Take all the paper items?

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

Central University did undertake some national defense projects, but as far as he knows, lower-grade students like Yuan Chuyu are not among the researchers. Could it be that something went wrong?

After thinking about it over and over again, Zuo Chong felt that he wanted to talk to the school and Yuan Chuyu's mentor. The scene couldn't run away here. He had to determine why the suspect was interested in Yuan Chuyu's items as soon as possible. If you figure it out, the case will be clear.

Faced with the request of the Deputy Director of the Military Intelligence Bureau, 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 tutor, Xu Kang, professor of the Department of Mathematics of Central University.

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

Seeing Xu Kang's reaction, the vice principal was angry and anxious. He quickly asked Zuo Chong to sit down, then poured a cup of hot tea and put it on the table, and whispered to introduce Xu Kang's background.

"Professor Xu is from Suzhou Province. After graduating from Cornell University in the United States a few years ago, he went to teach at Central University. His professional level is very high."

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

"Hello Professor Xu, I am Zuo Chong, deputy director of the Military Intelligence Bureau. Today I visited for the disappearance of your student Yuan Xinyu. I wonder if you have any clues to provide?"

Warned by the vice principal's eyes, Xu Kang had to put down the book in his hand, sit there and frown and think about it, and then slowly shake his head.

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

Logically speaking, a student encounters this kind of thing simply because of emotional and financial disputes. Director Zuo, I think you can follow these two points to check it."

Zuo Chong met the person involved in the case who taught him how to investigate the case for the first time. He smiled faintly and did not take the matter seriously. Then he turned to look at the vice president and asked what defense projects the Central University had undertaken, especially those related to the Department of Mathematics.

This is the most prone to problems. Although the national government is weak and the overall technological level is large compared with Western developed countries, the Republic of China still has a certain leading position in certain specific fields and majors.

Such as 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 1930s to 1940s, a familiar mathematician in later generations achieved a series of important achievements in the fields of number theory, complex number analysis, and made his mark in the international mathematics community.

If Yuan Xinyu has been exposed to certain sensitive projects, the project may have been targeted. As an intelligence agency, the Military Control Commission must take some action.

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

"In order to support the War of Resistance and National Defense Construction, we undertake a number of national defense research projects, covering multiple fields, including engineering, chemistry, physics and biology.

Such as improving the stability and power of gunpowder, weapon design and improvement, research on anti-virus and 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 Chen Dongxin of the Central Commission for Discipline Inspection has given instructions that all personnel participating in the project must be strictly identified, and they must have food and accommodation separately to prevent secret leakage.

Yuan Xinyu has just entered the school and is definitely not qualified to join the research project. Besides, he is extremely active on campus and knows too many people, so he is not suitable for secret research."

Zuo Chong quickly passed the information he said in his heart. It is not surprising that the Zhongtong appeared in this matter. They themselves have the responsibility to identify important personnel in the agency, but if so, what would be the problem?

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

"Some, Professor Xu has participated in the formulation of diplomatic telegram codes of the Ministry of Foreign Affairs and the deciphering of Japanese diplomatic telegrams."

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

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

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

Zuo Chong was full of question marks. If I had understood these things, would I have to be a private detective in my previous life? Is it better to go to the big factory 996?

Seeing his face dull, Xu Kang sighed, feeling that he was playing the piano for a cow, so he had to explain it in a more understandable language.

"The Ministry of Foreign Affairs has intercepted a large number of Japanese encrypted telegrams. After preliminary analysis of these telegrams, we noticed that the encrypted information contains certain repetitive patterns, which are related to the structural characteristics of Japanese.

And I am responsible for this research. I know what you mean by Deputy Director Zuo, but I can be sure that I have not disclosed the secrets to anyone, and even if I say it, those people will not understand it."

Speaking of this, Xu Kang's mouth was slightly raised, and the sarcasm was beyond words, which scared the vice principal.

