Siheyuan: Silly Zhu Reborn, Confronting the Vermin

Transmigrated into the year 1965 in a courtyard full of scheming neighbors. In his previous life, he was drained of money and food by the Jia family and the three uncles, living a life of frustration and oppression. After rebirth, he unlocks a portable fresh-keeping storage space, which cannot grow crops but can store supplies purchased with ration tickets and money. The protagonist changes his former timid ways, directly refusing anyone who comes to scheme for handouts. When Jia Zhang-shi throws tantrums, Qin Huairu plays the victim, Yi Zhonghai moralizes, and Xu Damao maliciously reports him, he confronts them all head-on. His main focus is working to earn money and stockpile goods, keeping supplies safe in the space; he plans ahead using his memories, waiting for opportunities in business or education to move out of the courtyard. No cheat-like wins, just space storage and diligent living. He never indulges the Jia family's bloodsucking, staying clear-headed and unwavering. If you like the old pushover protagonist, don't click. — Description from novelcodex.org
