Signs of tribulation started to appear near every single invader.
Eternal Tribulation, Apocalypse, was a self-destruction skill. A universe self-destruction skill. When the universe itself negated all the life on the universe, the only result for the living being was to die.
However, only someone like the Mysterious Expert would be able to use it, not even Alrein as the universe creator could use it.
In fact, out of all universes in existence and that existed, the Mysterious Expert was a unique existence, so that was the first time that skill had been used. It would be alright to say that the Mysterious Expert created it, although if another existence like that appeared, it would be capable of doing the same.
The Mysterious Expert was an anomaly.
The Mysterious Expert was someone, or maybe saying something would be more accurate, that shouldn't be capable of existing yet existed.
