However, I didn't care about it, because I knew what this world was waiting for ahead.In the near future, the Ruvens Empire will be mired in chaos, and in order to survive it, I decided to quietly sit out in the manor enjoying a luxurious life. Everything went according to plan, until one day I made just one fatal mistake.A year after my rebirth, I accidentally found a wounded commoner in the forest. Out of pity, I decided to take her in and kept her. We lived together until I found out that this was the main villain who was supposed to die at the end of the novel. But because of my interference, the plot of this damn book continued with me!I have to run now! But where...?!After all, this crazy woman is now stalking me.— Where are you going, lady?— I… just went out for a walk.— Take a walk? The border of the empire is not the best place to walk. Let me walk you back.With the sword in her hand, I didn't have a chance to refuse.

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.

At some point in the 21st century, the Christian God stopped listening to the prayers of humanity. Monsters with colossal strength and endurance began to emerge and humanity entered its darkest period.

Zhu Tong was born in a wealthy family, but the pampered young master suffered from a serious cleanliness addiction, and there were so many things that even God can’t stand it, so he was given a sickness and even coughed three mouthfuls of blood.

The day before his death, he was inexplicably bound to a system.

The system told him that he was actually a cannon fodder villain in a danmei novel who humiliated the heartthrob protagonist and suffered the consequences. If he wanted to survive, he had to find the only one in the novel, the white moonlight, who was not attracted to the protagonist and get full favorability from him.

In order to find him, Zhu Tong changed schools.

The new school was located in a remote small county with eight-person dormitories, a canteen for big pot meals, and only one public toilet in a teaching building.

Zhu Tong: In order to survive, he will endure!
