This also includes the information left behind by Ulquiorra, the Black Dragon ancestor, in the Dragon's Legacy. This guy, once bored in the Material Realm, went to the Abyss to stroll around and ended up using this fishing method to kill a lucky lord of a medium-sized city.
If Udi were to comment... it would be that, clearly possessing enough hard power to occupy a major city in the Abyss, he still prefers such a boring fishing activity.
Incidentally, those occupying major cities in the Abyss are generally Demigod powerhouses.
Demigods have already touched upon the domain of the Divine Spirit. Or rather, they are Divine Spirits, albeit the weakest kind. In front of such beings, most of the Legendary are nothing but ants. However, a small portion of terrifying Legendary powerhouses, if under conditions that limit their power (such as in the Material Realm), indeed have the capability to resist the Divine Spirits, and even possibly slay them, becoming Godslayers.
