"The murderer has a mixture of love and hate for Kong Xiaotong, so after killing her, he also put the roses well before leaving, but Li Yinliu is different, the murderer's hatred for her is obviously far more than love, and even not love, leaving the roses may be just perfunctory, and it may be just to achieve a unity with the first murder case, so it has to be released, so it will naturally be more perfunctory. Right? Tang Guo asked.

Qin Cang nodded: "The murderer was able to choose Kong Xiaotong and Li Yinliu, which means that there is something in common that allows the murderer to connect Kong Xiaotong and Li Yinliu, two characters who look very different, as for what this common point is, we haven't found it yet, so let's not mention it for the time being." As you just said, the two female deceased were chosen by the murderer to be his victims, but there is a certain difference in his attitude towards these two people, what does this mean? It shows that he did not treat Kong Xiaotong and Li Yinliu equally. For the murderer, these two people have both something in common and obvious differences, the commonality makes the two of them, who are completely different in our opinion, become victims of the murderer, and the difference makes these two people who are considered by the murderer to have obvious commonalities are actually different, Kong Xiaotong is obviously better than Li Yinliu emotionally. ”

Tang Guo was a little cloudy and foggy by what Qin Cang said, listening to his words was like a tongue twister, she knew that Qin Cang wanted to express a certain meaning, or it was better to say that when he was saying these words, he was actually thinking about some unformed thoughts in his heart, it seemed that he should have a little idea, but it was not mature enough, or there was something that had not been sorted out and smooth, so he went around and around, while analyzing the situation in front of him, he was still trying to smooth out his thoughts.

"Looks can be ruled out, and personality can also be ruled out," Tang Guo was also a little confused, "I really can't think of what kind of intersection between these two people can make the murderer associate them together, let alone directly compare the two of them together, even if I want to find any similarities from their bodies to generalize a specific group of people with certain characteristics other than the two of them, I can't find it!" ”

After she finished saying this, she suddenly found that Qin Cang was staring at herself, which made her suddenly feel a little at a loss, and hurriedly looked down at herself, and quickly checked if there was anything wrong with her body, and confirmed that there was no problem, so she asked in wonder: "Why are you looking at me like that?" ”

"Look at the time when a blind cat touches a dead mouse!" Qin Cang seemed a little excited, "You're right, it's not necessarily that there is any direct similarity between Kong Xiaotong and Li Yinliu, but it is possible that in the eyes of the murderer, they both have certain qualities, which can make the murderer think of another group, or a certain individual, so that it indirectly constitutes the common ground between Kong Xiaotong and Li Yinliu." ”

"So what do you think is the trait in the two of them that can be summed up and associated with a specific group?" When Tang Guo heard this, he also felt a little excited, and hurriedly opened his mouth to ask Qin Cang's opinion.

Unexpectedly, Qin Cang shrugged: "I don't know, I'm just inspired by you and have a direction of thinking." ”

Although this answer is somewhat disappointing, Tang Guo can also see that Qin Cang is smart and smart, but he is not an all-knowing and all-powerful immortal after all, and it is very normal to have no way to determine it all of a sudden, just like he said, it is a good thing to have a direction of thinking, I believe that he should rely on such a direction to quickly put the whole idea of solving the case on the right track, and dig out the truth as soon as possible.

In the next two days, Qin Cang and Tang Guo only did two things in general, the first thing was to go around the community where Kong Xiaotong and Li Yinliu's house were located from time to time, enhance the effect, and render the atmosphere, many uncles and aunts in that community recognized the two of them, so basically they didn't need to talk to people everywhere on purpose, just walk around the community, turn around, and someone would quickly notice them, and then whispered that the police were coming again, I'm sure I'm here to investigate who's who.

And Yan Lifu and Xiao Zhu, the two people who coincide with Qin Cang, seem to be doing similar things, so the two groups of four people are like a succession, and they will meet by chance in the community at every turn, Qin Cang still has nothing to say every time, Yan Lifu is still a good demeanor and takes the initiative to say hello, and the rest is Tang Guo, who is a little helpless, and Xiao Zhu, who is getting more and more dazed, Xiao Zhu seems to be a little strange, they are investigating Tang Tianlu, but it seems that they are not really doing any substantive investigation, Qin Cang kept saying that they doubted Shi Liquan, but the result was the same, wouldn't it be too strange?

Tang Guo originally didn't believe Qin Cang's guess, thinking that he used colored glasses to see people, so he looked at people narrowly, but in the past two days, seeing that the doubts in Xiao Zhu's eyes were getting deeper and deeper, she had some faith in Qin Cang's analysis and judgment before, and felt that Yan Lifu might really have reservations and didn't tell Xiao Zhu his true intentions.

The second thing Tang Guo and Qin Cang did in the past two days was to look around for Kong Xiaotong and Li Yinliu's relatives and friends, and ask them about these two people, including personality, including how they behave on weekdays, and even including their clothing, life details, etc., Qin Cang chatted with everyone very seriously, summarized the characteristics they described, and finally summarized them together for comparison.

