Chapter 586: Mysterious Rock

As the long-faced man was thinking, he suddenly heard a sound coming from a shop.

"Dear Sir, this mysterious rock was dug up especially by us from inside a deep cave. The cave was extremely dangerous and abnormal. It is unknown how many years this mysterious rock has been buried underground. It cannot be ordinary! No matter what item it is refined into, or what research it is used for, it will be extremely useful, but you are only giving me twenty low-ranked relics for it? Isn't that too little?"

This voice sounded extremely familiar to Yi Yun. As he had a good memory, a simple recall identified the voice to belong to the man who was in his twenties, out of the trio who he met when he entered Heaven Martial City.

Yi Yun's raised his eyebrows as he looked inside.

He saw three figures standing at a counter inside a bright hall. A fist-sized dark golden rock was placed on the counter. And across the counter sat a round shopkeeper in his forties.
