The sword light shone brilliantly, piercing the elder's back in an instant, making it appear as if the elder himself was moving forward.
"Ah!"
The elder let out a miserable cry, a large hole appearing in his back, with an expression of disbelief in his eyes.

"Bang!"
But for some unknown reason, the elder's physical body was much stronger than usual demons, with extremely vigorous vitality. Even with a large hole in his back and his internal organs scrambled by the Sword Qi, he remained alive.
"Zheng!"
Gu Yuan maintained a calm expression, once again urging the Boundless Sword Seal to unleash eighteen sword lights simultaneously, aiming to decapitate the elder.
"Bang!"
