Reborn as a Demon Cultivator, Starting off by finding a Zombie Planet

Chu Xuan transmigrates to the Cangxuan world and becomes a demon cultivator of the Wuji Sect. Cultivating demonic arts involves siphoning the essence of heaven and earth and extracting the essence of all things. To become a supreme demon lord, one must slaughter countless beings. However, killing is intolerable to the human race's celestial will, and the Wuji Sect is destroyed by the orthodox sects. In a moment of desperation, Chu Xuan accidentally acquires a blood mirror that can transport him to an apocalypse-ridden zombie planet. He is astonished to discover that this place is a paradise for demon cultivators!
