In order to find out the truth, Jinchen and Shao Huai brought Xu Yi back to 306.Xu Yi huddled in the lazy sofa in Room 306, hugging the pillow tightly in his arms. Perhaps because he finally found someone he could talk to, Xu Yi didn't dare to shed tears, for fear of missing any details.Jinchen kindly gave the guest a candy and said, "Tell me, did you see it last night as well? Maybe... you saw something more than us?""last night……"Xu Yi's fingers unconsciously plucked at the holes in the sofa, and cotton wool leaked out from between his fingers. "I was walking down from upstairs, wanting to go to the convenience store to buy snacks, and I saw someone on the sixth floor... killing someone."Recalling that scene, Xu Yi wanted to retch, but suddenly he grabbed the lemonade on the coffee table and gulped it down."The murderer... was wearing a heavy raincoat and pushed Uncle Song towards the fire escape."Shao Huai suddenly handed over the phone: "Is it this kind of raincoat?"On the screen was a raincoat hanging next to Uncle Chen’s cleaning car, with fish scales on the cuffs. They had just taken the picture.Xu Yi shook his head: "That one is darker... like... like the kind used on construction sites, but it could also be that I didn't see it clearly."Jinchen: "Did the maintenance worker struggle?""No." Xu Yi's voice suddenly trembled, "He's like... like a puppet.""By the way, the murderer looks taller than me." He gestured."after that……""I... I smelled a fragrance." Xu Yi's pupils began to dilate, "I don't know anything after that."Shao Huai opened his notebook and wrote down something. "You said you've lived here for a long time, and the people in this building... aren't that great?"Xu Yi smiled bitterly: "Let's talk about the people downstairs. Grandma Chen always burns paper money in the middle of the night. The fishy smell in Aunt Zhao's house is enough to make people vomit. She also likes to chop fish in the middle of the night and never lets anyone say anything. There are also a few gangsters."Shao Huai and Jin Chen got information about many people in this apartment building. The more Xu Yi talked, the more strange it felt. Before leaving, he couldn't help asking, "Are you police officers?"Jinchen: "We are the unlucky ones who are afraid of being silenced by the murderer."One of the unlucky guys, Xu Yi: "..."Okay, it would be rude to say any more.During the next half day, nothing strange happened except that when Shao Huai was familiarizing himself with the terrain of the apartment, he accidentally ran into the burly man hurriedly running downstairs with the cat bag in his arms.To be precise, I didn't run into anyone else.It was as if the rainstorm had trapped the residents of this apartment.-"Tatsuko! Wake up! Something happened!"Shao Huai rushed into Jinchen's room, forced open Jinchen's sleepy eyelids, and shoved the phone in front of him.His voice was trembling: "Look! It's a ghost!"Jinchen: "..."What a hell.He pushed Shao Huai away, and said with a rage as if he had just woken up, "You are sleepwalking.""Look at the time, Chenzi! Today is May 5th, the sixteenth day of the lunar calendar, Tuesday!"Jinchen then opened his eyes and looked at the date on the phone screen. His heart tightened slightly, but his face remained expressionless.He looked up at Shao Huai blankly, and said lightly: "What are you talking about? What about yesterday and today?"Shao Huai widened his eyes, as if he couldn't believe his ears.He was so anxious that he almost jumped up, and his voice rose an octave."Yesterday was Wednesday! Today is Tuesday! How did we go back to the day before?! Don't you remember?""Yesterday, Wednesday, we saw the body on the 6th floor, met Xie Guan, and got familiar with the topography of this building! Don't you remember?!" Jinchen nodded seriously, trying to recall: "Hmm... I don't know."Shao Huai was completely panicked. He scratched his hair and said incoherently: "Could it be... Could it be that I am the only one who still remembers?! Impossible!""If it's true as you said, it means you are the chosen protagonist and the future light of the police academy."Jin Chen pretended to be deep, raised his hand and patted Shao Huai on the shoulder, "Come on, young man."Shao Huai: “…”If this guy still can't hear it, then he has been a brother to Jinchen for so long in vain under his taunting skills."Your uncle!"Shao Huai finally breathed a sigh of relief.What's the point of being the chosen protagonist? If he really has the courage to stand on his own, he won't be willing to be the eternal second behind Jinchen....Oh, third brother.Thinking of his old friend Xie Guan who was still in 301, Shao Huai silently moved himself back one place."It's getting more and more weird, Chen! What should we do? Will everything be fine if we leave this weird apartment building?"Jinchen lifted the thin quilt and opened his cell phone to take a look.The time was refreshed to the day before the maintenance worker died."Today is Tuesday, and the body on the sixth floor is still alive."After Jin Chen finished speaking, he raised his eyes and looked at Shao Huai, "We still have a chance to save him.""Yeah... Damn it, that's a life, save it, we must save it!"Shao Huai realized this and his fear was dispelled. Suddenly he remembered something and quickly ran to open the window."Why is it still raining heavily?"Shao Huai muttered, "Did it rain on the Tuesday before yesterday? I don't even remember it."When he heard Jinchen coming out of the bathroom, Shao Huai turned around and looked at him, "Hey, where is he?""Here, let's go to Room 301 to see our misguided teenager Xie Xiaoguan." Jinchen put on his windbreaker jacket and lazily opened the door.Shao Huai: “…hiss.”Why do I always feel that Chenzi is weird when meeting Xie Guan again this time?Kind of flirty.Shao Huai felt like he was hit again.-301.Jinchen's way of knocking on the door was also very unique, neither fast nor slow, and with a bit of rhythm.It sounds very infuriating.There was a fourth knock on the door, and Xie Guan opened it quickly, "Are you done yet?""It's not over yet." Jin Chen answered casually, and looked at the grumpy boy from his messy hair to his ankles, and then reached out to press down a strand of hair that was sticking up on Xie Guan's head."Happy Tuesday." Jinchen said.My wife looks obedient when she doesn't speak."…What day of the week?"Xie Guan was stunned for a moment with an unhappy look on his face, and his eyes met the phone that Jinchen was holding up.He looked back with a wooden face.The calendar on the wall was a little dusty, and the page that should have been torn off reappeared: Tuesday, May 5th.Xie Guan: “…”"That's great, the three of us are still together." Shao Huai finally found an opportunity to interrupt and breathed a sigh of relief.Xie Guan really wanted to pack up and send these two away.But due to the strange facts, I had to let it in.The living room was deserted, with some pencils and white papers scattered on the coffee table and the sofa. As soon as Jinchen looked over there, they were taken away by Xie Guan and tidied up.
