Siheyuan: Sister Huairu, You Also Want to Be Happy, Right?

Traveling to the world of courtyard houses, Cao Shuang's life ushered in a wonderful turning point. He was lucky enough to get a magical system called "Mystery Shop". In this system, there are a wide variety of products, and the prices are not only staggeringly cheap, but also of high quality. Every purchase is a surprising experience, as if opening a door to a world of treasures. What's even more exciting is that as the number of accumulated purchases increases, he can continue to unlock mysterious rewards. These rewards are either rare items or unique skills, making his life in the courtyard a breeze. For example, when facing Aunt Huairu's visit, he said with a bit of ridicule: "Aunt Huairu, you'd better come back tomorrow night!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
