Leon was a robotics engineer with a bright future—until he was run over by a military truck and killed on the spot. But death wasn’t the end. Thanks to a cosmic glitch and to an idiot, Leon wakes up in a new world, reincarnated as the son of a minor noble family guarding the wild frontier of a massive Empire. With his intact mind, enhanced brain, and a world begging for progress, Leon sees opportunity everywhere—one that he will grab for sure.But not everything will go smoothly. Monsters come over in the winter, the Empire monopolizes magic and technology, and society clings to barbaric ways. Refusing to accept the status quo, Leon decides to reshape his family’s backwater territory into a land he would enjoy living in. Armed with knowledge from his old life, modern problem-solving, and an irreverent attitude, he plans to revolutionize his territory. But in a land where magic is rare and unknown to ordinary people, he knows he’ll need more than blueprints to succeed. He will need his own wizards and witches...Hey-ho! Welcome! I thought I need to add some information to those who want to know if they should just skip it or not: First, I ain't planning to introduce world-changing, thought-provoking ideas here. It is all for the plain and simple reason of having some fun. What you need to be aware of if you need more details:- Yes, this is an isekai story. No, there are no 'cheats' or systems involved with gaining skills. He is just a guy reincarnating with a gene-modified brain, so it explains why he can remember things and be smart. That is it. Think of it as him having a perfect memory. If you perceive confidence as arrogance, you may very well dislike the MC right off the bat. He is not someone who will lay low and try to blend in when his territory is the most backward and abandoned place in a vast Empire. Where the throne is so far away, messages take months to go back and forth.- The story mostly focuses on kingdom-building stuff and slice-of-life elements, not on conquest or curb stomping others. The main conflict will be centered around wars, yes, but it won't be one guy vs. the world or something like that. Magic is going to play a big role in building up the territory, as I plan to branch out into magic technology later on. I am going to rely heavily on magic because I am mostly a fantasy writer and not an engineer.- The MC's main goal is to enjoy himself. This also means girls. So there will be a harem. Those who are familiar with my works, how I do groups, and how my characters act will know I don't like doing cardboard cutouts of characters. Most of my stories have more than one character accompanying the MC. The same will be true here, with the extra caveat that they will also be involved romantically with the MC. - The story plays out in a 1st person POV. There won't be jumping around multiple POVs; I don't like that. Only when the story requires it and the MC can’t be present by himself for some story parts.- Don't take this story seriously nor look for scientifically 100% real and codex-like solutions for problems. This is a fantasy world, a totally different culture, and with history, that is NOT OUR world! There is magic here, and the MC has a supercomputer for a brain. I think that says it all. - My main goal is to enjoy writing some whacky but real-sounding scenarios. They will be based upon feasible ideas, but I am not writing a damned textbook about thermodynamics. Laws will be bent and broken when the story needs it.- Regarding smut, there are some chapters with erotic scenes, but not every other chapter. So expect it when the mood is there in the story and not because I must cram as much snu-snu in as possible... That won't happen.- No guns. Why? Every similar story has guns. This doesn't. This has mechs and power swords. Why? Because I said so.

Aries Aime Heathcliffe. A princess from the small kingdom of Rikhill was loved by all. With her beauty that was enchantingly demure and a wise mind, she had caught a lot of attention and captured the hearts of many. One of them was the dashing crown prince of the Maganti Empire.

Overcome by the desire to have her and his interest in the land of the small kingdom, the crown prince of the said empire would stop at nothing. The knights from the Maganti Empire marched across the masses and seized the four-hundred-year-old kingdom of Rikhill.

The kingdom of Rikhill fell into ruin overnight. The crown prince left no members of the royal family alive aside from his war trophy, Aries. After suffering in his hands, Aries found the perfect chance to escape.

That was when he took her to the world summit. A gathering of each sovereign from each kingdom and empire for peace talks.

There, she met the emperor of Haimirich, Eustass Silvestri Abel Bloodworth. Overwhelm by desperation, Aries begged him to take her in. It was too late when she realized that the man she asked for help was far more cruel, twisted, and downright diabolical than the crown prince for taking her as his… pet!

EXCERPT:

With a pair of crimson eyes hovering over her, Aries held her breath. When the corner of his lips curled up devilishly, she couldn’t react fast as he swiftly flipped their position. She only realized it when she was saddling him, gazing down at Abel, wide-eyed.

“No one is above me in this empire and even out — not even the law, but look at you,” he intoned with a devilish smirk. “Staring down on me… so daunting.”

Aries bit her lip, planting her palm on her inked chest. “Your Majesty…”

“Do you now understand the power you hold, darling?” Abel carefully wrapped his fingers around her wrist, chuffed by her reaction. “Only you, Aries, may go above me and the only person in this world who can look down on me. No one else.”

He raised an arm and ran his fingers through the side of her hair, settling his palm on the back of her head before he pulled her down until her face was a palm length away from him.

“You better use this at your own disposal,” he whispered, tilting his head as he lifted it up to claim what’s his. HER.

Meet Eustass Silvestri Abel Bloodworth, the sadistic tyrant, who reigned an empire with an iron fist. With his pet, Aries’ increasing presence in his boring, dark life, he was set to kill her. But alas, every time he thought of taking her life, he finds himself changing his mind.

The more he kept her by his side, the more it got harder to dispose of her. And the more he yearned for something deeper and darker... it was driving him insane.

With a secret he was keeping from her, what would Abel do if Aries found out about the rotting truth behind the empire and the emperor? Would he kill her? Or kiss her? Perhaps cage her?

And if she found out that Abel wasn’t just a normal human, would she try to escape? Or would she accept that he wasn’t just a demon incarnate?

In a complicated world that tainted them black, was love even possible to bloom between a pet and her master? Watch as these two play the dangerous and insane game of love and lust.

Who would be the master and the pet? Who was the prey? Read to find out more.

“Gu Hangshen! Your sister stole my man, and you helped her do it! Your whole family is rotten!”“Whatever my sister owes you, I'll compensate you.”“And what will you compensate me with?”“Me.”“...”Later, he not only gave himself up as compensation, but he also came with a clingy little bundle of joy...
