In the unforgiving world of Eria, Lee Sung-min spent thirteen years as a bottom-tier, “No-Class” mercenary, only to meet a pathetic and lonely end. However, a miraculous encounter with a Regression Stone grants him a second chance, sending his soul back to his thirteen-year-old self. Though he returns with the same mediocre talent and baseline stats, he now possesses the ultimate weapon: over a decade of future knowledge and bitter experience.
Driven by the trauma of his past life, Sung-min avoids his previous mistakes by making calculated, high-stakes moves. He undergoes a grueling bone-reconstruction procedure to acquire a “Martial Bone” and secures legendary techniques like the Amethyst Cloud Art. His journey is a methodical ascent from a discarded weakling to a formidable powerhouse. By embracing suffocating discipline and relentless training on Mount Mush, Sung-min begins to rewrite his destiny, evolving into an entity capable of challenging the very masters who once looked down on him.
