It tells the story of Lin Ye, a young man whose life experience is a mystery. When he was forced to have no choice but to pay rent, he picked up a rust-colored copper bell that could ring on its own in a garbage dump. This bell broke the peace he had built with "illusion" - when the blood moon hung in the sky, he saw a shadow that was exactly like his own; deep in the old alley, an old man who picked up garbage used a yellow paper man to draw a mysterious tattoo on his collarbone; old photos suddenly popped up on his mobile phone, tightly linking his life to the "Kunlong Lane Fire" forty years ago.
"Find the third gatekeeper, or you'll be trapped in the loop forever."
When the tinkling of the copper bells became a reminder, Lin Ye had to face the secret of being abandoned by his parents: he was not a delusional patient, but a chosen "vessel"; those distorted illusions were fragments of different time and space overlapping in his eyes; even his seemingly honest and honest friends had the murderous intention of wielding a knife hidden in their shadows.
Every time the bell rings, it is a tear in time and space; every time you meet "self", it is a reset of destiny. He must run in countless circular alleys, looking for the truth between reality and illusion - is he trapped in someone else's conspiracy, or is the whole world just a fantasy reflected in his bones and blood?
