Xiao Tianrong's face grew somber after listening to the Great Elder's words. His intuition told him that this matter was far from simple. To kill someone at the Human Immortal Realm Peak in an instant meant that only someone at the Earth Immortal Realm Middle Stage or above could have done it. This suggested that there might be a loose cultivator above the Earth Immortal Realm Middle Stage secretly assassinating the expedition force members within the Divine Origin Cultivation World!
As he thought about it, Xiao Tianrong became increasingly convinced that this was quite likely. In a medium-power Divine Origin Cultivation World, the Sect Ancestor was at most at the Earth Immortal Realm Middle Stage. But the problem was, in any cultivation world, the strong figures of the Earth Immortal Realm were the most important people within the sect and generally wouldn't leave their sect.
