Six teenagers accidentally got a mysterious map made by their left hands during the vacation, and decided to form a team to track down the ancient secret treasure hidden in it. The story sets sail from a desert island and involves mysterious ruins, monster chases, maze escapes and global cross-region adventures. They must work together to solve puzzles, fight traps and deal with difficulties. Humor and crisis coexist, friendship continues to deepen, and everyone finds their own answer to life as they grow. The three volumes are self-contained and interlocking, and finally complete their mission.
