On a stormy night, fisherman Shen Yanzhou rescues a three-year-old girl named Lili from a giant wave, finding her inside a seashell. Lili can hear the ocean speaking. She can locate schools of fish, discover cold underwater springs, and warn of hidden reefs. He Qianshan, the local tyrant, forcibly takes their catches, cuts off their ice supply, dumps wastewater, and tries to seize their fishing grounds, pushing the Shen family to the brink. But Shen Yanzhou turns a cold spring into a live-water ice storage facility, redirects the wastewater into Qianshan's own cold storage, and obtains a protected fishing license after discovering golden lobsters from the deep sea. Shen Yanzhou hosts a grand banquet with a hundred tables and officially adopts Lili. Kindness begins with compassion, and blessings spread across the entire sea.
