Emperor of the Six Paths of Reincarnation

[Two male leads + invincible protagonist + wish fulfillment]

“The sixth incarnation on the final step to immortality begins with its soul split in two, then seizes the body of a powerhouse in the Emperor Realm. Though the main body is mortal, its comprehension and sword talent are monstrously exceptional, without precedent.”

Xuan Er is part of Xuan Yi's soul, split off from the whole, and has a mind of his own. Xuan Yi and Xuan Er share memories, but not talents or strength.
