Thinking of Wu Ming, Lin Jia's mind unconsciously returned to the case of the theft of five grams of invisible paint.

Through Cui Luyi's further investigation of Zhang Mingli's father's accidental fall during morning exercise, combined with the surveillance video retrieved by Tan Tan before, it was watched almost frame by frame, and after technical processing, it was accidentally found that before Zhang Mingli's father fell, there was a blurred light point similar to a pebble shot out at high speed from behind a clump of green shrubs, and the target was the oncoming bone of Zhang Mingli's elderly father's left calf. After repeated observations, it was finally confirmed that this should be the root cause of Zhang Mingli's father's fall and cerebral hemorrhage.

Cui Luyi also found a corresponding blue and purple scar as big as a pea on Zhang Mingli's father's left calf on the hospital bed, thus confirming the inference that he fell after being attacked by an unknown person and suffered a sudden cerebral hemorrhage.

It's just that Cui Luyi couldn't find the suspicious person hiding behind the bushes from the bustling crowd of morning exercises.

After all, there are too many people who go to the park for morning exercise every day, old and young, men and women, and there are hundreds of nearly thousands of people in the past. If you want to find that one, you should use a slingshot or other tool to hide behind the green bushes in advance to attack the suspect of Zhang Mingli's father, which is almost an impossible task.

According to Zheng Qingqing's confession, the only person who has contact with him from the outside world is Sui Lizheng in the nursery garden under the Lion Rock. Therefore, as Sui Lizheng did not return from his trip abroad as scheduled, the investigation of the entire case was suddenly interrupted.

Although Wei Chen had already retrieved the consumption records of Sui Lizheng's family of three traveling abroad from the bank, and also found a large amount of money consumption records that did not conform to common sense, Lin Jia, who was beyond the reach of the whip, had nothing to do about it.

Coincidentally, the work of the screen name "Caiyunfei", which Zhao Zengyuan has been investigating, has also fallen into a bottleneck.

At this point, Lin Jia originally had high hopes for several investigations that he hoped to find the hidden traces of "Uncle Sam's Tears", and the investigation of the theft of five grams of invisible paint and the "Caiyunfei" who monitored Zhong Caini's actions came to an impasse, leaving only the suicide of Suo Jianxing and the murder of the young female teacher who were being investigated by the serious crime team.

As for whether to take action against Lu Xidong, who was infiltrated into the Four-Dimensional Research Institute by Niu Tao, a demobilized soldier, Lin Jia is still waiting.

The first is to wait for Lu Xidong to go out to investigate, and it is possible that Zhang Chunhe, who also helped Lu Xidong tamper with the archives for Wang Weidong, has made some progress.

The second is to wait for Lu Xidong to be arrested by his wife Luan Hongjin, and after learning that Wang Weidong has been isolated by the research institute and may have confessed to him, will he jump over the wall in a hurry, so as to risk contacting the organization behind him.

Seeing that the time was already in the early four o'clock in the afternoon, less than three hours before Lu Xidong went to the evening shift, Lin Jia contacted Song Jin again and asked, "Is there a situation?" ”

"Nope. Lu Xidong has not been out since he came home from work in the morning, as he usually did most of the time. ”

Although Lu Xidong's behavior seemed normal, but in a different place, Lin Jia thought that it was impossible for him to remain indifferent at this time. Therefore, out of the cautious habit cultivated over the years, Lin Jia still ordered Wei Chen to lead the members of the action team in advance to assemble in a concealed manner near Lu Xidong's residential community.

And reminded Song Jin and Zhao Zengyuan again: "You must be highly vigilant." I have already ordered Wei Chen and them to go to the vicinity to support you, and if you find an unexpected situation, don't take any risks, you can contact Wei Chen directly. ”

"Understood, Forest Bureau."

