Elf Tensei Kara no Cheat Kenkoku-ki - Chapter 12Book 3: -2: The Gates of Hell

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.

Le Yao became a cannon fodder wife for the *sshole CEO, Nangong Jue. As she cherished her life, she quickly signed the divorce agreement and walked away. After she got far away from him, she let herself fly free. Strongly determined to succeed, she returned to school and became the most beautiful scholar on campus. To turn her life around, she started cooking delicious food. When she started to live-stream her cooking sessions, she became a popular cooking goddess. Plus, she even taught line dancing to older ladies, becoming the sassiest dance goddess as she twisted her hips.

Le Yao was speechless. She unintentionally let herself fly free a little too quickly, huh?

Nangong Jue: “It’s fine. No matter how far or fast you fly, you’ll never fly out of my palm.”

A bunch of big shots who want to hug, kiss, and pamper the heck out of Le Yao: “…”

Le Yao: “…”

“Boss, Madam wants to play a role in a movie.”

“Invest in a movie and make her the lead role!”

“Boss, Madam wants to be a model…”

“Bring international models for her to use as a stepping stone!”

“Boss… Madam wants to be a singer…”

“Buy 1 million copies in advance!”

In her past life, Bai Qingyan hurt the man who loved her. He looked at her lovingly as he fell to his death and she realized she loved him all too late. To live a life once again, she vowed to grasp this happiness with him. No longer will she regret.

“Who calls my name? You aren’t worthy! Also, it’s time to pay off the debt and enmity incurred from the past. Are you ready?”
