Wu River is a river that runs along the eastern edge of Yu County, where the Yu State Government Office is located, and it also serves as the border between Yu County and Lin Prefecture, dividing them apart.
Heading north along this river will lead to Bi Prefecture and Lang Prefecture, while heading south will take you to the most remote Yu County.

After Chen Mu quietly departed from the State Government Office, he traveled eastward, and with his current speed, he hadn't reached the midpoint of the day before arriving at the edge of Yu County, coming to the banks of the Wu River.
At this time, he stood with his hands behind his back on the riverbank, watching the rolling waters come from the end of his line of sight. The waters appeared murky, with a deep brown, raven color, created from a type of black sand carried from underground – a spectacle different from any other river he had seen before.
Black Sand.
