The excuse for rebellion that Provincial Governor Lan Tiankuo lost due to being assassinated by Yue Hongling suddenly appeared again.
Clan Leader of the Black Miao, Lei Zhentang, issued a call for heroes at night, inviting all clans to gather in Dali.
The message was that since the Xia people had killed his son, no one else could escape their fate either. Why not unite and rebel?
Everyone knew this was just an excuse, but an excuse was needed.
