Zhou Ziheng clearly felt the changes in Xia Xiqing at this moment. Before, he was lazily staying out of the matter, but when he heard that a player broke through the room, he immediately threw himself into the game.
But he also knew that Xia Xiqingâs behavior was not because of his desire to win, but because he wanted to leave here to watch the excitement.
To make the muddy water even more chaotic is probably his real purpose.
âDonât you think this poem is strange?â Xia Xiqing found a marker pen from somewhere, and drew a horizontal line on the last few lines of the poem.
Give you back to me, give me back to you.
From top to bottom, connected to each other.
Everything can regain meaning. ]
He took out the sticky note that Zhou Ziheng had spelled together at the beginning, with a string of garbled characters written on the front, âI think this poem hints at the decoding method of this code.â
Zhou Ziheng nodded in agreement, and read the poem carefully in his heart.
Destiny pulled you away from my body, from my bones, my flesh and my heart, and abruptly put these meaningless organs together.
I was buried together with you who were dismantled and reconstructed together.
Buried under this fence with lush roses.
Give you back to me, give me back to you.
From top to bottom, connected to each other.
Everything can regain meaning. ]
It used to be one body, separated, put together, buried together one after the otherâŚ
He couldnât help but read out in a deep voice: âBuried under this fence with lush rosesâŚâ
Suddenly, a flash of inspiration flashed in my mind.
âRailFenceCipher.â / âFenceCipher.â
The two blurted out at the same time, and then looked at each other in surprise.
Xia Xiqing laughed first, âIt seems that I am really an idol. I have a perfect understanding.â
Zhou Ziheng sneered in his heart, sorry, he didnât want to be followed by such a person at all.
Having said that, Xia Xiqingâs reaction speed still surprised him. âHow do you know the password for the fence?â Zhou Ziheng asked.
Xia Xiqing replied casually, âMy nephew is in IT, and I studied a little cryptography with him for a whileâŚâ
Your nephew� Zhou Ziheng frowned and looked at Xia Xiqing.
Where are you from, old goblin?
He didnât say anything, and didnât really believe what Xia Xiqing said. He leaned over and grabbed the pen he found just now to decode the code. Xia Xiqing turned the little poem to the other side and saw [2you] written on it, He smiled and said, âActually, the clues of the program group are really obvious. The 2 here is not to, it means that the original state of the password is divided into 2 columns, right?â
âEn.â Zhou Ziheng counted the long string of garbled digits with his fingers, 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, âThe first half of this poem is the process of encryption, and the beginning of âonly re-disassemblyâ is a reminder of the decoding process. According to the 2 written on the back, the garbled characters Evenly divided into two groups, with seven letters in each group.â
ââReturn you to me, return me to youâ should mean dismantling and restoring the letters in the group.â While speaking, Zhou Ziheng re-transcribed the two separated groups, aligning the two lines.
Zhou Ziheng lowered his head, and while reading the penultimate sentence in the poem, âFrom top to bottom, they are connected to each other.â Starting from the letter P in the first line, he drew a line with a pen, first pointing to the A in the second line, and then With a turn of the pen, the line loops back to the G, and so on, until the rippling line penetrates every letter and reaches the last letter D.
âWrite it down in the order of the linesâŚâ Zhou Ziheng half-bent down and carefully copied the final answer.
âThe hundredth page.â Xia Xiqing picked up the unbelievably thick book next to him, and turned to the hundredth page.
The entire page was printed with words that looked like ants, and he saw four numbers on the forty-second line.
[I only live 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 make that one. ]
â1414.â Xia Xiqing put down the book, walked to the front of the study, and entered these four numbers on the password lock screen on the door.
The combination lock glows blue, flashes three times, and finally displays a green message 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 shot on the door lock, so he turned around and said to Zhou Ziheng with a smile, âWe can go out now, letâs go.â
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 beep came from the speaker.
[Note that two players have now escaped from the original room and entered the other playerâs room. ]
âIs the alliance still established?â Zhou Ziheng asked suddenly.
Xia Xiqing smiled and pushed open the door, âOf course, if my use value has not been drained.â
The word squeezed out is so subtle that Zhou Ziheng didnât even feel that he was being molested by Xia Xiqing, and followed him out of the original 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 directly enter the new room. The people in the room were busy doing something, when they heard the wall behind them, at least he always thought it was the door of the wall being opened all of a sudden, he couldnât help being startled and his back trembled.
