Looking at the display screen, Liu Zhiqin suddenly said, "The letter was sent on May 4, 5 years ago, but I remember..."

Hua Chong immediately realized, "Tang Su's Weibo account was only registered in December four years ago!"

Liu Zhiqin half-closed his eyes, "Two possibilities. First, this 'A Celery' is someone Tang Su knew in real life. Second, Tang Su once had a Weibo, 'A Celery' was a person she posted on." A friend on Weibo."

"The first possibility is ruled out." Hua Chong said, "If this person knew Tang Su in real life, we would have found out a long time ago."

"That means Tang Su once had a Weibo."

"Can you find out?"

Liu Zhiqin's expression froze slightly, and he tapped Tang Su's laptop with his index finger, "This computer is a new product from last year. I have seen the traces on the Internet, and she has never logged in to an account other than 'Da Tang Xiao Su'. I think To find this number, there are three ways left, one is to find her on a computer, the other is to go to her company and her parents’ computer to try their luck, and the third is to find someone who knows her other Weibo.”

"How about contacting the company?"

"The real-name system was not implemented four years ago."

Hua Chong took a deep breath, "I'll arrange staff right away."

Liu Zhiqin nodded, "Flower team."

"what?"

"Now I think this 'a piece of celery' is very suspicious. The murderer is very smart. Assuming that 'a piece of celery' is the murderer, there is no doubt that 'he' took advantage of Tang Su's change of Weibo midway to hide himself in the Behind the network. We only know that 'he' sent a postcard to Tang Su, but it is difficult to find out who is behind these four words. 'He' seems to have a certain understanding of network security, maybe very well. Two At the scene of the murder, the mobile phone was lost, there must be some information in it that 'he' can't let us know."

Hua Chong seemed to be thinking, and said slowly: "Once we know, we can follow the clues and find 'him' from the Internet."

"Yes!"

"The phone can't be traced. The murderer should have disposed of the phone immediately after the incident." Hua Chong raised his eyes: "You are an expert in the Internet. What do you think is left in the phone?"

"Call records can be excluded, which can be checked without finding the mobile phone. The same is true for the public's real-name social network. If I were a murderer, I would plant a virus in the victim's mobile phone through the wireless network, or build a small mobile phone that can send messages. The local area network, or it only plays the role of monitoring the victim." Liu Zhiqin looked at Hua Chong after finishing speaking, and explained: "This is not a profound thing, anyone who has a certain understanding of network security can do it."

Hua Chong walked around the desk twice, "If it's surveillance, this can explain a problem - Tang Su and Xu Yujiao's normal life route does not include Daoqiao Road, and Daoqiao Road lacks surveillance, two kilometers away The archaeological base is even more desolate. The murderer commits crimes in these two places, and the risk is much smaller than in other places. As soon as Tang Su and Xu Yujiao arrived in this area, 'he' just appeared, and 'he' knew their whereabouts .”

"Why did Xu Yujiao appear on Daoqiao Road? Sanghai has already mentioned the reason." Liu Zhiqin said, "But why Tang Su went to the archaeological base on January 1th, I don't understand."

"Although she doesn't like history like Xu Yujiao, she must also be interested in history and archeology." Hua Chong said: "Otherwise, it would be impossible to put the postcard of Beiman Mountain on the desk."

"Hidden history buffs?"

"you can say it this way."

"But the archaeological team started excavating after the Spring Festival. Even if Tang Su is interested in history, he shouldn't go there on January 1. There was no one there at that time. What does she want to dig out in advance?"

"Don't forget, the tomb was not discovered just now. Since industry experts know about it, it's not surprising that history buffs know about it." Hua Chong said, "But I'm curious about what Tang Su wanted to do there. She suddenly thought Go, someone deliberately guides you.”

"If someone deliberately guided it, then my guess just now is very reasonable." Liu Zhiqin smiled, "Building a small local area network by planting viruses, leaving a message in Tang Su's mobile phone, we can't trace this information, unless Tang Su's cell phone is found."

Hua Chong said in a low voice: "That's why 'he' has to dispose of the phone..."

"I'll do my best to investigate." Liu Zhiqin's tone softened, with a smile on his face, "We will definitely be able to solve the case."

"Wait!" Hua Chong raised his hand, "I thought of another possibility."

"Ok?"

"Your assumption of 'building a local area network' just now is theoretically true, and it's easy for you, but what about the murderer?"

Liu Zhiqin raised his chin slightly, thoughtful.

Hua Chong shook his head slightly, "Brother Xiaoliu, you may have overestimated the murderer. 'He' may not be able to build that local area network as easily as you. Taking a step back, if 'he' really built it, why should Tang Su build it?" Believe the information "he" left in the phone out of thin air, and be lured by "him" to rush to the scene of the crime? When ordinary people see the "suspicious information" in the phone, isn't the normal reaction to ask the people around them? Even if it is not the case , Will you also 'Baidu it'? But Tang Su didn't."

Liu Zhiqin was silent for half a minute, his frowning relaxed, obviously convinced, "I think about the problem from my professional point of view, and I really think too far. That's right, just relying on the information that appeared on the phone inexplicably It is illogical to fall into the trap of a murderer. Flower Team, is there another possibility you want to talk about—a niche, non-real-name social networking site?"

"Yes!" Hua Chong said: "It may be a niche program for exchanging history, and it is only for browsing on mobile devices. Therefore, we found no browsing traces on the computers of Tang Su and Xu Yujiao. The murderer took their mobile phones, it may be the Because 'he' did something to guide Tang and Xu above, 'he' can't let us discover this!"

