“这破鸟铳忒他娘的沉了！”王猛单手持着刚造好的火铳，使劲晃了晃，手臂都有些发麻。铳管粗得像小水桶，装填火药和铅弹的时候，手指头都得使上吃奶的劲儿。

他在自家后院，一个临时搭起来的工坊里忙活呢。这院子以前是家农庄，现在被他改造成了小型黑火药作坊和兵工厂。墙角堆满了硫磺、硝石、木炭，还有一大堆砸碎的瓷器罐子，是用来装铅弹的。

“沉是沉，可精度高啊！”王猛自言自语，脸上带着点得意。这可是他根据现代枪械原理，结合古代现有材料摸索出来的。枪管里钻了螺旋膛线，打出去的铅弹又圆又光，弹道稳得很。

他刚试打过，打中院外那棵歪脖子柳树，歪扭地炸了个开花，把树皮都炸掉了一块。这效果，比府城里那些老掉牙的火枪强太多了。

“光有枪还不行，得有炮。”王猛搓着两只沾满黑乎乎火药的手，琢磨着下一步的计划。鸟铳虽然好用，但射程近，威力也有限，搞定了小股敌人还行，想撼动那些大势力，得有更厉害的玩意儿。

他取出一张画着简陋图样的纸，比划着。那上面画着一个大号的铁桶，桶身上开了几个炮口，旁边还配着几个玻璃瓶，写着硫磺、硝石等字样。

“这叫‘掷弹筒’，”王猛眼睛一亮，“虽然原始，但威力绝对惊人。别看它简陋，装上高爆药，砸到人堆里，那就是一片哭爹喊娘啊！”

Privately, he was already thinking about how to improve it. According to his understanding of modern artillery, the discharge port should be designed according to the principle of recoil. The propellant used should also be richer in nitrate and fine-grained for higher explosion power. These ideas were just萌芽, he didn't know how to achieve them with the materials here, but he had to figure out a way.
