The monkey checked the vicinity of Lu Changfeng's home and found a surveillance camera at the entrance of their community. This is the only one door that can enter and exit this community, so you can only enter and exit from here. To know whether Lu Changfeng was in and out of the community on the day of the crime, just look at this monitoring.

The monkey tuned the surveillance until five o'clock in the evening, fast-forwarding and looking back.

"Look, this is Lu Changfeng going home." At about six o'clock, Liang Fanxin saw Lu Changfeng, who was dressed in casual clothes, walking towards the community with two bags of things in his hands.

"He said that there was no class that day, so he bought groceries early and went home, which seems to be right." Lu Yifan also nodded and said.

A few people continued to look at it, carefully observing everyone who came out of the community, and carefully identifying whether it was Lu Changfeng or not. Because the next time should be the time when Du Lei is about to be killed, if Lu Changfeng has not appeared, then there is no time to commit the crime.

"Team Lu, Du Lei's time of death has passed, and Lu Changfeng didn't come out of the community at all, it shouldn't be him." Liang Fanxin looked at the time and said to Lu Yifan.

"Don't worry, keep reading." Lu Yifan said with a cold face. Although Liang Fanxin didn't understand what else he was looking at, looking at his determined appearance, Liang Fanxin could only follow along.

In this way, several people went from ten o'clock in the evening the previous day to six o'clock in the morning the next day, and Lu Changfeng finally appeared in the camera again.

Now Lu Changfeng is dressed in professional clothes, carrying a bag in his hand, and his clothes look like he is going to work.

"Team Lu, are you waiting to see this?" Liang Fanxin looked at Lu Yifan with a relieved look and asked him.

"Well, it seems that he really hasn't been out since he came home yesterday until the next day." Lu Yifan nodded and said to Liang Fanxin, "This can prove that he is not present, and it seems that there is really no suspicion." ”

"Okay, then I'll let Lu Changfeng go now, and tell him by the way." Liang Fanxin hurriedly said.

"Don't be in a hurry." Lu Yifan interrupted Liang Fanxin's hurried pace to go out.

Liang Fanxin has been made a little sensitive by him, every time he is like this, he is obviously very happy in his heart, and now that he has any evidence, he still doesn't hold on to him, why.

"What did the cufflinks you grabbed look like that day?" Lu Yifan's mind kept flashing Lu Changfeng's hands covering his face, and the cufflinks were so familiar.

"What's wrong?" Liang Fanxin opened the information in his hand and showed it to Lu Yifan.

This cufflink! Lu Yifan nervously snatched the photo in Liang Fanxin's hand, which was so imaginary from the buttons in his impression, he hurriedly ran into the interrogation room, grabbed Lu Changfeng's hand, and compared the cufflinks in his hand with the cufflinks in the photo.

Same!

Lu Yifan's hands clenched into fists, and he began to turn white with direct force, and from the depths of his throat, he said with difficulty: "It's you?!" ”

Lu Changfeng didn't see a trace of panic when he saw the photo in his hand, his eyes looked at Lu Yifan lightly, and asked in a questioning tone, "What's wrong?" ”

Lu Yifan saw that he looked unaware, and he didn't know if what he said was true or false, "Your cufflinks." ”

Lu Changfeng looked at his cufflinks strangely, and asked a little puzzled, "What's wrong with my cufflinks?" As he spoke, he looked at the photo in Lu Yifan's hand, which was exactly the same button as his hand, he couldn't help laughing, and said helplessly: "Brother, won't you come to slander me because of this photo?" Such cufflinks are the same as long as the person who buys this brand of clothing. ”

Lu Yifan was stunned, what he said was indeed not wrong, anyone could become the owner of this cufflink, he let go of Lu Changfeng's hand and stared at Lu Changfeng with a peaceful look on his face, as if nothing had happened.

"Team Lu, why are you running so fast!" Liang Fanxin was a little out of breath and caught up, and pulled his hands on Lu Yifan's arms.

Lu Changfeng looked at the visitor with a smile, and found that Lu Yifan did not shake Liang Fanxin's hand away, his eyes narrowed slightly, covering the edge.

Lu Yifan glanced at Lu Changfeng lightly, and finally turned his head away, "People can't let go yet." ”

"Why?" Liang Fanxin's eyes widened, what stimulated Lu Yifan and aroused his paranoid suspicions.

"There's no reason, let's apply for a search warrant and search Lu Changfeng's home." Lu Yifan didn't even look at Lu Changfeng, shook his hand and went out.

Liang Fanxin glanced back at Lu Changfeng, and chased him out again.

Lu Changfeng was left alone in the interrogation room, watching them leave until the door closed.

"It seems that there is one less Gu Yingying, and another Liang Fanxin is here." Lu Changfeng lowered his head and muttered softly, his voice was so low that it was completely inaudible, and when he raised his head again, it was already a spring breeze, and he said with a smile: "Dear brother, it's really jealous." ”

"Team Lu, did you find something?" Liang Fanxin caught up with Lu Yifan's steps and asked.

