Why Am I Always Short of Money?

[System+book-traveling+villain+single heroine+superpower+cool article] My name is Lu Chen, from Blue Star. Not long ago, I passed through the book and became an inconspicuous subordinate of a villain lady. In order to survive and avoid being blamed by the protagonist, I decided to leave this arrogant and beautiful young lady. So I worked hard, made a lot of money, and secretly set up a small business. Everything was ready, I asked the eldest lady to leave, and she agreed without blinking. After I left, a system bound me, asking me to collect rent on time every day, otherwise something bad would happen. I have no choice but to start my life as a rent collector. The common school beauty, the cold-blooded CEO, all have to pay me, and you, a damn girl, just work for me to pay off your debts when you go bankrupt. By the way, are you the protagonist? There was a dragon who just came to my factory to work illegally. If you don't come, your good brother Ye Fan won't leave a place for you. However, how come I am so rich, why does the system still prompt me that my balance is insufficient?
