Drop
A few months later, the cataclysmic fights happening above the Central Continent finally started to die down. As is the case regarding beings of such strength, they're notably difficult to kill.
The number of techniques, treasures, and life-saving measures they had were seemingly endless, especially techniques.
Who among them hadn't been bored during their long life and decided to work on improving their capabilities instead of their cultivation? Who hadn't filled their spatial rings to the brim with all kinds of defensive treasures? Even if not all of them were Divine-Grade or above, they could still be useful.
In that regard, the people from the Mortal Realm were superior, given they had lived for so much longer.
Still, unless they could annihilate each other in a single strike, killing them was more of a chore than anything else.
