On the train, Qiao Wei told me something about ghosts. In addition to the classification methods of geismas, soul-binding, resentful ghosts, and powerful ghosts, ghosts can also be divided into two categories: rooted ghosts and rootless ghosts. According to Qiao Wei, because people still have nostalgia or resentment towards the world after death, the soul of the dead is condensed and becomes a ghost, and the place where the soul is originally condensed is called the ghost root, and the exorcism of ghosts is a ritual done to the ghost root.

Generally, in the case of the bones being preserved, the ghost root must be the bones themselves, without exception, but sometimes the bones are gone, and the ghosts may fall on other things.

Whether it is a corpse or any other form of ghost root, it is possible to be destroyed, but this destruction will not make the ghost root disappear from the world. For example, the ghost stick is a tree, but the tree is cut down to make paper, and the ghost root turns from a tree to paper, and although the ghost root still exists, it is impossible to find the body, and the ghost in this case is called a rootless ghost.

Rootless ghosts can't consecrate and ascend to heaven through ordinary transcendent rituals, they can only clear their grievances or their nostalgia for the world, but this is obviously much more difficult than doing a ritual on the ghost roots.

On the way back to Heilongjiang, Qiao Wei told me that he felt that it was unlikely that the diary was a ghost root, and that once the consecration was not completed, then it would be up to me to help find out the real cause of Wang Dongmei's death to exorcise the ghost.

I've just read a lot of mystery novels and written a few mystery stories, but this doesn't mean that I'm an expert in solving crimes, and Wang Dongmei's death was sixteen years ago, and now to find out the real cause of her death, in addition to having profound skills in solving cases, it definitely depends on luck.

On the night we got home, Qiao Wei and I went to school with Wang Dongmei's diary. Qiao Wei chose the location of the back door of the suicide building to open the light, the whole consecration process is still very time-consuming, Zuihou's diary is also burned, and the four words of the consecration ceremony are also read, but I have never seen the thing that looks like light and smoke.

"Didn't it work? I didn't see the smoke. I asked Qiao Weidao.

Qiao Wei first frowned and nodded, then looked at me in surprise and asked, "Can you see the spiritual light?" ”

"It's that yellow thing that looks like smoke, right?"

"That's right! Can you see it? ”

"I saw you twice when I saw you open the light in Humpwaist Village, and I have never seen it before."

"That means we are destined! The aura is generally only visible to those who do the consecration ceremony, if you can also see it, it means that the aura of the two of us is very compatible, and under normal circumstances, I should accept you as a fragrant child! Qiao Wei was visibly excited.

Although I don't know the line of exorcism feng shui, I still know that Xiangtong is an apprentice, so I decisively waved my hand and refused: "Forget it, I don't think I have much talent in this area and I don't have much interest, thank you for your kindness, let's talk about this ghost thing, didn't the light work?" ”

Qiao Wei shrugged his shoulders and spread his hands and said, "It doesn't work, it's basically a rootless ghost." After saying that, Qiao Wei looked at me with that expectant gaze.

I hurriedly said, "Don't look at me!" This situation is more appropriate to find Tang Hui, he is from the criminal investigation department, and the cause of Wang Dongmei's death should have nothing to do with ghosts, which happens to be within his jurisdiction. It's your colleague, I think it's relatively easy to find him. ”

Qiao Wei thought about it for a while and agreed with my statement. Then he called Tang Hui first, briefly told Tang Hui about Wang Dongmei, and then made an appointment to meet tomorrow during the day to talk in detail. After hanging up the phone, Qiao Wei began to ask me what I thought about his colleague.

Because Qiao Wei's family is not in the city, he came here to stay in a hotel, just these days Shu Xin went back to her parents' house to live, I simply invited Qiao Wei to live at my house, on the way home I drove while telling Qiao Wei my thoughts.

In fact, what I think is very simple, first let Qiao Wei ask his uncle Taishi to determine if anyone in the Lent Hall knows the location of these buttons, the purpose is to rule out the possibility of the people in the hall committing crimes. If you are sure that it was not the people in the hall who did it, then go to the person who asked Uncle Qiao Wei to come out.

In short, it is to find all the people who know the location of the buttons, and then visit or secretly check them one by one. Because I don't think there are too many people who know the detailed location of all the buttons, and there is still a week before the female ghost reappears, so it should be enough.

Qiao Wei immediately called his uncle after listening to me, although it was already nine o'clock in the evening and it seemed not too good to disturb the old man's house, but Qiao Wei obviously wanted to determine the list that needed to be investigated as soon as possible.

Sure enough, the call was made several times before it was connected, and the subsequent call was quite long. It wasn't until my car drove home that Qiao Wei finished the call.

"There are only three people in the hall who know, one is my uncle himself, and the other two are my mother and me, so this side can be ruled out!" Qiao Wei hung up the phone and said to me directly.

"What about the school?" I asked.

"Uncle Tai said that there is only one person who follows the whole process of cloth buttons, Zhang Hongliang!"

Zhang Hongliang, sure enough, I heard this name! In fact, before Qiao Wei went to ask him about Uncle Taishi, I had already guessed that it might be him.

Zhang Hongliang is the president of my university, and he is also a man of the hour. As far as I know, Zhang Hongliang became the dean of the School of Management at the age of 38, and later became the president in 95, when he was only 43 years old.

After the joint-stock system of colleges and universities, Zhang Hongliang also became one of the directors and the only school leader among all board members. Up to now, Zhang Hongliang has been sitting in the position of principal for almost 20 years, and he has never planned to retire.

The reason why I know these things about Zhang Hongliang is because of a roommate in my college who completely regards Zhang Hongliang as his life goal. At that time, he always had a mantra on his lips: find a hard girl, and work hard for half a lifetime - Zhang Hongliang relied on his father-in-law's relationship.

I'm always very disgusted with this kind of person who climbs up by relying on his wife's family relationship, maybe I remember that so much information about Zhang Hongliang is also related to my hatred of him.

But hate it, I definitely don't believe that Zhang Hongliang will be the mastermind behind the use of ghosts to kill people in school, but from him, you can find out who else knows the placement of the button.

After arriving at home, Qiao Wei and I also arranged the whole day's actions for tomorrow. The first is to meet with Tang Hui, explain Wang Dongmei's matter to Tang Hui in detail, and then go to visit Zhang Hongliang.

How can I say that Zhang Hongliang is also the head of a school, he can be regarded as a busy person, and he can't see it if he wants to, so he has to ask Qiao Wei's uncle to help arrange it. Since Zhang Hongliang is a person who believes in ghosts and gods, I believe that as long as Qiao Wei's uncle speaks, he will definitely find time to meet the two of us, not to mention that this is a major event related to the reputation of the school, so I am not worried that Zhang Hongliang will put up a fight with us or something.

There is no need to worry about tomorrow, and you can sleep soundly that night. Qiao Wei slept in the single bed in my study, sometimes I like to stay up late to write, in order not to affect Shu Xin's rest, I sleep there directly, so the comfort is absolutely guaranteed, it is definitely much stronger than staying in a hotel.

I haven't had a good rest for a few days, and today I can finally lie in my own bed, this feeling is indescribably comfortable, so a long-lost lazy sleep is essential.

When I woke up the next day, it was already half past eight in the morning, and Qiao Wei also gave me a surprise.
