Plot Synopsis: Unveiling the Mystery of the Water Ghosts

Where the Yellow, Yangtze, and Lancang Rivers converge lies a hidden world inhabited by three legendary "Water Ghost" clans: the Ding, Jiang, and Yi. These aren't ordinary spirits—they're master geomancers and treasure hunters with the ability to move through water as freely as humans walk on land. Yi Sa, the sole survivor of her lineage, runs a secret "underwater bank" along the Lancang River, preserving her clan's legacy in the shadows. Her life takes a dramatic turn during a dangerous "Golden Soup" expedition when she rescues Zong Hang from certain death.
