After the banquet came to an end, Ji Ning led Nuwa and Subhuti out to begin assembling the formation! Ning's Primaltwin had already assembled roughly 90% of the formation, and it only really needed the powerful castle to merge together with the formation and become its core and command center. This would allow the power of the formation to skyrocket.
No one save for the Autarchs would stand a chance at breaking apart a formation like this. Even the most powerful Sourcewalkers like the Blazesun Ruler would probably find it very difficult to breach this formation. It could be described as truly impregnable!
