A Ten-Billion Black Card from the Start, but Spending Money Makes Me Stronger

Lin Feng is reborn in 2020 with 87 yuan in his bank account and 8,600 yuan in unpaid tuition. The Godlike Tycoon System activates, and a black card loaded with tens of billions arrives. The rule: spend it all within 24 hours. The programmer's first reaction: find a bug. He transfers money to his younger sister, then has her transfer it back. The System counts it as spending, resetting the timer, while every last yuan of the tens of billions is returned. The System patches the bug, so he buys a shopping mall outright and invests in a loss-making venture, getting 50% of his principal back while keeping the rest. The System upgrades again: sign in for seven consecutive days to get triple cashback. He earns 20 billion in a single day. The System goes crazy and issues an impossible task: spend a trillion within 24 hours or lose two trillion. He moves the money around to avoid the penalty. The thicker the patches, the deeper the loopholes. He unlocks the ultimate rule: investments that lose money always return 50% in cashback. He becomes a perpetual-motion machine that prints money. The more he loses, the more he earns.
