My friend arrived at 2 o'clock in the afternoon, and I told him that my uncle needed his help checking the computer, and the cost was 100,000 yuan. This guy is short of money, and he gets up at five o'clock and a plane arrives. I told him that I wouldn't come to him if I had something to do, and let him earn the money himself.

This person is a classmate of mine and has some technology on the computer, and he helped me last time I checked that website. As soon as I told him what I was asking for, he immediately understood, and without asking why, he immediately started to straighten out.

But as soon as he moved the computer in its entirety, he took a look at it and let out a "huh".

I asked what was wrong, and he said, "Your computer doesn't have an internet connection." ”

"Don't have an internet connection?"

"Look, there's no network cable."

I lay down and looked at it, and I was stunned. Sure enough, the back of the computer was slippery, and even a person like me who didn't have much computer knowledge could be sure that the computer had absolutely no network cable, because it only had a power cable connected to the socket.

"Wi-Fi?"

"No way. I don't have a Wi-Fi driver installed in my computer."

"So what's going on?" I wonder.

No way. Yes, my heart says. I've watched a TV series before. The computer inside can be connected to another computer in another world through some kind of spiritual power, and the people inside say that this kind of network is called "ghost network".

I don't know how it works, but it's definitely not a ghost net, and I suddenly realized that this is a big deal

I sat back down in front of my computer and calmed down. He said, "I'll have to take it apart to see what it's like, otherwise you're talking to yourself." ”

"I don't understand. You have to be more detailed. ”

"Theoretically, it can be done as well. You can set up two accounts in one computer to communicate with each other on the same computer. ”

"Don't need an internet connection?"

"No, though. Is there any actual content in your email exchange? ”

I nodded, "Of course." ”

"That can't be the case, I think there's something wrong with the case." He said:

I asked him if he would damage the machine, and he shook his head and said absolutely not.

He's fast. Obviously, I was used to installing computers in the computer city, and I quickly removed the shell of the main machine. It was full of circuit boards that I couldn't read: he tweezed around in it, and after reading it, his face turned pale, and he said to me, "Uncle, this is really fucking weird, there is no network card in here." ”

I didn't understand how serious this was, and with a puzzled expression, he said, "At the computer level, this is against the laws of physics. If you don't have a network card, it's absolutely impossible to receive any emails from the Internet. No way. The email you receive can only come from your computer itself."

"What do you mean?"

"Either you're emailing yourself, or your computer can email you."

I shook my head, it was absolutely impossible. "Absolutely impossible, you take a closer look." I said. Suddenly I remembered the last email from yesterday, and I damn it, is this computer smart, it saw me going out to smoke in this room, and it wasn't spying on my balcony somewhere else here?

I felt a chill run through my body. If so, are we raping it now? No, dissect it.

I quickly dismissed this ridiculous thought. There must be something strange about this. My classmate continued to study the inside of the chassis. Suddenly, he let out a "huh", shone a very thin white wire with a flashlight, and said, "I see." ”

"What is the reason?" I asked impatiently. "I don't know yet, but there's a strange wire here," he said. He fiddled with the white wire, which was very thin. He touched it all the way to the source of the wire, which was connected to the computer's power supply.

He immediately set his hands on disassembling the power supply. After disassembling the power supply, I used a screwdriver to pick out the white wire. It was found that the wire was attached to a very small electronic component.

I couldn't read at all and watched my classmate touch his chin. He thought about it for a long time. He said, "I can't believe what I've seen, I'm going to see this thing in this era." You may not understand what I said: this is a very primitive network card that uses a ground wire to pass the signal. It's a peer-to-peer network. The other person's computer is only connected to yours. In fact, it is a Morse code parser:"

"And where is he?" I don't want to know how it works at all.

"I don't know, he is using the ground wire of the power supply, which is a special line. Do you have a circuit diagram for this house? If so, I can help you find out. ”

I shook my head, needless to say, I don't know where that thing is, even if there was really such a thing before, the third uncle must have destroyed it. With the third uncle's prudence, it was impossible for him to let the possibility of exposing this line exist.

"The only way to do that is to rip out this line," he said. One end of the line is here. Then the other end can be found by following the line. As he spoke, he pointed to the socket embedded in the floor, "This is the source." We had to pry all the floors open to find the direction of this line, which must have another computer connected to it. ”

I thought about it and told him not to act rashly. I have to think about it, if the movement is too big, it will definitely be discovered, and it must be done lightly. "This private network travels a very short distance, and it can't be too far away from the house, otherwise it will involve a street transformer on the side of the road: so his location must not be too far from here, it must be within a few hundred meters, and it will be found out very quickly," he said. ”

"How much time do you think it will take?"

"It can be found in three hours at most."

I patted him and said, "Well, you can rest first, and we'll do it after it gets dark at night." You install the computer for me first. ”

The situation continues to change, and it will take time to wait.

Here's an email from me to keep the man waiting. In this case, this person will be waiting by the computer all the time. If I can find it, I'll be able to break down the door and catch someone.

I waited until it was completely dark, and then asked my classmate to wrap a flashlight in a cloth and start work.

The third uncle's home is actually an old-fashioned peasant house renovated, and all the wiring is open lines, but the third uncle added a layer to the ground for safety. My friend carefully pried the floor open, knocked through the protective shell on the outside of the protective wire, and ripped the wire out.

I ran to the second floor to see which of the external wires on the roof had been pulled.

Then I searched all the way down and found that the wire was directly connected to the outside of the house. I pulled out all the rivets that held this wire in place and continued to make my classmates twitch.

Then to the first floor. We followed the wire all the way to the courtyard. Then we saw the wires go straight down, all the way to the ground.

I wondered in my heart that the third uncle's yard was not big, only six or seven square meters, and there were four or five wires in that bundle, all of which went under the eaves of the wall, and only this one wire went underground.

The ground was littered with messy potted plants, more than a dozen of them. My friend and I carefully moved the pots one by one, and I was surprised to see a manhole cover:

The wires went all the way down to this manhole.

I never knew that there was this thing in the third uncle's house. There was a handle on the manhole cover, I went up to lift it, and found that it could be lifted, and it was pitch black inside, and my heart hung up.

There is a door.

I took a breath and said to my classmates, "Okay, just get here." "After taking him away, I immediately went to the house to get a flashlight, went to the manhole cover, took a deep breath, pulled it up and shone it down. (To be continued)
