Folklore anchor Zhang Xiansheng specializes in telling urban ghost stories, but due to a strange commission with a reward of one million yuan, he stepped into the real taboo place - Jingshan Apartment. In the unfinished building, teammates disappeared one after another in incomprehensible ways in front of the live broadcast camera: a scream, a broken shadow, which was the complete erasure of existence.
After surviving the disaster, he, who was deaf in his left ear, was recruited by the official organization AIB, only to find that the world was already full of holes. The ancient consciousness "Echo of the Abyss" awakens underground, turning mankind's collective fear into cold "killing rules." The ghost security guard follows the voice to claim his life, the reflection in the mirror usurps reality, and lies can be verified as truth by the rules... Violence is meaningless here. Only extreme logic and calmness can penetrate the rules and fight for a glimmer of life in a dead situation.
Zhang Xiansheng led the "Young Goose Team" and went deep into dangerous places where the rules were distorted one after another. They are not only investigators, but also night watchmen walking on the edge of the abyss. They use the warmth of humanity as a lamp and the edge of reason as a blade. In the silence of despair, they guard the last territory of human civilization.
The rules are in effect and logic is the only weapon.
