The setting of this book is in Ancient China but completely fictional.
It is not a harem book and it isn't overly concentrated on romance. The male lead will not appear until the later part of the book.
Our female lead is a mage and her progress will be similar to cultivation.
She posesses 6 element: Water, Earth, Fire, Wind, Lightning and Ice.
Each element are divided into Early, Mid and Peak Stage.
The female lead's mother in-law is not oppressive or wicked but uses her tough exterior to protect herself from the limitations and oppression on ancient women.
The book is mainly about the collision of two strong headed women and a man who frequently gets caught between them.
