Zhang Yanhang looked at the photo on his phone, manipulating the alchemy array to quickly sketch out the shape of a positioning marker on an A4 paper with black as the fill color. In just a few seconds, a positioning marker was created that was far clearer than any printout.
After the creation of the marker, Zhang Yanhang carefully observed the positioning marker before him, feeling that it didn't look like a proper marker at all. In his impression, these types of items were generally accompanied by things like pentagram arrays and magical runes, but the one before him looked more like a scribble drawn by a ghost.
Or rather, the positioning marker was covered in frenzied cursive that Zhang Yanhang didn't recognize as ancient texts, and they were interconnected with symbols that likely had special functions.
It didn't resemble a foreign magic array, nor did it look like the talismans used within the Empire—instead, it resembled a unique system of special runes.
