417 Exploration and Encounter

Gu Lan held onto Zhou Bai as they progressed towards the depths of the heavenly palace.

Zhou Bai asked, "Why don't we just fly? Let's fly and see what the terrain is like here?"

Gu Lan shook his head and replied, "No... we can't fly. We'll be attacked."

After Gu Lan's explanation, Zhou Bai understood that in this strange space, if one were to fly higher than 3 meters, they would be attacked by an invisible force. Even with Gu Lan's seventh realm cultivation, they could barely withstand a few seconds and could only move within 3 meters above the ground.

Moreover, up to this point, Gu Lan still didn't know how to leave this place. After stepping into the lab's doorway, he appeared directly at the Northern Heavenly Gate, but he couldn't find any way to return.
