Su Zhilan accidentally obtained a mysterious old ancestral book, which recorded unsolved cases of women across time and space. With each page she turns, her consciousness will be projected onto the bodies of different female investigators and help them solve the mysteries of their respective eras. As the mystery is gradually solved, she discovers that behind each time and space case, there is a dark force that runs through time and space, as well as secrets related to the fate of her family. Each volume is relatively independent but echoes each other, and finally achieves the intersection of time and space in the last volume, using the strength and wisdom of women to complete the ultimate redemption.
