Frost Monarch's facial expression seemed stiff. That was because he saw the space around him was being aligned with countless ice fibers crisscrossing all over each other, creating a seemingly inescapable area.
What worried Frost Monarch most was that his domain could no longer appeared in this area, meaning that he wouldn't be able to use his domain to protect himself.
If he had used his overpowering domain against Ling Lan and completely restricted Ling Lan's domain in the very beginning, then he wouldn't have been in this situation. The person who had control would not have been Ling Lan, but him instead.
Frost Monarch felt that something would go terribly wrong if he continued to stay within the area. He instantly turned himself ice particles with the intention of wanting to leave the area that was gave him an ominous feeling to his very core.
