"Strange, why does it feel like the Tower of Azure Grievance is missing something?"
Sage Tathagata muttered to himself as he observed the Tower of Azure Grievance closely, trying to discern any clues.
At that moment, wisps of ghostly qi emanated from within the tower, quickly entwining around Sage Tathagata.
Sage Tathagata's eyes sparkled with intensity, yet he made no move, simply watching the Tower of Azure Grievance quietly, his gaze filled with anticipation.
Soon, the ghostly qi condensed into a tiny figure atop the tower, small as a grain of rice.
The figure's body was pitch black, with a dragon-like head and eight bat-like wings, its eyes red as rubies; he was squatting down, hugging his arms tightly around himself.
Staring at him, Sage Tathagata seemed contemplative.
"This being is born from malevolent energy—could it be a new spirit born from the resentment within the Tower of Azure Grievance?"
