Siheyuan: the Whole Family Supports the Construction of a "Leave Me and Guard" Courtyard

After crossing the Qinman Courtyard, I became the fifth eldest brother, Chen Hongbing. His father was an engineer and went to support construction. One of his four brothers became a soldier and the other three went to the corps. My mother and I are the only ones left at home. Yi Zhonghai usually doesn't mess with the engineer's family. The perfect genius training system is bound to the beasts in this yard, and I will play with you one by one!
