### Summary
The murder mystery arc intensifies as Jin Mu-Won travels toward the Heavenly Alliance headquarters. What began as a suspicious death aboard his vessel is revealed to be part of a larger, more sinister conspiracy involving a cult that exploits young children. The primary culprit behind these heinous acts is not a previously established foe, but the son of an antagonist known as the "mighty fist," suggesting a new generation is continuing a legacy of evil. This development highlights the pervasive corruption of the martial world, directly implicating the Heavenly Alliance, whose reckless distribution of forbidden techniques has armed its own future enemies. The unfolding events suggest that the Alliance's past sins are now culminating in self-destruction, potentially heralding the arrival of a new major antagonist for Mu-Won to confront.
