Save a Failed Idol's Life - Chapter 201:

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens! A scientist’s goal is to explore the secrets of the universe, and this is exactly what Leylin sets out to do when he is reincarnated. Dark, cold and calculating, he makes use of all his resources as he sets off on his adventures to meet his goal. Face? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now. You want me to help you? Sure… but what benefit can I get out of it? Nothing? Bye. Hmmm… that guy looks like he might cause me problems in the future. Should I let him off for now and let him grow into someone that can threaten me….. Nahhh. *kill*-

Alternative: Leylin is transported from an advanced technological era into a medieval world— except there’s magic. Equipped with “only” his quick wits and an A.I. chip fused to his soul, he sets out to become the most powerful magus the world has ever known. In a land divided into the Light and Dark Magi, the weak can either be cattle or disposable slaves. Only the strong can determine their lives, and only they have the luxury for virtue. Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.

When Jiang Cheng was told to return to a family that he never knew or had a relationship with, he had never expected to end up meeting a young girl, and eventually, her seemingly roguish brother Gu Fei, as a first encounter in the new city.

After her rebirth, Rita vows not to repeat her past mistakes. This time, her first priority is to stop her brother, who is about to marry into the Lopez family, from participating in the initial game beta test. In her previous life, she was deceived by this scheming brother until her dying breath. It was only at the end that she realized she was merely a villain in a male-oriented novel about a live-in son-in-law, with all the malice and manipulation orchestrated by him behind the scenes. In this life, Rita decides to change the rules of the game. She will stay in the shadows and seize all the opportunities meant for the male and female leads. By participating in the beta test and re-selecting her abilities, she systematically dismantles the protagonists’ advantages, all while making them believe she’s on their side. Rita has no intention of harming innocent people, nor is she a selfless saint. In this game, she works with the authorities for mutual benefit, all to achieve her ultimate goal—becoming the true master of her fate.

Hello, everyone. My name is Shen JianGuo. I’m a night school teacher. I mainly teach the subjects of (Marxist) philosophy and ethics. I occasionally review new policies and measures for the students. I never see my colleagues and students during the day. The training institute classrooms are all abandoned schools, hospitals, or houses. The bus number is 444 and it always appears in front of my door at 12 midnight and disappears before 5am.

What? You say I met a ghost? Impossible. As a staunch scientific materialist, I don’t believe ghosts exist in this world.

But recently I’ve had an issue to raise. Can the training institute bring the class time up a little bit? Wouldn’t it be good to start around 8pm? Though I fear nothing on earth or in the heavens, I’m afraid of going bald.
