The Purple River Lord had walked the path of poison his whole life.
He had refined countless toxins. He had bathed in poison miasma. He had even used the most concentrated water of the Purple Poison River as his elemental pool to advance into the Core Formation realm.
Because of that, he could feel the potency of the poison in his bones. He knew how terrifying the contents of that vial were even for a late-stage Lord like him.
This was not an ordinary poison. It was not something that could be made by refining regular Spirit herbs or demon beasts. It carried a depth that made his very soul feel uneasy. A depth that did not belong to common Spirit techniques.
His gaze locked onto the vial as if it were a priceless treasure. Aksai watched his reaction quietly.
"This is just a small sample," Aksai said calmly. "But to someone who understands poison… its value should be clear."
The Purple River Lord swallowed. His eyes never left the vial.
