Hunting packs of wolves

Lumen was worried that he would have to go back through all of the previous trials once again if he wanted to go back to the caves. However fortunately for him the system seemed to actually be benevolent for once, as a prompt appeared in front of him as soon as he stashed the spear in his inventory.

[Hidden treasure cave will disappear in 60 seconds, teleportation has begun.]

Lumen didn't even have time to even properly read the message as the teleportation was instant. One moment he was still in that small room with the now empty bookshelves being the only furniture, then he blinked and the next moment he was back outside of the glowing pile of moss where he first entered the hidden treasure cave.

However this time when he attempted to look behind the moss at the entrance, the opening in the cave wall was gone and replaced by the same dull stone as the rest of the cave.
