Description

He receives his first and final mission.
[Make the Seventh Young Master the Vice Cult Leader.]Pushing aside all the brilliant heirs, he must place the good-for-nothing Seventh Young Master – who lacks martial arts, connections, wealth, and dignity – at the top.
A truly impossible mission!
But what choice does he have? When ordered, one must obey.
“Vice Cult Leader. I will make it happen.”
Though born with nine holes in his dantian, a cursed fate,
Jang I-seo, is a half-genius with extraordinary intelligence and intuition.
His impossible mission begins.
“I’ll make it work somehow.”
Even if it means becoming the Cult Leader himself.
…
“But isn’t that missing the point?!”
A spectacular tale of conquering the Demon Sect, featuring Jang I-seo,, the genius spy who fell into the Demon Sect, and Mao, the eccentric young man.

I have very complicated feelings to the main character. I really love author previous work 'Reincarnated as an unruly heir' (also got webtoon adaptation). In that one, my fav chara is one murim spy in demonic cult who get entangled with cult heir, same like Jang yiseo, but with far more tragic fate. Seeing a character with same setting as my beloved tragic kid get to be a main character and enjoying success make me feel bitter and sad. Especially since author nim forgot all about my baby in unruly heir, this novel really feels like him saying "oh my bad about that one, here's him if he's succesfull "
