Modern chef He Yutian transmigrates to 1960, becoming a canteen chef at a steel mill in a courtyard compound and awakening a Portable Space System. During the three difficult years, he secretly uses supplies from his space to help the widowed Qin Huaiying and her family, cares for Granny Deaf, who has no family, and builds up prestige to upgrade his space. When his sworn rival Xu Damou repeatedly spreads rumors and frames him, He Yutian uses his wits and the power of his space to turn every scheme aside. He gradually establishes himself in the compound and earns the neighbors' respect, while feelings quietly begin to blossom between him, Qin Huaiying, Teacher Ran, and others.
