Chapter 123 Countdown to the Red Secret Deciphering!
"It's really a blessing for my 29th Army to get the help of Professor Hua. I never thought that a random idea at the beginning would be of such great help to our anti-Japanese cause." Zhang Zizhong watched the two people entering the study silently, and waited for the door. Closed and closed, my mind recalled the story of hearing a 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 to it, Zhang Zizhong took an analogy and immediately came up with an accidental idea. Since British mathematicians can decipher the German cipher, why didn't he find a Chinese mathematician to try to decipher the Japanese cipher system?

"What the general said is exactly. If it wasn't for your idea, I would not 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 classmate Yu." Zhang Zizhong smiled, glanced at the light yellow door of the confinement, and reminded.

For Zhang Zizhong, the red secret deciphering project led by Hua Luogeng is the most concerned and concerned thing recently. In order to ensure the confidentiality of the entire project, Zhang Zizhong travels extremely carefully and secretly, so as not to let interested people and Japanese spies discover their whereabouts and expose them. Project and Professor Hua Luogeng.

If it is said that the secret affairs office of the Blue Shirts Agency arranges top secret agents to steal the secrets of the Japanese army, it is a small matter, then the red secret deciphering project carried out by Professor Hua Luogeng and Yu Hua is digging the roots of the Japanese army.

Once successful, the benefits are almost unimaginable.

……

Facts are always at odds with plans, and plans can never keep up with changes.

Just as Yu Hua thought that the first batch of original plaintext materials would be enough to decipher the true meaning of all the letters of the red secret system, but the final result failed to do so.

It is hoped that the second batch of original plaintexts will have a large enough sample size of the remaining letters.

After entering the study, Hua Luogeng and Yu Hua divided the work. Yu Hua was responsible for the first 2500 copies of the second batch of original plaintexts, and Hua Luogeng was responsible for the last 1000 copies of the second batch of original plaintexts.

Sitting in front of the newly added desk, with a cup of hot tea on his left hand, Yu Hua had a natural face, opened the first original plain text with his right hand, turned his eyes to the surface of the paper, read the content, and extracted all the different combinations above that looked extremely abstract and messy on the surface. English alphabet.

This original plain text from the Kwantung Army Headquarters in Xinjing has a lot of content, about 300 letters, and contains a wealth of scarce remaining letters. The two letters X and Z appear frequently, and the number is 35 and 28 times respectively.

After reading it in a second, his eyes extracted all the letters like an electronic scanner and stored them in his brain. Yu Hua already had an idea in his heart, and vaguely analyzed the true meaning of the remaining letters. He quickly placed the first original plaintext in his left hand, and held it in his right hand. Put the second original plaintext in front of you.

Read, record, organize.

Yu Hua is like a deciphering machine with no emotions, frantically recording the contents of the second batch of original plaintext data, with high efficiency, almost the same as the real machine. Hua Luogeng, sitting in front of another desk, saw Yu Hua's working status, the corner of his mouth. He smiled, and then proceeded to decipher on his own.

In terms of mental arithmetic ability, his apprentice is definitely number one in the country.

The important thing is that Yu Hua, who especially likes mental arithmetic, has not missed a single number so far. He has an extraordinary talent and sensitivity to mathematics.

Research does not know the years, and time passes quietly.

As Yu Hua collected the original plaintext content in his unique research method, there were more and more original English letters that had not been parsed and studied in his mind, and soon exceeded [-] from [-].

fifty thousand.

One hundred thousand.

20 places.

Relying on the cooling and soothing effect of the golden mathematical symbols, Yu Hua's work efficiency was extremely high and stable. After only one and a half hours, all 2500 original plaintext data were recorded and stored in the brain, and the total number reached 47.

Start parsing.

After the collection of the second batch of 2500 original plaintext data, Yu Hua took a deep breath, closed his eyes, and without hesitation, controlled his brain to start working at full power, and entered the most important analysis step in the deciphering process.

The whole 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, specially classified. Yu Hua spent his brain power to maintain more than 47 English letters, while he was distracted by arranging and classifying various letter combinations, and then focused on analysis.

This is three-in-one.

Now, Yu Hua has become a full-fledged human-shaped computer, and his brain is performing terrifying calculations and analytical deductions that are unimaginable to ordinary people at all times.

An hour later.

Yu Hua suddenly opened his eyes, his eyes flickered with light, his black pupils seemed to reveal a mysterious and vast meaning like a black hole, his face was pale, and his brain was resting at full load for more than an hour. It is quickly offset by the golden math symbols in the center of the mind.

"Huh..." Yu Hua let out a sigh of relief and relaxed.

"Xiaohua, is there anything wrong?" At this moment, a gentle voice came over, and Hua Luogeng was standing in front of the desk, looking concerned, and asked.

With golden math symbols to counteract the fainting feeling, Yu Hua, who performed a full-load calculation again, felt much better, shook his head lightly, and gave a good news: "It's okay, Professor, I have deciphered all the last thirteen letters, which are English letters. Matrix numbers."

When the words fell, 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 remaining letter samples contained in the second batch of original plaintext data were so abundant that Yu Hua could decipher all the last thirteen letters in one go.

"Okay, I have deciphered one of the top thirteen characters, the total number of deciphered letters has reached 1, and there are four remaining. Now is the last moment of deciphering. You go out to announce the good news first, and then eat and rest, my side 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 in his right hand, and arranged.

The countdown to deciphering the 26 English letters of the red secret system has arrived.

Once all the English letters are deciphered, the original matrix can be established, and Hua Luogeng can perform the inverse matrix calculation, and finally realize the deciphering of the red secret.

It can be said that this is the most critical and important moment of the whole work, and he cannot help but delay.

"Yes."

Yu Hua nodded in response, took a deep breath, and adjusted his state.

Get up and open the door.

It was late and the lights in the living room were bright. Zhang Zizhong and others sat on the sofa and closed their eyes to rest.

"Student Yu, how is it, is there any news?" At this time, Zhang Zizhong, who was resting with his eyes closed, keenly felt that someone was looking at him, opened his eyes, saw Yu Hua standing at the door, and quickly got up. before, asked.

Tian Hong and Li Ping, who were on the side, noticed the movement, and immediately woke up, and got up and stepped forward.

What is it like to have a sense of having a child...

Seeing the three people reacting like this, Yu Hua suddenly had the feeling that he was a doctor in the delivery room. The three people who were waiting for the red secret to decipher the news were like the panicked and anxious family members of the mother outside the delivery room.

"It has been deciphered to the 22nd place, and there are 4 left. It's the final moment." Yu Hua shook off the strange thoughts in his heart, faced Zhang Zizhong and the three, and gave the current deciphering progress.

It has to be said that the efficiency of the red secret deciphering is terrifyingly fast, and it is completely abnormal. It has reached the level of progress in hours. When the code is deciphered abroad, the progress has not progressed, and it is common to wait for months and half a year.

"There are still four left, that is to say, the results will be available today at the earliest, 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 Peiping team, and Li Ping, his assistant, held their breath and stared at Yu Hua with eyes full of anticipation.

Yu Hua nodded: "Almost..."

The time is correct. Today is Friday and tomorrow is Saturday. He rests for a while today, and plans to stay up late and work overtime to solve the last four letters at one time.

Zhang Zizhong took a deep breath, turned around, and gave an order to Li Ping: "Major Li, tell the driver, I will be staying here tonight. In addition, a soldier from a company will be dispatched and a card will be set up at the west gate of Tsinghua Garden. There are suspicious persons. Get close and kill."

In the end, there was a trace of murderous intent.

"Yes!" Li Ping immediately straightened his back and raised his hands in salute.
