Chapter 630: Ancestor Soul

Lin Yun made a trip around the palace and easily found an array.

This array was at the front of the flight of steps.

Lin Yun took out ink, a quill, and a dozen pieces of paper and started calculating rapidly, writing down many illegible words and numbers. After no less than ten minutes, Lin Yun put away the paper and took out a crystal pen to start cracking the array.

A dozen minutes later, he touched a rune on the first step.

"Rumble…"

A mechanical sound echoed as the floor in front of the flight of steps sank.

While it shook, a small platform rose up from the cavity. The small platform looked as if many arrays had been stacked together, as a great number of patterns were converging towards the notch in the middle.

And in that notch was a book-sized crimson crystal. The crystal had several dozen faces and a flame of similar color was slowly swaying inside.
