Su Wan, a modern corpse restorer, traveled through troubled times and became the fake daughter of a marquis who was abandoned by her family and exiled to the streets. In order to survive, she proposed herself on the street and married Xiao Jue, the rumored dead king of Zhenbei, and reached a contract marriage: she would "keep his house" for him as a princess and handle the mysterious corpse case, while he would keep her safe and give her the space to display her skills.
Su Wan relied on modern bone examination, embalming, and body restoration techniques, starting from the case of sinking bones in the dry well of the royal palace, and repeatedly solved strange cases. From the despised "Princess of Filth", Su Wan became a capable person who can resolve unjust cases and put the souls to rest. Following the male protagonist to the border, she used her funeral knowledge to save lives, control plagues, and bury soldiers. She grew from a bone collector to a battlefield guardian.
After returning to Beijing, she opened a righteous village, established rules, integrated modern funeral concepts into the troubled times, gathered the underlying information network, and teamed up with Xiao Jue to uncover the shocking conspiracy of the prince seizing the legitimate son, the poisoning of the late emperor, and the secret medicine of the previous dynasty. In the end, they helped the new emperor ascend the throne and relieved Xiao Jue's poison. The two gave up their power and used Yizhuang to pacify the dead souls in the world and guard the northern border.
