Caelum Ardentis was just a reader. A mortal boy from another world who died with a book in his hand—Extra’s Death: I Am the Son of Hades.

But death wasn’t his end. He awakens in a mythic world where descendants of gods rule through power, wealth, and divine authority. Unlike them, he begins as nothing—weak, nameless, Rust-tier.

Until lightning strikes.

Chosen as the First and Only Descendant of Zeus, Caelum inherits the Zeus System, a path to climb the Divine Tiers from Rust all the way to Omega, the throne of true godhood. With trials that test his body, soul, and will, he awakens powers unseen since Olympus fell.

By his side stands his older brother Richa, heir to their house, who loves and protects him unconditionally. But beyond their bond lies a brutal world: rival descendants, warring divine factions, and shadows of the gods themselves.

As Caelum’s spark grows into storms, he forges his own legend—wielding lightning, commanding the skies, and one day forging a divine sword capable of turning into thunder itself.

He is no extra. No forgotten pawn.

He is Caelum Ardentis, Heir of the Thunder King—the one destined to shake heaven, earth, and the remnants of Olympus.

The moment my name locked into place, the system's hum grew louder in my mind. Lightning crackled faintly at the edge of my vision, as if the world itself was waiting for me to notice it.


[Zeus System – Path of Divinity]The vessel of Zeus does not walk the same path as mortals.To rise, you must ascend through the Divine Tiers.


The screen divided into layers, each etched with runes of thunder and storm.


Rust: A shell with no spark of godhood.


Bronze: The first flicker of divine lightning.


Silver: Body begins to harden; aura of storms.


Gold: Thunder flows in your veins. Miracles manifest.


Platinum: The storm obeys your command; a fragment of a domain is yours.


Diamond: Power feared among mortals; lightning roars at your call.


Mythril: Lightning bends to your form; storms answer without words.


Adamantite: The world itself whispers your name. Your domain grows.


Obsidian: Reality fractures under your existence; mortals see a god.


Celestial: The stars themselves bow; your thunder shakes heaven.


Eternal: Death flees from you; your essence is divine infinity.


Omega: The embodiment of godhood. The throne of Olympus reborn.


My breath caught in my throat. The highest stage wasn't just power. It was godhood itself.


"Rust…" I muttered, bitter laughter rising in my throat. I was weaker than even a bronze-tier. Pathetic.


[First Trial Unlocked: Lightning's Spark]Objective: Ignite your divine spark.Reward: Bronze Rank, Skill Unseal – [Bolt Manifestation].


The window burned into my vision until it vanished, leaving only the faint thrum of thunder inside my chest.


Richa, sitting beside me, glanced at me strangely. "Caelum? You've been staring at nothing for a while. Are you sure you're fine?"


I forced a smile, though my heart pounded with fire.


I wasn't here to survive.I wasn't here to follow in anyone's shadow.I was here to climb the divine ladder—Rust to Omega.


And when I reached the top, this world would no longer speak of the gods of the past.


Caelum Ardentis—the Heir of the Thunder King.
