Within this Jade Fold, the entire Twelve-Story Tower Grand Formation was classified as a sixth-tier formation.
What did a sixth-tier formation mean?

It only reached the fourth tier because the sun and moon's rotation was linked to the other formations within the Twelve-Story Tower, especially those in the White Jade Capital section.
