The Outcast: Teaching the Eldritch Arts to Everyone Has Old Celestial Master in a Panic

[The Outcast Fanfiction] [Cthulhu Cultivation] [Mastermind] [Sudden Change in Tone] [Dimensional Supremacy]

Su Yun unexpectedly falls into the world of Outsiders. The moment he opens his eyes, he's on an operating table in a secret bunker run by Anywhere Door, branded an extremely dangerous unknown aberration. At the brink of life and death, he awakens the "Eldritch Cultivation Preaching System." As long as he teaches eldritch cultivation methods, he can gain a hundredfold increase in pure cultivation and avoid the cost to his sanity!

Seeing Chen Duo suffering from a Gu poison, Su Yun smiles and teaches her the Blood and Flesh Ascension Immortal Gu Scripture. A few days later, Chen Duo is not only cured, but the Gu poison in her body has mutated into an indescribable thing covered in tentacles and eyeballs, leaving the board members terrified! To stay alive, Su Yun is forced to become a temporary worker and embark on a frenzied campaign of preaching. He teaches Feng Baobao the Soul Engraving Method, giving Bao'er-jie's shovel the power to inflict mental contamination. He teaches Wang Ye the Blind Idiot Qimen, so that every time the Taoist priest sets up a formation, he hears the whispers of the universe.

When Quanxing launches a massive invasion and finds temporary workers twisted and mutated all over the place, its evil practitioners completely lose it: "So which one of us is the cult, anyway?!"
