The book " Strange Man's Journey to Jianghu " had the Eight Ultimate Divine Arts of the Book of Changes.😋I recommend this wuxia fantasy novel to you. The protagonist Li Yu enters Jianghu and obtains the Body of a Strange Man, learning the Eight Ultimate Arts of the Book of Changes and the Ask the Sky Sword Technique. From then on, the martial arts world was dominated by the top experts. I hope you like my recommendation.
