Siheyuan: the Old Wolf Returns to His Lair and Specializes in Treating All Kinds of Dissatisfaction

[All villains + no system + scheming + father and son teaming up + heroes of the era] In the winter of 1965, the old wolf Xu Fugui, who had been away from the courtyard for many years, came back. Looking at his son Xu Damao, who had his pants taken off by Silly Zhu and hung on a tree, and could only cry for father and mother, Xu Fugui slapped him in the face: "The Xu family's offspring will either be meat-eating wolves or guard dogs, but they cannot be pigs left to be slaughtered!" From this day on, the situation in the courtyard changed. Silly Zhu's lunch box was smashed, Yi Zhonghai's moral integrity was broken, the deaf old lady's crutch was broken, and Qin Huairu became the sharpest knife in the Xu family's hand. ​Xu Fugui taught his son: "Da Mao, remember this. When you are a dog for a big shot, you have to learn to keep a chain for yourself; when dealing with hypocrites, you must be better at acting than him; when dealing with real villains, you must be more ruthless than him!" From the intrigues in Nanluoguxiang, to the ups and downs of the great era, to the godfather of capital in the ups and downs of the business world. Let's see how the most ruthless father and son in the courtyard climb to the top step by step, stepping on the bones of birds!
