Lee Cheol is born into the prestigious Esteemed Martial Lee Clan, but his status as an illegitimate child condemns him to ridicule and exile. Forced to live in the shadows, he is eventually hunted down and killed as part of his family’s internal schemes. Death, however, grants him a second chance. Regressed to the past, Lee Cheol awakens with a unique ability that allows him to absorb the memories and techniques contained within weapons. Using this power as his foundation, he begins a relentless journey of training and survival. Caught between inheritance conflicts, interspecies threats, and dangerous unexplored lands, Lee Cheol must grow stronger to protect himself and those around him while uncovering the hidden truths of his previous life.
The Illegitimate Who Devours Weapons combines familiar regression elements with a distinctive growth mechanic centered on weapon memory absorption. Rather than relying solely on innate talent, Lee Cheol’s progression is shaped by the weapons he encounters, giving each battle and acquisition lasting significance.
The story balances personal conflict with broader threats, weaving family politics, inheritance struggles, and external dangers into a steady climb toward power. Lee Cheol’s motivation evolves beyond revenge, shifting toward survival and protection, which adds depth to his journey.
While the narrative follows recognizable genre structures, its execution remains engaging due to its ability-driven progression and persistent tension. Readers who enjoy regression stories with unique power systems, illegitimate heir conflicts, and continuous struggle will find this manhwa a compelling read.
