Calling Forth The Alliance's Formation Masters

Finding out the mountains were actually real was shocking to Lin Mu.

"How can they be real if they are supposed to be an illusion? They don't show any signs of being that either?" Lin Mu was muddled.

"In a way, they are and in a way they are not. This is certainly a very high leveled illusory array since it can form actual physical objects. It was definitely not set by anyone below the immortal realm." Xukong said, much to Lin Mu's surprise.

"You mean to say… the northern tribes had someone at the immortal realm come to the Xiaofan world and set it up?" Lin Mu was a bit anxious hearing this.

"It is possible, but what is also possible is that a single use immortal tool might have even been used to set this up. Something like a talisman. If they got Immortal Talismans, then even Dao Treading realm experts would be able to set it up. Though that is still a far shot." Xukong explained.
