[Ne Zha + Ao Bing + System + Leveling Up + Feel-Good Novel + Making Up for Regrets + Ne Zha: Demon Child Conquers the Seas]
Su Chen wakes up one day to find he has transmigrated into a demon. From the start, he's trapped in a hellish prison beneath the sea. Faced with such an absurdly good starting hand, he awakens the Devouring System.
As long as he devours someone, he can obtain their skills and increase his cultivation.
Devour Deer Boy, obtain Ten Thousand Arrows in Flight.
Devour Madam Shi Ji, obtain Mystic Stone Protection.
Later, Su Chen marries Ao Run and takes Ne Zha, Ao Bing, and Shen Xiaobao as disciples. He beats up Wu Liang Xian Weng and even establishes a Demon God Alliance.
But as Su Chen's power gradually grows, he attracts the attention of the gods and Buddhas across the heavens. They won't tolerate a great demon rising in this world.
If the Buddha stands in my way, then I'll kill him!
If there's no road ahead, then I'll carve one out myself!
If Heaven and Earth reject me, then I'll devour them both!
Prejudice in people's hearts is an immovable mountain. If it can't be moved, then I'll devour it!
Who says the demon race can't produce a Great Emperor?
Many years later, people call me by this name: the Heaven-Devouring Demon Emperor!
Very pretty [laughs crookedly]
