Shun Seijuro was just an ordinary man—25, unremarkable, and burned out by life. But when a freak accident ends his mundane existence, he awakens in a new world: Murimdan, a continent ruled by martial might, powerful clans, ancient sects, and mystical cultivation realms.

Armed with a mysterious System that uses a classic RPG interface, Shun spins his first gacha… and unlocks the soul of a legendary figure: Sei Muyang, the feared Heavenly Demon God who once fought the Five Old Monsters of the Righteous Path and died in a battle that shook the world.

Now acting as Shun’s hidden teacher, Sei Muyang guides him in secret arts, forbidden techniques, and the path of true power. As Shun begins his journey from the Qi Gathering Realm, he finds himself at the center of old grudges, political intrigue, and the simmering war between the Righteous Alliance and the Heavenly Demon Sect—now led by Muyang’s descendants.

But power always comes with a price.

Caught in the web of three rival noble families, the ambitions of an icy yet mysterious princess named Haruna, and his own slowly evolving morality, Shun must choose:

Will he walk the Righteous Path—or burn it down with Demonic Flame?

It was the first thing Shun felt as he clawed his way back to consciousness. His chest ached. His limbs felt like stone. The taste of blood clung to his tongue.


He lay beneath the shattered remains of a wagon, the silver glow from before now faded. His wounds were gone—no, not gone, but closed. His body was still a mess, but it wasn't bleeding anymore.


He coughed, trying to sit up. The broken sword was still in his hand, its edge chipped and dull. His mind reeled.


"Was that… real?" he muttered. "The voice… that pressure..."


The voice returned—clear, cold, and impossibly close.


> "You remembered. Good. That means your brain isn't completely rotten."


The voice echoed inside his head, not spoken, but felt—each word carrying the weight of ancient battlefields and rivers of blood.


> "You gambled your life. Most would've begged or run. You charged like a mad dog."


"Stupid... but not entirely worthless."


Shun frowned. "I didn't do it to impress you."


> "Obviously. You did it because you hate being powerless."


> "That's the only reason I'm speaking to you now. I've seen your memories. Your world was peaceful—soft. But deep inside, you've always hated being weak."


Sei Muyang's tone shifted, still cold, but more focused.


> "So here's the deal, brat. You survived my soul pressure. You've got guts. But guts alone won't save you in Murimdan."


> "From now on, I will teach you. Not because I want to—but because I need your body to become strong."


> "My soul is bound to this system. I can't reincarnate. Not unless my host reaches a level of power strong enough to break fate itself."


> "We both have a goal, Shun Seijuro. Yours is survival. Mine is freedom. If you want to live, and if I want to escape this prison, then we walk the path of demons together."
