Despite the psychological preparation, it still surprised everyone when it was tested.

The scarecrow that was the target flew straight into the sky, and was torn to pieces by the scattered shrapnel. The arm-thick wooden pole was directly cut into several sections.

Ao Canghai's mouth was open enough to fit six eggs, and Man Gui was also shocked. The grenade made of ceramic is already very powerful, and this grenade made of iron is even more powerful.

Although their brains are not very good, they still know which is harder, ceramic or cast iron. Because the explosive power of gunpowder was insufficient, only ceramic shells could be used. If you use cast iron, you won't be able to blow it up at all.

But the explosive power of this nitrocellulose is really amazing. Cast iron shells produce more explosive fragments, increasing their lethality by more than one level at once.

Forty or fifty meters away, Li Xiao clearly felt the shock wave generated by the explosion. The feeling of stopping one's breath and even one's heart is all too familiar.

"I said Brother Xiao! You can tinker with this thing! And that's just a grenade, if it's a thirty-pound shell. I'm so good, I'm terrified to think about it! Ao Canghai said excitedly.

With this weapon of mass destruction, the ability of enemy cavalry to charge will be greatly reduced. This is only a three-pound grenade, if replaced with a thirty-pound shell. That effect!

I can't imagine!

"Now that the explosion has become more powerful, we will no longer produce thirty pounds of heavy shells. The thing was so heavy that the trebuchet could only throw a hundred or so steps.

Now that the power has increased so much, I think it is possible to make ten and fifteen pounds of ammunition. After all, the weight is reduced, and the distance of the projectile is much farther away.

In the past, our trebuchets did not even dare to approach the city walls. Because those bows and arrows on the city wall can shoot a distance of more than a hundred paces. Now we have ten and fifteen pounds of ammunition, so that our trebuchets can attack the walls where their bows and arrows can't shoot them.

Besides, even in field conditions, trebuchets can be thrown farther. If you are very willing, you will fire one or two more rounds, and with this kind of powerful ammunition, firing one or two more rounds will also cause great damage to the enemy. ”

"If the ammunition is reduced to about fifteen catties, the power should not be small. And fifteen pounds of things, trebuchets can easily throw out two hundred steps. In this way, when the enemy cavalry rushed within the firing distance of the muskets, they could fire at least three or four rounds. Even if the Tartars come with a thousand cavalry, Lao Tzu can easily deal with it. Ao Canghai grinned.

Man Gui was a little depressed, his favorite was cavalry. Now seeing that the cavalry can be restrained like this, it is not a good feeling in my heart.

Li Xiao smiled and didn't speak, the same weight of clay ammunition was much larger than iron ammunition. The wind resistance is naturally different, so iron ammunition can be thrown farther, at least three hundred steps is no problem.

"In the past, you asked Lao Wu to buy back those weird-looking stones, and everyone chewed their tongues. Now it's time to see who dares to chew their tongues. Grandma's! Lao Tzu loaded the gun and tried it to see if he could fire the projectile farther. Ao Canghai's eyes were full of excitement, he wanted to know very much what such powerful gunpowder was used on firearms.

"It's better to find a gun and fix it on an iron frame for testing." For the sake of safety, Li Xiao admonished.

Unexpectedly, it was such a sentence that saved Ao Canghai's life.

The steel used to make arquebuses is the strip steel made by Li Xiao, which is a low-end product in steel. This is also something that can't be helped, this year, one is no equipment, and the other is no technology. Tinkering out of strip steel is already Li Xiao's limit.

Such an arquebus made of steel can be loaded with black powder. It can be filled with high-end goods such as nitrocellulose, which is obviously a little unsuitable. Ao Canghai was inexperienced and filled nitrocellulose according to the standard of gunpowder.

The only consequence can only be a bore!

"Boom!" With a sound, I don't know if the projectile flew out or not. The barrel flew out! The whole gun was scattered within a radius of 20 meters, and the arquebus experiment became the scene of a large rollover.

"Good boy! Fortunately, I listened to your son, otherwise whoever would have been killed would have died. "Ao Canghai, a guy with thick nerves, his face is also as white as a piece of paper.

"See! This thing is powerful, but it is also very dangerous. That's why I built the factory so far away from where people lived. Now I have made a rule here, and in the future no one will do what I have set by the rules. I found that I played twenty boards at a time, and then I found that I cleaned up the bed and got out. Go to Lushun and plant crops! ”

Seeing that everyone was stunned by what had just happened, Li Xiao took the opportunity to set up a rule. Nitrocellulose is no joke, and once it explodes, the consequences are unimaginable. Phi Island is so big, I can't tell if it will affect the residential area.

"No!"

Ao Canghai and Man Gui were the first to take the lead, and the rest of the people followed Qi Chengnuo.

Inatomi Yunao wears a kimono and pulls clogs on his feet to collect parts one by one. It can be seen that the old devil is very sad. Because he made the arquebus, which is the best in Japan. Now in the face of this new type of ammunition, it cannot withstand the explosion. This is definitely a slap in the face for a legendary gunsmith like him.

Li Xiao looked at this old devil with sympathy, and put aside national feelings. The devil is very respectable in terms of professionalism. Inafu Youzhi usually censors the barrels made by Zhao Tiezhu very strictly. Out of ten barrels, it's good to have one pass the old devil's test.

Although Zhao Tiezhu often scolded and complained in his mouth, Li Xiao firmly supported Inatomi Youzhi. The quality of firearms is directly related to the lives of soldiers, and it is absolutely not allowed to be sloppy.

The fisherman picked up a piece of loose parts and looked left and right. "It's a matter of iron!"

"Of course it's the iron, but it's the stone." Zhao Tiezhu said a little unconvinced.

Li Xiao looked at the two guys with his hands behind his back and didn't speak, only peers were naked hatred. This sentence not only applies to the cross talk world, but also to any industry.

"If you can forge this kind of iron, your level can be considered okay. But the old man can forge a better one! Why don't you try it? The old fisherman looked at Zhao Tiezhu, looking like a grandmaster.

Li Xiao's eyes lit up, the old fisherman was originally a blacksmith. This old guy has just arrived on the island, and it is time to stand up. He said that he could forge better steel, but he probably didn't say anything.
