A Spy’s Survival in the Demonic Cult

A spy from the Murim Alliance who infiltrated the Demonic Cult, Jang Yiseo.
He was given his first and last mission.

That mission was… to make the infamous scoundrel, the Seventh Young Master, Ma Oh, the next cult successor!

The story begins with the meeting of Jang Yiseo, a man with genius-level martial talent but limited by his physical constitution, and Ma Oh, an exceptionally gifted yet somewhat eccentric individual…!

Will Jang Yiseo and Ma Oh be able to rise to the position of one just below the cult leader, yet above all others in the Demonic Cult’s world domination?
