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!

Three thousand years ago, gods and Buddhas disappeared all over the sky, and the inheritance of practice was broken. It was not until the ancient civilization was destroyed that spiritual energy recovered. Ten thousand races took advantage of this to invade.

Five hundred years later, the human race gradually rose up and began to fight for control of the land of China, and counterattacked all races.

Three hundred years later, Fang Yi, the Lord of the Great Dao, slaughtered all clans, destroyed all the heavens, stepped out of the myriad realms, and fought against the Dao of Heaven.

In desperation, Fang Yi sacrificed blood to eight hundred small worlds, reversed time and space, and was reborn nineteen years old.

In this life, he wants to live a more relaxed life, perfect his Dao Xin, and conquer the Dao of Heaven again.
