In the ruined city lit by the embers of stars, young Yun Zhao makes a living by weaving stardust. There is a "reverse spectrum" forgotten by the universe hidden in his soul, which is the music of all failed fates. The fate reaper of the Galactic Empire has arrived, announcing that the fate of all things has been decided, but Yun Zhao accidentally picked up a wandering note that refused to cycle - as long as it is played, the destined ending can be reversed. His motivation is not only to save himself, but also to find his own melody for all the lives that have been wiped out by fate.
In the interstellar wasteland and the time and space corridor, Yun Zhao formed a "retrograde band" with a group of companions who were abandoned by fate. They used their lives as notes to compose a cosmic fantasy that swept across the galaxy. Their opponent is not flesh and blood, but the ancient laws and destiny itself. Every time the music plays, the universe trembles - should we obey the ultimate order, or should we use our own will to rewrite destiny?
This is a collision about freedom and destiny, dust and the sea of stars. Yun Zhao used reverse spectrum to tear apart the web of fate, igniting the hope of hundreds of millions of stars, and allowing countless forgotten voices to converge into the most magnificent harmony in the universe.
