Wu Heng gains possession of the Double Doors, only to find his world consumed by the undead. With conventional survival tactics crumbling, he pivots to an unconventional strategy—embracing his identity as a Necromancer. In a post-apocalyptic wasteland where summoning the dead is deemed taboo, Wu Heng recognizes an untapped resource: the infected masses themselves. Rather than flee the zombie-infested realm, he masters its dark arts, bending this alien world to his will. Armed with newfound necromantic power, Wu Heng assembles an unstoppable force—legions of skeletal warriors equipped with modern weapons. His undead army reshapes the apocalypse, turning humanity's greatest threat into an instrument of dominion. As catastrophe spreads across the globe, a million bones rise in unison. The Dead Bone Dragon emerges. The Undead King claims his throne. (Double Doors + Necromancer + Magic + Fantasy World + Undead Catastrophe)
