Chapter 10 Under the Fence
Zhou Ziheng clearly felt the change in Xia Xiqing at the moment. Before, he looked like he was lazily staying out of the way. When he heard that a player broke through the room, he immediately officially entered the game.
But he also knew that Xia Xiqing didn't do this because he had a desire to win, he just wanted to leave here to watch the fun.
It may be his real purpose to make a puddle of muddy water more chaotic.
"Don't you think this poem is very strange?" Xia Xiqing turned a pen from nowhere, and drew a horizontal line on the last few lines of the poem.
[Only re-disassemble,
Return you to me, return me to you.
Connected to each other from top to bottom.
Everything can have meaning again. ]
He took out the note that was spelled out by Zhou Ziheng at the beginning, with a string of garbled characters written on the front, "I think this poem is implying the decoding method of this cipher."
Zhou Ziheng nodded in agreement, and read the poem carefully in his heart.
[We were once one.
Fate pulled you out of my body, from my bones, my flesh, my heart, and bluntly pieced together these meaningless organs.
I was buried with you, who was dismantled and rebuilt together.
Buried under this fence of lush roses.
Only by dismantling again,
Return you to me, return me to you.
Connected to each other from top to bottom.
Everything can have meaning again. ]
Once one, separated, pieced together, buried together one after the other...
He couldn't help but read it out in a deep voice: "Buried under this fence with lush roses..."
fence, fence...
Fence…
Suddenly, a flash of light flashed in my mind.
"Rail Fence Cipher."/"Rail Fence Cipher."
The two blurted out at the same time, and then looked at each other in surprise.
Xia Xiqing laughed first, "Looks like I'm really a fan of idols. I have a good understanding."
Zhou Ziheng sneered in his heart, sorry, he didn't want to be followed by such a person at all.
Having said that, Xia Xiqing's reaction speed still surprised him. "How do you know the fence password?" Zhou Ziheng asked.
Xia Xiqing replied casually, "My nephew is in IT, and for a while I studied a little bit of cryptography with him..."
Your nephew...? Zhou Ziheng frowned and looked at Xia Xiqing.
Where are you old goblin from?
He didn't say it, and didn't really believe what Xia Xiqing said. He leaned over and took the pen he found just now to prepare for decoding. Xia Xiqing turned the little poem to the other side and saw the words [2 you] written on it. , said with a smile, "Actually, the clues of the program team are really obvious. The 2 here is not to, it means that the original state of the password is divided into 2 columns, right."
"Well." Zhou Ziheng counted the long string of garbled digits with his hands, found the middle one, drew a vertical line, and disassembled them. Although he knew that Xia Xiqing understood the decoding process, in order to ensure the program The audience can also understand this process, Zhou Ziheng explained, "The first half of this poem is the encryption process, starting from 'only re-disassembly' is the prompt of the decoding process. According to the 2 written on the back, the garbled code Divide into two groups equally, each with seven letters."
PGOEUDE AENNHRD
"'Return you to me, return me to you' should mean dismantling and restoring the letters in the grouping." As he spoke, Zhou Ziheng re-transcribed the two separated groups, aligning the two lines.
PGOEUDE
AENNHRD
Zhou Ziheng lowered his head, reciting the penultimate line of the verse, "From top to bottom, connected to each other." Starting from the letter P in the first line, he drew lines with his strokes, first pointing to the A in the second line, and then As soon as the stroke of the pen is turned, the line revolves back to G, and so on, until this circuitous wavy line penetrates each letter and reaches the last letter D.
"Write it down in the order of the lines..." Zhou Ziheng half-bent over and carefully copied the final answer.
PAGEONEHUNDRED
Page one hundred.
"The hundredth page." Xia Xiqing picked up the unbelievably thick book next to him and turned to the hundredth page.
The entire page was printed with dense ants-like characters, and he saw four numbers on the forty-second line.
[I live only because of my desire, for this fiery cliff, if possible, at the moment when my desire burns out, I will be the 1414th rose in the sea of roses in your heart, no more, no less, Just do that one. ]
"1414." Xia Xiqing put down the book, walked to the front of the study, and entered the four numbers on the password lock screen on the door.
The combination lock glowed blue, flashed three times, and finally displayed a green prompt on the screen.
[The password is correct! ]
Xia Xiqing tried to push the door, only to hear a click, and the door lock was unlocked. Xia Xiqing, who originally wanted to slip away by himself, noticed the close-up on the door lock, so he smiled and turned to Zhou Ziheng and said, "We can go out, let's go."
Zhou Ziheng, who was leaning against the desk, gave him a meaningful look, and finally walked towards him with his hands in his coat pockets.
A new beep sounded from the audio.
[Note that two players are now escaping the original room and entering the other player's room. ]
"Is the alliance still established?" Zhou Ziheng suddenly said.
