The Black Moonlight Is a Sickly Beauty [Quick Transmigration]

[Revised version in progress] Jiang Xianchen comes from a wealthy family, is handsome and rich, but has cancer. A thing calling itself the Male Lead Rescue System finds him and says that if he enters various worlds and helps the male leads reach the top, he can extend his life. Looking at the foolish System, Jiang Xianchen unhurriedly takes off his gold-rimmed glasses. His long lashes curve slightly as he agrees. World One: [Stray rich heir, wolfdog type x Ambitious impostor, frivolous and dissolute fake young master] The System points to the boy lying in an alley, blood at the corner of his mouth, and says, "The male lead grew up far from home and has suffered a lot. Host, you need to win him over with love and save him..." Jiang Xianchen walks over to the battered boy and takes out a handkerchief, covering his hand with it before gripping the boy's dirty chin and forcing him to look up and meet his eyes. His voice is clear and cool: "You can't even fight properly. What a good-for-nothing." System: QAQ This... the mission... Later, the mission is complete. Just before it dazedly takes Jiang Xianchen away, the System sees the red-eyed boy clawing at the dirt on Jiang Xianchen's grave. It also sees its Host's calm, impassive gaze.
