Chen Yu was an ordinary city worker, down in the dumps after his girlfriend dumped him. Then, out of nowhere, he activated a tenfold cashback System.
Now he's rolling in it. Whatever he spends, he gets ten times the money back. And spending money on girls is a no-brainer: he just spends, then waits for the cash to roll in.
[Spent 200, System returned 2,000. Money received.]
[Spent 5,999, System returned 59,990. Money received.]
[Spent 2,000,000, System returned 20,000,000. Money received.]
When he runs into people trying to swindle him, Chen Yu goes straight on the offensive.
You might make a little profit, but I'll never take a loss!
