Not my concern

Outside the Midnight Inn, Lex could not even read the writing on the envelope, though as he pulled it out now he saw that it was nothing too mystical. The front on the envelope simply read: Innkeeper.

Admittedly, the name was written in a deep crimson ink, in the most beautiful calligraphy Lex had ever seen. It was also filled with enough spiritual energy to turn a barren planet such as earth into a 5 star planet, and gave off a pleasant aroma he could smell with his very soul.

Furthermore, even with his Host Attire protecting him, Lex could feel the burden on him increasing so he quickly looked away, and spent a few minutes to recover.

It seemed like the effect of the Inn to negate harmful auras was not entirely effective on Dao Lords. It was predictable.
