Chapter 452 Purple Secret!

The next morning, the rising sun shone into the dormitory through the shade of the trees.

Yu Hua, who had slept all afternoon and night, opened his eyes, feeling refreshed and in excellent condition. He glanced at his watch and saw that it was already 8 a.m.

After stretching comfortably, Yu Hua got up, dressed, went to the toilet to wash up, tidied himself up briefly, took out his lunchbox, and prepared to go to the cafeteria for lunch.

"Knock knock." Two knocks came from the door of room number 29. The sound was not loud, and the person knocked lightly on the door.

"Hold on."

Hearing the noise, Yu Hua responded, put down his lunchbox, and went to the door to open it. Then, an extremely familiar face came into view. Upon seeing the person, Yu Hua was immediately stunned.

The visitor was not the local military intelligence officer, but his own master, Hua Luogeng.

"Master." Yu Hua quickly bowed and greeted him, his words full of respect.

Hua Luogeng stood in front of the door, a gentle smile on his face. Looking at Yu Hua's familiar yet slightly mature face, he felt gratified and nodded, saying, "Not bad, you didn't get lost. You only came to the school to register in October. Your master thought something had happened to you."

Hua Luogeng was very concerned about the safety of his disciple, especially after he learned that he and Yu Hua had been listed as key targets by the Japanese army.

"I should have arrived much earlier, but I was delayed by various things." Yu Hua showed a helpless expression.

"It's alright, as long as everyone arrives safely. I've come to tell you something. Come inside, this isn't the place to talk." Hua Luogeng smiled and gestured for Yu Hua to come inside.

Yu Hua nodded and made way for Hua Luogeng, then closed and locked the door after Hua entered the room.

"Master, what is it?" Yu Hua turned around and asked.

"Since we published our paper on asymmetric cryptography, the cryptographic systems of armies around the world have been updated to asymmetric cryptography, including the National Revolutionary Army and the Japanese Army. After the outbreak of the War of Resistance against Japan, the Japanese Army organized a large number of domestic mathematics experts and spent a lot of manpower and resources to decipher the National Revolutionary Army's cryptographic system. However, the final result was as we had predicted: the Japanese Army could not break through the defense layer of the first-generation asymmetric cryptography."

Hua Luogeng's expression turned slightly serious as he slowly said, "In order to achieve their decryption goals, the Japanese military's intelligence system has turned its attention to you and me."

"In other words, we are now a key target of the Japanese military's intelligence system. We will either be used by the Japanese or be assassinated." Yu Hua replied solemnly after a moment of silence.

"Yes, this information was given to me by the Military Intelligence Bureau. They have already sacrificed eight people to protect the safety of me and your teacher's wife. The Military Intelligence Bureau is the former Blue Shirts Society."

Hua Luogeng nodded, his voice full of emotion, and then truthfully stated the purpose of his visit: "I'm here to see you again, just like last time, to ask if you'd be willing to participate in the work of deciphering Japanese military codes. I'm in charge of this matter. If we can successfully decipher the Japanese red codes like last time, it will be of great help to the War of Resistance. Of course, it's okay if you're not willing; the Military Intelligence Bureau will still send people to protect you."

Deciphering Japanese military codes may not seem particularly dangerous on the surface, but if the information is leaked, the participants will immediately become thorns in the side of the Japanese military's intelligence system, and will be targets to be eliminated as soon as possible.

“The students are willing.”

Upon hearing this, Yu Hua nodded in agreement without hesitation.

Participating in the codebreaking work was Yu Hua's original plan.

With no other options, Professor Zhuang Qianding stayed at the base, Professor Zhao Zhongyao was still secretly protecting the most important 50 milligrams of radium, and both general education elective course professors were absent. They couldn't possibly stay in bed playing around until the Boxer Indemnity Scholarship students' exam was held, so Yu Hua could only follow his master's lead in making trouble.

