Later, He Became A Royal Healer - Chapter 119 - Making waves hei.

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.

It was the year 2169. The apocalypse finally arrived.

Global warming, zombies, nuclear war, all at once. Just one tipping point and the world itself would crumble.

Then, Nova Corp, a hegemon of the corporate world, seemingly convinced the global super powers into doing the impossible: Taking everyone online.

And they did. Everyone, poor or rich, was taken into the VRMMORPG: World Online.

A fantasy world where anything was possible. A utopia, unlike everything that the real world was.

But what was supposed to become a method of existence, became a battleground for supremacy. Companies, world powers, and the rich battled to become the greatest.

The disparity between the poor and the rich grew. There was no justice in this world. It took Darwin's words further than any other.

Jake, as poor as one could get, was caught in the rift, torn apart by the unfair system.

He was a dog of the Shadow King Guild, and even though he was absolutely loyal, in the end, the guild cut him off.

He was without an anchor and left in the cruel world. He knew no Utopia like the others.

But one day, when he opened his eyes, nothing was the same anymore.

Opening his eyes, he found himself ten years in the past. He was done being the henchman now. He was not going to let himself be used anymore.

Now, it was time for him to fight back. So what if the strongest were going to stand in his way? He was going to be unstoppable.

I’ve reincarnated as the reverse harem game’s villainess, the one and only step-daughter of the Eckart duke family.

But the difficulty just has to be the worst!

Everything I do will only lead me to death.

I must be paired with one of the main male characters from the heroine’s harem before the ‘real daughter’ of the duke family appears!

Two older brothers who always pick a fight with me on every little thing.

The insane crown prince whose route will always lead to my death.

‘I only see the heroine and no one else’s wizard, and also her loyal s*ave knight, too!

‘First, let’s take some of them which I see no hope in, out of the list!’

“I didn’t know my place up until now. From now on, I’ll live as quiet as a mouse so you wouldn’t care the slightest bit!

But why do their interests in me keep on rising every time I draw the line?!

Take you to appreciate the wonderful life in the world of film and television……
