Lin Chuan.
Since Gu Wen began collecting medicinal fruits, this county located in the mountains had constantly been under his watch. Nearly half of Bianjing's medicinal materials came from Lin Chuan County, and now it had fallen?
Gu Wen continued reading the letter, which was not sent from Lin Chuan but from the South Water County Governor.
The gist of it was that merchant ships sailed from Lin Chuan along water routes through South Water and Luo River Counties and reported the fall of Lin Chuan County to the officials, who then sent the information onwards to the governor's mansion. The Prefectural Governor then wrote a feather dispatch and sent someone to deliver it to Bianjing.
What followed was a long section where the South Water County Governor boasted about his own accomplishments, seeing it as an opportunity to curry favor with higher-ups.
