More than a month ago, Gu Song obtained a piece of grapevine from Shen Hang: in addition to the underground prison, the R&D organization seems to have another secret base. They bought abducted children around the age of three or four from a trafficker gang in Yunnan Province in the name of organ trafficking, but in fact they were the subject of the organization's research.

At that time, Gu Song thought that the secret base that Shen Hang was talking about was the one that Qin Yu told him. In order to find the organization's hiding place as soon as possible, Gu Song ignored the clues provided by Shen Hang, but directly asked Teacher Chang to hypnosis for him, retrieved the coordinates left by Qin Yu, and thus discovered the No. 2 Research Institute hidden in the depths of Liangshan.

However, things did not turn out the way he expected. Research Institute 2 is only a backup base, and the test subjects are still the same inmates who failed to escape from the underground prison, and have no connection with children. From this point of view, the information provided by Shen Hang should have another meaning.

Through his conversations with Dr. Xue, Gu Song believes that the Children's Institute may be real. The question is where is that institute hiding? What is the scale? Are you still using it? How can I find it?

Whether it was the underground prison before or the No. 2 Research Institute, it was because of the coordinates given by Qin Yu that they could accurately find the location of the research base. Now, they only have a little unclear clue provided by Shen Hang, and how to complete the next task is a headache to think about.

On the way back to the city bureau, Gu Song told Xia Shi all these things truthfully, and pointed out that if he wanted to find more clues, he might have to go to Yunnan in person, and maybe he would have to deal with local drug dealers. According to Shen Hang, the middleman who sold the child to the organization was imprisoned in a certain prison for drug trafficking.

Listening to Gu Song's explanation, Xia Shi felt that things were becoming more and more outrageous. Not long ago, he naively thought that as long as the organization was hidden in the Daliang Mountain, their task would be successfully completed. Even if there are doubts that the organization may have other research bases, there is no evidence, and everything is just speculation. But through the conversation just now, even he had to believe that they had an even more difficult journey to go on the road to destroying the organization.

Half an hour later, the two of them acted separately in the parking lot, and Gu Song returned to the task force to continue investigating the murder and robbery case with a gun, but Xia Shi did not start work immediately. With his understanding of Gu Song over the years, that guy would definitely not be honestly at the mercy of Shen Hang, and it was impossible that he had not come up with any strategy to deal with Shen Hang.

Now that Gu Song has clearly expressed his attitude, he resolutely does not use fake antidotes to trade with Shen Hang. In order to seize the opportunity, he will definitely make other small moves in private, maybe he will bypass the police's sight, contact Shen Hang in private, reset the trading chips and trading methods, and use abnormal means to lure out Shen Hang and rescue the hostages. In this way, Gu Song would put himself in a very dangerous situation.

Xia Shi recalled that he saw Gu Song coming out of the technical department uneasily last night, and seemed to be thinking about a very important matter. Judging by his intuition, that incident might have something to do with Shen Hang. As a friend, and at the same time as a police officer, he can't let Gu Song take risks alone, and he doesn't allow Gu Song to do anything stupid that is outside the law.

Thinking of this, Xia Shi decided to investigate Gu Song secretly. In any case, he had to prevent a catastrophe before Gu Song could take action.

In the past few days when Gu Song has been absent-minded, the investigation work of the special case team has made a breakthrough. Combined with the armed robbery case that occurred in Yichang City, Hubei Province at the end of 2014, the police expanded the scope of the investigation, and conducted a comprehensive and detailed investigation of the people released from prison who met the characteristics of the crime in recent years, and came up with a list of suspects who seem to be more reliable at present.

There are seven people on the list, three of whom are registered in Chongqing, and the other four have lived in the Chongqing area for a long time and speak authentic Chongqing accents. Among the suspects, two of them were sentenced to prison for gun-related cases, and the other five were arrested by the police for varying degrees of violence, robbery and other cases.

After a multi-faceted analysis, the police found that Huang, who had been sentenced to prison for illegal possession of firearms in March 2011 and released in April 2014, was suspected of committing a major crime. This person was born in Shapingba District, Chongqing in 1980, is 173cm tall, high Chinese, irritable and irritable, and was dealt with by the police once in the early years because of violent wounding cases.

(According to the video data that has been collected, the police found that Huang's gait characteristics are highly similar to those of the serial shooters in R City.) Although this analysis cannot be used as direct evidence, it indicates the direction of the police investigation to a certain extent. ）

In addition, considering that there is a special survivor in the "6.7 shooting" (who has the ability to never forget), the police have obtained the audio materials of the suspect from many sources, hoping that He Weiqi can identify the murderer who appeared in the convenience store on the night of June 7, and provide more basis for the police to solve the case.

"Gu Song, you came back just in time." As soon as he walked into the office, Qiao Sheng hurriedly stopped him and explained, "We have already contacted He Weiqi's mother, and she will bring He Weiqi to the bureau to cooperate with us in the identification work, you just go to assist." ”

"Why did you let me go?" Gu Song frowned unhappily, and his indifferent attitude surprised Qiao Sheng. "What's the matter, aren't you interested in that boy? And through the recent contact, he also trusts you very much. Having you by his side can take away his nervousness. ”

"I'm afraid not anymore." Gu Song smiled bitterly twice and said, "I think it's better for me not to appear in front of him." If you are really worried about He Weiqi's emotional condition, then bring Teacher Chang here. Wouldn't it be more reassuring to have a professional and responsible counsellor present than me, a layman? After speaking, Gu Song took a step towards the desk inside, but Qiao Sheng grabbed his clothes and asked suspiciously, "What do you mean by this?" ”

"It's not interesting. I still have a lot of work on my hands and I don't want to waste my time on something that doesn't make sense. ”

"How could it not be meaningful? He Weiqi's testimony can provide us with clearer clues to solve the case, isn't it you who chose to believe him in the first place? ”

"I still believe in him."

"Then why are you ......?"

"Team Joe." Gu Song was afraid that Qiao Sheng would be cranky, so he reluctantly squeezed out a smile and said, "Don't think too much, I just had a little conflict with that kid, and it's still in the Cold War period." It's okay if he doesn't see me, but when he sees it, his mood gets bad. ”

"What's wrong with you?" Qiao Sheng was a little surprised, he didn't expect Gu Song to be as knowledgeable as a child.

"Actually, it's nothing." Gu Song didn't want anyone to know that He Weiqi was related to Miss M for the time being, so he shrugged his shoulders helplessly and continued to perfunctorily, "You know, that boy's temper has always been very weird. The so-called words are not speculative for more than half a sentence, I accidentally him off, and the matter is as simple as that. ”
