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."

Liu Minghui went back to 1957. In that era when material life was not very abundant, he successfully became a worker in a steel rolling mill and lived in a courtyard house by relying on the abundant space and materials.

It mainly tells the story of Liu Minghui's daily life in the steel rolling mill and the courtyard, with little violence.

Reborn in a siheyuan courtyard with a pocket dimension at my fingertips, I embark on a life of leisurely urban homesteading—raising fish, growing vegetables, cultivating ginseng; selling produce, trading fish, collecting antiques... All while quietly observing the ever-shifting dramas of courtyard life...

I'm a bit confused. I just went on a budget trip, how did I become a fool for no reason? Well! Since I'm here, I might as well make the best of it. At least I don't have to worry about eating bread every day. Although this era is materially scarce, the people of this era are simple and kind! The happiness index of life is high! ~Okay! Except for this man-eating courtyard and the beasts living in this courtyard~
