Tang Li, a modern zoo keeper, accidentally passed through the book and became the newlywed princess of the regent Pei Yunjing. She was involved in a life and death crisis from the beginning. With her ability to understand animal language and her special body scent, she not only received help from the Wolf King, White Cat and other animals, but also became the only "antidote" to relieve Pei Yunjing's old illness. The two gradually fell in love with each other as they escaped and hunted, tested and guarded, and joined forces to uncover the conspiracy between the palace and the royal family, and rewrote the doomed tragic ending of the original book.
