Chapter 1242: Being Despised

Took away all paper items?

After listening to Wu Chunyang's report, Zuo Chong frowned. A group of well-trained suspects took such a big risk to impersonate police officers just for a student's textbook and homework?

Central University did undertake some national defense projects, but as far as he knew, junior students like Yuan Chuyu were not among the researchers. Could something have gone wrong?

After thinking it over again and again, Zuo Chong felt that he should talk to the school and Yuan Chuyu's instructor. The scene was right here and he couldn't escape. He had to determine as soon as possible why the suspect was interested in Yuan Chuyu's belongings. Once this was figured out, the case would become clear.

Faced with the request of the deputy director of the Military Control Commission, the school did not dare to neglect it. A vice president in charge of the Department of Mathematics came forward and led Zuo Chong to meet Yuan Xinyu's mentor, Xu Kang, a professor in the Department of Mathematics at Central University.

Professor Xu was neither disgusted nor enthusiastic about the spy's visit. He slowly stood up from the rattan chair behind his desk and shook hands with Zuo Chong.

Seeing Xu Kang's reaction, the vice principal was both angry and anxious. He quickly asked Zuo Chong to sit down, and earnestly poured a cup of hot tea on the table, while whispering about Xu Kang's background.

"Professor Xu is from Jiangsu Province. He graduated from Cornell University in the United States a few years ago and joined Central University to teach. He has a very high level of professionalism."

After listening to this, Zuo Chong nodded, looked at Xu Kang who had already sat down, a smile appeared on his face, and he took the initiative to chat with him.

"Hello, Professor Xu. I am Zuo Zhong, deputy director of the Military Control Commission. I am here to visit you today regarding the disappearance of your student Yuan Xinyu. Do you have any clues to offer?"

Under the vice-principal's warning look, Xu Kang had to put down the book in his hand, sat there frowning and thinking, then slowly shook his head.

"Yuan Xinyu is a very diligent and smart student. He often comes to my office to ask me questions about my major. Apart from that, I don't have much personal communication with him.

Logically speaking, a student encounters this kind of thing, it is nothing more than emotional and financial disputes, Director Zuo, I think you can investigate along these two points. "

It was the first time that Zuo Zhong met a person involved in a case who taught him how to investigate the case. He smiled faintly and did not take the matter to heart. Then he turned his head to look at the vice president and asked what national defense projects Central University had undertaken, especially those related to the Department of Mathematics.

This is where problems are most likely to occur. Although the national government was weak and the overall scientific and technological level was far behind that of Western developed countries, the Republic of China still had a certain leading position in certain specific fields and professions.

For example, archaeology and paleontology, agricultural technology, traditional Chinese medicine, geology, mathematics, railways and civil engineering, epidemic prevention and public health.

Taking mathematics as an example, from the 30s to the 40s, a well-known mathematician in later generations achieved a series of important results in the fields of number theory and complex number analysis, and made his mark in the international mathematics community.

If Yuan Xinyu had been exposed to certain sensitive projects, then this project might have been targeted by someone. As an intelligence agency, the Military Control Commission must take action.

When the vice principal heard Zuo Zhong's question, he did not answer rashly, but thought about it carefully for a long time before giving an answer.

"In order to support the war of resistance and national defense construction, we undertook a number of national defense scientific research projects, covering a variety of fields, including engineering, chemistry, physics and biology.

Such as improving the stability and power of gunpowder, weapon design and improvement, research on anti-poison and anti-chemical weapons, optimization of radio equipment, and intelligence and cryptography technology.

These are all related to mathematics. After all, mathematics is the mother of science. However, Director Shen Dongxin of the Central Bureau of Investigation and Statistics has instructed that all personnel involved in the project must be strictly screened and have separate accommodations and meals to prevent leaks.

Yuan Xinyu has just entered the school, so he is definitely not qualified to join the research project. Moreover, he is very active in the school and knows too many people, so he is not suitable for conducting secret research. "

Zuo Chong quickly went over the information the other party had said in his mind. It was not surprising that the Central Bureau of Investigation was involved in this matter. They had the responsibility to identify important agency personnel. But if this was the case, where would the problem lie?

He looked at Xu Kang next to him and asked the vice president another question, whether Xu Kang participated in the research project. The vice president looked embarrassed, glanced at Xu Kang and replied in a low voice.

"Yes, Professor Xu participated in the formulation of the diplomatic telegram codes of the Ministry of Foreign Affairs and the deciphering of diplomatic telegrams to Japan."

Seeing that he was involved in the matter, Xu Kang could no longer remain silent. He picked up the teacup, drank a sip of hot tea, and said a lot of confusing words.

“Mathematics is not only a basic tool in scientific research, but also a key driving force for scientific progress. It provides scientific research with rigorous logic and precise tools, enabling us to more deeply understand the complexity of the natural world.

For example, cipher machines have complex circuits and rotating disk systems, which result in the password generation process having certain linear characteristics. We can use linear algebra methods to analyze the behavior of these circuits and rotating disks and infer some password generation rules. "

  ? ? ? ?

