It should be noted that Wang Zhuo possesses two sets of X-ray vision systems—one is his eyes, and the other is Siyuan. The visual X-ray possesses unparalleled advantages in real life, but it is utterly useless online.

Fortunately, Siyuan’s abilities complement this perfectly, making the combination flawless. As a master cracker and a highly skilled veteran hacker, Siyuan excels at finding ways to break through problems, especially the ability to extrapolate from one case to others.

Thus, as soon as she heard Wang Zhuo’s request, she immediately conceived of an alternative solution: what if he just wanted to check the communication records of a mobile number? It didn’t matter if the number was unknown; there is no such thing as a perfectly sealed wall in this world!

Many people may not realize that in television crime investigation programs, the narrator often uses the phrase, "The police utilized technical means," to briefly gloss over the investigative process. What exactly are these "technical means"?

For a programming expert like Siyuan, who specializes in cracking, it was instantly discernible. In fact, when a mobile phone communicates with the outside world—or even when it simply has its card inserted and is powered on without making a call—it submits certain information to the wireless communication operator.

This information naturally includes the mobile number, along with the phone's current location, which is recorded by the base station it is communicating with. It also includes some identity information about the phone, such as the network access permit.

This network access permit corresponds to each mobile phone and is a unique identifier. Using this information, Siyuan could perform a reverse lookup to see which mobile numbers have also used this phone, thereby discovering the number of the SIM card hidden in the lining of Nan Bing's cosmetic bag.

Through a "backdoor," Siyuan quickly logged into the corresponding management platform, then pulled up all the information for Nan Bing's mobile number she had just queried from the database. From there, she extracted the network access permit number the phone was last tethered to.

By querying the data using this permit number, she found all the mobile card numbers that had ever used this phone. There were seven numbers in total, presented to Siyuan in a table format.

The first few numbers had not been used for a year and were all ordinary numbers. Their communication records indicated they were likely discarded after the prepaid balance was used up.

Her gaze quickly fell upon the last two numbers. One was the known, frequently used contact; the other had little call activity—only two or three calls a day, more text messages, and the last shutdown was this morning.

It seemed this was the number Wang Zhuo needed. "Found it.

The number is..., and this card only has call history with one other number, which is...," Siyuan rapidly relayed the two numbers to Wang Zhuo, then asked, "Should I check their real-name registration records?" "No need to check. How could a temporary card possibly be registered under a real name?" Wang Zhuo decisively refused, instructing, "Send the numbers and detailed call records to my phone, and then wait for my message.

I'll contact you if anything comes up." "Deal!" Siyuan agreed cheerfully, quickly downloading and organizing the data, and sending it to Wang Zhuo’s phone mailbox. In television programs, viewers often encounter confusing segments: after a major case occurs, relevant leaders might set a deadline for solving it, perhaps twenty-four hours or three days.

Viewers can't help but wonder: Can the meticulously planned actions of criminals really be solved and apprehended so easily? Indeed, there are extremely capable criminals in the world who are cunning and strategic, ultimately managing to evade justice.

However, more criminals underestimate the advancement of current technology and often leave behind tiny clues, resulting in their capture by investigators and eventual bringing to justice. The query platform Wang Zhuo and Siyuan just used was a special system reserved for security purposes.

If it were merely a common mobile phone theft case, no one would mobilize this platform for a mere few hundred yuan in property loss. But if a homicide or robbery occurred, this platform could trace the usage and whereabouts of both parties' phones, thus achieving investigative goals.

This analysis and querying took over ten minutes. Just as Wang Zhuo was about to return to the private room, he saw Sun Donghao walking out alone.

"Why did you come out?" Wang Zhuo stepped forward and asked casually. "I waited and waited for you to come back, so I came out to look," Sun Donghao laughed.

"How was it? Did you take care of things?" Wang Zhuo forced a dry laugh and said meaningfully, "Not quite yet, but I have prepared some things that I can show you now." "What things?" Sun Donghao blinked curiously.

"Here, come look over here," Wang Zhuo pointed to the window at the end of the hallway and led him over. Taking out the communication log Siyuan had sent him, Wang Zhuo beckoned for Sun Donghao to lean in close to show him.

"This is... hey?

This thing is kind of interesting!" Sun Donghao was quickly intrigued because this data log contained the start and end times of calls, corresponding base station locations, and power-on/off times—it was clearly different from a log printed or queried through normal channels. "Whose numbers are these?" he mused, teasingly adding, "I feel like they're being sneaky, like they're doing something illicit." Wang Zhuo managed a wry smile and said with mock annoyance, "You guessed right; they are indeed doing something shady." Sun Donghao’s words were not wild guesswork.

The communication details in the log did suggest suspicious behavior between the two numbers. Nan Bing’s number was often powered off for long stretches, and when briefly turned on, it would be shut off quickly, or remain on only for an hour or two late at night.

