By finishing the Undying Codex to the Great Circle of Undying Blood, the cultivator can start practicing the Live-Forever Codex. Once he reaches Live-Forever God, the two codex will resonate and combine. If they are successfully fused together the cultivator can be considered the true inheritor of the Arch-Emperor Dynasty's Undying Live-Forever Technique and will be called Arch-Ancestor.

The only one to have fulfilled the requirements was Arch-Ancestor Bai Xiaochun.

Bai Xiaochun's Codexes

The original two codexes of the Undying Live Forever Technique paves the way to Mahayana. However once one becomes a Heavenly Lord one must follow a self-created path. Because of that, Bai Xiaochun must create one new codex for each big realm starting from Mahayana.

The first codex created by him is the Everlasting Codex (亘古卷), thus renaming the Undying Live Forever Technique as Undying Live Forever Everlasting Technique.

Time Immemorial Codex

The third codex of the technique, created by Bai Xiaochun after reaching Mahayana as his self-created path towards Archaean realm. The goal of this codex is to let the Dao Seed to germinate and bloom into a flower of Dao Will.

It is divided in three levels, once all three reaches great accomplishment one can breakthrough to Archaean realm.


  • The Undying Live Forever Technique is directly linked to the Dao of Time. The Undying Codex represents regeneration and restoration, and the Live Forever Codex represents longevity. Bai Xiaochun's third codex, the Time Immemorial Codex, represents past, present and future.
