She transmigrates into a book as the true heiress who has just been brought back to a wealthy family. With an eight-hundred-million-yuan dowry, she has no trouble finding a husband, even with a son whose father is unknown. But in the original story, the true heiress is a vicious supporting character bound to a Spendthrift System. She soon squanders the family fortune and dies in disgrace, hated by everyone.
Since she has to spend money, she decides to fulfill the vulgar dream she had in her previous life as a frugal wage slave: buy houses and land in the capital, and find a well-paid job with little work near home, where the boss does nothing but hand out pay and approve leave.
What? It's hard to find a boss who's generous and clueless? Then she'll spend her own money to become that boss. She'll hire a bunch of employees in need and pay them to do nothing. She can happily watch them slack off while she meets her spending quota.
To her surprise, her haphazard business takes off. She doesn't even manage to spend all eight hundred million yuan, and instead brings in tens of billions more.
The more money she spends, the more she earns. The Spendthrift System is reduced to tears.
