"The crystal bottle that Shi Feiyang gave to Jiang Shu contained the sealed Tie San Daoist.
That year, when Tie San Daoist was undergoing his tribulations, the Heavenly Tribulation, Demon Tribulation, and Human Tribulation all arrived simultaneously. In the end, his Primordial Spirit was captured by the powerful Dharma King Hagenib and taken to the Western, transformed into a Divine Demon.
Some time ago, when Shi Feiyang was retrieving treasures from the Yuan River, Hagenib released a Demon. Among the four Formless Divine Demons captured by Xiong Man's mother, one was Tie San Daoist, who was recognized and collected by Shi Feiyang.
Shi Feiyang bore no personal grudge against Tie San Daoist. It was entirely Geng Kun who had enmity with him. Shi Feiyang had taken his Iron Umbrella and now upon meeting again, sought to help him achieve liberation.
