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

Chapter 166 I'm afraid you haven't seen Mark Qin
"Sir, how can the granulation technology be realized?" Zhu Yingrao asked.

"It's very simple." Qin Yu said, "that is to mix and grind the correct proportion of saltpeter, charcoal, and sulfur, add water, mix it, dry it, and then carefully knock it into fine particles."

It was so!
These two simple knowledge points have brought about a qualitative change in the traditional black powder!
No advanced technology is required at all.

Simply amazing.

This wonderful effect is four or two thousand pounds.

And the first to discover it, is undoubtedly great.

"Then, Mr. Qin, how did you make the fire gun fire instantly?" Xu Da raised his hand again and asked.

"It's just a simple mechanical principle." Qin Yu said, "Traditional fire guns belong to the category of fire door guns." He picked up the home-made improved fire gun and showed it to the crowd, "This small hole on the wall of the medicine room is called Fire doors, the ancients usually inserted red-hot iron wires, or used lead wires to ignite the gunpowder in the medicine chamber, and then fired the iron pellets out."

"This old way of shooting is very cumbersome and time consuming."

"And if you want to achieve instant fire, it is nothing more than improving the ignition system."

"Have you seen the ignition device I made? This part is called the hammer, this part is called the fire anvil, and this part is called the medicine pool... The flint on the hammer hits the fire anvil violently to cause sparks, and the spark ignites the medicine pool. The gunpowder will cause the gunpowder in the medicine room to explode, thus achieving the effect of firing bullets. This is also very simple, you can understand it at a glance.”

"The conditions in Lujia Village are really rudimentary. Otherwise, the teacher can add insurance on it. Create a safer and more powerful musket."

The crowd rushed over to check, and as expected, the launcher made by Mr. Qin was also very simple.

They understood at a glance.

"Sir, this is what you often say, knowledge is power?" Lu Qingqian said with wide eyes.

"Let's put it this way." Qin Yu said, "Only with the change of the ratio of saltpeter, sulfur and charcoal, and the two knowledge points of 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 instant-on technology, it only uses the simplest mechanical motion in physical science."

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

The improvement of black powder and the improvement of the ignition device, no matter which one is enough to make him go down in history.

"Haha." Qin Yu smiled slightly, and liked seeing them look like they had never seen the world before.This ancient technology is not at all good outside, okay?Atomic bombs and neutron bombs can already be produced outside.

However, seeing how they have never seen the world, isn't it the joy and meaning of teaching volunteer teachers to lead the backward people to civilization?

"Mr. Qin, you are amazing." Han Yan'er's beautiful face also showed admiration.

"The teacher's improvement of traditional fire guns this time uses chemical knowledge. For example, the proportion of materials is used in chemical balance. Granulation technology and flint technology use physics..."

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

"Teacher, we are already studying hard!" Zhu Biao said, "The strength of the two god-like subjects taught by Mr. Master has already shown its power, and we are afraid to hear even a word of what you say, teacher. , it's all written down in the notebook."

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

However, I like it!

I glanced at the people who were studying and found that they were all studying very seriously, even Xu Da was no exception.

Can't help but feel complacent about their teaching methods, combining theory with practice can fully mobilize their enthusiasm.If ordinary teachers just follow the script, the students will not 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 could only get a few points in the exam... As long as they had the enthusiasm of these students, they would have gone to prestigious schools long ago.

Of course, there were also problems with the teachers at that time and the inappropriate teaching methods.

If everyone taught like I did, there would be few people who didn't like to learn.

"Mr. Qin, the fire gun you improved is too powerful. If you use it on the battlefield, I don't know how many people will die at his hands in the future." Zhang Laodao sighed, "It's really hurtful."

Use it on the battlefield?You think too much, who would use this old antique in the modern battlefield?
Qin Yu felt depressed in his heart. Your old-fashioned thinking is still in the Ming Dynasty. You don't know that more advanced weapons have been used outside, but it's no wonder you.Nor did he try to argue with him, or argue with someone whose ideas were not of the same era, it was stupid.

An improved fire gun can hurt heaven and earth?I'm afraid you haven't seen Maxim, the atomic bomb.

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

"Mr. Qin, I really don't know, whether you are a saint who saves thousands of people, or a devil who brings disaster to the world." Zhang Laodao sighed, "You don't know, once you use this thing, how many people will be affected by it. Lost my life. My old Zhang, I'm getting more and more unable to see through you."

"You are wrong." Qin Yu said lightly.

Mr. Qin actually said that Zhongxiao Shenxian was wrong?The crowd listened, shocked again.

"What did I do wrong?" Zhang Laodao asked in surprise.

"The invention of advanced thermal weapons not only did not promote the war and increase the number of deaths, but to a certain extent, prevented the war." Qin Yu said.

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

"Without advanced weapons, wouldn't people fight wars?" Qin Yu said, "No!"

"Without advanced thermal weapons, people would still use knives to kill. Ancient humans before knives were created would still use stones to kill enemies. The weapon itself has nothing to do with war, and talent is the root cause of war."

"It makes sense!" Xu Da said, "Where there are people, there will be rivers and lakes, and there will be wars."

"Old 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,
"Then why is it that the more advanced the weapon is, the better it can prevent war? Take Xiaotian as an example. If the United States did not drop two atomic bombs on Nagasaki and Hiroshima to destroy their two cities, do you think Xiaotian would be safe?"
