Sign-In System: This Is the Stingiest Heroine I've Ever Met

Tang Rao stayed up every night reading novels and playing games. One day, Fortune smiled on her and she unexpectedly got bound to a Get Rich sign-in System. So excited that she suddenly died of a heart attack, she transmigrated to a parallel world and began a new life. The expensive clothes and shoes she once wouldn't even dare to look at are now hers to buy as many as she wants. She used to worry about making ends meet every day until her hair started falling out. Now, all she has to do is sign in to the System and complete its tasks, and she'll never have to worry about money again.
