"It is my great fortune to have Professor Hua's help. I never thought that an accidental idea would be of such great help to our anti-Japanese cause." Zhang Zizhong silently watched the two people who entered the study and waited. The door closed, and my mind recalled the story I heard about the British mathematician deciphering the code.
Two months ago, on his way home from work in Tianjin, Zhang Zizhong accidentally overheard a conversation between two students and learned about the story of a British mathematician who deciphered the German code.
After listening, Zhang Zizhong drew parallels and immediately came up with an idea. Since British mathematicians could decipher the German code, why didn't he find Chinese mathematicians to try to decipher the Japanese code system?
"That's exactly what the general said. If you hadn't come up with the idea, we wouldn't have known there was a way to decipher the Japanese code..." Tian Hong nodded with emotion.
"Let's wait for the good news. Don't disturb Professor Hua and Student Yu." Zhang Zizhong smiled, glanced at the closed light yellow door, and warned.
For Zhang Zizhong, the red secret deciphering project chaired by Hua Luogeng is the most concerning thing recently. In order to ensure the confidentiality of the entire project, Zhang Zizhong traveled extremely carefully and secretly to prevent his whereabouts from being discovered by interested people and Japanese spies, thereby exposing him. Project and Professor Hua Luogeng.
If the Blue Clothes Secret Service arranges top agents to steal Japanese military secrets, it is a small effort, then the red secret deciphering project carried out by Professor Hua Luogeng and Yu Hua is digging into the roots of the Japanese military.
Once successful, the benefits are almost unimaginable.
…
Facts always differ from plans, and plans can never keep up with changes.
Just as Yu Hua originally thought that the first batch of original plaintext data would be enough to decipher the true meaning of all letters in the red secret system, the final result failed to do so.
Hopefully the second batch of raw plaintext will have a large enough sample size of remaining letters.
After entering the study, Hua Luogeng and Yu Hua divided their work and cooperated. Yu Hua was responsible for the first 2,500 copies of the second batch of original plain texts, and Hua Luogeng was responsible for the last 1,000 copies of the second batch of original plain texts. Each of them carried out the deciphering work in an orderly manner in the most comfortable and accustomed way.
Sitting in front of Xintian's desk, with a cup of hot tea on his left hand, Yu Hua looked natural and opened the first original plain text with his right hand. He cast his eyes on the surface of the paper, read the content, and extracted all the different combinations on it that seemed extremely abstract and messy on the surface. English alphabet.
This original clear text from the Kwantung Army Headquarters in Xinjing has a lot of content, about 300 letters, and contains a lot of scarce remaining letters. The letters x and z appear frequently, 35 and 28 times respectively.
After reading it in one second, his eyes extracted all the letters like an electronic scanner and gathered them in his brain for storage. Yu Hua already had an idea in his mind and faintly analyzed the true meaning of the remaining letters. He quickly placed the first piece of original plain text with his left hand and took it with his right hand. Put the second original plain text in front of you.
Read, record, organize.
Like a decoding machine with no emotion, Yu Hua frantically recorded the content of the second batch of original plaintext data. The efficiency was so high that it was almost the same as a real machine. Hua Luogeng, who was sitting at another desk, saw Yu Hua's working status, and the corner of his mouth With a smile, he then continued his deciphering work.
In terms of mental arithmetic ability, his apprentice is definitely the best in the country.
The important thing is that Yu Hua, who particularly likes mental arithmetic, has not missed a single number so far. He has extraordinary talent and sensitivity in mathematics.
Research is unknown, and time passes quietly.
As Yu Hua used his unique research method to collect the original plain text content, more and more original English letters had not yet been analyzed and studied in his mind, and they soon exceeded 10,000 from 1,000 digits.
Fifty thousand people.
One hundred thousand people.
Two hundred thousand people.
Relying on the cooling and soothing effect of the golden mathematical symbols, Yu Hua worked extremely efficiently and stably. After just one and a half hours, all 2,500 pieces of original plaintext data were recorded and stored in his brain, bringing the total to 478,642 The position is huge.
Start parsing.
After collecting the second batch of 2,500 original plaintext data, Yu Hua took a deep breath, closed his eyes, and without hesitation controlled his brain to start working at full speed, entering the most important analysis step of the deciphering process.
