I saw him looking around at the corpse, as if he was looking for something. After a while, he found two hairs from the cuffs of the corpse.

After taking the ziplock bag that had been prepared a long time ago, Fang Lubai carefully put the hair into it.

Since it was a corner between the two shops, a lot of debris was piled up around the deceased. Fang Lubai took the murder weapon in his hand and thought secretly in his heart.

The murder weapon was a sharp knife 15 centimeters long, the blade of the knife was only about 4 centimeters wide, but the metal at the handle was much wider than the blade, the sharp knife was sharpened to a shiny point, and the thin blade reflected the early morning sun.

"Take this murder weapon as a breakthrough, this is a meat cleaver, surrounded by a tube building, it is estimated that there is no monitoring, the murder weapon has been used for a long time, the knife is very narrow, the murderer should have stolen it from a butcher shop or slaughterhouse."

"I said, why are you still gone......" He leaned over again and placed several comics on the table.

"Look at it, these are all new arrivals, and some of them may not even be available in bookstores!" He proudly sold it, Fang Lubai really wanted to see the same.

"Sorry, I don't need to!" Fang Lubai replied indifferently, and then changed his position.

The student behind "Cut ......" also returned to his place with a disdainful face.

"The students in the back, don't you know that you can't run around casually during class?" At the podium in front of him, there was a crisp sound, and then, Fang Lubai felt that something had hit his head.

I touched the collar and realized that it was a piece of chalk.

The students who were sitting in the front and listening carefully saw that the teacher was a little angry, and they also looked back at the back row, and suddenly, Fang Lubai became the focus of the class.

After a while, a voice came from the front: "Teacher, this classmate is not from our Normal University, he is an auditor!" ”

As soon as the words fell, the other students lowered their heads and whispered about Fang Lubai behind them.

Fang Lubai sighed and said in a deep voice to the teacher on the podium, "Teacher, I'll pay attention next time." ”

"Okay, although we have no objection to auditing, but sitting in the class, I hope you can abide by the discipline in the class, okay, the heart is continuing to class."

Seeing that the teacher did not continue to make difficulties, the students stopped looking over their heads and looked at the knowledge points on the blackboard again.

The end of class was fast, and listening to the melodious ringtone, the teachers and students showed a relaxed look on their faces.

"Okay students, this class is here first, and the knowledge points taught in class must be reviewed when you go back, and the questions for the exam are all in it!"

The students nodded, and she walked out of the classroom with confidence.

"Hey, I said that you are an auditor and quite eye-catching, and you know how to take the initiative to erase the blackboard!" The thief-eyed student just now looked at Fang Lubai curiously.

Fang Lubai was carefully wiping the blackboard, but he didn't expect to have a hand on his shoulder.

"Hey, buddy, the next class is "Behavior", Mr. Zhai has already gone home from vacation, what's the use of you wiping the blackboard?"

"That's... Won't you come up in the next class? Fang Lubai pretended not to know and asked him.

"Who knows." He pouted: "Perhaps, Teacher Han will come to watch the self-study in the next class, and it was like this last week." ”

The end of class was only fifteen minutes, so the students had already seen the time to run back to the classroom. Looking at the student who was chatting with him just now, Fang Lubai called out with some uncertainty: "Are you called Zhou Chuang?" ”

"How do you know?" Zhou Chuang, who was flipping through his notes, looked at Fang Lubai with a curious expression.

"Last time, I listened to Mr. Han's class."

As soon as the words ended, the class bell rang. The students closed their mouths one after another, and the corner of their eyes swept towards the door from time to time.

"Hey, what's going on? Not down yet? Teacher Han should be here in a moment! Zhou Chuanghu, who was sitting below, looked at Fang Lubai suspiciously, as if he was a little puzzled by his actions.

I saw Fang Lubai put his schoolbag on the table, and slowly took out the water cup and teaching materials.

"Hello students, my name is Fang Lubai, because Teacher Zhai Hui can't continue to take you to class because of something temporary, so the school has decided that I will temporarily take over Teacher Zhai's class, I hope you will take care of it."

The students below looked at Fang Lubai with an incredible look.

"Hey, I said you don't mess around. Teacher Han is here in a while, you hurry down! Zhou Chuang said a little anxiously.

"I'm a substitute teacher, what if he comes?" Fang Lubai looked at Zhou Chuang in the audience curiously.

"You hurry up and ......," Zhou Chuang said as he jumped up from his chair.

Before he could walk up to the podium, a figure came to the door. I saw Han Tian walking towards the classroom with a glass of water with a leisurely face, and Zhou Chuang, who was about to rush to the podium, froze in place, his face was a little ugly.

"Teacher, this is actually the way things ......"

"Oh, Fang Lubai, so you're here, I thought you didn't have time to come!" Han Tiangang walked to the door and saw Fang Lubai standing on the podium preparing for class, so he smiled and nodded.

"Well, there is nothing to do with me over there for the time being, I can't let go of my students!" Fang Lubai responded to him.

As soon as his eyes turned, Han Tian noticed Zhou Chuang on the side, so he said a little sternly: "Zhou Chuang, what are you doing there, don't you know that you have already taken class?" As a class leader, what does it look like to mess around during class time! ”

What did I remember that the squad leader named Zhou Chuang was still standing in front of the podium, looking at the two of them with an embarrassed expression.

"Teacher Han, I'm ......" Zhou Chuang wanted to drag this undisciplined student down quickly, but listening to the conversation between the two, could it be that this auditor was really his substitute teacher?

Looking at Han Tian with a serious face, Fang Lubai hurriedly came out to play a round: "This classmate just wants to help me check the attendance of the students." ”

"Yes, yes, Mr. Han, I want to see the attendance of our class." Seeing that Fang Lubai was actually covering for himself, Zhou Chuang nodded again and again on the side.

"Okay, you have a good class, and I'll look for you when I take a lunch break." After finishing speaking, Han Tian turned around and disappeared from everyone's sight.

"Forehead ......"

After Han Tian left, the class was very quiet, looking at a group of stunned students, Fang Lubai put the textbook in his hand on the table.

"Hey, why did you go back? Didn't you say okay to check my attendance? ”

Zhou Chuang, who was originally standing on the side, was lowering his body at this time and slowly walking towards his seat. Seeing his cautious look, Fang Lubai hurriedly stopped him.

This classmate ...... No, teacher, I ...... I'll go back and get the roll call. Zhou Chuang glanced at Fang Lubai with some embarrassment.

"Okay, you go get some rosters first."

Then he took out a thin pamphlet from the table and went to the podium with an embarrassed expression.

"Why are you still stunned? Please start your show! Fang Lubai said to him with a smile.
