The power of the Sky-splitting Halberd was self-evident.
Throughout their journey, nothing could stand against its rapid cuts in the hand of Xu Mu.
Yet, this was not an apt demonstration of its true power; it was only being used like a regular weapon.
Xu Mu had never tapped into the real capabilities of the Sky-splitting Halberd.
The reason was simple: the Sky-splitting Halberd was a high-level weapon that Xu Mu was unable to refine.
According to the initial conversation among the puppets, the Sky-splitting Halberd was definitely used by the Immortals as an Immortal Artifact. It was ranked significantly higher.
The difference between a single stage of cultivation was already huge. Between several stages, particularly between cultivators and Immortals, the difference was nearly unthinkable.
Xu Mu had encountered three True Spirits, each of them inconceivably powerful. Yet these truly incredible True Spirits still lag far behind the lowest-ranked True Immortals.
