Sword and Sorcery and Academy

A hundred years ago, a huge war broke out between the four realms: the human world, the demon world, the god world and the dragon world. Many lives perished and the world became withered and tired. A few years after the war ended, in recognition of the harm caused by the war, and in order to prevent such things from happening again, the Three Realms Academy was established, which brought together the forces of the four major realms. A few years later, Mu Yunyu came to Three Realms College. When he looked at the more than ten meters high gate of the college, he never imagined that he would come here to make a living after leaving the mercenary group.
