Songfeng, Jingyang, and Shengwu, the three cities, are all located in the north of the Taixuan Mountain Range. If the three cities were connected in a line, they would resemble a crescent moon, partially encircling the Taixuan Mountain Range.
Before departing, Zhao Fuyi estimated the time needed to connect the City Defense Great Array of the three cities. If everything went smoothly, it would take half a month. In case of any setbacks, she assured Jiang Yuebai that she would definitely complete it within a month.
Once the great array of the three cities is successfully connected, leaving Zhao Fuyi alone to oversee the three cities would be sufficient. The City Lords of the three cities could then lead everyone to launch an all-out assault on the Taixuan Mountain Range.
This meant that Jiang Yuebai had to guard the Taixuan Mountain Range for a month, constantly monitoring the movements of the Demon Clan and relaying information to the three cities.
