Watching this scene, Zhu Fei suddenly reached out and grasped the air.
Only the "whoosh" sound was heard continuously, as nearly nine crystal stones resembling that white jade flew out from the ground, and were directly grasped in Zhu Fei's palm.
Looking down at the white jade stones in his hand, Zhu Fei finally revealed a smile on his face at this moment.
"So these white jade stones are called Immortal Crystals, no wonder this complex and intricate array can always be maintained with these things."
After three years of deductions and research, Zhu Fei had already obtained much forbidden knowledge related to the ancient era from these two arrays in front of him.
Originally, Zhu Fei shouldn't have known these things, but during his deduction of the two arrays, he inadvertently touched upon a message image within the sealing array.
It was through this message image that Zhu Fei learned certain things he wasn't supposed to know yet.
