Or What?

After Grey acquired the Great Void technique, he unexpectedly didn't find any other thing. Other than clearing the path of all monsters he saw on the way, he didn't do anything else. He soon got to the end of the path, and it was blocked!

He couldn't help but ask Void if his senses were correct. Void first complained about being doubted before telling him he could still sense it, and the energy was coming from the other side of the wall that blocked the path.

Grey further studied the wall and found out there was a seal on it. It seems he would have to wait for it to open automatically. Having nothing to do, he couldn't help but think of his friends.

.......

On the other side, Klaus and the other two had just arrived at the end of the ancient path they took. When they got there, there were also other geniuses looking around, trying to find the entrance to the place the final treasure was located, but to no avail.
