"When criminal investigation consultant Su Mingyuan solved the 13th murder case in a wedding room, the blue rose of the deceased suddenly bloomed in front of his eyes - only then did he realize that every murder case he solved was repeated in the "Mirror Realm" of parallel time and space."
Su Mingyuan, known as the "eye of truth", can see through all lies, but cannot recognize that the iris of his left eye comes from the forensic doctor Lin Xia, who he has a crush on. Whenever he identifies the real murderer in the real world, he will fall into the mirror world in his dream and meet the guide Nightingale, who is made up of data streams - this NPC with the same appearance as Lin Xia is guiding him to investigate the supernatural revenge of the victims after their "rebirth".
When the marriage contract curse of the serial killer "Puppet Master" spread to reality, when Nightingale began to touch his scar against the procedures, when Lin Xia's scalpel suddenly pointed at the wound that existed only in the Mirror Realm... The Rose Murder Theorem that spanned the two realms finally tightened its thorns on the detective himself.