Xia Xiqing smiled and pushed open the door, "Of course, if my use value hasn't been drained."
The word "squeeze dry" was used so delicately that Zhou Ziheng didn't even feel that he was being molested by Xia Xiqing, so he followed him out of the primitive room unconsciously.
The structure of this house is very strange. There is no corridor-like partition between the rooms. Open the door of your own room and enter the new room directly. The people in the room were doing something, when they heard the wall behind him, at least he always thought that the door of the wall was suddenly opened, and he couldn't help but startled and his back shook.
Adhering to the original intention of shaping the character, Xia Xiqing took the initiative to greet the original owner of the room with a smile, "Hi, we are the players who escaped from our room just now. You should have received news from the program team."
The man was wearing a creamy yellow overcoat, and his hair dyed light brown looked very fluffy. Hearing the voice, he turned around, and the moment he saw Zhou Ziheng, his beautiful face suddenly showed a sigh of relief. With an expression, "Ah Ziheng, it's great, it's you." He smiled at Xia Xiqing again, "Hello, hello... Hey, aren't you the most recent one? The one on Weibo two days ago..."
Xia Xiqing reported himself very considerately, "Xia Xiqing." The other party looked like he was about to introduce himself, but Xia Xiqing immediately spoke for him, "Shang Sirui, I like your group's songs very much."
Shang Sirui is the face of the popular group HighFive. She has worked with him in a play before, but it's just a cameo role. Although Xia Xiqing was talking about scenes, and he didn't like to listen to the songs of such idol boy groups, their popularity among young people is still good, especially this Shang Sirui, with a handsome face He has become a popular top member of the group with a confused personality.
"Really?" Shang Sirui laughed twice, "Hey, you guys are amazing, you escaped so quickly, I messed around here for a long time and didn't come up with anything useful, hey, I'm surprised Well, why did my agent give me such a difficult announcement?"
Xia Xiqing almost didn't laugh out loud. He was also an idol after all. It was like talking about cross talk when he started talking. No wonder he was criticized by netizens.
"The two of you are always quicker." Zhou Ziheng walked over to Shang Sirui to check his current progress.
I don't think it's obvious until the two of them were standing together. Xia Xiqing realized that Zhou Ziheng was really tall, and his shoulders were wider than Shang Sirui's, which made Shang Sirui, who was originally above the standard figure of a boy group, become petite. If he remembered correctly, these two seem to have CPs.
The entertainment industry's general attack on people is honest and does not deceive me.
Although Shang Sirui and Zhou Ziheng have countless face powders, their good looks are two completely different styles. Shang Sirui's facial features are light and youthful, and he looks like a high school boy, while Zhou Ziheng is The full-bodied face and deep facial features were once mistaken for mixed blood.
For Xia Xiqing, of course, the latter is more energetic.
The author has something to say: popular science of cryptography:
In fact, I have tried my best to explain the decryption process in the simplest language (Zhou Ziheng's words). Many readers may have persuaded 2333 to quit after seeing the word [password], which is actually very interesting (really~). If you are interested, you can take a look at the following popular science (no math knowledge, it is a very simple operation)
The garbled code [PGOEUDEAENHNRD] that appeared in these two chapters belongs to a fence password that is divided into 2 columns. I will not mention the concept and use the password in the text as an example. The first half of the poem that appears in the text (I'm just calling it a poem) is the encryption process, so let's make a one-to-one correspondence.
We were once one. [The original clear code is Page one hundred, remove the spaces to become one PAGEONEHUNDRED]
Fate pulled you out of my body, from my bones, my flesh, my heart, and bluntly pieced together these meaningless organs. [How to "extract", because the column is 2, so it is divided into two groups, and it becomes PAGE ON EH UN DR ED, a total of seven groups (bones, flesh, heart, etc...) and then extract the first of each group. The first character (PGOEUDE) is placed in one pile, and the second character (AENHNRD) is placed in one pile, which becomes two piles]
I was buried with you, who was dismantled and rebuilt together. [Put together the two piles of letter sequences obtained just now, "one after the other", and you get the password PGOEUDEAENHNRD]
So this is the encryption method of the fence password. Similarly, let's take another example, such as encrypting "I Love You", if we encrypt it in 3 columns
First, remove the spaces into ILOVEYOU, then separate them into three or three, ILO VEY OU
Then the first letter of each part goes to the heap (IVO), the second letter goes to the heap (LEU), and the third letter goes to the heap (OY)
Finally put them together end to end: IVOLEUOY
Dangdangdang, encryption is complete! (Take it and confess it~)
Have you learned the fence password? In fact, it is very good to set the passwords of mobile phones and some accounts every day~
For the decoding pa
rt, follow the steps in the text, first divide the garbled characters into two columns, use a line to string together with wavy lines, and write them in order.
