I Went to the Supermarket in the Courtyard

(Siheyuan + age + rebirth + happy family + daily life in the compound + lots of fun) Liu Jianye was reborn in a small rural area in the 1960s, but he was different from others. He has all the memories of the mercenary king in his previous life, and there is also a large supermarket across the ages in his mind. The supermarket has a one-cent flash sale on the first day of every month. From then on, his goal was to make money, buy things, live a good life for his family, marry a beautiful wife, and have no worries about food and clothing. No food at home? Purchase! A penny robot dog? Purchase! A penny body armor? Purchase! High-tech exoskeleton protection? Purchase! ... Others are still planning for life, while his supermarket has endless supplies. Life is supposed to be so plain and fun!
