Liu Chu gripped the longest treasured sword in his right hand and a medium-sized one in his left. With both hands crossing, he drove a fierce sword momentum madly at the weak point in the ice.
Before this, Lu Feng had embedded the Sky Supporting Token within it. A blazing golden pillar of light passed through the cluster of swords overhead and fell upon the designated spot.
