This is a fantasy world called Azeroth, where two power systems, magic and fighting spirit, coexist. Magic is composed of mysterious magical elements and is considered to be a miraculous ability to resonate with the heaven and earth and control the power of nature; while fighting spirit originates from the human body's own power potential, which is a kind of power that can maximize the body's strength through hard training. However, for a long time, there has been a subtle competitive relationship between magicians and fighters. They each developed in their own fields and formed different spheres of influence. But recently, a mysterious dark force is gradually eroding the world, threatening the survival of all living things.
