Chapter 100 Cracking the Ciphertext
The night always falls quickly in winter.
A heavy snow fell, covering the ground with a silver blanket.
In a small closed room, Gu Xia was alone at the desk.
In front of him was a box of documents found in the lair of the Origin Cult, which seemed to contain letters, documents and books.
Gu Xia was trying to decipher the ciphertext on it, or rather, Xingchen was deciphering it, while he was reading a strange novel.
"Another story about a poor scholar and a fox fairy.
The Zhuxie Division is responsible for removing demons. If I can catch a real fox fairy in the future, I will definitely ask them if they like poor scholars."
He read the novel for a long time before he put the book down and stretched his body.
Gu Xia opened the virtual page and took a look. Xingchen showed that it was being deciphered.
Because he had no idea about the encryption method and no key, he could only use brute force to crack it normally. The amount of calculation was very large, and no one knew how long it would take.
However, Xingchen's cracking was a little different. Rather than cracking it, it was more like playing a word guessing game.
Because any language and encryption method is not irregular, each word or unit in the sentence has a relatively fixed semantics, and the grammar generally has rules to follow.
Xingchen's decryption is based on this.
For example, the first sentence on the paper is "123".
Xingchen assumes that "123" is equal to "Who are you".
Then split "123" into 1, 2, and 3, and substitute them into the places where these three units 123 appear in other texts for deduction and simulation.
If the semantics of the simulated article are smooth, reasonable, and consistent with the facts, it means that the decryption is successful.
If the simulated article is like garbled text, it means that the decryption failed.
Of course, guessing the semantic part of the sentence "123" is not a random guess.
Instead, it is based on the frequency of commonly used words and words in the articles analyzed in the Xingchen database.
Just like the word "的" appears in about 2% of the articles, a symbol that appears in the ciphertext with a frequency of 2% may represent the word "的".
If the Origin Demon Cult does not use Dagan language for internal communication, but uses other languages, there are other language data entered by Gu Xia in the internal database of Xingchen. As long as it is not a very rare language, you can try to simulate it.
This kind of "guessing word puzzle" game is unimaginable to humans. Only Xingchen can do it by using computing power to perform huge calculations.
...
In the blink of an eye, ten days passed quickly.
During this period, Gaoguan County also returned to peace.
But it was only a superficial tranquility.
The monsters, assassins, and massacres on the streets during the day, and then the soldiers in armor also blocked the entrances and exits of the county town. The patrolling yamen runners and constables from time to time made everyone realize that the county was no longer as peaceful as before.
In the county government, as expected, the county magistrate Qi and the wealthy merchants of Gaoguan County opposed the people of the Zhuxie Division to leave at this moment.
Yu Wusi, who received countless bribes, couldn't pull his face and left toughly. Moreover, he was confident of his strong martial arts, and he also had trump cards and life-saving methods on him, so he was not afraid of the Origin Cult.
He agreed to stay and protect the county government until the reinforcements arrived.
However, it was limited to the county government, and other areas were left to fend for themselves.
As for the purpose of investigating the Origin Cult, Yu Wusi looked at his subordinates, who were less than half left, and didn't think about it at all.
He thought that if County Magistrate Qi asked him to investigate again, at most he would spit out some silver.
Of course, after experiencing the attack on the county government, County Magistrate Qi had no more ideas.
That evening, Xingchen finally sent a prompt that the decryption was completed.
It was not decryption, but Xingchen guessed the true meaning of these symbols through repeated simulations.
Gu Xia put down the book in his hand, opened the virtual panel, glanced at a few pages of the decrypted documents, and compared them with the original manuscript.
"The encryption is very cautious!"
He discovered that the encryption method of the Origin Demon Cult was unexpectedly complicated. Not only were all the words replaced by symbols, but there were also interference items. One out of every four symbols was meaningless.
Even the position of the meaningless interference items was not fixed. It can only be said that the people who designed the code of the Origin Demon Cult were very cautious.
If it were an ordinary person, it would be basically impossible to obtain valuable intelligence after seizing the documents.
However, this encryption method made the Origin Demon Cult very confident, so they kept many files in text form.
Xingchen showed that the coupling rate between the results of the calculation simulation and the original text was expected to be 99.99%.
As for why it is not 100%, it is because AI strictly follows the rules, and the Origin Demon Cult believers who write the ciphertext by hand may have some typos.
Gu Xia examined the pages of deciphered ciphertext.
"This is it!"
His eyes condensed, and he quickly took a pen to copy some of the information on it on paper.
Half an hour later, Gu Xia walked out of the room with a stack of papers.
"Lord Zhuxieshi, I have fulfilled my mission and cracked the Origin Demon Cult's documents."
"Really?"
Yu Wusi and other members of Zhuxie Division all looked at him in surprise.
"Look!"
Gu Xia handed over the original text and the translation, and also marked the encryption method translated by Xingchen, and summarized the words represented by some commonly used symbols into a table.
Yu Wusi took a look and followed the above method to randomly find a page of documents and decrypt it.
Then he showed a happy expression: "It's true! Gu Xia didn't expect you to have such a skill!"
Gu Xia said modestly: "It's nothing, just some side skills I learned before. Sir, please take a look at the contents of these two letters."
"This is..."
Yu Wusi took the two pages of paper and took a look.
One page of the content above is a transfer order, and the other page is a "transfer record".
"List of believers' donations:
Mr. Wu: 5,000 taels of silver
Mr. Yan: 300 taels of gold
Mr. Zhang: 2,000 taels of silver
..."
This page of paper records a string of seven or eight names of Gaoguan County gentry and wealthy businessmen, and even the name of the previous county magistrate.
They donated a total of 20,000 taels of silver to the Origin Demon Cult, and judging from the time, this record is from this month.
"No wonder the Origin Demon Cult can grow and develop in Gaoguan County, and there is no clue!
It turns out that someone is secretly colluding and sheltering the cult! And they are also funding them with huge sums of money to make them prosperous!"
Yu Wusi said angrily.
"Give this list to County Magistrate Qi and let him catch people himself!"
Gu Xia: "Sir, don't make it public yet. The county has set up the Origin Cult's spies, and we should take it slowly."
"That makes sense."
Yu Wusi looked at the record of the transfer order again, and the content was very simple.
"Xie Yue Si Yu, I now order you to lead two-thirds of your people to Xianfu City as soon as possible."
Then there are the follow-up personnel arrangements of the Gaoguan County branch of the Origin Demon Cult, which is what Xie Yue Si Yu said to his subordinates who stayed in the county.
"I will leave temporarily, and Dong Bai will take over my position now. You must obey his orders and continue the great plan of the Holy Cult."
Yu Wu Si was immediately shocked and said, "What! A large number of believers of the Origin Demon Cult went to Xianfu City?"
The time of this transfer order was nearly five months ago, which means that the two-thirds of the evil believers mentioned above had entered the city long before the demon-killing team came.
