Gu Xijiu was surprised that the Firmament Stone could take photos. She looked at the picture and finally saw the locator. It looked like a Setaria viridis. There were some light red fonts around it which she had never seen before. It looked like Sanskrit, but it was not as she could not recognize any of it.

As she had already rubbed off half of it, a lot of the fonts were already gone. She tried her best to enlarge the photo but still could not see the strokes. She sighed and regretted that she did not take the picture first before she rubbed it off.
