Under the suggestion of Tian Zhang True Monarch, Zhang Yu activated the mana within his body, infusing it into the Divinity Transformation artifact in his hand.
He only felt a slight tremor in the rhombus-shaped crystal he held, and after his mana surged through it, it quickly returned the mana back to Zhang Yu's body.
When Zhang Yu attempted to infuse his mana once more, the artifact directly rejected it, as if it had sealed itself off, preventing his mana from entering.
Tian Zhang True Monarch, witnessing this scene, narrowed his eyes slightly, thinking to himself, "Again the mana surges back. Indeed, Qiongjiang Divine Monarch's Divinity Transformation artifact does not simply extract mana from Zhang Yu unilaterally."
"But then why does it refuse further mana infusion... what could be the reason?"
"Is it some kind of restriction?"
