As the minutes ticked by, all the students gathered on the third floor of the Shaw Building, where the lights and ideas were clearly a weighty lecture. The teachers organized on the side were there to manage these many students, not to mention. Dong Shi looked at the students of class 0404 very anxiously, and the whole class was missing me and Ruohan. Dong Shi was ruthless in her heart, and told me in the morning to let me come to class, and I didn't bird her when I turned my head, and it is estimated that Dong Shi's heart was angry.

"Teacher...... Teacher ......"

I gasped and ran in front of Lao Dong, and so did Ruohan, who followed me. And Ruohan couldn't even speak.

"What are you doing again, is it so hard to make you go to class every day?"

Lao Dong began to bombard me with words, and he kept talking, which made me feel a lot more wooden. I hurriedly persuaded, "Teacher, I know it's wrong. ”

My attitude of admitting my mistake was very sincere and serious, and the angry old Dong didn't know what to say all of a sudden. Anyway, when I arrived, Lao Dong just scolded a few words.

A teacher told all the students to enter the room, and the lecture was about to begin.

One by one, the students entered the classroom. Lao Dong said to me at ease as he went inside: "I'll go in for a while, you have to stop and listen carefully." ”

"Okay teacher, I got ......"

I said impatiently, but I thought that I would find a place against the wall for a while, and if it was interesting, I would listen to it, and if it was not interesting, I would use sleep* to mix it up.

It seems that I have been preparing here for a long time, and there is a mature man about forty years old standing in front of the podium, dressed in a MiG suit, and his mouth is not touched, it is estimated that he is talking about something, and I also exclaimed in my heart, this Professor Cheng is so young.

"One, two, three. It's time to go."

In the upper right corner of the classroom, a photographer shouted to Professor Cheng on the podium.

"Ladies and gentlemen, before I start today's lecture on the origin of species, I want to ask you a question, do you know what a living thing is?"

No one answered......

Many people know what a creature is, but why no one answers. I don't know if you have seen the lectures of the professors in the hundred forums, even if it is a question, he will answer it himself. The audience can only listen quietly. This is respect for the speakers on stage.

The professor said to himself: "A living thing is a living organism with kinetic energy, and it is also a collection of objects, and an individual organism refers to a living organism." Its elements include: a living object with viability and reproduction ability that is generated by chemical reactions under natural conditions, and a living offspring produced by it through reproduction. ”

The professor began to talk at length about what living beings are, the origin of biological life...... After I got impatient, I tried to find a way to keep myself from sleepy......

"Biodiversity refers to all the organisms in the Earth's biosphere, namely animals, plants, microorganisms, and the genes and environments in which they live. It contains three levels: biodiversity, genetic diversity, and ecosystem diversity. ”

It's really tormenting for me, I really don't want to listen to it, I'm really not interested in biology at all, what should I do? I really wanted to escape from this course that I didn't want to hear.

Ruohan, who was beside me, slapped me on the arm and said softly: "Just thirty minutes, listen well, or Teacher Dong will scold you again in a while." ”

I nodded slightly, signaling to Ruohan.

And I had to listen quietly, hoping that the time would pass soon.

I don't know how long it has been, my eyes have been watching the professor give a lecture there, but I don't think about Yu Xiaodie's things in my heart, and I suddenly don't know what comes to mind.

"What's going on with this petrified dragon...... Listen to the next ......"

Suddenly the classroom burst into thunderous applause, which also woke me up from the world of ideas. I know it's over......

Everyone applauded Professor Cheng's wonderful lecture, although I don't like biology, but for students who love biology, this is a lesson in knowledge evolution.

Professor Cheng walked out of the classroom cheering, and the TV station staff also left after packing up their equipment. Such a wonderful lecture is over.

Ruohan and I walked quietly on campus, aimlessly. I didn't know where I was going, and I was confused. Ruohan silently accompanied me and walked quietly with me.

"When I was in class, I kept thinking about Yu Xiaodie's case, and for a while, my brain wanted to turn on the green light, but I couldn't remember it...... It's sad......"

When Ruohan saw me speak, he said, "Hey...... You...... A day of ......"

"I don't have a god, I'm talking about the key issue, I did think of something, but I forgot it."

Before I knew it, Ruohan and I walked out of the campus, Ruohan asked me where I was going, and I said go home. Ruohan didn't say anything, but still followed me......

At the entrance of my community, there is a Rongbo supermarket, I often go there to buy cigarettes, and the big brother of the supermarket gets along with me. I have a habit of smoking a few cigarettes when I'm upset and relaxing myself while smoking. Later, the big brother of Rongbo Supermarket gradually learned about my habit, and he liked to tease me whenever I bought cigarettes.

"Big brother, give me a bag of Changbai Mountain."

