The villainess shall be mine - Chapter 2 A New World, And A New Beginning?

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.

Being given a chance and reincarnated is nice and all, yet why do I have to become that male friend who just watches the protagonist flirting with his harem?---World: Kaguya-sama: Love Is War - Hyouka ----

At the beginning, he acquired a piece of land worth billions, but Su Ming used it to cultivate crops!Row after row of cucumbers, plant after plant of chili peppers, shoot after shoot of bamboo shoots… …Everyone couldn’t understand: “Having a billion-dollar land and using it for farming? Su Ming, what’s wrong with you?”Yet, Su Ming just smiled mysteriously.Do you really think, naively, that the cucumbers I grow are just ordinary cucumbers?The joy I find in farming is something you can never imagine!

Leng Pan never expected her late-night rant after reading a book about the apocalypse to change her life forever.Frustrated by the sheer stupidity of the second female lead in the novel; Apocalypse Rebirth', she criticized her tragic death, and the character’s blind loyalty to the female lead. But when Leng Pan wakes up, she finds herself inside the very novel; as the second female lead!She realizes she had transmigrated into the novel on the day she’s meant to hand over the jade bangle with a space to the so-called “best friend” who would betray her. With only seven days left before the world falls into chaos, Leng Pan refuses to follow the script. Instead of giving up her greatest advantage, she uses it to stockpile supplies, distances herself from the scheming reborn heroine, and most importantly; fights for the love of the male lead who once died trying to save her.Armed with foreknowledge, Leng Pan will change her fate. No more being used as a stepping stone. No more tragic endings.This time, she will survive. And she will thrive, even in the apocalypse.But what happens when the butterfly effect of her transmigration changes the script? Will her plans fail to keep up with the changes or will she rise above the author’s imagination and write her own story with the man who would kill and die for her?
