"Last time you said you had a friend who was good at computers?"

When the phone was connected, Luo Hongyun's voice came straight to the topic.

"Well, that's right."

Xia Xu nodded slightly, and said with a smile, "Uncle Luo, you came here for Dong Changhe's affairs, right?"

There was a hint of surprise in Luo Hongyun's voice: "You know?"

"It just so happens that I'm also investigating this matter. I guessed yesterday that you, Uncle Luo, will probably be involved as well."

Xia Xu smiled.

"Although these armed drones are not as weird as lycanthropes, they are more threatening and troublesome. It is difficult for ordinary organizations to handle them, so they can only be reported to us."

Luo Hongyun explained casually.

Xia Xu nodded slightly, and asked, "Uncle Luo, do you want to use network intrusion to track and locate Duan Zhiyi?"

"It seems that you know quite a lot."

Luo Hongyun laughed twice, and said: "Since this is the case, I won't talk nonsense, is your friend sure? We have actually consulted some experts, but the answers they gave are not very optimistic."

"You can try, and even if it doesn't work, I have other ways to find Duan Zhiyi, but it may take some time."

Xia Xu nodded thoughtfully.

He has naturally considered this plan by invading the drone through the network to locate Duan Zhiyi's location.

The essence of brain control technology is actually to analyze brain waves, and the interaction between drones and control terminals is actually carried out through magnetic waves, which are also network signals.

Therefore, there must still be a network connection between Duan Zhiyi and the drone. In theory, if the drone can be hacked, it is possible to reverse locate Duan Zhiyi's location.

But this is only in theory, the difficulty is very large, and there are many problems to be solved.

We must know that drones were originally based on military use, and many people believe that they are an indispensable means of future warfare.

How to counter unmanned aerial vehicles, to be precise, how to counter communication interference is a subject of intensive research in modern warfare. If it is really that easy, there is no need to study it.

Not to mention, the first important point is that the control of drones is usually not carried out through the "network" in the conventional sense. It does not pass through the Internet and mobile operator networks, but based on its own radio transmission module. , which is equivalent to self-built WIFI and LAN.

The drone controlled by Duan Zhiyi may use some self-made signal base stations to amplify or transfer signals, but the terminal must also use this method.

Because civilian networks are implemented based on the operator's base station, if he is stupid enough to directly connect the drone to the operator's mobile network, the range of his drone's activities can be easily detected.

Therefore, if you want to invade this kind of drone, you must first access its communication frequency band. If you want to connect, you must first figure out the frequency band it uses, and you must get close enough to enter its signal coverage.

But once it enters the signal range, it means that it may encounter concentrated fire from those armed drones at any time. Even if this is solved, it will face a series of network and communication technology problems such as signal encryption, and the other party may disconnect from the network. , or the last one found out may be only the base station where the other party transfers the signal.

This is also the reason why Xia Xu went to Huichuang Hi-Tech in the first place. Even if he wanted to find Duan Zhiyi through hacking, at least he had to solve the personal safety problem first.

However, Zhou Xiaodong's spy drone is an unexpected harvest. It can be used to try to connect to Duan Zhiyi's drone communication. Let them debug it at that time. If it succeeds, the rest will mainly be electronic warfare on the network. .

This is the hardest.

Because what needs to be faced may be a completely unfamiliar system and encryption mechanism, which means that a lot of trials and temporary code writing may be required, and it cannot be completed in a short time or even a day or two.

However, the other party only attacked briefly by surreptitious people, and they may continue to commit murder at any time, there is no time at all.

But...

This was probably the last thing Xia Xu needed to worry about.

I have Admiral Meng Bochao and God General Xiaobaihua, but I still can't figure out just Zhiyi?

"Is that the Uncle Luo you mentioned?"

After quietly listening to Xia Xu's conversation, Tang Youxin asked curiously after he hung up the phone.

Because Duan Zhiyi and intrusion tracking were mentioned again, she had been quietly paying attention just now.

"That's right, it's called Cao Cao, Cao Cao is coming, and your mission is here."

Xia Xu put away his phone and smiled slightly.

Xiao Baihua was eager to try: "I just want to track down that Duan Zhiyi, right?"

"That's right."

Xia Xu nodded, and his expression suddenly became serious: "This Duan Zhiyi is a murderer who controls an armed drone to kill people remotely. He is extremely vicious, and he must be caught as soon as possible."

"I, I will try my best."

Tang Youxin seemed very lacking in confidence.

Seeing her appearance, Xia Xu encouraged her: "You heard it just now. This is a task given by the official special department. If you complete this task, you will make a great contribution, and you can use this as your resume to enter the National University of Science and Technology."

"I will work hard."

Tang Youxin lifted her spirits and mustered up her courage.

Xia Xu added: "There should be bonuses, there must be hundreds of thousands, and I will give you a commission at that time."

"Really?"

Tang Youxin's eyes lit up, and she waved her small fists, revealing strands of determination on her face: "I, I will definitely be able to catch him out!"

"That's right, that's it, keep this posture."

Xia Xu couldn't help crying and laughing when he saw this.

He kept stuffing money and was unwilling to ask for it. He almost forgot that this little girl was actually a money addict.

It's a pity that being a fan of money is not enough to break his introverted character.

When she followed Xia Xu to the office building of the special department in Star City early the next morning, she instantly regained that guilty look, and looked timid, holding Xia Xu's clothes along the way like a little follower.

After all, this is a real government office building, a high-rise compound, remote and deserted, yet majestic and dignified. For many ordinary people, it is a place where people subconsciously restrain their voices.

This was the first time she had come to this kind of place, if she hadn't followed Xia Xu, she wouldn't have dared to come here alone.

"Boss, don't be like this. You are a master, a master, a master. Show your aura. Look at the boss, strolling around is like going back to your own home."

Meng Bochao, who came with him, laughed and joked.

"I don't know who stood outside and looked around before I came, and dared not enter the door."

Xia Xu looked at him with contempt.

This guy is also a dead house who is afraid of life, and running here is probably not much better than Tang Youxin. Right now, he is just trying to hold on and relax with nothing to say.

The two were bickering, and Tang Youxin beside her couldn't help but gradually bend her eyes into crescents.
