The Department of Biological Theory is a biological research base, where a young girl dressed in white is busy with biological research.

In the silent corridor, there was the sound of slight footsteps. Another man dressed in white walked into the Department of Biological Theory, and this person was the master of this department. Professor Cheng......

As soon as Professor Cheng entered the room, he sighed, "I'm really tired today."

"Yes! Professor, I heard that you have a wonderful speech today! It's the perfect course in biology, so many students say. ”

Professor Cheng just smiled slightly, didn't say anything, just looked at his speech silently, as if he knew what was going to happen.

The department had begun to quiet down, and both of them were busy with their work, and neither of them was chatting with anyone anymore.

After about ten minutes or so, a word suddenly broke the silence of the biological theory laboratory.

"Professor Cheng, it's been a long time, and the two of you are in Xiaodie, let me say hello to you."

Yu Xiaodie's three words, the professor's face twitched when he heard it, and he slowly turned his head in the direction of speaking.

The professor's face was very hideous, as if he had heard a call from hell, and his expression was very surprised.

It was none other than me who spoke.

I shouted again, "Professor Cheng, I finally found you, what a lot of effort!" ”

The professor looked at me in surprise and said, "Who are you?" This is the biology lab, what are you doing here? ”

"Professor, I'm a student at school. I've listened to your classes. How? Forgot me? ”

When the professor heard that I was a student, he immediately breathed a sigh of relief, and his face was not as hideous as it was just now.

The professor said calmly, "Since you are a student, you should go back to your classroom right away instead of coming here." ”

I smiled, "Haha...... Haha"

"Professor, don't you be in such a hurry? I'm here to tell you a story, where do we start? ”

"What the hell are you going to do?"

The professor's face turned unnaturally again, as if he wanted to kick me out.

This story starts seven years ago, a girl from Yu Xiaodie has just been admitted to college and is studying hard, but unfortunately, Yu Xiaodie fell in love with someone she shouldn't love. Professor, do you know who this person is? ”

"You...... Who are you to? What the hell are you going to do? ”

Professor Cheng's tone and voice became louder and louder, as if he was going to eat me, if it weren't for his identity, I guess Professor Cheng would definitely make up for me and beat me" Yu Xiaodie is a naïve girl, thinking that person will love him for a lifetime, but the result is not that Yu Xiaodie could have imagined that the man Yu Xiaodie loved killed Yu Xiaodie for his own career and the so-called morality in society. Am I right? Professor Cheng? ”

"You talk nonsense, you don't know anything. Don't talk nonsense here. ”

Professor Cheng was now angry, and immediately walked up to my side, grabbed my arm with his right hand, and forcibly pushed me out of the department. Professor Cheng's strength is very strong, as if he wants to press a cow to death, and he can't feel the weakness of a cultured person at all.

I didn't rest on my laurels, my right hand grabbed his right hand and froze in place.

The scene was frozen there all of a sudden, neither of us would budge, but fortunately I was young and had some strength. And Professor Cheng pushed me a few times, but he didn't push me, and sweat flowed from his face.

He shouted, "You student is so rampant, hurry up!" Otherwise, I will go to your director of discipline, and I will definitely make you unable to eat and walk around. ”

In fact, everything was expected by me, and I scolded in my heart: "Why haven't the people outside come in yet?" ”

"Professor Cheng, why don't you let you go forward and say it."

When a person walked in through the door, I felt a lot more at ease.

"Uncle Wu, why did you just come in, I was almost sent out."

I asked Uncle Wu angrily, and made a dissatisfied expression on the surface.

"Alright, alright, move forward......"

Uncle Wu turned to Professor Cheng and said, "Professor Cheng! Let's listen to the words first! All right? ”

Professor Cheng saw that Uncle Wu was wearing a police uniform, and the shoulders of the police uniform were deeply typed with the words "criminal police". Professor Cheng also understood what was going on. Professor Cheng's death suddenly became hideous, and he probably already knew that something was about to happen.

"Professor Cheng, do you know why I found you?"

I saw that everything was a foregone conclusion, and I said confidently.

"In fact, I saw a clue in the photo of Yu Xiaodie, who died recently, and then I followed the clue to find the file seven years ago, and it turned out that there was a Yu Xiaodie seven years ago. After investigation, it turned out that Yu Xiaodie seven years ago was called Yu Xiaodie, and now she died because Xiaodie was called Yu Xiaorong. ”

I looked at Professor Cheng as I spoke, and Professor Cheng found that I was looking at him, and Professor Cheng argued forcefully: "What are these two people's names, and what does it have to do with me." ”

"Huh! Professor Cheng, don't worry. This matter starts seven years ago, as I said just now, seven years ago, a girl named Yu Xiaodie had just been admitted to college, and she knew a man who had just become a teacher. It didn't take long for the two to fall in love. But they know that teacher-student love is not allowed by the world and society. But unlucky, Yu Xiaodie had that man's child. In desperation, the man killed Yu Xiaodie and committed suicide. ”

When I said the word killing, Professor Cheng's whole body trembled, and his facial expression was already understood by everyone in the classroom.

I didn't pay much attention to Professor Cheng's expression when I saw it, and I said, "It's over, after Yu Xiaodie's death, her sister didn't believe that her sister committed suicide. Seven years later, in order to investigate the cause of her sister's death, Yu Xiaorong was also admitted to our university. Especially when she met the man who killed her sister, Yu Xiaorong did everything possible to get close to that man, and even had a relationship with that man. Later, Yu Xiaorong also had that man's child. Things are another reincarnation, and that man also killed Yu Xiaorong, making it a suicide illusion. But the man was wrong in several ways. ”

Uncle Wu asked, "What are the points?" ”

"First, when Yu Xiaorong hanged herself, there was a long distance between the chair and her body, which was the man's biggest mistake. It's strange to ask how a suicidal person could allow himself to levitate in mid-air. Second, Yu Xiaorong planned to investigate the cause of Yu Xiaodie's death, so it can be seen how stupid the murderer is. ”

"You've done a good job of analyzing it, go on."

