"Pathetic pesky ants," Tao Liu sneered to himself, having just dispatched the three sect guards stationed at the entrance to the sect's grounds.
He didn't immediately charge into the compound. It wasn't out of fear of detection, but rather, he had intended to be discreet in his actions that night. Being discovered too early would not be beneficial to his plans.
Once the guards were dealt with, a jet-black vial materialized in his hand. As soon as it appeared, Tao Liu wasted no time in uncorking the vial, promptly retreating as he did so.
The moment the cork was removed, a dark, fog-like substance started to flow out and spread into the air. This was the infamous Nightshade Mist.
The Nightshade Mist was an unusual dark cloud, not profoundly toxic in its essence, but deadly in its subtlety. It was odorless, making it incredibly difficult to detect, and prolonged inhalation could lead to unconsciousness or severe weakness.
