"Ding!"
"Merit Points -500, Wulei Rules +1."
A string of data popped up on the system attribute panel.
"Does Wulei Rules consume so many merit points?"
Xu Yang was taken aback.
He had previously used merit points to upgrade the "Water Manipulation Skill", consuming 50 points of merit to gain "Water Manipulation Skill +1".
But now, "Wulei Rules +1" consumed ten times more merit points!
Before he had time to complain, Xu Yang's face changed.
He felt his internal organs as if they were struck by electricity, a sharp pain instantly hit him, making him almost faint, faint arcs of electricity flickered on his body.
At this moment, Xu Yang seemed to have the ability to "look inward".
He "saw" those faint arcs of electricity refining his five viscera, causing them to undergo a unique change.
Xu Yang had an enlightening insight in his heart.
