"I can let you leave, but I want you to use the power of the Nether Palace to help us search for Daoist Mo Yun."
Wang Changsheng said.
Murong Bing took out a snow-white Immortal Transmission Mirror and tossed it to Wang Changsheng. "I can help, but I can't guarantee that we'll find Daoist Mo Yun. You must release Sister Mu. If anything happens to Sister Mu, I absolutely won't go easy on you."
"How will you help us find Daoist Mo Yun?"
Wang Changsheng asked.
"If I receive any news, I'll contact you through the Immortal Transmission Mirror."
Murong Bing said.
"How do we know you aren't lying to us? How about this: your friend comes with us first. Once we find Daoist Mo Yun, we'll release her immediately."
Wang Ruyan said.
"No. How do I know you won't kill her to silence her? I, Murong Bing, always keep my word. I swear a Heart Demon Oath that I'll do my utmost to help you find Daoist Mo Yun. Let Sister Mu leave first."
Murong Bing said, her attitude resolute.
"Fine! I'll trust you for now."
Wang Changsheng agreed. He had never expected Murong Bing to swear a Heart Demon Oath. Her credibility was still quite high.
He formed a hand seal, and the restraining force vanished.
"Sister Mu, return to Gold Firmament City first. Go!"
Murong Bing said.
Mu Yudie hesitated briefly before transforming into a streak of escaping light and flying toward the way they had come.
"Why are you looking for Daoist Mo Yun? Can you provide us with more information?"
Murong Bing asked.
"All I know is that he robbed the Azure Crane Merchant Alliance. I heard that he has a high-grade Aperture Opening Secret Method in his hands, and we're very interested in it.
