I recommend "Jade Fairy with Ice Skin". The female protagonist of this book is a peasant girl who was born without spiritual roots. She obtained an ice spiritual root after accidentally obtaining a strange jadeite jade hairpin carved with leaves. Her blood turned purple, and she had the heaven-defying effect of increasing the success rate of alchemy by 100%. On the path of immortal cultivation, she would explore the mysteries of longevity and achieve the pinnacle of ice. I hope you like my recommendation. Muah ~
