I recommend the following novels to you: " Transformed Nine-Tailed Fox Fairy that Traversed the Other World ": A story of a otaku turning into a nine-tailed fox otaku and gradually becoming a strong person with the help of the system. The author was the last person to wake up from a dream. Onmyoji Apprentice: A light-hearted and humorous ancient mythological world, where the protagonist becomes an Onmyoji Apprentice. The author was Yin Ji. [I'm Really a Secret Manual]: The story of an otaku turning into an Evil Warding Sword Manual. The author is I'm Really a Superstar. These are the three novels I recommended. I hope you like my recommendations.😗
