Chen Mobai approached and before he even got close, he felt a chilling sword intent that made his hairs stand on end.

At the top of the mountain, there seemed to be a spring. Tiny streams fell from above, one by one, into this stone gap. No matter how much water poured in, the stone gap was only seven-tenths full. The rest turned into cool mist that dispersed into the air.

"There is, but only one, on the door of the wooden house."

As Yan Qiongzhi spoke, she led Chen Mobai and Yan Bingxuan towards the Mirror House. She pulled out a key in the shape of a small sword. As the wooden door opened, a stern sword intent as majestic as a mountain range and as vast as the stars slowly dissipated.
