I Heard My Junior Brother Went Off the Rails [Reborn]

[A new novel is looking for preorders~ "Do I Really Have to Be Emperor? [Book Transmigration]". The blurb is below.] Meng Wanhe spent his entire life living for others. In the end, he even died to save all living beings under heaven, but he never regretted it. Given another life, what Meng Wanhe hated most was that he hadn't been reborn while his master and senior brother were still around. But no matter what, he still had to shoulder the burden. For the sake of Qingxu Mountain, he was still that big senior brother who cared for the world and would face death without hesitation. Only, something had changed. Could someone tell him how Ning Xi, the person he had always protected and believed was destined to save all living beings, had ended up joining forces with demons and monsters? Ning Xi at first: I'm going to strangle Senior Brother! Ning Xi later: I'm going to strangle Senior Brother! Meng Wanhe bit his lip. "Strangling me around the waist won't kill me." Meng Wanhe wanted to kick the man who kept pawing at him off, but Ning Xi just smiled brightly. "If Senior Brother dares move, I'll kill them all. Didn't Senior Brother want to die? Here's a better choice: please me, and I'll stop." Meng Wanhe: "...You wicked fool!" Ning Xi sealed Meng Wanhe's lips with his own. "Then I'm a wicked fool belonging to Senior Brother alone." Meng Wanhe thought Ning Xi was just fooling around, since his junior brother had always been so carefree. But now... His junior brother seems to have gone off the rails. Anyone there? What should I do?! A cold, repressed, abstinent shou x a domineering, shameless gong who turns dark later on Both are reborn. At first, they can't stand each other and are disappointed in one another. Later, they fall in love while trying to kill each other. The shou has always loved the same person.
