Lin Mu got to work on the formation array while the Saintess observed it all.
She could see everything that Lin Mu was doing, from the smallest of rune additions he made, all the way to the unraveling of different layers. Nothing escaped her eyes and the more she saw the more satisfied she was.
It took Lin Mu over three hours to completely unravel the formation array, but it felt like mere minutes to him. He was so engrossed in it that, he couldn't even tell when the time was passing.
To him, working on a formation array was like working on a puzzle.
Once one got into the flow, they would forget about everything else and fully focus on it. The Saintess had noticed this and knew that Lin Mu had an innate talent for formations, as not everyone could replicate this kind of natural focus.

The formation array broke down and opened up the passage for Lin Mu to enter.
"And, it's done!" Lin Mu said, finishing his work.
