[Thank you for the monthly pass of Piggy and Doll Demon Girl!] You are my little apple~]

When Fang Yuan heard this, he also wanted to laugh a little, in front of Yang Fan and Xu Yongheng, he had to endure it hard, because he and Dai Xu were masters and apprentices, partners, and roommates, as Dai Xu's good buddy, Zhong Han was naturally a little more enthusiastic and close to himself than others, plus Zhong Han's kiss and girlfriend Gu Xiaofan was notoriously good-tempered, and she usually got along with Fang Yuan extremely well, so about Zhong Han's personality that combines narcissism, cleanliness and obsessive-compulsive disorder, Fang Yuan had heard of it from time to time.

Ke Xiaowen didn't know if the quilt on the bed was because he was in a hurry, so he didn't have time to fold it, whether it was the workbook next to the pillow or the personal belongings in the iron locker, they were all neatly packed, even in the slightly cramped and simple small bedroom in his house, whether this degree was obsessive-compulsive disorder, Fang Yuan couldn't say it well, but such a decent person, taking Zhong Han's habits on weekdays as a reference, he could still find a little commonality, Dai Xu only mentioned it so simply and casually, and Fang Yuan immediately realized that a person who placed items very regularly and neatly sandwiched an ordinary-looking soft-sided copy between other larger and thicker workbooks, naturally to hide, rather than place them randomly.

After getting the wooden man and the soft face copy, basically there was not much else worth noting, Dai Xu and Fang Yuan thanked Xu Yongheng and Yang Fan, and planned to leave, Xu Yongheng was still doing the exercises on his own. Hearing that they were leaving, he only raised his head slightly and looked at the two of them. nodded, very arrogant, but Yang Fan was very enthusiastic, and he had to send them downstairs, saying that he didn't want to do anything in his life, and it was estimated that he had no other opportunities to contact the police except for changing his ID card, and this time it had nothing to do with him. You can also deal with the police, I think it's cool, and you have to take the opportunity.

This is what Dai Xu said to him. Just smiled, nodded, thanked him, and accepted it.

Yang Fan followed Dai Xu and Fang Yuan downstairs all the way. From time to time, I also greet other students who come upstairs. casually teased a few words, which looked like a bag with a relatively large social circle.

When he arrived downstairs, Yang Fan didn't stop, but followed Dai Xu and Fang Yuan forward, and after walking out for a distance, Dai Xu stopped first, turned around, and said to Yang Fan with a smile: "Do you have anything to say to us?" If you want to say it, you can say it. After walking so far, it is estimated that no one can hear it. ”

Yang Fan was stunned for a moment. Scratching the back of his head, he asked a little annoyed, "Is it so obvious?" ”

"It's not obvious, the main thing is that I'm smarter." Dai Xu responded jokingly.

Yang Fan burst out laughing and gave Dai Xu a thumbs up: "Big brother, you're so funny!" You're killing two birds with one stone! Praise me again, and praise yourself again! If that is the case, then you are really smart enough! ”

"If you have anything, just say it, it's very cold at night now, you're in your third year of high school, don't catch a cold." Dai Xu motioned for Yang Fan to go straight to the point, his words were not false, now in this season, the night is really starting to get cold.

Yang Fan hurriedly nodded and said, "I actually just want to ask a question first, if it's deep and shallow, don't be like me." Ke Xiaowen: Did something happen to him? ”

"Why do you ask?" Fang Yuan frowned and asked Yang Fan rhetorically.

Yang Fan shrugged his shoulders and pointed at Fang Yuan: "I saw your ID, you are a criminal policeman, I have read it in novels and TV, you people don't care about small things, you are in charge of killing people and overselling goods!" ”

"That's not necessarily, the criminal police actually have a lot of specific and different divisions of labor." Dai Xu replied more ambiguously, and then said, "But in fact, according to your concept, Ke Xiaowen can be regarded as having something wrong, after all, a senior in high school, he didn't go home, he didn't come to school, he didn't even say hello, and he died at home and school, this must be considered something, right?" ”

"Oh, if you say that, it makes sense." Yang Fan pouted and nodded, "I thought something big had happened to Ke Xiaowen, so I deliberately came out to inquire." ”

"Do you think something big should happen to him, or is it easy to do something?" Dai Xu asked.

