It has been more than two months since Li Chen came back from Didao County, and it is about to be the New Year, which is already Li Chen's second New Year in this world.

The raging snowflakes fell flutteringly, and the bitter cold wind blew through in gusts. The setting moon in Xianyang City was no longer above his ankles, and the pedestrians on the street couldn't help but shrink their heads and tighten their cuffs when they walked on the road.

"Whew, whew, whew."

"Go, go, go."

There was a constant sound in a factory in the deepest part of Lijiazhuang, which was almost the most heavily guarded place in Xianyang. It can even be said unceremoniously that even if the palace is guarded, it may not be as heavily guarded here.

There is a stove and bellows in the middle of the factory, and a craftsman is pouting and pulling the bellows. And the big bull on the stove was holding the tongs in one hand and the hammer in the other, striking the red-hot copper. Da Niu's craftsmanship became more and more refined, and it didn't take long for a square and square copper block to be beaten into a cylindrical copper pillar by him.

In just two years, Daqin's technology has advanced by leaps and bounds. Lijiazhuang has become a small village and has become the scientific research base of Daqin, where almost all the top skilled craftsmen of the entire Daqin are gathered. Now, they were studying Great Qin's first musket, which was a New Year's gift from Li Chen to the First Emperor.

What Li Chen wants to build is not a flintlock pistol, a front-loading gun like an arquebus, but a firearm that was active from the late Qing Dynasty to the end of the Anti-Japanese War in his previous life, and the old sleeve was made in Hanyang. The manufacturing process of this firearm is not very complicated, in the special period of the previous life, many small folk workshops can make firearms that can be fired. Today's Li Jiazhuang can mobilize all the power of the entire Great Qin, and Li Chen can get some cross-era tools from the earth. In this case, the manufacturing process of Lijiazhuang was no worse than that of the small folk workshops of that era.

"Master Hou, do you think this is okay?"

Da Niu stopped what he was doing, and the cylindrical copper stick was removed from the cutting board and asked.

Li Chen took the vernier caliper next to him and stuck it on the copper rod, and it was exactly the same from top to bottom. You have to admire the craftsmen of this era, their hands are rulers, even more accurate than any ruler.

"Alright, go to the poison dragon drill." Li Chen said nervously.

The poisonous dragon diamond is the name given by Li Chen, in order to pay tribute to the youth that passed away in the previous life. This dragon diamond is in the collection of a military museum in Earth's space, and is said to be one of a set of hand tools in the collection of a master who specializes in hand-making firearms in an oil-rich country on Earth. In the previous life, there were all kinds of lathes and all kinds of precision machinery, and this kind of hand tool seemed to be a little idle and painful. But when Li Chen found this set of tools, Li Chen directly thanked him eight times his ancestor.

This set of tools directly satisfies Li Chen's dream of firearms, and the reason why Li Chen didn't make guns before has no other meaning, that is, he really looks down on front-loading guns. Under the shortcomings of the slow firing speed of the front-loading gun, the inability to use it on rainy days, and the inability to use the barrel of the iron roll for a long time, etc., compared with the Qin crossbow, a long-range weapon that the Qin army is now equipped, it does not have a full advantage.

And this set of tools directly raised the military level of Daqin by more than one grade, once the first rifled gun is finalized, then it will not take long to be mass-produced. After all, Li Ce is not Jia Yueting, and the dream of firearms is not just drawn on paper.

Fix the cylindrical copper rod on the table and aim the drill bit at the center of the cylinder. This is a manual drill with a handle on the top of the drill bit. Da Niu kept holding the drill bit in his hand and pulling the handle on it.

The hardness of copper is far less than that of this unknown drill bit, and the bull pulls the drill bit hard, and the copper rod is drilled into a copper pipe little by little.

"Boom, boom."

In this season of dripping ice, the big cow only wears a short sleeve. The muscles on his arms are exposed, but he is still pulling the drill bit. Li Chen could believe that this should be the most powerful time for Da Niu, even when Wang Li asked him to drive piles, he didn't use such strength.

It took three hours to drill the rod into a perfect barrel. Needless to say, Da Niu's craftsmanship has not moved at all in the past three hours. By the time the barrel was drilled, the hand on which he pulled the drill had been ground down, and it was dripping with blood.

Li Chen picked up the barrel of the gun and looked at the light, only to see that there were thread-like lines in the barrel. This is rifling, to say that this master's tool is good, the pattern on this drill bit corresponds to the rifling of the barrel. The barrel of the gun looks like a perfect fit both from the outside and from the inside.

In the previous life, some handicraft workshops could draw rifling by hand, although this era of Daqin was in poor conditions, but it couldn't stand Li Chen is hanging, with the help of the most advanced tools in the previous life, he naturally made the first barrel of Daqin.

The barrel of the old sleeve is definitely the most technical thing in the whole gun, in fact, except for the barrel, the rest of the parts are not in the eyes of the Great Qin craftsmen. In the previous life, the so-called top handicraft masters, their craftsmanship may only barely pass in the era of Daqin. You must know that Daqin's assembly line manufacturing process is thousands of years ahead of the so-called developed Western countries in the previous life. In this day and age, what you make is not a fraction of a centimeter good. Then your head and head are estimated to be a millimeter off.

Li Chen looked at the parts on the table greedily, holding the vernier calipers and measuring them one by one, although he knew in his heart that these craftsmen would not make any mistakes, but he still wanted to measure, this may be the right to be capricious.

"Okay, sloppy, I'll see the finished product tomorrow."

Li Chen said to the big cow. Now that all the parts are in place, it's just a matter of putting them together. For Da Niu, this matter is simply Zhang Fei eating bean sprouts, a piece of cake.

"Bang."

Soon the assembly of the gun was completed, and Li Chen gently pulled the trigger, feeling the sound of the hammer. Although there was no live shooting, Li Chen could feel that this was a good gun, which was a man's intuition. Just like when you see a long-legged cutie on the street, although you don't have a test drive, you can tell at a glance that this is a good car, which is also a man's intuition.

"Big bull, how long will it take for this gun to be mass-produced." Li Chen asked.

Da Niu looked at Li Chen, then at the gun in his hand, and then said with the arrogance of a craftsman: "It is estimated that it will not work for a lifetime." ”

"Speak human words?" Li Chen said angrily.

"That's all there is to it, how can you let me mass-produce." Da Niu glanced at Li Chen and said. Hou Ye seems to have become his way of relaxing pressure, after all, people with skills are quite willful.

Li Chen felt that this kid's consciousness seemed to be a little low, didn't the old saying say, if there are conditions, you have to go up, and if you don't have conditions, you have to go up.

"If you don't have enough tools, will you mass-produce tools first?"

"Big brother, will it be imitated. Will the cottage be you, won't you learn from penguins? ”

As soon as Li Chen finished speaking, Da Niu's eyes lit up.
