Chapter 550 (1/2)

Soon, in the admiration of a group of blacksmiths, Ning Xiao made three two meter long straight gun tubes, but the rifling inside was the most important. It was difficult to make the rifling accurately by forging technique.

Ning Xiao can only forge the basis of yin and Yang rifling with some of the techniques in Zhen Zi Jue. Then he gets a cutting tool and starts to cut rifling according to the rules.

Whether it's cutting the barrel or the barrel, Ning Xiao's technology is speechless. This kind of antiaircraft gun generally uses gradual rifling, but Ning Xiao has replaced it with mixed rifling, that is, rifling whose winding angle changes with the change of winding. This kind of rifling has no twist angle at the root of the barrel near the chamber, and the twist angle increases with the increase of the twist distance. If the gun barrel is unfolded, this kind of rifling will be partially curved and mostly straight. The advantage of this kind of rifling is that the initial velocity of the projectile is larger, the kinetic energy is more, it can fly for a longer distance, and the adaptability to high chamber pressure is relatively good.

However, it is clear that the rotation speed of the warhead is not high enough, and the armor piercing performance is very weak. Therefore, it is generally used on the long barrel cannon howitzer to kill the enemy by explosion.

Now what Ning Xiao needs to do is to be able to play higher, and no armor breaking ability is needed, so the mixed rifling is the best choice.

After pulling the rifling of the third gun barrel, Ning Xiao saw a group of craftsmen squinting and looking inside the gun barrel cut in front of them. They were all amazed.

In fact, Ning Xiao is very proud of himself. In his previous life, someone told him that he could cut the rifling of the gun barrel by hand. He absolutely killed the man with one slap. The gun barrel is completely different from the gun barrel. This length alone is enough to make you shake when cutting the rifling in the depth. There is no way to cut the rifling by hand.

But in this life, relying on the strength of being a spirit defender and the hand stability trained by forging, Ning Xiao successfully completed this impossible task, and also felt that it was not very difficult

Tiechen didn't know the function of the rifling. They just marveled at Ning Xiao's excellent workmanship. When they first saw the rifling, they just thought about how to form the line inside by forging, but they didn't expect that they could make special tools for secondary cutting.

However, after seeing the production process of Ning Xiao, they all know that even if they think about it, their skills are not enough to cut such smooth lines, which will shake and lead to line deformation.

Seeing that Ning Xiao put down his tools, Yan Linghan said with a smile, ”master Ning, all the things you need have been forged?”

Ning Xiao took a long breath and nodded with a smile: ”yes, all the things needed have been made!”

Yan Linghan looked at the strange things full of ground, shook his head and said with a smile, ”but master Ning, I really can't see what these things are. Can you explain it?”

”Ha ha, you don't need to explain. You can see it when I put it together.” Ning laughs and goes to the middle of a pile of parts and starts to assemble quickly.

Soon, as like as two peas, the three guns stood on the ground. It's just that the muzzle is not 45 degrees to the sky like a normal antiaircraft gun, but 90 degrees to the ground.

Obviously, Ning Xiao changed a little when he was making it. After all, he only needs to fight up to the sky. If he hits high enough, then vertical to the ground is undoubtedly the best way to reach the highest level.

This magical scene once again shocked Yan Linghan and a group of blacksmiths. They did not expect that these parts could be completely combined into this picture.

Yan Linghan didn't understand what the cannon was and what it was used for, but he felt extremely exquisite.

This is also normal, any high-quality weapons, are in line with the aesthetic process, do not know the power of the case, only feel good-looking and handsome. If a weapon is ugly, it is not a good weapon unless it is deliberately made.

”How wonderful! Although I thought that these parts can be combined with each other, I didn't expect that they can be combined so thoroughly. How complicated is this Yan Linghan stroked the gun body with a trace of warmth and exclaimed.

Tiechen's craftsmen are speechless. Looking at Ning Xiao's eyes, they seem to be looking at idols and superstars! In a word, Tiechen has seen some silver craftsmen, but he can bet that none of them can make this thing in front of him!

No, I'm afraid they can't assemble even if they give them the parts!

”Ha ha, this is the cannon I mentioned earlier. I just want to use this thing to launch the collected breath into the air.” Ning Xiao patted the antiaircraft gun beside him and said to Yan Linghan.

”Launch into the air?” Yan Linghan had an idea, pointed to the long gun tube and said, ”is it from this hollow tube?”

”Yes, you are very clever.” Rather smile to nod to smile a way.

”Haha, it's nothing. There's only a gap here. Of course I can guess.” Yan Linghan was a little embarrassed by Ning xiaokua, and then asked, ”what about the power? Does it compress the spirit power, and then suddenly burst out to launch things?”

”No, it's used...” Ning Xiaozheng is ready to say gunpowder, but just said a few words, but suddenly stunned, Lingli compression?

Seeing that Ning Xiao was stunned, Yan Linghan was also stunned, and then carefully asked: ”that, master Ning, did I say something wrong?”
