The Spy’s Life In The Demonic Cult

Iseo Jang is the Murim Alliance’s most gifted spy, having spent fourteen years infiltrating the Demon Sect. During his long mission, he earns the fearsome nickname “Rabid Dog” while serving as the sect’s ruthless counterintelligence agent, gaining the trust of even its highest-ranking members.

Just when he believes he has seen every impossible assignment, he receives his strangest mission yet: transform Wu Ma—the Demon Sect’s laziest, most infamous troublemaker—into the next Cheonma, the supreme leader of the sect.

To accomplish this seemingly impossible task, Iseo abandons his current position and becomes Wu Ma’s personal aide. Surrounded by deadly conspiracies, political intrigue, and fierce martial artists, he must somehow mold an irresponsible young master into a worthy successor. But in a world where betrayal is commonplace and every move could cost him his life, even a legendary spy like Iseo may find this mission to be his greatest challenge yet.
