No matter what, Wang Wei's suspicion has not been cleared.

At this moment, Hu Zhao from Team Three is ordered to monitor Wang Wei's every move. Any slight movement will be reported to Li Xiang immediately.

Meanwhile, Team Two's side is rather quiet. After Qiu Chengguang left work, they had been hiding in the shadows to protect him, but found nothing unusual.

It wasn't until Qiu Chengguang got home that Team Two and Team Three joined forces.

At this time, the suspect had already returned to the hotel without any other movement.

Upon receiving the onsite intelligence, Li Xiang decided to let one of the teams go back to rest.

The distance between Qiu Chengguang's home and Longxin Hotel is very short, so leaving one team there to watch is also manageable.

Now he is short-handed, and every personnel must be used precisely.

At this time, they still didn't have enough evidence to prove that Wang Wei is the killer, so they dared not alert him. If the arrest operation alarmed the real killer, it would be all for nothing. Therefore, they need to observe more of Wang Wei's actions to see if he is making other preparations for murdering Qiu Chengguang.

As long as they can prove that he is indeed intentionally approaching Qiu Chengguang, the police will arrest him immediately.

The next day,

Hu Zhao from Team Three came over to hand over the work to Ding Lifan from Team Two; everything was normal last night.

And after Ding Lifan escorted Qiu Chengguang to work, they could go back to rest.

During the period, Ding Lifan also asked Qiu Chengguang if he knew Wang Wei, and the other party denied even knowing this person.

The management of foreign-invested enterprises is still very strict. Strangers without an appointment and reception cannot enter the factory.

Therefore, Qiu Chengguang is very safe at work, and Team Two can go back to rest. Then they will come to escort him home on time after work and then switch shifts with Team Three.

Such shift work reasonably utilizes limited police resources.

After going to work, Li Xiang also sought out Su Jiayi to understand the situation of Qiu Chengguang's wife.

"We have met with Qiu Chengguang's wife, her name is Pan Min. She currently works in a state-owned enterprise, and her job is stable. Upon understanding, she also indicated that they hadn't offended anyone. This is unusual, both husband and wife have no enemies, so who wants Qiu Chengguang dead? So I looked at the insurance on Qiu Chengguang."

"Are you suspecting Pan Min of murder for insurance fraud?"

Li Xiang understood Su Jiayi's purpose. His first case was about murder for insurance fraud. This is also an important motive for committing a crime. If Pan Min purchased large accident insurance for Qiu Chengguang beforehand, then there is motive.

"Initially, I thought so, but after checking with the insurance company, he doesn't have a large insurance policy."

"Then it might not be her."

Li Xiang breathed a sigh of relief, they still need to trust the marital relationship.

However, what Su Jiayi said next made Li Xiang nervous again.

"But when I was questioning Pan Min, I always felt something was wrong with her. This is just my intuition, currently without evidence to support it."

Su Jiayi, a seasoned detective, still values her intuition very much. Pan Min gave her a feeling that she couldn't describe.

"What do you plan to do?"

Li Xiang respected Su Jiayi's opinion and was prepared to hear her thoughts.

"Today, I plan to go to her workplace to learn more about her social circle."

"That's good."

Only a comprehensive understanding can determine whether a person is suspicious.

"Have you found anything on your end?"

"Currently, there is one person who is rather suspicious, and Team Three is keeping a close watch on him."

Li Xiang also communicated his situation with Su Jiayi, hoping for her input.

"I think this person is indeed very suspicious. As for your doubt, the killer might be a foreigner, which I find unlikely. Given the current domestic security situation, it's not easy for a killer to come in, but just to be safe, your decision is correct. Continuing observation for a period is necessary!"

Su Jiayi affirmed Li Xiang's thoughts, suggesting it's still inappropriate to alert the suspect before the case is clear.

While Su Jiayi went to investigate the situation at Pan Min's company, Li Xiang once again found Mao Ji, who was in charge of liaising with the cyber police, to understand the situation there.

"Currently, there is no progress in the investigation against the dark web. The dark web's server is overseas, making it challenging for us to investigate, but the cyber police won't give up. They have precedent in destroying the dark web; it just takes time."

Some things can't be rushed. Not every case can be solved in the shortest possible time. Most cases might drag on for a year or two, or even a decade, before a breakthrough occurs.

Especially with cybercrime, it usually takes several months of effort by the cyber police to locate the real position of criminals through the internet before deploying police forces to arrest them.

Expecting a result after just two days is indeed difficult.

"Alright, continue to follow up!"

What can Li Xiang say? He himself is not a super hacker. If he were, dealing with illegal criminals on the dark web wouldn't be a problem.

For now, the only thing Li Xiang can do is continue to follow the lead on Wang Wei.

So, he and Sun Zhidong went to Longxin Hotel again to meet up with Hu Zhao and Team Three.
