The protagonist of the story, Xie Yixuan, is a girl who loves adventure. She learned from history books that there are many sunken ships in the lakes and oceans of humanity, some of which are warships, and some are merchant ships. The most mysterious are the pirate ships. Countless treasures have disappeared forever with the sinking of the pirate ships. Her grandfather, who has been dealing with the ocean all his life, told her: the sunken ships in the water are both underwater treasure houses and underwater tombs, and they can kill people invisibly at any moment... To satisfy her curiosity, Xie Yixuan paddled her grandfather's little wooden boat parked by the sea, drifting towards the legendary ship graveyard. Suddenly, the sky over the ocean was covered with dark clouds, flickering with pale blue lightning, as if a monster was about to swallow her, and she began to have nightmares continuously. Xie Yixuan carried a wooden niche with her, which contained a puppet only the size of an adult's index finger. This puppet seemed to have some kind of magic power, and there was a tear engraved on its cheek... Accompanyed by the little puppet, Xie Yixuan and her small boat were continuously dragged by the towering waves, rushing deeper into the sea.
