Hidden Knife

Yun Ai checked Xiao Ya's pocket and saw a small token with the "Moonlight" word. Immediately, she understood something and quickly brought Xiao Ya to the top floor.

At this moment, Yun Lintian focused on inscribing ancient runes on the formation stones. When he heard a knocking sound, he frowned slightly and said. "Come in."

Yun Ai stepped into the room with Xiao Ya in her arms and said. "I'm sorry to disturb you, Master. Please take a look at this."

Yun Lintian looked at Xiao Ya in doubt and then shifted his gaze onto the token. His brows raised slightly, and he picked the token up. 

As he injected his profound energy into it, Jiang Yingyue's voice immediately resounded.
