The only way to return back to the surface was to wait for Elder Lai Chang to come to him and take him out of here.
However, even before that, Ye Tian Yun had a very important thing to care about.
He had to get everything in the hall back to normal.
When Ye Tian Yun first entered this hall, he had found himself in a forest.
However, it turned out to be an illusion, and a dull room was revealed.
After that, he had practiced his sword moves on the wall and ended up creating cracks on the wall, almost breaking it.
After that, he attacked a single wall to get to the adjacent hall, where he found the spirit vein.
Luckily for him, everything on the last wall was auto repaired by the wall itself due to the array.
He only needed to worry about the marks left by his attacks on the nearby places, the adjacent walls, and the floor.
