Players were using the Virtue System, which was essentially a ritual for invoking Gods, albeit greatly simplified.
In ancient times, rituals often included various offerings, ritual vessels, and music to properly invite the Gods to assist.
Moreover, the offerings before the rituals were merely the "travel expenses," and whether a wish could be realized or not was an entirely different matter. After a wish was fulfilled, a promise had to be returned, or they would destroy you.
When Black Tech mentioned that their concert also included these elements, he was a bit worried whether it would work.
But judging from the current situation, things couldn't be better.
Recalling past stories, he looked at Fang Cheng beside him and asked with slight pride, "Great Heavenly Lord, how do you think I did with this invocation ritual?"
"Pretty good, better than me," Fang Cheng sincerely replied.
