Funds expire if not spent within 24 hours; billions of yuan in one day
The protagonist possesses a black card that disappears if not used within 24 hours. Starting with 2,000 yuan, these funds have grown to billions of yuan thanks to a system that refunds 10 times the amount spent.
Due to the 24-hour time limit, Lin was forced to spend billions of yuan in a short period. He planned strategic spending under this pressure.
Lin went beyond simply spending money, attempting to increase his assets by investing in various sectors such as real estate, luxury cars, and legal services.
