The Abyssal Demon Race had its own military hierarchy. At the bottom were Abyss Soldiers, and above them were Abyss Generals, followed by Abyss Marshals. Above the Marshals stood Abyss Kings, and the most terrifying of all were the Abyss Emperors.
An Abyss Soldier generally had strength between the 1st and 3rd levels of Spirit Manifestation Realm, while Abyss Generals usually matched the 4th through 6th levels and Abyss Marshals ranged from the 7th through the 9th.
Abyss Kings could stand up to Dao Resonance Realm experts, and Abyss Emperors were at a level comparable to the Life and Death Realm.
Fortunately, the Abyssfiend Warfront was only a medium-sized battlefield, so no Abyss Emperors were stationed there. The greatest threats were three Abyss Kings named Kharos, Morgath, and Veyran, each of whom had slaughtered countless human cultivators.
