"Xiao Yin, what else do you have to say?" Xue Yu looked back at Xia Yin, who had her head down, her long hair covering her face, the corners of her mouth were full of bitterness, in fact, he didn't want to say it at all, but persuaded Xia Yin to turn herself in, but he had long known that this idea was impossible to realize, and he knew very well that from the moment Xia Yin did not admit that he was the murderer, Xia Yin had already embarked on the opposite path of surrendering.

"Hehe, Xue Yu, even if your reasoning is correct, this only proves that the murderer is Min Zhou, and it has nothing to do with me." Xia Yin smiled, and a smile appeared on her face again, "Although we are a couple, Minzhou is not a fool, he will never kill Huihui for me, right?" I don't have a grudge against Huihui, and you see that we get along well on weekdays, do you think I will have a motive? Besides, the scene is a double secret room, if it is really me who killed Minzhou, then how can I use to get out of this secret room? ”

"You still don't give up. Don't you know me? If I don't have absolute evidence, how can I decide that you are a murderer, what I said to the little ghost just now is just to unravel the method and let everyone know the truth. Xue Yu sighed, and said that women have real and false faces, and they usually show their fake faces to others, and they will not show their real faces until the critical moment, but Xue Yu really doesn't want to believe that Xia Yin, who makes everyone happy on weekdays, is just a fake face, and now she is the real face.

"Since you are so confident, then you say, how did I kill Cui Minzhou from the double secret room? And what is the evidence? What about motivation? He and I were lovers, and there was no reason to kill him. Seeing that Xue Yu still thought that he was a murderer, Xia Yin finally became angry and yelled at him, as if she wanted to vent all the anger in her heart on Xue Yu's body.

"Little ghost, say it, I'm tired." Facing the angry Xia Yin, a trace of fatigue suddenly appeared on Xue Yu's face, and he handed over the entire reasoning stage to Zheng Hanfei again, he just wanted to stay quietly for a while, in fact, there was one thing he didn't understand, why Xia Yin killed Cui Minzhou and Lu Huihui, what was the reason for her to be so mad.

"In fact, the purpose of our first technique is not only what Xue Yu said, but also the important point is that this technique has a lot to do with the double secret room." Since Xue Yu gave it to himself, Zheng Hanfei was not polite, and continued to reason for everyone, "But there is no evidence, let's do an experiment to prove whether this method can be implemented." ”

"Wait! Wait a minute! Lin Guang interrupted Zheng Hanfei's words, his head was a little confused, there was no way, who called Zheng Hanfei's reasoning was too fast, he couldn't keep up with Zheng Hanfei's progress at all, "What is the double secret room has a lot to do with the method of killing Lu Huihui?" If you explain this clearly before you do that experiment, I won't be able to keep up with you. ”

"Huh? Superintendent Lin Guang, because you are an experienced case-handling person, don't you even see this? Zheng Hanfei still used a cold tone, but from what he said, he could hear that he was laughing at Lin Guang, and Lin Guang himself also heard it, he wanted to be angry at Zheng Hanfei, but the murder was not over yet, he didn't dare to make trouble at this juncture, so he had to try his best to be patient, hoping that Zheng Hanfei could tell him further what was going on.

"The great relationship means that the methods of the two cases are very similar." After staring at Lin Guang for a long time, Zheng Hanfei spoke, "Cui Minzhou's death was not killed by someone else, but like Lu Huihui, he touched something in the room and died, and it was something he had to touch, and because of this, he died." ”

"What is it?" Hearing Zheng Hanfei's detailed explanation, Lin Guang naturally understood what was going on, and hurriedly asked, "Moreover, according to what you said, Cui Minzhou's death has nothing to do with this double secret room, could it be that this double secret room was made by Cui Minzhou, and the murderer did not enter this room at all when Cui Minzhou died?" ”

"So to speak." Zheng Hanfei nodded, "As for what it is, let's have an experiment, this will convince everyone and the murderer, Superintendent Lin Guang, this time I want to trouble you to be the victim, please bring gloves, follow me into the scene of the crime, and then just listen to my orders." ”

I don't know what medicine is being sold in Zheng Hanfei's gourd, Lin Guang suddenly hesitated, but thinking that this could solve the case, Lin Guang was also ready to fight, and asked the police officer next to him for a pair of gloves, and after putting them on, he walked into the crime scene with Zheng Hanfei, and then everyone found that Zheng Hanfei closed the door and did not let anyone see the situation in the room, in order to prevent anyone from peeking, Xue Yu slowly walked to the door and monitored everyone, it should be said that it was Xia Yin's every move.

