"Why are you here... Tenebris... you... betrayed me..." Supreme Left struggled to finish his sentence as a second pole pierced through his lung. His vitality was absorbed by the poles, turning the youth's hair white while his skin wrinkled and became leathery.

When his vitality was nearly gone, his body slumped to the floor, his eyes still wide with shock. The poles were retracted from his heart and lung and were retracted into a pair of sleeves that had just condensed.

None of Supreme Left's Artifacts or life-saving measures activated, which spoke volumes of how much time the shadowy figure spent preparing for this moment. The other Cultivators were scared stiff by this sudden development, unsure if the newcomer was an ally of the boy or not.

As Supreme Left took his last breath, a wisp of light exited his mouth, which was immediately crushed by the shadowy figure known as Tenebris. Any hope of revival for Supreme Left was destroyed in that moment.
