Shen Tian and the rest fell into deep thought as they gazed upon the skeletons battling at the bottom of the mountain.
These soulless skeletons were the main battle targets of this trial for the disciples from the two sacred grounds, six grotto-heavens, and 12 blessed-lands.
They were the defeated fighters from the major battle during the Primordial Age.

It could be said that most of the Foundation Establishment cultivators would have no advantage over these soulless skeletons.
They could be killed if they displayed a single moment of carelessness.
