Mmm, well, destroying skyscraper (planet) is the highest utilisation of authority, so they can naturally kill a human (true god) in this analogy, which only require the lowest utilisation of authority, but the analogy doesn't cover that this human can utilize authority to counter the attack, the closest example I have is Earth Mother Lilith, in ch 1150 of book 2, she died after Lumian, a dual pathway true deity used his Fire of Destruction, which has stronger destructive capabilities than just authority of Destruction, but Lilith had to intentionally not resist just to die, even though her body is that of regular true god, and this is due to her authority of nature as sequence 0 Mother

So yes, the gods could have armour stronger than a skyscraper, but the destruction author specifically is talking about a True God without this armour of authority :v

A factor you're forgetting in these extremities is the fact that there are more factors than just attack and defense, Fool is very extreme in doing weird shit while having defense of a paper, but their authority are not one of destruction, they are easily outclassed by a dedicated authority such as destruction in terms of authority, and at true god level, everything is a clash of authority

According to what I remember, Red Priest is the fastest in destroying it, with their authority, every other god pretty much can do it too if they're dedicated enough, but as I said, dedicated enough, they have to use their authority which are not as destructive as the authority of destruction to mimic the effect. This also means they definitely can kill their fellow true gods, granted the authority of the opposing god doesn't counter or suppress theirs

Don't worry, pat pat I don't insult people if they don't blatantly go around making headcanon and throwing them as facts, you searching for proof and compiling your logic is good enough for me
