Siheyuan: From the Start, I Got a System with an Outrageously Generous Uncle

Jiang Chuyang transmigrates into the beast-filled courtyard and becomes the uncle of twin sisters. His elder sister's family is framed and sent to prison, leaving him and her two children to depend on each other. He binds himself to the “Badass Uncle” System and gets grandmaster-level traditional Chinese medicine skills and a portable space from the start. When he sees Jia Zhangshi bullying his nieces, he decides to “settle things” with his fists.
