The largest forces in the Martial Arts World were all preparing to make their moves, and so were the other sects.
Each of the Six Great Families had representatives there. Xiao Chuo brazenly came with the people of Du Gu Family, ostensibly to besiege Su Xin, but in reality, they were there to support and aid Su Xin.
Besides the Six Great Families, all the sects from the Seven Powers were present, except for the practically extinct Beggar's Sect.
In fact, the strength of the Seven Powers wasn't very formidable, and their ties with Su Xin were too deep, so initially, they did not want to come.
But now that Su Xin had become the public enemy of the Martial Arts World and all major sects were preparing to move against him, it would have been strange for the Seven Powers not to show up, and they would have easily been criticized by others in Jianghu.