Zuo Chong was full of question marks. If I knew all this, would I have been a private detective in my previous life? I should have gone to work in a big company, working 996 hours a long time ago.

Seeing his dazed face, Xu Kang sighed and felt like he was talking to a cow, so he had to explain it again in more understandable language.

"The Ministry of Foreign Affairs had intercepted a large number of Japanese coded telegrams, and after a preliminary analysis of these telegrams, we noticed that the coded messages contained certain repetitive patterns that were related to the structural features of the Japanese language.

I am responsible for this research. I know what you mean, Deputy Director Zuo, but I can be sure that I have not disclosed any secrets to anyone, and even if I did, those people would not understand. "

At this point, Xu Kang's mouth curled up slightly, and his sarcasm was evident in his words, which scared the vice-principal.

What kind of place is the Military Control Commission? Even the dead have to speak in it. If they anger the guy named Zuo, not only Xu Kang, but also he will not see the sun tomorrow. Zuo Zhong stared at Xu Kang and roared in his heart, MD, this guy looks down on me! Is it great to know advanced mathematics? Well, it is indeed great.

But you are wrong if you point at the monk and call him bald. These scholars are really filthy-minded.

After a moment of sullen silence, Zuo Chong was about to get up and say goodbye when Wu Chunyang walked in from outside and whispered a new situation into his ear.

"Deputy Commander, Yuan Xinyu's roommate has important clues to report."

Zuo Chong looked at Xu Kang deeply and strode out. He kept telling himself that the adults were magnanimous and not to argue with the nerd, and kept walking towards the temporary interrogation room.

In the room, a young student wearing glasses saw the two people come in, immediately jumped up from the stool, and greeted them nervously.

"Okay, just say it directly. What do you want to respond to?" Zuo Zhong went straight to the point. He was not interested in listening to the other party's nonsense.

The student stammered twice, then mustered up the courage to speak: "Sir, I live with Yuan Chuyu in the same dormitory, and those people stole the money I left in my desk. Can you help me find it back?"

Perhaps he himself found it a little ridiculous, so the student quickly added: "My family is poor, and this money is earned by my mother sewing clothes for others. Please understand."

Is this the so-called important clue?

"Get him out of here!" Zuo Zhong was furious, but after thinking for a moment, he waved his hand at the little spy and said, "Forget it, just record the amount and then record his statement."

Looking at the students being pushed out, Wu Chunyang reported the results of the dormitory inspection.

Technicians were unable to extract any effective clues, such as fingerprints, around Yuan Chuyu's bed. The suspect must have worn gloves and acted very cautiously.

In addition, a simulated portrait based on the witnesses' oral statements has been drawn up and can be distributed to the police and the Gelaohui at any time for large-scale manhunts. Wu Chunyang asked whether the portrait should be made public.

Zuo Chong was not surprised by the first result. Not to mention intelligence personnel, even experienced thieves could steal without leaving any traces.

As for publishing the simulated portrait, he hesitated for a moment and did not decide immediately. He had to wait and see the results of Gui Youguang's pursuit.

As expected, a small spy came in and reported that the pursuers had lost their target by the river, and he also gave the specific location where they lost the target.

Zuo Zhong asked Wu Chunyang to stay and continue the investigation, and try to find out the list of paper items taken away by the suspect, while he got in the car and headed for the river.

After half an hour.

The Jialing River was unusually lively. Teams of young spies with flashlights were searching on both banks. The river was full of motor boats making rumbling sounds. From time to time, people on the boats would throw fishing nets with barbed hooks into the water and patrol back and forth while being towed by the boats.

Behind a slope on the shore, Gui Youguang was squatting next to a black Buick riddled with bullet holes. On the left side of the back seat, there was a whitish corpse that looked quietly forward, looking a little scary.

Not far from his feet, there was another corpse lying on the ground with several holes in the chest, which was also soaked by the river water without a trace of blood.

"Vice seat."

"Vice seat."

Hearing the voice behind him, Gui Youguang turned around and saw Zuo Chong coming. He trotted over to Zuo Chong's side and talked as he walked.

"Two bodies were found at the scene, with no identification documents on them. The police uniforms they were wearing were imitations, but the stitching was detailed and the cap badges were also finely crafted. Ordinary gang members don't have this level of imitation.

Judging from the traces inside the car, there should have been four people in the car before, two died and two escaped. One of the two who escaped suffered a penetrating wound in the left arm. I have sent people to various hospitals to wait."

As they were talking, the two men came to the right rear door of the Buick. Zuo Zhong put on gloves, opened the door, shone the flashlight into the car, and saw a dead body with its eyes open.

The other person was a typical yellow man with strong muscles. No other information could be analyzed from his appearance. Zuo Zhong raised his head and looked at Jiang Mian and said something to Gui Youguang.

"Take the deceased's photo and the simulated portraits of the other two people and search the entire city. We must find the person alive or dead. Pay attention to safety during the search. I have a feeling that this time we may really meet an old enemy."
