At True Lord Tianzhang's suggestion, Zhang Yu activated the magical power within his body and poured it into the Spirit Transformation Yin Artifact in his hand.
He felt the diamond-shaped crystal in his hand tremble slightly. After swallowing and spitting out his magical power for a moment, it quickly surged the magical power Zhang Yu had injected back into him, returning it to his body.
And when Zhang Yu tried to inject magical power into it again, the Yin Artifact directly refused, as if it had sealed itself off, leaving his magical power unable to enter.
Watching this scene, True Lord Tianzhang's gaze narrowed slightly. Magical power surging back again. As expected, Nectar Divine Lord's Spirit Transformation Yin Artifact won't simply drain Zhang Yu one-sidedly!
But why did it refuse further magical power injection afterward...?
Some kind of restriction?
After thinking for a moment, True Lord Tianzhang looked at Zhang Yu and asked, "How was it? Did you sense anything unusual? Has your Martial Arts improved at all?"
Upon hearing True Lord Tianzhang's question, Zhang Yu immediately fell into hesitation!
Should he take this chance to raise the Martial Arts level others perceived him to have by a few more grades?
But if I keep raising it, this project will attract even more attention. What if I get exposed later?
Thinking of how even the Deity Transformation principal of Ten Thousand Laws University was watching this Yin Artifact project, Zhang Yu became even more hesitant!
Seeing Zhang Yu's expression, True Lord Tianzhang merely assumed he had not sensed any changes yet and comforted him, "It's fine. There was very little reaction this time, so perhaps the effect wasn't obvious!"
"Get a physical examination later. After you return, observe yourself carefully and feel whether there are any changes in your body!"
