Once Tong Ju leaves, there will be no tigers in the mountain, and the monkey will be the king. Anyway, this is Li Zan's home court.

He pushed the whiteboard to the center, wrote the words '2nd Generation Crocodile' under Liu Chao's name, closed the pen cap and asked without looking back: "Has Wei Ming taken drugs?"

Zhong Xueru: "No."

Li Zan: "Did Wei Ming and Liu Chao not know each other at all before this?"

Chen Jie immediately said: "We asked Wei Ming's mother, boyfriend and her classmates, and they all said they had never met Liu Chao before. We also checked the communication records of the two people, and the results showed that they did not know each other. And one of them was

One is a student at a prestigious university with a bright future, and the other is a drug addict suffering from cancer. They are two different classes of people."

"It's basically impossible to have any intersection."

There are actually clear distinctions between classes. If the classes are too far apart, it will be difficult for them to interact with each other.

Ji Chengling continued: "Wei Ming is an academic, and her social circle is not wide. Her good friends are basically classmates from the same circle. Interpersonal relationships are very simple, and she spends all day in the laboratory, so she has no chance to have disputes with others."

Lao Zeng: "Wei Ming has a boyfriend?"

"Yes." Ji Chengling opened the information: "Wei Ming's boyfriend is called Cheng Ke, who is 5 years older than Wei Ming and is 29 years old this year. He is a student at Guangdong Medical University and worked as a surgeon at Mingwan tertiary hospital after graduation.

Doctor, due to his excellent skills, he was promoted to chief physician at the beginning of spring."

"A year ago, Cheng Ke and Wei Ming met at the alumni exchange meeting of Guangdong Medical University and Yuejiang University. They had a good impression of each other. After that, they met by chance for half a year. After half a year, they confirmed their relationship and have been in a stable relationship to this day."

Chen Jie nodded: "It is said that the relationship is very good. This time when Wei Ming had an accident, he immediately asked for leave and accompanied Wei Ming's mother to deal with the accident. Moreover, he also supported the police in thoroughly investigating the truth about Wei Ming's fall."

Lao Zeng opened the documents and said: "It doesn't sound like a love killing. There is no problem with the interpersonal relationship and there are basically no conflicts with others. This can rule out vendetta." He raised his head and asked: "Is there any reason for wealth?"

Ji Chengling: "Wei Ming is a single-parent family. Her mother is highly educated and has opened an early childhood education institution in Dongcheng District. The property should be two to three million, but it is all in the institution, and it is the personal property of Wei Ming's mother.

"

"It's not love killing, vendetta, or killing her for money, so that's the last possibility left." Li Zan knocked on the table rhythmically while looking at the molecular formula of the multimedia light screen '2nd Generation Crocodile' and said: "She understands.

A secret that shouldn’t be known, so it was silenced.”

This is the most current speculation that is in line with the development of the case.

Excluding the three most common causes of murder: love, hatred, and money, and combined with Liu Chao's analysis results, it can be inferred that he murdered Wei Ming to silence him.

Before Wei Ming was taken away on a stretcher by an ambulance, the two words he cried out in tears were "crocodile".

Liu Chao was a desperado and had taken a new type of drug similar to 'Crocodile' before his death.

The marker turned flexibly between Li Zan's fingers. He thought while saying: "The reason why Wei Ming was silenced may be that she knew a secret, which was related to the new drug 'Crocodile'."

How could Wei Ming, an ordinary college student, get involved with new drugs? How did she discover new drugs with simple interpersonal relationships?

"She's a chemistry student?"

Ji Chengling nodded: "I have been admitted to the graduate school. I could have entered the Institute of Chemistry of Guangdong University in March."

Hearing this, everyone present who knew the situation was in an uproar.

"How awesome is the Institute of Chemistry of Guangdong University?" Chen Jie asked as she didn't understand.

"It's very awesome." Zhong Xueru heard the words and answered: "But it is a private research institute affiliated to Yuejiang University, and it usually keeps a low profile. It has a good reputation in the industry. It has worked on several projects before, and the feedback has been very good.

Good."

He continued: "Wei Ming was admitted as soon as she was admitted to graduate school, which proves that her level has passed the test."

Lao Zeng asked Li Zan: "Do you suspect that Wei Ming's death is related to her being a student in the Department of Chemistry and the Institute of Chemistry?"

Everyone looked at Li Zan after hearing this. They all knew that drug manufacturing and chemistry were inseparable.

There are many cases of middle school chemistry teachers making drugs and university chemistry teachers using laboratories to make drugs. A random search on the Internet will bring up a bunch of news links.

"If there is no problem with Wei Ming's interpersonal relationship, then start with her work environment and study environment." Li Zan wrote the words 'research institute' on the whiteboard and said at the same time: "Wang Dangdang, please check this private

The institute’s past. Dig deeper.”

After a pause, he added: "If there is really a problem, it must be hidden deep."

Wang Dangdang said that technology has never been a problem: "What should I do if I cross the border?"

When Li Zan heard this, he took off the cap of the marker pen and threw it directly: "Stop pretending to be good in front of your father. Don't think that I don't know how many servers you have installed in your home."

The cap of the pen hit Wang Dangdang's forehead. He immediately wrinkled his face and lowered his shoulders dejectedly: "There are only two servers, a new model that has just arrived."

