Despite the grandeur of the Duke Residence, it was mainly due to Zhou Gu's fathers and uncles who died young in battles, leaving the residence quite underpopulated. Establishing a household with military achievements requires a cost in blood. Zhou Gu's grandfather retired from the battlefield due to serious injuries, and his father and uncles were not so lucky, but fortunately, they had children before they died in battle, making the third generation appear more populous. Now they lived in times of peace, and didn't need to wage wars. His three brothers were in the military, but they were all fine. Among his parents' children, he has one legitimate elder brother, the current heir to the Duke Residence, Zhou Wei, and one legitimate sister. The rest are cousins left behind by his uncles, and there aren't many of them either. Including him, there are only nine offspring in the Duke Residence.
