Take Care of This Life, the Wind Will Come Late

[On the fifth anniversary of the April 15th fire, the microphone in the recording studio suddenly smelled of burnt food] Lin Wan's fingertips paused on the mixer. The sound test clip in her headphones was playing the phrase "Don't be afraid, I'll take you out" that she dubbed for the firefighting promotional video - before the vibrato of the last note faded, the sound of the alarm in her memory filtered in through her cochlea. On that night in 2020 when thick smoke filled the ceiling of the shopping mall, when her father finally dragged her to the safety passage, there was the same trembling sound with blood foam in his throat. The sound of the metal door being pushed open was like a dull knife cutting through the air. Lin Wan took off her headphones and saw a man in a white coat standing in the shadows, with medical tape taped behind his right ear. He tapped his knuckles on the old-fashioned tape player at her feet: "Teacher Lin's voice does have 0.3 Seconds more breath vibrato than the AI." He is Cheng Du, the "miraculous doctor who has retired from war" that has been widely rumored in the acoustic circle recently. Three years ago, there was an explosion in the Chemical Industry Zone of B City. He rushed in as an acoustic positioning expert of the rescue team, but lost his perception of "safety sounds" in the explosion shock wave - now any sharp sound will make him replay the scene of flames licking steel bars. "Mr. Cheng, are you here to ruin your job in dubbing?" Lin Wan squeezed the silver earphone pendant on her chest. It was the only relic of her father that was not burned in the fire. Cheng Du didn't answer, but instead turned on the black instrument he carried with him. The sound of ocean waves suddenly filled the current noise. "When you record a sample, your breathing rate will change slightly with your mood swings." His fingertips brushed behind her ear, "This unreplicable 'human smell' may be my medicine." When the steam coffee machine in Shengchao Cafe started to whistle, and when the noise converter in Shen Yin's laboratory lit up with blue light, Lin Wan was shocked to realize that this man who always said that she had "unhealed wounds in her voice" was the beast trapped in the sound barrier. And that old tape labeled "4.15 Shopping Mall Fire Drill Recording" was lying quietly in the voiceprint lock of Cheng Du's laboratory. They healed each other in the maze of sounds, until one rainy night, Lin Wan heard Cheng Du murmuring in his dream: "Why were voice-activated locks installed on the escape tunnels at the fire scene back then?" (In the BGM of the fire siren mixed with the noise of electricity, two people trapped in the sound are using each other's heartbeats to decipher a fire that has not been extinguished for five years. ) Purpose: Mutual redemption
