Faced with Alister's words, the grand-level powerhouses who heard it became solemn as they knew what he meant by that.
After all, doing nothing and staying neutral was also a crime. It's even more of a crime than joining the wrong side.
Not everyone could stay in a neutral position without suffering from backlash. At least, with how petty the Goddess of Fantasy was, she would make it a big deal how the grand-level powerhouses in her world didn't even bother to support her.
Because of that, if those grand-level powerhouses ascended to the God Realm and Fantasia recognized them, they would have to worry about being turned into Fantasia's slaves.
As the top powerhouses of the Magic Fantasy World, it wasn't easy for them to reach the top. They also had pride in themselves and wouldn't allow themselves to be enslaved by others.
