[A slow-burn romance, with a gradual relationship development and mostly story-driven plot. Older love interest. If this isn't your thing, feel free to skip.]
At the moment Shen Yu argues with his girlfriend, he accidentally falls into an alternate cultivation world.
He is supposed to follow the established plot, protect his master, who is destined to die a tragic death, and rewrite that ending.
But every scheme and every step leads somewhere unexpected, and the story's course slowly slips completely out of control.
Theme: Love yourself
