"Gemstone Duchy?"
Mu Yuan's gaze grew sharp.
The gap between duchies was immense.
Duchies within major power factions were the true grand duchies.
Just like their Tai Xuan Alliance.
Within the alliance, only a handful of powers dared to call themselves duchies, like the formidable Lord Beiting in the northern border of the Tai Xuan Alliance. Lord Beiting's combat power might not necessarily surpass that of the renowned powerhouses like the Lord of Han Yue City or Sword Lord Liushi, but in terms of the overall scale and the number of strong warriors, Beiting Duchy could leave Han Yue City thirty streets behind.
A duchy was just that formidable.
