A rain of lightning

Given the rate of about one Supreme Being emerging every 100 years, it would take a staggering 200,000 years! 

On the bright side, at least Morpheus drew first blood from the Supreme Demon God.

"After the battle with Ares, the Supreme Demon God dropped from level 1999 to 1899," Apollo continued.

Good news: Humanity only needs nineteen more Ares to kill the Supreme Demon God!

Bad news: There's only one Ares.

Seeing Mike's keen interest in the Supreme Demon God tonight, Apollo patiently explained more, "Once the Supreme Demon God's level falls to 1000, any human Supreme Being could kill him."

Another piece of good news!

"1899, 1000," Mike counted on his fingers, "That's 899 levels to go, meaning we need nine Supreme Beings to battle the Supreme Demon God..."

Isn't that a bit too tough?