Li Zan was too lazy to fight for bones with this it dog. He then said to the others: "Both sides have to investigate. Wei Ming has to investigate, and Liu Chao has to investigate. Let's start with his interpersonal relationships.

It’s—”

"He spent money at a spa shop on Hang Shui Street in early February?"

This information was checked by Wang Dangdang, and Li Zan not only read it, but also mentioned it just now. But he mentioned it again, indicating that it is somewhat interesting.

Wang Dangdang: "What?"

Li Zan raised his eyebrows: "I just think it's quite a coincidence."

——The big gold chain brother who fell under the banner of anti-pornography.

..

Dongcheng District branch hall.

People were coming and going in the hall, and from time to time someone would hurriedly step onto the police car parked at the door with a folder in hand, turn on the red and blue lights and drive away.

Those who committed crimes were released on bail by their families. Some pointed and cursed all the way, some were extremely disappointed in silence, and some just said "take the right path from now on" and didn't speak. Those who were taken out were red.

There was a look of remorse in his eyes.

There are only crying and laughing in the world, except for the hospital and the police station.

Wei Manjun squeezed her leather bag tightly, her fingers turned white, and her face and lips almost blended into the blue-white color of the wall. Her eyes were dull, and when she saw Li Zan and his group coming out, she recognized Ji Chengling and others among them.

Chen Jie.

She rushed over and grabbed Ji Chengling as if no one was watching: "Comrade police, is there any progress in my daughter's case...?"

The short, low-volume words seemed to exhaust all her strength, as if her lungs were torn apart and blood foam soaked into her throat, and there seemed to be a strong smell of blood as soon as she opened her mouth.

Li Zan stopped, turned around and looked over.

Chen Jie was surprised and whispered: "Wei Manjun, Wei Ming's mother."

Wei Manjun, 49 years old, looks like she is in her thirties. She was originally beautiful, intellectual, and had the gentle temperament of a teacher. However, after the sudden death of her daughter, she declined rapidly in just half a day.

Ji Chengling consoled her nicely: "We are investigating and it is not convenient to reveal the progress of the case to the public."

Wei Manjun hissed with trembling lips: "Mingming and the person who killed him didn't know each other at all. There must be a real murderer behind the scenes! The murderer killed my Mingming, and 'he' must have seen Mingming's death... You want

Catch him, be sure to catch him! Then ask him, remember to ask him, no grudges, why did you kill my Mingming?!"

"Why did you kill her so cruelly?! Do you know how painful it was before she died? Her ribs were inserted into her lungs and heart, and her blood flowed backwards. Her mouth and nose were all covered in blood!"

"My Mingming, it hurt so much before she died."

Li Zan pursed his lips and whispered to Chen Jie: "Go comfort her and calm her emotions."

"Okay." Chen Jie stepped forward to help Wei Manjun: "Ms. Wei, all our comrades in the criminal investigation department are investigating this case. The inside information is not disclosed to the public for the time being. But we promise that we will investigate it to the end!"

Wei Manjun grabbed Chen Jie's wrist tightly and stared at her for a long time: "I heard you, you... do what you say."

Chen Jie nodded heavily and made a promise: "We promise!"

Her wrist was tightly held and it hurt a lot. She couldn't help but think that Ms. Wei looked gentle and weak, but she was really strong.

Then I thought again, if the daughter who depended on each other died so tragically, it would be reasonable for her to explode in pain.

Wei Manjun slowly let go of her hand and took two steps back. His shoulders suddenly collapsed, and his spine, which had been straight and elegant for decades, suddenly became rickety.

Her eyes were panicked, and she whispered a few words: "Comrade police, thank you."

Chen Jie couldn't help but feel sad when she saw the changes before and after with her own eyes, and comforted her with a warm voice.

Li Zan watched from the sidelines, touched the cigarette case in his pocket with his fingertips, took out a cigarette, rubbed the butt of the cigarette and thought about it but still didn't take it out.

He didn't urge Chen Jie to delay, nor did he signal Ji Chengling and the others to follow him. Instead, he waited quietly and patiently.

At this time, a young man came in carrying water and porridge. As soon as he saw Wei Manjun, he rushed over anxiously and worriedly: "Auntie, how are you? Drink some water first and fill your stomach." He squeezed the water to open the lunch box and looked attentively.

While taking care of Wei Manjun, he did not forget to politely thank Chen Jie and the others: "Sorry to trouble you, comrade police."

Li Zan put one hand in his pocket and recalled that when this man passed by him just now, he smelled the strong smell of disinfectant alcohol coming from his body.

"My name is Cheng Ke, Wei Ming's boyfriend." Cheng Ke introduced himself. After Wei Manjun's mood stabilized, he picked Li Zan, who had been standing not far away, and asked in a low voice: "Hello, comrade police, I want to ask

Ask the person who killed Wei Ming why—"

"Why did he want to kill Wei Ming?" Cheng Ke couldn't hide his confusion and anger: "He was basically murdering deliberately!"

Li Zan: "Ms. Wei thinks someone hired Liu Chao to kill Wei Ming."

Cheng Ke was stunned: "Liu Chao?"

Li Zan: "The person who killed Wei Ming."

Cheng Ke: "Is there any evidence?"

Li Zan: “Not yet.”
