Dozens of people around were initially somewhat confused, as they had just been undergoing trials on the mountain path moments ago, only to inexplicably find themselves in the martial arena.
In the trials of the Dream Shadow Cave spanning thousands of years, there seemed to be no such challenge.
However, upon seeing the Soul Heartstone, everyone immediately sobered up a bit. It was undeniable that this Soul Heartstone was indeed an extremely precious natural treasure.
It was one of the few spiritual materials that could be used by martial practitioners in the Combined Aperture Tempering realm.
Other spiritual materials that could enhance spiritual power were either too powerful, causing the untransformed spiritual consciousness of the Combined Aperture Tempering realm to be unable to bear it, or they were too precious, even the Mountain Sea Realm would fight over them, let alone share with Combined Aperture Tempering realm martial practitioners.
