STAFF NOTE: The author had proven ownership. RighteousEgg is the original author. I have added a pinned comment to the first chapter to show this staff note is legitimate.---Chu Xuan traversed the Mystic Azure Realm and became a demonic cultivator in the Infinite Sect. To cultivate as a demonic cultivator means to plunder the essence of the heavens and earth and seize the quintessence of all things. 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!

Shi Jin once read a book. It was supposed to be about satisfying the desire for vengeance.
