Every time the ring called him into the space, there was a reason for it. Either it was a new skill that Lin Mu received or a technique. But now it was nothing like that. This left him confused.
This was of course until, he looked at the runes that faintly glowed on the altar. These runes would change every so often and looked to be random at first. But the more Lin Mu looked at them, the more he found them to be understandable.
"Wait a minute… aren't these… similar to the ones used in the formation nexus?" Lin Mu recognized.
He placed his hand on the altar once again and focused on the runes that he had recognized. They appeared on the altar once again and this time they didn't disappear, allowing Lin Mu to understand them better.
He combined the information and knowledge he had learned earlier with the current runes in front of him before coming up with something he had never expected to be able to do this.
