Siheyuan: Obtain Stealth at the Beginning

Fang Yuan's soul accidentally traveled to 1960 and became a member of the courtyard. As soon as he started, he was lucky enough to awaken the King of Assassins system, and also learned the magical stealth technique. Previously, Jia Dongxu was dissatisfied because he failed to pass the skills assessment, so he instigated a group of people with bad conduct in the courtyard to jointly exclude and suppress his predecessor. Under this endless difficulty and torture, the predecessor was overwhelmed and finally chose to hang himself and passed away with regret.
