Traveling back to the cold winter of 1958, Hao Dali is reduced to a refugee wandering the streets of Beiping (Four-Nine City). Awaken to a survival system with a strict, life-or-death order: he must move into the No. 95 Rolling Mill Workers' Quadrangle Courtyard, or be obliterated by the system upon timeout. With nothing to his name, his only option is to marry into the Su family as a matrilocal son-in-law. Surrounded by malicious, scheming neighbors eyeing him hungrily, he must rely on the Su family's protection to take root in the courtyard. In an era of scarce supplies, he relies on system rewards to survive step by step, outwitting the various malicious beasts in the courtyard and embarking on a path of counterattack in that era.
