Reborn in 1973, Returning Home with Billions in Capital

The 1960s and 70s, Unlimited Supplies, Male-Oriented Fiction, Not Female-Oriented

Looking for male-oriented novels where the male lead transmigrates to the 1970s or 1980s with an unlimited supply of goods. Traveling back and forth between eras is fine too.

A Great Novel About Transmigrating to Hong Kong

The male lead transmigrates to Hong Kong. Although he has a System, it plays only a minor role. He mainly uses his knowledge from the future to stir things up in Hong Kong, and eventually across the world, taking on financial tycoons from multiple countries.

The 1960s, a Foreign Tycoon Returns Home to Find His Family and Help Build the Nation

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 ^_^

Stories Like Blood-Colored Romance, Rogue, and Courtyard Kids

Transmigration or fanfiction, either is fine. Thanks.
