On Canglan Island, it wasn't just Demon Lord Huo Tu who was a peak Great Grandmaster; this had already been confirmed. As for how many peak Great Grandmasters were lying in ambush, that was unknown.
Even the identities of the other peak Great Grandmasters and the forces they came from were not known.
However, they were either from the black-robed faction or the demon cult faction.
As to whether a third force was involved, it remains unknown.
No matter which faction the other peak Great Grandmasters came from, to Xu Yan, there was no difference.
Just kill them!
Outside Canglan Island, on the Cang River, floated numerous small boats. Each boat was placed far from Canglan Island, but such a distance meant little to those powerful figures.
Each small boat carried a Great Grandmaster, all here to observe the battle.
