If Wang You hadn't explained explicitly what Yin-Yang Imperial Palace and Star Illuminating Palace were planning to do, the casual tone of the conversation would have made it seem as trivial as changing a tablecloth on Lin Chuan Plain.
This intrigued Wang Chan immensely: How could a mere Demon King from a millennium ago warrant such a grave treatment by the Tianan Wang Clan?
Buddha's Country would fight for faith, Divine Court would fight for doctrinal succession, and Xu Clan would fight for personal grievances. Through the ages, the Wang Clan has always fought solely for benefits.
These benefits were not narrow self-interests, but those serving the group's advantage. Given the opportunity, the Wang Clan would even encompass the entirety of Xiehe within its fold.
Of course, in the process of maximizing these interests, Tianan Wang Clan must occupy the richest portion—that's the strategy of union and negotiation of the Tianan Wang Family.
