Transmigrated to the 1970s, I Build a Fortune Worth Billions

{Siheyuan courtyard + transmigrate to another era + cherished by the whole family + mysterious big shot + sweet military romance + strong hero and heroine + building a fortune + adorable twins}

A jade pendant gave her a spatial golden finger, and a dream foretold that she was about to transmigrate to the 1970s and reunite with her family. After transmigrating, she became the family’s darling once again. With a space and supplies at her disposal, she was determined to lie flat and live lazily with her family. But somehow, while lying flat, she became a billionaire, and a mysterious big shot nearby had his eye on her.

(A purely sweet romance, with very few oddballs, who will be dealt with quickly. The main focus is on being cherished by the whole family. The heroine does not go to the countryside. The hero appears quite late: he first meets her at a sports field, and they only properly get to know each other after she graduates from high school.)
