"Ah, Mu Girl—"
Mu Ying was practicing Water Walking on Moon Lake when she heard someone calling from the shore.
Turning her head, it was Professor Su.
Eagerly calling her must mean there was something important? Mu Ying responded and walked toward the shore.
"Professor Su, what brings you here?"
Professor Su waved his hand and pulled out a parchment from his pocket, "I heard you were practicing a Spell that allows free movement above and below water, so I drew this from memory. It might not be very accurate."
Mu Ying took it and saw that it was a map, "This is..."
"This is a map of the mineral distribution around Coastal City, mainly an iron mine, a coal mine, and a sandy mine containing gold, silver, and copper. There are also others... I hope this can help the territory," Professor Su explained the various mining sites to her and taught her how to identify the ores.
