Siheyuan: Don't Mess with My Sister

Li Youcheng travels through the courtyard. He seems weak and can be bullied, but in fact he is bound to the chaotic small world system and is a hidden boss. The medical skills handed down from ancient times can save lives and heal the wounded, the small world can produce endless food and meat, and taking care of his sister is his bottom line. Faced with Jia Zhang's arrogance, Yi Zhonghai's calculations, and Xu Damao's bastards, he never took the initiative to cause trouble, but he was never afraid of getting into trouble. He would slap him in the face and do things neatly. He silently protects his sister and secretly makes money until he amazes everyone and becomes an invisible boss that no one in the courtyard dares to mess with.
