When a bronze box engraved with the remains of an anti-drug police officer emerges from the bottom of the moat, policewoman Chen Hongling, who is blind in her right eye, is forced to be involved in a war that spans life, death and time. From the spinal cord oil refining in Cixin Sanatorium to the remains of the candle dragon in the Tunguska Basin, she used the spine as the wick and the enemy's bone whistle as the fire to tear apart Pei Jiu's conspiracy before the "three-quarter hour" of the world-destroying ceremony. This is the ultimate showdown between an anti-drug blood feud and the law of entropy in the universe - only those who burn their spines can rekindle the spark of civilization at the end of eternal night.