As soon as Yang Fan heard this, his two eyes suddenly widened, and he waved his hand again and again: "Oh, brother, you can't joke with me like this, I'm still a child, timid!" What do I think something should happen to him, as if I'm looking forward to what happened to Ke Xiaowen! No, I usually get along with him very well, I can't see it, basically belongs to the all-round development of morality, intelligence, physical fitness, art and labor, except for poor academic performance, all other aspects are still very good, Ke Xiaowen is a top student, and I am not a world like this, and he is a key class, is the kind of person who usually studies in the classroom until ten o'clock, washes and washes when he goes back to the dormitory, and continues to read with a flashlight on the bed! What about me? I usually go back to the dormitory at eight o'clock, half of the homework is written, half of the homework is copied, and when I go back to the dormitory, I can still talk to others, and secretly flip through two martial arts novels or something, oh, by the way, Ke Xiaowen also lent me a volume to copy, what do I have to get along with others, the well water does not violate the river water. ”

"And what else do you want to offer us?" After all, Fang Yuan was relatively young, and he had only left high school life for a few years, in her concept, a naughty student like Yang Fan, and a student like Ke Xiaowen who studied honestly and hard, really rarely had conflicts, let alone the extent of being a killer, so she still believed in Yang Fan's confession.

Yang Fan touched his head, and glanced in the direction of the dormitory building with a weak heart: "I said it, can you keep it secret for me?" I read that it says that we all have to protect the witnesses, don't we? ”

"Well, keep it secret, you name it." Fang Yuan nodded, and hurriedly came down, lest Yang Fan be too long-winded.

Yang Fan breathed a sigh of relief: "Then I can say it." If, I mean, if something happens to Ke Xiaowen. You should pay attention to the kid just now, the one who went back to the dormitory with me, Xu Yongheng. ”

"He? Is his relationship with Ke Xiaowen strained? Fang Yuan was stunned for a moment, the boy's lukewarm performance just now was a little impressed, but there was no way to imagine that such a taciturn boy would have anything to do with a notoriously honest boy like Ke Xiaowen.

"Of course their relationship is strained! You don't see it, do you? Yang Fan raised his eyebrows, for something that the police did not find. I felt very proud that I had touched this kind of thing clearly, "You don't know, right?" Xu Yongheng is a person who has a deep mind, and he is quite yin, he is a top student in the ordinary class. Since I was a freshman in high school, I have always wanted to be admitted to the mobile key class. The result has always been a little bit closer, and he just couldn't get in, and when Ke Xiaowen waited, he was a student in the mobile key class since his first year of high school, and he had never been transferred out for several years, just this matter, Xu Yongheng has been sour for a long time. Behind the scenes, there are some weird words of yin and yang, and some time ago, wasn't it rumored that the flow method of the mobile key class was going to be reformed. He also went out of his way to inquire with Ke Xiaowen, saying that if he really didn't advance, he would retreat, so Ke Xiaowen's ranking in the whole grade had not fluctuated, should he be retired, and he was a little unhappy with Ke Xiaowen at that time, but he was not happy. ”

"Ke Xiaowen quarreled with him?" Dai Xu asked tentatively.

Yang Fan waved his hand: "How can it!" If Ke Xiaowen can quarrel with others, he will not be Ke Xiaowen! He just had a white face, so he avoided Xu Yongheng and didn't want to listen to him to inquire about those things, saying that he didn't know, Xu Yongheng always seemed to be unable to see it, chasing after people's butts and saying those useless nonsense, and finally annoyed Ke Xiaowen, ignored him, ran to the toilet to read a book with a book, and hid until the lights went out before coming back. Oh yes, Xu Yongheng also likes to compare with Ke Xiaowen, what time does Ke Xiaowen learn, he must sleep later than Ke Xiaowen, I think he is the kind of person who has been secretly fighting with Ke Xiaowen, but unfortunately, he has never gone over. ”

"That Xu Yongheng is quite thoughtful." Dai Xu said as if he suddenly realized.

