Alex went around the place, copying the runes down so he could learn about it later. If not him, he could give it to his mother, so she could learn from it.
"My spiritual sense is struggling in this place," Alex said with a bit of a struggling look on his face. "Is that the room? Or just the Yin?"
"Could be the room," Godslayer said. "But a heavy concentration of Yin or Yang Qi is known to make it impossible for you to properly use your own Qi and senses."
Alex nodded. He was reminded of the Forbidden Fields, where the Nine Yang Divine Tree had taken root, and thus one could not use their cultivation base there at all. It was so difficult to use his spiritual sense there too.
The same was happening here as well but on a much weaker scale. The Yin Qi was strong, but not strong enough for it to stop him from using his spiritual sense and Qi entirely.
