Unsolved Cases

In a seemingly ordinary city, a series of bizarre death cases formed a death game. Zhang Fan and Han Xue were outsiders, but gradually discovered that the key evidence in the case pointed to a non-existent person. Han Xue was even more horrified to discover that she seemed to have been prey from the beginning, which plunged her into a whirlpool of self-doubt. In order to solve the mystery, the two accidentally gained the ability to travel through time and space. However, each time-travel intervention can discover new clues, but it also triggers a new "butterfly effect", bringing more troublesome consequences. On the one hand, they have to engage in an intellectual game across time and space with the highly intelligent villain, who can always cleverly use the changes caused by time travel to continue to mislead the investigation; on the other hand, the protagonists have to make difficult choices between rescuing victims, finding out the truth, and facing moral dilemmas. Under the tight countdown of time, Han Xue's spirit is on the verge of collapse. Not only do they have to deal with numerous misunderstandings and suspicions from the outside world, but they also have to dig through the chaotic clues to uncover the truth behind the "non-existent person" and prevent the tragedy from continuing.
