Xiao Song took Xu Xin into Li Bing's room, and Xiao Song, who was already traumatized by Professor Zhao Shengli's death, unexpectedly received a call from Xu Xin.

After listening to Xu Xin's narration, Xiao Song also hesitated for a while, and his official identity did not allow him to believe Xu Xin's words. If it is spread out, a dignified deputy captain of the criminal police resorts to superstition because he can't solve the case, which will not only make people laugh, but I am afraid that his position as the deputy captain of the criminal police team will have to come down before he is hot.

Therefore, Xiao Song asked Xu Xin to keep quiet, and he quietly took Xu Xin to Li Bing.

Xu Xin recounted the nightmares he had in the past two days, in which he saw his godfather, Professor Zhao Shengli, constantly dragging that chilling tone and saying that he had died unjustly. But Xu Xin couldn't see Professor Zhao's face clearly in his dream, but a piece of paper full of red crosses and a rope kept appearing.

After listening to Xu Xin's speech, Xiao Song looked at Li Bing with expectant eyes, hoping to get a reasonable explanation.

Li Bing thought about it for a long time, but he didn't understand what Xu Xin's dream meant. He suddenly thought that since Xu Xin was Professor Zhao's righteous son, and Professor Zhao had to support his dream, why not invite Zhang Yuanshan to open the altar to practice psychic skills?

Zhang Yuanshan smiled, and according to Li Bing's request, he opened the altar. Sure enough, the result of the psychic was the same as Xu Xin's dream, and Professor Zhao kept shouting that he had died unjustly. And the rope and the crossed-out paper really appeared, and nothing else could be seen.

A few people pondered what this result meant, and Xiao Song thought for a while and said, "Li Bing, I only know one thing, judging from what you encountered before, I also secretly have to admit that there are indeed ghosts." Therefore, since Professor Zhao will entrust his dream to Xu Xin, and the result of Brother Zhang's psychic practice just now is also the same, it shows that Professor Zhao did not commit suicide, but killed him, so he will not be gone, and he hopes to entrust his dream to avenge his grievances. ”

Li Bing nodded in affirmation of Xiao Song's thoughts, and he said slowly: "It seems that the mystery is on that rope and that piece of paper with a red cross." The rope is understandable, and this is the factor that directly led to Professor Zhao's death by hanging, which may imply that someone strangled the rope around his neck. But what does the red-crossed piece of paper imply? ”

Zhao Wan'er tilted her head and thought for a while, and suddenly burst out: "I had a lot of red cross paper, I had a lot of red cross papers, I did the wrong questions, and the teacher was all red cross crosses." ”

Li Bing's eyes lit up, he walked around excitedly, and cheered for a while: "I understand, the professor's unjust spirit is implying that the person who killed him is a student, and that student has bad grades." ”

Xiao Song told Li Bing, and he was also inexplicably excited, and he asked Xu Xin anxiously: "Do you know which of the professor's students have bad grades?" ”

Xu Xin shook his head in embarrassment: "There are a lot of students brought by the professor, and there must be a lot of bad grades." ”

Xiao Song's eyes pressed at Xu Xin: "Xu Xin, think about it again, which of your classmates has bad grades, and he usually complains about the professor." ”

Xu Xin thought for a while, and said helplessly: "There are a lot, but unfortunately I am not very familiar with it, and the only one who is familiar is called Wang Wei." The sketch that the professor taught him was indeed a failure, but he didn't show any special hatred for the professor. ”

"Wang Wei?" , Xiao Song asked with interest: "Tell me about his specific situation." ”

Xu Xin said, "Officer Song, are you starting to suspect him?" Probably not. Wang Wei has never had personal contact with the professor, and he rarely speaks, but he is a well-known loyal person in our class. ”

Xiao Song interrupted Xu Xin's words: "I don't need you to draw conclusions now, just tell me about Wang Wei's situation." ”

Xu Xin hummed and said: "Wang Wei is from Guizhou, in the same class as me, he is usually very introverted and has almost no friends. Wang Wei also lived in the same dormitory with me, and the other three classmates all looked down on Wang Wei, so they ignored him. ”

Xiao Song asked rhetorically: "Xu Xin, what about you?" How is the relationship with Wang Wei? ”

Xu Xin hesitated for a moment and said: "At first, I didn't have anything to say, but then the relationship got better, and I became his only roommate who was willing to talk." ”

"Why?" Xiao Song asked reluctantly.

