Willpower was after something that existed in the foundation of a body. Once the body declines and dies, the willpower will also slowly diminish, unless it was like the swarthy youth, whose soul had been refined into a Yin specter before losing his body. His life was no longer a combination of body and soul. A Yin specter's ghostly spirit resides in a piece of flesh. Under these circumstances, the swarthy youth's soul could exist even after leaving a physical body.
A normal human would have fuzzy willpower when seriously injured and they might even fall unconscious.
The swarthy youth did not dare to clash with Lin Xintong directly with willpower, but he could severely injure Lin Xintong's body, making her lose her consciousness.
In the icy plain, the snowy wind was ceaseless. Lin Xintong needed to constantly use Yuan Qi to protect her body, but having gone so deep, most of her Yuan Qi was depleted.
