From the very beginning, letting the Cyan Simurgh Sect disciples inspect the storage bag was not within Lu Yan's considerations.
Other cultivators might at most carry some demonic magical artifacts or practice some demonic secret skills, and their storage bags might even contain a single refined corpse.
Strictly speaking, these people wouldn't pass the inspection, but their connection with the demonic path wasn't significant.
However, if the contents of Lu Yan's storage bag were exposed, it wouldn't just be a matter of being a demonic cultivator; he would appear as a rising star of the demonic path, a born demonic seed!
Lu Yan knew very well that once the contents of his storage bag were exposed, Xie Yun would certainly act against him.
Rather than taking a beating passively, it would be better to kill everyone present to seal the news before the inspection.
