The Cannon-Fodder Male Side Character’s Self-Cultivation

[Transmigrate into a book + System + redemption + redeeming the villain] What should you do if you transmigrate into the body of a cannon-fodder supporting male character who’s supposed to get himself killed for the male lead, indirectly causing the main couple’s tragic ending? Yun Qian’an and his beloved dog, Sanqi, die in an explosion together. He transmigrates into the body of that cannon-fodder supporting character, while his dog becomes a divine beast. All he has to do is humiliate the male lead, steal his resources, and tell his lackeys to kill him. It’s fine, it’s fine. At worst, he’ll just die again. For his and Sanqi’s happy life, Yun Qian’an diligently starts raising the male lead’s favorability and preventing him from turning evil. But why is the male lead looking at him more and more strangely? What did I say wrong just now? Why did the male lead’s corruption score go up again? He’s so hard to please. “You like her?” Xiao Chiyang asks in a chilling voice. “No, I don’t.” Yun Qian’an quickly shakes his head. She’s part of Xiao Chiyang’s harem. He wouldn’t dare entertain the thought. “Then do you like me?” Xiao Chiyang asks again. Yun Qian’an sucks in a sharp breath. What a loaded question. The male lead’s harem is right here. Should he say yes or no? “I like you. You’re my...” Yun Qian’an is about to say, “the most outstanding junior disciple,” when Xiao Chiyang silences him, with his mouth. “Senior Brother, don’t push me. You can’t beat me now.” Is this right? This can’t be right. System, help! What do I do if the male lead has gone off the rails? Yun Qian’an freezes, unsure what to do. The arms around him are holding him tight, and he really can’t beat Xiao Chiyang right now. (P.S.
