I'm Already the Demon Ancestor, Yet You Still Want Me as a Stepping Stone?

[Invincible] [Feel-good and satisfying] [No heroine] [Revenge] [Decisive and ruthless] [Spiritual qi revival] Guardians stand in the sunlight, protecting the darkness the sunlight cannot reach. One night, they wake up. The light has turned to darkness. Darkness runs rampant in broad daylight. When the boundary between humanity and the uncanny vanishes, the guardians roam the darkness, still struggling to protect their last home. The Demon Ancestor, a third race between humanity and the uncanny, becomes a guardian through a twist of fate. A hundred thousand years later, Ye Xiaotian becomes the Grandmaster of Demonic Cultivation. Just as he reaches the pinnacle of sainthood, he is unable to unite light and darkness because of the many demons in his heart. He is reborn on the day he was framed, and must resolve those inner demons one by one to attain the Great Dao. His heart is a cauldron that devours resentment. Each measure of resentment it consumes dispels one inner demon! Reborn, he finds his biological parents treating him like trash and his adopted brother using him as a shield against evil. "You ungrateful brat! Pour all your power into your younger brother. He's the chosen one!" "Big Brother, you can't leave this family. I still need to take all your fortune for myself." "We don't have a younger brother who likes to steal. You may be related to us by blood, but we don't acknowledge you." Ye Xiaotian: "I'm already the villain destined to be the chosen one's stepping stone, and you still expect me to play along?" Heh heh heh... You're all nourishment for this Grandmaster! Yet overnight, his enemies and family undergo a complete reversal. The uncanny descends, and humanity becomes a race on the brink of extinction... Guardians, bring light to the depths of darkness!
