Li Yang, an extremely ordinary courier, shuttles through the streets and alleys of the city every day, in the wind and rain, and barely maintains his life in this city by relying on the meager income from delivering express delivery. But recently, he encountered a big problem - his landlord suddenly informed him that the rent would increase significantly next month, which doubled the pressure on Li Yang, who was already financially stressed.
After work that day, Li Yang dragged his tired body back to his small rental house. When passing by the garbage station in the community, he accidentally caught a glimpse of a worn-out backpack. The zipper of the backpack was half open, and something seemed to be glowing faintly inside. Out of curiosity, Li Yang walked over, picked up his backpack, and took out an old mobile phone from inside. The casing of the phone was badly worn, but the screen exuded a strange light, as if there was a mysterious force attracting him.
