The Death Code in the Back Mountain Cave

Transmigration to a Bygone Era

Looking for books similar to *1960: Transmigrating to Nanluoguxiang*. I want a period story with a System, where someone from a later era transmigrates to the 1960s. The protagonist is a parent with a family, and the story should feel grounded in everyday life. The protagonist shouldn't be a pushover, but should show kindness and humanity, and be filial.
