The Spy Life in the Demonic Sect

For fourteen years, Iseo Jang has lived a dangerous double life as the Murim Alliance’s most gifted undercover operative. Embedded deep within the Demon Sect, he earned the fearsome moniker “Rabid Dog” through his ruthless efficiency as their counterintelligence agent. Yet despite his unparalleled skill in deception and martial arts, his latest directive pushes the boundaries of reason: he must transform Wu Ma—the sect’s most infamous and lethargic delinquent—into the next Cheonma. To accomplish this seemingly impossible task, Iseo abandons his established position and volunteers to become Wu Ma’s official aide. Navigating a treacherous environment defined by constant betrayal, deadly combat, and cutthroat political maneuvering, he must find a way to mold an utterly hopeless young master into a legitimate heir. In a world where a single misstep means death, even a prodigy like Iseo faces his greatest challenge yet.
