I Saved the Villain, Faked My Death, and Now He's Seeing Red

Lin Yuzhi transmigrates into a book where the villain is the protagonist. The moment he arrives, he finds the villainous male lead on the brink of death. System: Hurry and save him! He’s dying! Lin Yuzhi: But he’s the male lead! The ruler of the Demon Realm! Doesn’t he have protagonist plot armor? Why does he need me to save him? System: ...He’s the big villain. Lin Yuzhi: Give me a cheat ability or forget it. System: ...Would water-based healing work? Top-tier healing ability, top-tier combat strength! Lin Yuzhi: All right, I’m on it. Lin Yuzhi has to complete two missions to return home. Mission One: save the male lead from his bad ending. Mission Two: give the male lead a romance plotline. With his golden finger, Mission One is a piece of cake. As for Mission Two… He’s never played matchmaker before, but he’s great at bringing people together! When Lin Yuzhi hears that the princess, hailed as the “Greatest Beauty in the Heavenly Realm,” is engaged to the villainous male lead, his gossip-loving instincts kick in. This is a ready-made match! All he has to do is wiggle his fingers, tie them together with this red thread, and he can go home! So Lin Yuzhi keeps saving the male lead, while using his name as an excuse to save the “beauty.” One day, when Lin Yuzhi has no choice but to fake his death to save the male lead, the male lead’s eyes turn red. He follows him from the Demon Realm to the human world, willing to sacrifice years of his life to bring him back. When the “beauty” learns that the male lead has revived Lin Yuzhi, she immediately charges into the Demon Realm and secretly abducts him. Lin Yuzhi: What? Come on, I’m just a cannon fodder! Male Lead: You’re the only one I want. Beauty: I love you. Lin Yuzhi: I just want to go home!
