It was already late at night, but Li Zhang was not asleep yet. Instead, he carefully checked the drawing he drew under the candle. He also picked up the pen next to him from time to time to correct some unreasonable aspects. Next to the drawing was a hunting rifle that had been dismantled into parts.

The iron control technology of the Song Dynasty was already quite superb, and it could even mass produce steel. The steel output in the Song Dynasty was said to have reached an astonishing 150,000 tons in the year. Seven hundred years later, Britain, which had just begun the industrial revolution, had steel output only more than 70,000 tons, which was not even half of the steel output of the Song Dynasty. From this we can see that the development of the iron smelting industry in the Song Dynasty. Of course, when Britain completed the industrial revolution, the steel output jumped to several million tons. After all, the power of industry was infinite.

Li Zhang has also seen many iron tools, such as Lu Wu and his friends, with excellent steel mouths. Although they are not as good as the cold weapons he found on the plane, they are also quite good. In addition, there are some other iron tools that are well-made, so Li Zhang wanted to try whether he could make muskets in the Song Dynasty.

Of course, although Li Zhang didn't know much about guns, he also knew that if he wanted to build a gun, the most difficult part of the technology was not the gun itself, but the bullet. A small bullet not only included various metal crafts, but also base fire, gunpowder, etc. This involved a complex chemical industry. Li Zhang asked himself that he would definitely not be able to do it, so he could only build the most primitive co-cord gun or flintlock gun.

However, Li Zhang had never seen the actual objects of the clamp or flintlock gun. He had only read pictures in some historical books. Of course, he also knew that their principles were very simple, but he didn't know much about the structure inside, so he took the shotgun on the plane and it would definitely not be possible to copy it, but it was still okay to make a reference. After all, the principle of the gun has not changed much since its invention, and the structure is similar, it is nothing more than a firing device at the back and a barrel at the front.

Of course, the principle of a gun is simple, but it is not easy to design a qualified gun. Fortunately, the mezzanine and flintlock rifle are relatively primitive, and Li Zhang also has a hunting rifle as a reference, so the design went very smoothly.

Originally, according to the development of guns, the initial appearance should be a comb-lock gun. It was not until hundreds of years later that the flintlock gun was over. Because the flintlock gun has too many shortcomings, it not only needs to be lit in advance, but also fears wind and rain, and shooting is also very troublesome. The flintlock gun does not have this disadvantage. The structures of the two are actually similar, but the idea of ​​igniting gunpowder is different.

It is precisely because of the various shortcomings of the flintlock gun that Li Zhang directly started designing the flintlock gun directly. The so-called flintlock gun actually changed the flint to flint, and used flint impact to generate sparks to ignite gunpowder. This not only greatly simplified the shooting process, but also did not need to use flintlocks. It was still possible to shoot in rain and windy weather. Therefore, after the flintlock gun appeared in later generations, it quickly replaced the flintlock gun. It was not until the emergence of the rear-loading gun that the front-loading gun, such as the flintlock gun, was completely removed from the stage of history.

Li Zhang continued to modify until midnight, and then he fell asleep in bed with satisfaction. He woke up the next day and continued to modify some key places countless times until he felt satisfied. In addition, he also thought about finding some information from the computer, but unfortunately there was no information at all. There was some information about smelting steel, but ordinary people could not use it as a gun.

After several days of modification, a flintlock gun designed by Li Zhang finally appeared on the drawings. The discarded paper used for modifications was thicker than the palms. Li Zhang burned all of these drawings, so as not to be obtained by those who are interested. Then he took the drawings to find the judge Liu who was in charge of the blacksmith.

"Newly steamed meat buns!" Li Zhang found Judge Liu who was urging craftsmen to work, and then stuffed the basket in his hand into his hand. During this period, he often brought some food to Judge Liu. Speaking of which, Judge Liu came here alone, with no one to take care of him. He usually ate big pot meals like craftsmen, and was smoked and burned in the blacksmith shop all day long. He was also black and thin, and looked no different from a craftsman.

"Oh, thank you so much, Brother Li. I haven't eaten yet." Judge Liu was not polite to Li Zhang. He took the basket and took out two buns, and handed the rest to the craftsman next to him. As a result, the nearby craftsman rushed up and was snatched up in the blink of an eye. No one left was snatched away.

Li Zhang had long been accustomed to this situation. Judge Liu was not from the imperial examination, but a very rare official transfer. He even worked as a blacksmith before, but was promoted to Judge because of his outstanding performance.

