When Xuanyuan Qing'ao informed Xuanyuan Wuji that the collapse of Burial Soul Valley was related to an ancient battle between gods and demons and the Subduing Demon Hall, Xuanyuan Wuji was internally surprised but showed little emotion on his face, simply looking calmly at Xuanyuan Qing'ao before questioning him about Shangguan Linlang.
Previously, Shangguan Linlang had contacted Yu Siand in Xuanyuan Wuji's presence. From their conversation, it was evident they had also discovered anomalies in Burial Soul Valley, but before they could investigate deeper, the valley collapsed 'without warning', following in the footsteps of the Shangguan Residence. Xuanyuan Wuji himself did not believe all of this was mere coincidence.
Especially considering Han Ziye's appearance later, taking away the fake Shangguan Linlang who Xuanyuan Wuji believed to be an imposter. Moreover, the things Han Ziye said to Xuanyuan Wuji before leaving made him even more concerned.
