MTL - One Punch Man: Eight Strange Skills at the Beginning - Chapter 235

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.

Lin Tantan was a die-hard fan of Ye Xiao, the most powerful person in the apocalypse. After her death, she went to the beginning of the apocalypse more than three hundred years ago. Her first wish was to protect Ye Xiao and his team, who were still relatively weak at this time, so that he would not go back to the original path of his teammates dying, and finally blowing himself up among the zombies.

Of course, to love someone is to love his CP together. Her second wish is to focus on protecting Ye Xiao’s vice-captain, so that these two lovers can open their hearts to each other bravely, and spend a happy life together. No more regrets.

Ye Xiao found that whenever he talked to Old Bai, that very powerful but also a little weird little girl always looked at them and smiled like an aunt. So, what was she laughing at?

After a long time, Ye Xiao blocked the little girl in a corner, kissed her forehead, and successfully saw the little girl instantly turned into a screaming chicken, and laughed in a low voice: “Who told you that Old Bai and I are a couple?”

Lin Tantan: “!!!”

What should I do if I want to fall in love with my idol?
