The Hollow Void Practitioners closely followed behind the four guards, relentlessly pursuing them.
This battle had completely taken them by surprise.
With their expectations, having so many at the Great Perfection of Hollow Void and armed with so many powerful Spiritual Treasures, joining forces should have subdued even an ironclad opponent.
However, the outcome of the battle shocked everyone.
Dozens against four, yet their own side had lost three men and nearly twenty were injured, including many with serious injuries who, even if they survived, would suffer greatly diminished strength.
Not a single one of the four opponents had died!
More importantly, this battle had cost their side countless magical treasures, even shattering many Spiritual Treasures!
