If that was true then then supplying extra mana during his system run “upgrades” wouldn’t do anything but you can also see the system actively sucking in more mana at the end of the second upgrade since nova couldn’t supply enough and system can’t produce it
There was “some” mana on earth otherwise what was Aron using to power his magic before the mana converter existed? It’s just that it was so low as to be imperceptible and have no affect on anything
