Review Detail of Hilers in Cultivation Dimension

This is my first original novel that I worked on publicly. It takes place 2000 years in the future. Main Questions 1. Will there be a romance? Yes. 2. Will there be a harem? Yes. 3. Will there be face slapping? Yes. 4. Will the be tragedies? Probably not, this will be a light hearted novel. 5. Will there be s*x scenes? Yes, they are planned, the chapters will be marked (+18) 6. Will the MC be OP? Yes, I will he will be, but I will try to keep him leveled without blatant nerfing. I also sometimes read comments for inspiration, so never be shy about criticism. I will also try to explain things (or fix) things if necessary. I hope you enjoy the novel!
