There is a connection between the cards, and I am that connection.
After Ling Yang died, he was approached by someone who claimed to be a universal card system and threatened to make him a god. But what he never expected was that the 'person' Ling Yang hated most in the world was a god. How could he become the existence he hated the most.
Since he can't become a god, let him change the world and let God cease to exist.
