Upon discovering this problem, he furrowed his brows, momentarily unable to discern the specific reason; it was the first time he had experienced such a situation since obtaining the Skeleton King Blessing Contract.
"Is it because the distance is too far, exceeding the activation range of the Skeleton King's Blessing Contract, or is the specification of the Source Energy Points provided by the Crane Green Ascension Feast too high? The Skeleton King's Blessing Contract is, after all, only a Silver Card. Could it be that the Source Energy Points offered by the Crane Green Ascension Feast exceed the limit that a Silver Card can trigger?"
Filled with doubts in his heart, Gu Ran, however, didn't dwell too much on this issue. After all, there was no way to clarify the specific reason at the moment. He could only wait to explore it slowly in the future.
He withdrew his thoughts and quickly glanced at his own attribute panel once again.
