This is a really good anime with its backstory stemming from the Qin dynasty which was China's first dynasty. This is a story that follows both fiction and non-fiction. Most of what was in the first season are historical events. However, there are some changes to fit the story of a mythic legend named Yu Qin. As the story progresses, Yu Qin becomes stronger and in season 2 meets a well-known Chinese legend, Sun Wu Kong. Well in the anime he wasn't named that but his weapon and looks are inspired by Sun Wu Kong. This has roots in Chinese epics such as Xi YouJi. I think that this anime is really good as a native speaker, however, there is a bit of loss in translation in English so I had to wholly watched it in Chinese. I do believe that this is a phenomenal Chinese anime that sees Yu Qin's growth as he seeks to become a god through his trials and tribulations.
I do believe that this is anime is a 9/10 all around for me. Do give it a try.
