Through the open window, you can see a corner of the community and the streets in the distance. Cars were coming and going on the street, and strange people were coming and going. People built cities, but they got lost in them.
"Leizi, what did you find?" Jiang Ruyi was a little out of breath.
Xia Lei shook his head, "No, but I always feel like something is wrong."
"What's wrong?"
Xia Lei said: "It's so clean here. There's not even any extra dust in the gaps on the floor. It looks like it's been vacuumed."
"Didn't Professor Zhang's maid say she didn't clean it?"
Xia Lei said: "The maid at Professor Zhang's house didn't clean it, but couldn't the murderer clean it? He was worried about leaving any traces. After killing Professor Zhang, he cleaned all the places where he moved. Your police technical team couldn't find him. It’s normal for him to leave even the slightest trace.”
"It's really possible, but..." Jiang Ruyi looked at Xia Lei with strange eyes, "The gap in the floor is so small, can you see how much dust is inside?"
Xia Lei avoided her question and said, "Where is the vacuum cleaner? Take me to see it."
"It's in the utility room. I'll take you there." Jiang Ruyi did not ask how Xia Lei could clearly see what was going on inside the cracks in the floor. She took Xia Lei to a storage room in the villa.
The storage room contains cleaning equipment, mops, vacuum cleaners, buckets, etc., as well as some other miscellaneous items, but they are all neatly packed.
"Has your police technical team checked this place?" Xia Lei asked.
Jiang Ruyi thought for a moment, "A colleague came to see it, but he only took a brief look and did not check it carefully."
Xia Lei walked to the mop and his left eye twitched slightly. The wooden handle of the mop was suddenly magnified in his left eye, and everything on the surface of the wood was clearly presented in his sight. He didn't use a magnifying glass, but he could see more clearly than a magnifying glass.
The handle of the mop was very clean, with no fingerprints or even a trace of water stains.
Xia Lei was even more sure of his guess, that is, the murderer must have cleaned the scene, and he even wiped the cleaning utensils used to clean the scene one by one after cleaning. There is only one explanation, because if Professor Zhang's maid cleaned the house, then what she wanted to do must be to rest instead of wiping the handle of the mop.
"Leizi, you are so weird today. Just now you were lying on the ground looking at the cracks in the ground, and now you are looking at the mop. Are you helping me solve the case?" Jiang Ruyi's curiosity became even more intense.
"Stop talking." Xia Lei walked towards the vacuum cleaner.
Jiang Ruyi raised her mouth in dissatisfaction, "You look like a detective, but you've never done this before, right? Are you okay? If we don't find anything, let's go for a walk. If we're lucky, we can bump into each other. Those two suspects. Hey, I'm talking to you, do you hear me?"
She would definitely not shut up, but Xia Lei did. While Jiang Ruyi was nagging, he had already finished checking the handle of the vacuum cleaner. The result is the same, the handle of the vacuum cleaner has been wiped down and is as clean as if it had just left the factory. His eyes suddenly fell on the dust storage tube of the vacuum cleaner. The black plastic of the dust storage tube suddenly disappeared from his sight, and the contents inside also came into his sight.
The dust bin has not been cleaned, and it still contains some debris, dust, carpet fibers, etc. A small piece of nail and a strand of hair embedded in the crack of the nail suddenly came into Xia Lei's sight. Not only that, he also saw a trace of dark red blood remaining on the nail!
Xia Lei's heart suddenly became excited, and he also imagined the process of the murder in his mind.
Professor Zhang heard a strange noise in the middle of the night and got up to look. The source of the sound was in the direction of the window. He thought the window was not closed properly and was about to close it. The murderer suddenly jumped in from the window, pushed him to the ground, and grabbed his neck. He struggled desperately, but was no match for the stronger murderer. His breathing became increasingly difficult, and his hands desperately clawed at the murderer's clothes and face. He scratched the murderer's skin, broke his nails, left blood stains, and a hair that happened to be torn off...
The killer cleaned up the scene, eventually wiping down the mop and vacuum cleaner handles. He may have opened the dust bin of the vacuum cleaner and looked, but he didn't find the nails hidden among the dust and carpet fibers. Or maybe it was because of time that he didn't have time to deal with the dust container. However, the reason is no longer important. What is important is that he was cunning and finally left very important evidence.
Xia Lei couldn't help but smile. Although he was not a detective, and he had no experience as a detective, with the extraordinary ability of his left eye, he was a born detective!
"Hello? What are you laughing at?" Jiang Ruyi couldn't hold her breath anymore. She moved closer to Xia Lei and followed Xia Lei's gaze and saw the black dust storage tube, but all she saw was It was just a bare dust storage tube, and you couldn't even see what was inside, let alone the small fragment of a fingernail.
