My Siheyuan Life with a World-Saving System

Zhang Dongliang, a modern company boss, found his comfortable life shattered by an insistent, disembodied voice demanding an impossible mission: save a world teetering on collapse. His unwilling destination? The dreary, familiar yet alien Beijing of 1958, thrust into the midst of the notorious 'Love in the Courtyard' sitcom, years before its grim plot truly began. Surrounded by the era's harsh realities and treacherous neighbors, his biggest challenge seemed to be just surviving the biting cold, let alone an impending apocalypse. Fortunately, the voice belonged to Xiaodie, a fragment of the legendary Creation Jade Disc. This reluctant system granted Zhang Dongliang a personal 'small world'—an infinite storage space capable of replicating inanimate objects. He arrived younger, handsomer, and surprisingly wealthy, equipped with years of meticulously stockpiled resources, from white flour and fine liquor to hidden gold and military-grade supplies. This wasn't just survival; it was preparation for global catastrophe. But as he navigated the petty squabbles and desperate realities of the courtyard, witnessing the innocent Qin Huairu and the chaotic Shazhu, Zhang Dongliang realized his cosmic mission might be far less dangerous than the human drama unfolding around him. Could he really prepare for a world-ending catastrophe while navigating the treacherous waters of 1950s neighborly relations, or would the system's true demands push him beyond the brink?
