The reason the Azure Dragon Battle Group is called the "Ace" is partly because it boasts the highest resource allocation, the best equipment, the finest soldier quality, and the strongest combat power among all the military groups in Da Qian. Additionally, it is also because many of the backbone members of the battle group are from the imperial household.
Moreover, the main general and the two deputy generals of the battle group are all cultivators from the Purple Abode Realm.
Ordinarily, the main general is chosen from among the war-talented Commandery Princes of the Imperial Household. The current main general of the Third Regiment is from the imperial family, Ning Commandery Prince, Wu Yingjun.
