That night, everyone went to sleep, and the next morning, everyone ate steamed buns and drank lean porridge.

"Anything that involves flying into the sky, you have to eat buns." Li Yi explained to the four people.

The four of them didn't understand, why did they have to eat steamed buns when they flew into the sky?

"Tradition, we must inherit the fine tradition." Li Yi added, don't ask.

"There are two things today, which are the latest scientific and technological achievements of our Datang so far. One is a weapon, and the gun that Lao Bi talked about. One is a delta glider, which allows a person to fly slowly from a high altitude. ”

Li Yi told the four of them two things and asked the four of them to choose which one to see first.

"Guns!" Bi Gou and Wei Zhigu spoke at the same time.

Song Jing nodded, he didn't care, the gun was the gun.

Everyone knows what a gun is, Li Yi has one, which is very powerful, and he took Guo Ziyi to Songzhou and killed many junior generals in the Tubo army.

Now you can build it yourself, you can equip the army, take a look.

After the meal, a group of people slowly walked towards the shooting range.

Guo Ziyi and Hao Lingquan were waiting at the shooting range, with a long cloth bag next to them.

Guo Ziyi nodded to Li Yi, everything was ready.

Li Yi picked up the cloth bag, untied the open rope, and removed it, revealing the heavy rifle inside.

"This flintlock pistol, which is equipped with lead bullets in a rear-loading paper shell and a spiral rifling on the inside of the barrel, has spanned countless years of technological development at one time."

Li Yi held the gun and introduced, it is indeed not easy, rifling is still a specially made equipment.

The steel pipe is smashed hard, not cast, and there are too many trachomes cast, and the inside of the barrel is not smooth.

The key is that it is easy to perforate and break in the trachoma area, and then blow up the chamber.

"Xiao Yi, how is it compared to your gun?" Bi Gou came over and touched the gun, it was very cold.

"My sniper rifle? Technically, there is a difference between heaven and earth, and there is no difference between shooting at a distance of 60 zhang.

I can't shoot a hundred of these guns with one gun, because the bullets of this kind of gun can kill me at that distance. ”

Li Yi raised his gun and took aim, sinking, his arm couldn't bear it for a long time.

"Can you fight sixty feet?" Song Jing was interested in distance, sixty zhang was more than a hundred steps, and ordinary bows and arrows couldn't shoot.

"Eighty zhang away from the eye is also injured, depending on the amount of gunpowder, more decoration, 100 zhang.

It's just that it's far away, and it's much worse than my gun.

Pulling away, my gun faced a hundred people at a distance of 200 feet, and I could snipe to death.

This gun is due to the fact that I have never made a fire cap, and I have not studied the firing pin primer.

One minute...... Ninety to one hundred and twenty shots in a quarter of an hour, faster than a normal archer. ”

Li Yi emphasized 'normal' and looked at Guo Ziyi next to him.

Guo Ziyi nodded, expressing agreement, it was really fast.

Hao Lingquan spoke: "Where the distance is far, the distance is close, the archer is fast, look at the power of the bow."

If you are fast, you may not be able to penetrate your armor, but even if you shoot at an enemy at close range, the enemy will be able to kill you with arrows.

Distance, bow strength, accuracy, and the opponent's equipment all affect the outcome of the battle. ”

Su Ying also came over to touch the gun: "The biggest advantage is the long range?" ”

"No, the biggest advantage is that the arm will not be strained, and it can be fired all the time, and the archer can't pull the bow if he shoots too much, and at the same time, the accuracy gradually decreases."

Guo Ziyi, in terms of his own feelings, likes to use a bow, and ordinary archers can't bear it.

Li Yi took over: "The other is that the training speed is fast, in case of emergency, teach to shoot a few shots, and ordinary people can fight by themselves." ”

"Hit a dozen, and see." Wei Zhigu didn't want to listen to it, it depended on the actual operation.

So Li Yi gave the gun to Guo Ziyi, this gun belonged to Guo Ziyi, and it arrived in Guo Ziyi's hands in a few days.

