Su Luoyuan gave birth to a child who was different from ordinary people, Zhao Zhao. She thought that mother and child would inevitably die, but they were secretly protected by Emperor Yin Lin in a seaside courtyard. Concubine Hua tried to assassinate him out of jealousy, but she was shocked to find out that Yin Lin was the king of the sharks who had endured for many years. He had suffered a lot in order to walk on land using the forbidden technique of turning his tail into legs. In order to save Yin Lin, who was poisoned, she bravely broke into the prison to get the antidote. In the end, Yin Lin revealed the true identity of the shark in public, calmed the world's criticism, held a grand wedding for her in the holy land of sharks, and finally stayed together happily.
