Yet no matter what people perceived him as, the fact he was someone who brings about death was undeniable. From that instant he started, he would kill, slaughter, and murder each and every person by assessing and dissecting them until eventually, the end result will be that all life have vanished. Now that he was physically "nothing", there was no one else whom he could shift his focus on the other side.
At least, no one that was present right now.
The world that had become a wasteland after the slaughter was one where only he stood. That Monster--Magsaion, looked onwards without looking back on his tracks, staring from the death earth to the starless sky.
Come on out. You're next. He barked silently to the one who had yet to show themselves. That man's unrestless spirit told him it was not yet over.
If anything, the real one had yet to appear. The source of everything, the Throne of God lies in the depths. And it went without saying that it is a realm where supernatural overlaps with supernatural. Thus, only those who meet the qualifications can reach it let alone pinpoint its exact coordinates.
And by qualifications, it means having the aptitude for Hegemony as well as a level/rank not inferior to that of the current God. In other words, only when both dispotision and strength are present will the gates open up. However, Magsarion did not satisfy the former condition. Though he had no issues with strength/power, he lacked the mentality to create and rule a new world.
His act of annihilation was also meant to fill in that gap. if "everyone" were killed in the universe, it would cause everything to shrink and all phenomena would be concentrated onto a singular point. To put in a metaphor, it would be like hunting where you corner your prey and block off its escape routes. The logic was simple, and it was something anyone could have come up with. But what made it astonishing was the naivety with how he was seeing it through to the end. No matter what the future holds, it's unlikely that anyone would have been able to do the same as Magsarion did.
This was undoubtedly and unpredently Meifu Madou. Perhaps Kami/God herself wanted to witness it all and thus didn't bother to intervene.
