On a rainy night in T City, delivery boy Zhong Ze received a strange order, and the address was the abandoned "Xingfuli Community". The navigation points to the wasteland, but seven gray-white buildings appear out of thin air. The iron doors are closed tightly, and the building numbers change strangely. Anyone who tries to leave will be trapped in a loop.
This is a death order: if it times out, it will cause heart paralysis. You need to explore the content of the order by yourself.
The twenty-two rules of Building 4 are shrouded like a curse: the non-existent 13th floor is brightly lit at midnight; the scratches in the stairwell will tempt you to count to the 13th, and pale hands will stretch out from the wall; the man in white whispers in the corridor, asking if you heard the sound; the shadow in the mirror is not you, and will show a strange smile.
Zhong Ze struggled in this man-eating building. The bloody words in his notebook guided him to find the non-existent Room 404. The man in the mask asked him to donate blood to complete the ritual. Sacrificed once every ten years, the fate of the deliveryman has already been determined.
In the countdown to death, can Zhong Ze find a way to escape? This isn't delivering food, it's a race against death, and it's a game against fear. The rainy night is endless, and the truth is buried behind the rotting walls.
