Su Yi pointed at the upright door: "What is the use of this thing?"
"To adjust the height of the muzzle. We have not added any markings yet. Let Ziyi and the rest test the bullet repeatedly and add markings after we get the data.
Together with the front sight, the circle on the front sight is used to adjust and protect the front sight, and to define the scope.
Of course, the door can be a blocking type or a caliper type. It is more convenient to use the upright one now … "
Li Yi explained again. A gun can be copied just like that? Do you understand the principle?
"Let me see." Bi Goo stretched out his hand to ask for the gun.
Guo Ziyi carefully handed it over. Bi Goo took it and lowered his hand: "Heavy."
"13.6 kg to 14 kg. It looks heavier than a normal bow, but the bullet is light and easy to carry. If the gun is too light, it will not be accurate.
If the barrel is thin, it will not be able to increase the amount of propellant or change the propellant formula in the future as it will explode.
When the cement is transported to the border for construction, ordinary people will learn how to use guns. When the time comes … "
Li Yi knew that the gun was a little heavy, but he did it on purpose to prepare for future upgrades.
Everyone has to get used to the same weight first. Otherwise, if it is light now and heavy in the future, it will not be convenient to use.
There is another reason.
"When the enemy is close, use the bayonet. I have a tutorial on bayonet fighting. When you swing the bayonet, you have to have a sense of weight."
Li Yi said what he did not want to see the most, a hand-to-hand battle.
However, the army did not dare to fight hand-to-hand. Even if they gave him guns, he would still lose.
When he was first invaded by the Japanese Empire, his countrymen could not win in a hand-to-hand battle and did not know how to play.
Later, they learned how to fight. The key was that they were not afraid of death.
There was a scimitar unit in Nepal. They had never lost in a hand-to-hand battle. It was not that the scimitars were strong, but that the people in the unit dared to fight.
However, they had lost before. They lost to Li Yi's army at that time. A hand-to-hand battle was a matter of life and death! Then come at me.
In the war on the Korean peninsula, the Nepalese scimitar unit was hired to fight the rabbit army with bayonets, but they lost.
It was the same in the current Tang dynasty. Rifles were equipped with bayonets. The gun was heavy. Not only was the barrel thick, but it was also long.
When shooting, it could make the bullets fly farther, and when fighting with bayonets, it wouldn't be too much of a disadvantage.
Speaking of bayonets, Guo Ziyi took out the bayonet. It was a long bayonet with blood grooves. It was made of the same kind of steel as the gun barrel.
He loaded the bayonet and jammed it. The gun instantly gave off a different feeling. It seemed to carry a murderous aura.
"It looks better than the bow. If the bow is too close, it can only smash and twist. It's not sturdy enough."
Song Jing carefully touched the back and sides of the bayonet with his finger. He didn't dare to touch the blade unless he was holding it himself.
"If you don't have to fight with bayonets, then don't fight with bayonets. Gunners should fight from afar."
Li Yi felt sorry for the soldiers of his Tang dynasty, so he was willing to use long-range weapons to deal with the enemy.
Even if he had to spend more money, it was worth it to exchange money for his life!
"How much does it cost?" Bi Goo swallowed his saliva and asked weakly.
"Old Bi, hold on. Don't be afraid. I'll make it with the money from selling the bicycles. You don't have to buy it. We've already agreed on this."
Li Yi was afraid that Bi Goo would suddenly collapse. There was no good equipment here.
"Phew ~" Bi Goo let out a long sigh. "Yes, I've already told Xiao Yi that I won't collect taxes on the bicycles, but I'll make guns. I'll never make a losing deal. "
Bi Goo became firm in an instant. Look, I've thought so far ahead.
"You want to make 60,000?" Wei Zhigu calculated the number of people. 30,000 Winged Knights and 30,000 recruits trained in Taibai Mountain. That was 60,000.
"This summer, Zhuangzi will produce a hydraulic press. During the smelting process, I'll add other things to make alloy steel for the press."
Li Yi didn't say how much he wanted to make. He just gave him a new technology.
It was too laborious to make steel pipes by hand. Putting them on the press and hot rolling was fast.
The cost wasn't important. He didn't need to pay for the coal or the iron ore. Zhuangzi would provide large quantities of saltpeter for gunpowder.
This was a military project. All the materials were free, and the money earned from selling kerosene was used to subsidize the cost of other auxiliary materials.
He didn't need to pay for the oil either. The Li Family Zhuangzi would provide the technology and produce military materials. The extra money would be considered a reward.
He considered the cost of materials. No one would calculate the cost of labor and technology.
The cost of labor was high, but the cost of technology was even higher!
This gun had skipped the stages of cast iron and cast copper. It had skipped the stages of slow match, front loading, smooth bore, and straight rifling.
Who could define how much this technology was worth? It was equivalent to a thousand years.
There was also the change in the concept of battle and the way of war.
"Li Yi, if we make this gun bigger, like a ballista …" Su Yi suddenly had an idea.
"Su Zaifu, good idea. If we make the gun bigger, it will be a cannon. I will make the mercury fulminate into a fuse device. When we fire, the shell will explode."
Li Yi gave a thumbs up. My Prime Minister Su, you have a good idea. Very good.
"It can explode? For example, grenades and explosives? "Su Yi knew that the weapons transported to the front line were ignited and then thrown out.
He originally wanted to fire a bigger bullet from far away and hit the enemy's general. When the bullet was fired, the people on the road would be smashed to pieces. In the end, the enemy's general would die.
If he changed it to an explosive bullet, it would be like the explosives thrown out by a catapult.
"Yes, as long as the mercury fulminate is taken out, the rest is easy to solve. Add a spring device in front of the shell. When the shell is hit by the impact, the mercury fulminate will be ignited, and then …"
Li Yi gestured the explosion. It was that simple. The premise was that there was no problem with the industrial base.
"This is great. Xiao Yi, make it." Bi Goo couldn't wait to bring an army to fight Tubo.
"Money. It's fun to use the cannons, and there's a lot of money. Let's not talk about other things. The cost of one shell is half a year's income of an ordinary family in the capital. "
Li Yi had already calculated the cost. The current production conditions were too poor, and there were too many manual labor involved.
To make one shell, the total cost was 20 liang, which was half a year's income of a family.
Of course, it would be cheaper in the future. He would gradually improve the production process and come up with new technologies.
With a good lathe, he could make more and better lathes. A new generation of lathes would become a cultural relic.
Bi Goo also calculated and suddenly lowered his head and sighed. He couldn't afford it. It was too expensive. The items obtained after the shooting might not be able to cover the cost.
"Xiao Yi, let's wait. Don't make it." Bi Goo knew that the Li Family's Zhuangzi couldn't afford it. He also didn't want to pay the money.
"Don't make it? If we don't make it, we will never have it. Only by making it can we slowly reduce the cost.
Even if it's 20 liang per shell, I am willing to pay 200,000 liang for 10,000 shells.
Place the cannons in the city and use the current method of aiming.
With the help of the cavalry in the city, a few hundred shells would be enough to stun the enemy. Any formation would be useless in front of the cannons. "
Li Yi shook his head. He wanted to make it. The calculation was different.
20 liang per shell. One shell could kill one enemy. Ten thousand shells could kill ten thousand enemies. That would be 200,000 liang.
How much money would it take for an enemy to grow up? How many people would the enemy have?