Liu Zhiqin propped his forehead, "If this 'stronghold' exists, then someone must know about it."

"I have already confessed to me about the discovery of the female corpse, and I have not concealed it at all." Lu Yang was tall and thin, but carried his back on his back, his eyes were half covered by his forehead, his hands were twisted together, and he looked very nervous.

But the tension is not surprising.

"I invite you to come here today, because I want to know another thing from you." Hua Chong said, "I heard that you like history very much, and your ambition is to engage in archaeology?"

Lu Yang's eyes lit up, he looked up at Hua Chong, his lips pursed slightly - it was the instinctive reaction of young people when they heard something they were interested in.

But his excitement didn't last long, and the brilliance in his eyes gradually dimmed.

"I like it, but my parents said that studying history is useless, archeology is hard work and you can't make money, and dealing with dead people is also bad..." Lu Yang said in a low voice: "They don't allow me to study history, they want to send me abroad to study finance."

"But you don't seem to give up?" Liu Zhiqin asked.

Lu Yang was apprehensive and proud, and raised his voice, "Mm! Whenever I have time, I will go to the base to study with Brother Chen and the others!"

Hua Chong and Liu Zhiqin glanced at each other, and the brother Chen that Lu Yang was talking about should be a staff member of the archaeological base.

"They taught me a lot, which was much more useful than going to the library and reading materials on the Internet alone." When it came to archaeology, Lu Yang began to eloquently.

"Online?" Hua Chong asked, "What kind of websites do you usually use? Are they all about history?"

"Of course! I never waste my time on irrelevant entertainment. I am different from those who advocate enjoying life. I am also different from my parents. I..."

Hua Chong interrupted, "What are the specific ones? I want to know more."

Lu Yang was startled, "You also like history?"

"Not as proficient as you." Hua Chong liked it, "But I'm really interested."

Lu Yang hastily contributed his own treasure website, and every time he said one, he also gave a large introduction about the website.

"Is there only these?" Hua Chong wrote down the names of the websites, "Is there any of them that can only be browsed and used on mobile phones or tablets?"

Lu Yang thought for a while, "You mean 'Huaxia Annual Ring'? It's relatively small, and there's not a lot of information, scattered, and very little useful. Some people don't like to exchange academics, but just chat on it. I don’t usually use it very much. I heard that it was made by a small studio.

"Lu Yang is right. This website is really not doing well. No wonder there are so few users." Liu Zhiqin downloaded and installed "Huaxia Annual Ring", "I'll check it out in detail. Flower team, you go out to work later. ?"

"I have some questions to ask Qiu Dakui." Hua Chong said.

As the leader of the serious crime team, Hua Chong dare not put all his weight on the Internet even though there has been progress on the Internet.After confessing a few words with Liu Zhiqin, he went straight to the interrogation room.

The household hammer mixed with Xu Yujiao's blood is too suspicious. If Qiu Dakui is not the murderer in Xu Yujiao's case, then the murderer must have set the blame on purpose.Before Qiu Dakui lost control of his emotions, Qu Zhi and others didn't get any clues, and he was trapped in Tang Su's case, so he couldn't spare the energy to have a good chat with Qiu Dakui.Now that everything has been explained, it's time to find a breakthrough from Qiu Dakui himself.

"That hammer has been kept in the toolbox outside the window. I really don't know who took it." Qiu Dakui haggarded a lot. Dry trees.

His killing of Qiu Guoyong was a typical "passionate murderer", and his state at this time fully fits the characteristics of a passionate murderer a few days after the incident.

Hua Chong could tell at a glance that he was regretting.

Maybe I thought of Qiu Guoyong's goodness among the nine evils, maybe I thought of the lonely and helpless Qiu Weiwei, maybe I thought of my life that was completely defeated.

But there is no medicine for regret in the world.

"Who knows that you used to keep your toolbox outside?" Hua Chong asked.

"How would I know?" Qiu Dakui was dejected. "In the past, that box was kept at home. Later, occasionally someone came to borrow wrenches and electric drills, especially electric drills. Not every household has this. My old man... Qiu Guoyong has a temper." It's so weird, if someone came to our house, if he didn't pay back the money, he would be unhappy. When I opened the door to get tools, he would yell and curse in the house, and said that someone knocked on our door and broke it, so we have to pay for it. I don’t bother arguing with him about this kind of thing. When others came to borrow things, I had to borrow them, so I simply put the box outside the window. There happened to be a small platform there, and anyone who wanted to use an electric drill would come and take it, and put it back after use. .It hasn’t been lost for several years.”

"Recall, who have you made enemies with?"

"Who can I make enemies with? I don't dare to cause trouble at all. I can bear it if I can. I can't bear it... Hey!"

I can't bear it, I have already killed it.

"Then Qiu Guoyong..."

Before he finished speaking, Hua Chong realized that this was a meaningless question.

If Qiu Dakui did not dare to offend others because of his cowardice, Qiu Guoyong offended the entire Daoqiao Road.

"Him?" Qiu Dakui laughed dryly, "Comrade policeman, you might as well ask me if he has offended anyone."

Hua Chong understood that this was a teasing, but he didn't take it seriously, so he said casually, "Oh? Who?"

But Qiu Dakui seriously thought about it, and said angrily after a few seconds: "Forget it, let's not talk about it."

Hua Chong heard something strange, "Who did you think of?"