Lu Yifan stopped, raised the photo in his hand, and said: "Lu Changfeng's cufflinks are exactly the same as the cufflinks in the photo." ”

Hearing Lu Yifan's words, Liang Fanxin couldn't help but be stunned, what does this mean, it is nothing more than that Lu Changfeng is very likely to be the person that night.

"But Lu Changfeng already has an alibi." Liang Fanxin has been hovering in his heart, Lu Changfeng is a person with an alibi.

"I said, don't trust your judgment too much, after all, we didn't see whether the person in the surveillance was Lu Changfeng or not, did we?" Although Lu Yifan didn't want to make a conclusion about it, now Lu Changfeng's suspicion has increased because of that button.

"Apply for a search warrant immediately, and with this button, we have reason to suspect that he was the murderer who attacked the police that night." Lu Yifan took the photo in his hand on the table.

"Team Lu, wouldn't it be too hasty to make such a decision?" Liang Fanxin frowned, and some disagreed with Lu Yifan's approach.

"We must take any clue seriously, no matter how small the possibility may seem, we can't let it go!" Lu Yifan looked at Liang Fanxin seriously and said to her.

"Well, since you insist on this, then I have nothing to say!" Liang Fanxin knew Lu Yifan's stubborn character, and he couldn't resist him, so he could only obey his orders.

Liang Fanxin applied for a search warrant from above, because Lu Yifan had cracked several big cases one after another, so the people above also trusted Lu Yifan's judgment and happily issued the search warrant.

Liang Fanxin and Lu Yifan got the search warrant and walked directly to Lu Changfeng's interrogation room.

"Now you are no longer assisting in the investigation, but suspecting that you are related to Tian Xue's murder. So you're a suspect now! Lu Yifan walked up to Lu Changfeng with a search warrant and said to him, "Now that the search warrant has come down, we need to search your house, let's go!" ”

Lu Yifan twisted his head and gestured to the monkey. The monkey stepped forward and pulled Lu Changfeng up, and then handcuffed him.

"Brother, do you want me to go to jail so much? Is it because of that incident that you always suspect that I am a murderer? Lu Changfeng looked at Lu Yifan with a sad face, and asked him, "We grew up dependent on each other since childhood, am I this kind of person in your heart?" ”

"I'm doing this now to prove your innocence!" Lu Yifan said unmoved.

So the group of four people thought about Lu Changfeng's house and drove away,

Lu Changfeng's house is in an ordinary community, a rented house after becoming a teacher, not far from the school, but it is not in a prosperous place.

Lu Changfeng walked home, opened the door, and let Lu Yifan and the three of them go in, on the sofa in the living room that he was familiar with.

"The doors of the rest of the places are not closed, so search whatever you want!" Lu Changfeng said calmly.

Lu Changfeng's home is relatively clean and simple, as soon as you enter the door, you will see a huge bookshelf full of books, while the rest of the place is some ordinary furniture, no different from other household furnishings.

Liang Fanxin walked around twice and found that the two-bedroom house rented by Lu Changfeng had nothing in it except books.

"You've been living here since you came home?" Lu Yifan looked around twice and asked Lu Changfeng.

"Brother, I've been thinking about when you can pick up care for me again, but I really didn't expect this to be the case." Lu Changfeng smiled bitterly and said, "I have been working at the school since I came back, and then I rented this house. ”

"Mr. Lu, you studied psychology abroad, why do you still read these books that surgeons read?" Liang Fanxin walked around the bookshelf and found that the books on Lu Changfeng's bookshelf, in addition to some psychology books, actually had many books on surgery, which couldn't help but make Liang Fanxin feel very strange.

"I went abroad for further study and had no income, so I went to the hospital for an internship to earn some salary. Psychology doesn't play a big role in hospitals, so I need to study surgery as well, so that's why I have these books. Lu Changfeng sat down and said lightly.

"Didn't you say you were going abroad for treatment, why did it become further study?" Lu Yifan looked at Lu Changfeng and asked.

"Brother, you don't know the reason why I have depression, do you? As for why I didn't go to the doctor and study, I guess it can be explained that I don't want anyone to come into my heart. Lu Changfeng looked at Lu Yifan and said.

"I always thought I was your closest person, but I really didn't expect that you would give up on me because of an accident, and even disown me as a younger brother! You blamed Gu Yingying's death on me, but you never thought about the harm I suffered because of this accident! My closest brother is still like this to me, how can I make me believe in others! Lu Changfeng's calm narration seemed to hide a violent beast, which made people sound a little chilling.

When Lu Yifan heard Lu Changfeng's words, he was also a little silent for a while.

Monkey and Liang Fanxin saw that the two brothers actually started to confront each other in this situation, both of them touched their noses and looked at each other a little embarrassed: it seems that they should not be here at this time.
