The Great Emperor said that Shuhang should try it again. Was he talking about creating a resonance between the ❮World-Destroying Divine Beast Technique❯ and the ❮Thirty-Three Divine Beasts' Technique❯?
How was it supposed to work, though?
Was he supposed to use the 'Whale Swallowing Technique' to devour the spirit beast crystals and then inject true yuan into cultivators of the Black Horse Branch? After that, he would get the cultivators of the Black Horse Branch to use the ❮World-Destroying Divine Beast Technique❯ and the secret book at the same time, and then somehow acquire the 'auxiliary book' hidden in the secret book with the combination of the two?
But such being the case, there would be quite a few inconsistencies.
To get the 'auxiliary book' from the Human Alliance, he would have to master the 'Thirty-Three Divine Beasts' Technique'.
