Open the Mystery Box. I'm a Professional

Lin Xuan took a few steps closer and squeezed into the crowd. He finally saw what was on the stall.

They were spherical objects wrapped in earthen yellow rocks. They were all about the same size and were about the size of a human head.

At this moment, there were more than 300 stalls.

There were also many rocks that had been knocked open beside him.

The stall owner was a dark-skinned middle-aged man in his forties. He looked very honest, but every time he shouted, his eyes would reveal a hint of shrewdness.

"Brother, what are these?" Lin Xuan casually asked the martial artist beside him.

"A stone cocoon."

Lin Xuan wanted to ask more questions, but the other party was too lazy to answer.

Lin Xuan used a High-Level Observer skill on the stall owner.
