Cheng Shubai, a professor of applied physics at Linchuan University of Technology, has the ability to restore any "abnormal phenomena" to physical parameters - angle, frequency, temperature, refractive index. He does not believe in intuition, only in formulas; he is not good at the human mind, but he is proficient in the interaction between light and matter. Lin Ye, deputy captain of the Criminal Investigation Detachment of the Municipal Public Security Bureau, is good at interrogation and scene reconstruction, but when faced with "impossible crimes" such as secret rooms, doppelgangers, and spontaneous human combustion, her experience will be completely useless. She needed Cheng Shubai to bring out a laser interferometer, a polarizing filter, or a shape memory alloy wire from the laboratory to dismantle the murderer's "supernatural performance" into a physics problem accurate to three decimal places. The spontaneous combustion of the human body is "boiling from the inside" caused by microwave directional heating; the secret room's penetration through the wall is the "remote anti-locking" of the laser-triggered memory alloy; the surveillance clone is the "optical invisibility" woven by Pepper's illusion and polarized light. The murderers are not perverts, but engineers, doctors, and optical researchers - they use knowledge to kill people and use formulas to write suicide notes. Cheng Shubai had other selfish motives in pursuing these cases. Three years ago, his favorite doctoral student Jiang Chao died in a "liquid nitrogen leakage accident." But Cheng Shubai found Jiang Chao's handwriting, Jiang Chao's formulas, and Jiang Chao's unpublished research in the murder weapons of each new case. The person who killed Jiang Chao was a person who knew physics better than him. When science itself becomes both a murder weapon and an antidote, Cheng Shubai and Lin Ye search for the truth hidden behind the formula between microscopes and surveillance videos. Light doesn't kill. But those who use up the light will.
