He hadn't done much else.
Yet, there was indeed something strange.
During his daily cultivation, his speed was already extremely fast, rivaling the absorption rate of spiritual energy from the world around that was typical for the Ninth Grade Refining Void Realm.
However, considering he might be a Sacred Body, unprecedented in the world, it was understandable.
But...every time he finished cultivating, a massive amount of spiritual energy mysteriously appeared within his body, nourishing it and elevating his realm.
This baffled the True Monarch, who could not comprehend where this spiritual energy was coming from!
It was as if the energy materialized out of thin air!
Regarding Gu Changge's Root Bone in his eyes, it seemed at most the level of an Acquired Spirit Body, but he also discerned some clues and could tell that Gu had concealed his Root Bone.
However, just how much was concealed remained elusive!
His methods were indeed very clever.
