As a cultivation genius who has achieved a new realm every two years since he was a year old, Wang Ling is a near-invincible existence with prowess far beyond his control. But now that he’s sixteen, he faces his greatest battle yet – Senior High School. With one challenge after another popping up, his plans for a low-key high school life seem further and further away…

When he first crossed over, Chen Liguo did not want to accept it.

But he quickly discovered, after he crossed, he found that all the men he met had perfect figures and eight-packs. Furthermore, these men liked him.

As a gay man, Chen Liguo was so excited he shed tears of joy.

However, the world obviously wouldn’t have such good things.

Because, just as he was drooling and about to pounce, a system appeared and told him: Buddy, sorry to let you down, but you can’t be with these people.

Chen Liguo: What if I insist?

System: Hehe

……

Chen Liguo: You trash system! Destroying my youth! Ruining my s*x life!

- 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.
