My friend arrived at two o'clock in the afternoon. I told him that my uncle needed his help to check the computer, and the fee was 100,000. This guy was short of money, so he got up at five o'clock and flew there. I told him that I wouldn't come to him if I had something to do, and let him make the money on his own.

This person is a classmate of mine who has some computer skills. He helped me check the website last time. As soon as I told him my request, he immediately understood it and started making arrangements immediately without asking why.

But he just moved the whole computer, took a look at it, and said "Huh".

I asked what was wrong and he said, "Your computer is not connected to the Internet."

"No internet?"

"Look, there is no network cable."

I lay down and took a look, and I was stunned. Sure enough, the back of the computer was bare. Even a person like me with no computer knowledge could be sure that there was absolutely no network cable connected to this computer because it only had a power cord connected to the socket.

"wireless network?"

"Impossible. The wireless network driver system is not installed in the computer."

"Then what's going on?" I wondered.

Holy shit. This is it, I said to myself. I watched a TV series before. The computer inside can be connected to another computer in another world through some kind of spiritual power. People inside say that this kind of network is called a "ghost network."

I don’t know what the reason is, but it’s definitely not a ghost network. I suddenly realized that this situation is very important.

I sat back in front of the computer and calmed down for a while. He said: "I have to take it apart and take a look to know what's going on. Otherwise, you are just talking to yourself."

"I don't understand. Please explain in detail."

"Theoretically, this can be done. Two accounts can be set up in one computer and they can communicate with each other on the same computer."

"Don't need internet?"

"No, though. Is there any actual substance to your email exchange?"

I nodded: "Of course."

"Then it can't be like this. I think there must be something fishy inside the chassis." He said:

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

He is very fast. Apparently I was used to installing computers in the computer city, so I quickly removed the casing of the host machine. It was full of circuit boards that I couldn't understand: he used tweezers to knock around inside.

After reading it, his face turned pale and he said to me: "Uncle, this is really fucking weird. There is no network card in it."

I didn't understand how serious this was, and he said with a puzzled expression: "At the computer level, this violates the laws of physics. If you don't have a network card, it is absolutely impossible to receive any mail from the external network. Impossible. You receive The email you received can only come from your computer itself."

"What's the meaning?"

"Either you are sending emails to yourself, or your computer can send you emails."

I shook my head, this was absolutely impossible. "Absolutely impossible, take a closer look." I said. Suddenly I remembered the last email from yesterday. Damn it, could this computer be intelligent? It saw me going out to smoke in this room, not on my balcony somewhere else here?

A chill ran through my body. If so, are our current actions raping it? No, dissect it.

I quickly dismissed this ridiculous idea. There must be something fishy about this. My classmate continued to study the inside of the chassis. Suddenly, he said "Hey", illuminated a very thin white wire with his flashlight, and said, "That's it."

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

He immediately started to disassemble the power supply. After disassembling the power supply, use a screwdriver to pick out the white wire. Found a wire connected to a very small electronic component.

I couldn't understand it at all and looked at my classmate touching his chin. He thought for a long time. He said: "I can't believe what I saw, I actually saw this thing in this era. I said you may not understand: this is a very primitive network card, which uses ground wires to transmit signals. This is A peer-to-peer network. The other party's computer is only connected to your computer. In fact, it is a Morse code parser: "

"Where is he?" I didn't want to know how it worked.

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

I shook my head. Needless to say, I didn't know where that thing was. Even if it really existed before, my third uncle must have destroyed it. With Third Uncle's caution, he could not allow the possibility of exposing this line to exist.

He said: "The only way is to pull out this line. One end of the line is here. Then you can find the other end just by following the line." He pointed to the socket embedded in the floor, "Here it is. The source. We have to pry open the floor and find the direction of this line. Another computer must be connected to this line."

I thought about it and asked him not to act rashly. I have to think about it. If there is too much movement, someone will definitely find out. I have to do it lightly. He said: "The propagation distance of this kind of dedicated network is very short, and it cannot be too far away from this family's house, otherwise it will involve the street transformer on the roadside: Therefore, his location must not be too far from here, and it must be within a few days." Within a hundred meters, you can find it quickly.”

"How long do you think it will take at most?"

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

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

The situation continues to change and we will have to wait until midnight.

This is the email I sent, asking the person to wait a moment. In this case, this son of man will definitely be waiting by the computer when he is young. If I can find it, I can break down the door and catch him.

There was no reply from the other party, so I waited until it was completely dark and then asked my classmate to wrap a flashlight in a cloth and start working.

The third uncle's home is actually a renovated old farmer's house. All the wiring is open wire, but the third uncle added a layer on the ground for safety. After my friend carefully pried open the floor, he broke the protective shell outside the protective wire and pulled out the wire.

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 this wire was directly connected to the outside of the house. I pulled out all the rivets holding the wire in place and continued to jerk my classmate.

Go to the first floor again. We followed this wire all the way forward and came to the yard. Then, we saw the wires going straight down, all the way to the ground.

I was surprised that the third uncle's yard was not big, only six or seven square meters. There were four or five wires in the bundle, all running under the eaves of the wall. Only this one wire went underground.

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

The wires went all the way down to the manhole.

I never knew that my third uncle had this thing in his house. There was a handle on the manhole cover. I went up and lifted it, and found that I could lift it. It was dark inside, and my heart lifted.

There is a way.

I took a breath and said to my classmate: "Okay, just come here." After sending him away, I immediately went to the house to get a flashlight, came to the manhole cover, and took a deep breath. , pull it up and look down. To be continued
