Everything started from an unexpected invitation that the twins received.
On the first day of May, in the Fairyland Pavilion of the North City, commandant Zhong Heng invited the master of the Horned Dragon Society, Shangguan Fei, and the master of Kun Society, Shangguan Ru, to a gathering.
There was an unspoken rule on the invitation: the master of the society could only bring one servant. This was verbally delivered by the officer who sent the invitation.
This invitation was unexpected because the commandant occupied a sinecure post. He had never interfered in the battles of South City. Moreover, on the surface, the twins had looked like they had reconciled. They wouldn't need an authoritative figure like him to resolve their rivalry.
Surprisingly, the twins rejected the invitation unanimously. The Stone Castle soon sent men to remind the Ninth Young Master and the Tenth Young Master that it would be better to go to the gathering at Fairyland Pavilion.
