Before his death, Ryuzen Kurogane was known as the Ultimate Martial Emperor a man who mastered every combat art: swordsmanship, magic, stealth, archery, ki manipulation, and divine martial styles long lost to history. Yet in the end, he was betrayed by his disciples and fell in battle against gods.
But death was not the end.
Reborn as a slime in the deepest layer of an ancient dungeon, Ryuzen awakened with every skill still echoing within his soul only dormant. Surrounded by monsters, dragons, and divine beasts, he devoured them one by one, gaining their abilities and evolving beyond anything the world had seen.
Now known as Ryuslath, he becomes one of the Four True Dragons beings said to embody the laws of creation itself.
But the other three dragons Veldra (Storm Dragon), Ignira (Flame Dragon), and Frostalis (Ice Dragon) are not mere allies.
They are his siblings, bound by fate and rivalry, destined to reshape the world itself.
Chapter 1: The Slime Who Devoured Death
The dungeon's air was thick with the stench of rot and magic.
Crimson crystals glowed dimly along the walls, illuminating pools of acidic liquid where monsters fought to survive.
In the center of it all… a small, translucent slime pulsed with faint golden light.
> "...So this is death, huh?"
The slime's voice echoed in his mind calm, human, yet detached.
"No body, no heartbeat… but my consciousness remains."
Memories flooded in.
Sword techniques. Elemental manipulation. Heavenly martial arts.
A lifetime of mastery sealed within a body of gelatin.
> "How ironic. I, Ryuzen the God-Slayer, reborn as a blob."
A hulking Rock Ogre approached, slamming its fists on the ground.
The slime tilted, amused.
In an instant, his body shot forward like a bullet piercing through the ogre's chest.
Then came the sound of absorption.
> [Skill Gained: Ogre Strength]
[Skill Gained: Earth Resistance]
[Evolution Progress: 1%]
> "Oh… I can absorb their essence. Interesting."
Days turned into weeks.
Each monster slain fed his growth. Each battle evolved his mind.
He learned to split, reform, cast magic through mimicry, and manipulate his form into blades and wings.
Then came the encounter that changed everything.
A roar shook the dungeon's foundations.
A voice ancient, powerful, resonating through mana itself.
> "Who dares feast within my lair?"
From the darkness emerged a colossal dragon with scales like molten gold Ignira, the Flame Dragon.
Ryuzen no, Ryuslath faced her without fear.
> "I'm not your prey. I'm your equal… though you don't know it yet."
The dragon laughed, molten fire dripping from her jaws.
> "Equal? You're just a slime."
But when his body began to glow, power surging with divine aura, her amusement turned to awe.
> "You… bear the same soul signature as us. The mark of the True Dragons."
Ryuslath's form expanded, runes of creation circling his body.
> "Then it's true. I've inherited divinity itself."
"From this moment forward I am Ryuslath, the Fourth True Dragon!"
