fell into a deep sleep, and Chinese civilization entered an unprecedented low period.

Less than two hundred years of modern history has obscured the five thousand years of glory of the Chinese nation, causing countless Chinese people, including Li Che, to feel heartbroken.

And in this world, at this moment, in this room, the gears of fate were turned again by Li Che.

This time, Li Che will lead Daqing to become the first country in the world to embark on the road of industrial revolution!

The Eastern Dragon took up the weapon of "Industrial Revolution" just like Sun Wukong wearing the interstellar armor.

I just wonder if this time, the Western countries are ready to face the roar of the dragon?

. . . . . .

Before he had gone far, he heard a voice behind him calling out, "Your Highness, Your Highness."

Li Che looked back and saw Chen Gui running towards him in a hurry.

Li Che asked curiously, "But what don't you understand?"

"Not really." Chen Gui said excitedly, "Your Highness's knowledge is incomparable and I admire you deeply."

"Then what are you doing?"

"Yesterday, I prepared several new types of firearms according to your gunpowder formula. Your Highness, could you please step aside and help me take a look?"

Li Che had no objection and asked Chen Gui to lead the way, and the two of them walked towards the outside of Gongzheng Office.

Since the formula of gunpowder needs to be kept secret, it is no longer appropriate for Chen Gui and the gunpowder craftsmen to live in Gongzhengsuo.

Li Che found him a secluded courtyard, prepared to be responsible for the research and development of gunpowder, and established a new department, the Gunpowder Department.

After entering the gunpowder department, Li Che immediately smelled the pungent smell of gunpowder in the air and couldn't help but frowned.

He also saw a barrel of black gunpowder in the yard, exposed to the sun, and his brows furrowed even more.

"Don't be so careless in placing the gunpowder." Li Che was terrified. "This gunpowder can hurt others as well as yourself. If there is an explosion, everyone in this yard will be in danger of their lives."

"What do you mean, Your Highness?"

"Keep away from open flames and direct sunlight, and don't let the gunpowder get wet. Don't store gunpowder together; it's best to separate it to avoid a chain reaction."

"Temperature is what creates flames. The climate in the north is already dry, and if it's exposed to the sun, the gunpowder could spontaneously combust at any time!"

After hearing this, Chen Gui was secretly frightened.

He had seen the power of black powder before. A small can of it had such a powerful effect. If a barrel of gunpowder exploded...

"I understand. I will give the order right away."

After dealing with the safety hazards, Li Che came to the backyard accompanied by Chen Gui.

Everything in the backyard has been cleared away, and it has now become the Gunpowder Department's testing ground.

Chen Gui brought out a small earthenware jar and presented it respectfully: "Your Highness, this is a fire bomb. It has a fuse and contains a pound of black powder."

"My idea is to ignite this thing and throw it out. It will be easy to carry and can also kill the enemy."

Li Che picked up the earthen jar carefully, looked at it for a while, and shook his head.

Isn't this just a crude version of a hand grenade? It wouldn't be very powerful with just a clay pot and black powder.

The power of black gunpowder is actually just that. The shock wave generated by the explosion is actually difficult to kill the enemy. It is good if the killing radius can be one meter.

"Add some more iron pieces in there," Li Che said. "Use the power of the explosion to shoot the iron pieces out, so that they can be lethal."

Chen Gui's eyes lit up.

Li Che added, a kind smile flashing across his face: "By the way, it's best to use rusty iron sheets."

Chen Gui was stunned.

Why rusty iron sheets?

Why does it feel like His Highness's smile is kind yet a little sinister?
