After the countdown ended, Yan Yu led the team into the Mysterious Realm.
Within the realm of Fengdu, the visibility had dropped even further compared to the outside—the outside was a bit like black smoke and haze blocking out the sky, but inside it was simply deep into the night. Only the moonlight above could faintly illuminate the outlines of the nearby mountain peaks.
At this moment, the team seemed to be in a mountain ravine with unclimbable cliffs on both sides, almost perpendicular to the ground at 90 degrees.
Of course, they could climb up using the Cloud Ascension Technique, but most likely they would encounter an air wall... Although the Mysterious Realm was created for various purposes, it certainly did not include letting outsiders play sandbox games. A path that's clearly not meant to be taken, forcing your way through would not reveal any map easter eggs.
