Originally, Xiao Yuan's thinking has been stuck in the isolated analysis of each sample, after trying various methods without success, he had to change his thinking, began to seek new methods, after trying several other methods, began to think of intercepting a few more sets of data, and then agreeing to the sampling rate of the data according to the time period composition sequence for longitudinal analysis.

After the longitudinal analysis was also fruitless, he put together the data of different sampling rates sampled in the same time period and conducted a horizontal analysis, but the horizontal analysis also did not yield any useful results.

"Are these waveforms inherently analog signals and have nothing to do with digital signals?" Xiao Yuan couldn't help but have such doubts, if it was really as he suspected, then all the efforts he had made before, including the programs he had written, would be useless.

Although Xiao Yuan knew very well that the probability of signal decryption failure was much greater than the probability of success, Tang Sa did not show up for a day made him very worried, and he helped Tang Sa decrypt the signal sent from this signal source as soon as possible, which was the only thing he could do for her now, so admitting failure made him very unwilling, and he would not give up because of this.

Since he is unwilling to give up, then he needs to find another way, the time has reached more than six o'clock in the evening, and he only eats one breakfast a day, but Xiao Yuan does not feel hungry at all, a day of high-intensity mental work, and staring at the CRT monitor of the computer for a long time, making his eyes sour and astringent, but he is not aware of these, his eyes are still staring at the computer screen, thinking about what method to continue to try next.

A moment later, he was going to copy the strings on paper again for analysis, but this time it was different from the last single analysis, and he was going to put the binary streams obtained at different sampling rates in the same cycle together for side-by-side analysis.

After copying down a binary string, when Xiao Yuan copied the second one, he copied more than a dozen binary bits, stopped, and temporarily put the content copied in front of him aside, but found a large white paper in the filing cabinet in the computer room, and copied the first string again, this time because the paper was long enough, he copied the entire binary string into a line, and then copied another one below, and aligned it with the previous digit from high to low, and so on.

Xiao Yuan copied all the binary strings collected in a cycle to the paper in a digitally aligned way, at this time, he was going to compare and analyze these characters, but when he glanced at the binary strings that were densely copied almost half of the paper, he was suddenly stunned, and the scene he saw in front of him made him think he was dazzled, so he rubbed it hard, and looked at it again, but finally determined that he was not dazzled, and then couldn't help but shout: "I see." ”

At this moment, on a large piece of paper, the dense number of bit-aligned strings is like a character painting, with the number 1 in all binary strings as the background, and the number 0 in this background forms a string of numbers: 03:13:55.

"What does this mean, it seems to be a time, is it a coincidence?" Xiao Yuan stared at the string of numbers and frowned.

"The probability of a coincidence is infinitely close to zero."

Xiao Yuan quickly made some calculations in his mind and made a judgment, "This time must represent some kind of special meaning." ”

At this time, Xiao Yuan felt extremely admired for the whimsy of this encryption method, according to people's mindset, almost no one could have thought that information could be stored in this way, including him Xiao Yuan, the reason why he was able to find out now was also completely by chance.

At the same time, Xiao Yuan also thought that this encryption method can actually be further expanded, if what is shown here is not time, but a certain coding method is used to form a matrix, and even add a time dimension to these matrices to form an encoding sequence, then the amount of data contained in it can be further expanded, and its storage capacity can even increase exponentially......

"It's amazing, it's worth looking into."

Xiao Yuan suddenly felt a little excited, and his mind was thinking about it for a while, but at this moment, it was not a matter of thinking deeply about this problem, he had to find the meaning of this time as soon as possible, so he had to press the one in his heart, and found another set of data, this time in order to save time, he no longer copied it on the paper, but used a software to arrange it neatly in the above order, and sure enough, there was another time string, but the time value was different from just now, this time it was 02:27:44, and the time was reduced.

After analyzing several sets of data one after another, Xiao Yuan got several time values, compared these time values with the data stream sampling time, and found that these times were a few moments in a countdown, and he calculated the time when the countdown returned to zero: 20:00, and there was still more than an hour left.

"What the hell is this countdown for?" Xiao Yuan was a little puzzled, but intuitively he felt that something big should happen when the time was zero, "What will happen after the countdown ends?" ”

Xiao Yuan flashed several possibilities in his mind, because Tang Sa did not appear for a day to cause him psychological effects, none of these possibilities was a good thing, the most serious thing was that he actually thought of a time bomb, or a major action taken by the Xinhua Yi Gang against Tang Sa......

