What Should I Do If I Accidentally Travel to Another World?

Fan Kairui, who was originally just a senior high school student in a vocational high school, accidentally traveled into a novel he had read. Became Charlie Oklisso, the young master of the Oklisso family who was destroyed by an accident. But the plot in the novel has now passed, more than ten thousand years! After that, he was rescued by Uncle Lot, the adjutant who claimed to be his father, Duke Les Oclisso. He also met after that. Dragon Princess Zovia Corvette. Witch senior Celcia Morya. Candidate for sainthood of the Church, Namitha Kami. Imperial Princess Leanne Westland. The elf princess Mariel Yuelu. Lilith Cernia, the ancestor of the blood race. Although adventure in another world is interesting, but now I am confused whether my choice is right? Is this all correct?
