Read manhwa The Spy’s Life In The Demonic Cult / 첩자의 마교생활 / A Spy’s Survival in the Demonic Cult / The Spy Life in the Demonic Sect / 密探的魔教生活 / 間諜的魔教日常
Jang Yiseo, a spy from the Murim Alliance who infiltrated the Demonic Cult, was given his first and last mission. To make the notoriously unruly Seventh Young Master, Ma-oh, the Vice Cult Leader! Despite his extraordinary martial prowess, Yiseo’s potential was hindered by his frail constitution. Meanwhile, Ma-Oh, a prodigious yet unpredictable force, walked the fine line between genius and madness. As their fates intertwined, the two had to navigate treachery, power struggles, and the ever-present risk of exposure. Can Jang Yiseo make Ma-Oh rise to the rank of being second only to the Cult Leader, or will the shadows consume them first?

Intriguing… it’s kinda actually well built. Most of the characters are smart, it’s just that our MC is simply superior in intellect. Kinda fun to read it as mostly it’s mind games related stuff.
