First Institute.
Gu An walked in and found that the Eight Sounds Formation was as profound and mysterious as always.
Currently, those who entered were unable to escape the suppression of the Eight Sounds Formation.
Gu An felt that even if he got deeply trapped within, it would be difficult to escape.
This showed that Dongfang Changli, the weakest in the Divine Monarch Hall, far exceeded the Blood Demon Divine Monarch and the Nine Heavens Divine Monarch.
At the bottom was the Blood Demon Divine Monarch, for he was not even as good as the Nine Heavens Divine Monarch.
After entering, Gu An tried to use his own cultivation to strengthen the array, but found it impossible.
First, he didn't understand enough, and second, his own strength was not up to par.
"I wonder if Dongfang Changli could strengthen it further," he thought as he walked into the courtyard.
Upon entering, he saw Zeng Lan walking out.
She was quite surprised to see him as well.
