Wen Yunshan's face turned pale. He had exhausted every ounce of his profound energy with the earlier attack, but it failed to break through Yin Su's windstorm. He staggered backward and fell on one knee, looking at Yin Su unwillingly.
"Brother Shan!" Hu An shouted anxiously and came to Wen Yunshan's side.
"Go. Use the thirty-six swords formation." Wen Yunshan uttered in difficulty.
Hu An's eyes flashed with determination. He hurriedly went to find his fellow brothers and shouted. "Brothers, let's do it!"
The other eight Eternal Sword Sect disciples quickly banded together and formed into an octagon shape with Hu An at the center. A sharp sword aura instantly filled the air, causing Yin Su to squint his eyes slightly.
"Interesting…" Yin Su licked his lips. He clapped his hands together, and the surrounding windstorm abruptly shrank by half, forcing everyone to crowd together at the center.
