However, [Iron Will] does not operate out of thin air. Anything that is not strong enough is easily kept out; the intensity of this current situation is somewhat too high, requiring Gu Hang, the host, to provide more abundant Spiritual Energy as the source for the [Iron Will] ability to exert a greater effect.
But the problem is... Gu Hang doesn't have any left.
He just finished a battle and is in a state of spiritual energy depletion.
If that were not the case, he would not have been so easily vulnerable in the first place.
Nevertheless, after [Iron Will] took effect, Gu Hang felt the soul pain alleviate significantly.
Although it was still painful, at least he could think now.
And the first thing he thought of was: If this continued for about another two minutes, he would die.
The next thing he needed to consider was how to save himself.
Normally speaking, there would be no way to do so. With his spiritual energy drained, what could he possibly do?
