In his previous life, he was trapped in the fog, framed by others, and eventually buried in a deserted temple. His soul was entangled in strange objects, and he watched helplessly as the unjust case fell to the bottom and his relatives and friends suffered. Once he was reborn, he returned to a time before the tragedy occurred. The evil spirit lingering around him had not dissipated, but it became a basis for spying on the strange truth. The sobbing of the old house in the middle of the night, the smell of the broken ground in the barren tomb, and the erased records in the files all point to dust-shrouded secrets. He hides his edge in a meek manner, and uses fragmented memories of his past life to explore the mist between yin and yang step by step, and solve unsolved cases involving life and death. His fingertips touched the cold bones, and he heard the whispers of the dead souls in his ears. In this life, he not only wanted to find out the mastermind behind the scenes and wash away the grievances of his previous life, but he also wanted to protect the people he cared about and prevent regrets from happening again. It's just that the road between Yin and Yang is close, and people's hearts are more dangerous. Those seemingly unrelated and strange events have already been woven into an airtight net, and he is once again involved in the whirlpool of fate.
