The Necromancer is amassing troops like crazy in the apocalypse

The genuine Necromancer, with countless skeletons, becomes a ruling sovereign. After obtaining the Double Doors, Wu Heng discovered that his world was overrun with zombies. Plan A failed, and thus began the implementation of plan B for survival. Wu Heng chose to become a ‘Necromancer.’ Summoning undead is forbidden in this alien world? The post-apocalyptic planet is full of potential soldiers. Impossible to survive in a zombie-filled world? Then let me live and learn skills in this alien realm. Hence, an undead army armed with modern weaponry made its debut in this world. A calamity engulfs the world, a million skeletons rise. The Dead Bone Dragon, Undead King. (Double Doors + Necromancer + Magic + Fantasy World + Undead Catastrophe.)
