The Regressed Mercenary Has a Plan is an action-fantasy manhwa by Park Jin-Seok that follows Cecil Perdium, the legendary Mercenary King, who is slain in battle before he can avenge his family's destruction — only to wake up in his teenage body with all of his memories intact and a burning resolve to rewrite his fate.

What sets this series apart is its layered blend of time travel, age regression, and revenge driven by a genuinely strategic protagonist. Rather than simply growing stronger, Cecil must repair his noble family's crumbling reputation, stop soldiers and knights from defecting, and outmaneuver the shadowy nobility and aristocracy responsible for his downfall — all while navigating royal affairs, kingdom management, and large-scale war. The full-color, webtoon format by Park Jin-Seok delivers dynamic swordplay and intense monster battles alongside sharp political intrigue, making it a standout in the seinen and shounen manhwa space.

With 88 chapters and counting, this ongoing series rewards readers who love a strong male lead with a concrete plan and the grit to see it through. Read every chapter in high quality and experience one of the most compelling regression fantasy manhwa available today.
