In the future city "New Green Star" suspended above the sea of clouds, civilization is strictly divided into two classes: the "sky dwellers" who live in the glamorous upper city, and the "earth dwellers" who struggle in the industrial ruins of the lower city.
Ling Chen, an unknown "earth nester", whose only identity is that of a father. His daughter Ling Xi suffers from an incurable genetic decay disease - the "hourglass of time", and life passes quickly like an hourglass. In order to pay for his daughter's expensive life support, Ling Chen made a living by scavenging, searching for the remaining value in the huge metal cemetery every day.
An unexpected collapse of the ruins allowed him to discover an object that did not belong to this era - a flawless black cube with an unknown star map engraved on it. When his blood touches the cube, a cosmic relic that has been sleeping for eons is awakened.
There are no tasks, no property panels, and no cold system prompts. What this "relic" brought to Ling Chen was the lowest level of perception and resonance of matter, energy, and even time. He can hear the "fatigue" of metal, see the "flow" of energy, and feel the "folds" of time.
In order to save his daughter, Ling Chen must learn to use this power beyond imagination. But this "stardust relic" is not only the only hope to cure her daughter, but also a taboo object coveted by countless powerful forces. Giant technology companies, mysterious government agencies, and other "relic" holders lurking in the shadows have all drawn him into a whirlpool far beyond imagination.
