My name is Shen Shen, codenamed Bai Falcon. I say I am a sniper, but in fact I don't shoot people, I shoot "historical echoes." These days, human beings' extreme emotions will leave afterimages in reality. Anger, fear, and regret will suddenly materialize in three to five years and be repeated to you in the city center. My job is to get in, tear things down, and turn off the lights before the replay gets out of hand. There are three teammates in total. One has good hearing and can hear the fear of 43Hz, but the tea cup is always cold. A 188, facing all monsters, raising a pot of plants that no one knows the name of. There is another one whose profile says he is 22 years old (but I don't believe it). You can hear the "part that didn't happen" in the reverberation. I never wanted to be a captain. The number of the original captain is still in the system, and I have been an "agent" for two years. Something happened tonight in the old town of Jianglin City. Black rain fell from the ground to the sky. A residential building hung upside down in the air. The balcony faced east. To the east was the No. 7 Primary School. A gray-blue children's sweatshirt hung on the balcony. The General Administration said: Level 3 reverberation incident. Zero said: There are people inside waiting for people to go home. I said: Come in. This is the story of the Puppet Squad, which does not save the world, but just allows certain histories to finally shut up.
