Yao Xuan continued onward.
The pale blue wind mist winding along both sides of the passage grew increasingly dense and pure, while the origin energy carried within the wind became frighteningly refined!
It was far beyond any ordinary wind-attributed battle qi found in the outside world.
After a moment, Yao Xuan finally reached the end.
An ancient stone door over three meters tall stood directly before him.
Yao Xuan raised a hand and lightly pressed it against the stone door, releasing a trace of battle qi from his palm.
There was none of the heavy resistance he had expected. Accompanied by a deep, muffled rumble, the thick stone door slowly swung inward, fully revealing the world beyond.
An incomparably grand, boundless stone chamber abruptly came into Yao Xuan's sight.
This chamber was vastly larger than the passage outside, so immense it seemed nearly endless!
Yet the chamber was completely empty, devoid of even a single treasure.
Other than its cold, ancient stone foundation and rock walls, there was nothing else within it.
A faint blue luminous mist filled every corner of the chamber. Extremely pure wind-attributed origin energy flowed slowly through it, thread after thread, endlessly and without interruption.
The concentration of wind elements here was several times greater than it had been in the depths of the passage. It was an exceptional sacred ground for wind-attributed cultivation on the Battle Qi Continent.

Yao Xuan nodded slightly, his gaze piercing
