Muyu was holding a flintlock in his hand, currently shooting at a moving target in the distance. The reason why he picked up the flintlock was because he wanted to set an example for these people. He wanted to let the other cultivators who had gotten their hands on the flintlock know that if he could put down ordinary magic tools and use a flintlock, what else can't you guys use?
But to be honest, Muyu really liked guns because they didn't require any spiritual energy to control. All you had to do was aim and pull the trigger. Even though pulling the trigger required some spiritual energy, it was much less than controlling a magic artifact.
Moreover, although this fire gun looked unremarkable, its real use was not small at all because the first attack of this gun was the same, which was equivalent to a full-force attack of a late dujie stage expert. Even he, a master of the soul separation stage, could not achieve such an attack power.
