She Takes a System to the 1980s and Becomes a Newly Rich Tycoon

Looking for Stories About Overseas Chinese Returning Home to Find Their Families. Male or Female Leads Are Fine, as Long as They’re Powerful, Wealthy, and Scheming

I don't care too much whether the protagonist is good or bad. I'm looking for a book where they gradually rise in status in a poor era by using a System sign-in feature or something like that ^_^
