Business Management System: I Swear I’m Bound to an Ancestor [Western Fantasy]

Xu Youyou wakes up one day in a Western fantasy world. Fortunately, she is bound to a business System, and knows that as long as she has money, life is no different from living in modern society. It's just that the little System is a bit noisy, always hoping she'll earn more and spend less. How could she do that? Running a shop is exhausting. How can it deprive her of the right to enjoy herself? But how did the king end up being overthrown while she was busy running her shop? What do you mean it was all thanks to me? Don't make things up. I'm just a shopkeeper. As long as the money comes in, I'm happy.
