ALL-MASTER NECROMANCER

Betrayed and killed by his fellow Ninestar guild members, the powerful necromancer Cha Jinhyuk resorts to a daring soul transference. A decade later, he awakens in a new body, devoid of his former powers. With the support of his new comrades, Spirit Master Balkan and hobgoblin Haryu, he embarks on a quest for vengeance, scaling the mysterious tower once again. Only this time, he possesses the overpowered abilities of an "All-Master," enabling him to master all the occupations within the tower!
