Chapter 124 Work hard for China!
As a cipher system jointly used by the Japanese diplomacy and the Japanese army, thousands of pieces of various important information are encrypted by the red secret every day, and they are exchanged everywhere.

Deciphering the meaning and importance of the red secret, even if you think about it with your toes, you will know how big it is.

At the last moment of deciphering the red secret, Zhang Zizhong, a Chinese soldier, deeply understands the importance of this critical moment and must improve the security force of Tsinghua Garden.

If he didn't want to disturb the potential Japanese spy, Zhang Zizhong would even order the mobilization of a regiment of troops. He can't put too much emphasis on the work of deciphering the red secret.

Yu Hua stood at the door, facing the majesty and killing intent of a high-ranking Chinese general. Zhang Zizhong, who was usually humble and gentle, became an iron-blooded general in an instant, and his body was filled with a majestic and majestic aura like a mountain.

Iron-blooded, decisive, majestic.

This is the unique temperament of the war years.

"General Zhang, I'm going to eat." Major Li Ping left immediately. After waiting for Li Ping to leave, Yu Hua said to Zhang Zizhong with a smile on his face.

"Let's go, classmate Yu, I, Zhang Zizhong, can't help you because of my stupid brain. I'll decipher the red secret. I'll ask you and Professor Hua." Hearing Yu Hua's voice, Zhang Zizhong came back to his senses. With a smile, he became humble again, and his words were full of respect.

"Hua knows that he must work hard for China."

Yu Hua smiled and then walked to the kitchen.

In the kitchen, there was a meal prepared by my wife, Wu Xiaoyuan. It was simple and hot. The big white steamed bun was filled with pickles and vegetable soup, which quickly solved the belly problem.

After eating and drinking, Yu Hua went straight to the second bedroom under the watchful eyes of Zhang Zizhong and others, undressed and went to bed, ready to rest.

The better the rest, the faster the energy recovery.

Lying on the bed, setting the alarm clock, the exhausted Yu Hua fell into a deep sleep and entered a deep sleep state. His brain was clean and he did not dream. At this time, the golden mathematical symbols in the center of the mind played a subtle role all the time, speeding up the recovery of the brain.

Outside the door, Zhang Zizhong and the others found that Yu Hua quickly fell asleep, and his movements and voices became more subtle. All three present understood that the last moment of deciphering the red secret was inseparable from the leader Hua Luogeng, and even more inseparable from calculation. Yu Hua, who is extremely capable.

All they can do is... be on call at all times.

……

The night was getting dark, and the cold wind was howling outside the window.

Time passed by minute by minute.

"Ding!" After an unknown amount of time, the alarm clock placed on the bedside table in the second bedroom suddenly made a clear and urgent sound.

Yu Hua, who was at the end of the sleep cycle, immediately opened his eyes when he heard the sound of the alarm clock, and pressed the alarm clock with his right hand. There was a sense of refreshment in his brain, without the previous feeling of exhaustion and syncope.

I checked the time, it was already 12:30 in the evening.

"Phew... The state has recovered to about 80%, which is enough to support the final breakthrough." Feeling the state of his brain, Yu Hua took a deep breath, his eyes flashed with light, he simply adjusted his state, and immediately got dressed and got up.

When he came to the door, the door opened, and the living room was filled with smoke. Zhang Zizhong was sitting by the sofa, smoking a cigarette.

Tian Hong and Li Ping sat upright and meticulous.

"General Zhang, I'm in." Yu Hua said to Zhang Zizhong, and when Zhang Zizhong nodded, he came to the door of the study.

Pushing the door and entering, the study was also filled with smoke, Hua Luogeng was sitting in the desk with a slightly thin figure, with a cigarette in his left hand, his eyes were bloodshot, his body showed extreme fatigue, and the whole person was still focused on looking at the table top. Pieces of original plaintext data, holding a Parker pen in the right hand, constantly analyzing and deducing on the scratch paper.

On the table there is a cup of cold tea and a meal that has already been eaten.

"Professor, how is the situation?" Yu Hua made a cup of hot tea, came to the table, gently put it down, and asked.

"Three left, EGM."

Hua Luogeng heard a familiar voice in his ear, raised his head to respond, and rubbed his extremely sour eyes. After seeing the hot tea on the table, he was moved and smiled.

It is a step closer to deciphering the 26 letters of the red secret.

"Leave the next work to me. You rest first and save your energy for the final inverse matrix deduction. I will build the original matrix." Yu Hua heard that and said to Hua Luogeng.

"Okay, with you here, tonight our master and apprentice will stay up all night, and we will also get the original matrix out." Hua Luogeng was not pretentious, maintained his face as a master, stood up, left the position to Yu Hua, and pumped hard. With a cigarette, his deep and vast eyes shone with light, and he said solemnly.

The momentum is like a tiger, strike while the iron is hot, and we must come up with the original matrix tonight.

"Hua understands." Yu Hua smiled, went straight to the desk and sat down, took the last baton from Hua Luogeng, and quickly took over the rest of the work.

He picked up the 2818th original plaintext in his right hand, put it in front of him, scanned the records with his eyes, and stored them in his mind. The whole process was fast and fast. At this moment, Yu Hua once again turned into an emotionless pedestrian computer.

"I hope that the moment I wake up, I can see the original matrix." Hua Luogeng looked at Yu Hua who was in the working state, full of anticipation, he retreated to the seat behind, did not disturb Yu Hua, leaned against the cold chair, extremely tired He quickly fell asleep.

Yu Hua used his exclusive method to decipher the password, sorting in one second, scanning in one second, and storing in one second. All stored in the brain.

After the content collection was completed, Yu Hua did not hesitate to enter the most energy-consuming state of parsing and deciphering, maintaining hundreds of thousands of unparsed English letters at the same time, peeling them away, and gradually finding the regularity of specific letters and letter combinations.

The energy, which was enough to maintain a state of efficient study for several hours just recovered, has been reduced in a geometric form. When it comes to deciphering the last three letters, the difficulty of deciphering has not decreased, and it is even higher than the original.

Password cracking is not like a simple problem. The first step is to parse undeciphered letters, the second step is to extract specific letters and letter combinations, and the third step is to analyze according to specific letters and letter combinations.

The third step is the most critical. It must be extremely accurate to parse out the real numbers of the last three letters. If there is an error, it will be disastrous.

The letters that are not yet fully deciphered are EGM and the numbers are 25, 18, 9.

Assuming that the letters of the red dense real matrix are E=25, G=18, M=9, then Yu Hua cannot parse the E letter as 9. If it is parsed as 9, then the original matrix cannot be established.

Fifteen minutes later, Yu Hua, who was sitting in front of the desk with his eyes tightly closed, opened them suddenly with a gleam of light in them, and immediately picked up the Parker pen with his right hand.

E=18,

M=25,

G=9.
