"Sir, how can granulation technology be realized?" Zhu Yingrao asked.

"It's simple." Qin Yu said, "That is, the correct proportion of saltpeter, charcoal, and sulfur is mixed and grinded, mixed with water, dried in the sun, and then carefully hammered into fine granules. ”

So that's it!

These two simple knowledge points have made a qualitative change in the traditional black powder!

No advanced technology is required.

It's just amazing.

This wonderful effect is to dial a thousand pounds in four or two.

And the first to discover it, undoubtedly great.

"Then Mr. Qin, how did you manage to make the fire bolt instantaneous?" Xu Da raised his hand again and asked.

"It's just a simple mechanic." Qin Yu said, "The traditional fire gun belongs to the category of fire door guns. As he spoke, he picked up the homemade improved musket and showed it to the crowd, "This small hole in the wall of the medicine room is called the fire door, and the ancients generally used a red-hot wire to insert it in, or use a lead to ignite the gunpowder in the medicine room, and then fire the iron pellet. ”

"This ancient way of shooting is very cumbersome and takes a long time."

"And if you want to be instantaneous, you just need to improve the ignition system."

"Did you see the ignition device I made? This part is called the hammer, this part is called the anvil, and this part is called the medicine pool...... The flint on the hammer hits the anvil violently and causes a spark, and the spark ignites the gunpowder in the medicine pool, which will cause the gunpowder in the medicine room to explode, so as to achieve the effect of firing bullets. It's also very simple, you can understand it at a glance. ”

"The conditions in Lujia Village are too simple, otherwise the teacher can add an insurance to it. Build a safer, more powerful musket. ”

The crowd rushed over to check, and sure enough, they found that the launch device made by Mr. Qin was also very simple.

They understood it at a glance.

"Sir, this is what you often say, is knowledge power?" Lu Qingqian's eyes widened and said.

"Let's just put it that way." Qin Yu said, "Just by the change of the ratio of saltpeter, sulfur and charcoal, and the granulation technology, the power of the ancient fire gun can be increased tenfold. ”

"It's not the power of knowledge, what is it?"

"And its instantaneous technology, which only uses the simplest mechanical motion in physical science."

"Mr. Qin, you are really knowledgeable!" Zhu Yingrao sighed......

The improvement of black powder, and the improvement of the ignition device, either of them was enough to make him go down in history.

"Huh." Qin Yu smiled slightly, he liked to see them look like they had never seen the world. Isn't this ancient technology nothing good on the outside? Outside it is already capable of producing atomic bombs, neutron bombs.

However, seeing that they have not seen the world and leading backward people to civilization, isn't it the fun and meaning of volunteer teachers?

"Mr. Qin, you are amazing." Han Yan'er's beautiful face also showed a look of adoration.

"This time, the teacher improved the traditional firecracker, which used chemical knowledge, such as the proportion of materials used in chemistry trimming. Granulation technology and flint technology, using the ...... of physics"

He said earnestly: "So, you must study physics and chemistry well in the future, these two natural disciplines!" ”

"Teacher, we're already studying hard!" Zhu Biao said, "The power of the two god-like disciplines taught by Mr. Zhu has already shown its power, and we are afraid that we will hear a word you say, so we will record it all in our notebook." ”

God-like disciplines? Qin Yu smiled again, it's really funny that you haven't seen the world.

I like it, though!

glanced at the crowd of students and found that they were all very serious in learning, even Xu Da was no exception.

I can't help but feel comfortable with my teaching methods, and the combination of theory and practice can fully mobilize their enthusiasm. If the average teacher is like this, he just reads from the book, and the students are not willing to study seriously.

"It's hard for you to be so thirsty for knowledge, the teacher is so gratified." Qin Yu sighed.

I remember when I was in junior high school, there were several students in my class who didn't like to study physics and chemistry, and they could only score a few points in the exam...... As long as they had the learning energy of this group of students, they would have gone to a prestigious school a long time ago.

Of course, there was also the problem that the teachers at that time did not teach properly.

If everyone teaches like me, I don't think there will be many people who don't like to learn.

"Mr. Qin, the power of the firearm you improved is too great, if it is used on the battlefield, I don't know how many people will die in his hands in the future." Zhang Laodao sighed, "It's really hurtful." ”

Used on the battlefield? You think too much, who would use such old antiques in the modern battlefield?

Qin Yu was depressed in his heart, your old Taoist thinking also stayed in the Ming Dynasty, you didn't know that more advanced weapons had already been used outside, but it was no wonder that you were so strange. It would be foolish not to try to argue with him, with people whose thoughts were not of the same time.

A modified fire gun will hurt the heavens and harmony? I'm afraid you haven't seen Makqin, the atomic bomb.

Well, you really haven't seen it, you haven't even heard of it.

"Mr. Qin, I really don't know, are you a saint who saves thousands of people, or a demon who brings disasters to the world." Zhang Laodao sighed, "You don't know how many people will die once you use this thing." I, Lao Zhang, can't see through you more and more. ”

"You'd be wrong." Qin Yu's surging Dao.

Mr. Qin actually said that the immortals of loyalty and filial piety were wrong? The crowd listened, shocked again.

"How did I go wrong?" Zhang Laodao asked in surprise.

"The invention of advanced thermal weapons, instead of fueling wars and increasing the number of deaths, has, to a certain extent, prevented wars." Qin Yu said.

"What's the reasoning?" Zhang Laodao asked. The rest don't understand either.

"Without advanced weapons, people don't fight?" Qin Yu said, "Definitely! ”

"Without advanced thermal weapons, people would still fight with knives. Before the sword was made, ancient humans would still stone their enemies to death. The weapons themselves have nothing to do with war, and talent is the root cause of war. ”

"Makes sense!" Xu Dadao, "Where there are people, there are rivers and lakes, and there are people who have wars." ”

"Lao Xu is right, as long as there are people in society, war will always exist, and war will not disappear because of any factors." Qin Yu said,

"So why is it that the more advanced the weapon, the more it can stop the war? If the United States had not dropped two atomic bombs on Nagasaki and Hiroshima to destroy their two cities, would you think that Little Day would be safe? ”
