Han Xu walked to the table beside the bed and touched the laptop with cartoon patterns on the shell with gloves on. "I used to have an identical one. It was a birthday gift given to me by my father before he died." Only after hearing this did Guo Jia know that Han Xu had lost his loved ones at such a young age, and he could not help but comfort her. Although Han Xu had traveled through time, some memories of his original body still had a significant impact on him. For example, seeing something reminds you of someone, and seeing familiar things will inevitably make you feel nostalgic. However, he quickly calmed down, discarded the emotional interference that should not exist when investigating a case, and began to focus all his energy on the laptop in front of him. This laptop was the most popular style at the time, and the price was not cheap. It can be seen that Yang Yuanchi loved his baby daughter very much. Guo Jia said, "This brand of computer is almost worth tens of thousands. Teacher Yang is very willing to spend money on children." Han Xu suddenly thought of a question and blurted out, "Doesn't Yang Lu have a mobile phone?" Guo Jia shook his head affirmatively, "No, Teacher Yang was afraid that her daughter's mobile phone would affect her academic performance, so she didn't buy a mobile phone for Yang Lu, but she was willing to spend money to buy her the best computer."
Han Xu couldn't help but sigh and didn't say much. Guo Jia continued, "If the child had a mobile phone, he could call the police in time when he encountered danger, and perhaps the result would be completely different." "Yang Lu probably had been eyeing him early in the morning. Even if he had a mobile phone, he probably wouldn't have had the opportunity to call the police." Han Xu told the truth. Guo Jia thought that it was true, so he was relieved. At this time, Han Xu had already turned on the computer, but after the boot animation, the screen showed that he needed to enter a password. Before Han Xu turned his head in confusion, Guo Jia had already said, "The password is the child's birthday, XXXXXX." Han Xu entered it as he was told and successfully entered the system desktop. The desktop of Yang Lu's laptop is quite simple, with only a few commonly used icons, and it is as clean as if it has never been used. "Alas, this computer was bought just a week ago, and the child had an accident. We have checked it, and there is nothing inside. The technician said that even the number of times it has been turned on can be counted on two hands." Han Xu nodded and opened the webpage to check Yang Lu's browsing history. Guo Jia didn't say much this time, because it was also empty. Han Xu turned his head to look at Guo Jia in confusion, wanting an answer. "There is no browsing history at all, which means that Yang Lu didn't even have any Internet records after getting this laptop. Look at that," Guo Jia said, pointing to an inconspicuous icon on the display screen, "That is the software used for online classes. Yang Lu is a very sensible child and knows how to study. His grades have always been among the best in school. Unfortunately..." After hearing this, Han Xu couldn't help but sigh, but his hand did not stop, but quickly double-clicked the icon. This is a very common online course software, but unfortunately, a dialog box popped up again, requiring the account and password to be entered. Fortunately, the account had been entered once and saved, and a string of numbers lay quietly in the input box. But the password below was empty, without any memo record. "What is the password?" Han Xu asked in confusion. Guo Jia was stunned for a moment, and shook his head blankly, "I don't know, we haven't checked this, it's just an online course software, there is no need to check it, right?"
Han Xu frowned, subconsciously thinking that this software might hide some clues. "Wait a minute, I'll ask Teacher Yang to see if he knows." Guo Jia thought of Yang Yuanchi, left a sentence, and went out to ask. After waiting for a while, Guo Jia and Yang Yuanchi appeared behind Han Xu. Yang Yuanchi looked at the strange dialog box and shook his head, "I really don't know this password. I bought a computer for Xiaolu so that she could take online classes, but I don't know the software account password. Maybe my wife knows it, but she..." Han Xu saw Yang Yuanchi stop here and knew what he wanted to say, "Then I'll try to open it." Guo Jia asked in confusion, "You know computers?" Han Xu didn't know any of this, he just wanted to try to guess the password that Yang Lu entered. Generally speaking, the passwords chosen by most people are easy to remember, such as birthdays, or numbers that are very memorable to themselves. Han Xu had just tried it, and the power-on password was Yang Lu's birthday, but this password was obviously not used any more. "Teacher Yang, when is your birthday?" Han Xu changed his mind. Yang Yuanchi was stunned for a moment, then quickly understood and reported a string of numbers. Han Xu entered it as he said, but it still showed a prompt that the password was entered incorrectly. After seeing the prompt, Yang Yuanchi reported another string of numbers, and then said, "This is my wife's birthday, Officer Han, please try it." Han Xu nodded and entered it again, but it was still wrong, and it showed that the password was entered incorrectly. Han Xu saw Guo Jia was about to make a move, and hurriedly stopped him with his eyes. Other people's parents' birthdays were wrong, how could you guess your own birthday correctly? Guo Jia was also desperate and embarrassed. Han Xu sat in front of the computer desk, looked around the surrounding environment again, and asked Yang Yuanchi, "What numbers does Xiaolu usually like?" "Numbers?" Yang Yuanchi was stunned for a moment and didn't react. Guo Jia reminded, "It's just that he likes Arabic numbers, 123456789!" Yang Yuanchi understood, frowned and thought for a while, but still shook his head, "I'm usually busy with work, and I don't go home many times throughout the year. I'm not a good enough father and don't understand my child well enough." Guo Jia hurriedly comforted him, "Nowadays, there is a generation gap between most parents and children. This kind of thing is normal. Brother Yang, you don't have to blame yourself. You want me to tell you what numbers my kid likes, but I don't know! It's just a number, how can we know that!" Guo Jia's words are still very effective, because it is a big truth. Although it hurts the child, there is nothing we can do about it! Han Xu had no choice but to enter a few Arabic numbers randomly, but he was still at a loss. "Is this online course software so important?" Guo Jia saw Han Xu holding on to a point and didn't quite understand. Han Xu did not explain too much, but instead set his eyes on the exquisite figurine on the computer desk. It was a figurine based on the protagonist of the comic "Seven X Sins". Han Xu picked it up and looked at it for a few seconds, then somehow entered a line of numbers into it...
