In the early morning, when the first ray of sunlight shone on the Shanhaiguan weapons testing site, Ao Canghai saw this new gadget!

This is a wheeled one... I can’t tell whether it’s a gun or a cannon!

Its caliber is larger than that of a gun and smaller than that of a cannon. The most special thing is that this thing has two parallel tubes. Next to the barrel, there are two huge iron boxes. Mr. Ao, who has very poisonous eyes, look at it.

I could tell immediately that it was loaded with ammunition.

"What is this? We took the train all night, just for this?" Although Ao Canghai was very confident in what Li Xiao had tinkered with, he couldn't understand the thing in front of him.

According to his understanding, the bigger the caliber and thicker the barrel of a cannon, the better. If he did not consider the loading problem, he would have liked to use a barrel as thick as a water tank. As a frontline general, especially a general who has participated in actual combat, he has a deep understanding of artillery.

I have a deep understanding of power.

In fact, large-caliber artillery no longer relies on shrapnel to kill the enemy, but relies largely on shock waves. Shock waves can shock a large living person to death. Even the clothes on the body can be blown away! There are many corpses on the battlefield.

, in fact they are all naked.

He couldn't understand the cannon in front of him. The principle seemed to be similar to the Maxim heavy machine gun. But that thing could already cover a distance of 300 to 800 meters. For farther places, it would be better to use cannons. Because it was too

If it's too far away, it's impossible to shoot accurately.

"This is called an anti-aircraft gun, with a caliber of 25 millimeters. The old fisherman told me in his letter that the theoretical rate of fire can reach 600 rounds. However, the steel we made is not good enough, so we can barely do 300 rounds. That's it.

Every time two boxes of ammunition are fired, the barrel must be replaced for cooling." Li Xiao was a little helpless.

But it is helpless. Materials science is a basic subject. Without time to accumulate research, it is impossible to achieve results. Many times, materials science research is actually a matter of luck. If you are lucky, you will make a breakthrough in one or two years of research. If you are not lucky, you will have a breakthrough.

Well, maybe I found the right formula a few days before I died.

"You have to remove the barrel of the gun after two boxes of ammunition? This is harder than serving a fucking little girl!" Ao Canghai's eyes widened. The battlefield was changing rapidly. A gun that needs to change the barrel after two boxes of ammunition. Although

The rate of fire is almost twice that of the Maxim, and it doesn't have much value.

"In all these years, have you ever changed the barrel of a gun with a little girl?" Li Xiao looked at Ao Canghai with interest.

"Let's get down to business!" Ao Canghai rarely blushed.

"This thing is not prepared for things on the ground, but for things in the sky." Li Xiao pointed to the huge and heavy airship in the sky.

"That thing? Apart from us, who else has it? Besides, that thing is so big that it can be seen from a long distance. When the time comes, the troops will disperse and stay hidden. This is what the Mongols do now. In the past, they could still rely on airships.

Kill some people. Now it is getting more and more difficult to achieve results by airship."

"Yes! What you said is all true, but the problem now is that Wu Sangui probably already has an airship. And his airship also uses a gasoline engine that is more powerful but smaller than ours."

"Gasoline engine? Is it the one used in our latest airship? Although that thing flies faster and has a lot of equipment, it is always prone to breakage. It would be good if the attendance rate can reach half."

"England also has talents. They have two universities, Oxford and Cambridge, which continuously provide them with talents. Li Yongfang said last month that they invited an outstanding person named Newton from London. This guy is very talented, although he is not yet

I don't know what he can research, but I think he will definitely be able to research something very fatal to us.

Lao Ao! The advantage on the battlefield is getting smaller and smaller, and we must be prepared for hard battles in the future. I heard that Wu Sangui is trying his best to arm the Indians. Although those gangsters are not very good at fighting, we cannot underestimate them!"

"Yes! In previous wars, rocket launchers were invincible. The Jurchen Tatars and Mongolian Tatars all stopped. But now... ah! The Mongols also have rocket launchers, and their guns even use the same bullets as ours. Fortunately,

We still have machine guns. Otherwise, I don't know what to do when the cavalry rushes over.

It was all caused by that kid Wu Sangui. If I had known this was the case, I might as well have shot him to death early." Speaking of Wu Sangui, Ao Canghai had the urge to kill people. This kid has now grown into the most dangerous person in the Ming Dynasty.

Enemy. This danger is not purely military. It is technological and economic. India under his actual rule has become the main force to compete with the Ming Dynasty.

Without the support of Wu Sangui, the Mongols might not be able to survive for even a year. The increasingly tenacious resistance of the indigenous peoples of the island countries in Southeast Asia has Wu Sangui's shadow at work behind them.

"It's useless to talk about it now, let's see the power of this thing." Li Xiao didn't want to continue talking about this topic. If we continue talking, Ao Canghai might go to Tianjin and pull Wu Xiang out and beat him up.

If such a thing really happened, Zu Dashou's face would be ugly. He was also an unstable boss. Once these two guys got into a fight, Li Xiao didn't dare to think about the consequences.

The airship in the sky flies stably at an altitude of about two thousand meters. This is the usual flying height of the airship. Generally, no weapons can threaten it at this height.

A smaller airship is towed underneath the airship, flying more than 300 meters behind depending on the wind speed.

Although he was mentally prepared, Ao Canghai was still shocked by the high rate of fire of the Double 25 anti-aircraft gun. More than a thousand shells were fired from the two large iron boxes, and a line was connected from front to back. This line shot straight into the sky, forming a line

A very dazzling light band. I don’t know how many cannonballs were hit by the airship. At first, it only burst into flames. With the strong wind at high altitude, the flames burned violently.

The huge airship turned into a huge fireball almost instantly. The fireball burned in the sky, and then fell rapidly. The height of two thousand meters was enough to throw everything back to the state of parts. A person who fell on that high ground was unconscious.

There will be a complete bone.

After looking at the telescope for a while, Li Xiao nodded. He was quite satisfied with the result. After all, it is not easy to reach this level with something just developed. Being able to control altitudes below two thousand meters provides the best for the team base.

Basic protection.

As for the most effective way to deal with airships, currently they are airships. Li Xiao plans to install this kind of dual-25 anti-aircraft gun on the latest gasoline engine airship. With a platform like an airship, the high rate of fire of this thing at high altitude is

The current nightmare of everything flying in the sky.

"Will this bullet burn?" Ao Canghai suddenly asked.

"Oh, this is an incendiary bomb specially developed to deal with airships. There is some incendiary agent in the warhead, and it is still being gradually improved. It is estimated that after subsequent development, it will be more powerful." The concept of incendiary bombs was still proposed by Li Xiao

came out.

"This is a good thing! Get me some." Ao Canghai's eyes lit up and he immediately reached out for it.

"The stuff is good, but it's also expensive. Besides, the bullet capacity of the 7.62 bullet is so large. Let me give you an idea. The copper head of the bullet is wrapped with a lead core. You ask the soldiers to break the copper head a little.

The bullet will fragment after hitting the human body.

Don't look at it. Just a little bit of lead is enough to kill a person. If you are hit by that kind of bullet, the chance of surviving is very small. Even if you survive, it is probably the kind with missing arms and legs." Damn bullets have been used before, but that

At that time, muzzle-loading guns were used, and there was no such thing as custom-loaded ammunition.

Since the introduction of fixed-load ammunition, the Ming army has only one kind of bullet, which is an ordinary bullet with a copper head and a lead core. The main reason is that the texture of copper is soft and will not cause excessive wear and tear on the barrel of the gun.
