When an order you cannot refuse drags you into the abyss under the city——
Delivery boy Chen Feng was forced to take a "deviated delivery" order in order to save his daughter who had a neurological abnormality. The destination is not an ordinary address, but an abandoned FM tower on the edge of the city. The rewards are generous, but the requirements are strange: if the street shape is abnormal when delivered, please send to an alternate address.
From then on, his world began to go out of order. There was noise at a frequency that shouldn't exist in the headphones, and unexplainable signal afterimages flashed before my eyes. He found that he had become a walking "beacon". Under the surface of the neon city, he saw another dimension: the chaotic signal area, the wandering information entities, and the horrifying secrets hidden in the "Seventh Maintenance Factory" buried deep underground.
For the sake of his daughter, he must survive in this city full of invisible traps and find a way to close the "source of pollution" - even at the cost of becoming part of the abyss.
This is the story of a father falling into the unknown for love, and also a thrilling escape about sounds, signals and urban memories.
