Feng Mang - Chapter 214

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.

"Locke transmigrated into an era where everyone had Battle Beasts. Daemons were rampant and humans were forced to build walls around their dwellings while depending on Beastmasters to keep those monsters at bay.

The end of the world is coming, the world has undergone great changes, and everything has changed. Plants, animals, and even insects, as long as there are living things, have mutated.
Become more powerful, and even evolved supernatural abilities, such as chickens and ducks that can fly to the sky, such as cats and dogs that can breathe fire.
But only humans, without any obvious changes, seem to have fallen from the top of the food chain to the bottom of the food chain overnight.
Any creature that can open its mouth to eat can treat humans as food.
But fortunately, this world has not completely killed humans. Gradually, humans discovered that they had the ability to cultivate compatibility with other creatures.
As long as it has a high degree of compatibility with some powerful mutant creatures, it can be used for its own use to achieve the purpose of protecting itself.
Fang He is a person who is very compatible with mutant animals, but it is also because of his ability that he has changed from the strongest to the stupidest.
Fang He, who was reborn, said, “Hmph, this time…”

Transmigrating from the Apocalypse to a technologically developed, peaceful world, Qiu Yu’s killing skills cultivated through hundreds of life-and-death situations suddenly lost their use, and even his body turned into a weak, squeamish…

Qiu Yu’s world views shattered into pieces: What the heck is an Omega?!

Qiu Yu, who knows nothing but fighting, eventually decided to become an anchor for a full-dive game—not only could he use his battle techniques to make a living, but he also didn’t have to brave leaving the house and meeting people—it was the perfect job.

However, in his first-ever broadcast, he shot an arrow straight through the heart of the e-sport circle’s verified no.1 god of war.

Mu Feibai touched the place above his heart, the corner of his mouth hooking up: Interesting… Come play professionally.

Qiu Yu rejected him: social anxiety, not going, see ya.

…And then he was sold off by his live-streaming platform to play for a professional team.

Qiu Yu: This was different from my plan!

Mu Feibai: You shot an arrow straight into my heart… baby, you still want to run?
