Didn't I Decide to Lie Flat? How Did I End Up Ascending the Throne?

[Ruthless and decisive + reborn + farming novel + political intrigue] After transmigrating to a parallel world as the crown prince, Xiao Jing discovers that his father doesn't care for him and his mother doesn't love him. He holds the title of crown prince in name only. Faced with baseless accusations from the Second Prince and the indifference of his supposed father, he simply throws down the crown prince's seal and walks away. He has no power or influence and can't become emperor anyway, so whatever happens, happens... After leaving the palace, Xiao Jing starts a booming business with his personal eunuch. Before long, even the court officials have become his customers... Another late autumn arrives, and the great general brings Xiao Jing a garment and drapes it over him. “Your Highness, it's getting cold. You should put on another layer.” “Wait, why is this garment yellow? And why does it have a five-clawed golden dragon on it?”
