Artist Qiao Ying transmigrates into a book, reduced to cannon fodder awaiting execution, and accidentally encounters Cen Yunyu, who is ostracized by the world. For self-preservation, she falsely claims to be his future lover. Cen Yunyu sees through the lie, but because she is familiar with his past, he travels alongside her, externally posing as a married couple. The two crack bizarre cases along the way and brave trials to head toward the Qingling Sect. Qiao Ying possesses a rare spiritual root, while Cen Yunyu hides his strength, biding his time to settle accounts with his past. The young girl initially wanted only to escape, but through their companionship, the two empathize with each other. This fake romantic entanglement born of self-preservation gradually gives rise to true feelings in a sweet 1v1 Xianxia romance exploration story.
