I Conquer Hell and Heaven With 666 Trillion Coins

Beyond the sky lies the boundless Aether, a realm of beauty and the divine; at the very depths of the underworld lies the Nether, a realm of unimaginable horrors. And at the centre of it all stands one person. A person with an unimaginable fortune, who holds the right to rule over all three realms. As the system in his hands glitches and it continues to take his rewards, the only thing he can do is use his wits and his wealth to rule over the realms. Gods? Goddesses? Titans? Demon Lord? Who on earth are they!? Only Dean can rule over them. — Description from novelcodex.org
