In the afternoon of the same day, shortly after Chen Xin sent a letter to Amin, Huang Taiji led his army to the Dandong section of the Yalu River, which was across the river from the boundary where Chen Xin was stationed. Pen, fun, and www.biquge.info

Chen Xin and the other officers were on a high ground by the river, looking at the crowd on the other side of the river.

"Is the one in the middle Huang Taiji?"

"It should be him, the guards around him are all wearing cotton armor dyed yellow, so the bag is not a yellow flag."

"I don't think so, Huang Taiji needs to come to the riverside to check it out in person?"

"His son just died here, can he come and see, in my opinion, that person must be Huang Taiji didn't run away."

"Commander-in-chief, have you seen Huang Taiji? Is it him on the other side? The officers were at loggerheads and began to inquire about Chen Xin.

Chen Xin shook his head, "I haven't seen it, but there's no point in arguing about whether it's him on the other side or not, we don't have weapons to fight that far." ”

The other officers also sighed, "It's a pity, if it's closer, we can really kill this guy with a dozen infantry shells." ”

An officer retorted, "Come on, how close is that, he is also an old fighter, how can he run into the range of the artillery." ”

"If only we had the kind of artillery at the head of Ningyuan City, I heard that one cannon can erode dozens of miles."

"My obedient, erosive for dozens of miles? How big did that cannon have to be?

The corners of Chen Xin's mouth twitched, turned around and patted the officer's head full of nonsense, and scolded, "Tong Ziyuan, you kid doesn't even move his brain when he speaks." ”

Tong Laosan covered his head and said aggrievedly, "Commander-in-chief, why am I not brainy?" ”

Chen Xin said angrily, "A cannon has eroded dozens of miles, this kind of thing is said, do you dare to say that you used your brain?" ”

Tong Laosan argued, "Commander-in-chief, that's not what I said, it was written in the Ming Dynasty's military book, if you don't believe it, I'll show it to you." ”

Chen Xin raised his hand again, making it look like he was going to fight, Tong Laosan closed his eyes and waited to be beaten, he didn't feel pain for a long time, and secretly opened his eyes to see that Chen Xin had retracted his hand.

Chen Xin shook his head and said to everyone, "Everyone must remember that it is better to believe in books than to have no books, and you must also use your brains well when reading books. ”

The officers thought carefully for a long time, and they all looked at each other a little, and finally it was the big cat who took the lead and asked the doubts in everyone's hearts.

"Commander-in-chief, what kind of object is the cannon mentioned in the book? Everyone has never seen him, and I really can't imagine how powerful he is. ”

Chen Xin ignored that people in this era do not have the conditions for querying information as conveniently as the Internet, and their cognition of things is only passed on by word of mouth except for books.

For some officers who had no idea what large artillery looked like, they had no way of doubting the correctness of the knowledge in the books.

Chen Xin knew that he was wrong to blame Tong Laosan, and immediately said to him, "I blame you wrong." ”

"Don't, don't, commander-in-chief, didn't you slap me in the face? You're right, it's me who doesn't use my brain. ”

Chen Xin smiled apologetically, and then said, "Then I'll give you a general talk about artillery today." ”

"Actually, the basic construction of artillery is the same now.

With the exception of the Furlong cannon, which is used for rapid fire at close range, which is reloaded from behind, all the others are front-loading guns. The Franc cannon can't go far due to serious air leakage, so I'll talk about it later when I have time, so I'll talk about other long-range guns today.

They differ only in the length of the barrel, caliber, etc.

The barrel is made of cast iron or bronze, and the required chamber is drilled in the middle, and there is a small fire hole at the bottom of the chamber, and the exit of the fire hole is the ignition pool.

The gun was mounted on a wooden gun carriage with a wedge between the tail of the gun and the gun carriage, which was marked with a scale indicating the firing range. By moving the position of the wedge, you can change the muzzle angle. The more advanced version uses a lifting screw.

