Chen Fei glanced around. The Eighth-Order experts who had entered before him had all vanished by now; they had likely been scattered by the secret realm's array formation.
At the same time, an enormous force pressed down on Chen Fei's shoulders. This was a flight-sealing restriction. Chen Fei did not deliberately resist it, instead following the force of the restriction and landing on the ground.

Chen Fei looked at the dozens of towering mountains ahead, and his brows suddenly furrowed slightly.
Shi Ding An had said before that the cultivators within this secret realm had long since vanished completely, with no sign of living beings moving about. But from what he saw now, on some of the distant mountains, there were clearly surges of Heaven and Earth Essence Qi.
