In the future, human beings huddle in the high-tech barrier "Sky City" to resist the terror on the other side of the "Curtain of Silence" in the dimensional rift.
Lin Zhou, a "data cleaner" living at the bottom of society, lives an ant-like life. However, a sudden "curtain falling" incident not only involved him in a near-death situation, but also allowed him to awaken the most powerful power that can subvert the world - [Reverse Cause and Effect].
Missed bullets can hit, collapsed buildings can be restored, and the established "results" can all be reversed in his eyes.
In order to track down the truth behind the mysterious disappearance of his parents many years ago, he put on an ordinary mask and sneaked between the neon lights and shadows of the city. Giant corporations, iron-fisted adjudicators, mysterious sects... All forces are intertwined, and every step is like walking on thin ice.
When the spearhead of the truth points directly at the monstrous conspiracy shrouding the entire city, and when the gears of fate have already begun to turn, can he, the only "variable", reverse the already destined outcome?
This is a story about choice and price, struggle and protection.
"If fate is a chain that cannot be broken away, then I will reverse it with my own hands."
