"Just pass through that door to get straight into the final challenge."
The voice guided Ken, and as soon as the latter passed through the door, he could sense the vague activity of the formations in the room with his Runic Qi.
He was learning the mechanisms of the formations ever since he entered. Although they were seventh-rank or even eighth-rank, his understanding of the specific formations increased as they were the same in all buildings, and he did his best to spread his Runic Qi whenever he could to probe them.
As Ken expected, his location was shifted, and he was taken to another room than the one naturally attached to the door he passed through.
"Welcome to the final challenge of the Library of Eternal Wisdom-"
"Did the elder order you to mention its name all the time?"
"Yes."
There was an awkward silence for a moment before Ken broke it.
"It's a good name, he has a good taste."
