He shared the vision of the Green Reed Sword. Three years ago, when he ascended to a True Immortal, the Green Reed Sword pulled him back to the Ancient First Era, to witness the battle of the Interception Sect. At the last moment, the Tongtian Sword Sovereign threw the Green Reed Sword into a fragmented piece of Reincarnation. The Green Reed Sword split into numerous Divided Swords, scattering across the Nine Realms.
Moreover, that piece of Reincarnation wasn't just an ordinary piece from the Immortal Realm, but a fragment from the Great Reincarnation of the Ancient World.
Before Han Yi became an Immortal, he had learned about Reincarnation in the Xuancang Palace because it involved the Chaotic Demon Area and Yuan Shun.
