"And what did the gunpowder ignite?" Zhang Nan continued to ask.

"Naturally, it's on fire, ah...... I see, it's flint, right? Li Er said with a smile.

"That's right, it's flint to ignite gunpowder, so that more projectiles can be shot in less time." Zhang Nan said.

Just as a few people were talking, Bing Zhi also took Li Er, Zhang Nan and Liu Bing to twist and turn in the Tiangong Department, until Li Er was dizzy, and the few people finally arrived at the place.

"I said that the soldiers, the road of your Heavenly Works Department is inevitably too tortuous, after I have walked around, I can't even guarantee to continue to walk here again from the outside." Li Erdao.

Hearing this, Bing Zhi also smiled and said: "Back to the emperor, this thing was designed by Mozu himself, unless he is familiar with the art of Qimen Dunjia, it is really difficult to come out of it." However, Mozu also marked some hidden symbols on the road to help find the way, otherwise the villain would not be able to find it for a while. ”

"Haha, it seems that this Tiangong Department is really the safest place in the world, and even Qimen Dunjia is used." Li Er also laughed out loud after hearing this.

Although Bing Zhi and Zhang Nan didn't figure out where the laughter of this thing was, Comrade Li Er laughed, and they didn't seem to be able to say it if they didn't laugh, so they could only laugh awkwardly with Comrade Li Er.

Bing Zhi quickly took Comrade Li Er to their testing ground, and then picked up a primitive flintlock pistol from his desk that had not been beautified and handed it to Li Er.

"Your Majesty, this thing is a pistol."

After Li Er took the pistol, he also showed a look of surprise and said, "This thing is much bigger than I thought." "After all, Zhang Nan's Desert Eagle is like a child compared to this sinister pistol.

The pistol that Bingzhi gave to Comrade Li Er was not only long, but also very heavy, and the handle part was originally made of wood, so that it would be much more convenient to use, but Bingzhi directly made the handle out of metal.

It's not that Bingzhi doesn't know how to reduce weight, it's just that when it was first manufactured, Bingzhi used a machine tool to use it easily, so he directly used metal, anyway, this thing is just the first generation, as long as it can ensure the power.

As for aesthetics and practicality, let's leave it until the power reaches the standard.

"Oh? What is the trough under this tube for? Li Er observed very carefully, and soon discovered that there was a small groove under the barrel of the firehead pistol that Bing Zhi had.

"If you go back to the emperor, it will be used to load the knife." Soldiers to the road.

"Loading knives?" Li Er asked suspiciously.

"That's right." After Bing Zhi finished speaking, he didn't know where to find a slender knife and handed it to Li Er.

Li Er also took the knife curiously and tried to install the knife on the slot, Li Er didn't have much effort to install the knife on the slot reserved under the barrel.

Now this pistol has become a combination of hot and cold weapons.

"It's also ingenious." Li Er nodded with satisfaction and said.

"This rifle has to be reloaded with gunpowder after every projectile is fired before it can be fired a second time, so in order to prevent the enemy from having the problem that the gunpowder has not been loaded in front of him, the villain also installed a knife on it, if the gunpowder does not work, the knife can still be used." Soldiers to the road.

"It's good, but this thing can't be made a little smaller, after all, this thing is still a little inconvenient to carry." Li Er scratched his head and said.

In fact, Li Er also wanted to have one of these things, but now what Bing Zhi gave him obviously only met the combat standards, not Comrade Li Er's carrying standards.

"This is naturally possible, the villain can make this thing a little smaller." Bing Zhi patted his chest and reassured.

"Alright, alright, show me just how powerful this thing really is." Li Er said, and handed the pistol in his hand to Bing Zhi again. Bing Zhi nodded, knowing that Comrade Li Er was going to let him do a demonstration.

Bingzhi did not hesitate, and skillfully took out a small paper bag and was about to tear it open with his teeth, but was stopped by Comrade Li Er.

"What is this thing?" Li Er curiously clicked the small paper bag in his hand with his hand.

"If you go back to the emperor, this thing is a projectile loaded with a rifle, and in order to facilitate reloading, the projectile and gunpowder are put together." Bingzhi replied.

"Oh? It's a clever idea, is that what you came up with? Li Er said with some surprise.

After hearing this, Bing Zhi scratched his head embarrassedly, and then said: "This is not it, this is what Lord Zhang came up with, originally this projectile and gunpowder were separated at the beginning, first to fill the gunpowder, then to load the projectile, and then use a stick to make them solid before they can be launched, but Lord Zhang came up with this method, which saves a lot of time and effort, and the time that used to shoot two bullets can now be fired three rounds or even more." ”

In fact, of course, this thing is not Zhang Nan's original, and this is also copied by Zhang Nan from the existing history of the rifle. After all, this thing doesn't involve anything in terms of scientific and technological leapfrogging, so Zhang Nan doesn't care.

When the flintlock pistol was first invented, the modern cartridge with a shell had not yet been invented, and they were all front-loading flintlock pistols. The gunpowder of the musket was wrapped with paper with the warhead. In order to prevent the gunpowder from getting wet in the rain or getting wet, it was wrapped in paper coated with butter or lard.

When loading, the toughness of the paper coated with animal oil is improved and there are no edges to tear. So biting open is the quickest way.

After biting, part of it is poured into the bite chamber to make ignition gunpowder. The rest is poured from the muzzle as a propellant. Finally, the round warhead is put in and hit with a throughbar. A tong bar is a long iron bar with a notch at the end. After striking with a throughbar, the bullet undergoes a slight deformation and is tightly integrated with the chamber of the gun, so that it will not roll or fall out of the chamber.

Zhang Nan directly copied this method as it was.

"Okay, show me the power, if the power can reach my heart's expectations, I will be rewarded, of course, if I don't reach it, I will also be rewarded." Li Er said with a smile.

It seems that Li Er is still interested in the weapon of the Sui Gun for ten minutes.

As soon as the soldier heard that he was rewarded, he nodded violently, and then happily bit open the package of the bullet bag, and then poured the projectile and gunpowder into the barrel of the rifle.
