At two o'clock in the morning, Lin Zhao, the night shift worker at the funeral home, received a strange phone call. From that moment on, his life was dragged into the deepest darkness of the city.
In this city, certain forgotten corners will become "forbidden zones" at specific moments. Old corridors, abandoned factories, unmanned private rooms, late-night subways... Once you step into them, you must abide by the rules.
Some unexplainable rules. Those who break the rules will be swallowed up by darkness as if they never existed.
Lin Zhao was originally just an ordinary person struggling to survive on the verge of life and death, but unexpectedly awakened the power of "lighting the lamp". As long as he lights up the abnormal objects, he can see the incomplete rules in the restricted area and the obsession of monsters.
Thoughts, and the only way to survive the situation. But every time he lights a lamp, he loses an important memory of his own.
And as the notebook left by his father, the mysterious metal box, and the truth about the "black light incident" that disappeared for many years gradually emerged, Lin Zhao discovered that he was not involved in all this by accident.
Someone is secretly following him.
Someone was waiting for him to open that door.
Others believe his father is the only one who knows how to end the disaster.
When the city lights gradually fail and the restricted area begins to spread into reality, Lin Zhao must find the truth before forgetting himself.
