Desire Is the Key to Saving the World and Becoming a God

I was once the strongest person in the human race, and I proved the Tao through my good deeds! But during a battle with the Demon Lord, he was defeated by the Demon Lord's beauty and died... When I was reincarnated, I met the god from a hundred thousand years ago. With his help, I was reborn and gained a desire system. As long as my desires are fulfilled, I can become stronger? Prosperity and wealth? A sense of superiority? Pretty lady? I want them all! Demon Lord? Wait for me, I'm back!
