"What's he doing here?" Duan Ling Tian frowned when he heard Li An and stopped comprehending the Divine Ability, the Black Turtle's Barrier.
Currently, he had already spent six months comprehending the Black Turtle's Barrier in the fourth level of the Seven Treasures Exquisite Pagoda.

Perhaps, his progress would satisfy many of the Black Turtle Sanctum's disciples, but it was not good enough for him.
Previously, when he comprehended the two high-grade Divine Abilities, the Elementary Devouring Tactic and Otherworldly Celestial, it did not take long for him to comprehend and master them. However, he had spent six months comprehending the Black Turtle's Barrier, but he did not make much progress. It was only natural that he felt dissatisfied and unhappy.
