At first, there was no change in the surroundings. The starry sky-like ceiling remained, and the walls on both sides glowed with a soft white light. The sea of fog beneath their feet stayed the same. However, as the group moved deeper inside, the starry sky above remained unchanged, but the light on the walls gradually shifted from white to a faint blue, pure as the sea. If you closed your eyes, you could almost hear the sound of the sea. The fog beneath their feet remained unchanged.
This change was something Old Tian and his group had never seen before. Old Tian gestured for the group to be cautious and then whispered to Yi Tian, "Be careful, we've never encountered such a change before."
