Background / History

Bai Ye summoned the Doppelganger during his confrontation with the Palace Attire Woman in Dust Star Valley. The two bodies attacked in concert, using overwhelming sword light against their opponent; they continued fighting in unison until Bai Ye killed her with the Reincarnation Killing Sword 91 92.

The Doppelganger conducted repeated explorations of No Man's Land and its ancient ruins. Within the abandoned Reincarnation Dao Sect, he acquired the Samsara Immortal Mirror.
