All Master Necromancer

A necromancer named Cha Jinhyuk is betrayed and killed by members of his own guild, Ninestar. To survive, he performs a risky soul transfer. Ten years later, he regains consciousness in a new body, but without his previous abilities. Supported by a companion known as Spirit Master Balkan and a hobgoblin named Haryu, he seeks revenge and returns to the enigmatic tower. This time, he has the ability to become an "All-Master," allowing him to learn and use all the different roles available within the tower.