Adhering to the original intention of shaping the character design, Xia Xiqing took the initiative to greet the original owner of the room with a smile, âHi, we are the players who escaped from our room just now, you should have received a message from the program team.â
The man was wearing a creamy yellow overcoat, and his dyed light brown hair looked very fluffy. When he heard the voice, he turned around, and his pretty face suddenly showed a sigh of relief when he saw Zhou Ziheng. Facial expression, âAh Ziheng, great that itâs you.â He smiled at Xia Xiqing again, âHello, hello⌠Hey, arenât you the one who was recently? The one on Weibo two days agoâŚâ
Xia Xiqing reported his family name very considerately, âXia Xiqing.â The other party looked like he was about to introduce himself, and Xia Xiqing immediately spoke for him, âShang Sirui, I like the song of your group very much.â
Shang Sirui is the face of the popular group HighFive. Shang Sirui had worked with him in a movie before, but it was just a cameo role. Although Xia Xiqing only talks about scenes, and he doesnât like listening to the songs of this kind of idol boy group, but their popularity is still good in the circle of young people, especially this Shang Sirui, with his handsome face He and Yuâs confused personality has become a popular top member in the group.
âReally?â Shang Sirui laughed twice, âHey, you guys are amazing, you escaped so quickly, Iâve been tossing around here for a long time and havenât come up with anything useful, hey, Iâm surprised Now, why did my agent answer such a difficult announcement for me?â
Xia Xiqing almost didnât laugh out loud. Heâs an idol anyway, and when he opened his mouth, it was like talking about cross talk. No wonder the netizens complained about his mouth.
âThe two are always faster.â Zhou Ziheng walked to Shang Siruiâs side to check his current progress.
Xia Xiqing realized that Zhou Ziheng was really tall and his shoulders were wider than Shang Siruiâs when the two of them stood together, which made Shang Sirui, who was originally above the standard figure of the menâs team, look petite. If he remembers correctly, these two people seem to have a CP.
The general attacker in the entertainment circle pretends to be honest and does not deceive me.
Although both Shang Sirui and Zhou Ziheng have countless fans, their looks are completely different in two styles. Shang Siruiâs facial features are light and full of youthful looks, looking like a high school boy, while Zhou Ziheng is The full face and deep facial features were once mistaken for mixed blood.
For Xia Xiqing, of course, the latter is more exciting.
The author has something to say: Cryptography knowledge popularization:
In fact, I have tried my best to explain the decryption process in the simplest and easy-to-understand language (Zhou Zihengâs 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 popular science below (without mathematical knowledge, it is a very simple operation)
The garbled code [PGOEUDEAENHNRD] that appeared in these two chapters belongs to a fence password divided into 2 columns. I will not talk about the concept and use the password in the text as an example. The first half of the poem that appears in the article (I wrote it blindly, letâs call it Shi Ba) is the encryption process, so letâs make a one-to-one correspondence.
We were one. [The original plain code is Pageonehundred, remove the spaces to become one PAGEONEHUNDRED]
Destiny pulled you away from my body, from my bones, my flesh and my heart, and abruptly put these meaningless organs together. [How to âextractâ, because the column is 2, so divide it two by two to become PAGEONEHUNDRED, a total of seven groups (bones, flesh, heart, etcâŚ) and then extract the first character (PGOEUDE) of each group and put it in One pile, the second character (AENHNRD) is placed in one pile, it becomes two piles]
I was buried together with you who were dismantled and reconstructed together. [Put together the two piles of letter sequences obtained just now, âone in front and one in backâ, and you will get the password PGOEUDEAENHNRD]
So this is the encryption method of the fence password, and we will give another example, such as encrypting âILoveYouâ, if we encrypt in 3 columns
First remove the space to become ILOVEYOU, and then separate three by three, ILOVEYOU
Then the first letter of each part is grouped (IVO), the second letter is grouped (LEU), and the third letter is grouped (OY)
Finally put them together end to end: IVOLEUOY
Dangdangdang, the encryption is complete! (Take it to confess~)
Have you learned the fence code? In fact, the passwords used to set up mobile phones and some accounts every day are very good~
For the decoding part, follow the steps in the text, first divide the garbled characters into two columns, string them together with wavy lines on one line, and write them in order.
