During the Emperors Era the Divine Beast Realm's disciple was a powerful contender for the Heaven's Will, but eventually he was defeated by Hong Tian. Unconvinced by his defeat, the Divine Beast Realm encouraged all the sects in the Stone Medicine World to ambush Hong Tian who had yet to ascend to Immortal Emperor. All the most powerful lineages in this world were involved in this terrible ambush, including the Alchemy Kingdom, the Jianlong Clan, and the Beastmaster Citadel as well as other imperial sects.
