"This..." After hearing the plan given by Yu Hua, Zhang Zizhong was troubled, and his eyes subconsciously turned to Tian Hong. This matter could only be decided by Tian Hong, who was the head of the Blue Clothes Society's Secret Service in Peiping. He
Unable to decide,
Tian Hong frowned, glanced at Yu Hua, and said seriously: "I'm afraid this matter can't be done. It's not that I don't trust you, classmate Yu Hua, but this Japanese original plain text information is very important. If it is leaked and known by Japanese spies,
Both your life and Professor Hua's life will be in danger."
This is what Tian Hong is worried about. It's not that he doesn't trust Yu Hua. After all, for Tian Hong and other military intelligence agencies who came from the Blue Clothes Society, Yu Hua, who has the status of a 'resident of a fallen soldier', can be regarded as a genuine Miao Hong.
people.
The secret investigation and other reviews regarding Yu Hua have been passed.
But, the problem is safety.
Copy a copy of the original clear text information and take it to Peking No. 4 Middle School for research. Once it is leaked, the consequences will be disastrous.
No one knows how many Japanese spies there are in Beiping City, including him, who is the person in charge of Beiping City.
"Team Leader Tian is right. The risk of copying a copy of the information and taking it out is too high. I think you don't want Professor Hua to fall into a dangerous environment." Zhang Zizhong nodded in agreement and turned to Yu Hua with his eyes.
Hua Luogeng on the side did not speak, but waited quietly with a smile on his face.
"Team Leader Tian, General Zhang, what I mean by copying is that I use my brain to record all the information and bring it back to school, rather than copying written materials. Using my brain can eliminate all risks of leakage. I'm sorry, what I just said may have misled you."
Yu Hua shook his head, re-explained the meaning of 'copy', and apologized softly.
"..."
The room fell into silence for a moment.
Zhang Zizhong: "..."
Tian Hong: "..."
Sorry to bother you, and forgive us for not being able to understand the thinking and world of geniuses.
"Classmate Yu Hua, can you write down all the information?!" At this time, Li Ping, an assistant from the Huangpu Military Academy, spoke for the first time, with a serious face and a hint of incredulity in his words.
No doubt, just... unbelievable.
Write down all original plaintext information?
How is this possible?!
The entire original plain text material came from Li Ping, who was responsible for sorting and summarizing it. The sources covered Fengtai, Shanhaiguan, Guanwai, Dongjiaominxiang and other Japanese military and diplomatic departments. It was finally handed over to Hua Luogeng. Its content is huge, up to more than 2,000 people.
The number of English letters in each piece of plain text information varies, ranging from forty to two hundred.
What is this concept?
In other words, Yu Hua, a teenage high school student, actually had to memorize a total of 80,000 to 200,000 letters.
Mr. Zhongshan, how is this possible?
"It should be fine."
Yu Hua said modestly, and then gave the contents of two original plaintext data in one breath: "The alphabet order of the 354th original plaintext is: aabbahhfzkzk... The alphabetical order of the 295th original plaintext is... Of course, if you don't believe it, you can randomly
Extract any original plaintext data before the 700th piece of data."
Li Ping was speechless: "..."
Shouldn't this be a problem?
He suddenly felt that he, a top student from Whampoa Military Academy, was nothing in front of this high school student, and an extremely strong and heavy sense of IQ suppression enveloped his heart.
If it were him, let alone the hundreds of pieces of information, I'm sorry, that would really look down on him, and he wouldn't be able to remember even the tenth piece of original plaintext information.
The original plain text with no rules is much more difficult to memorize than the dogma and abstract knowledge taught in military schools.
Following Yu Hua's 'demonstration', Li Ping's doubts about Yu Hua disappeared instantly, as did Zhang Zizhong and Tian Hong.
"In that case, I see no problem, Team Leader Tian, what do you think?" Hua Luogeng said to Tian Hong with a smile on his face.
Tian Hong pondered for a while and finally nodded: "Okay, but classmate Yu Hua, Tian still needs to remind you to pay attention to safety."
"Yu Hua knows, thank you for your concern." Yu Hua was slightly surprised. He thought Tian Hong would remind him not to leak the secret. Unexpectedly, he was concerned about safety and nodded in response.
"Okay, the matter has been decided. Xiaohua, how is your health now? If there is no problem, we will try to decipher some of the original plaintext words first." Hua Luogeng looked at Yu Hua with a serious face.
"no problem."
Yu Hua carefully felt the golden mathematical symbol suspended in the center of his mind. After acquiring this mathematical symbol, his brain energy recovered much faster and was able to support deciphering some of the original plaintext words.
After saying this, he turned over and got out of bed and quickly put on his shoes.
He became interested in trying to decipher some of the original plaintext words.
"Let's go to the study, General Zhang. You should wait outside and don't disturb us. If there is no problem, the results will be available in about an hour." After Yu Hua put on his shoes and was ready, Hua Luogeng nodded and asked Zhang Zizhong
After giving instructions, he left first.
"Professor Hua, classmate Yu, please." Zhang Zizhong and Tian Hong said in unison to Hua Luogeng and Yu Hua with serious faces.
Hua Luogeng waved his hand, indicating that it was okay. Yu Hua smiled politely at Li Ping, who was still a little lost, and left the second bedroom.
The master and apprentice quickly came to the study.
In the study, it was already dusk outside the window.
"Xiaohua, this is the approximate matrix mathematical model I built. Through this model, we can decipher some words. These are the ten letters we have now..." Hua Luogeng came to the desk and immediately took it out of the drawer.
An approximate matrix mathematical model that had been calculated was handed to Yu Hua.
"Awesome..." Yu Hua stared at the draft paper in his hand, filled with admiration. Unexpectedly, Hua Luogeng had already built the approximate matrix mathematical model proposed before. The entire model was a special type of matrix, and the eigenvalues and eigenvectors had been marked.
, next to it is the derived determinant, the content structure is concise and rigorous, and the beauty of mathematics is reflected everywhere.
After reading the entire model, Yu Hua has basically understood it and completed the corresponding modeling in his brain.
"We assume that the other sixteen letters are... first calculated by multiplication, and then calculated by transposition. Note here that they must be opened as determinants..."
The study room was filled with the sound of Hua Luogeng's explanation.
Yu Hua, who completed the mathematical modeling in his brain, followed Hua Luogeng's ideas step by step to perform calculations and deductions. His computer-like brain continued to perform various complex calculations and a large number of repetitive calculations, and wrote out the calculation results.
One calculation result after another was given continuously. Hua Luogeng, who is regarded as the first person in Chinese mathematics, continued to perform in-depth calculations based on the calculation results given by Yu Hua.
The cooperation between the two is perfect.
"What was the result?" An hour later, Hua Luogeng was sweating and looked at Yu Hua, who had already opened his eyes.
Yu Hua looked at the Japanese Hiroshima dialect words on the table, with a serious face. He held the pen in his right hand and wrote two Japanese words on the scratch paper: "Based on the final calculation results of the approximate matrix mathematical model, comparing the Japanese Hiroshima dialect words, the first original The plain text parses out two words - Marco Polo Bridge...exercise."
Marco Polo Bridge!
exercise!
When Hua Luogeng heard this, he was shocked and looked serious: "Are you sure?"
There are so many things contained in these two words. Even Hua Luogeng, who is not a spy, can analyze a lot of things from these two words.
"Sure!" Yu Hua affirmed.
