Su Ting pointed to the erected rear sight: "What is this thing used for?"

"To correct the height of the muzzle, there is no scale added now. Let Ziyi and others repeatedly test the single point of impact of the bullet, and then add the scale after obtaining the data.

In conjunction with the front sight, the circle on the front sight is used to correct and protect the front sight and delineate the sighting range.

Of course, the rear sight can be a blocking caliper type, but now it is more convenient to use the standing one..."

Li Yi explained again, if a gun is imitated, it should be imitated? Do you understand the principle?

"Show me." Bi Gou reached for the gun.

Guo Ziyi handed it over carefully. Bi Gou took it and lowered his hand: "Heavy."

"At 13.6 to 14 pounds, it looks heavier than an ordinary bow, but the bullet is light and easy to carry. If the gun is too light, it will be inaccurate.

The wall of the barrel is thin. If you want to increase the amount of propellant or change the formula of the propellant in the future, it will not be usable and it will explode.

Transport the cement to the border to build the city, and ordinary people learn how to use firearms. Wait until..."

Li Yi knew that the gun was a bit heavy, and he did so on purpose to prepare for future upgrades.

Everyone needs to get used to the same weight first, otherwise the one that is lighter now will be heavier in the future, and it will not be comfortable to use.

There is another reason.

"There will be a bayonet attached to the gun. When the enemy is close, use the sword to fight. I have a tutorial on how to fight with the bayonet. You must have a sense of weight when swinging it."

Li Yi said what he least expected to see was a hand-to-hand fight.

However, an army that has never dared to engage in hand-to-hand combat will lose even if you give it artillery.

At that time, when Japan first invaded, the Chinese people could not fight with bayonets and did not know how to play.

Later, you will fight hard. The key is not to be afraid of death.

Nepal has a scimitar army that never loses in hand-to-hand combat. It’s not just that the Nepalese scimitars are great, it’s that the people in the army dare to fight.

However, they have lost before. They lost to Li Yi's army at that time. Hand-to-hand fighting is just fighting to the death! Then come on.

During the war on the Goryeo Peninsula, the Nepalese scimitar troops were hired to fight with the Rabbit Army with bayonets, but they never fought against the Rabbit Army.

Today's Tang Dynasty is also the same, the rifle is equipped with a bayonet, the gun is heavy, the barrel is not only thick, but also long.

When shooting, the bullet can fly farther, and when fighting with a bayonet, you won't suffer too much loss.

Speaking of the bayonet, Guo Ziyi took out the bayonet. The long bayonet with a blood groove was made of the same kind of steel as the gun barrel.

He mounted the bayonet and jammed it, and the gun instantly gave people a different look, as if it had a murderous intent.

"It seems to be easier to use than a bow. If the distance between the bow and the bow is too tight, it can only be smashed and twisted, and it is not strong enough."

Song Jing carefully touched the back and side of the bayonet with his fingers, not daring to touch the blade. Only when he was holding it himself did he dare to test the blade with his fingers sideways.

"If you can't fight with the bayonet, don't fight with the bayonet. The gunman should stay away and fight."

Li Yi felt sorry for his Tang soldiers and was willing to use long-range weapons to deal with the enemy.

You can spend more money, it’s worth exchanging money for life!

"How much does it cost?" Bi Gou swallowed his saliva and asked without confidence.

"Lao Bi, hold on, don't be afraid, I'll give you the money from selling the bicycle, you don't have to buy it, it was promised at the beginning."

Li Yi was afraid that Bi Gou would collapse suddenly. Is there any good equipment here?

"Huh~~" Bi Gou said in a long voice: "Yes, I told Xiao Yi that there is no tax on bicycles and guns. I will never do business at a loss."

Bi Gou became hardened in an instant. Look, how far-reaching I am thinking.

"You want to make 60,000?" Wei Zhigu calculated the number of people, 30,000 Yulin Feiqi and 30,000 recruits trained in Taibai Mountain, 60,000.

"This summer Zhuangzi will launch a hydraulic stamping machine. When smelting it, I will add other things to make alloy steel for use in the stamping machine."

Li Yi didn't say how many to build, he gave a new technology.

It is too laborious to make steel pipes manually. It is fast to put them on a stamping machine and hot-roll them.

The cost is not important, his coal is free of charge, and his iron ore is not paid for. Zhuangzi supplies large quantities of saltpeter for gunpowder.

This is a military industry, so all materials are provided for free, and the money earned from selling kerosene is used to subsidize the cost of other auxiliary materials.

He won't give any money for the oil. It belongs to Li Jia Zhuangzi to provide technology and produce military materials. The extra money will be regarded as a reward.

What is considered is the material cost, labor cost and technical cost. No one will calculate it with him.

Labor costs are high, but what is even higher is technology!

This gun has transcended the material stages of cast iron and cast copper, the matchlock stage, the front charge stage, the smoothbore stage, and the linear rifling stage.

Can anyone define how much this technology is worth? It’s equivalent to a span of thousands of years.

There are also changes in the concept of combat and the way of war.

"Li Yi, if this gun is made bigger, like a bed crossbow..." Su Ting suddenly had an idea.

"Su Zaifu has a great idea. The gun is enlarged to become a cannon. I made mercury fulminate and turned it into a fuze device. We can shoot it out with one shot and the shells will bloom."

Li Yi gave a thumbs up. My Prime Minister Su is awesome. He has an idea, which is great.

"Can it still bloom? Like grenades and explosive packets?" Su Ting knew that the weapons transported to the front line were ignited and then thrown out.

What he originally wanted to do was to fire larger bullets, far away, to hit the enemy general. Once the bullet was fired, all the people on the road would be smashed, and in the end the enemy general would die.

Replace it with explosive bullets, like explosives thrown from a catapult.

"Yes, as long as you take out the mercury fulminate, the rest can be easily solved. Add a spring device in front of the cannonball, which will ignite the mercury fulminate when it encounters impact, and then..."

Li Yi gestured, and it looked like an explosion. It was as simple as that. The premise is that the industrial foundation is okay.

"This is so good, Xiao Yi, let's create it." Now Bi Gou wished he could lead an army to fight Tibet directly.

"Money. It's fun to blast it with a cannon. It's a lot of money. Don't count anything else. One cannonball fired can make an average family in Jingzhao Prefecture half a year's income."

Li Yi had already calculated the price. The current production conditions are too poor and there is a lot of manual involvement.

Making one cannon shell, including all costs, requires 20 yuan, which is half a year's income for a family.

Of course, it will become cheaper in the future, and he will gradually improve the process and come up with new technologies.

With a good lathe, you can make more and better lathes, and a generation of lathes will become cultural relics.

Bi Gou did the math, then suddenly lowered his head and sighed, he couldn't afford it, it was too expensive, and what he got after the fight might not be enough to get his money back.

"Xiao Yi, it's better to wait and don't do anything." Bi Gou knew that Li Jia Zhuangzi couldn't bear it, and he didn't want to give money.

"Don't make it? If you don't make it, it will never happen. Only by making it can you slowly reduce the cost.

Even if it's 20 cents for a cannon shell, I'm willing to pay 200,000 cents for 10,000 cannon shells.

Put the artillery team in the city and use the current indirect aiming method.

Coupled with the cavalry in the city, a few hundred rounds can stun the enemy, and no formation will exist in front of the artillery."

Li Yi shook his head. He wanted to make it, but the calculation method was different.

Twenty thousand cannon shells, one shot to kill one enemy, ten thousand cannons to kill ten thousand enemies, two hundred thousand cans.
