On a rainy night, detective Lin Shen ran into a black car with a death photo in the garage. In the photo, Su Wan, the female victim of the "Rainy Night Corpse Dumping Case" three years ago, has her eyes open, with half a silver armor plate stuck between her fingernails - the key piece of evidence that was once deemed "lost" by the police, is glowing strangely at the moment.
"Under Su Wan's fingernails, there is the answer you want to know." The voice from the voice changer was like sandpaper scraping against the eardrums.
Lin Shen's PTSD broke out instantly, and his wrist was scratched with bleeding marks. He recalled the night when his partner Chen Mo died, who held his hand and said, "Be careful with women wearing silver bracelets." He recalled the writing in Su Wan's diary, "They say I am an 'imperfect work.'" He also recalled the trembling words of forensic doctor Lao Zhou, "That fiber is not like something from the earth"...
Su Wan's case, which was characterized as a "suicide" three years ago, actually had a secret connection with the "Cocoon Fang" organization. This mysterious group, which claims to "purify mankind with the laws of nature," specifically targets highly educated women and uses the pupal shell of the golden-spotted swallowtail butterfly to implant "moral guilt" into them, allowing them to "complete evolution" in the midst of collapse. Lin Ruo, Fang Qing, Professor Chen... All the victims had left traces in "environmental protection charity", and the golden-spotted swallowtail butterfly saved by Su Wan was the key to solving the mystery.
When Lin Shen discovered the imprisoned "living experimental subjects" in Professor Chen's laboratory, when he received the Papilion butterfly specimen (with a built-in positioning chip) from the "cocoon room", when he realized that his PTSD was actually the "early warning system" that his partner had sacrificed his life for - he finally saw clearly: the evolution of the so-called "perfect human" was just a crazy experiment fed by the lives of innocent people.
What suffocated him the most was that the pupalin detected in Su Wan's body was highly consistent with his own DNA. In Old K's laboratory diary, it was clearly written "Experimental Subject No. 003: Lin Shen, evolution progress 30%."
The dark cocoon will be broken, and the truth will be colder than death. Lin Shen held the silver armor tightly, and the blood from between the nails dripped on it, glowing the same golden color as Su Wan's corpse - this time, he was no longer a bystander, but the "prey" selected by the "Cocoon Room".
When the laboratory in Butterfly Valley exploded, when the central building in Geneva collapsed, and when Su Wan woke up from the nightmare of "breaking the cocoon", Lin Shen finally understood: the so-called "purification" is just the strong devouring the weak; and the glimmer of humanity is precisely hidden in those "imperfect" cracks.
But the real terror has just begun...
