Zhu Yuanzhang didn't know a few big characters in the early days of his business, but after getting to know Li Shanchang, Liu Bowen and others, he also began to work hard to learn cultural knowledge. Later, after decades of precipitation, he became an emperor, and he was already half a scholar.

But today, in front of Qin Yu, he once again felt like an illiterate person.

"Excuse me, sir, what is physics and chemistry, please advise." Zhu Yuanzhang arched his hand to Qin Yu.

"Physics is a discipline that studies the most basic laws of motion and the basic structure of matter." Qin Yu began to popularize science for him seriously, "As the leading discipline of natural science, the research of physics is as large as the universe and as small as the particle ......."

Universe? Particle?

Zhu Yuanzhang's eyes were round, like listening to a book from heaven.

"Let's put it simply," Qin Yu felt that it was too profound to popularize science for people who had never been in contact with physics, and it must be close to reality, "If you study meteorological physics thoroughly, you can accurately predict whether there will be abundant rain and whether there will be a major drought in the coming year." Being able to know if it's going to be sunny or rainy in the next few days is great for growing crops......"

Can you accurately predict the weather?

Zhu Yuanzhang was immediately shocked: this is simply too helpful for marching and fighting. I remember that Zhuge Liang once said that the generals do not know the sky, do not know the geography, and are mediocre.

It was because he calculated that there would be heavy fog in the next three days that he dared to borrow arrows from a grass boat.

If you learn meteorological physics, you can be like Zhuge Liang, knowing the time of the sky?

Moreover, it can predict rain and drought, which is also of great significance to the national economy and people's livelihood. If you predict and prepare in advance, you can avoid all kinds of natural disasters and save hundreds of thousands of Li people!

Throughout the ages, there are only a handful of great sages who can know the time of the day, and the young man in front of him actually said that he wanted to teach this knowledge!?

Could this man be a god?

It is rumored that the ancient sages who know the time of the day, Zhuge Liang, Jiang Ziya, and Zhang Liang are almost all immortals.

Seeing that 'Uncle Huang' was attracted by his popular science, Qin Yu struck while the iron was hot, "As for physics, even as small as particles, it is even more powerful." Have you heard of the atomic bomb and the hydrogen bomb? An atomic bomb could easily destroy a city of a million people. The reason why the atomic bomb can produce such a huge destructive power is because of particle fission. ”

Destroy a city of millions of people? Can't live for decades?

Isn't this the power of the gods?

Zhu Yuanzhang suddenly felt a dry mouth: "Sir, you shouldn't be pretending to be bragging, right?" ”

Actually say I'm bragging? Qin Yu suddenly felt speechless: You haven't even heard of the two atomic bombs used by the beautiful country to bomb Xiaori back then, right?

Forget it, he probably hasn't heard of it, because he just thought that I was going to teach the Four Books and the Five Classics.

He has become disconnected from the world.

His cognition is still stuck in ancient times. Even if he said that there was an emperor outside, it was not unusual at all.

He didn't argue with him at the moment, and said, "If you don't believe me, I can't help it, I can't build an atomic bomb to show you right now." That kind of super killer weapon is not so easy to make. ”

"As for chemistry, it is the basic natural science that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels." Qin Yu said, "The example used in life is that I can easily make soap for you." Of course, the pesticides and herbicides used in agriculture are also produced on the basis of chemistry. ”

"Pesticides, herbicides?"

"Yes, pesticides and herbicides are highly toxic, and a small bottle cap can poison dozens of people." "Of course, it is also of great help to agricultural production, because herbicides only remove weeds and do not harm crops." ”

A small bottle cap can poison dozens of people, could it be that chemistry is used for research? Zhu Yuanzhang wondered in his heart, herbicides only remove weeds and will not harm crops, is there spirituality?

"In addition, chemistry also has terrible lethality in war, and this weapon is called biological weapons. Chemical and biological weapons can cause large-scale disease or mass death of people, animals, and plants, but they are now banned because they are so inhumane. ”

"Isn't the mass disease and death of men and animals the same as the plague spread by the plague god?" Zhu Yuanzhang said.

"It's pretty much the same." Qin Yu smiled. I remember that in "The Romance of the Gods", there were four plague messengers, who used magic weapons such as headache chime to scatter plague whips and spread plague everywhere, causing a large number of deaths among the people of the Western Zhou Dynasty.

However, it was the first time he had heard of a biochemical weapon as a plague god spreading plague.

"Listening to what Mr. said, the two disciplines of physics and chemistry are simply unimaginable." Zhu Yuanzhang said.

"Of course." Qin Yu said. Physics and chemistry have promoted the development of civilization in human society, can it not be amazing?

received an affirmative answer, Zhu Yuanzhang's heart was extremely shocked:

If what the young man in front of him said was true, it would definitely bring earth-shaking changes to the Ming Dynasty.

Predict the time of day and avoid natural disasters. Pesticide herbicides that remove weeds without harming crops. A mass killer that can destroy a city of millions of people at once. A biochemical weapon with the terrifying effect of the plague god spreading the plague.

If I master this kind of knowledge, within three years, the people will be rich and the country will be strong, open up the territory and expand the territory, and all countries will come to the court.

With such immortal means, could it be that this person is an immortal from the heavenly realm?

And he also said that he wanted to spread these two knowledges, and he was specially sent down by God to strengthen my Ming Dynasty?

Although Qin Yu said it, he could only understand one-twelve, and most of it was beyond his cognition, and it was a bit fantastical. But he can keenly feel that the other party doesn't look like he is bragging.

As the founding emperor, Zhu Yuanzhang has extremely keen judgment. Whether you look at people or things, you rarely make mistakes. Back then, he promoted Li Shanchang, Liu Bowen, Hu Weiyong and others, just to see the right person.

When he fought a decisive battle with Chen Youliang, it was also because he had insight into the fighter plane that no one could see, and he defeated Chen Youliang in one fell swoop.

This kind of judgment is innate to him, and others can't learn it if they want to.

His success was not accidental.

"How about Uncle Huang, would you like to support me to stay and teach the children in the village this knowledge?" Qin Yu asked, "I don't want to see your village fall so backward again, I want to lead you out of the mountains." ”

"First, to repay Uncle Huang for saving his life, and secondly, it is also my original intention to come to the mountainous area to teach."

"Sir is so enthusiastic, of course we agree with 10,000." Zhu Yuanzhang said.

"That's great." Seeing that the village chief was moved by himself, Qin Yu became excited, "Then ask Uncle Huang to arrange a place for me to be a school as soon as possible, and then announce this matter to the villagers, so that the children can go to school as soon as possible." ”
