Gu Chang'an, a handyman on the third level of Qingyun Sect's Qi Refining, accidentally slipped while picking up a leak in the Eternal Secret Realm. He fell into the "Ruins of an Moment" together with Luo Ningshuang, the saint of the Yaoguang Holy Land, triggering the ancient prohibition and was sentenced to "the penalty of a hundred years of immobility." The two agreed not to interfere with each other. Gu Changan relied on the Bigu Pill secretly given by Luo Ningshuang to survive. Later, he discovered the underground cave, a treasure trove of resources. The two reached a resource distribution agreement and started a century-old road to coexistence.