Yang Fan nodded vigorously: "No, this kid is silent all day long, wilting bad!" ”

"Then I see that you got along quite well with him just now." Fang Yuan said casually.

Yang Fan's face was slightly red, hehe laughed twice, and said: "It's a play on the spot, there are only two people who study top-notch children in our dormitory, Ke Xiaowen is a mobile key class, sometimes the homework and exercises are not the same as ours, I'm a little lazy, sometimes, I don't want to do the paper, I have to borrow it and copy it, if I find a special one without a score, I copy it wrong, and the teacher has to ask me where I am wrong, where I know where I am wrong, and the question is written by the grandson who did it wrong!" So be it...... Hey, hey, I can't help it. ”

Dai Xu nodded and expressed understanding, Yang Fan felt that his words seemed to be enough, and the time to come out was not short, so he said hello to them and trotted back to the dormitory building.

"Do you believe what he says?" Fang Yuan asked Dai Xu, and by the way, he said how he felt, "I think this kid is a little flamboyant, as if he is not particularly reliable." ”

"People with slippery heads may not be credible, mainly depending on his position and role, if there is no harm to himself, he will not deliberately lie, because lying is not good for himself, and it is easy to get into trouble if he doesn't do it well." Dai Xu said to Fang Yuan, the meaning of his words seemed to be more inclined to believe Yang Fan than Fang Yuan, "Don't talk about killing someone, even if you kill a chicken, maybe everyone has that courage, right?" It takes impulsiveness or a deep hatred. Judging from Ke Xiaowen's case this time, the possibility of impulsiveness can be directly ruled out, then only hatred remains, if there may still be some sense of competition between Xu Yongheng and Ke Xiaowen, is it enough to constitute a motive for murder, this is hard to say, but in comparison, it must be more adequate than Yang Fan's motive. Another thing, you also think about it, Forensic Doctor Liu told us before, what was the cause of Ke Xiaowen's death? ”

"It is suspected that someone injected hydrogen peroxide into the veins with a syringe, producing a large number of bubbles...... Fang Yuan instinctively recalled, and only halfway through his words, he stopped, and the expression on his face was also suddenly realized, "This person either has a certain amount of medical knowledge, or he is smart and has mastered this knowledge, so he knows that hydrogen peroxide injection into the deceased's body will form a large number of bubbles, making the heart stop beating!" From this point of view, if Yang Fan is really a student with poor academic performance and messing around, then it may be difficult for him to think of killing people in this way. Lying about other things may not be easy to verify, but as a student, if you lie, it is too easy to debunk. ”

"Now you understand, right?" Dai Xu nodded, smiled and looked at Fang Yuan, who suddenly realized, "Although Xu Yongheng may not really be suspicious, but at least Yang Fan should really want to provide us with some information, as for whether he and Xu Yongheng are acting on the spot, or whether his interactions with everyone are acting on the spot, then it has nothing to do with us, and there is no need to waste too much energy on Yang Fan's character." ”

"That's right, we also found Ke Xiaowen's diary, I don't know if there can be anything valuable on it." Fang Yuan patted his carry-on backpack, and the soft-faced copy and wooden man were stored inside, "Ke Xiaowen's locker is locked, but when I went to look at it just now, his cabinet was not locked, and I also looked at it, it should not have been pryed open, but he forgot to lock it from the beginning, there was a wallet in his locker, but it was empty, there was nothing, so I didn't deliberately pick it up to show you." I think from these circumstances, Ke Xiaowen may be a little uneasy on the day of the accident, as a boarding student, it is impossible for him to have a dime left in his wallet, unless he brought all the money with him, and was taken away by the murderer after the accident, so when we found the clothes, there was nothing in the pocket. ”

"If this is really the case, we know that Ke Xiaowen hurriedly went out of the school gate after evening self-study that night and ran home, then it seems that he was ready to leave next night during the day, is it that the murderer laid a trap for him early and waited for him to jump in, this has to be confirmed again." Dai Xu looked at his watch, "Let's go, we're almost forty minutes late, and we have to eat this meal after all." (To be continued......)
