Siheyuan: Transmigrating Gets Me a Pocket Dimension, and My Aunt Invites Me to Dinner

Cao Shuang transmigrates to a courtyard in 1963 and takes his second uncle's place as a worker at the steel mill. The moment he arrives, Yi Zhonghai sets a trap for him, forcing him to support his distant relative, Qin Huairu. At his moment of desperation, Cao Shuang binds to a sign-in System, unlocking a portable space, a physique-enhancing potion, and rice and pork. He goes along with the idea of helping her, then turns around and dumps the problem of raising donations on the whole courtyard, taking on the worst of them with his own strength. To get the donations back, Qin Huairu invites him home for a meal, and Cao Shuang uses the opportunity to get the upper hand. With his storage space, he stockpiles supplies, protects his family's assets, and puts the troublemakers in their place. As he handles his aunt by marriage, he rises to become the courtyard's hidden powerhouse!
