Linyuan City is a city built on the cracks of the abyss.
Sun Gaoze, the most inconspicuous sewer maintenance worker in Nancheng District, lives with dirt every day and has become a trash that everyone can bully. No one knows that his body has long been symbiotic with the abyss - he can see the "pollution value" in everyone and can strip away the fate of others who are about to be alienated.
Wang Jiaqi, the youngest S-class captain of SCA, is a woman as big as an iceberg. She investigates a case of an attack by an alien creature from the abyss, but all the clues point to this maintenance worker who has no energy fluctuations.
She thought he was hiding his strength and was up to no good. He thought she was rigid, stubborn and indiscriminate.
It wasn't until the abyss crack erupted again and ancient ruins awakened beneath the city that they discovered: The truth behind the collapse of the world was hidden in the crack thirty years ago. And the only one who can save this city is the person who is regarded as a monster by everyone.
