Leviathans pride

When Alex was a boy he thought everything would be great till he grew up and the Apocalypse started. It didn't do with brimstone of earthquakes no it ended by fantasy becoming reality. Humans gained classes and systems and with it monsters and human nature. Years after almost all humans died Alex found a artifact in Egypt that changed everything.

Sent back in time with unimaginable power and a new name watch as the newly named Leviathan saves earth and becomes god.