As for Lu Xidong, although it has not been fully confirmed that Zhou Wei's car accident case and the planning of Yang Wenjing's murder case are all from him, Lin Jia has always maintained a high degree of vigilance against him. Because, whether it is the confession of Shi Xiaoyu, junior high school, Qian Cuihong and others, or the confession of his wife Luan Hongjin, it is enough to show that he is an extremely dangerous person.

Time passed quickly, seeing that it was already half past seven in the evening, and it was past Lu Xidong's shift handover time, but the other party still did not move. This anomaly basically confirmed Lin Jia's judgment that Lu Xidong might take action this evening.

Just wanted to remind Song Jin and Zhao Zengyuan again, but Tan Tan suddenly knocked on the door and walked in.

"Forestry Bureau, listening to the signal of Dr. Zhong's mobile phone has reappeared. and the mobile phone number that used to log in to the network with the screen name of 'Caiyunfei' was also turned on. ”

"Can you detect the approximate location of the two signals?"

"The signal from Dr. Chung's cell phone cannot determine the approximate location. However, another mobile phone number can be measured, and it is still within a kilometer radius of the four-dimensional research institute. ”

"Where is Dr. Chung's phone?"

"At the institute."

"Okay, keep watching. Report as soon as there is a new situation. ”

"Yes."

Lin Jia, who watched Tan Tan leave, couldn't help but be suspicious of this sudden situation.

Why didn't it appear late or early, but when Lu Xidong was acting abnormally, he listened to the signal of Zhong Caini's mobile phone, and the mobile phone signal that "Caiyunfei" used to log in to the network appeared at the same time?

If there is no relationship between the two, but pure coincidence, Lin Jia can't convince himself no matter what.

Are they trying to distract the police so that they can provide cover for Lu Xidong's upcoming actions?

If there is some kind of correlation between the two, is there anything else possible?

After thinking about it, she found that there were only Cui Luyi and Tan Tan under her subordinates, and Tan Tan couldn't leave her job for a while, so Lin Jia had to call Ling Zhan again. Because, she really can't spare the manpower to track and listen to Zhong Caini's mobile phone and the two signals of the mobile phone that "Cai Yunfei" used to log in to the network.

"Team Ling, I'm really embarrassed, I have to ask for your help again."

In fact, there was no need for Lin Jia to explain, as soon as Ling Zhan received the call, he knew in his heart that the other party must have something very important to call at this time, so he didn't ask anything, and said directly: "Forest Bureau, please instruct." ”

"Can you ask Team Ling to transfer the criminal police team to the vicinity of Lu Xidong's residential community to replace Xia Zengyuan, Wei Chen and others?"

"No problem. May I ask the Forestry Bureau, who will the criminal police team contact when they arrive? ”

"Just contact Wei Chen or Song Jin directly, and I'll notify them immediately."

"Okay, I'll lead the team over personally."

"Thank you."

Putting down the phone, Lin Jia quickly told Song Jin, Zhao Zengyuan and Wei Chen about the situation through the walkie-talkie. Finally, he said to Zhao Zengyuan: "After the city bureau passes, you take Wei Chen and the others to the vicinity of the Four-Dimensional Research Institute to meet Cui Luyi, I don't need to say more about what to do, right?" ”

"Yes, Forest Bureau."

After all, it was Zhao Zengyuan who had been in charge of investigating "Caiyunfei", so Lin Jia would replace him with him.

Fifteen minutes later, Zhao Zengyuan's report came from the walkie-talkie, and they who were replaced by Ling Zhan had already joined Cui Luyi near the Four-Dimensional Research Institute. Lin Jia also left the office and came to Tan Tan's technical investigation department, which was responsible for listening to the two signals.

"Is there anything out of the ordinary?"

"Nope. The telephone signal used by the 'Caiyunfei' always wandered within a kilometer of the Four-Dimensional Research Institute. ”

"You mean they're always moving?"

"Yes. And it's more like going around the four-dimensional research institute in circles. ”
