.Dang Paiguo was on the way to analyze the inevitability of hot weapons to replace cold weapons for students about Cao Cao's question. His eyes had jumped over the students and saw a "human weapon" pulled by two big green donkeys behind them, which was thick, big, black and long, and could shoot very powerfully.

Well, although it was used to describe the beautiful girl's face and heartbeat, to put it bluntly, it was just a bronze cannon cast. After the Party Patriotic answered Cao Cao's question briefly, he took the students over to see the cannon.

"Let's take a look. This is the gunpowder weapon that Cao Cao guessed that the range is far higher than that of the bow and arrow - artillery. Like landmines, I won't say anything. Let's first look at the attack method of artillery, and then you will tell me what is the difference between the principle of artillery, the anti-destruction method and use of mines and bows."

Dang Aiguo led the students around the cannon with a gun mount for a few times, patted the cannon with his hands, and asked the students several questions to think about it. Then, after the students saw how the smoothbore cannon was loaded in front of the door, he ordered the students and soldiers to enter the half-buried observation bunker again, and he took the red-burned fire chisel to the anus behind the cannon... No, poke the fire door hard!

"Boom! Crackla? Crackla? Crackla…"

With a loud bang, a burst of smoke came out of the black hole's gun's mouth, and the huge and heavy gun body moved back dozens of centimeters. At the same time, several trees broke inexplicably in the woods less than a hundred meters away in front of the gun.

At this time, Dang Aiguo asked them to come out of the observation bunker and go to the woods to observe in person. After they found the solid shells stuffed into the guns in the woods, they confirmed that they were really not dazzled. At the moment of firing the guns just now, their eyes seemed to see a afterimage rushing out of the guns, but they seemed to see nothing.

Come back to my senses and look at the woods that seemed to have been ravaged by some legendary monster. The trees as thick as the altar seemed to be slapped by the monster. The stubble on the broken mouth was a bit creepy. What made people feel that the ugly and terrifying appearance of the monster named "Architecture" emerged in their hearts was not the ugly and terrifying appearance of the monster named "Architecture", but its incredible powerful force.

After they returned to Dang Aiguo with some warm shells, Dang Aiguo asked again: "How is it? As far as I know, even the largest giant crossbow now can only break a few trees as thick as a bowl. You will definitely not doubt the power of the cannon. My question now is, what is the difference between the principle, anti-destruction and use of the cannon and mines and bows."

After thinking for a while, the students of Dang Paiguo and others thought, they called Zhuge Liang's brother who had a good relationship with Wang Can and Pang Tong, and Zhuge Jin with a donkey face, and answered.

"…Architecture relies on gunpowder explosion to push shells, landmines rely on explosion to generate debris, and bows and arrows push arrows through the elastic force of strings.

In terms of use, artillery and mines attack and defend. The artillery is bulky but powerful, and can be a powerful weapon for siege. If the two armies confront each other, it is better to use lighter and more flexible bows and arrows."

Zhuge Jin gave his answer concisely and cautiously. Although some of them were not satisfied with the Party and patriotism, he did not show it on his face and nodded to Zhuge Jin with certainty.

"Tiyu's analysis is basically correct. He did not analyze some problems thoroughly, but it was just because the information he obtained was insufficient. Let me correct it. Strictly speaking, the artillery did not push the shells through explosions, but pushed the shells through a large amount of gas generated by the violent combustion of gunpowder. In that case, the air pressure in the barrel was much higher than outside the barrel, so the shells were pushed out.

In addition, artillery can also be used for field battles, and its range is much higher than that of a bow and arrow at a long distance. I just used the direct shooting method. If the gun is raised upwards - just like a bow and arrow, you can imagine how far a cannonball can be shot so fast. For artillery, it is not uncommon to shoot several miles in one shot, and only a few people are required to operate it.

In addition, artillery has advantages in close combat, so you can retreat a little."

Dang Aiguo said while waved his hand, and the students obediently retreated a few meters behind the cannon. Then they saw the principal of the Party stuffing a smaller gunpowder bag and a cylindrical shell into the muzzle, and were ready to fire.

"Everyone has his ears covered, I'm going to fire!"

After seeing the students obediently covering their ears, the Party and the Patriotic Fired again. After a loud noise, there was a "boom" sound like a pouring rain hitting the ground. Although some students kept their ears tightly and did not hear the sound, they also saw the land far from the muzzle stirring up fine smoke and dust, just like raindrops as big as beans began to fall on the dry and smoked land.

"Okay, everyone doesn't have to go there to see it in person. I will tell you directly that the shells just now are filled with small porcelain beads, one by one. This is the shotgun. If you have a close range, you can kill enemies in large quantities - what I said is that the close range is also farther than the range of a bow and arrow.

