'Zizizi'

Mars are everywhere.

A piece of high-strength metal gradually took shape, and in Li Hanyang's hands, it gradually became a complex and precise part.

"If you want to get it, get a semi-automatic flintlock pistol. The most primitive flintlock pistol, with a fuse, needed an open flame to ignite it before it could be released. There is no market for this kind at all, I need to use a firing pin structure. ”

"The trigger pulls the firing pin, strikes the inside of the chamber, igniting the gunpowder, creating air expansion pressure to push the bullet. But what material should this firing pin use to generate high heat by striking the metal?"

Li Hanyang muttered and drew a few strokes on the drawing.

There was a plate of gunpowder that had been prepared on the table, and Li Hanyang took some of it and put it on a piece of steel, holding a hammer in his hand that was also made of steel.

After a moment's hesitation, he gently smashed the steel plate covered with gunpowder with a steel hammer.

There was a 'ding', but the gunpowder was not ignited.

Li Hanyang muttered: "The power of this hammer has exceeded the power of the spring firing pin, but it has not ignited the gunpowder. The steel collided with each other, but the heat generated was still not enough. ”

Sad face: "The structure has been designed, so what internal firing pin material should be used?"

“......”

After continuous experiments, Li Hanyang carried out long-term trial and error research.

Trial and error is also a discipline in science. Because you don't know the properties of some materials, you can only experiment one by one, and if the experiments are recorded, you will accumulate a lot of knowledge. And until you try out the most successful combination of materials, that's the right answer.

Of course, the cost of trial and error is very high, and you first have to have that capital to try.

But money is nothing to Li Hanyang now. The double dragon was on fire for a long time, and it was not replaced until the three dragons came out, and Li Hanyang had already made enough money. And if you don't dare to cultivate, the money will accumulate.

"The only thing that didn't try, the impact between the darkiron, didn't produce high heat. Tried too many metals these days. Now only one last combination has not been tried, and the collision between steel and darkiron. If it doesn't work this time, there will be no way in the short term. In the Lingyun Sect, all the possible metals that can be bought are already here. ”

Li Hanyang looked at the steel hammer in his hand, looked at the dark iron plate below, and hesitated. In fact, there is no such material as dark iron on the earth, and Li Hanyang can't tell what kind of material it is, at least there is absolutely no such metal on the periodic table. Maybe it's a specialty of this Xianxia world.

"If that doesn't work. Do I need to use a flint firing pin? If I use a flint firing pin, not only will the gunpowder become a consumable, but the firing pin inside will also become a consumable. In this way, the consumer will feel troubled, the cost will be too great, and the flintlock pistol will become extremely chicken. ”

"Do you want to use alloys? But I don't know anything about the metal elements of this world, how to match alloys?"

“......”

Looking at the Xuantie plate below, shaking some gunpowder on the Xuantie, Li Hanyang didn't have any expectations, and smashed it down with a hammer.

There was a loud bang. Li Hanyang was so frightened that he squatted on the ground.

At the moment when the steel hammer and the dark iron came into contact, the gunpowder was suddenly detonated, and a terrifying energy and fire burst out. The dazzling eyes were extremely dazzling, and even Li Hanyang's eyes were a little flowery at one point, and he couldn't see anything clearly.

"it! it!"

"Darkiron and steel, and this wonderful chemistry?"

“......”

Li Hanyang excitedly smashed the black iron with a steel hammer again, this time without gunpowder. 'Ding' touched slightly, but saw the sparks flickering.

Li Hanyang saw something more excited than a spark.

This hammer went down, and the gunpowder residue left on the black iron plate before was shaken and flown away.

You know, after the gunpowder has been burned, there will be residues sticking to the object. But Li Hanyang hammered down, and those gunpowder residues jumped up.

"No...... Not sticky?"

Li Hanyang muttered and blew lightly on the black iron plate.

'Whew'

The powder and particles that had been burned by the gunpowder flew out with this gentle breath. The dark iron plate is smooth as a mirror, still shimmering with metallic luster.

"Damn. Don't stick!"

"What kind of element is this dark iron made of? The gunpowder burns on it, and it doesn't even touch! I haven't found it before!"

"This ...... This means that if you use black iron for the chamber, there is no need to clean the chamber after each shot. With a shake, all the remnants of it came out. ”

"Found a baby!"

“......”

He never expected that such a chemical reaction would occur when steel and dark iron came into contact. This dark iron is also a little too amazing.

Li Hanyang excitedly removed the face towel that wrapped his mouth and nose, and redrew the drawing of the gun chamber structure on the drawing with his eyebrows.

At this time, Xu Xiuqi came to the door: "Hanyang, something is wrong." ”

"What's the matter?"

Li Hanyang did not stop writing.

Xu Xiuqi told everything that happened at the outer gate, and said with a sad face: "The Three Intercepted Dragon Factory uses the price of 5 spirit stones a month, and the people in our factory are about to be hollowed out. If this continues, there will be no one in my Hanyang factory. ”

"Five?" Li Hanyang raised his eyebrows and said with a smile: "How much does he earn with a bow, excluding the cost? If my guess is right, Liu Yu can only earn a dozen spirit stones with a bow, right? He is willing to spit out five?"

Xu Xiuqi sighed: "It seems that Liu Yu is preparing to bleed heavily in order to crush us." ”

"Bloody, I'm sure those who were poached by him won't get a penny. ”

"Why?"

Li Hanyang sneered: "You don't understand the status of the outer disciples in the hearts of the inner disciples. It's as lowly as a pig and a dog. If it weren't for the fact that I had a good head, Liu Yu would not even be able to pay the outer disciples, and he might even directly enslave a group of free laborers. You see, those who change jobs are going to be doomed in the end. ”

Xu Xiuqi sighed: "But even so, our Hanyang factory has no income recently." The business was all gone. Is your new product good? Now we can only rely on new products to survive. ”

"Survival?"

Li Hanyang sneered, poured a pinch of gunpowder into a jar, and casually threw the burning half of the candle into it.

'Boom', but I saw a half-meter-high fire coming out of the jar. The huge energy directly shattered the iron can.

Xu Xiu's mother screamed strangely: "What is this." Such a handful of fingernails burst out with such terrifying energy. ”

Li Hanyang chuckled: "This is a new product. Its existence is not to continue life, but to completely change an era. ”

's confident and calm appearance made Xu Xiuqi completely convinced. This aura belongs to the absolute contempt of high-ranking intellectuals, which no one can imitate.

Late at night, when Li Hanyang walked out with a strange-looking metal stick, Xu Xiu opened his eyes in a daze and asked, "This stick is a new product?"

Li Hanyang looked at the first flintlock pistol in the cultivation realm in his hand with a smile, and smiled confidently:

"Do you want to know how horrible it is?"

As he spoke, he poured gunpowder from the bowl into the chamber with a spoon......
