Chapter 113 Mastering knowledge, mastering everything!
"Luogeng, in this way, the manuscript will be placed with me first. Later, I will go through the submission process with Brother Di and He Shou. If there is no problem, I will be able to catch up with the journal in April." After sighing in his heart, Yang Wuzhi Packing up his emotions, he turned his attention back to the matter of submission. Looking at Hua Luogeng who was smiling, he pondered and arranged.

"Okay, teacher, then I'll go back first, I still have things to do." Hua Luogeng nodded. With Yang Wuzhi's words, it was basically stable. After talking about the matter, he said goodbye and prepared to leave.

"Luogeng, the teacher sincerely advises you not to have anything to do with the Secret Service Office of the Blue Clothes Society. The academic world does not participate in politics. You are a genius, and you will have great potential in the field of mathematics in the future." Hua Luogeng took a deep breath, and as a teacher, softly advised.

There was a hint of solemnity in the words.

Hua Luogeng, who has a middle school education, is the most talented mathematical genius he has seen over the years. Yang Wuzhi saw in Hua Luogeng the potential to lead the Chinese mathematics community in the future.

Yang Wuzhi never wanted to see Hua Luogeng get involved in politics too much, causing him to become a showman, wasting his talents, and ruining his life.

"Luogeng understands."

After hearing these words, Hua Luogeng fell into silence, and after two seconds, a solemn expression appeared on his face: "I don't participate in politics, but I want my head to be able to play a role for the country and the nation, and this, It is exactly what I chose to assist the Blue Shirts Club."

Yang Wuzhi was silent.

After a while, the whole person sighed, his eyes were quite complicated: "Go, I hope you do."

He still did not choose to agree.

"Goodbye, teacher." Hua Luogeng was not surprised by the attitude of his teacher Yang Wuzhi, he bowed slightly, raised his hands to bow, gave a teacher 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 were more complicated.

"Bang!" Soon, with the sound of the door closing, the office fell silent again.

"Blue Clothes Club..."

After a while, a long sigh came from the office.

Outside the window, the sun shines brightly.

……

Learning does not know the years.

Under the double gentle touch of the two disciplines of real variable function theory and cryptography, Yu Hua spent the last weekend of March, enjoying a massage in cryptography on Saturday morning, and feeling the care of real variable function theory in the afternoon. Yu Hua was deeply impressed by it. Reluctant to think about Sichuan, indulging in the ocean of knowledge and unable to extricate themselves, enjoying this kind of pleasure that only a few people in human civilization can feel.

Master the knowledge, master everything.

With the continuous learning, the comprehensive mathematical strength of the whole person has improved at a speed visible to the naked eye. Soon, the real variable function theory has reached the beginner level, and the basic structure of the thinking finite element analysis system has been further improved. At the same time, Yu Hua's cryptography will soon be Meet Hua Luogeng's minimum requirements.

"Okay, that's all for the knowledge about matrices and determinants. Yu Hua, how do you know about determinants?" In the study, Hua Luogeng stood beside the blackboard full of mathematical formulas and characters, put down the chalk, and asked Yu Hua, who was in front of him, said.

"Master it all." Yu Hua had a natural face, put down the pencil, and replied to Hua Luogeng.

The determinant is a key property of the matrix, and it is one of the traps that make people fall into the deep pit of mathematics. However, it is interesting that the research on matrix and determinant in this era still belongs to two separate knowledge points. come together.

"Then let's see how to do this problem." Hua Luogeng turned around and wiped off the determinant expression formula and related theorems on the blackboard, and quickly wrote a linear algebra problem with a matrix determinant with chalk. After writing, use Yu Hua to do it. question.

Yu Hua stared at the question, and after a second, the entire answering 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 come out, and then, one by one exclusive mathematical symbols appeared.

Hua Luogeng, who was standing on the side, looked at the problem solving process on the blackboard, and at the proof content and formula given by Yu Hua.

After 30 seconds, the whole problem is solved.

"Professor, I'm done." Yu Hua gently put down the chalk, with a solemn face, respecting Hua Luogeng.

Now it is class time. Even if Yu Hua is not an official National Tsinghua University student, he must have the proper discipline and etiquette.

"Yes, the answer is correct."

Hua Luogeng didn't 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, and praised with a smile on his face.

After receiving the compliment from Hua Luogeng, Yu Hua was happy and happy, with a smile on his face, no words, no proud expression.

He is only happy to have knowledge, not proud of it.

"Today's cryptography class is here, Yu Hua, come here." Hua Luogeng laughed and shook his head when he saw Yu Hua's reaction. His apprentice, with a calm attitude, ended today's class aloud, put down the teaching aids, and moved towards Yu Hua With a shout, he turned and walked to the desk.

"Yes."

Yu Hua nodded and followed, and came to the table.

I saw Hua Luogeng sitting on a chair with a very serious expression. He took out a metal key from his body, opened the tight desk drawer, and then took out a black file bag. It is not difficult to guess that this document bag contains all original Japanese plaintext materials.

"Yu Hua, after learning the determinant, it means that you have mastered matrix theory, and your cryptography academic level has reached the requirements for deciphering Japanese ciphertext. However, before you officially engage in the deciphering of Japanese ciphertext, the master asks you one last time, if you are willing to participate in it. In this job, abide by the secret and never betray the motherland." Hua Luogeng placed the entire black document bag on the table, his face was unprecedentedly solemn. Staring closely at Yu Hua, he said solemnly.

Keep secrets and never betray the motherland.

This is the core requirement of the staff engaged in deciphering Japanese ciphertext.

"Yu Hua is willing to participate in this job, abide by the secret, and never betray the motherland." Yu Hua's face was sacred and solemn, and his clear and divine eyes revealed a hint of firmness, and he said loudly.

"No matter who is 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 a master and a disciple, you know?" Hua Luogeng nodded and said solemnly.

The solemn expression on Yu Hua's face did not diminish at all, knowing that Hua Luogeng's words were not false: "Students remember it."

"This is the original plaintext material in Japan."
