Shi Feiyang spoke to the Old Demon of Iron City Mountain, "If you have any methods, speak them now. If I find them truly efficacious, I will spare your daughter."
The Old Demon laughed, "For over a thousand years, you are the first to set terms with me. Well, I see you are not one to renege on your word, so I shall tell you!"
At their level of cultivation, indeed they couldn't behave like common thugs. He spoke first, and if Shi Feiyang found the proposal lacking, he could disregard it. However, if he used it, he had to release the Red Flower Princess.
The Old Demon began to explain a task that all direct descendants in their line were bound to undertake—creating Hell!
He mentioned Iron City Mountain, specifically modeled after the "Great Iron Wall Mountain" described in the "Sutra of the Original Vows of Ksitigarbha Bodhisattva" from Buddhism.
