Life of a Spy in the Demonic Cult

Jang Yi-seo, a spy more demonic than the Demonic Cult itself.

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 Yi-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 Yi-seo, the genius spy who fell into the Demon Sect, and Mao, the eccentric young man.
