Prisonworld 17.
Whoosh! Whoosh! Whoosh! A series of white-robed figures flew through the region of primordial chaos, entering the vast prisonworld. A total of sixteen white-robed figures levitated in midair. All eighteen of Ning's clones had entered the prisonworld now.
"Before I go to Undermoon Lake, I need to complete certain careful preparations." Fifteen of the sixteen white-robed youths instantly vanished, leaving behind only the one with the Ninehorn Lightning Serpent.
Whoosh. An enormous black lightning serpent streaked through the skies, rapidly flying off into the distance.
