The demonic thing laughed strangely and said,"you're really wasting my time. I've taught you for so long, but you can't even see through a concealment array!" That hou fellow is right beside the concealment formation. If you go over, you'll probably be ambushed by them. I can only help you up to this point, you can do the rest by yourself!"
"A concealment array?!" Lin Yi was a little surprised. His array skills were still weak, and he could barely set up a level two stealth array, but he could still see through normal level three and even level four arrays.
His spirit sense couldn't find anything unusual, which meant that this formation was powerful and high-level. Lin Yi immediately thought of the level eight formation disk he got from the sixth room.
Sky Class island's classification of formations was completely different from elixir making. Anyone who could set up a formation from level one to three was a Gold Class formation master, and Lin Yi was at the gold Class.
