"Ancestral Citadel?"
As these two words began to spread within the building, the expressions of the Darkness Master's group became focused. Then, they turned their attention towards Ying Huanhuan, before they hesitated for a moment and asked, "Are you sure about this?"
Ying Huanhuan nodded.
"What is the Ancestral Citadel?" When Lin Dong saw their expressions, he felt a little uneasy in his heart as he quickly asked.
Ying Huanhuan lifted her pretty face. Then, she used her pretty icy blue eyes to look at Lin Dong before she smilingly said, "It is a citadel left behind by teacher. Your Mental Energy cultivation is currently at the Supreme Symbol Master level and you have yet to form a Divine Palace, am I right?"
