From Zero to Overpowered
In the world of Aethelgard, fate is not written in the stars—it is decided by the cards you hold. While the nobles of the Spire are born with legendary Golden Decks filled with dragons, holy magic, and divine relics, the poor are left with broken scraps barely worth surviving with.
Kai is nothing more than a nameless mine slave with no Deck, no status, and no future. But when a deadly cave-in uncovers a hidden flaw in the world’s perfect system, his destiny changes forever.
Buried beneath the ruins, Kai discovers [The Wildcard]—a corrupted card capable of becoming anything.
A god-slaying sword.
A forbidden spell.
A monstrous beast.
Or… a useless wooden spoon.
Unstable, unpredictable, and feared by the system itself, the Wildcard turns Kai into a threat to the very order of Aethelgard. Armed with a chaotic deck forged from literal trash, stolen relics, and impossible combinations, Kai enters the brutal climb of the Spire where every duel is a gamble and every defeat means death.
To survive, he must outplay nobles, crush legendary card wielders, and uncover the truth behind the Deck system that controls the world.
Because in Aethelgard, power belongs to those lucky enough to draw it.
But Kai was never lucky.
He cheats fate itself.
A dark fantasy progression novel packed with ruthless battles, evolving cards, deadly tower climbs, and a zero-to-overpowered journey where the weakest slave may become the greatest wildcard the world has ever seen.

Chapter: THE JOKER CARDThe purple light didn't just shine; it infected the very reality of the alleyway.Raindrops froze in mid-air, turning into suspended amethyst crystals. The mud on the ground began to boil.Lieutenant Kaelen released Kai’s throat and stumbled back, his instincts screaming that he had made a fatal mistake. He raised his Greatsword, but his hands were trembling.Kai fell to his knees, clutching his chest. He watched as the interface in his vision cracked and rebuilt itself.--------------------------------------------------[System Alert: Mana Overload Detected!][Wildcard Limits Breached.][Rarity Upgrade: Temporary Legendary.]--------------------------------------------------The color wheel spinning in Kai’s vision moved so fast it became a white blur. Then, with the sound of a visual snap—like lightning striking a mirror—the spin stopped.It didn't land on Gold. It didn't land on Red.It landed on BLACK.The color of the Void. The color of Death.------------------------------------

Chapter: 19 THE AMBUSHThe sun had set hours ago. A relentless, cold rain lashed against the corrugated tin roofs of Sector 7, turning the dirt streets into rivers of mud.Kai walked alone, his hood soaked through. He wasn't heading home. He was moving toward the edge of the district, intending to slip past the blockade and vanish into the wilds for a few days until the situation cooled down.He turned into "Dead Man’s Alley"—a narrow shortcut between two abandoned factories.Suddenly, the sound of the rain stopped.The thunder, the splashing of his boots, the distant hum of the city—all of it vanished instantly. The world didn't just go quiet; it went mute.Kai stopped. He stomped his foot. No sound. He tried to speak. No sound came out.--------------------------------------------------[System Alert: Zone Effect Detected][Card: Sphere of Silence][Effect: Negates all sound waves within a 50-meter radius.]--------------------------------------------------A trap, Kai realized, his heart hammering agains

Chapter: 18 EVOLUTIONThe Iron Guild's Coin Exchange was a brilliantly lit building on the main thoroughfare. Rows of terrified merchants and F-Rank adventurers stood outside, clutching their gold pouches tight to pay their "Protection Tax."Kai stood across the street, watching them from the shadows.In his hand, he held the heavy sack of 5,000 coins. It was his ticket to freedom. He could have just crossed the road, handed it over to Lieutenant Kaelen, and bought himself another month of peace.Kai looked at the bruise on his arm from the arena wolf’s bite. He looked at the cracked edge of his [Bone Shiv]."Peace is just a slow death," Kai whispered.He turned his back on the Guild building. He walked into the darkness of the Lower District, heading toward a shop with no name—only the crude symbol of a black cauldron painted on the door.He knocked. Three times slow, two times fast.A viewing slit slid open. A pair of goggles peered out."We’re closed," a gravelly voice came from inside."I have gold," K

Chapter: 17 THE UNDERGROUND PIT (THE PIT)The entrance to The Pit wasn't marked on any map. It was hidden beneath a butcher shop in the slums, accessible only to those who knew the password ("Fresh Meat").Kai descended a spiral stone staircase. The air grew hotter with every step, vibrating with the roar of a distant crowd.At the bottom, a massive basement had been converted into a blood-sport arena. A rusted iron cage stood in the center, surrounded by wooden bleachers packed with gamblers, thieves, and off-duty guards.Kai approached the Bookie, a goblin with gold rings on every finger."I want to fight," Kai said.The goblin eyed Kai’s lean frame. "The suicide booths are at the end of the hall. This is for fighters.""I need 2,000 coins," Kai slammed his hand on the counter. "Put me in a high-stakes match."The goblin raised an eyebrow. He smirked, showing sharp yellow teeth. "2,000? That’s the main event pot. But you’re a nobody. No one will bet on you.""Then give me the opponent that no one else wants to fight."The g

Chapter: 16 THE IRON GUILDThe tavern went deathly quiet.It wasn't the sudden silence of a fight about to break out; it was the suffocating stillness of absolute fear.The man in polished steel armor stood up from his corner booth. He didn't just walk; he marched. His iron boots clanked rhythmically against the wooden floorboards, each step echoing with absolute authority.Kai didn't look up from his stew, but his hand moved slowly beneath the table, gripping his deck.The soldier stopped at Kai’s table. He placed a gauntleted hand on the wood."You’re sitting in my seat," the man said, his voice smooth yet razor-sharp.Kai looked around. The tavern was half-empty. "There are plenty of open tables.""But I like this one. It has a good view of the door."The soldier smiled, but it didn't reach his eyes. He pulled out a chair and sat across from Kai, uninvited.From this close, Kai could see the intricate details of the armor. The breastplate bore the emblem of the Hammer and Anvil—the mark of the Iron Guild.Ka

Chapter: 15 HUMAN NATUREThe alley was narrow, choked at both ends by the rotting timber of the slum buildings. The only light came from a flickering streetlamp, buzzing with dying mana.Kai set the burlap sack down gently. Clink."Three against one," Kai noted, his voice steady. "The gold standard of cowardice, isn't it?"The leader of the trio, a man with a thick neck and a wooden mace studded with rusted nails, stepped forward."We prefer the term 'business partners,'" the thug sneered, revealing missing teeth. "You’re new. You don't know the rules of Sector 7. You walk our streets, you pay the toll."He pointed his mace at the sack. "Leave the loot. Walk away. And maybe you get to keep your teeth."Kai scanned them using his basic interface.* Thug A (Leader): Level 4 [Brawler]. Weapon: Spiked Mace.* Thug B: Level 3 [Thief]. Weapon: Knife.* Thug C: Level 3 [Mage - Unawakened]. Weapon: Spark Spell.They were weak. But unlike monsters, they were intelligent. They circled him in a triangular formation.I c
