Overpowered Archmage Doesn't Hide His Talent - Chapter 31: How about trying the spell once?

Transmigration is the total rage of novels nowadays, and if the main character isn’t careful, they get swept up into the bandwagon, so this is a story from another continent. Magic? —— of course the main character won’t know how to use it, but what about knowing how to use electricity? Dou Qi? —— the main character still doesn’t know, but is inner power more strong? Beautiful women? —— of course the main character has them, or else there wouldn’t be anything worth reading in this novel. How many? —— that question’s quite good, if I told you everything, what would you read for? An honest warning to the female readers and your tastes, it is a harem novel, don’t read it if you’re not interested. A stern warning to male readers and your tastes, um, it’s like a breath of fresh air.

- Description from Novelupdates

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.
