The Dragon Slayer's Regression on Another Level (Korean: 용살자의 회귀는 레벨이 다르다, RR: Yongsaljaui Hoegwineun Rebeori Dareuda) is a top-tier action-fantasy manhwa produced by Studio LICO (the renowned studio behind Return of the Blossoming Blade). It is widely praised for its cinematic art style and its high-speed approach to the "overpowered regressor" trope.

The story follows Sion, the last humanity-saving Dragon Slayer who lived through a total apocalypse. After killing the final Dragon King at the cost of his own life, he regresses to his days as a young cadet in a military academy. Unlike his first life, where he struggled to keep up, he now uses "Another Level" of training methods, future knowledge of hidden artifacts, and mastered breathing techniques to reach peak power before the first dragon invasion even begins.
