In the distant future, extreme climate causes most of the land to be submerged by sea water. The people who survived built Wuji City on the only tiny land. In order to survive, pirates, coast guards, and sea wanderers have to embark on a journey to find a new continent, and a new era of navigation begins. After a pirate fleet raid, the Wuji City Coast Guard accidentally obtained a treasure map of the "New World". Due to the dangers of the sea route, the deep-sea monster "Lantern Ghost King" lives in the "Dead Sea" in the deep sea of the doldrums. The coast guard "Luo Li" had to release the sea whisperer "Hai Ji" who was imprisoned in the sea prison and could listen to the voices of all things, and teamed up with her fleet to embark on a journey full of fantasy adventures to find a new continent.
