Your Royal Highness, You Don't Want to Lose Your Throne, Right?

Ron, a second-year graduate student, accidentally traveled to a magical world where the "Holy Spirit" existed. Became a low-level dungeon adventurer. Before he could figure out the situation, he encountered a crisis that was about to cross over again - encountering the collapse of the dungeon, he came to the 27th floor of the dungeon where powerful monsters gathered... Fantasy magic, majestic fighting spirit. There are even technologies that are different from cognition. These things seem to be closely related to the "Holy Spirit". Young Lorne didn't think so much. He just wants to live freely in this world. In this place swept by the torrent of fate, he survived tenaciously by relying on a book of "Revelation". However, the price on the other side has already been placed on the balance of fate.
