The worsening condition of the different major powers when it came to facing off against the demonic cultivators didn't just have to do with the fact that they had been caught off guard by them following their swift response after the turmoil inside the Frozen Wastelands had subsided, but also had to do with the simple fact that there were far more demonic cultivators in the Demon King Realm ready to make a push forward while the Celestial Immortal Realm who would have normally stopped them were busy informing their seniors about what had taken place in the Frozen Wastelands. Rendering them unable to respond in time to the demonic cultivators.
Of course, this wasn't entirely due to negligence on their part, but also had to do with the fact that other demonic cultivators had managed to copy what Xuan Gui had done in the Blue Sea Empire and were now taking the chance to cause chaos behind the scenes.
