"The Case of Her Incarnation - The 108 Days of a Straight Male Detective Dressing as a Wife" tells the bizarre experience of the straight male detective Zhao Lei. An accidental serious injury while handling a case caused his consciousness to travel through time and space and possess the body of the ancient heroine Su Qingdai.
During the 108 days in ancient times, Zhao Lei used modern criminal investigation thinking and repeatedly solved strange cases as a widower: from the mystery of a groom hanging in a secret room to the strange plot of poisonous mushrooms killing people, he used straight-male hard-core autopsy methods to subvert the world's understanding of widowers. In the process, he and the cold-faced prince Xiao Jue got to know each other. From the initial dislike of each other to working together to investigate the case, the two gradually fell in love while solving the queen's poisoning case and the cult's sacrifice conspiracy. Zhao Lei even discovered that his time travel was closely related to a sacrificial ceremony that lasted for 108 days. This was a conspiracy spanning ancient and modern times.
After successfully smashing the conspiracy, Zhao Lei returned to modern times, but on the 108th day when he woke up in the hospital, he reunited with a painter who had the same appearance, temperament and even habits as Xiao Jue. The bond that spans time and space allows the two to make an agreement and wait for their fateful reunion.
In the end, the ancient Xiao Jue disappeared after completing his mission, and the modern painter Xiao Jue also passed through time and space. When two souls that have experienced many vicissitudes of life finally break through the barriers of secularity and time and space, they sit side by side in the sunset with gray hair. The past cases, the adventures of time travel, and the deep love have all turned into the gentlest waiting in the years. This legend that started in "her body" and ended in "his heart" has become an affectionate footnote that spans thousands of years.
