In my previous life, I was Su Qingyuan. I was trying to get closer to the truth in investigating a serial mutilation case, but was pushed off a high building by someone I trusted. When I opened my eyes again, I went back to three months before the murder, still holding the unsent autopsy report in my hand. This time, I put away my innocence, used a forensic knife to cut through the lies, and relied on my past life memories to avoid traps. I met the 19-year-old detective Lu Xingye. He called me "sister" and protected me with his blood. He accompanied me to fight against the cunning mastermind, the green tea mole who pretended to be innocent, and the psychologically twisted serial murderer. From the disillusionment of ideals to working together to hunt down criminals, we stand side by side in the bloody fog, and we will eventually expose all sins to the sun.
