The next morning, Li Yan and Master Niu went to the test booth with him, and Li Zhong and Master Mu had already arrived.

Li Yan greeted everyone and introduced Master Niu to everyone first.

"Master Mu," said Li Yan: "This Master Niu is a veteran in artillery making. You must cooperate with each other in the future."

Master Mu nodded and said, "It's long time since someone knows what we know. It's all about the things we made from half a bottle of water. I don't know how much time and materials will be wasted."

Then he bowed to Master Niu and said, "You will be responsible for the affairs in the artillery workshop in the future. I will take care of you."

Master Niu quickly bowed and said, "Don't be polite, I'm here to be a master. Let's cooperate with each other and make useful cannons."

Li Yan also smiled and said, "Master Mu, don't be too careful. Master Niu is a technical supervisor, and you are also the supervisor of the artillery workshop. However, we cannot be self-consistent. We have better methods and techniques. We still need to use them. Don't worry about the time of work and materials. Our goal is to make a cannon that is powerful and light and durable."

"General, I really want to be virtuous. After all, Master Niu has made artillery before and is more experienced than me." Master Mu quickly explained.

Li Yan smiled and waved his hand, and said firmly: "If you don't say this, you should just be the supervisor with peace of mind. You should do your daily operations. In terms of technology, you communicate with each other, and that's it."

Master Mu didn't know how to say anything else. He didn't care about this supervisor, he just forced himself to do it. Since Li Yan still asked him to keep it here, he had nothing to refuse.

Li Yan said, "Let's go, let's take a look at the cannon first."

Everyone came to the two cannons that were already installed on the cannon stand. In fact, others had seen it a long time ago, but Li Yan and Master Niu had never seen it.

Li Yan looked at Huang Chengcheng's cannon body, with thin front and thick back, and the position of the gun mouth was slightly thicker, which made people feel comfortable. He said to Master Niu: "Master Niu, come and see, how about it?"

Master Niu looked at the two cannons and said in surprise: "It looks a bit like a red cannon, but it's a little smaller."

Then he reached into the muzzle, touched the inner wall of the muzzle carefully, and nodded and said, "Well, it's not bad, the inner wall is quite smooth."

He took another brush from the gunner's hand, reached it inside and tried, and said, "It should be the same thickness, and it is also straight."

Then he looked around with the cannon twice, frowned and said, "Isn't it a bit thin?"

Li Yan explained: "It should be possible. The Frankie cannon we used is not as thick as this one."

Blacksmith Zhou took a long iron clip with a piece of burnt red charcoal on it.

Master Niu waved his hand and said, "Forget it, I won't see it anymore. You have seen it, so you probably can't see the problem. Let's launch it."

Li Yan also nodded and said, "Okay, let's all retreat and start loading and testing the shooting. Whether it can be done depends on this."

Wang Renjie immediately stepped forward and ordered: "Prepare to load."

"Wait a minute," Li Yan called the gunner and ordered: "Try it with the maximum charge. Don't use the small medicine bag at this time. It's okay. It will explode me during the battle."

Wang Renjie replied: "This gun is three inches and the Frankie we use. The medicine bag used is 100% more than the maximum medicine bag of the Frankie gun. If there is no problem, slowly test the amount of the medicine and range of the fire."

Li Yan was satisfied only then, and then retreated to the distance with everyone behind the earth wall.

The loading hand put the silk gunpowder bag into the muzzle, and the other loading hand used a push rod to push the gunpowder bag to the bottom. The third loading hand put the shell in, and the pushing hand continued to push the shell to the bottom. One igniter used a thin wire to penetrate the fire door, pierced the gunpowder bag a few times, and then extended a very long lead in. The second igniter ignited the lead with the fuse on the fuse rod. After that, all the gunners took the tools and ran behind the earth wall on the other side.

The lead was burning quickly, with a faint smoke. After the gunners were hiding behind the earth wall in the distance, the lead was ignited near the fire door.

With a "boom", a stream of white smoke came out of the muzzle. Then, a projectile was seen flying in the air and heading towards the predetermined target area. However, the shell had already flown through that area and was still flying. Until it hit the wall seven hundred steps away, with a rumbling sound, the wall was broken into a big hole.

"Hiss" everyone took a breath of air. They didn't expect the cannon to have such a long range. The shells were flying in the air. Without bounced on the ground, they flew out more than 700 steps, and they could even collapse the thick brick wall at once. The power was imagined.

Li Yan immediately ordered: "Send someone to go outside to see if anyone is injured."

His cavalry immediately rode around the gate.

Li Yan and everyone came around the cannon and admired it around the cannon.

"Not bad, not bad." Li Zhong said with satisfaction: "If you look at it from this point of view, the maximum range should be 800 steps. Grape bombs can hit 300 steps. If there are ten such cannons placed on the front, even the cavalry can't rush."

Li Yan touched the tail of the cannon and found it a bit hot. He shook his head and said, "The loading speed is not as fast as the Frangian cannon. If two cannons are in one group and they will be fired in turn, it might be better."

"Then there are so many artillery pieces I want." Li Zhong frowned and said.

Li Yan looked down and found that the fire door was not vertical, but was drilling diagonally towards the muzzle. He asked in surprise: "Who thought of this fire door?"

Blacksmith Zhou bowed and said, "It's me, this may cause less air leakage."

"Yes, you did it right!" Li Yan praised: "In the future, artillery will use this technology. Gunpowder will push the projectile forward, and the gas leaks backward will be less than the vertical ones. In this way, you will be given ten taels of gold first, and your salary will increase by ten percent in the future."

"No, no." Zhou Blacksmith quickly waved his hand and said, "It's just a small idea. Suddenly I thought of it, it's not worth anything."

Li Yan waved his hand and said firmly: "You don't want it, it doesn't mean that others don't want it. Every progress requires countless new ideas. As long as this idea is appropriate, you will be rewarded. In the future, it will become a fixed example. Anyone who has outstanding technical contributions must be rewarded according to the size of the contribution. You must also get this reward, and you must set a good example for future generations."

Blacksmith Zhou smiled and said, "I have so much to say, so I'll be disrespectful."

Everyone smiled and congratulated Zhou Blacksmith. Then the second cannon began to test the shooting, but it moved back more than a hundred steps, and two high layers of soil bags were piled up on the wall.

With a "bang", the projectile flew out less than three hundred steps and landed on the ground. Everyone knew that the cannon was useless and it was wrong to hear the sound.

Li Yan looked at the cannon that was still emitting white air with regret. Although it did not crack, there was indeed a leak.

Master Niu smiled and said, "It's already very good. Two cannons have become one, and the level is already quite high."

Li Yan thought about it, so he thanked Master Mu and Blacksmith Zhou and others: "Thank you for your hard work these days, and give you an extra month of food and salary."
