"Master, after demons transform into human form, they can freely choose their appearance. Most of them choose to look beautiful. The first appearance they take upon transforming will become their own permanent appearance afterward. Of course, they can use spells to alter their looks, but such changes are merely illusions. They are easily seen through."
Easily seen through?
He meant easily seen through by himself, perhaps.
How could ordinary people possibly detect it so easily?
"What else?"
"Demons with weaker strength, in the beginning, will retain some of their original traits, such as ears or noses and the like. But as their strength increases, those features will gradually diminish. If it is a thousand-year great demon of that level, then they will become no different from ordinary humans. However, there is one thing that no demon can ever change."
Bai He knew this. "Demonic aura."
"Master is very clever."
