Taking off the disguise masks, the four plain people who seemed to have died in the mist just a moment ago turned back into Michelle, Ivona, Anastasia, and Kieran.
"I never knew Nyxaroth could do that..." Ivona mumbled. "And were the ashes just to fool them?" she asked, feeling a bigger conspiracy. In the end, Michelle did say that she would take care of poisoning everyone in the mansion, but they didn't see her do anything like that yet.
Michelle retracted the black mist she created using her dark element and smiled a bit. "The 'ashes' were a poisonous substance, solidified and ground into dust. Once anyone breathes the dust in, it will react to the wetness inside their nose and airways and turn into poisonous liquid, which will seep into their organs and spirit veins, at first just ruining their cultivation slowly, and when they become completely powerless, then they will die."
