Lin Letian and other five people got the opportunity to explore the mysterious "Gate to the Star Sea" due to an adventure. In order to realize their dreams, they formed an adventure team and entered the star sea world full of unknowns and weirdness. From desert ruins to ice jungles to high-tech fantasy cities, break through levels and solve puzzles along the way. The team members continued to collide due to their personality differences, and they gained growth in resolving crises and helping each other. Across three major areas, each faces their own inner challenges, and finally joins forces to uncover the ultimate secret of the star sea world. They used humor and wisdom, moved and laughed to write a youth adventure story of their own.
