Imagine being thrust into a vibrant fantasy world, ready for adventure... only to be trapped in the *tutorial stage* for two agonizing decades! That's the absurd reality for Hanbin Ryu. Fresh out of military service and searching for purpose, he finds himself ripped into a realm teeming with magic and monsters. But his supposed survival system, the "guide line," bugs out spectacularly, turning his beginner's quest into an inescapable, endless grind.

After twenty years of involuntary, grueling training – and an unprecedented level of sheer frustration – Hanbin finally breaks free. But the world waiting for him is anything but welcoming. Otherworlders like him are now feared, hated, and hunted. He might technically be a "low-level" newbie, but he carries the hidden scars and unparalleled combat prowess forged in two decades of relentless, forced growth.

How will this walking paradox – a super-tutorial veteran with an underdog status – navigate a hostile fantasy realm that wants him gone? Brace yourself for an electrifying action adventure as Hanbin, the reluctant Sword King, redefines what it means to survive!
