    Chapter 10 Under the Fence

    Zhou Ziheng clearly felt the change in Xia Xiqing at this moment. Before, he was still lazy and aloof. As soon as he heard that a player broke into the room, he immediately officially joined the game.

    But he also knew that Xia Xiqing was not acting like this because he had a desire to win, he just wanted to leave here and watch the fun.

    To make a puddle of muddy water more chaotic is probably the real purpose of he.

    “Don’t you think this poem is strange?” Xia Xiqing found a pen from somewhere and underlined the last few lines of the poem.

    [Only re-disassembly,

    Give you back to me, give me back to you.

    From top to bottom, they are connected to each other.

    Everything can have meaning again.]

    He took out the note that Zhou Ziheng had put together at the beginning, with a string of garbled characters written on the front, “I think this poem is hinting at the decoding method of this code.”

    Zhou Ziheng nodded in agreement and read the poem carefully in his mind.

    [We were one.

    Destiny pulled you away from my body, from my bones, my flesh and blood, and my heart, and stiffly pieced together these meaningless organs.

    They were buried together with you who were torn apart and rebuilt together.

    Buried under this fence with lush roses.

    Only by disassembling it again,

    Give you back to me, give me back to you.

    From top to bottom, they are connected to each other.

    Everything can have meaning again.]

    They were once one, separated, pieced together, and buried together one after the other…

    he couldn’t help but read out loud: “Buried under this fence with lush roses…”

    Fence, fence…

    Fence…

    Suddenly, a flash of inspiration flashed in my mind.

    “Rail Fence Cipher.”/”Rail Fence Cipher.”

    The two of them blurted out the words at the same time, and then looked at each other in surprise.

    Xia Xiqing laughed first, “It seems that I am really a follower of idols. We have a perfect tacit understanding.”

    Zhou Ziheng sneered in his heart, I’m sorry, he doesn’t want to be followed by this kind of person at all.

    Having said that, Xia Xiqing’s reaction speed still surprised him.”How do you know the password for the fence?” Zhou Ziheng asked.

    Xia Xiqing replied casually, “My nephew works in IT, and he and I studied some cryptography together for a while…”

    Your nephew…?Zhou Ziheng frowned and looked at Xia Xiqing.

    Where did you come from, old goblin?

    He didn’t say anything, and didn’t really believe what Xia Xiqing said. He leaned over and took the pen that he had found just now and prepared to decode. Xia Xiqing turned the little poem to the other side and saw [2 you] written on it. He smiled and said, “Actually, the clues from the program team are really obvious. The 2 here is not to, but it means that the original state of the password was divided into two columns, right.”

    “Yeah.” Zhou Ziheng counted the digits in the long string of garbled codes with his fingers, found the middle one, drew a vertical line, and disassembled them. Although he knew that Xia Xiqing understood the decoding process, he wanted to ensure that the audience of the show could understand this.Zhou Ziheng explained the process, “The first half of this poem is the encryption process, starting with ‘Only re-dismantling’ is a reminder of the decoding process. According to the 2 written on the back, the garbled code is evenly divided into two groups, each with seven letters.”

    PGOEUDE AENHNRD

    “‘Return you to me, return me to you’ should refer to dismantling and restoring the letters in the group.” As he spoke, Zhou Ziheng re-transcribed the two separated groups, aligning the two lines.

    PGOEUDE

    AENHNRD

    Zhou Ziheng lowered his head and recited the penultimate sentence of the poem, “From top to bottom, connected to each other.” Starting from the P letter in the first line, he traced the line with the pen, first pointing to the A in the second line, and then turning the pen, the line circled back to G, and so on, until this circuitous line like ripples penetrated each letter and reached the last letter D.

    “Write it down in the order of the lines…” Zhou Ziheng leaned over and carefully copied the final answer.

    PAGEONEHUNDRED

    Page one hundred.

    “Page 100.” Xia Xiqing picked up the incredibly thick book next to him and turned to page 100.

    The entire page was printed with words as densely packed as ants, and he saw four numbers on line 42.

    [I only live because of my desire, for this fiery cliff. If I can, 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 that one.]

    “1414.” Xia Xiqing put down the book, walked to the study, and entered these four numbers into the password lock screen on the door.

    The combination lock emits a blue light, flashes three times, and finally displays a green prompt message on the screen.

    [Password is correct!]

    Xia Xiqing tried to push the door, only to hear a click, and the door lock was indeed unlocked.Xia Xiqing, who originally wanted to sneak away alone, noticed the close-up on the door lock, so he turned back to Zhou Ziheng with a smile and said, “We can go out, let’s go.”

