The Northern Domain Mo Family, when viewed across the entire Profound Immortal Realm, is an undisputed overlord.
Moreover, compared to the disorganized state of the major forces in the Longevity World, where only the Immortal Countries are slightly larger, the Profound Immortal Realm has maintained nearly complete rule for ten thousand years.
Such rule naturally leads to highly centralized power and resources.
This can be seen from the fact that the Heavenly Fire Sect, as a dominant force, has only one Daoist Master, and the Ten Thousand Stars Sword Sect has but one Immortal Master and three Daoist Masters, highlighting the disparity with the Mo Family.
To put it bluntly, all the forces of the Nine Northern Regions combined still would not be a match for the Mo Family.
This is the might of the Lord of the Northern Domain.
