Regressor Instruction Manual

Synopsis

Lee Kiyoung, an ordinary man with no remarkable talents, is abruptly summoned to a perilous new world teeming with monsters and chaos. Deemed nearly worthless by the system, his only advantage is a unique ability called "Mind's Eye," which allows him to assess others' potential. Recognizing his limitations, Kiyoung cunningly aligns himself with Kim Hyunsung, a powerful regressor who has returned to this world with knowledge of future events. Through manipulation and strategic alliances, Kiyoung navigates the treacherous landscape, using his wit to survive and thrive. His journey is a complex interplay of deceit, ambition, and survival, as he leverages every opportunity to ascend in a world where strength often dictates fate.