Where is the Military Control Commission? Dead people have to speak when they enter. If they anger the Zuo person, not only Xu Kang, but also he cannot see the sun tomorrow.

This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! Zuo Chong stared at Xu Kang and roared in his heart, MD, this guy looked down on me! Is it great to understand advanced mathematics? Well, it's really great.

But if you point at the monk and scold the bald, that's your fault. The minds of these scholars are really dirty.

After a cold face, Zuo Chong was about to get up to say goodbye. Wu Chunyang walked in from outside the door and approached his ear to report a new situation.

"Second post, Yuan Xinyu's classmates have important clues to reflect."

Zuo Chong glanced at Xu Kang deeply and walked out strode. He kept telling himself that there were many adults and not to be as knowledgeable as a nerd. He kept walking to the temporary questioning room under his feet.

In the room, a young student wearing glasses saw the two people entering the door, immediately jumped up from the stool and asked nervously.

"Okay, just say it, what do you have to react to?" Zuo Chong went straight to the point, not interested in listening to the other party's nonsense.

The student stumbled twice and plucked up the courage to speak: "Report to the lord, Yuan Chuyu and I are in the same house. Those people stole the money I put on the desk. Can you help me find it back?"

Perhaps because I thought it was a bit ridiculous, the student quickly added: "I am poor, and the money was earned by my mother sewing clothes for others with one stitch and one thread. Please understand."

This is the so-called important clue?

"Come on me to get him away!" Zuo Chong was so angry that he waved his hand to the spy again: "Forget it, register the number and record a confession for him."

Looking at the students being pushed out, Wu Chunyang informed the survey results of the dormitory.

Around Yuan Chuyu's bed, technicians failed to extract valid clues such as fingerprints. The suspect should have worn gloves when acting and acted cautiously.

In addition, the simulated portraits drawn based on the oral description of witnesses have been painted and can be distributed to the police and Ge Lao Association for a large-scale search. Wu Chunyang asked whether to disclose the portrait.

Zuo Chong was not surprised to see the first result. Not to mention intelligence personnel, even experienced thieves can steal without leaving any trace.

As for the public simulated portrait, he hesitated for a moment and did not immediately decide. He had to see what the result of Gui Youguang's pursuit was.

Whatever he said came, a small spy came in to report, and the pursuers lost their target by the river and told them the specific location of the lost.

Zuo Chong asked Wu Chunyang to stay and continue the investigation, and found a way to figure out the list of paper items taken away by the suspect, and got in the car and went to the riverside by himself.

Half an hour later.

The Jialing River was extremely lively. Teams of small spies were searching on both sides of the strait with flashlights. There were loud and loud machine boats everywhere on the river. From time to time, people on the boat threw fishing nets with barbed hooks into the water and dragged them down to patrol the boat.

Behind a dirt slope on the shore, Gui Youguang squatted beside a black Buick covered with bullet holes. On the left side of the back seat, there was a white-soaked corpse looking forward quietly, looking a little scary.

Not far from his feet, there was a corpse lying on the ground, with several holes on his chest, and it was also brewed by the river without a trace of blood.

"Second post."

"Second post."

Hearing the sound coming from behind, Gui Youguang turned around and saw Zuo Chong coming, and ran to Zuo Chong and walked and said.

"Two bodies were found on the scene, and no documents were found on them. The police uniforms they wore were imitations, but the stitches were meticulous and the hat badge was very fine. Ordinary gang members did not have such imitation level.

Judging from the traces inside the car, there should have been four people in the car before, two people who had escaped, one of the two people who escaped had a piercing injury on his left arm. I have asked him to go to various hospitals to guard him."

While speaking, the two of them came to the right rear door of the Buick car, put on gloves and opened the door, and shone the flashlight into the carriage. They saw a body with no eyes closed.

The other party was a standard yellow man with strong muscles and no other information was analyzed from the appearance alone. Zuo Chong looked up at Jiang and said to Gui Youguang.
