Chapter 117 Lugou Bridge!
"This..." Hearing the plan given by Yu Hua, Zhang Zizhong was in trouble, and his eyes subconsciously turned to Tian Hong who was on the side. This matter can only be decided by Tian Hong, who is the head of the Peiping Secret Service of the Blue Clothes Society. Decide,
Tian Hongyu frowned, glanced at Yu Hua, and said solemnly: "I'm afraid it won't work. It's not that I don't trust you, classmate Yu Hua, but that this original Japanese plaintext material is of great importance. Both you and Professor Hua will be in danger."

This is what Tian Hong is worried about. It is not that he does not trust Yu Hua. After all, for Tian Hong, a group of military intelligence agencies from the Blue Shirt Club, Yu Hua, who has the status of a 'survivor of fallen soldiers', can be regarded as a genuine Miaohong and count as himself. people.

The undercover investigation and other audits on Yu Hua have been approved.

However, the problem is security.

Copy a copy of the original plaintext data and bring it to Peking No. [-] Middle School for research. Once it is leaked, the consequences will be disastrous.

No one knows how many Japanese agents are in Peiping City, including him who is in charge of Peiping City.

"Team Leader Tian is right. The risk is too high to copy a copy of the document and carry it out. I don't think you want Professor Hua to fall into a dangerous environment." Zhang Zizhong nodded in agreement, his eyes turned to Yu Hua, and said.

Hua Luogeng, who was beside him, didn't speak, with a smile on his face, he waited quietly.

"Team Leader Tian, ​​General Zhang, what I mean by copying is that I use my brain to write down all the materials and bring them back to school, not to copy written materials. Using my brain can eliminate all risks of leakage. I'm sorry, what I said just now may have misled you." Yu Hua shook his head, re-explained the meaning of 'copy', and apologized softly.

"..."

The room fell silent for a moment.

Zhang Zizhong: "..."

Tian Hong: "..."

Sorry to bother you, and forgive our inability to understand the mind and world of geniuses.

"Student Yu Hua, can you write down all the information?!" At this time, Li Ping, an assistant from the Whampoa Military Academy, made a sound for the first time, his face was serious, and his words revealed a hint of incredulity.

No doubt, just… unbelievable.

Write down all the original plaintext data?
How can this be? !
The entire original plaintext data was written by Li Ping, who was in charge of sorting and summarizing. The sources covered Fengtai, Shanhaiguan, Guanwai, Dongjiaominxiang, etc. Japanese troops and diplomatic departments, and finally handed over to Hua Luogeng. The content is huge, as high as more than 2000 copies , the number of English letters in each plaintext document varies, between forty and two hundred.

What is this concept?
In other words, Yu Hua, a teenage high school student, actually wanted to memorize a total of 20 to [-] letters.

Mr. Zhongshan is above, how is this possible?

"should be no problem."

Yu Hua said modestly, and then gave the contents of two original plaintext materials in one breath: "The alphabetical order of the 354th original plaintext is: aabbahhfzkzk... The 295th original plaintext alphabetic order is... Of course, if you don't believe it, you can randomly Extract any original plaintext material before the 700th material."

Li Ping was speechless: "..."

Should this be okay?

He suddenly felt that he, a top student from the 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 was him, don't say anything about the hundreds of documents. I'm sorry, that's too much of a respect for him. He couldn't even remember the tenth original plaintext document.

The original plaintext with no regularity is far more difficult to remember than the dogmatic and abstract knowledge taught in military academies.

With Yu Hua's 'demonstration', Li Ping's doubts about Yu Hua disappeared instantly, as did Zhang Zizhong and Tian Hong.

"In this case, I don't think it's a 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: "Yes, but, classmate Yu Hua, Tian still has to remind him to pay attention to safety."

"Yu Hua knows, thank you for your concern." Yu Hua was slightly surprised, thinking that Tian Hong would remind him not to leak the secret, but he was concerned about safety and nodded in response.

"Okay, the matter is decided, Xiaohua, how are you now? If there is no problem, let's try to decipher some of the original plaintext words first." Hua Luogeng looked serious and looked at Yu Hua.

"no problem."

Yu Hua carefully felt the golden mathematical symbol suspended in the center of his mind. After obtaining this mathematical symbol, the brain's energy recovery speed was much faster, and it was able to support the deciphering of some original plaintext words.

When the words fell, he rolled over and got off the bed, quickly putting on his shoes.

He was interested in trying to decipher some of the original plaintext words.

"Let's go to the study, General Zhang, you are still waiting outside, don't disturb us, if there is no problem, the result will be available in about an hour." After Yu Hua put on his shoes and was ready, Hua Luogeng nodded and asked Zhang Zizhong Wait for someone to ask, and leave 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's okay, Yu Hua smiled politely to Li Ping, who was still a little lost, and left the second bedroom.

The two masters and apprentices quickly came to the study.

In the study, it was already twilight outside the window.

"Xiaohua, this is the approximate matrix mathematical model I established. 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 from the drawer An approximate matrix mathematical model that has been calculated and handed to Yu Hua.

"Amazing..." Yu Hua stared at the scratch paper in his hand, full of admiration. He didn't expect that Hua Luogeng had already built the approximate matrix mathematical model proposed earlier. The entire model belongs to a special type of matrix, and the eigenvalues ​​and eigenvectors have been marked. , next to 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 a basic understanding and completed the corresponding modeling in his brain.

"We assume that the other sixteen letters are... first multiplication calculation, and then transpose calculation, pay attention here, must be opened as determinant..."

In the study, the voice of Hua Luogeng's explanation was permeated.

Yu Hua, who completed mathematical modeling in his brain, followed Hua Luogeng's ideas step by step, and carried out calculation deductions. His computer-like brain continued to carry out various complex calculations and a large number of repetitive calculations, and wrote the calculation results.

One calculation result after another was continuously given. Hua Luogeng, who can be called the No. 1 Chinese mathematics level, continued to make 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 opened his eyes.

Yu Hua turned his eyes to the Japanese Hiroshima dialect words on the desktop, his face was serious, he held a pen in his right hand, and wrote two Japanese words on the scratch paper: "According to the final calculation result of the approximate matrix mathematical model, compare the Japanese Hiroshima dialect words, the first original The plaintext parses out two words - Lugou Bridge... exercise."

Lugou Bridge!
exercise!

When Hua Luogeng heard this, his heart was shocked and his face was serious: "Are you sure?"

There are too many things in these two words. Even Hua Luogeng, who is not a spy, can parse a lot of things from these two words.

"Sure!" Yu Hua affirmed.

PS: The body is gradually getting better, and more and more in the past two days.
