Purple Qi Valley was a notoriously deadly place, situated right at the center of the three great territories. The Human Territory didn't want it, the Demon Territory disdained it, and even the Demon Clan's Territory looked down upon it. Over time, Purple Qi Valley became a no-man's-land. Typically, if the three great territories needed to negotiate, they would choose Purple Qi Valley as the negotiation site.
Purple Qi Valley was shrouded year-round in a thick, purple mist that contained a deadly poison. Merely breathing it in could cause a cultivator's body to fester and die; even a Great Cultivator at the Transcendance Tribulation Stage would stay away. Once, someone had spent a century trying to study the purple mist, hoping to find a way to neutralize it, but failing in the end. Since then, no one had dared to challenge the purple mist.
No one knew how long Purple Qi Valley had existed, nor did anyone know how the purple mist had formed. Everything was a mystery.
