章 651: The Mysterious Castle

"What a strange Formation Art… Did they collect all the Mystic Formation Nodes to produce this?" Marcus III remarked after he realized that his senses could pass through the illusion, but his physical body could not.

It means that if they didn't deliberately go through this path, they would've missed this place entirely… It was such an amazing Formation Art!

As Marcus III touched the strange barrier, he started analyzing its structure, hoping to find its weakness.

Although he was already touching it, he could only feel a faint trace of a formation that was camouflaged among the trees, rocks, and the mountain itself. It was a complex and intricate formation that used several Mystic Arts to create an illusion.

It was a formation that could only be made by a master of Formation Arts.
