Secrets of the Rivers

Yi Sa, the last Water Evil of the Yi family, runs a unique underwater business along the Lancang River. His life changes when he saves Zong Hang during a Golden Fortress excavation, which sets off a chain of events leading Yi Sa to train Zong Hang as a Water Evil. Water Evils from the Ding and Yi families, including Ding Yudie, possess skills in geomancy, feng shui, and treasure hunting, allowing them to move freely in the water.