    Zhou Ziheng, who was leaning against the desk, gave him a meaningful look, and finally put his hands in his coat pockets and walked towards him.

    A new tone came from the stereo.

    [Note that two players now escape the original room and enter their he player room.]

    “Is the alliance still established?” Zhou Ziheng suddenly said.

    Xia Xiqing smiled and opened the door, “Of course, if my use value has not been squeezed out.”

    The word “squeeze dry” was really subtle. It was so subtle that Zhou Ziheng didn’t even feel that he was being teased by Xia Xiqing, and followed him out of the original room without realizing it.

    The structure of this house is very strange. There is no corridor-like partition between rooms. You open the door of your own room and directly enter the new room.The people in the room were immersed in something when they heard the wall behind them, or at least the door that he had always thought was the wall, suddenly opened. They were startled and their backs 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 just escaped from our room. You should have received news from the program team.”

    The man was wearing a cream-yellow wide sweater, and his hair was dyed light brown and looked very fluffy. He turned around when he heard the voice, and his good-looking face suddenly showed an expression of relief when he saw Zhou Ziheng. “Ah Ziheng, great that it’s you.” He smiled at Xia Xiqing again, “Hello, hello… Hey, aren’t you the one recently? The one on Weibo two days ago…”

    Xia Xiqing introduced himself 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 frontman of the popular group HighFive. He has worked with him in a movie before, but it was just a guest role.Although Xia Xiqing only talks about the scene and doesn’t like listening to the songs of this kind of idol boy group, their popularity is still good in the circle of young people, especially Shang Sirui, who has become the most popular member of the group with his handsome face and confused personality.

    “Really?” Shang Sirui laughed twice, “Hey, you guys are so awesome. You escaped so quickly. I’ve been messing around here for most of the day and haven’t come up with anything useful. Hey, I’m surprised. Why did my agent give me such a difficult announcement?”

    Xia Xiqing almost didn’t laugh out loud. After all, he was an idol. When he opened his mouth, it was like talking about cross talk. No wonder netizens complained about his crisp mouth.

    “Two people are always faster.” Zhou Ziheng walked to Shang Sirui’s side to check on his current progress.

    Without comparing, Xia Xiqing discovered that Zhou Ziheng was really tall and had wider shoulders than Shang Sirui when they stood together, making Shang Sirui, who was originally above the boy band’s standard figure, look petite.If he remembers correctly, these two people seem to have CP.

    The entertainment industry’s general attack character is honest and does not deceive me.

    Although both Shang Sirui and Zhou Ziheng have countless fans, their good-looking styles are completely different. Shang Sirui’s facial features are light and boyish, looking like a high school boy, while Zhou Ziheng’s face is full of face, and his deep facial features were once mistaken for mixed race.

    For Xia Xiqing, of course the latter is more exciting.

    The author has something to say: popularization of cryptography knowledge:

    In fact, I have tried my best to explain the decryption process in the simplest and most understandable language (Zhou Ziheng’s words). Many readers may have dismissed 2333 when they saw 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, just a very simple operation)

    The garbled code [PGOEUDEAENHNRD] that appears in these two chapters belongs to a fence password divided into two columns. I will not explain the concept and just use the password in the text as an example.The first half of the poem that appears in the article (let’s call it Shiba that I wrote blindly) is the encryption process. Let’s correspond one by one.

    We were one.[The original clear code is Page one hundred, remove the spaces and become PAGEONEHUNDRED]

    Destiny pulled you away from my body, from my bones, my flesh and blood, and my heart, and stiffly pieced together these meaningless organs.[How to “extract”? Because the column is 2, so divide it into two and become PA GE ON EH UN DR ED. There are seven groups in total (bones, flesh and blood, heart, etc…) and then extract the first character (PGOEUDE) of each group and put it in one pile, and the second character (AENHNRD) in one pile, so it becomes two piles]

    They were buried together with you who were torn apart and rebuilt together.[Put together the two piles of letter sequences you just got, “one in front and one in the back”, and you will get the password PGOEUDEAENHNRD]

    So this is how the fence password is encrypted. Similarly, let’s take another example, such as encrypting “I Love You”. If we encrypt in three columns

    First remove the spaces to become ILOVEYOU, then separate three and three, ILO VEY OU

    Then the first letter of each part is stacked (IVO), the second letter is stacked (LEU), and the third letter is stacked (OY)

    Finally, put he together end to end: IVOLEUOY

    Dang Dang Dang, the encryption is completed!(Take it to confess~)

    Have you learned the fence code?In fact, the passwords for setting up mobile phones and some accounts are very good for daily use~

    For the decoding part, follow the steps in the article. First divide the garbled characters into two columns, string them up and down with a wavy line, and write them in order.
