The corridor had reached its end.
A towering dark red wooden door slowly creaked open, revealing the pitch-black world outside.
Su Shijun tightened her cloak and, following behind Gongsun Bing, stepped through the door and ascended to the highest point of the Black Prison Castle encircled by battlements—the outer tower.
Looking out, the skies were dim and the horizon vast. Above, an empty and desolate world stretched out, occasionally punctuated by twisted arcs of lightning that flickered fleetingly in midair, faintly exposing the oppressive aura of the Guardian Arrays suspended there.
Beneath their feet lay dense Rune Arrays interlinked with each other. Far off in the Base Castles stood several towering figures, reaching heights of hundreds of meters. Their broad backs faced the tower, and from where Su Shijun stood atop the tower, she could only see the glowing halos encircling the backs of their heads.
They were the Big Wizards stationed at the Base Castles.
