Ouyang Qian said: "When you say this, I think about it, when we checked the room that day, I did find a book of unsolved math mysteries, philosophy and the like, but the printing was complete, I didn't care much about it at the time, and now I think about it, it is really unreasonable." ”

I thought to myself, "How can a farmer, an idle man, teach himself such advanced things as mathematics and politics?" What the hell is a code in that book or what? ”

Bidding farewell to this female neighbor, I hurried back to Wang Yun's house, walked into Li Zhenbo's room, and did see two large books on the table, I looked at the first page: "Goldbach's Conjecture", which was a full fifty pages talking about why this problem existed, I briefly looked at it a few times, it was really boring.

I asked Ouyang Qian, "What do you think?" ”

Ouyang Qian said: "As a farmer, reading these books is a bit too abnormal. ”

The stacks of these books are almost as tall as my legs, which is a bit too high for Li Zhenbo.

Li Zhenbo is dead, and now there is no way to ask the person concerned, I can only ask Wang Yun's mother and daughter who live with him.

I asked Wang Yun, "Do you know that your uncle has always liked to read these advanced mathematics and philosophy books?" ”

Wang Yun said: "I know he has been reading this, but I guess he didn't understand it, so he ignored it." ”

I asked, "Is Li Zhenbo educated?" ”

Wang Yun thought for a while and said: "My uncle and my mother grew up in the same family, because my mother is the eldest daughter, and she is better at studying and more sensible, I remember my mother said that when she was at home, she gave my mother the only opportunity to study, but she did not study hard, she was not admitted to university, and now she is the same as my uncle, a farmer, for this incident at that time, my mother has always been very guilty." ”

I called Wang Huizhen and asked, "Your daughter said that when you and your brother were studying, the family gave you the only opportunity to study, is there such a thing?" ”

Wang Huizhen said: "Yes, the conditions at home were more difficult at that time, and there was indeed only one person to study, when I was in elementary school, my grades were relatively good, but after I went to junior high school, things became difficult, I couldn't learn, and I also lent the book to my younger brother, that is, Li Zhenbo, and then he taught me after self-study, but he still didn't go to school." ”

At this time, I suddenly discovered the surname problem of Wang Huizhen and Li Zhenbo, so I asked: "Why is your surname Wang and your brother's surname Li?" ”

Wang Huizhen said: "When I was very young, my mother died, and my father found a woman the next year, and then two years later gave birth to a younger brother, he is Li Zhenbo. ”

I thought to myself, "No wonder the relationship between the two is so bad." ”

I asked, "Did your family say anything about you not being admitted to college?" ”

Wang Huizhen sighed and said: "Alas, it's uncomfortable to say, my family is so poor, I didn't grasp the opportunity to study, but Li Zhenbo is really smart, he didn't like to deal with people since he was a child, his family thought he was stupid, I was also young at the time, I don't know how big the family sacrificed, I still regret it when I think about it now." My family didn't say anything about me not being admitted to college, just as if nothing had happened, probably because they spoiled me too much, and this is why they hurt me. ”

I asked, "Was Li Zhenbo's childhood miserable?" ”

Wang Huizhen said: "Sort of, my father's woman has no status in the family, my father still spoils me very much, everything is towards me, Li Zhenbo almost didn't care about it." ”

I asked, "Then he didn't resist much?" The family is very bad to him? ”

Wang Huizhen said: "Definitely not, at home, when I was young, I tried to help him, except for blaming me for learning this, I am still very eager for him, after all, he is my younger brother." ”

I remembered that the reason why Li Zhenbo was dug up was that the passbook was still on his body, and this kind of thing that could be redone disturbed the deceased, and it must not be good for Li Zhenbo at all.

I asked, "Li Zhenbo is so sloppy, you live together, you haven't said it?" ”

Wang Huizhen said: "No, after all, they are all adults, how can bad habits be changed?" I didn't care about him, anyway, I washed my clothes by myself, and I endured the dirt by myself, why should I care about him? ”

I still have some doubts in my heart, it is about poison, although arsenic can be used as medicine, but it is not easy to get a dose that can poison people.

At this time, I was more curious about how to arrange the room where Li Zhenbo lived, so I asked Wang Huizhen: "As soon as Li Zhenbo dies, does this house belong to you?" ”

Wang Huizhen said: "Yes, after all, my father and my stepmother are dead, and I am the only one left in the family, and the house must be mine." ”

I thought of another possibility: "Could it be that Wang Huizhen brutally killed Li Zhenbo because of this house?" ”

This possibility still exists, although it is very unlikely, but it is still necessary to rule it out.

This is an unlikely reason to kill, but it has to be ruled out, judging from the expressions of Wang Huizhen and Wang Yun, it can be concluded that the relationship with Li Zhenbo is not good at all, is there really such a person?

I carefully used a fingerprint detector to record the fingerprints on the electric heater, and came to the conclusion that it was indeed the same as that on the deceased Li Zhenbo, so I knew that there was a 90% chance that he was indeed electrocuted, and that the arsenic was eaten before his death, whether it was suicide or something, and I still can't come to a conclusion.

I asked, "Did you know that this electric heater was leaking?" ”

Wang Huizhen said: "This electric heater has always been good before, but that time, it leaked directly, and it was estimated that it was wiped with a wet rag, and Li Zhenbo didn't understand it very well, so he was directly electrocuted." ”

I was a little curious: "How did Wang Huizhen know that Li Zhenbo was electrocuted?" ”

I asked; "Did you check the body at the time?"

Wang Huizhen said: "I must have checked it, my heartbeat is gone, I don't breathe, the voltage is so high, I must have been electrocuted if I touched it with wet hands." ”

I thought: "The household voltage is 220 volts, let's not talk about whether you can electrocute people, this is common sense, I basically know it, and Li Zhenbo likes to read so much, it should be impossible to say that I don't know this common sense, if I know, and touch it, why in the end?" ”

I didn't think of superfluous questions for the time being, so I let Wang Huizhen go first, Li Zhenbo's childhood came out of her mouth, it is estimated that it is relatively bleak, but after adulthood, it is estimated that it is still the same as before, and the current state, it can be said that a large part of it is from the influence of his childhood that made him a middle-aged man with a strange personality.
