Ku Waowen was quickly working on a different thing than what she had come here for originally. Her plans had seemingly been flipped on its end, due to Lin Mu's appearance. And in addition to that, the revelation about the spies was far too much for her to bear alone.
Her clingers flitted across the formation array as she made one change after the other. There were some runes being added, and some removed, though she didn't change any layers of it.
Lin Mu observed this and guessed what she was doing.
'She's trying to draw spirit Qi from it?' Lin Mu furrowed his brows.
He was a bit confused as this was a complex thing to do as a formation array would hide sensitive functions like this deeper into its middle layers. This would prevent anyone from accessing it.
And what Ku Waowen was doing was certainly that. But it was stranger since she was not altering any layers at all and was only working on the surface.