At the same time, the community that has had two incidents has finally strengthened the management measures for security protection under the strong request of the owners, it can be said that the community has a little meaning that everyone is in danger, all the residents, even if they are not the same age as Kong Xiaotong and Li Yinliu, even if they are not young mothers who are married or even have children, even if they are the men in the community, everyone's nerves are tightly collapsed, Qin Cang is quite satisfied with this, according to his words, to such an extent, It should be enough to startle the snake, and maintain such vigilance, at least it can ensure that the murderer wants to attack the people in the community again, I am afraid it will not be too easy, it is difficult to find the time for insurance and people who have no sense of prevention.

On the night of the third day, everything was still very normal, until the early morning of the fourth day, when a rapid mobile phone ringtone woke Tang Guo from her sleep, her brain had not fully awakened, her consciousness had already reacted instinctively, and an ominous premonition suddenly woke her up completely.

"Hey! I'm Tang Guo......" Tang Guo grabbed his phone and hurriedly answered it.

"Go downstairs in five minutes, I'll pick you up, there's a situation." Qin Cang's voice came out of the earpiece.

"Oh, okay, I'll get up!" Tang Guo hurriedly agreed, threw the phone aside, jumped out of bed to change clothes as quickly as possible, now the weather is getting colder and colder, in the second half of the night, she climbed out of the hot warm quilt, she was a little shivering from the cold, no matter how warm the clothes looked, they were put on her body as if they had just been salvaged from the ice cave, not to mention how cold it was, and her upper and lower teeth chattered.

Wait a minute...... What Qin Cang said was that he would come and pick him up when he went downstairs in five minutes? Don't you usually pick him up by yourself? What does it mean that he came to pick himself up? Did it mean that he came to look for him first, and then they drove to the scene of the crime? Tang Guo guessed a little, got dressed, wrapped a thick coat, and didn't forget to take the key to his little scooter when he went out, and then left a note for Tang's father and Tang's mother and crept out of the door. Although it is said that this is for work, even if Tang's father and Tang's mother know, they will naturally not stop Tang Guo from leaving, but in this way, they will inevitably worry about themselves, Tang Guo is unwilling to let them worry, and would rather sneak out of the door quietly like a thief.

After going downstairs, Tang Guo was still going to wait for Qin Cang at the gate, but as soon as she walked out of the door, she saw a white SUV parked on the side of the road flashing its lights towards her, she was still a little puzzled, stopped and looked at the car, and the car flashed its lights at herself.

Looks like it's really calling for yourself. Tang Guo is sure this time, at the middle of the night, how many people will run out at this time for no reason. So Tang Guo walked towards the SUV with a trace of doubt, walked to the car, and lowered the window of the cab, revealing Qin Cang's face.

"Get in the car, there's a case." He tilted his head in the direction of the co-pilot and motioned for Tang Guo to sit in.

Tang Guo hurriedly went around and got into the car, the warm air in the car was very full, and most of the cold air around her body was blown away at once, she rubbed her hands, fastened her seat belt for herself, and then made time to ask Qin Cang: "Where are we going?" What happened? Whose car does this belong to? Do you know how to drive? ”

"First, let's go to the riverside." Qin Cang started the car and drove to the gate of Tang Guo's community, "Second, a female corpse was found by the river, it is said that the same body was stabbed several times, and a rose was thrown beside her, so it should be that we need to be responsible, so we will be notified to go to the scene." Thirdly, the car is mine. Fourth, I do know how to drive. Do you have any other questions? If so, just ask them all in one go. ”

"You can drive, and you have a car!" Tang Guo was a little surprised, "Then why did you always take my car before?" You've asked me to drive over to pick you up every time before, my car is so small, what are you trying to do? You're really unkind, you have a car, and you can drive, you didn't say a word, you never told me! ”

"Riding in your car is to save worry and trouble, I didn't say because you didn't ask." Qin Cang said innocently.

"Then why don't you just keep it up? How nice it would be to call me to pick you up in a car. Tang Guo pouted, he didn't expect Qin Cang, such an awkward and arrogant guy, to have such a naïve side.

Qin Cang glanced at her: "I'm not so graceful that I don't have that kind of grace, in order to save a little effort for myself, I asked a woman to drive to pick me up in the middle of the night." But take my car in three chapters of the offer law. ”

"Oh, then you say, I'll do what I can." Tang Guo nodded.

"First, you are not allowed to eat in my car. Second, I am not allowed to drink anything in my car that leaves traces. Qin Cang made his request very quickly.

"Do you have a habit of cleanliness?" Tang Guo asked instinctively, and immediately received a roll of Qin Cang's eyes, she hurriedly nodded knowingly, "Okay, no problem." Isn't that the third chapter of the covenant, and what is the third point? ”

"I haven't thought about it yet, I'll tell you when I think about it." Qin Cang replied.

Tang Guo didn't know what to say, looked at him, pouted, and didn't respond.

The white SUV drove into the night and drove towards the scene of the crime.
