I've recently started to become interested in the five Wu Xing elements (wood, fire, earth, metal, water), and I was reminded of a xianxia series I've read several years ago. However, I can't remember what the title was. All I can remember from it is that the MC could use all five elements and had some sort of cultivation technique where he forms "totems" within his body in the shape of the Four Symbols (Azure Dragon, Black Tortoise, etc.). A distinctive part I remember is that he used an elephant to represent earth instead of the Yellow Dragon, and his lightning abilities were categorized under the Wood element. I'd really appreciate any answers, and I would also enjoy any recommendations on other novels with a major focus on the five elements.
