Several people are wandering around the computing network, with data flowing up, down, left and right. "What do these numbers mean?" Liu Mozhi asked.
"Let's think about it one by one. Let me start with, is it ASCII code? It is a computer coding system based on the Latin alphabet, mainly used to display modern English and other Western European languages. It is the most common information exchange standard. To A total of 128 characters have been defined so far. 0~31 and 127 (33 in total) are control characters or communication-specific characters (the rest are displayable characters), such as control characters: LF (line feed), CR (carriage return), FF (page change), DEL (delete), BS (backspace), BEL (ring), etc.; communication special characters: SOH (head of text), EOT (end of text), ACK (confirmation), etc. 32 to 126 (total 95) are characters (32 are spaces), of which 48 to 57 are the ten Arabic numerals from 0 to 9. 65 to 90 are 26 uppercase English letters, 97 to 122 are 26 lowercase English letters, and the rest are some punctuation marks , operation symbols, etc. Its highest bit (b7) is used as a parity bit. The so-called parity check refers to a method used to check whether errors occur during code transmission. The 8th bit of each character is allowed to be Used to identify additional 128 special symbol characters, foreign language letters and graphic symbols."
"The numbers recognized by the computer are 0 and 1. The numbers we can see here are not just 0 and 1, but 0-9. In other words, the numbers we see have been converted."
"After converting it using ASCII code rules, it doesn't make sense. It's not English."
"How about using Morse code to convert it? Morse code is a bit more useful." "Heheng"-" is used to represent numbers and letters, and pauses are used to represent different words and sentences.". "Pronounced as "dip", it is a short dot signal, "-" is pronounced as "dah", which is a long signal that lasts for a period of time. Memorizing numbers is very easy, 5 "dah" is 0, add "dip" from the front " is added from 1 to 5, and adding "Di" from the end is reduced from 9 to 5. Between characters, it is represented by a dead time of 3 "Di"s, and between words, it is represented by a dead time of 7 "Di"s. Characters The password can be found by looking at the pattern of letters.”
"After converting it using Morse code rules, it doesn't make sense. It's not English."
"How to find the pattern of these numbers? Is it a string of numbers generated by yourself? For example, the next number is twice the previous number, and the next number is the previous number plus 1. I am giving a simple example, It is also possible that the latter number is 22 times the previous number, or the latter number is the previous number plus 111. It is possible that the latter number is 3x times the previous number, or the latter number is the previous number plus 3y. Multiples and additions The numbers change according to certain rules.”
"I don't see any pattern."
"Does the sum of the numbers before and after equal the value calculated using a formula, or according to the prime number table?"
"I don't see any pattern."
"We are simply looking at a meteor shower. A digital rain, or a digital river. But we don't understand what it is. What information are these being provided to us."
"Are these some kind of encrypted data? Qi Ao, I will transmit the data to you, and you can check it using various decryption methods."
"Okay, how do you want to transmit it?"
"There are cameras and tape recorders here. Data can always be transmitted."
"We can hear your voice. Otherwise, just read a string of numbers..."
"Using such a primitive method? Okay, I'll read it, and you can remember it."
Dong Chu read for 5 minutes. There are 300 numbers. Qi Ao used some methods to decrypt but did not see any useful information.
"If you do this, the amount of data is too small. There is no way to verify it. Think of a way to transmit a large amount of data."
"How to spread it? With images, we see different things. With sounds, we hear different things. How to spread it?"
"Use brain waves. The numbers you see, we convert the brain waves into numbers."
"Below is a larger amount of data. It's like a lake. The data on the way here is like a river."
"Yeah. Like historical data."
"It seems that historical data can be queried here."
"Let's go in and take a look."
"Encountered the guard program again."
"Is there a glasses tool here?"
"Yes, it's in the kit."
"It's the same as the glasses we bought. It seems to be related to the computing network."
"Find out the glasses tool code. It turns object information into numbers, and we turn the numbers into object form."
"The glasses are a transcode, a way of encoding."
"What can this do?"
"Find the traffic image. Find the larger traffic record. Find the network address."
"Converting. In progress... OK."
The originally transmitted numbers turned into images. You can see the shape of the data flow, find the historical records, and follow the clues to find the network address.
But it was found that this network address is virtual. A conversion may also be required.
"How to use this voice?"
"Separate the sounds of different frequencies. Then look at the amplitude and so on."
"Discover that, every once in a while, sounds have a common value."
"Is it similar to the picture? There is an enter key at the end of each line."
"Then process it and turn it into a picture."
"Yes, find the sound in the middle frequency, and the amplitude corresponds to the numerical value. Turn it into a picture."
"So clever. Switch with glasses."
"Okay. Conversion in progress. Done. Virtual address found real address."
Liu Mozhi said: "The person who made these glasses must be very good."
Zhan Guyue said: "The glasses for calculating the world are just a conversion method and a coding method. It does not require very deep mathematical knowledge. Making this glasses program does not require strong mathematical skills. The answer is solved because the creator Setting up questions and answers does not mean that he is very profound. You can also set up a coding method that makes it difficult for others to guess without telling others."
Dong Chu: "It makes sense."
Qi Ao: "Let's see what the final number is?"
A string of numbers appeared on the chess computer. There are several English letters HELP in the following content.
"What does it mean?"
"Did Mr. Tang send a distress signal? What happened to him?"
