A Puzzle Of Immortal Senses

In the middle of the hall, a circular structure was erected. 

It had an elaborate design with ten horizontal protrusions rising from it. These protrusions were at an equidistant position from each other and were at the exact height for a person to touch it comfortably. 

They were sharped like spheres, and even had the imprint of hands on them, hinting that they needed to be touched. 

There were several runes carved onto the sphere, as well as the rest of the structure, showing that this was a large formation array of some kind. Lin Mu couldn't recognize it from a single glance, but seeing the ten spheres, guessed that it needed all ten of them to activate it.

"Is that the final obstacle?" Ziran asked, seeing the structure and its design.

"Yes." Crown Prince Feng Shun replied. "We've tested it a bit, but we're unable to do anything." He revealed.