Judge Liu is different from Lu Wu's judge. The three departments have a Salt and Iron Department. The Salt and Iron Department has seven cases. The chief in each case is the judge. Judge Liu is the Iron Casino judge in one of the seven cases, in charge of gold, silver, copper, iron, cinnabar, carbon, tin, drum casting and other affairs. Originally, he sent a seducer to take charge of the matters in the imperial tomb, but he did not expect that the seducer was involved in the case of Lei Yungong's embezzlement. He is still locked in the Kaifeng Prison prison. He could not draw out any other people for a while, so he had no choice but to go into battle personally.

"Brother Liu, how is the construction of iron tools going forward? Is it still tight to urge the imperial tomb?" Li Zhang looked around and then asked with a smile. When Judge Liu first came some time ago, people sent to urge the imperial tomb every day. Judge Liu was so angry that he almost cursed, but in the past two days he obviously felt that his temper had improved a lot.

"I worked overtime some time ago and finally finished the work of the death-hunting ghosts in the Ministry of Works. I can finally take a breath in the past two days." Judge Liu replied while gnawing on the buns. He was from the bottom and had a rash aura when he spoke and did things. This was one of the reasons why he dared to quarrel with generals like Hu Yan Shouxin before.

"That's great. I'm a little bitch here. I want to ask Brother Liu to help me see it. I wonder if Brother Liu has time?" Li Zhang asked again with a smile.

"Oh, what?" Judge Liu couldn't help but ask in surprise when he heard this.

Li Zhang immediately took out the drawings and handed them over to Judge Liu and said, "This thing needs to be made by blacksmiths, but I don't know if our blacksmiths from the Song Dynasty can be made by us?"

Judge Liu also took the drawing and looked at it. It was a split drawing of the flintlock rifle. Each part inside was drawn clearly, and even the size and materials were marked. This made him look at Li Zhang in surprise. He probably didn't expect that Li Zhang, who was young, would draw such detailed drawings. This drawing was even more detailed than the drawings he had seen in the Zhou case.

"This... could it be a firearm?" Judge Liu looked at the drawings for a long time, and finally asked Li Zhang with his beard.

"Brother Liu, you have a good look. Can you tell that this is a firearm?" Li Zhang couldn't help but look at Judge Liu in surprise when he heard this, because the flintlock rifle drawing only has a structural diagram, but its function is not indicated. Moreover, even a firearm has not appeared during the Song Dynasty, and the use of firearms is not widely used. Most people may rarely associate the things on the drawings to the firearms.

"Haha, I'm not to be hiding from Brother Li, our Salt and Iron Department has seven cases, including the Zhou case, which is mainly for the famous military weapon making, as well as military weapon workshops, bow and crossbow courtyards and other matters. I have worked in the Zhou case for a while before, and the workshop under my subordinate is responsible for making firearms, so I am not unfamiliar with firearms. Moreover, there are places where gunpowder is poured on your firearms. The pipe in front is similar to the bamboo tube of a rocket, so I thought of the firearms." Judge Liu replied with a smile.

During this period, the Song Dynasty had already begun to use firearms to defend the city. For example, the poison smoke ball recorded in "The General Yao of Wu Jing" is actually a special shell. It is not only poisonous, but also explodes after landing. However, this shell is fired with a device similar to a stone thrower, rather than a cannon from later generations. In addition, the rocket mentioned by Judge Liu is actually an arrowhead driven by gunpowder.

"So that's it. No wonder Brother Liu thought it was a firearm. I just don't know if the blacksmiths could make this thing?" Li Zhang asked again. Although the structure in the flintlock rifle was simple, the requirements were still very high in some places. For example, the spring required elastic steel sheets. Although the Dasong Dynasty could produce steel, he didn't know whether this kind of steel could be produced.

Judge Liu looked at the drawings carefully again, then touched the short beard below and said, "There are some places that are indeed a bit complicated, but not particularly difficult. If Brother Li can trust me, why not leave the drawings with me and I will help you with some advice, and then draw a few craftsmen to try it."

"That's great!" Li Zhang immediately slapped his thigh, but then he said with some concern, "This will not delay your affairs with Brother Liu, right?"

"It's okay, there shouldn't be any big work these days, and I'm quite interested in firearms. To be honest, there are people in the Zhou case who are studying firearms, but unfortunately, there are not much progress. If your firearm is successful, maybe I can still make some contributions." Judge Liu smiled again and said.

However, even though he said that, Judge Liu actually had little hope for this firearm, because in his opinion, Li Zhang, who was young at most, made this thing out of fun, was far from comparable to the gunpowder craftsmen in the military weapon workshop. The reason why he promised to make this thing was actually to repay Li Zhang's favor.