The big brother of the supermarket, about 50 years old, and his son is almost the same age as me, I don't like to call uncle, uncle, especially when I see this big brother, I have a kind feeling, and I call him big brother unconsciously. And the big brother of this supermarket didn't care much about me, a little kid, what he said he promised.

"Yo...... Little brother, I'm not alone today! And bring a beautiful woman. Isn't it you? ”

As soon as Big Brother said it, I found out. It turns out that Ruohan has been following me all along.

I blushed and smiled, "Don't talk nonsense, she's my classmate......"

"Haha...... If you don't catch up, you say that you are classmates, and if you catch it, you call your daughter-in-law...... This little girl is nice and energetic...... Worthy of your ......"

Ruohan just smiled shyly while listening to Big Brother's speech, and didn't say anything. As for me, I said loudly: "Big brother, don't tease me, she is one of my classmates, hurry up, give me a bag of Changbai Mountain." ”

The big brother in the supermarket smiled and threw me a pack of Changbai Mountain and said, "You kid, you will have such a beautiful object in the future." You're fine, aren't you......"

The big brother in the supermarket said that I blushed for a while and was white for a while.

"I forgot about you while walking, but I didn't expect you to be with me all the time."

"You idiot, what do you mean to accompany you. I'm not your ......"

looked at Ruohan's face flushed...... I don't know what to say.

"You're not mine......" I asked curiously.

"I don't know anything...... I'm at your house again...... Let me go in and do it. ”

I really don't pity the jade, and the beautiful woman won't let me in when she arrives at my door, it's a nerd.

As soon as I entered the house, I said, "Ruohan, go to the kitchen and get whatever you want, do whatever you want, just be your own home, I want to think about something." ”

Without waiting for Ruohan to speak, I lit a cigarette and walked into the study.

"What the hell did I think, why did I have a feeling of unlocking so many secrets? What the hell is going on! ”

I asked myself repeatedly in my heart! What exactly happened to me when I was listening to the lecture suddenly made me think about something.

"Hey! Stupid ......"

"Why did you get into my study......

I don't like people coming into my study, it's my private space! It's a little world for me! Although Wakahan is a good friend of mine! But there was still displeasure on his face.

Ruohan can also see that I am a little unhappy! Ruohan muttered, "Your water dispenser is out of water......

"Oh...... Okay, I'll help you change the water......"

With that, I snuffed out the cigarette in my hand and put it in the ashtray......

"You idiot, your sleeves are stained from smoking, wipe your ...... quickly"

As he spoke, Ruohan rolled up my sleeve with his right hand......

This simple act suddenly lit up my mind and reminded me of how I felt when I was listening to the lecture......

I grabbed Ruohan's right hand and said, "I understand...... I know what's going on......"

I hurriedly shouted, "You can take it with you at my house!" I've got something to get out! Thank you. You helped me remember something very important. ”

After speaking, he ran out of the house without replying.

Ruohan looked at my back inexplicably, and was about to say something, but seeing that I had no shadow, Ruohan had no choice but to take it home obediently.

Ruohan didn't mention it for the time being, so I left the door of the house and immediately took a taxi. The driver asked me where to go. I replied, "Interpol Brigade."

Looking at Yu Xiaodie's photo in the car, I felt a very comfortable feeling in my heart, the whole case was like a ball of twine, which made me find the thread.

"Yu Xiaodie, bless me to find out the truth and give you a fair ......"

The driver of the taxi was a veteran, and it didn't take long to pull me to the criminal police brigade......

"Uncle Wu, I'm in a bit of a hurry to find you, I want to check a person's information, can you see it?"

I gasped for breath and ran into Uncle Wu's office without even knocking on the door. At this time, Uncle Wu chatted with several colleagues, probably for the purpose of investigating Yu Xiaodie's case.

When Uncle Wu saw me, he ran in without a serious attitude, and Uncle Wu said, "Xiao Yang! Let's go get busy first! I'll call you again when there's something."

He turned to me and said, "Forward!" What's so frightening...... Take your time and don't rush".

I hurriedly said, "Uncle Wu, Yu Xiaodie's matter!" I found an important clue, please help me anyway......"

Seeing that I was nervous, Uncle Wu smiled and said, "Okay! Sit down and talk slowly, what the hell is going on? ”

Uncle Wu is very good to me, and patiently teaches me everything and takes care of me! That's why I'm interested in the relationship.

I told Uncle Wu all the 217 files in Yu Xiaodie's photos and the things I found in the archives, especially the inspiration in the afternoon, which made me vaguely feel the direction of solving the case.

After telling everything before and after, Uncle Wu said happily, "Good boy. Uncle Wu knows that you are a very smart boy, and this is all for you to find out...... It's amazing."

"Uncle Wu, if you want to praise me, praise me in the future! You hurry up and help me look up what I want to know. I also thought about the case for a long time before I came, if nothing else, we can catch the real murderer tomorrow. ”

"Good...... Walk...... Let's take a look at who this Professor Cheng is......"
