"A copper coin" said the stall owner.

Tang Yan nodded slightly, then took out a copper coin. Of course, she had such a copper coin, which was given by the family.

Tang Yan took the copper coins and exchanged them with the stall owner, and then got the stone bead. Now the stone bead belongs to her.

Tang Yan thought that this stone bead might be related to magic, so she got the stone bead. The first step was to try to detect it with her mental power, and then Tang Yan saw something surprised.

She found that the surface of the stone beads was not smooth, but was composed of some strange dots connected. These dots were extremely small and could not be seen without observation with mental power. There were hundreds of thousands of interconnected places on the entire surface of the stone beads.

"This pearl is extraordinary!" This is what Tang Yan thinks now.

She tried to observe one of the dots with her mental power. Something even more terrifying happened. She found that the already tiny dots were like miniature cities, with countless extremely complex magic patterns inside them.

When the magic patterns on the entire bead are combined, they may be more than a hundred miles in length.

Tang Yan felt extremely shocked. How to use this bead

Tang Yan wanted to use her mental power to observe the structure of the stone bead, but she was immediately bounced out by a powerful force and could not be observed at all.