"In fact, looking for someone is really looking for a needle in a haystack. But thanks to the restoration of this world's skynet, I was forced by Lao Dong to listen to Professor Cheng's course, which made me discover some things. Let me solve all the doubts at once. ”

"What the hell is going on? Go ahead and don't sell it. ”

"It's Uncle Wu. Originally, I was not interested in biology, I almost fell asleep listening to Professor Cheng's lectures, when I was confused, I found that Professor Cheng had a scar on his right hand, at first I didn't care, when Ruohan tidied up my right sleeve, I found a big secret, in the 217 file I saw a photo, it was a man holding a photo of Yu Xiaodie seven years ago, and the man in the photo also happened to have an identical scar on his right hand, which reminded me of Professor Cheng's identity. ”

I made up my mind and said, "Later, I ran to Uncle Wu and asked Uncle Wu to investigate Professor Cheng's personal information for me, and finally all the mysteries were solved." You killed Yu Xiaodie seven years ago, and you killed Yu Xiaodie seven years later, what else do you have to quibble. ”

As I spoke, I took out the document bag of Uncle Wu's investigation from my bag and threw it at Professor Cheng, who was shocked by my sudden move, and with a flash of light, the documents in the entire document bag were scattered all over the place, and the ironclad evidence made him speechless. Professor Cheng is now standing there silently like a lost dog.

Uncle Wu said, "Professor Cheng, what else do you have to say?" Come with us. ”

Professor Cheng smiled: "I didn't kill anyone, yes, I was the man who fell in love with Yu Xiaodie seven years ago, but I didn't kill Xiaodie, because we really love each other." I still remember that seven years ago, I just graduated and came to Changke University as a professor and lecturer, at that time I was just an ordinary lecturer and didn't earn much money, but I didn't expect my student Yu Xiaodie to fall in love with me, and I slowly fell in love with Yu Xiaodie. ”

Professor Cheng cried as he spoke, looking at Professor Cheng's sad eyes, I still felt that Professor Cheng also had true feelings.

"But who knew that my father knew about me and Yu Xiaodie, my father was an old-fashioned person, and my father did not allow me to fall in love with my students, which would damage my future. The unanimous opposition of her parents often puts pressure on Xiaodie. But who would have thought that Xiaodie had my flesh and blood, and just when I was about to give up everything to marry Xiaodie, Xiaodie was persuaded by my father's words and finally committed suicide. I love Xiaodie so much, how can I kill Xiaodie! I didn't kill Xiaodie. ”

I smiled and said, "Professor Cheng, what you said is indeed touching, but you can say whatever you said seven years ago, if you hadn't killed Yu Xiaodie, why wouldn't you dare to disclose your relationship with Yu Xiaodie." Yu Xiaodie committed suicide, why did Yu Xiaodie's sister Yu Xiaorong seek revenge on you. It seems that your technique of lying is not very clever. ”

Professor Cheng sighed and said lamentingly: "Five years ago, my father passed away, but I missed Xiaodie at all, this year I found out that a girl who missed Xiaodie very much came to Changke University, I thought that God gave Xiaodie back to me, let us continue to live." Who knew later that I knew that Xiao Rong was taking revenge on me for Xiaodie, but I didn't kill Xiao Rong either, because I had already thought of being ruined, and I didn't care anymore. ”

"Hehe, Professor Cheng, you are so great. If you didn't care about fame and fortune, I wouldn't have had such a hard time looking for you. ”

There was a lot of sarcasm in my words, and Uncle Wu seemed to realize that the time was ripe, and Uncle Wu said, "Okay, Professor Cheng, you can come with us!" Come on, bring Professor Cheng back. ”

The criminal policemen outside the door heard Uncle Wu's words, and walked in three criminal policemen at once, one of whom also took out handcuffs and planned to lock up Professor Cheng.

Professor Cheng saw that a criminal police officer was coming to arrest him, so he hurriedly ran to the window, and said as he ran: "I didn't kill Xiaodie and Xiao Rong, don't come here!" I'll jump from here again! ”

As he spoke, Professor Cheng forcefully opened the window of the biology department, jumped onto the windowsill, and half of his body was already leaking outside.

Professor Cheng's move surprised everyone.

I shouted: "Professor Cheng, the evidence is conclusive, what are you doing, don't you feel that you are very **?" ”

Professor Cheng also said: "Young man, you didn't investigate clearly, I didn't kill Xiaodie and Xiaorong at all, it's not me at all, why do you have to sprinkle salt on my wounds." I have nothing to say at this point, and now you won't believe anything I say, but God can testify for me, I didn't kill Xiaodie seven years ago, and I didn't kill Xiaorong seven years later. Xiaodie, I'll go down to you right now. ”

As soon as the words fell, Professor Cheng turned around and wanted to jump out of the window, although there were more of us, but we didn't find out that Professor Cheng had jumped off the building in time.

This moment was the first time I really felt like a person jumping off a building, Professor Cheng just jumped down, my head also stuck out of the window, I saw Professor Cheng fall in the air, and his mouth also shouted loudly.

"I didn't...... Kill Xiaodie......"

I felt how loud the voice was, and I felt that it was a person shouting from the heart, and there was no falsehood at all.

There was a loud bang ......, and the calm school was suddenly not quiet. Professor Cheng was surrounded by many students from Changke University. The students were whispering there, asking what the hell was going on......

And I'm ...... The feeling in my heart is indescribable
