Yan Nanfei's expression suddenly changed. He had obviously heard the legend of the Dark Seal of Life and Death. Once this thing was planted in his body, he would look at Mu Yun's face in the future. If Mu Yun was harmed in any way, he would suffer as well.

"You think about it carefully."

Mu Yun's expression was calm and he did not urge Yan Nanfei.

Yan Nanfei gritted his teeth and said, "Okay, I promise you."

"very good."

Mu Yun nodded and immediately released the dark seal of life and death.

Yan Nanfei did not resist and accepted it directly.

Mu Yun breathed a sigh of relief. This way, he was no longer afraid of Yan Nanfei causing trouble.

"Tell me, how can I rescue you? If I guess correctly, this mountain is the legendary Ren Yuan Bi, right?"

Mu Yun looked at the bare mountain cliff. If it were an ordinary mountain, he could destroy it directly and rescue Yan Nanfei, but this was a human yuan pen, so it was obviously impossible to destroy it.

"I didn't expect you to recognize Ren Yuan Bi. Yes, this mountain is Ren Yuan Bi. Back then, my traitor used Ren Yuan Bi to suppress me." Yan Nanfei gritted his teeth thinking about the past.

"He is so willing to use the Ren Yuan pen to suppress you. With this magic weapon, he might as well keep it for himself."

"He can't use it. Ren Yuan Bi has given birth to wisdom and weapon spirits. The one who ranks first on the master list is Ren Yuan Bi's weapon spirit, King Ao Ren."

"King Ao Ren is the weapon spirit of Ren Yuan Bi?"

Mu Yun was speechless for a while. He had also heard about King Ao Ruo, who ranked first on the master list. It was said that this person's identity was very mysterious and his cultivation was extremely powerful. No one knew his background.

But Yan Nanfei actually said that King Ao Ren was the weapon spirit of Ren Yuan Bi.

"Back then, my traitor offered a huge price and entrusted King Ao Ren to suppress me. The price was so tempting and huge that King Ao Ren couldn't help but cooperate with him and suppress me directly."

Yan Nanfei felt sad and angry again when he talked about the past.

"What price did he offer?"
