Li Xingzhong has a soft spot for artillery, and Zhao Guohao looked at the arquebus on the podium and thought about it.

"Instructor, then this arquebus can also be rifled and rear-loaded, as long as the problem of airtightness is solved. Those handcuffs don't need to be lit with a flint, and the arquebus can be changed in the same way? ”

"Zhao Guohao, you have a good question!"

Wang Heyao nodded appreciatively, smiling.

"Absolutely! In fact, many of Tessie's firecrackers have been changed to flintlock firecrackers, which are not limited by the weather and are easy to use. The flintlock torch will be the main firearm of the future, and like artillery, it will be the master of future wars! ”

Wang Heyao said with great interest, he raised his head, and before he knew it, there were people standing outside the window, and the appearance of the dog was impressive.

It seems that these guys really listened.

Maybe one day, these people will be his military officers.

"Instructor, can you tell us a little bit about the flintlock?"

A patrol officer raised his hand and asked, apparently interested in the flint.

If there are hundreds of people, each person has a flintlock firecracker, all over the mountains and fields, and the guns are fired in unison, it is simply terrible!

"The flint is going to be taught in the next lesson. In this lesson, let's talk about artillery first. ”

Wang Heyao took a look at the patrolmen and immediately assigned.

"Zhao Guohao, Li Xingzhong, you take a few people and push the artillery to the training ground, let's teach and practice at the same time!"

The patrolmen cheered, and Wang Heyao was also full of interest.

It's hard to buy people to like, as long as these guys are willing, they will spend a little more time on the training ground in the future.

Today, I will take these new and old inspectors to combine theory with practice.

Seeing the patrolmen go out to carry the artillery, the dog quickly picked up the red tassel gun and left. He hurried forward and grabbed the big head of the bag that was passing on the boulevard.

"Big head, you go on duty for me, just for an hour!"

"Dog, I'm on night duty, and I'm going to sleep!"

Bao shook his head and left.

"Just one hour, my money for this month will belong to you!"

The dog is in a hurry and desperate.

"It's done, it's a deal!"

Bao Datou smiled happily, snatched the red tassel gun from the dog's hand, and hurriedly ran away.

"This miser!"

The dog ran over and saw Zhao Guohao and others pushing the cannon out, and hurriedly shouted.

"Fourth brother, I'll help you!"

The Franc machine gun and the mountain-splitting cannon were pushed to the teaching ground, and the sound of "Pengpeng" artillery continued to sound, and the training ground was thunderous. Wang Heyao watched Thin Monkey and Zheng Siming fight twice, and his brows furrowed.

Compared with the complex and changeable operation of artillery in later generations, the artillery of this era is really much simpler, and the power is also indescribable.

"Adjust the angle of the artillery, 45 degrees has the farthest range, and the closest range when firing horizontally, which is based on the mathematical parabolic principle. However, in the actual exercise and combat process, because of the influence of resistance, it is necessary to actually measure and obtain accurate results. ”

Wang Heyao drew a parabola on the ground while explaining. He picks up explanations that he is familiar with, and pushes those who are not familiar with them to the need for practice.

Everyone nodded unconsciously.

Wang and Yao have two brushes in mathematics, otherwise they wouldn't be able to fool Gao Jiaqin.

"As for the amount of gunpowder, we must keep trying to get the best results. In view of the danger of the cannon exploding, after igniting the wire, hide behind an obstacle so as not to hurt anyone! ”

"The instructor is right! This dosage is a science, a small amount is not powerful, and a large amount has the danger of exploding, but you have to pay attention to it! ”

The thin monkey said in amazement.

"Brother Hou, what you said is not right or wrong!"

Wang Heyao shook his head and didn't give face to the thin monkey.

"The main reason for the explosion is that the quality of the cast cannon is not good, with good steel, the pressure of the cannon chamber is enough, and it is difficult to blow up the chamber!"

"Instructor, what is chamber pressure?"

Li Xingzhong asked again in a daze.

"Chambering pressure is the pressure of the gas produced in the chamber of a gun when gunpowder is burned. That is, the impact force that the gun barrel can withstand. As with boiling water, when boiling, the lid of the kettle is often lifted, which is called the pressure generated by the water vapor. ”

Wang Heyao's words, everyone understood and didn't understand, they all nodded, as if they suddenly realized.

"Instructor, what's the use of this pressure?"

Li Xingzhong was curious to kill the cat, broke the casserole and asked to the end.

"What's the use? In the case of artillery, the better the gunpowder, the greater the pressure generated, and the farther the shells will fly. You say, is this pressure useful? ”

After Wang Heyao finished speaking, he looked at the inspectors and solemnly took the matter.

"I'm not afraid to tell you that this water vapor will cause an industrial revolution in the future. Life. If you think about it, steam drives ships and wagons without manpower, and the whole era will change! ”

Wang Heyao's words caused an exclamation.

Everyone looked at Wang Heyao with surprise and admiration.

Admiration is of course easy to understand, Wang and Yao are both civil and military, and can do anything.

As for the surprise, of course...... The cranky, gibberish neurotic.

"Second, help move the artillery! How are you lazy? ”

Li Xingzhong urged Sun Jiachun, who was hanging.

"Who knows if it's useful!"

Sun Jiachun said angrily, and turned his gaze to Wang Heyao, who explained knowledge to the students and talked loudly.

"What Lao Wu said seems to have some truth."

Li Xingzhong couldn't help but be stunned.

"I just can't get used to seeing the fifth self-righteous look!"

Sun Jiachun snorted and walked away.

Li Xingzhong looked at his back and shook his head.

It seems that Sun Jiachun seems to have some prejudices against Wang Heyao.

"Instructor, I heard that "Heavenly Creation" was banned by the imperial court. Is that so? ”

The patrolmen surrounded Wang Heyao, and some people who were not deeply involved in the world asked again.

"Of course it's the imperial court! It's the same as keeping your hair and not your head, it's forbidden to look at it if it's not pleasing to the eye, if it's not good, it's a big knife to serve, depending on whether your neck is hard or hard! ”

A patrolman spoke out boldly, causing everyone around him to shake their heads and sigh.

"Instructor, why does the imperial court ban books?"

Some people already understand, some people still don't understand, and the simple peasant boy Huzi belongs to the latter category.

"Why else, I'm afraid you'll rebel! Don't talk about firearms, martial arts training is banned! This dog court, a belly of bad water! ”

Zhao Guohao glared and said angrily.

"Be quiet, the wall has ears, the wall has ears!"

The thin monkey's face turned red and he looked around nervously.

"What are you afraid of, your head has fallen off a bowl and a big scar, a bunch of useless cowards!"

Zhao Guohao said angrily, facing the inspectors, mercilessly.

"The government is sitting in a row, and it would rather kill 3,000 by mistake than let one go. If anyone says this today, everyone will kill him together! ”

"Fourth brother, don't worry! Who would dare! ”

"No one dares to do that!"

As he spoke, all the inspectors looked at Wang Heyao.

Who doesn't know that Instructor Wang Touwang is the proud protégé of the county master.

"Okay, I have to train on duty in the afternoon, let's go eat and rest!"

Wang Heyao's face was calm, and he didn't seem to hear anything.

Step by step, rebellion against this thing, you have to take your time, don't be in a hurry!

Let's let the bullets fly for a while!
