Spend a Billion, Become the World's Richest?

[Wish Fulfillment + Good Luck + Tycoon + System] After completing her abused heroine assignment, Ye Suisui planned to make a beautiful exit from the world at her wedding. But the System malfunctioned, leaving her unable to return to reality. To get home, Ye Suisui had no choice but to accept another task from the System: spend one billion and return to the real world. From then on, Ye Suisui led a life of spending money like water. She had only one rule for spending: if it wouldn't lose money, she wouldn't buy it. But it seemed the heavens were determined to thwart her. She casually bought a hotel to spite her scumbag ex's first love, and its stock price just kept climbing. She invested in a science fiction film, and its box office soared to become the highest-grossing movie in history. She casually saved a company on the verge of bankruptcy, and it went on to become one of the world's top 500 companies. Everyone called her the Warren Buffett of the investment world. Even her scumbag ex couldn't help coming back to beg for reconciliation after seeing her success. But only Ye Suisui knew how hard things were for her. Looking at the endless string of zeroes beside her System, all Ye Suisui wanted was to drop dead on the spot. When will this life of spending money more slowly than she earns it finally end?
