The underground passage was only about ten meters long. Quickly, everyone reached the end and entered a square cellar.
It was hollow inside, with only a stone door standing in the center. The door was carved with lifelike flowers, birds, fishes, and insects, and showed no signs of spiritual power fluctuations, appearing like a simple painting.
On both sides of the stone door hung two oil lamps emitting a green glow, lighting up the entire cellar.
As Xu Mu entered, an inexplicable chill sprouted in his heart.
The woman stood in front of the stone door, squeezed a spell, and then a terrifying pressure erupted from within her.
Hiss!
Everyone felt their bodies suddenly sink, as if a giant rock of thousands of pounds had suddenly landed on their shoulders. Their muscles tensed and they quickly mobilized their spiritual power for defense.
This pressure was much stronger than the Nascent Soul Stage, and might have reached the Divinity Transformation Stage.
