Ran Sinian opened his eyes and could already see the gate of his community through the car window, and he said to Rao Pei'er beside him: "Pei'er, you go back to rest first, I want to go back to Chen's house to confirm some things.|"

"Huh?" Rao Pei'er glanced at Ran Sinian quite distressedly, and then drove the car past the gate of the community without hesitation, intending to take the lead in front, "Big detective, you better concentrate on resting and thinking about the case, I'll send you back." ”

Ran Sinian smiled with satisfaction, "It seems that the position of my assistant belongs to you, so let's do it, as your salary as an assistant, the rent is free." ”

When Rao Peier heard that she didn't have to pay rent, she shouted excitedly: "No problem, I can't be an artist or star, and the assistant is still no problem, absolutely competent!" ”

Ran Sinian looked at Rao Pei'er's excitement, and couldn't help but say distressedly: "I've wronged you." ”

"No grievances, no grievances, to be honest, I think being able to be a detective's assistant to help solve the case is much more fulfilling than pretending to scratch my head in front of the camera every day." Rao Peier said sincerely.

Soon, the two rushed back to the old community where the Chen family was located and walked into the Chen family's unit again.

Standing outside the door of Chen's house, you can clearly hear the sound of the couple arguing and throwing things inside, mixed with Zhang Yue's crying and Chen Guobin's cursing.

Rao Pei'er wanted to knock on the door immediately to stop the quarrel between the two, but was stopped by Ran Sinian, "This kind of thing will break out sooner or later, you can persuade it for a while, but you can't persuade it for a lifetime, let them quarrel." Let's get down to business first. ”

"What's the matter?" Rao Pei'er asked curiously, "What exactly do you want to come back to confirm?" ”

Ran Sinian didn't answer, took out his mobile phone and started to connect to the wireless network, and took out a piece of paper from his pocket and handed it to Rao Peier.

Rao Peier took the piece of paper and asked, "What is this?" Is this what you just wrote in the car? ”

"Yes, these password-like alphanumeric combinations are the result of my dream just now," Ran Sinian briefly described his dream before concluding, "I think that with a tablet, Chen Jiakui must want to access the Internet, and his parents can't install broadband at home, they don't even know that Chen Jiakui has a tablet, so if they want to go online, they can only rub the Internet." These passwords are the IFI passwords of the neighbors' homes that Chen Jiakui managed to know. ”

Rao Peier suddenly realized, "That's right, rubbing the net is indeed the best and only choice for Chen Jiakui, but he only needs to remember a neighbor's IFI password, why did he remember five or six?" ”

"I'm afraid it's because some neighbors occasionally turn off the Internet at night, and Chen Jiakui's Internet access time is probably only at night, when his parents are asleep, but also when the neighbors are asleep, he can take his tablet to search for available networks and passwords in the corridor to surf the Internet." Ran Sinian said as he selected a searched wireless network and entered the password on the slip of paper.

Rao Peier also immediately took out her mobile phone, selected another searched network, and began to enter the password from the beginning.

Five minutes later, when Ran Sinian entered the fourth password, he finally succeeded in connecting to the Internet. Rao Pei'er also successfully connected to the Internet after entering the third password.

"It seems that my idea is right, and now there is no need to try the remaining passwords one by one, this is indeed the proof of Chen Jiakui's rubbing the Internet." Ran Sinian signaled that he could go to Chen's house again to talk to Chen Jiakui's parents.

Rao Peier knocked on the door of the Chen family and muttered in a low voice: "This pair of parents is really unqualified, they don't know that their children secretly go out at night, and now that the children are lost, they know that they are quarrelling." ”

Ran Sinian sighed helplessly and said: "I can understand their current state, they are all laymen in the market, how can they be calm and calm and rational at this time?" Alas, it's just that I pity Chen Jiakui's child. ”

The door in front of him opened, and standing at the door was Chen Guobin, who was full of murderous face. Chen Guobin saw that it was Ran Sinian and Rao Peier, his face softened slightly, and he didn't speak, just turned around and went back to the house.

Ran Sinian and Rao Peier entered the door. When Zhang Yue saw the two of them, he immediately rushed over and asked, "Is there any news from Xiaokui?" Did you find it? ”

Ran Sinian shook his head, "There is no news about Xiao Kui yet, we are here this time to ask about Xiao Kui again." Does Xiaokui usually surf the Internet? ”

Zhang Yue nodded blankly and said with a sigh: "Alas, how can there be children nowadays who don't go online?" Even in my family's economic situation, children must go online! How? Xiaokui's Internet access is related to his kidnapping? ”

Rao Peier pouted, Zhang Yue still stubbornly believes that Chen Jiakui was kidnapped, and what Ran Sinian said before that Xiaokui took the initiative to leave with Zhang Xiao, it seems that she didn't listen to it at all, she instinctively evaded responsibility, and was unwilling to admit that the child ran away from home to escape from the family and parents who annoyed him.

