The Soul Nurturing Technique of Tianshui was one of the arts within the Tianshui Divine Art, the inherited tradition of the Tianshui Sect.
Previously, when Lin Bai had encountered Yi Gu on the Water Mirror Sea, the two had confided in each other, and Lin Bai had learned that Yi Gu had come to the Tianshui Sect precisely for this art.

Lin Bai smiled. "There's no need for that. If I ever come to the Seven Nights Divine Sect's territory, just prepare two jars of good wine for me."
Yi Gu laughed heartily. "That goes without saying!"
Lin Bai said, "Don't rush to leave either. Cultivate the Soul Nurturing Technique of Tianshui properly within the Tianshui Sect. If there's anything you don't understand, feel free to
