In addition to the book " Unrivaled Under the Heavens " mentioned, there was also a recommendation for a fantasy immortal cultivation novel with the same name " Unrivaled Under the Heavens ". The main character, Ye Xu, had a mysterious jade tower. He became a wizard through martial arts and a wizard into Taoism. Eventually, he became a wizard and martial artist who was unrivaled under the heavens, creating a legend of witchcraft. I hope you like my recommendation.
