The old lady Nan Qianfang didn't cast her Inner Core level power but the Awakening level power. She was purely casting the skill with her Yuan Shen; however, the skill she had cultivated was incredibly abstruse — the mountain god Yuan Shen had four arms, each of which had an eye, with each of those eyes having cultivated a sword ray.
The sword rays were formed by countless Sword Qi that interlinked together like gears to form a pillar that whirled around and slashed apart anything that stood in their way!
If it were only four punches, Zhong Yue would have been able to handle it by shielding himself with the Golden Crow wings, but these four Sword Qi was not something that his Golden Crow wings could withstand.
