Wu Duan's class was arranged in three or four classes in the morning, in a large classroom, because Wu Duan graduated from the trace examination major, the school required all students majoring in trace examination to arrive, and there were no rigid requirements for the rest of the majors.

The classroom was very full, and there were even students standing in the corridor to listen, which surprised Yan Sixian.

"Aren't you coming back for the first time to give a lecture? So popular, huh? ”

Wu Duan sat in the teacher's lounge and looked down at his phone, "It's not that I'm popular, it's this course, after all, the practical course is liked by the students, and besides, ......"

He looked up and found that the teachers had gone out one after another, and the grade director who was very addicted to smoking also slipped into the bathroom to enjoy himself, so he whispered: "Besides, the people who come to this course have a little real power in the public security system - for example, I, I came for Zhao Ju, and he was originally scheduled to take this class - perform well in class, maybe you can leave a good impression on the future leaders, and assign work or something in the future - although the probability is very low, but it is always a hope."

Wu Duan smiled, "No way, it's not easy for us ordinary people to have a chance, unlike you, a big taxpayer." ”

"Yo, there are thorns in the conversation early in the morning, and you can't digest it after eating too much?" Yan Sixian glared at Wu Duan, he didn't like to be talked about by his wealth, so he used a particularly unworthy sentence, "It's not my father's fault that I have money, if the police don't do a good job, I have to go home and inherit a huge amount of property, and I'm also under a lot of pressure, okay?" ”

However, the other party was Wu Duan, and after opening the taunt skill, Yan Sixian realized that the other party should be unintentional and felt a little guilty.

Fortunately, Wu Duan ignored him and just looked down at his phone.

Yan Sixian was a little speechless, "Hey, are you nervous?" ”

"Are you nervous?" Wu Duan asked rhetorically.

"Not really."

However, Wu Duan's eyes have already conveyed the meaning of "everyone is the first time, and it is normal to be nervous, Comrade Xiao Yan".

Yan Sixian: Okay, I'm nervous.

Wu Duan handed him the phone, "I recently found a way to relieve tension. ”

“？”

"Well, have you watched "Reckless Detective"?"

"It was written by the author of the stupid fork who added a paragraph of martial arts to the mystery story?"

Wu Duan: "Be careful when you speak, I still want to live a few more chapters."

Yan Sixian: "Oh."

Wu Duan and Yan Sixian already have their own funny physique, the two cooperate tacitly, plus the selected cases are very representative, there is room for extended discussion, the students actively participate in the interaction, and the classroom effect is very good.

Before the end of class, there is a session where students can ask questions to the teacher by handing them a small note, and after Wu Duan gets the note, he can choose interesting questions from them.

After the class was over, they coped with the politeness of the school to leave two people for dinner, and the two drove away, and Yan Sixian in the co-pilot seat kept staring at Wu Duan.

"I have rice grains on my face?" Wu Duan asked.

"Take it out, I'll take a look." Yan Sixian stretched out his hand.

"What?" Wu Duan pretended to be stupid.

"Mobile phone number or room number?"

"You, you, you......!" Yan Sixian's direct exposure made Wu Duan embarrassed.

These eyes are too sharp! Wu Duan hurriedly took out a small note from his trouser pocket and threw it to Yan Sixian.

"It's really a mobile phone number," the next second, after reading all the contents on the note, Yan Sixian said loudly: "That girl obviously wrote it to me!" You're also cutting off your beard?! Old Wu, I despise you! ”

"Who's going to cut off this?! I'm here to help you avoid making mistakes and nip the possibility of making mistakes in the bud. ”

"I thank you," Yan Sixian deliberately teased him, "Maybe people really have academic issues to discuss with me." ”

Wu Duan thought about it, "That's right, then you can take it." ”

Yan Sixian: The brain is a good thing, do you want to know about it?

Wu Duan obviously turned over this matter, and said with emotion: "It's almost the Dragon Boat Festival, I hope there will be no more cases in the next two days."

Yan Sixian glanced at him, "It's okay if you don't say it, you open your mouth and say it......" He shook his head, "Tut-tut......"

Before the Dragon Boat Festival, Yan Sixian received a call from the city bureau in the middle of the night.

Hanging up the phone, he gently pulled his arm out from under the neck of the person next to him and walked out of the bedroom.

As soon as he came out, Wu Duan called again.

"Did you notify you?" Wu Duan asked.

"Well, there was a murder in the nightclub, there were two dead people in the bathroom, a man and a woman, the reporter was the manager of the nightclub, it is said that the conditions at the scene were not very good, and many guests went in and out of the bathroom to watch......"

At first, Yan Sixian's voice was still a little sleepy, talking about the case, and the sleepiness gradually disappeared.

Wu Duan's voice was completely sleepy, and he only said, "You don't have to worry, I'm already on the scene." ”

"So fast?!"

Yan Sixian was very surprised, you must know that the crime scene in the city center is at least half an hour's drive away from Yan Sixian's rented house, which is relatively close to his home.

"I was called out by my classmates at night and drank two glasses together, but I didn't expect to encounter a murder."

Yan Sixian couldn't help but smack his tongue, thinking to himself that you are really Conan physique.

"Okay, got it, I'll go out."

"Are you home?" Wu Duan asked without saying anything.

"Or else? What's wrong? Yan Sixian was a little puzzled by his question.

"It's nothing, it's just that the woman died...... Wu Duan paused, "Forget it, let's talk about it when you come." ”

Wu Duan's abnormality made Yan Sixian a little anxious, and he rushed to the scene of the crime as quickly as possible.

95 degrees.

The name of the bar where the crime occurred.

If you look at the degree, you can see that this place is quite restless, and the lights in the bar are dim, even if all the lights are turned on, it is still dim.

The guests have all been cleared, leaving a mess of cups and plates.

There was a big dance floor in the center of the bar, and Yan Sixian even saw a pair of leopard print women's underwear in the corner of the dance floor.

"Tsk, play so big?" Yan Sixian retracted his gaze and walked to the bathroom where the body was.

It was the men's bathroom in the bar, the door was open, and when there was still some distance, Yan Sixian saw Wu Duan squatting in front of a cubicle, not knowing what traces were on the ground.

When he approached the bathroom, he glanced at the face of the deceased woman.

"How is she?!"

Yan Sixian remembers very well that during class this morning, it was this girl who handed him a note and left a phone call, if it weren't for his sharp eyes, he really wouldn't have found out that the note was cut off by Wu Duan.

At this moment, he finally understood what Wu Duan meant by asking him on the phone if he was at home.

This girl is dead now, and she is still in a nightclub, no matter how you look at it, this is a place where Yan Sixian will go in and out.

Wu Duan suspected that he had asked the girl to such a place, but it was understandable.

Yan Sixian immediately said: "I'll go home as soon as I get off work today, the community monitoring, the hotel staff who brought me dinner, and ...... Belch...... The female doctor you met last time can attest to her that she should still be in my house now. ”

"Well, my name is Xiaoxiao and I've checked the surveillance of your community, don't you mind?"