Guo Ziyi has been practicing, and thousands of bullets have been missed.

Li Yi didn't want to lose face, he knew what Guo Ziyi's talent in sports was, and he was willing to endure hard training, this gun was given to Guo Ziyi, which could be used as a sniper rifle.

Choose a good position, the target is up, a humanoid target, with arms and legs.

The target was placed at a distance of thirty zhang, Guo Ziyi took out a paper shell bullet, integrated the ammunition, and removed the air-closing rod under the gun.

The airtight parts of this gun are modeled after the Sharps Model 1859 rifle, with the air-closing lever moved down and the bullets loaded from behind.

Then the air-closing rod is raised, and part of the paper behind the bullet is cut off when it is closed.

The flint-band hammer for firing was lifted, and the trigger was raised.

Open the lid of the gunpowder pool next to it, take a cowhide bag, pour a little gunpowder into the medicine pool, and put the lid on the medicine pool.

The muzzle of the gun is pointed at the target, and the head is turned to look at the others, ready to go.

Everyone nodded and picked up their binoculars.

Li Yi spoke: "Left eye." ”

Guo Ziyi raised his gun, aimed at the star with the door, took a look, and hooked the trigger.

The three movements that were almost connected sounded, a puff of smoke came out, and the humanoid target over there bounced in the eyebrows.

"Didn't hit the left eye." Guo Ziyi bowed her head like a child who had done something wrong.

Everyone: "......"

Li Yi nodded in understanding, and said to the others: "If Ziyi uses a bow and arrow, he will shoot into the left eye, and the accuracy of this gun is too poor." ”

"Rate of fire." Bi Gou didn't want to comment on whether it was accurate, this deviation was too small, and he could hit the enemy just like that.

Guo Ziyi began to operate quickly, pulling the hammer, lowering the air closure rod, loading bullets, lifting the air closure rod, opening the medicine pool, pouring the medicine, combining the medicine pool, and firing.

Repeatedly, with each shot, the bullet hits the target's head.

Li Yi pinched and counted the time, one minute, eleven shots, just so fast.

"Alright, guys, according to my algorithm, normal archery is called a target that can be shot at that distance in a minute, about four to five times.

With this gun, eight times when he was proficient, six times when he was relatively proficient, Ziyi didn't count, he was different from normal people.

Of course, if you practice this every day, the average person can do it more than eight times.

The point is that everyone has seen it, it's easy, just a few steps.

It is not very easy to use on rainy days, unless you have an umbrella, otherwise the medicine pool that ignites the gunpowder will lose its effect when it encounters water.

Wait, wait until I find time to make mine mercury, it's too dangerous and troublesome, I don't want to make it.

It consumes a lot of sulfuric acid, nitric acid, and alcohol, and mercury is not worth much, and it will rumble if you are not careful. ”

Li Yi didn't shoot the gun, he explained that he couldn't shoot it with the same gun, but the gun was designed by him.

Bi Gou and the others listened patiently, the steps were simple, and looking at the gun didn't seem complicated.

"Li Yi, this gun is easy to imitate, if the Tubo people get it......" Song Jing frowned, afraid that others would easily get it.

"Good imitation? How can it be a good imitation? Do you know how many parts there are?

You see that there are few parts on the outside and many on the inside, and a spring alone will exhaust the Tibetan craftsmen.

There are also steel pipes, I don't say it, Tubo can only use cast iron.

They don't know the ratio of gunpowder, it's all granular gunpowder.

Rifling they will pull? They don't understand what the door and the front sight are for, and I ...... now."

Li Yi talked about the difficulty of manufacturing this gun, and the warhead of the bullet is a technical job.

The Mineer bullet made of lead was similar to the bullet he used to use to shoot birds.

The difference is that airsoft guns use such lead bullets to be propelled with gas, and there is no need to add something.

The current one-piece bullet has a pointed cork, and after firing, the cork fixes the lead bullet to become larger, and then perfectly combines with the rifling, spinning and flying out.

"Got it?" Li Yi asked.

A few people blinked, understood, very powerful, not easy to imitate.
