One has to slaughter countless beings to rise as a supreme demon lord. However, such killing was intolerable under the heavenly Dao of the human race. Consequently, the Infinite Sect was annihilated by the orthodox sects. In desperation, Chu Xuan stumbled upon a Blood Mirror, which allowed him to travel to a post-apocalyptic planet overrun with zombies! He realized that this place was a perfect sanctuary exclusively for demonic cultivators! If he dared to sacrifice a million humans, the heavenly laws would strike him with thunder and burn him to ashes. But if he sacrificed a million zombies, not only would he face no disasters, but he would also be showered with golden blossoms, enveloped in glorious light, and blessed with merits!