Thinking of these bad things, Xiao Yuan looked at the time again, there was only a little more than an hour left, and he couldn't sit still, and wanted to urgently spread the news from here.

"What should I do, I'm not afraid of 10,000, I'm afraid of what happens, but what happened outside, Sister Sa will lock me in here and don't let me out, I'm really anxious." Xiao Yuan got up from his seat and walked back and forth in the room a few times, his mood becoming extremely agitated.

"What should I do?" Xiao Yuan asked himself several times, and he was as anxious as an ant on a hot pot in the room, and before he knew it, the time was spent by Lang for more than ten minutes, and there was less than an hour left before it was zero.

Ding Dong, the computer sent out a prompt, pulling him back from his anxious state, he sat back next to the computer, and found that it was Jessica who sent him a greeting online: "I attended an academic conference in the afternoon, not in the laboratory, do you have anything to do with me?" ”

"That's done, thank you, Jessica." Xiao Yuan replied, because he had something in his heart, so he was a little absent-minded.

"Didn't help you, sorry, are you in San Francisco now?" Because of the Internet, it is impossible for Jessica to know that Xiao Yuan is not in the mood to talk to her at the moment, probably because she found out that his current IP address is from San Francisco, so she asked.

"Yes, I have something to do in San Francisco, and I originally wanted you to help me tell Yingying, but you weren't here, so I asked Han Xiaoyu to help me." Xiao Yuan replied.

"Did Han Xiaoyu help you pass the word, I saw Yingying this afternoon, and she was still saying that she couldn't contact you, and she didn't eat the lunch she was worried about for you." Jessica replied to Xiao Yuan with a message that surprised him, which also made his mood instantly more irritable.

"Han Xiaoyu obviously promised me, didn't he go to find Yingying, ****, damn it." As a result, Xiao Yuan's words in reply also became irritable, and even burst into foul language.

Jessica didn't reply to Xiao Yuan immediately, so that Xiao Yuan thought that she was frightened by her own rudeness, which reminded him that he was indeed a little not calm just now, so he calmed down his emotions and wrote another message to Jessica: "I'm sorry, I'm in a lot of trouble, I'm in a bad mood, I shouldn't have said what I just said to you." ”

"It's okay, you misunderstood, I called Han Xiaoyu and asked, after you sent him a message, Tang Xinxin looked for him, he forgot about what you asked him to do, this guy is really unreliable, I have already criticized him for you, he is now going to Yingying to help you pass the word." Jessica said.

"Thank you, Jessica." Hearing Jessica say that Han Xiaoyu had left behind what he had repeatedly told him so easily, he couldn't help but want to get angry again, so he quickly took two deep breaths again, tried to calm down his emotions, and thanked Jessica.

"No thanks, what trouble are you in and do you need my help?" Jessica asked.

Seeing Jessica offer to help him, Xiao Yuan did not refuse, muttered for a while, and replied: "Jessica, I ask you to go to Yingying in person, let her go home immediately, and when you get home, open the Compaq notebook and connect it to the Internet, I have something important to find her." ”

"Okay, I'll go now." Jessica said.

"Remember, be quick, there's not much time left for me." Xiao Yuan looked at his watch, and before he knew it, almost ten minutes had passed, so he said.

"Okay, I'll drive Yingying home." Jessica said.

"Thank you, go ahead, I'll wait here." Xiao Yuan said.

Jessica didn't reply to Xiao Yuan, and soon Xiao Yuan saw that her status had become offline, and she should have left the laboratory to find Xia Jiuying, so he turned on a network scanner and began to constantly probe the IP address of his home computer.

After about ten minutes, Berkeley's home computer came online, so he logged into the computer through his pre-set back door, established a conversation process on it, and sent a message: "Yingying, is that you?" ”

About ten seconds after the message was sent, a message replied: "It's me, I'm with Jessica, I heard Jessica say that you are in trouble in San Francisco, what is going on?" ”

Xiao Yuan was stunned for a moment, and then wrote: "Yingying, you let Jessica talk to me, you go to find the master, the matter is urgent, and I will explain to you when the matter is resolved." ”

"Okay." Xia Jiuying replied, and then another message replied: "I'm Jessica, what do you need me to do?" ”

Xiao Yuan hesitated for a moment, and then wrote a message over: "Jessica, can I trust you?" ”

ps: It's been a long time for the past two days, and the update is a little abnormal, sorry, it should be better tomorrow.
