Takeaway rider Xu Linchuan received an order that could not be cancelled.
The delivery address is a non-existent floor in the closed old building.
The person who placed the order was another version of myself covered in blood.
The other party put half of the access ring and a gun without a crosshair into his hand, and only had time to say:
"They killed me in that world, now it's your turn."
The next second, Xu Linchuan was sent into a doomsday city where gravity kept flipping.
