Qing Cang's eyes moved to another drawing. He always felt something was wrong with this crossbow. But Wu Chaojing reminded him. "I think this crossbow seems to have fewer wheels that can be moved. This makes the mobility much worse."

Wang Zongwei echoed: "I also found that the original design might be for the sake of stability."

Only when the chassis is stable can the shooting be more accurate. With the wheels, the recoil will make the entire crossbow appear very unstable.

Qing Cang suddenly remembered the modern cannon structure, so he said: "It is possible to leave only two large wheels in front and the back seat is on the ground. This allows the angle to be adjusted, only a little stability is sacrificed, and mobility is also guaranteed."

"yes!"

Qing Cang thought of another question again. "Zou Wei, tell me how far is the range of the crossbow on this drawing?"

Zou Wei thought about it for a while, probably because he had never thought about this issue seriously. Finally, he came up with a value.

“It’s about fifty feet away.”

In ancient times, there were three or ten meters, fifty meters or more. This distance was less than half of AK47, and the better bows and arrows had a range of nearly 200 meters. Such a distance was really a bit risky as a long-range weapon. Because those who use this crossbow will be exposed to the range of the bows and arrows, unless these people are fully armed, they will risk their lives behind the crossbow.

Qing Cang murmured: "This distance is a bit short. I have to find a way to make him shoot farther. I have to ensure the safety of the warriors."

The range and the weight of the arrow are of great importance, and the power system is to increase the range from these two points.

The weight of the arrow should not be too light, otherwise the attack power will be insufficient and it will not hurt at all to hit people.

Nowadays, one soldier and one soldier are crucial to Qing Cang.

Others here don't know anything about this crossbow. This thing is not like the city rusher. It looks more sophisticated and the materials are very complicated.

And there is one person who is most qualified to give an opinion here, that is Wang Zongwei. He knows the structure well. He said: "Can we achieve the range of range by changing the materials, such as power?"

But Zou Wei, who is also familiar, raised another difficulty at this time. "The strings of the crossbow are mostly made of two tight bundles of horse hair. Its power is related to the material. If we want to find better materials in a short time, it will be very difficult."

The crossbows have been baptized by war, and these materials are the most common and can be used everywhere. It is not easy to find a substitute.

And these things are not a problem for Qing Cang. He has broader thinking and seen more things. He once saw a kind of crossbow, which was made of a pair of springs, which can provide a lot of power. If used on a crossbow, it would be a huge revolution.

But where can I get this spring? If it were in modern times, as long as I had money, I would have more springs. I am afraid I can't find it in this era. But as he thought about it, he saw the blacksmith Xu Dezhi and thought that maybe he could make it. So he touched his waist and took out a magazine.

Everyone focused their attention on his magazine, not knowing what he wanted to do.

He poured out the few bullets left inside and pulled out the springs. The inside of the magazine is composed of a circle of springs, which can squeeze the bullets to the edge.

"Xu Dezhi, come here, I want you to make a spring like this, but not as square as this one, I want to be round! Can you make it?"

Xu Dezhi took the spring in his hand and studied it for a while. He had never seen the spring and was very curious. "This thing is very magical. If you press it, it will rebound, but if you pull it, it will shrink. I think his material should be iron, so I am 80% sure to make this."

"Eighty-most enough! Captain Wang, I draw a picture and you can make a crossbow according to the picture."

After he finished speaking, he quickly drew it on the paper, and while drawing it, he introduced that "these two pieces are springs, replacing the original power material."

He drew the entire body of the crossbow according to his memory.

People don’t know how many things are hidden in Qing Cang’s head, but they just think that he can get a lot of novel things.

Zou Wei asked now: "If it is made according to the commander's drawings, how long is the range of this new crossbow?"

"It's twice as high as before, or more, and the samples produced by Captain Wang should be subject to the actual number."

This surprised everyone, especially Cao Chen exclaimed. "What? Double! That can basically be used as a cover! Let our army rush to the city gate in a blatant manner."

Everyone was in deep thought, but now everyone was excited because of Qing Cang's words. Zhang Liao also came up with an idea. "If you tie some oil on the arrow, light the fire and burn the city!"

"This idea is good. It will save you a lot of trouble if you burn them all."

It is easy to destroy, but it is difficult to rebuild, but sometimes to achieve the goal, what's the harm? In fact, Qing Cang also thought of using a catapult cart, but that thing is too destructive. If it is really destroyed, it will take a lot of time to repair it. If an enemy invades at this time, the victory will be given to others.

Finally, Qing Cang signaled everyone to be quiet. He asked Wang Zongwei: "Captain Wang, can you complete it?"

"Commander, it's OK, but I'm afraid I can't guarantee the time."

"Well, this is a question. Those who come one by one, you will dispatch the people here. How about you arrange their work?"

"Commander, those battalion commanders still need to train troops, I can't waste their time."

He still has this awareness, but Qing Cang doesn't think so.

"It's always good to be able to complete it early. All three of them have seen these two siege weapons, so it will be smoother to make it. There is not much time left for us. I hope you can build this weapon as soon as possible and then mass-produce it, the faster the better."

In addition to the three battalion commanders present, Wu Chaojing and Xu Xun could also provide some small suggestions, and Xu Dezhi and Yang Zizong must follow from beginning to end.

"Since the commander said that, I'll have to work with all my colleagues."

There are a few of these people who are on par with him. To be honest, he dare not instruct them to do things for themselves, although this is done for the entire legion.

"Battleman Wang, don't be so polite. It's all for the Chinese Army. Just give me instructions if you have any questions. Just tell me Zhang Liao's words as long as I can use them!"

"That's right, I, Cao Chen, as for the training, we will leave it to the people below, so don't worry!"

Zou Wei also came out to participate and said, "I agree, although I have just joined the Legion, this matter seems to be more important."

Such a scene is what Qing Cang is most willing to see. Everyone is comrades-in-arms. If you have difficulties, I should help you!

"Then, I'll bother you guys, the faster the better!"

"Yes, Commander!"