Despite the extreme difficulty of deciphering asymmetric cryptography, Yu Hua remained highly interested. As the founder of asymmetric cryptography, he did not believe that the encryption algorithms and cipher tables developed by the Japanese army could reach the level of the first-generation asymmetric cryptography system.

"Okay, go to the cafeteria for lunch first, and come find me on the third floor of the library later." After receiving Yu Hua's reply, Hua Luogeng smiled and nodded, giving him further instructions.

After saying that, he turned around and left.

After several months apart, the master and disciple were reunited, and Hua Luogeng seemed very happy.

“I didn’t expect the Military Intelligence Bureau to send my master as an intermediary, but it makes sense. After arriving in Changsha, my master should have been working on codebreaking at Yuelu Academy. No wonder no news has come out.” Watching Hua Luogeng’s departing figure, one side of him and the other side of him, Yu Hua thought to himself, “Never mind all that, let’s get on with the codebreaking first, then do something else.”

Without much thought, he picked up his lunchbox and headed out to the cafeteria.

……

The third floor of the Yuelu Academy Library.

"Mr. Yu."

After Yu Hua finished breakfast and arrived on the third floor, a young man standing at the top of the stairs greeted him with a respectful and solemn expression, bowing slightly and saying, "I am Fu Guangwen, the stationmaster of Changsha Station."

When dealing with code-breaking experts, Fu Guangwen adopted an extremely humble attitude, showing no airs of authority whatsoever.

Fu Guangwen had no idea that Yu Hua, who was only eighteen years old, possessed such extraordinary mathematical talent and historical achievements. He had cracked the Red Code and written the first generation of asymmetric cryptography algorithms and cipher tables, building a Great Wall for the communication security of the National Revolutionary Army. All of these achievements bore the mark of Yu Hua.

With Yu Hua's help, the ongoing new round of codebreaking work against the Japanese military will be much more efficient.

Despite being the highest-ranking official at Changsha Station, his status and importance are far less than those of Yu Hua, who stands before him.

Boss Dai had given a death order: even if he himself died, he was to do everything in his power to ensure the safety of Professor Hua Luogeng and Yu Hua.

"Hello, Station Master Fu."

Yu Hua smiled and extended his right hand to Fu Guangwen: "Just call me Yu, please don't accept the title of 'sir'. Let's not delay, please let Station Chief Fu take me inside."

"This way, Yu Hua. Professor Luo is in the innermost room." Fu Guangwen extended his right hand to shake hands with him, then naturally released it, and gestured for Yu Hua to go inside.

Yu Hua nodded, bid farewell to Fu Guangwen, and walked along the corridor. Along the way, there were intelligence personnel belonging to the Military Intelligence Bureau on duty in each room, performing security work. He did not pay attention to them and went straight to the innermost room.

Gently pushing open the door, one sees Master Hua Luogeng, with two young men sitting beside him, who appear to be assisting him and not doing any decoding work.

“You’re here, Xiao Hua. This seat across from me is yours.” Hua Luogeng noticed the door open, looked up and saw Yu Hua, smiled, and pointed to the workstation opposite him: “As you can see, it’s still the two of us, master and apprentice, working on the decryption this time.”

Upon seeing Yu Hua arrive, the two young men immediately stood up and straightened their backs.

"Master, are there still no other scholars willing to join the decoding work?" Yu Hua frowned slightly upon hearing this, walked forward to his workstation, and asked.

"As usual, some people look down on codebreaking, some are unwilling to sacrifice academic research, some are unwilling to use their knowledge for war, some feel that this is not good, Professor Xiong and Professor Yang are busy with teaching and don't have time to mess around, and the others are not good enough."

Hua Luogeng shook his head, picked up the Hademen on the table, took out a cigarette, lit it, and took a puff to refresh himself: "Let's not talk about these things. It's not about the quantity of codebreakers, but the quality. You and I are enough. The Japanese spy system has named its own asymmetric code 'Purple Code.' This is my result of deciphering Purple Code over the past two months. Take a look. The general direction should be fine."
