Oathkeeper tried his best to suppress the shock in his mind and keep his mind frequency stable, so Han Xiao would not find out he panicked.
He observed Han Xiao's expression and mind frequency, but he could not see any mockery from him, only curiosity.
Did Black Star ask about the Sanctum because he knew the Holy Accord's plans, or did he hear about this name somewhere else? There were not that many people who knew about the Sanctum throughout the entire universe.
Oathkeeper's emotions were like a tiny boat in the raging sea. He maintained his cool as much as possible. He acted casual and asked, "Where did you hear about the Sanctum?"
"Someone told me." Han Xiao casually lied—no way he was going to tell the truth.
"Who?" Oathkeeper continued asking. "There are very, very few people in the entire universe that know about the existence of the Sanctum. Even advanced civilizations might not."
