After Transmigrating into a Book as a Scumbag, I Was Reborn

Xie Yun was willing to work for the Space-Time Administration for ten years in exchange for a chance to be reborn. He transmigrated into all kinds of book worlds to fulfill other people's wishes. Now that he's accumulated 100,000 merit points, he can finally go back! At that point, he's just started college. His family hasn't gone bankrupt, his father hasn't been murdered, and his first love hasn't left him. He can start all over again. However, after being reborn, Xie Yun keeps encountering unusual things. One after another, people appear around him who look strangely familiar, yet have no business being in this world... A classmate he has no memory of looks exactly like the bodyguard from the book where he became emperor. The police officer assisting with a case looks just like the major general from the book where he disguised himself as an Alpha to enter military school. The new school doctor looks exactly like the vampire count from the Western fantasy book... All these people have one thing in common: while completing their missions, Xie Yun flirted with them like an idiot. Xie Yun suddenly feels a chill down his back and backs away from this terrifying classroom. But after a few steps, someone behind him speaks: "Class is about to start. Where are you going?" Xie Yun turns around. A handsome guy holding a lecture handout is staring at him, handsome and wicked. Yet Xie Yun can't remember whether this person was the demonic cult leader or the disciple he took in while cultivating immortality. He blurts out, "And who are you...?" The handsome guy slowly curls his lips into a smile. "Again? So there are plenty of us, then?" Xie Yun originally thought he just had to avoid these people. But gradually, he discovers that his body is beginning to show traits from the worlds of the books he transmigrated into. This is terrible. For instance, how horrifying would it be for him to develop Omega traits in the real world... Warnings: The hero is a playboy, promiscuous, and attracted to both men and women. Don't read if that bothers you. No harem. There's only one love interest (can't say more without spoilers). New novel: Defeating Magic with Science In his second year after transmigrating to the Yujin Continent, Zhou Yan discovers that he's somehow changed from an Alpha to an Omega. Even worse, suppressants, blockers, and disguise drugs haven't been invented yet. The people here are simple and respect nature. Every so often, someone goes into heat in public on the street, drawing a crowd of curious onlookers. How could anyone stand this? He's no unevolved primitive. Fortunately, he's got a good head on his shoulders, and all the advanced technology of Miyun Star is in it. A mere bottle of suppressants won't stump him. Zhou Yan believes in science. Science can solve anything. Until one day, a person in a black robe with an ugly face collapses outside Zhou Yan's home, engulfed in blue flames three feet high. It looks extremely unscientific. Zhou Yan immediately decides to drag the corpse inside and dissect it thoroughly. The black-robed person suddenly opens his eyes, and his ugly face falls to the ground with a slap. Zhou Yan stares at him expressionlessly for a moment, then calmly asks, "You don't have one of those rules where someone has to take responsibility for you after seeing your real face, do you?" The black-robed person narrows his eyes and takes a light sniff. He gives Zhou Yan a dazzling smile. "If you keep staying here, I may be the one who has to take responsibility." A beautiful madman x a sharp-tongued elite P.S. The seme and uke are both experts in different fields. In a sense, they're both all-rounders. They're both career-minded, not lovesick. Theme: Stay grounded and conduct yourself with integrity
