By the Time My Ex-Girlfriend Regretted It, I Was Worth Hundreds of Billions

Lin Yu has just graduated from college and makes a living delivering takeout with his girlfriend of three years, Su Yue. After a hundred grueling days, they save 50,000 yuan and eagerly look forward to building a home together. But Su Yue looks down on him for being poor, runs into another man's arms, and takes their savings, leaving him with just 20,000 yuan and a cold breakup message. Lin Yu suddenly hits rock bottom, having lost his job, love, and money, and is plunged into despair. Just as he reaches the end of his rope, a multiple cashback System appears out of nowhere. Every purchase earns him a random multiple of its cost in cashback, with a minimum of ten times and no upper limit. At last, his fortunes begin to turn. With the System's help, Lin Yu easily resolves his rent crisis, learns to plan his spending wisely, builds his wealth, and steadily rises to the top.
