This matter traces back to the banquet the day before yesterday when Brown Kress and Brown Lya crossed Situ Xin. Situ Xin immediately phoned Xia Yujie back in Country H, asking him to utilize the Dragon Society's influence in BL to give Brown Kress and Brown Lya a proper lesson, showing them that not everyone is to be trifled with. The ideal outcome would be to dethrone Brown Kress from his current position as the head of the Brown Family.
Situ Xin made the call to Xia Yujie partly out of habit; despite her status as the Dragon Society's Young Miss being equal to Xia Yujie's position as the Dragon Society's boss, she always went to him when she needed the Dragon Society's assistance with a problem. Situ Xin also had contact information for the Dragon Society's branch leaders in BL, but still, she preferred to work through Xia Yujie.