The entire person quickly marks specific letters and letter combinations through the unique frequency analysis attack algorithm given by Hua Luogeng.
xzz……
zzky…
abzxd……
ahhdxx…
As time went by, more and more letters and letter combinations were listed one by one and specially classified. Yu Hua spent his brainpower maintaining more than 470,000 English letters while distractedly arranging and classifying various letter combinations, and then focused on analyzing them.
It's three uses at a time.
Now, Yu Hua has become an out-and-out humanoid computer, and his brain is performing horrific calculations and analytical deductions that ordinary people cannot imagine at all times.
An hour later.
Yu Hua suddenly opened his eyes, his eyes were shining with light, and his black pupils were like black holes, revealing a mysterious and vast meaning. His face was slightly pale, and his brain, which had been working at full capacity for more than an hour, was taking a rest. A feeling of fainting was acting on his head, and then Quickly offset by the golden mathematical symbol in the center of the mind.
"Huh..." Yu Hua exhaled a breath and relaxed his mind.
"Xiaohua, are you okay?" At this time, a gentle voice came over, and Hua Luogeng was standing in front of the desk, asking with concern on his face.
There were golden mathematical symbols to offset the feeling of fainting. Yu Hua, who was doing full-load calculations again, felt much better. He shook his head slightly and gave good news: "It's okay, Professor, I have deciphered all the last thirteen letters. These are English letters." matrix numbers."
After finishing speaking, he picked up the pencil in his right hand and quickly wrote the matrix numbers corresponding to the remaining five English letters on the scratch paper.
The second batch of original plaintext data contained so many remaining letter samples that Yu Hua was able to decipher all the last thirteen letters at once.
"Okay, I have deciphered the first thirteen letters. The total number of deciphered letters has reached 22, and there are four left. Now is the last moment of deciphering. You go out to announce the good news first, and then eat and rest. I am here Continue to decipher." Hua Luogeng looked happy, seeing that Yu Hua's face was indeed normal, he picked up the manuscript paper with the remaining English letters written on it in his right hand and arranged it.
The countdown to deciphering the twenty-six English letters of the red secret system has arrived.
Once all English letters are deciphered, the original matrix can be established, and Hua Luogeng can perform inverse matrix calculations and finally crack the red secret.
It can be said that this is the most critical and important moment of the entire work, and he cannot delay it at all.
"yes."
Yu Hua nodded in response, took a deep breath, and adjusted himself.
Get up and open the door.
It was getting late and the lights in the living room were bright. Zhang Zizhong and others sat on the sofa and closed their eyes to rest.
"Classmate Yu, how are you? Is there any news?" At this time, Zhang Zizhong, who was resting with his eyes closed, relied on his military sixth sense to keenly feel that someone was looking at him. He opened his eyes and saw Yu Hua standing at the door, and quickly got up. before, asked.
Tian Hong and Li Ping on the side noticed the movement, immediately woke up, and stood up one after another.
Why do I feel like I’m having a baby?
Seeing the three people reacting like this, Yu Hua suddenly felt like he was a doctor in the delivery room. The three people waiting for Hong Mi to decipher the news looked like the panicked and anxious family members of the mother outside the delivery room.
"It has been deciphered to the 22nd position, and there are 4 left. It has reached the final moment." Yu Hua shook off the weird thoughts in his mind, faced Zhang Zizhong and the others, and gave the current deciphering progress.
It has to be said that the progress of red secret deciphering is so fast that it is completely abnormal. It has reached the level of progress measured in hours. When conducting code deciphering abroad, the progress is slow and no progress is made. It is common to wait for several months and half a year.
"There are four left, which means that the results will be available at the earliest today and tomorrow at the latest, right?" Zhang Zizhong was startled, with a look of joy on his face, he thought and calculated for himself, and asked.
Tian Hong, the leader of the Peking team, and Li Ping, his assistant, held their breaths and stared at Yu Hua with expectant eyes.
Yu Hua nodded: "Almost..."
The time is correct, today is Friday and tomorrow is Saturday. He will take a break today and prepare to stay up late and work overtime to solve the last four letters at once.
Zhang Zizhong took a deep breath, turned around, and issued an order to Li Ping: "Major Li, tell the driver that I will stay here tonight. In addition, send a company of soldiers over to set up a security checkpoint at the west gate of Tsinghua Garden if there are any suspicious persons." Anyone who comes close will be killed."
At the end of the words, there was a hint of murderous intent.
"Yes!" Li Ping immediately straightened his back and raised his hands in salute.
