When unidentified calamities strike Earth, humanity is forced to enter a mysterious multi-tiered Labyrinth constructed by higher deities. Every entrant must choose one of four difficulty settings: Easy Mode for basic survival, Normal Mode for standard combatants, Hard Mode where only one percent endure, and Solo Mode, a lethal gauntlet where no participant has ever cleared the descent alive. In his first run, Kang Taesan chose Easy Mode. Through sheer diligence, he climbed to become the strongest survivor of Earth, only to watch humanity wiped out by ancient gods and their divine apostles. Easy Mode granted safe passage but placed a hard ceiling on power, withholding the supreme concepts required to challenge transcendent entities.

Faced with total extinction, Taesan is granted a second chance through temporal regression. Retaining his veteran combat instincts, battle memory, and unyielding tactical clarity, he rejects the security of Easy Mode and deliberately selects Solo Mode. Inside this hostile, isolated progression environment, the Labyrinth rewards extreme physical strain and lethal risk with unrestricted skill creation. Taesan systematically acquires active martial styles, black magic, elemental contracts, and conceptual proficiencies by meeting absurd combat conditions, transforming himself from a cautious survivor into an unstoppable force destined to confront the ancient gods.

What to Expect

Skill Master Levels Up focuses heavily on granular skill mechanics, meticulous trial clearance, and high-difficulty dungeon crawling. Combat is tactical and exacting: rather than relying on unearned system handouts, the protagonist earns every skill proficiency percentage by executing specific martial techniques, enduring mortal hazards, and striking contracts with enigmatic entities. Readers will experience continuous floor-by-floor progression, intense solo boss duels, expansive world-building involving higher pantheons, and steady narrative escalation free of romantic detours or prolonged filler arcs.
