Well, without having read it directly, if it's a light novel about a lizard king, it could be about his rise to power. It might detail his battles against other creatures or kingdoms. There could also be elements of magic, politics, and perhaps a love interest in the story. For example, he could be fighting to protect his land from invaders while also trying to win the heart of a princess from a neighboring realm.
I'm not entirely sure specifically what the 'lizard king light novel' is about as there could be many interpretations. It might be a story centered around a character known as the lizard king in a light novel setting. Maybe it involves adventures, quests, or a unique world - building with the lizard king as a key figure.
