Devils, before reaching the Divinity Transformation Realm, typically have a significant advantage over human cultivators in combat.
Ordinary devils, if equipped with heavy armor and war swords like human cultivators, are sufficiently powerful to combat those in the Gang Condensation stage.
However, this advantage gradually diminishes after entering the Divinity Transformation Realm.
Divinity Transformation Cultivators, relying on the advantage of flying swords, can often suppress Middle-level Demons.
Only those Middle-level Demons who are skilled in speed and defense can quickly close in to obliterate the Divinity Transformation Cultivators.
As for Primordial Spirit True Monarchs...
The disadvantages of Upper-level Demons become increasingly obvious.
Aside from avian Upper-level Demons, other Great Demons of the same rank can only passively withstand the onslaught when facing a Primordial Spirit True Monarch.
