On a day of great cold, Chen Jiu, the corpse collector of Crock Alley, was scavenging in the garbage mountain. He used his talent of "reverberation of all things" to intercept a piece of fine gold, and he identified the location by listening to the sound and repelled the maniac Zhang who attempted a sneak attack. After returning home, Chen Jiu used the lamp oil exchanged for fine gold to worship the "fire stick" (the remnant soul of the Tianhe sword head) behind his back, showing his helplessness as a "sword slave". Yin Xizhao, who was walking on the Hanging Sword Mountain, followed him and wanted to force him to buy a fire stick. When Chen Jiu was struggling between money and saving his life, the innate cold poison in Yin Xizhao's body was detonated by the evil spirit. She lost all her spiritual power in an instant, froze the courtyard, and fell into Chen Jiu's arms. The fire stick clamored to refine the "cold tonic" delivered to his door, and Chen Jiu fell into a dilemma of freezing to death or saving others.
