It tells the story of a star-crossing guardian legend that spans three hundred years. The star gate of the ancient star platform is opened, and the young boy Xiaoyu inherits his grandmother's silver pocket watch - this token contains the mark of the first guardian star messenger "Chen", which closely connects him to the seven guardian anchors of the earth (lighthouse, ancient kiln, ice lake, etc.).
In order to cope with the sudden interstellar turbulence, Xiaoyu and his partners Duoduo, Lele, and Yaya joined hands with the old guardians to gradually unlock secret clues such as the star track letters of the observers of the Republic of China and the bronze logs of the first-generation envoys. With the assistance of Lin Ze, the liaison officer of the Guardian Star, and young A Xing, they completed the energy synchronization of the seven anchors and the three pillars of the Guardian Star, and established a cross-star energy chain.
From the copper anchors of the old wharf resisting stardust erosion, to the ancient kiln fire veins replenishing energy, the ice lake water veins synergizing, to the resonance of the "Earth Plan" at the alliance meeting, the story is centered on "inheritance" and "collaboration": the experience of the old guardians, the innovation of the new generation, the collaboration of the twelve alliance planets, and finally condensed into the ultimate power of the "Double Star Energy Hub" in the Dark Stardust Defense War.
The temperature of the pocket watch, the gleam of the boundary-keeping flower, and the handwriting of the star-track diary jointly outline the belief of "defending the boundary without boundaries" - this guardianship agreement that began in the Republic of China has finally written a warm chapter in the interstellar space that spans the planet and is passed down from generation to generation.