"Uh... It's nothing, I just thought of something funny." Xia Lei said.
"You guy, I'm almost worried to death, and you're still thinking about funny things?" Jiang Ruyi hit Xia Lei angrily, "You are such a heartless, stinky man."
"Don't worry, I said I will help you solve the case." Xia Lei said, squatting down and taking out the dust storage tube of the vacuum cleaner, and then walked out.
"What are you doing?" Jiang Ruyi chased Xia Lei out of the storage room.
Xia Lei returned to the living room, found a newspaper, opened the dust bin and dumped the garbage inside on the newspaper. Then he carefully dug through the dust and carpet fibers to reveal the tiny fragment of a fingernail hidden inside.
"Are you talking?" Jiang Ruyi didn't notice the small piece of nail, and she couldn't understand what Xia Lei was doing.
Xia Lei carefully picked up the small piece of nail with a tissue, then handed it to Jiang Ruyi's eyes and said with a smile, "Did you see it? This is the evidence left by the murderer."
"This..." Jiang Ruyi stared at the nails in the tissue in stunned silence.
Xia Lei continued: "The blood on this nail should belong to the murderer, and there is also a hair of the murderer. With these two things, you can find the murderer's DNA, and then find the murderer's true identity from your police database. . With such a piece of evidence, you can make a detailed report to the superiors. You have all the witnesses and physical evidence in hand, and you have solved this case."
Only then did Jiang Ruyi come back to her senses. In her excitement, she suddenly hugged Xia Lei and kissed him on the cheek, "I knew it, I knew it... Haha, Lei Zi, you really are. My lucky star!"
The warm and soft squeeze, and the fragrant kiss like a dragonfly touching water, made Xia Lei freeze as if his acupoints were tapped, and his whole body felt bad.
As if she noticed something was wrong with Xia Lei, Jiang Ruyi suddenly let go of Xia Lei, her pink face was dizzy, and she said awkwardly: "I'm sorry, I'm too excited." She then diverted Xia Lei's attention. , "Tell me, how did you come up with the idea of checking the dust container of the vacuum cleaner? And how did you find such important evidence?"
"I've always been smarter than you, okay?" Xia Lei said.
"I admit this. Your grades have always been among the best when you were studying. Unfortunately..." Jiang Ruyi knew that Xia Lei tore up the admission letter from Kyoto University in order to take care of Xia Xue.
Xia Lei said: "Forget about the past and do what you should do."
Jiang Ruyi took out her cell phone, "I'm going to ask someone from the technical team to come over. With such important evidence, it will be easy to find out the suspect's true identity."
Xia Lei held her hand, "You are stupid. If you call back, Huang Changhai will interfere with it again. He can make the technical team slow down by doing whatever he wants. You were dismissed after a week, and he If we use the evidence we found to solve the case, it will be a great achievement immediately.”
Jiang Ruyi frowned, "What should we do?"
Xia Lei said: "Call the leader who promoted you and ask him to send someone over. You can also complain to him and make a small report about Huang Changhai. That Huang Changhai is always against you, don't you want to take revenge on him? This is an opportunity.”
"Gee, Lei Zi, I really didn't realize you were such a bad person. I'll call Director Xu right now." Jiang Ruyi smiled and dialed a new number.
"I'm going to the study." Xia Lei left the living room and walked to the study next to the living room.
There is an ancient desk made of golden nanmu in the study room, and two large bookcases, also made of golden nanmu. This kind of wood looks brilliant with golden light and flowing light and shadow. You can tell at a glance that it is valuable collection-level furniture.
"I'm afraid this desk and bookcase cost hundreds of thousands, right? This professor is really rich." Xia Lei thought in his heart, and then walked to the bookshelf.
There are many books on the bookcase, including professional books on archeology, literary classics, and miscellaneous notes. There are many types.
"Professor Zhang died because of a key. How valuable must the key be to be worth killing by the two suspects? The information Ruyi showed me said that the key might have opened some kind of warehouse door. The pattern on the key Maybe it's part of the map... With such a complicated matter, it's impossible for Professor Zhang to leave only that bit of research information, right?" Xia Lei's mind quickly shifted to the case.
In fact, if he finds the evidence left by the murderer, he will be done with it. However, he became very interested in the cast iron key. He couldn't help but think back to the scene of welding the key, and the faces of the man in the suit and the sexy girl. Standing in Professor Zhang's study, he had a very strange feeling that Professor Zhang might be hiding something, but that thing had not been found by the police or the person who killed him.
Finding things is not difficult at all for Xia Lei. His left eye twitched slightly, and everything in the study suddenly became "transparent"...
