The fourth disciple had not attacked maliciously. While the power of his attack was lethal, the sword master ensured it wouldn't strike any of Warden's critical organs.
The attack struck his lower body. And, as he had thought, Warden did not feel a thing. With [Absolute Invulnerability] triggered, he didn't have to worry about anything. While he couldn't feel any pain from the attack, Warden did manage to gauge the intricacies of the attack from a very close range. Not to mention, that attack wasn't completely directed at him.
Most of its force went beyond his form and bit through a huge chunk of the mountain, creating a large crater.
The upheaval in the wind calmed down as Warden found the fourth disciple standing with all his energy and stamina drained out of him. He didn't even lift his sword, much less attack for another chance.
Warden grinned and took a step forward, the spear in his hand.
"Any last words?" he asked, raising his spear.
