The purple mist within the cauldron was just like a snake made of flames, constantly writhing around within the cauldron.
"It's really the Purple Flame Spirit Qi. The Purple Flame Spirit Qi is colorless under normal temperature and will only show its many shades of purple when it's under high temperatures. This Purple Flame Spirit Qi must have been placed there by the black shadow earlier." Ling'er laughed as her eyes lit up too.
"The black shadow from earlier?"
"Yes. If it hadn't been for my timely reminder, the moment you used this cauldron to cultivate the Appearance Pill, the Purple Flame Spirit Qi would have also been cultivated into the Appearance Pill. If you had fed the pill to your Martial Mother, she would definitely have been burnt to death by the Purple Flame Spirit Qi, and there would be no traces left after her death. The person who wants to frame you is really very vicious," said Ling'er with a frown.
