Attack from Western Self-Cultivation Realm

Qingfeng's eyes filled with surprise when he heard White-Crane Fairy.

"White-Crane Fairy, how do you know that this white wall doesn't belong to the Eastern self-cultivation forces?" Qingfeng frowned as he asked. 

White-Crane Fairy smiled and explained, "Qingfeng, let me tell you, I train in the Immortal Crane Technique and the Eastern Astronomical Method, so I can feel the foreign energy on this white wall."

The Fate Elder beside them also said, "That's right, I can sense the great presence from this white wall as well. The energy it releases definitely doesn't originate from Eastern self-cultivation techniques, it's closer to the Western self-cultivation techniques."

Qingfeng frowned and came up with a crazy thought. Could the Western self-cultivators have arrived here, and built this white wall to trap all the Eastern self-cultivators inside?
