Reborn as the Zombie King in the Apocalypse

In the 108th year of the Apocalypse, after more than a century of war between humans and zombies, traitors from the zombie side led a surprise attack on the zombie stronghold, Evernight City. With the fall of Evernight, the strongest of the zombie race and its Zombie King, humanity finally won the hundred-year war. But the chilling smile, as if from the depths of hell, that appeared on Evernight's face as he fell suggested that it might not be over after all.
