Xuan Tianxian respected Chu Lingxiao, but when he was going through the last tribulation of ascending to the gods, he was betrayed by his best friend, everything collapsed, and his soul was scattered.
He thought he would fall into nothingness forever, but he didn't expect that a remnant soul would travel through endless time and space and be reborn in a modern city called "Blue Star", possessing the body of a young police detective who had just died in the line of duty.
In this world, there is no spiritual energy and no Taoism. Mortals are struggling to survive for hundreds of years. However, a series of bizarre "perfect crimes" overturned his cognition: the rich man who died peacefully in a secret room had bloody peonies blooming out of thin air; the body of a superstar fell from a high-rise building at midnight, and no trace of damage could be found on the body; the stolen antiquities from the museum were turned into powder in full view of the public...
In these cases, ordinary criminal investigation methods are helpless, but in the eyes of this former immortal, they have left clear "trace of the Tao".
