John woke up one day to find he was summoned to another world that is filled with magic, monsters, and interdimensional invasions. The problem is that he was not a hero but an accidental extra in the summoning process. Next he found himself as a dungeon core in the middle of nowhere of a massive bog. Over time he will find himself as the patron god of a powerful nation. This is my first story so there is a high probability it to have a lot beginner mistakes and advice is welcome.
