I recommend two novels to otakus: " The Cultivation of Otakus " and " When an Otakus Encounters the World of Cultivation." The former was a Xianxia-modern cultivation novel, which told the story of how the otaku Yang Qingshan ascended to the throne of the Immortal World. The latter was a Xianxia-Cultivation Civilization novel. The otaku went to Lijiang in order to get rid of his loneliness and encountered a series of encounters. In the end, he was involved in a secret mission and traveled to another world. I hope you like my recommendation.😗
