The headquarters of the Ai Family is located in Wanhua City, within the Canglan Domain of Xuanwu State.
Wanhua City is nestled amongst mountains, surrounded on all four sides with the middle being the highest. At a glance, one can see all the movements in the surroundings. Most remarkably, formidable natural barriers span on all sides, making it easy to defend and difficult to attack. The Ai Family's existence for over five hundred years is not unrelated to this geographical advantage.
Besides, the mountains on all four sides are blossoming with various kinds of flowers all year round, beautifully painted in purples and reds, creating an illusion of a spectacular flower sea. Whenever a breeze blew by, it would stir up the sea of flowers, and people in the city could smell the refreshing floral fragrance, making it hard for them to leave.
It is said that the initial feud between the Xiahou Clan and the Ai Family started over the desire to seize this precious land.
