As the Grand Elder started filling Chen Fan in on what had happened in the past, a complete story finally started to surface before Chen Fan. The Witch Sects had many branches but the Dark Witch Sect had always been the leading branch. Many powerful overlords hailed from the Dark Witch Sect and remained unchallenged.
Three hundred years ago, the Great Magus of the Dark Witch Sect became a dominant force in China. Even if China was as powerful of a nation as it was now, it would have difficulties keeping the Great Magus in check.
The Great Magus sought medicine from the Medicine God Valley Sect, and in return, he had helped the Medicine God Valley Sect cast a Dharma Array over the valley and left a Dharma Treasure as gratitude.
