I, Am a Living Yama, Empress Advises Me to Stay Calm - Chapter 172

Roan transmigrated as an FBI investigator.Several years later, a journalist interviewed the world-renowned detective Roan Greenwood and asked,“What made you persist in solving cases for so many years?”Roan tilted his head and glanced at the sports car beside him, the villa behind him, and the beautiful woman inside the villa. He smiled slightly and said,“Well, the bonus after solving the case.”“What?”

Is magic really a wish machine?

No! In a universe where magic actually exists, the ultimate nature of magic must be as simple and beautiful as the laws of physics.

This is the story of a mass-produced magic warfare tool man who learned the ultimate nature of magic.

But so what?

Just as a bird can fly without understanding aerodynamics, so a wizard does not need to understand the ultimate nature of magic to use magic.

Knowing the ultimate nature of magic does not mean that the tool man can become a great magician.

But the desire for knowledge is human instinct, and curiosity is the first driving force of human civilization. Humans hope to understand the inner workings of magic, even if it is supposed to be unreasonable.

An inquiry into the ultimate nature of magic, without any justification!

The story in the book takes place in an age where steel dances with gunpowder.

Here, muskets are in the ascendant, armor is still the protagonist, military theories are changing with each passing day, and innovations in systems and craftsmanship are emerging one after another. And this world has one more thing than ours: magic.

The world is undergoing earth-shaking changes, and no one can stay out of it.

- Description from novelbuddy

[Warning: r18, smut, MC does morally questionable things][Disclaimer: The Gods and Goddesses in the story's world have absolutely no relation to any Gods that are worshipped in the real world. The purpose they serve is also entirely different.]~Even if you're someone who typically doesn't enjoy works with smut, I request you to give this novel a chance (provided you're 18 or older of course). It would be awesome if you could at least read Volume 1 before deciding whether or not this is your cup of tea.~This is an action + kingdom-building story where the MC and his kingdom (Realm) are metaphorically powered by his lustful acts.The story begins with Hiro's (the MC) transmigration into a magical world. At first glance, this “World” might look quite similar to many other fantasy worlds that you've come across on your reading adventures. Status screens, levels, classes, gods, kingdoms, elves - all that good stuff.But it will soon become clear that this World has its own “Rules”. These (mostly) game-like Rules will bring out unique character interactions. They will be what differentiates the World in my story from other similar fantasy worlds.Now about the characters - specifically the main character.The MC (Hiro) will be thrust into the role of Ruler in the new World right off the bat. He starts with a bottom-tier, barebones realm and makes his way to the top.I'm going to say this right away - Hiro is a deeply flawed character at the start. Yes he might be overpowered and good at getting things he wants, but that does not make him flawless.Hiro has glaring emotional flaws at the beginning. He is intelligent but not in the emotional sense. He is lustful but not truly loving. He is apathetic towards death (both of himself and of others).The women who surround him will also have their own problems, both internal and external.As the story progresses, it won't just be the MC and his realm growing in power.Hiro and his harem will also mature emotionally. Hiro's character growth will be a slow, grueling burn. It isn't going to be a smooth straight line from point A to point B.But when it finally does happen, it will be worth it.That's all from me, your author. I hope you enjoy the ride.P.S - Power stones, golden tickets, gifts, adding this to library, reviews, comments, paragraph comments - all these things help immensely and are greatly appreciated.Thanks and Enjoy! :)

Birth rates are decreasing. Hope is vanishing. The world has gone gray.Humanity, drifting in quiet collapse, receives an email.Every person on Earth. Simultaneously.The Aegis Mandate.Disguised as a cosmic aptitude test, it triggers The Incident of Separation—a global psychic cataclysm that erases identities, wipes memories, and divides all survivors into three factions: Law, Neutral, and Chaos. Overnight, cities become battlegrounds. Apartments become dungeons. Ordinary people become monsters—or the ones who hunt them.Ragnar Vhagar was just a loner university student. Now, thanks to a system he didn’t ask for, he’s a newly minted Demon King, locked in a crumbling apartment with goblins under his sofa and a glowing soul crystal next to his frozen peas. His new job? Build a deadly domain, defend it from invading “Heroes,” and somehow level up fast enough to not die.Alongside him is Isabelle Thorne, a razor-sharp warrior of few words and one very sharp sword. Their reluctant alliance, born in blood and snark, evolves into trust—and maybe something dangerously close to affection—as they rise together through the layers of the game-like world they’re trapped in.With each conquered domain and defeated boss, Ragnar realizes the truth: the dungeons aren’t meant to crown a winner. They’re meant to break the players. The Law faction wants control. The Chaos faction craves destruction. But Ragnar? He wants something they’re all too afraid to say out loud:Freedom.In the ruins of Kanta’s ogre stronghold, Ragnar and his misfit warband take their biggest step yet—claiming a kingdom, unifying a fractured system, and preparing for what comes next. The Heroes are watching. The gods are stirring. The world is watching a war.And somewhere deep beneath it all... Ragnar is rewriting the rules.
