"Hmm......"

Hearing Lin Cheng's words, Bai Ling couldn't help frowning slightly, indeed, since they went down to this underground base, they had been guessing what this place was for, and what they saw and heard along the way made them gradually realize that this was very likely to be an underground mine that was abandoned at some point, but until now they have not found where to enter the abandoned mine.

"Ever since I entered here, I've always had an inexplicable feeling that the parts we see about this underground base are incomplete, it seems that some important parts have been deliberately hidden, and it seems that this place experienced an earthquake a long time ago, so that the details that might have given us clues have also disappeared with the earthquake, and if it weren't for the cracks in the walls outside, maybe it wouldn't be easy for us to get into this office, let alone study the location of the mine here."

Shaking his head, this feeling of being kept in the dark is not comfortable, but Lin Cheng and they belong to outsiders after all, and it is not them that the owner of this underground base wants to guard against, but after so long, except for those giant rats, they have become the first humans to visit here.

"W-smack!"

Raising the Soul Breaking Sword in his hand and swiping it lightly, the wire between the wall and the iron table was instantly cut off, and with the impact of the iron table falling to the ground, Lin Cheng waved the dust that was waving between his nose casually, and then walked to the wall, picked up the wire that fell to the ground and looked at it carefully.

After a few glances, Lin Cheng's brows suddenly frowned, in order to confirm the guess in his heart, he saw him casually return the Soul Breaking Sword to the sheath, and at the same time pulled out the black jade dagger from his waist and slashed it hard in the middle of the wire, and saw two wires, one red and one black, directly scattered.

Squatting on the ground and picking up these two wires and observing them carefully for a while, he saw that the corners of Lin Cheng's mouth suddenly curled, and he shook his head while muttering in a low voice: "I see, I didn't expect that there was a lot of things in such a wire......"

"What's wrong?"

Bai Ling had been standing beside Lin Cheng, and after hearing his words at this time, his heart moved, and he hurriedly squatted down and asked.

"Whew-"

Seeing Bai Ling's curiosity, Lin Cheng didn't hide it from her, and directly held up the red wire in front of her eyes and said: "I originally thought that this black wire was all used for electrification, but you look at this red wire, although I don't know much about circuits, I also know that this red wire is enough for power, and the other black wire——"

Speaking of this, Lin Cheng picked up the black thread hanging on the ground again, pointed to the stubble inside the rubber and said slightly: "Look at this, you may not have seen this thing yet, but as long as people who have lived in peacetime should know more or less, this is a network cable!" ”

"Ethernet cable? What is it for? ”

Hearing this, a trace of confusion flashed in Bai Ling's eyes, after all, for her who woke up in the last days, the Internet is already a legendary thing, not to mention seeing it, it is estimated that she has not even heard of it.

Frowning and thinking for a moment, Lin Cheng tried to explain to her: "The network cable is a kind of communication line that is extremely popular in peacetime, and its use is probably similar to that of wires, but the wires are used to use electricity, and the network cables, as the name suggests, are used to connect to the network!" It's hard for me to explain this thing to you for a while, in short, you just need to understand that the appearance of this network cable is basically telling us that this can't be an ore base at all! ”

Seeing that Lin Cheng said with a determined face, Bai Ling looked stunned, and asked very puzzledly: "Why...... Why? ”

At this moment, Peter, who had been listening for a long time, took over, "Because although the emergence of the Internet can be traced back to the sixties of the last century, its commercial use and large-scale popularization were after the nineties, although we can't determine the specific age of this underground base, but judging from the cement passage outside and the dormitory structures on both sides, it is definitely impossible to build after the nineties......

"Yo? I can't imagine that you are not young, but you know so much about the Internet? ”

Hearing Peter's explanation, Lin Cheng glanced at him with some surprise, after all, according to the era of Peter's retreat, he should have come to this city to retreat in the late nineties, and the popularity of the Internet at that time is not very developed now, and middle-aged people like Peter have little understanding of the Internet at that time.

Listening to Lin Cheng's teasing, Peter shook his head helplessly, and said, "You have to understand, although I am not young, I also spent more than twenty years in the army before I went into hiding, and I am still a signal soldier!" So the Internet is not new to me, when most people don't even know about the existence of the Internet, I have begun to use the army's local area network to convey information, understand, young people? ”

"Okay, okay."

Hearing Peter's explanation, especially seeing the other party's expression a little unhappy, Lin Cheng smiled and waved his hand and said, "Uncle Peter, don't be angry, I just said it casually, why are you still angry?" ”

"Humph! Young people nowadays really don't know how to respect the elderly......"

Seeing that Lin Cheng softened, Peter snorted proudly, and then continued with the topic just now: "I just said, since this underground base was built before the nineties, if it is really an ore base, is it necessary to engage in a local area network that was extremely extravagant in that era and at the same time did not have much effect on their work?" So what Lin Cheng said is right, the appearance of this network line has fully explained one thing, this underground base cannot be an ore base at all, but should be used for other purposes! ”

Nodding, Lin Cheng stood up and lit a cigarette, and after taking two puffs, he said slowly: "Then again, Uncle Peter, what kind of organization do you think would spend a lot of money to build a LAN in such an underground base in that era?" In my opinion, except for state-level secret agencies, those ordinary institutions and companies don't need this stuff at all. ”

Hearing Lin Cheng's words, Peter couldn't help but light a cigarette, swallowing the clouds and spitting out the fog, he saw that his brows were already furrowed high, the appearance of this network cable had made him realize that his previous thoughts were completely wrong, "It's hard to say, but no matter what, this underground base is definitely much more mysterious than we imagined, no matter what we want to do next, we must be in good spirits......"

Seeing that Peter was also helpless about the current situation, Lin Cheng couldn't help frowning, as the investigation deepened, he felt more and more the strangeness of this underground base, I really don't know if if he kept investigating like this, would he encounter a more dangerous situation than those giant rats......
