Xia Hongyun was flustered and had no master of the six gods, if something happened to Qin Kai, she really didn't know what to do. If anyone can deal with the murderer, then only Qin Kai.

"Don't come here!" Qin Kai roared, his eyes were red, and he only felt a strange gas enter his body, flowing everywhere, stirring his breath unsmooth, and his chest was uncomfortable.

He slowly mobilized the Yin and Yang Origin Qi, and after a while, he forced this gas out of his body. Sisi, like the sound of water vapor evaporating, Qin Kai's body was full of water vapor, shrouded in a layer of fog, and it took half a day for this water vapor mist to disappear.

"Qin Kai......" Xia Hongyun rushed over, grabbed Qin Kai's arm, looked at Qin Kai with a nervous expression, and asked, "How are you?" Don't scare me!"

Qin Kai shook his head and said, "I'm fine." Just now, he wanted to save Gong Chenggong, and suddenly heard a harsh and ugly music in his ears, and the power exuded by this music was many times stronger than I didn't know just now.

Qin Kai understood that it was the secret murderer who was attacking him and prevented him from saving Gong Chenggong, so he could only watch Gong Chenggong jump in front of his eyes.

At this moment, a burst of melodious music came from nowhere, and Xia Hongyun exclaimed: "Hurry up and shoot your ears, don't even listen to yourself if you become deaf!"

Xia Hongyun raised the gun, and then Qin Kai said, "Wait a minute! This voice is not what I just heard." ”

Xia Hongyun listened to it for a while, it was indeed another tune, and she was puzzled, and asked Qin Kai: "What is he blowing this tune for?

Qin Kai sneered and said, "He's warning us, don't meddle in our affairs, we won't be so lucky next time." ”

"Does he have a grudge against Gong Chenggong? Xia Hongyun frowned and said.

"The first policeman to die was Shang Tieniu, the second was Deputy Director Gu, the third was Zhang Yao, and the fourth was Gong Chenggong. Qin Kai took a piece of paper, carefully recalled the case information he had read before and the information Xia Hongyun had investigated, and said while drawing, "If Shang Tieniu, Deputy Director Gu, and Zhang Yao are members of Ying Feifei's task force, then Gong Chenggong is not the constituent of Ying Feifei's project, and even he has not participated in the arrest of Ying Feifei. ”

Xia Hongyun said: "In this way, the murderer is indeed not Ye Qingyu, but someone else. Judging from his modus operandi, first, he understands the police's procedures, and second, he has a huge grudge and dissatisfaction with the deceased, and he is taking revenge. But what do the four have in common?"

As long as you grasp the common ground, you can investigate the murderer.

But these four people have no intersection at all, from their work history, and the relevance of the cases detected, there is no common intersection. The murderer wants revenge, and it is easy to understand that he is targeting one of them, or several people who have a common intersection can also be understood, so why should he target four unrelated people?

Moreover, judging from the murderer's revenge, he still has the object of revenge, and he has no intention of stopping.

Lin Tinghua said angrily: "The murderer is simply murderous, he is retaliating against our police, the nature is even worse, and he must not be spared." ”

Qin Kai had been meditating with his eyes closed, not saying a word, as if he hadn't heard everyone's speculation and indignation.

"Qin Kai, did you think of something?" Xia Hongyun asked.

Qin Kai shook his head and said, "It's not mature enough, let me think about it." Also, immediately block the police station, the murderer should still be in the police station. ”

Everyone dispersed in an uproar and searched everywhere, Qin Kai and Xia Hongyun came to a nearby street, because it was late at night, there were few pedestrians on the street.

Xia Hongyun ran back and asked the janitor, and said, "Uncle, did you see anyone leaving the police station just now?"

The uncle said: "I drove a police car, it seems that there is an emergency police, so I didn't ask more, let the car go." ”

"Could it be that the murderer left in a police car?" Xia Hongyun was furious and called the reporting center to ask if she had received a call today.

The person in charge of the reporting center said yes, and someone has been sent to deal with it.

Xia Hongyun hung up the phone, her brows were tightly wrinkled together, the police car left in a hurry to deal with emergencies, not that the murderer left in a police car, that is to say, either the murderer was still in the city bureau, or the murderer left the city bureau through other channels.

She was not at ease, so she went to the information center to call up the cameras in every corner of the city bureau, and found that there were several cameras that were broken, which were blind spots, except for this one, everything else was normal.

"How could this be? Could it be that the murderer was already hiding in the city bureau?" Xia Hongyun was puzzled, the cameras in several important places such as the gate and the office building were not broken, no matter where the murderer came in, it was impossible for him to be silent, so that people could not find a trace.

Back in the conference room, Xia Hongyun still couldn't figure it out, Qin opened his fingers and tapped on the tabletop, and said: "If the murderer came in with someone you are familiar with, or if the murderer is someone you are familiar with, then even if you see him on the camera, you may not be able to see which one is the murderer." ”

Xia Hongyun's eyes lit up and said, "Yes, why didn't I think of it? If the murderer is known to us, even if we see him, we may not recognize him." With this clue, she hurriedly arranged it and checked all the people who came and went today, and made sure to lock up the suspect.

was busy until late at night, and the policemen who went out to touch the platoon all came back, and they all shook their heads at Xia Hongyun, saying that they had found nothing. Xia Hongyun was disappointed for a while, and even Qin Kai frowned, as if he had quickly missed something, and his mind was confused.

Lin Tinghua invited everyone to have supper, everyone was eating, Xia Hongyun suddenly remembered that Lin Tinghua and Deputy Director Gu entered the city bureau at the same time, perhaps, Lin Tinghua would know something.

Xia Hongyun asked: "Director Lin, you and Deputy Director Gu entered the city bureau at the same time, you have worked together for more than 20 years, what do you know about Deputy Director Gu?"

Lin Tinghua thought for a while and said: "Although we have worked together for more than 20 years, we don't know each other very well, and we don't have much intersection with each other. Hey, if you want to say that Deputy Director Gu has any lace news, it has to be more than ten years ago. I heard that Deputy Director Gu and a lady sitting on the stage got along, and the two loved each other very much, but in the end, Deputy Director Gu had to break up with that young lady due to external pressure. This matter has always been a stain on Deputy Director Gu, so that he has never been able to be the director. Otherwise, he would probably be the director of the bureau, or even the deputy director of the provincial department. ”

"Miss Sitting on the Stage!!" Qin Kai's eyes lit up, he suddenly remembered that in the case materials he had read, it seemed that this matter was also mentioned, he immediately pushed away a bunch of materials, found those materials, looked at them for a long time, his frowning brows stretched out, and muttered: "I see!"
