Zhao Yu glanced at the many treasures in the hands of Fairy Cai Ling and, after pondering for a short while, took out the Spirit Stones and various Superior Grade Spirit Pills from his storage bag to purchase the numerous Second-Order Fierce Ghost Relics she had.

With a wave of her hand, Fairy Cai Ling collected all the remaining treasures and did not inquire why Zhao Yu chose those Fierce Ghost Relics.
