Indeed, the seals Li Yun had placed around the Qingqiu Mountain were strong enough to contain her from leaving. However, what the great shaman didn't anticipate was the possibility of her possessing yet another host to escape the mountain.
Also, because she was also bound to a contract with Zhao Yichen, the seals failed to recognize her as an escaping entity and alert the Li family about the matter.
"Perhaps they are worried that the demon would come after you since you are part of their family. Classmate Li, I would be wary if I were you. Demons like a nine-tailed fox are vengeful creatures. You should have known, by now, just how many humans have lost their lives because of that fox demon."
Li Fei'er hummed and looked at Shen Minyao with amusement.
"So even Classmate Shen has already heard about the nine-tailed fox, huh?"
Shen Minyao scoffed and looked away. How could she not know when she was that demon Li Fei'er was looking for?
