The three of them are like precisely meshed gears: Lin Mo breaks the situation with intuition and demarcates the direction of investigation; Chen Hao uses technical support to weave a network of evidence; Han Yuqing starts from death itself to correct the deviation of the time dimension. Lin Mo's "anti-common sense reasoning" (suicide blaming), Chen Hao's "micro-object tracking" (fibers and scratches), and Han Yuqing's "corpse language deconstruction" (rigor mortis time difference) form triple confirmation. Their opponents are not only murderers, but also the abyss of human nature alienated by wealth. While solving the mystery, each character is also exploring the boundaries of his or her own understanding of "truth and justice."
