Gu Li and the other high-ranking officials of Green Bamboo Stronghold felt the rapidly surging aura from Xie Ziyun and couldn't help but exchange surprised glances, secretly astonished.
This sign was exactly that of a Martial Artist at the crucial stage of breaking through and advancing.
When the aura on Xie Ziyun had climbed to a level comparable to that of a Cosmos Level Martial Artist, his body quivered lightly as if struck by lightning.
Moments later, that powerful aura quickly subsided, and in an instant, he returned to calmness.
At this time, Xie Ziyun, with his eyes tightly closed and expression solemn and dignified, was like an Old Monk in meditation, surrounded by faint wisps of Essence Energy.
This Essence Energy was pure and rich, containing powerful energy, something only a Cosmic Level Expert would possess.
