This was especially true for his fourth brother, Qin Jinghong's two sons. After all, the children of his two older brothers had lost their fathers when they were young. They were not as confident as these two children.
As for his fourth brother, because he was the youngest child in the family, he had been very favored by Old Master Qin since he was young, which was also Qin Fangde's father. He was a strong competitor for the position of the family head.
Even when he was crippled later on, he always believed that it was Qin Fangde who snatched away the position of the family head that originally belonged to him, causing Qin Fangde a lot of trouble.
Under his influence, his two sons naturally had the same thought. They felt that the position of family head should have belonged to their father.