Combined with the fact that this number only communicated with one other number, there was bound to be some trickery involved. "Criminals?" Sun Donghao’s eyes lit up as he guessed speculatively, "Or maybe they're involved in an improper romantic affair?" Seeing his eager look, Wang Zhuo helplessly pursed his lips.

"Be serious; this concerns you." "Uh..." Sun Donghao immediately fell silent, looking at Wang Zhuo with some surprise, waiting for him to elaborate. "This number belongs to Nan Bing; I don't know the other one yet," Wang Zhuo skipped the pleasantries and pointed directly at the phone screen.

"You can probably see that their daytime calls are very short—maybe during bathroom breaks or other brief moments. At night, these two numbers sometimes appear under the same base station; that means they met up." "Huh?" Sun Donghao was completely stunned, never expecting Wang Zhuo to suddenly say something like this.

"I hope this is a misunderstanding, but judging by your expression, I fear it isn't," Wang Zhuo said earnestly. "Nan Bing probably has another man outside of you.

I don't know who owns that other number or what relationship they have, but since you are completely unaware of this, there must be a hidden story." "This, this..." Sun Donghao swallowed hard and forced a smile. "Where did you get this call record from?

Do you have other evidence?" Wang Zhuo shook his head. "I don't have proof right now, but I can get it anytime.

Are you prepared mentally?" Sun Donghao's already fair complexion turned somewhat pale. After hesitating for a moment, he gritted his teeth and nodded.

Wang Zhuo quickly fiddled with his phone a few times, bringing up a very simple-looking application and showing it to him. "In the top field here, you enter the caller ID number.

In the bottom field is the called number. Let me demonstrate for you first." He swiftly entered 95588 in the top field, then entered Sun Donghao's mobile number in the bottom field, and pressed the dial button.

Soon, Sun Donghao's phone vibrated. Taking a look, the caller ID clearly showed 95588.

Then, as soon as Wang Zhuo hung up, Sun Donghao's phone automatically disconnected as well. Sun Donghao nodded.

"I know this technique; it's implemented via VoIP calls. Some people use it for fraud; it was exposed on TV." "Let's try another one." Wang Zhuo quickly entered a string of digits into the first field, saying as he dialed, "This is the number Nan Bing frequently contacts." The call went through quickly.

After verifying it was correct, Sun Donghao nodded with a complex expression. Normally, if he knew Wang Zhuo had such a new and fun piece of software, he would try to borrow it for some amusement, but he was in no mood for fun now.

"This is what I plan to do," Wang Zhuo explained to him. "I will pretend to be that number and call Nan Bing's frequently used phone once, let it ring twice, and hang up.

Then we'll go back in. Nan Bing will surely find an excuse to leave temporarily to contact that person.

We will call him again right before she can, and listen to what she says." Sun Donghao grimaced. "My whole world is spinning; I'll do whatever you say." Wang Zhuo nodded and followed the plan, dialing Nan Bing’s number.

Simultaneously, he used his X-ray vision to monitor Nan Bing’s behavior in the private room. Ring, ring...

After three rings, Nan Bing took out her phone from her purse. Seeing the number displayed, she paused slightly, hesitating whether to answer, when the call abruptly terminated.

"Okay, let's go back," Wang Zhuo whispered to Sun Donghao. "Act naturally.

If you can’t manage it, just go to the side to adjust your jacket after we get in; don't talk to her." He led Sun Donghao back into the private room. Nan Bing was playing 'Fruit Ninja' with her phone.

Seeing the two enter, she looked up and smiled. "Where did you go?

Why did it take so long to come back?" "Just talking about some things," Wang Zhuo gave a slight, forced smile, while Sun Donghao very obediently walked to the side to adjust the jacket hanging on the wall. "I'm going to the restroom too," Nan Bing stood up gracefully, naturally slipping her phone back into her handbag and holding it.

"Haozi, keep chatting with Wang Zhuo for a bit, and call someone else to see how far along they are." "Okay," Sun Donghao replied, without turning around. As soon as Nan Bing walked out, Wang Zhuo immediately followed her with his X-ray vision, while motioning for Sun Donghao to sit next to him.

"I'm going to call her now. We'll use the silent function so we can hear what she says." Sun Donghao nodded, his brow tightly furrowed.

He knew Wang Zhuo was never one to act without reason; since he was doing this, it meant he was one hundred percent sure, and this was just a way to prove it to him. He had thought it was going to be a happy marriage, but now it seemed a major crisis was looming!

What Sun Donghao didn't know was that Wang Zhuo was doing this out of sheer necessity. Wang Zhuo couldn't just tell him directly, "Bro has X-ray vision and saw that the child Nan Bing is carrying isn't yours." That would sound so unbelievable that not only would Sun Donghao not believe it, but Wang Zhuo himself would find it absurd!
