The ten great sects had never been truly at peace. They kept fighting each other, trying to eat each other up and unify the entire Devil World, but no one had been able to do it.
In fact, the disciples of the top ten sects didn't know that the most important reason why they had become like this was that someone had incited them. It wasn't a single person, but an organization. However, this organization was very secretive and no one knew about it.
These people were the same as the demonic Sword Saint. They were also watching the people from the devil World. Their main goal was to prevent the devil World from being united.
