I bet it’s the other contestants in the treasure game. Would be troublesome if the fox sisters decide to follow them instead since all contestants are foxes… can’t wait to see how this turns out!! Thanks for chapter author!!
If it is a Fox that did this, and if this was in the real world, Tang Li Xue should pass them on to the Fox so that she can find the rest without blowing her cover. This is a game though, so I don't know what will happen. Thanks for the Chapter!
