"Oh?"
Qin Feng was also a bit puzzled and said, "From the way you talk, are you from the Upper World?"
"Indeed, I am a disciple under the 'Mu King' of Tianmu Mountain in the Upper World!" The white-haired old man spoke proudly, especially when he mentioned the name "Mu King", a sense of pride naturally emerged.
He originally thought that Qin Feng would be taken aback upon hearing the name "Mu King", but Qin Feng had no reaction at all.
There was nothing he could do.
No matter how powerful "Mu King" was, Qin Feng didn't know him.
He took out a key, showed it to the white-haired old man, and asked, "Do you know what this is?"
"Hmph, just a key..."
The white-haired old man had just finished speaking when he suddenly remembered something. His eyes widened as he looked at the key, and he said in shock, "It, it's actually with you??!"
"You do recognize it. So what's its use?"
Qin Feng asked again.
This key was given to Qin Feng by Li Tianzi, the mother of Xiao Wu.
