Zhou Yili, an outstanding graduate of the Heartless Path, was bound to a System in exchange for cultivation. His mission was to save the side characters sacrificed in tragic romances. In a fictional setting, the youngest son of a demon-hunter clan elder falls into a tragic romance with a fox spirit. After driving the clan leader to his death, he forbids the killing of demons and lives with the fox spirit. Zhou Yili becomes an orphan adopted by the clan leader, a promising young demon hunter. His junior protects the fox spirit, eyes bloodshot. "I don't care if she's a demon or a human. I only know she's my wife. Does being born a demon mean she deserves to die?" Zhou Yili says, "Well, if you want, you can die with her." In a post-apocalyptic world, a kind-hearted protagonist secretly helps his zombie lover evolve.

You could make a specimen out of him~" They say whoever marries the legitimate eldest daughter of the Yongning Marquis's household will become Crown Prince, so the three princes spend every day scheming to win her favor.