"Yes, of course it does, I suspect that Xiao Kui got in touch with the kidnapper, that is, Wang Xiao, through the Internet, in other words, Wang Xiao communicated with Xiao Kui through the Internet, so that Xiao Kui fell into his trap and willingly followed him," Ran Sinian hesitated, but still told Zhang Yue about the tablet, Xiao Kui secretly went to the corridor at night to rub the Internet with the tablet, and then said, "I think, this tablet eight achievements were given to Xiao Kui by Wang Xiao, Before Xiao Kui received the tablet, he had already established contact with Wang Xiao through the Internet, so I want to know, what you know, Xiao Kui's way to access the Internet. ”

Zhang Yue didn't seem to understand what Ran Sinian meant, but still introduced: "We didn't want Xiaokui to go online at first, we thought that that thing would definitely affect learning and be addictive." But now the school, the teacher, what kind of class group do you want to get, the parent group and the like, the teacher will often assign some homework in the group to inform some things, Xiaokui's classmates can almost all go online, sometimes the teacher informs what to bring tomorrow, the whole class has brought, and Xiaokui doesn't know. Alas, our family's conditions are not good, not to mention the monthly Internet fee, not even the money to buy a computer for the child, there is no way, I can only let Xiaokui go to the same school to surf the Internet, Xiaokui's classmate Xie Gang lives in the fourth building next door, sometimes the two children do homework together, and then Xiaokui uses Xie Gang's computer to surf the Internet for a while. ”

"Xie Gang?" Ran Sinian got up, "Where is the address of Xie Gang's house?" ”

Zhang Yue saw that Ran Sinian was in such a hurry, and immediately got up and put on his coat, "I'll take you there." ”

Chen Guobin was originally in the bedroom, but when he heard Zhang Yue say that he was going out, he immediately came out and shouted: "Where are you going?" Going on a date with a wild man? ”

Zhang Yue didn't bother to say more to Chen Guobin, so he only dropped one sentence: "I'll go with Mr. Detective to find my son!" ”

Rao Peier glanced at Chen Guobin fiercely, didn't bother to explain, and went out after him.

The group of three quickly arrived at Building 4 of the community, and before entering the unit, Rao Peier noticed that Chen Guobin was also following them. She thought, this Chen Guobin looks like a big boss on the surface, not at all like a high-IQ criminal who will lure a little boy through the Internet, and following his wife at this time is either really worried that his wife will take the opportunity to go out to meet Xiao Kui's biological father, or he is worried about his wife and Xiao Kui, but he just refuses to admit it.

Today is Tuesday, Xie Gang is still in school, Xie Gang's parents are not at home, fortunately there is a retired grandmother Xie Gang at home. Zhang Yue explained to this grandmother who had a few faces, and Grandma Xie heard that looking at Xie Gang's computer could help Zhang Yue find a child, so she immediately agreed.

Ran Sinian was a little embarrassed, because he didn't come to see Xie Gang's computer, but to take Xie Gang's computer away and take it to the police station for the Internet police to carefully check whether there were still traces of Chen Jiakui chatting online. He told Grandma Xie that he wanted to take away the computer, but Grandma Xie resolutely disagreed, no matter how Ran Sinian explained that she would return the computer, Grandma Xie just said that she couldn't be the master, so she could only let them watch it here.

Ran Sinian thought about asking Qu Zichong to send a policeman to take the computer directly, but looking at Grandma Xie's stubbornness, I'm afraid it will still take a lot of time to talk about it, so it is better to directly ask Qu Zichong to send an Internet policeman over. Wait a minute, instead of looking for the Internet police, it is better to find He Qirui, he is definitely no worse than the Internet police, maybe he is slightly better.

Thinking of He Qirui, Ran Sinian immediately took out his mobile phone and broadcast the call.

In the spare time of Ran Sinian's phone call, Rao Peier sat in front of the computer, she opened the browser, and found the record of the web pages opened in the recent period, and one of the web pages caught her attention. Someone once searched for a blood group genetic pattern table on this computer, and the time was half a month ago.

Rao Peier waited for Ran Sinian to hang up the phone, pointed to the screen and said: "I guess that this blood group genetic pattern table should be what Chen Jiakui searched for when he was surfing the Internet here, that is to say, his doubts about whether he is Chen Guobin's biological son are no longer limited to the subconscious, his consciousness has been perceived!" ”

Zhang Yue finally understood Rao Peier's words this time, and said in surprise: "Half a month ago? Half a month ago, Xiao Kui was sick, and when we took him to the hospital for a blood test, Xiao Kui's blood type was on the test sheet at that time! Xiao Kui is blood type B! ”

Rao Peier asked: "Then you and Chen Guobin are A and A, O and O, or A and O blood types?" ”

"Yes, our unit has an annual physical examination, I am blood type O, Guobin is blood type A, we have long known our blood type." The more Zhang Yue spoke, the quieter his voice became, and he buried his head in embarrassment.

The three of them waited in the living room of Xie's house for more than half an hour, chatting for more than half an hour with Grandma Xie, a lonely old man who had no one to talk to on weekdays, and He Qirui finally arrived.

"I'm sorry to keep you waiting, I just sent Xiaomei home, and we were in the police station before." He Qirui explained apologetically as soon as he entered the door.

Ran Sinian asked, "How is it?" Xiaomei has seen the photos of the two suspects? Aren't they the Zhang Xiao of the year? ”

"No, Xiaomei remembers that Zhang Xiao is much younger than the two of them, with a medium build, and a very popular appearance," He Qirui said as he sat down in front of the computer, "It's a pity that Xiaomei can't remember what Zhang Xiao looks like, and this portrait was not painted in the end." After all, Xiaomei has too many customers, especially a customer who came and went so long ago. ”

Ran Sinian nodded understandingly, "Yes, I expected this to be the case, even if I am not face blind, it is impossible for me to remember the customers from so long ago." ”
