Li Xiaohai, a ten-year-old "troublemaker" in Chiling Village, can climb trees to pick coconuts and burn earth temples. He dreams of becoming the "Pirate King" in the animation. Late one Saturday night, he stole a broken plastic boat and went fishing, but it drifted into the deep sea because he fell asleep. During the storm, he dealt with sharks and dolphins, and was so hungry that he fished and gnawed on sashimi; in the dark night, his lightless boat was nearly hit and sunk by cargo ships many times, and he missed rescue. After drifting all night, he gnawed on seabird meat until he was rescued. When he was pulled aboard a yacht in Sanya, he devoured it, and the video went viral on the Internet. After returning home, his parents were about to beat him up, but they were interrupted by the swarming TV reporters. Xiaohai pumped his fist and shouted: "I want to be the pirate king!" On Monday, he became the school's "little hero", but he was also criticized for bringing bad habits. His parents, who drained the ponds in the village and searched the mountains, were angry and hurt. The saying "A calm sea cannot produce good sailors" became his belief. Many years later, before he became the Pirate King, he put on a navy uniform, stood on a warship and looked out at the sea, and his childhood adventures became a beacon in life. This is a sea story about courage, growth and dreams.
