I Use Artillery in the World of Cultivation

Cultivators cultivate their lives, weapons, and immortality, but I took a unique step. I practice weapons, swordsmanship, and body training, but I feel that my biggest fear comes from lack of firepower. Regardless of whether it's a demon, demon or fairy, it can all be killed with one cannon. Why do you have an outer body, a law of heaven and earth, and I have tanks, cannons, and humanoid mechas.
