Once when Lei Luo journeyed into the Primordial World, he was possessed by purple shadow from Shadow Tribe, which then acted as a spy.
About a 100 years later, the Profound Heavenly Spiritslash Sword appeared. Many races started preparation for war to compete for the treasure. The possesion of it could attract a True Spirit-grade existence and cause it to protect their clan and turn it into the strongest tribe in the spirit realm. These True Spirit-grade existences are superior to Immortals from the True Immortal Realm.
