This is also the case in the Blazing Flame Tribe. Ever since the Blazing Flame Tribe was elevated to a upper-class tribe, women from vassal tribes rushed to marry into Blazing Flame.
With this thousands-of-years-old tradition of marrying within the tribes, even the mother of Lord Jishan might possibly have come from one of the upper-class tribes.
From top to bottom, relatives are connected, and it's really difficult for Lord Jishan to sever ties. He must consider family sentiments, despite external relations.
This is also a common problem faced by tribes with long histories.
By relying on marital relations with Bo Division, facing the decrees of the Jishan Bo Division, upper-class tribes directly gathered clan soldiers from their vassal tribes and sent them to heed orders at the Jishan camp.
The decrees of the Bo Division must naturally be strictly followed. Aside from additional clan soldiers from the lower-class tribes, sending a squad of elite clan soldiers will suffice.