Xu Xin said with some embarrassment: "It's not because of Professor Zhao's sketch class, Wang Wei took the make-up exam twice in a row, and all of them failed." In the second half of last year, Professor Zhao, who had always admired me, felt lonely after losing his wife and wanted to recognize me as his son. To have such a respected professor as a godfather, of course, I can't ask for it. ”

Since then, Wang Wei has looked at me differently, and many times he seemed to have something to say to me, but he stopped talking. Once, while the other roommates were away, he dragged a crumpled cloth bag from under the bed and took out their Guizhou specialties, tribute noodles and bamboo sunflowers. He was embarrassed to stuff me, saying that his family was poor and that he had nothing to give me, only souvenirs brought from his hometown. ”

"I was so surprised that I didn't know what he wanted to do. He blushed and insisted that I take it. I saw that a person like him, who is usually very wooden, actually took the initiative to show favor to me, and I didn't want to embarrass him with kindness, so I accepted it. In this way, we became friends, he often brought me souvenirs, and I understood what he meant, and asked me to give him an accommodation in front of Professor Zhao, let him go, and let him sketch to pass the test, without affecting graduation. ”

Xiao Song frowned and said, "Did you help him?" ”

Xu Xin hurriedly said: "I helped him, but I didn't expect Professor Zhao to be very rigorous in academics, and he didn't let go, telling me that he would not give up his principles, and only if Wang Wei met his requirements, he would let him get credits." I told Wang Wei the news, and he was very devastated and depressed than before. ”

Xiao Song pondered for a moment and said, "In this way, this king is only quite suspicious. By the way, did he negotiate with Professor Zhao in private? ”

Xu Xin shook his head and said affirmatively: "No." Wang Wei is relatively slow to respond, he is wooden, and his Mandarin is not very standard, and few of our classmates call him by his name, and they all call him 'Little Guizhou'. Professor Zhao also has no good impression of Wang Wei, and has never been in contact with Wang Wei alone. ”

Xiao Song asked, "On the night of Professor Zhao's accident on Saturday, what abnormal behavior did Wang Wei have?" ”

Xu Xin thought for a while and said, "No, but he did ask me for one thing that day, and asked me to help him intercede with Professor Zhao again." We usually talk to a few classmates in the dormitory, and I mentioned that Professor Zhao is from Northeast China, and he likes to eat chicken stewed mushrooms the most, and he must have this dish almost every day, and he also pays attention to the way of health. Perhaps Wang Wei begged Professor Zhao to silently remember my words. That day, he quietly handed me a packet of mushrooms and a packet of sesame seeds for me to pass on to Professor Zhao. ”

Hearing this, Li Bing sighed: "It seems that there is indeed a problem with this Wang Wei, everyone has seen a lot on TV, often people who have committed criminal cases, after being arrested, the neighbors on the left and right will not believe that such an honest person would kill someone." Maybe Wang Wei belongs to the kind of people who are psychologically distorted due to loneliness, and finally have evil thoughts. ”

Xu Xin hurriedly argued: "No, I don't believe that Wang Wei is this kind of person." I sympathize with him, but his family is not good and he has no friends. I also gave him a little idea for this, and I didn't tell Professor Zhao that the two bags of things he asked me to hand over to Professor Zhao were given by Wang Wei. I want to let the professor eat it first, and when he owes the favor, then tell the professor who sent it, and let him open his eyes and close his eyes to let Wang Wei pass. ”

Xiao Song suddenly said: "Xu Xin, you did rule out suspicion, that is because Professor Zhao died at two or three o'clock in the morning, and you returned to the school dormitory at eight o'clock." You and the other roommates played all night, so they can all testify for you. I was negligent at the time, you played cards with four people, and you had five people in your dormitory. I think, that unsociable Wang Wei didn't have a card with you, right? Where was he then? ”

Xu Xin also paused, thought for a while and said, "Impossible." Although Wang Wei was not social, he did not leave school that day. After dinner, he spent his time painting in his bedroom. Later, when I returned to the dormitory at eight o'clock, the four of us started playing cards, and he naturally didn't participate, not to mention that the other three didn't want to play with him. Maybe we were too noisy, and he didn't dare to talk about us, so he went to the corridor alone to read. It wasn't until we were in the wee hours of the morning that he probably couldn't take it anymore and went back to his dorm room and climbed into his bed. ”

The sensitivity of his profession made Xiao Song smell a hint of excitement that made him excited, his eyes were firmly on Xu Xin, and he looked at Xu Xin in a panic, and unconsciously lowered his head.

Xiao Song asked, "Xu Xin, are you sure that Wang Wei went back to sleep in the bedroom after midnight?" Before that, are you sure he never left the hallway? ”