Of course, artillery also has its own shortcomings. It is certain that it is not as light as the bow and arrow. After all, you can see that it is a heavy weapon like a giant crossbow, not for personal use. However, artillery not only has great advantages in siege and defending the city, but also in field battles. It can be said to be a weapon called the "God of War".

If you think about it, what if the cannon is made very small and can be fired in your hand? Such a cannon is called a musket. It has a longer range than a bow and arrow, faster than an arrow, and is also very lightweight. More importantly, using a musket to shoot is much more labor-saving than shooting a bow and archery, and the soldiers have stronger continuous combat capabilities.

But you should pay special attention. Although muskets are much smaller than cannons, they are more difficult to manufacture. If the quality of the materials is not up to standard, the muskets produced can only be filled with a small amount of gunpowder, and the range is not as powerful as bows and arrows, and the power of bullets is weak. But if there is more gunpowder, a little fire will blow up the musket directly, and most people who use muskets will not be able to get it."

The Party’s patriotism may be to speed up the course, so after explaining it directly, he took out the last gunpowder weapon. It was a not too thick but very long "white jade pillar". Although it could tempt the thirsty young woman who can only use cucumbers and bananas to "solve problems" every day, it was actually just a simple rocket.

"This is a rocket, which recharges gunpowder in the hollow body. After ignition, the gas generated by the gunpowder is sprayed out from the tail, pushing the rocket to fly towards the enemy.

However, it wouldn't be very meaningful if you just fly over and hurt people with a sharp arrow, so the rocket is divided into two parts. The latter part is the propulsion section, and the gunpowder is specially used to push the arrow body; the first part is the warhead, and the gunpowder inside is used to explode and injure the enemy - and there are also some small porcelain beads."

When Dang Aiguo said this, he smiled "you understand" and did not give any more comments. Many students shuddered and secretly wiped cold sweats. They had already fully understood the style of the Party Principal. Needless to say, the small porcelain beads save money and increase lethality, and they did understand them.

"The Rockets are troublesome. If you don't do it well, it's hard to fly to the predetermined location. It's hard to say where the rocket in my hand can hit, but I'll just put one for you to see. Anyway, there's no gunpowder in the warhead in front, so it's not very dangerous."

This time, the Party Patriotic did not drive the students to the observation bunker to see, but asked them to take a few steps back, squat down and install the rocket on the launcher, and then ignited the fuse at the tail.

"Che"

A choking white smoke rushed out from the rocket's tail, and then the students saw the rocket shakingly flying upwards, then looked up and flew upwards. Then its tail formed a strange and crooked line in the air that only children could draw, and finally turned around and flew towards the crowd.

"Everyone be careful to dodge!"

At this time, Dang Aiguo was also startled and quickly stood in the direction of the rocket flying. Unexpectedly, the rocket that he had made with thick paper was so unreliable. It was indeed not enough to look like it.

The poor rockets of the Party patriotism shook their heads and flew toward this side for a short while, and headed down directly to the ground in front of them. Just as everyone was relieved to see the rocket hit the ground and breathed a sigh of relief, the tenacious rocket had fuel, twisting and rolling on the ground like a snake, and then stopped. The paper-paste arrow body finally started to burn.

Seeing this scene, Dang Aiguo remembered a kind of fireworks he had seen in the past, which ignited on the ground and leaped around. He also breathed a sigh of relief and said to the terrified students:

"Look, for the time being, this kind of rocket is too dangerous and cannot be used at all. However, you cannot give up research and improvement of this weapon just because it is dangerous. At this time, you should first analyze from a theoretical perspective whether this weapon is worth continuing to invest in research and development.

Okay, I have finished watching all the gunpowder weapons that I can watch for the time being. Let’s go back together. I won’t have to stay in the dormitory all the time tonight, and there are good programs.”

The visit to gunpowder weapons was actually not long. After all, Dang Patriotic only detonated a landmine, two grenades, and fired a solid bomb, a shotgun and a rocket. After the students had lunch, they listened to the Party Principal in the canteen in the afternoon to explain the manufacturing and uses of gunpowder - in addition to being used as weapons, such as quarry, mining, entertainment, etc.

The good show that night was actually the fireworks and firecrackers conference in the hot weapon experiment field.

The Party Patriotic was very stingy and only put out three beautiful fireworks, explaining to the amazing students that the colorful fireworks were mentioned before when he was doing metal burning experiments for everyone, and the different colors produced when different metals burned.

Then he set off more than a dozen kicks, asking students to note that the principles of the kicks and rockets are the same. After a lot of education and entertainment, the Party Patriotic country set off a large string of firecrackers.

Finally, when the party who was accused of public welfare and had enough of his own play, he generously sent each student five types of ten small fireworks in total. He simply told them to "be careful of their eyes" and let the students play on their own. At this time, he had to look at the beautiful girls who were excited about playing with fireworks for the first time to prevent them from burning or burning their beautiful skin.
