The next moment, the cave mansion closed, and an array formation light screen appeared before them.
"What is this?"
All the Holy Mountain disciples looked surprised. They had lived in their cave mansion for so long, yet they had never seen this thing before.
At this moment, the voice of the First Holy Master echoed in their minds once again.
"Holy Mountain disciples, hear my command. Infuse your spiritual power and mana into the array to maintain the big array."
When all the Holy Mountain disciples complied, an incredibly powerful array fluctuation emanated from the Holy Mountain.
The strength of that fluctuation was so potent that even the four demons in the sky couldn't help but change their expressions.
Little Yan also turned back somewhat surprised. She too did not know that the Holy Mountain had such a hidden trump card.
