Global Apocalypse: Whose Villain Is This Powerful?

【Multiple Heroines + Slow Burn + Invincible in the Later Stages】(Sadly, the results were poor, so it was dropped...) Mo Yunxuan transmigrates into a university dorm, seamlessly taking the place of his predecessor just as he is about to open the door and head inside. But then his roommate Ye Chen, who sleeps in the next bed, suddenly comes back reborn, shouting that the apocalypse is coming. Mo Yunxuan had planned to join forces with him and conquer the apocalypse! Who could have guessed that Ye Chen's next words would be that he wanted to castrate him! To survive at Ye Chen's hands, Mo Yunxuan decides to stop being human! Campus beauty: “Boo-hoo, Brother Xuan, Ye Chen and I really have nothing going on! He's just my lapdog.” Mo Yunxuan: “Then shall we make him kneel outside the door?” Ye Chen: “Damn you, Mo Yunxuan! In my last life, you stole the woman I loved, and now you're making me a eunuch!” Mo Yunxuan slaps him: “You never even got to touch her, and you still dare say she was the woman you loved?” (The protagonist starts out weak and gradually grows stronger, so the story has a somewhat slow start. It's a gradual-growth novel, so please don't read it if that's not your thing.) (This isn't a traditional kill-everyone villain. He has inherited the villain's identity, but is still an ordinary person at heart. Please don't read it if that bothers you.)
