The Ice Demon, to ordinary people, is an extremely terrifying creature because this creature harbors a horrifyingly cold energy within its body.

She had been cultivating in this Ice Dome Prison for seven days. During this time, she constantly endured the chilling winds and absorbed more than a dozen Ice Demons.
