"Loading the lead pellet and gunpowder into the same paper tube, tearing the paper tube when loading, and stuffing the gunpowder and lead pellet together with the paper tube, can not only ensure that the gunpowder is filled with sufficient weight, but also increase the charging speed."

Fan Jingwen picked up a firearm and thought about it carefully for a while, and the more he thought about it, the more he felt that this method was effective, and he couldn't help but start experimenting at that time.

He first found a piece of paper, then brought a powder pot and lead pellets from the soldiers guarding the city next to him, and then began to pack them according to Chongzhen's idea.
