My dear, are you looking for a novel about the white fox? Then I strongly recommend you to watch 'Breaking the Dao Companion, Starting with Aroma'! This novel was a light novel, a derivative doujinshi novel. The main character, Su Chen, was a transmigrator. After he ascended the throne, he unified the continent because of his lover, Aroma, just to make his lover happy. Although this book was mainly about Su Chen, the white fox was also a very important character. I hope you like my recommendation.😗
