As for how to choose a successor, they naturally have their own set of selection criteria. Within the family's Elder Council, there is a supreme group known as the Highest Elder Circle, and the decisions made by this Highest Elder Circle are almost tantamount to decisions made by the entire clan. To put it bluntly, this Highest Elder Circle is very much like the cabinets of various countries on Earth.
This Highest Elder Circle is responsible for all aspects of the clan, and the Clan Leader is like the nation's leader. The only difference is that this nation is composed of family members. It bears some similarities to the feudal societies of ancient times.
However, the reason why such a system has not collapsed is due to their prolonged lifespans. When a competent individual serves as the Clan Leader, the clan can sustain itself for tens of thousands or even hundreds of thousands of years. During this time, the number of offspring naturally becomes a vast figure.
