Because Wu Mo discovered that Wang Yang seemed particularly interested in matters concerning demons and ghosts. But that was normal; after all, it's common for children to be curious about such strange and bizarre things.
So Wu Mo often recounted these stories.
And in Wu Mo's stories, it was the True Person of Qingcheng Mountain, who was slaying what kind of ghosts in which places; these stories were interesting at first, but they felt quite repetitive after a while.
As for Sword Qi and Sword Intent, perhaps even Wu Mo himself did not know what they really meant when he was talking about them.
But in some of the stories that Wu Mo told, he mentioned how a single Sword Qi cut through several large trees and a small mountain.
In the eyes of a mortal like Wu Mo, that was naturally earth-shattering, but it was nothing in front of him.
After all, even though he was just a Divine Thought now, his actual body was that of a Saint.
