After Li Wuliang died in the fight against the three factions, Black Cavalry Alliance sent out all their men to destroy lots of the subbranches of the three factions within two months. That was why when the three factions fought against Ye Xiao, they didn't have much support from the remote areas.
When Black Cavalry Alliance was going to fight head-on with the main force of the three factions, Shangguan Zhuifeng suddenly had a stroke. It all happened within half a day. The lower half of his body was disabled. Even though he was utterly furious, he couldn't make further attacks anymore. Black Cavalry Alliance temporarily lost its most powerful leader, so the revenge stopped.
