This world-shattering sword could have directly split open the gates of Demon Eye Ghost City, but at the position where Zhang Menglong set up the formation, it was forcibly blocked. A blue curtain in the sky flickered constantly, showcasing the power of this Immortal Slaying Formation.
"Good!" Demon Eye shouted, "This Immortal Slaying Formation is indeed formidable. With Brother Zhang on our side, we might still have the strength to fight!"
Previously, the Ghost Kings who had underestimated Zhang Menglong because of his youth suddenly changed their perception of him. Blocking that sword, regardless of the method used, was already far beyond his capabilities.
"Everyone, although my formation is powerful, it requires a vast amount of Soul Cores. Without enough Soul Cores, this formation is like an empty shell. Just to be safe, the more Soul Cores, the better, so..."
"Brother Zhang, how confident are you?" asked the Ghost King named Ling Xu.
