Xu Changqing did not slow down, following the aura all the way as he sped onward.
When his gaze swept over the scarred and battered land below, he could not help but sink into thought.
In the present Heavenly Origin Realm, Water Qi was thin while Earth Qi had turned turbid. As the saying went, mutual generation and mutual restraint—thus, the remaining three types of qi, metal, wood, and fire, were also declining day by day.

That way, as long as Water Qi stabilized, Wood Qi could gradually stabilize as well.
