"Last time you said you had a friend who was good at computers?"
The call was connected, and Luo Hongyun's voice came straight to the point.
"Yes, that's right."
Xia Xu nodded slightly and said with a smile: "Uncle Luo, you are here for Dong Changhe's matter, right?"
There was a hint of surprise in Luo Hongyun's voice: "You know?"
"It just so happens that I am also investigating this matter. Yesterday I guessed that Uncle Luo and you guys would probably get involved as well."
Xia Xu smiled.
"Although these armed drones are not as strange as beastmen, they are more threatening and troublesome. It is difficult for ordinary institutions to handle them, so they can only be reported to us."
Luo Hongyun explained it casually.
Xia Xu nodded slightly and asked, "Uncle Luo, are you trying to use network intrusion to track down Duan Zhiyi?"
"It seems you know a lot."
Luo Hongyun laughed and said, "In that case, I won't waste my words. Is your friend sure? We have actually consulted some experts, but the responses they gave were not very optimistic."
"You can try. Even if it doesn't work, I have other ways to find Duan Zhiyi. It just may take some time."
Xia Xu pondered and nodded.
He had naturally considered the option of reversely hacking into the drone through the Internet to locate Duan Zhiyi's position.
The essence of brain control technology is actually to analyze brain waves. The interaction between the drone and the control terminal is actually carried out through magnetic waves, which is also a network signal.
Therefore, there must be a network connection between Duan Zhiyi and the drone. Theoretically, if the drone can be hacked, it is possible to reversely locate Duan Zhiyi's position.
But this is only in theory. It is extremely difficult and there are many problems that need to be solved.
You should know that drones were originally designed for military purposes, and many people believe that they are an indispensable means of future wars.
How to counter drones, or more precisely, how to counter communications interference, is a topic of intensive research in modern warfare. If it were that easy, there would be no need to study it.
Without going into details, first of all, it is very important to note that the control of drones is usually not carried out through the "network" in the conventional sense. It does not go through the Internet and mobile operator networks, but is 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 adopt this method.
Because civilian networks are all based on the operators' base stations, if he is stupid enough to connect the drones directly to the operators' mobile networks, the activity range of his drones 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 range.
However, once you enter the signal range, it means that you may encounter concentrated fire from armed drones at any time. Even if this problem is solved, you will still face a series of network and communication technology problems such as signal encryption. The other party may also disconnect from the network, or what you find in the end may just be the base station that the other party uses to transfer signals.
This is also the reason why Xia Xu went to Huichuang Hi-Tech first. Even if he wanted to find Duan Zhiyi through hacking methods, he had to at least solve the personal safety problem first.
However, Zhou Xiaodong and his team's spy drone was an unexpected gain. It can be used to try to access Duan Zhiyi's drone communications. They can then debug it. If successful, the rest will mainly be network electronic warfare.
This is the hardest part.
Because you may need to deal with a completely unfamiliar system and encryption mechanism, which means that it may require a lot of attempts and temporary code writing, which cannot be completed in a short time or even a day or two.
But the other party only launched a short-term attack that appeared out of nowhere, and could continue to kill people at any time, so there was no time at all.
But...
This is probably the issue that Xia Xu doesn't need to worry about the least.
I have General Meng Bochao and Godly General Xiao Baihua, so how can I not handle Duan Zhiyi
"Is that the Uncle Luo you mentioned?"
After listening to Xia Xu's conversation quietly, Tang Youxin waited until he hung up the phone before asking curiously.
Because Duan Zhiyi and intrusion tracking were mentioned again, she had been quietly paying attention.
"That's right. Speak of the devil and he will appear. Your mission is here."
Xia Xu put away his phone and smiled slightly.
Little White Flower was eager to try: "We want to track down Duan Zhiyi, right?"
"That's right."
Xia Xu nodded, his expression suddenly becoming serious: "This Duan Zhiyi is a murderer who controls armed drones to kill people remotely. He is extremely vicious. We must catch him as soon as possible."
"I, I'll try my best."
Tang Youxin seemed to lack confidence.
Seeing her like this, Xia Xu encouraged her, "You just heard it. This is a task assigned by a special official department. If you complete it, you will have made a great contribution and you can use this as your resume to enter the University of Science and Technology of China."
"I will try my best."
Tang Youxin cheered up and mustered up her courage.
Xia Xu added: "There should be bonuses, hundreds of thousands for sure, and you will get commissions when the time comes."
"Really?"
Tang Youxin's eyes lit up, and she waved her fist, with a look of determination on her face: "I, I will definitely find him out!"
"Yes, that's it. Keep it like this."
Xia Xu couldn't help but laugh and cry when he saw this.
She kept giving him money but refused to take it. He almost forgot that this girl was actually a money-grubber.
Unfortunately, his love for money is not enough to break his introverted personality.
When she followed Xia Xu to the special department's office building in Xingcheng the next morning, she instantly regained her guilty look and looked timid. She held Xia Xu's clothes all the way like a little follower.
After all, this is a genuine government office building with high gates and a large courtyard. It is remote and deserted, yet majestic and solemn. For many ordinary people, it is a place where they subconsciously control their voices when speaking.
This was her first time coming to such a place. If she hadn't been with Xia Xu, she wouldn't have dared to come here alone.
"Boss lady, don't be like this. You are an expert, an expert, show your power. Look at the boss, he is just like he is at home."
Meng Bochao, who came along, laughed and joked.
"I don't know who was standing outside and peeking around before I came, but didn't dare to come in."
Xia Xu looked at him with disdain.
This guy is also a cowardly otaku. He is probably not much better than Tang Youxin when he came here. At this moment, he is just trying to pretend and make small talk to relax.
The two of them were arguing with each other, and Tang Youxin on the side couldn't help but let her eyes gradually bend into crescents.
