The flame crossbow did not crack as a whole, but the inner bamboo tube could not withstand such a violent explosion and had cracked. Apparently, the flame crossbow was useless after being used once...

"Is the barrel made of copper and iron, so it can be used repeatedly? If it is filled with more medicine, it will be more powerful?" Ye Zier is also a well-informed person, and he immediately asked the key point.

Wu Mancheng nodded and said: "It stands to reason, but the general will not have enough manpower for a while..."

Nahe Wugu said: "Then quickly mobilize people from all over the city and make five or six thousand troops. I think this is more effective than holding a crossbow. Especially when defending the city, if the enemy troops climb up to the top of the city, a crossbow will shine.

Spray in the face, and you will hit the target with every shot..." Nahe Wugu is also a veteran. He saw the range of the flame-breathing crossbow, but the spray shot was only one piece. This is used to defend city fortresses and has much stronger advantages than ordinary crossbows.

Wu Mancheng smiled bitterly and said: "Mr. Wu Gu, it is easy to hoop a few copper circles with bamboo pipes, but it is not easy to cast copper pipes and iron pipes - another Fuhuo Dan requires saltpeter. Nitrate can be used.

There are yào and yào shops for sale, but the whole yào saltpeter in Yanjing is collected, which is only about four to five hundred kilograms, and we have used it in the past three months. If we follow the old method to collect saltpeter, a place as big as Yanjing

A city can only harvest one or two thousand catties a year, but two thousand catties of medicine can reach the sky..."

Fan Wenlan saw that the crossbow had just been made. Each crossbow contained two or three liang of ammunition. It could be equipped with two thousand kilograms of Volcanic Fire Pills in a year. Five thousand flame-breathing crossbows could only be fired twice a year. What was the point?

In comparison, Shosakusi uses as many as four to five million arrow clusters to make traditional crossbows every year; no matter how powerful the flame-breathing crossbow is, it cannot fundamentally change the status of traditional crossbows on the battlefield.

Furthermore, the cast copper iron chamber tube can be used repeatedly, but it is easy to say but not necessarily easy to make. So what if a real sample is captured from the battlefield?

The iron-framed ships built by Huaidong were all dismantled and placed in Tieshan Shipyard. The structure did not look complicated at all, but the builders and the iron yard repeatedly melted and cast iron materials, but they could not make it up to standard.

The ships are made of iron bones.

Fan Wenlan admonished: "In my humble opinion, instead of rushing to build a flame-breathing crossbow at this time, it is more important to make all the generals familiar with the characteristics of the flame-breathing crossbow and be prepared for it. The flame-breathing crossbow has its own advantages.

It has its own shortcomings. As long as we have the skills to deal with them and the methods to deal with them, we don’t care how the Huaidong Army can rely on them."

Ye Ji'er was right when he thought about it, and ordered Wu Mancheng: "The general will quickly make more flame-breathing crossbows and send the engineering officers to the various armies to practice shooting. The generals must be aware of their behavior so that they will not be suddenly surprised during the battle."
