That aura was coming from the first floor of the pyramid.
It was an aura that made people feel uncomfortable. When she sensed this aura, Lady Onion felt as if she had been thrown into a puddle of filthy mud.
The aura disappeared as quickly as it came, just like a gust of wind. After a short moment, it was gone already.
Lady Onion furrowed her brows, and asked, "What's the matter with this aura?" She found this aura very familiar, but she couldn't recall where she had sensed it before.
That female monster next to Lady Onion also had an uneasy expression on her face.
"I have no idea... it's my first time sensing this foul aura," the female monster replied. Although she had lived in the pyramid of this branch for the past few days, she had never sensed this aura.
Lady Onion suddenly thought of something, and said, "Foul and filthy aura...? There is no mistaking, this is the evil energy of the Netherworld Realm!"