In less than five minutes, Zheng Hanfei walked out, just when everyone wanted to see what Zheng Hanfei's experiment was, Zheng Hanfei took the first step to close the bedroom door, but some sharp-eyed people still saw Lin Guang lying on the double bed at that moment, his eyes closed, as if he was asleep.

Just when someone wanted to ask Zheng Hanfei what was going on, Zheng Hanfei didn't know where to conjure a communicator, handed it to a police officer, and then said to everyone: "Because the sound insulation effect of this bedroom is very good, I took two communicators from Superintendent Lin Guang, one of which was placed in the bedroom, and the other was taken out, if something happened in the house, we would hear it as soon as possible." ”

"Xiao Hanfei, can I ask you what you are doing? Why did I just see Superintendent Lin Guang lying on Cui Minzhou's bed? Undoubtedly, Nan Tianyou belongs to sharp-eyed people, and at the same time, he also belongs to people with strong curiosity, afraid that Zheng Hanfei will not tell her because he is worried that others will know, Nan Tianyou deliberately took Nan Ruoxun to Zheng Hanfei's side, and asked in a low voice, hoping that Zheng Hanfei could tell himself, even if it was a little hint.

"I'm asking Superintendent Lin Guang to pretend to be Cui Minzhou." Zheng Hanfei said slowly, "Cui Minzhou was lying on the bed when we slammed the door open, and he also took sleeping pills last night, so I concluded that he should have been lying on the bed to sleep before he died, and after that, something happened that caused Cui Minzhou to touch a poison needle, resulting in death." ”

"What's the matter?" The more Nan Tingyou listened, the more confused she became, I really didn't know if Zheng Hanfei was too profound or she was too stupid, but that possibility meant that she didn't even have this ability to understand, and she was not suitable for being a detective at all, but a detective assistant or something like that.

"Of course, a voice sounded in the bedroom, a requiem that would bring people into the Yellow Spring. Well, it's almost time to begin. While speaking, Zheng Hanfei looked at the time on his wrist, and the corners of his mouth suddenly hooked up an extremely subtle arc, coupled with his expressionless face, giving people a gloomy feeling, if it weren't for the curiosity in his heart, Nan Tianyou would probably have left this five or six-year-old child with Nan Ruoxun.

"Listen carefully, Huangquan's requiem is about to sound! Five, four, three, two, one, zero! ”

As soon as the words fell, the communicator in the young policeman's hand sounded a loud noise, and the frightened young policeman almost threw out the communicator in his hand, and then the communicator sounded Lin Guang's voice, because the voice was too noisy, everyone could only hear the word "know", out of curiosity, Nan Tianyou opened the bedroom door, Zheng Hanfei did not stop her, let her open the bedroom door, but her eyes stared at Xia Yin, and found that the other party's face was a little gloomy, and the corners of her mouth hooked up a cold arc again.

When they opened the bedroom door, everyone saw Lin Guang'an lying quietly on the bed, his eyes were full of excitement, and he was putting one hand on the alarm clock on the bedside table. Cui Minzhou will die without knowing it. ”

"That's right." Xue Yu said, "According to my guess, I should have set the time of the alarm clock last night, installed a poison needle, and put sleeping pills in Cui Minzhou without his knowledge, so as to prevent him from waking up early tomorrow morning, and tell Cui Minzhou to lock the security door and bedroom door before leaving, so as not to cause anything to happen, so as to form a double secret room and kill Cui Minzhou without knowing it, and the only one who can do this is Xia Yin, who went back with Cui Minzhou yesterday, right?" ”

"If you still want proof, I can give it to you." Seeing that Xia Yin still wanted to speak, Zheng Hanfei walked up to her with the puppy in his arms, and said in a cold tone, "We haven't touched the alarm clock since we found the body, it stands to reason that the poison needle should be on it, but now it is gone, so the murderer should have walked into the crime scene during this time and took it out, but in addition to the police officers, only me and Xue Yu, and you entered the crime scene, and at this critical juncture, you should not throw away the poison needle, if I were you, I should put it in my pocket or bag, If you're really not the murderer, let's check what you're carrying with you to see if there's a murder weapon! ”
