A global catastrophe has arrived, with monsters rampaging everywhere. To combat this, the world becomes digitized, and everyone at age eighteen awakens with a combat or support class, leveling up by defeating monsters. Lü Yan awakens with the weakest combat class, Necromancer, but gains a class auxiliary system, allowing him to awaken a second time into the hidden class, Necromancer Lord. Despite initial doubts and the perception of Necromancers as weak, Lü Yan's journey is one of growth and overcoming adversity.
