"Luo Geng, let's leave the manuscript here for now. I'll go through the submission process with Brother Di Zhi and Brother Heshou later. If there's no problem, I'll be able to catch up with the April issue of the journal." After sighing in his heart, Yang
Wu Zhi collected his emotions and turned his attention back to the matter of submission. He looked at Hua Luogeng who was smiling at the side, pondered for a while, and made arrangements.
"Okay, teacher, I'll go back first. I still have things to do." Hua Luogeng nodded. With Yang Wuzhi's words, things were basically settled. After talking about the matter, he said goodbye and prepared to leave.
"Luo Geng, the teacher sincerely advises you not to have anything to do with the Blue Clothes Secret Service. Academics do not participate in politics. You are a genius and you will have great potential in the field of mathematics in the future." Yang Wuzhi looked at the man whose strength and performance had surpassed his own.
Hua Luogeng took a deep breath, and as a teacher, he softly advised.
There was a hint of solemnity in his words.
Hua Luogeng, who had a middle school degree, was the most talented mathematical genius he had seen in so many years. Yang Wuzhi saw in Hua Luogeng the potential to dominate the Chinese mathematics community in the future.
Yang Wuzhi never wanted to see Hua Luogeng get involved too much in politics, causing a mess, wasting his talents, and ruining his life.
"Luo Geng knows."
Hua Luogeng fell into silence after hearing these words. After two seconds, a solemn look appeared on his face: "I don't participate in politics, but I want my head to play a role for the country and the nation, and this,
This is why I chose to assist the Blue Shirt Club."
Yang Wuzhi was silent.
After a while, the whole person sighed, with a rather complicated look in his eyes: "Go ahead, I hope you get your wish."
He still didn't choose to agree.
"Goodbye, teacher." Hua Luogeng was not surprised by the attitude of his mentor Yang Wuzhi. He bowed slightly, raised his hands to bow, performed a teacher's salute, and turned to leave.
"By the way, will your apprentice be involved in this matter?" Yang Wuzhi suddenly thought of something, looked at Hua Luogeng's back and said.
Hua Luogeng, who had already reached the door, turned around and said, "Yes."
"Okay." Yang Wuzhi's eyes became more complicated.
"Bang!" Soon, with the sound of a door closing, the office became quiet again.
"Blue Clothes Club..."
After a while, a long sigh came from the office.
Outside the window, the sun is shining brightly.
…
Learning does not count the years.
Under the double gentle caress of the two disciplines of real variable function theory and cryptography, Yu Hua spent the last weekend of March, enjoying the massage of cryptography on Saturday morning and feeling the care of real variable function theory in the afternoon. Yu Hua was deeply affected by it.
Be happy and reluctant to miss Shu, be addicted to the ocean of knowledge and be unable to extricate yourself, and enjoy this kind of pleasure that can only be felt by a few people in human civilization.
Master the knowledge and master everything.
With continuous learning, the overall mathematical strength of the whole person improved at a speed visible to the naked eye. Soon, the theory of real variable functions reached the beginner level, further improving the basic structure of the thinking finite element analysis system. At the same time, Yu Hua's cryptography was about to
Meet Hua Luogeng’s minimum requirements.
"Okay, that's all the knowledge about matrices and determinants. I've finished talking. Yu Hua, how do you know about determinants?" In the study, Hua Luogeng stood next to the blackboard filled with mathematical formulas and characters, put down the chalk, and asked
Yu Hua, who was directly in front, said.
"Understanding everything." Yu Hua put down his pencil with a natural look on his face and replied towards Hua Luogeng.
Determinant is a key property of matrices. In later generations, it is one of the traps that makes people fall into the pit of mathematics. However, what is interesting is that in this era, the study of matrices and determinants were still two separate knowledge points, and they have not been put aside for the time being.
Come together.
"Then let's see how to solve this problem." Hua Luogeng turned around and erased the determinant expression formula and related theorems on the blackboard, and quickly wrote a linear algebra problem of matrix determinant with chalk. After writing, he used Yu Hua to do
question.
Yu Hua stared at the question. After a second, the entire solution process appeared in his mind. With a calm expression, he stepped forward to the blackboard and picked up the chalk to answer the question.
"Da da da!" The sound of chalk falling on the blackboard continued to be heard, and then, exclusive mathematical symbols appeared one by one.
Hua Luogeng, standing aside, looked at the problem-solving process on the blackboard, looked at the proof content and formulas given by Yu Hua, and couldn't help but nodded, with a look of affirmation in his eyes.
After thirty seconds, the entire problem is solved.
"Professor, I'm done." Yu Hua gently put down the chalk and said respectfully to Hua Luogeng with a solemn face.
It is now class time, and even though Yu Hua is not yet an official National Tsinghua University student, he must have the proper discipline and etiquette.
"Yes, the answer is correct."
Hua Luogeng did not turn his head to look at the blackboard. As early as halfway through Yu Hua's proof process, he already knew that Yu Hua would write the correct answer. He smiled and praised.
After receiving the praise from Hua Luogeng, Yu Hua was happy and happy, smiling without saying a word and without any expression of pride.
He is only happy to master knowledge, not proud of mastering knowledge.
"That's it for today's cryptography class. Yu Hua, come here." Seeing Yu Hua's reaction, Hua Luogeng laughed and shook his head. As his apprentice, he had a calm attitude and ended today's class. He put down his teaching tools and faced Yu Hua.
He shouted, turned around and walked towards the desk.
"yes."
Yu Hua nodded and followed him to the table.
I saw Hua Luogeng sitting on a chair with a serious expression. He took out a metal key from his body, opened the compact desk drawer, and then took out a black document bag. The top of the document bag had a pattern of blue sky and white sun, and the surface was printed with Agent of the Blue Clothes Club.
The word "Secret" is written next to it. It is not difficult to guess that this document bag contains all original Japanese documents.
"Yu Hua, after learning determinants, it means that you have mastered matrix theory, and your cryptography level has met the requirements for deciphering Japanese ciphertexts. However, before you formally come into contact with the work of deciphering Japanese ciphertexts, the master will ask you one last time whether you are willing to participate.
In this job, we must abide by secrets and never betray the motherland." Hua Luogeng placed the entire black document bag on the table, his face was more solemn than ever before, he sat upright with a serious expression, and his piercing eyes were as sharp as sharp knives.
Staring at Yu Hua closely, he said in a deep voice.
Keep secrets strictly and never betray the motherland.
This is the core requirement for those who are engaged in deciphering Japanese ciphertext.
"Yu Hua is willing to participate in this work, abide by the secrets, and will never betray the motherland." Yu Hua said eloquently with a sacred and solemn face, a trace of determination in his clear and energetic eyes.
"No matter who will be the master of the country in the future, we are all Chinese. Remember, if you betray the motherland in any way, you and I will no longer be masters and disciples. Do you know that?" Hua Luogeng nodded and said seriously.
The solemn look on Yu Hua's face did not diminish at all, and he knew that Hua Luogeng's words were no lie: "Students will remember it."
