Gao Zhendong transmigrates into the world of Siheyuan (The Courtyard). As a newcomer to the quadrangle compound, he boasts an impeccable background: an exemplar of revolutionary pedigree, physically robust, strikingly handsome, and battle-hardened from military service where he earned repeated merits. With advanced university education, technical expertise, ample funds, and a system at his disposal, he possesses both the wisdom of his past life and the system's guaranteed resources—occasionally enhanced by futuristic insights from lucky draws.

Rejecting trivial pursuits and petty squabbles over trifles, he aspires to contribute meaningfully in this zealous and vibrant era. At the very least, he wishes to declare in his twilight years: "These two lifetimes have been worthwhile."
