Liu Ming's eyebrows raised slightly as he suddenly sensed four spiritual pressures at the peak of the Condensing Liquid stage coming from not far ahead.
After a moment, a patch of gray fog appeared in front of the hall. Amidst the undulating mist, four tall figures could be faintly seen charging towards him.
Liu Ming's eyes narrowed, and he saw the figures clearly. Those four tall silhouettes were actually humanoid skeletons.
Each skeleton was over two zhang tall, with coarse, blanched bones exposed, emitting a continuous flow of green light from their eye sockets. As they breathed in and out, strands of white Yin energy could be vaguely seen fluctuating.
These four large skeletons were standing in a seemingly irregular square, which was faintly some kind of strange battle array.
However, if that was the case, then breaking one would surely diminish its power tremendously.
