The aura around the two practitioners in the Circulation Phase was not extremely formidable. Still, they were shrouded in a spine-chilling, terror-inducing aura.
This aura was different from any power fluctuation and carried an unaccountably eerie feeling everywhere.
One of them, an old man in white, seemed like an endless black hole. Looking at him, one could lose oneself. The other slightly overweight old man, however, was enveloped by an endless flurry of sword lights. This terrifying aura of spiritual power was daunting to anyone who saw it.
This was not a deliberate release from the two. In fact, no one could mimic this aura easily. It was the type of aura that harmonizes with the Taoist Feeling with every breath, a sign of the subtle application of the Taoist laws.
