Just as Alex was staring in a daze, the Devouring Yin Ghost suddenly opened its bloody maw and let out a fierce roar at him, seemingly as a show of force.
Only then did he snap back to his senses. He directly waved his hand, tossing the two Ghost Servant Contracts into mid-air.
Compared to the Devouring Yin Ghost's massive body, the Ghost Servant Contracts were as tiny as grains of sand. However, the instant they flew to their highest point, the contracts suddenly transformed into black light and fused into the Devouring Yin Ghost's forehead.
After absorbing the Ghost Servant Contracts, the originally irritable Devouring Yin Ghost instantly settled down as if hit with a tranquilizer.
It obediently knelt on one knee and lowered its forehead toward Alex, expressing its submission.
"Very good." Alex nodded with a satisfied smile, secretly pondering that this Ghost Servant Contract was indeed miraculous. It was not in vain to expend so much spiritual energy just to refine one.
