The Regressed Mercenary’s Machinations (Korean: 회귀한 용병의 권모술수, RR: Hoegwihan Yongbyeong-ui Gwonmosulsu) is a compelling "Regression" and "Dark Fantasy" webtoon and web novel written by Nabi and illustrated by D-No. It is highly regarded for its focus on political maneuvering, tactical brilliance, and a protagonist who uses his brain as much as his blade.

The story follows Chris, a veteran mercenary who spent his entire life fighting in a brutal war that ended in the total destruction of his world. At the moment of his death, he is sent back in time to his youth—specifically, to the point before he became a lowly mercenary. Unlike many "Returner" stories that focus purely on physical leveling, Chris realizes that power without influence is useless. He decides to use his knowledge of the future's political betrayals, hidden resources, and military strategies to become the "shadow" behind the throne, manipulating the continent’s most powerful figures to prevent the coming apocalypse.
