Apocalypse, my boy.

It's a little weird that a man with 1000 magic power could summon him, but it'll take 10,000,000 to go home. I wonder if sacrificing your life counts for way more than you can produce on any given day, since you'd arguably have many more days if you hadn't done so?

man.....even if he says he only used 0.1% of his power that's still beyond normal .-.
if 1000 can be considered one of the greatest mage the MC 0.1% easily topped that by 8 times xD
