Deep in the modern city, where neon lights and shadows intertwine, there flows an invisible river—the "Abyss of Original Sin" formed by the accumulation of human sins. A few awakened ones can glimpse its existence, and they are called "gazers."
Delivery boy Chen Ye accidentally witnessed the scene of a rich man's mysterious death while delivering food on a rainy night, and awakened a strange ability: through other people's pupils, he could see fragments of sinful memories hidden in them. Along with the ability comes the police wanted, the pursuit of the mysterious organization "Scavengers", and the covetousness of the technology giant "Creation Gene".
He formed an alliance with Lin Ran, a female detective who was suspended for violating regulations. The blood-stained old case files in her hands pointed to a serial killer codenamed "Gear Master", and all clues were closely related to the non-standardized gears left at the scene.
At the same time, the "Scavenger" who has been inherited for thousands of years vows to clean up all abyss pollution, and technology companies are trying to genetically reproduce this power. The hosts of the Nine Original Sins quietly awaken and turn the city into a hunting ground...
When you stare into the abyss, the abyss stares into you.
But what if the abyss itself is a reflection of human sin?