The Ming Dynasty is more chaotic in the way of naming artillery, there are different by the weight of the gun, there are also according to the material, and there are according to the size of the muzzle, 100 catties, 500 catties, 1000 catties, 3,000 catties, 5,000 catties, 10,000 catties, iron cannons, copper cannons, bowl guns, ・・・・・・, anyway, the current artillery models are very messy, and the names are different in various places.

In order to make it easier for you to distinguish, I will teach you a relatively simple method, that is, to calculate the weight of the projectile fired by the artillery, and you can basically know the power of which artillery through the weight of the projectile.

Today's artillery projectiles, except for scattered bullets, are basically iron spheres, and the diameter of the sphere represents the caliber of the cannon. A direct reflection of the artillery's ability to fire the size of a shell.

For example, 5 kg gun/2 feet 6 inches (84mm), 7 kg guns// 3 feet 3 inches (108mm), 10 kg guns/3 feet 8 inches (121mm).

Although the quality of the guns varies greatly depending on the materials and processes used to cast them, and the amount of gunpowder that can be filled in the barrel varies greatly, the general power can be determined.

The 5-kilogram cannon is basically able to penetrate about 3 people in a row at its maximum effective range.

The 7-pound cannon can basically penetrate about 7 people in a row at its maximum effective range.

The 10-kilogram cannon is basically able to penetrate more than 10 people in a row at its maximum effective range.

I don't know how many people can be pierced by heavier shells, but I think no fool would line up in a tight formation to be bombed in the face of this kind of artillery. ”

Everyone listened with relish, and at this time, Chen Xin's ridicule also amused everyone.

Then Chen Xin continued, "As for long-range weapons, they all have a maximum range and an effective range.

With the strength and accuracy of the current weapon, there is no need for everyone to pay attention to what is the longest range, it is meaningless, you must know that a gun weighing 400 catties, with a barrel length of 4 feet and seven inches (1.5 meters), 9 taels of medicine, and a shell weighing 1 catty, can shoot 1200 steps at the farthest, which is almost the width of two Yalu rivers. ”

This long distance caused everyone to be amazed.

Chen Xin ignored it and continued, "But at a distance of 1200 steps, it is impossible to aim at all, the muzzle of the cannon is fired at the sky, and the shells are almost falling from the sky, which can only be a blind cat touching a dead mouse, and hitting a person is God bless, in fact, the current artillery, the firing distance is more than 200 steps, and the cannonball is a curved arc, with the current level of technology, many times I don't know where the landing point is." ”

Speaking of this, Chen Xin paused for a while, watching the officers marvel at the ultra-long range and powerful power of the artillery, and kept talking to each other.

Chen Xin smiled evilly, and said in the tone of a big bad wolf tempting Little Red Riding Hood, "Although the cannonball will take an arc when it exceeds 200 steps, it is not impossible for the artillery to exert accurate killing at a distance of more than 200 steps, do you want to learn?" I can teach you. ”

Suddenly, all the officers looked at Chen Xin with bright eyes, and everyone shouted away.

"Commander-in-chief, can you really teach us ultra-long-range shooting?"

"I want to learn, I want to learn."

"This is really a miracle skill."

"Taking the enemy's head a thousand steps away is simply the reincarnation of an immortal, and you must learn it."

Looking at the excited officers, Chen Xin's smile became brighter and brighter.

"Since you want to learn, I naturally want to teach, but this is not a trivial matter, each of you hand in a letter of determination to express your determination to learn this technology."

"No problem, I'll write."

"I also wrote, there is such a powerful thing, if you let it go, God will be angry."

"I'll write it now."

"Yes, write now."

Chen Xin's smile was so bright that he couldn't hold it back, revealing his mouth full of teeth, "Finally, I can finally use mathematics to torture others, I want the students of this world to think of me when it comes to the exam season, resentment, come more violently, let your resentment wash away my pain in the past ten years." ”
