I Achieve Financial Freedom by Tipping Myself

Wang Shang, a struggling author who loves writing web novels, returns to the time of his college graduation, bringing along the full-refund System from the urban rebirth novel he wrote. It refunds the protagonist's daily expenses in full. Wang Shang thinks, I know this System inside out. It's basically a way to spend money every day without actually paying for it. That means he can tip his own novel without spending a cent, too. So achieving financial freedom is easy: just keep tipping your own novel every day, and earning a few tens of thousands a month is no dream. P.S. This is a slice-of-life story. The novel is just a tool for making money. P.S. Also known as: After Being Reborn, My Savings Only Go Up; After Being Reborn, I Can't Spend All My Money.
