A set of mysterious coordinates in the museum became Lin Xia's only clue to find the missing person Lu Chuan. Following the clues, she discovered that the coordinates coincided with the "Xingshu Secret Realm" recorded in the fragmentary scrolls of the Song Dynasty, and the entrance to the secret realm was hidden in the burial pit of Qixingdun Han Tomb.
The visit of archaeological researcher Zhou Mingyuan confirmed the clues - the burial pit symbols are consistent with the bronze mirror star cloud pattern, and the coordinates were also left by Lu Chuan. Lin Xia and her friend Su Qing joined the exploration team and embarked on the adventure together with Zhao Qiang, Li Mo and Chen Yu.
They cracked the Big Dipper mechanism and entered the burial pit, found the parchment scroll and the bronze token, and learned that they needed to pass three levels: "Star Shadow Array", "Water Curtain Maze" and "Flaming Furnace". On the way through the barrier, the appearance of the Xingshu Bead gradually revealed Lu Chuan's traces, but it also attracted the covetousness of the evil clone in parallel time and space.
From repelling clones to repairing the time and space bug in the "Misty Forest", to resolving the black hole crisis in "Time and Space-073", the crisis has been lifted time and time again, but the bronze mirror suddenly points to an unknown and dangerous time and space. This adventure across time and space is far from over.
