When I arrived at Director Wang's house, I found that there were six people gathered inside, in addition to Qiao Wei and Mr. Qi, there were also four middle-aged faces, all of whom were probably members of the Bazhai Hall.

Qiao Wei didn't introduce me to those people, but directly showed me the investigation certificate of the fire in the medical school in 07 that he asked a friend to get, which stated that the cause of the fire was a wire fire.

Qiao Wei said that the conclusion given in the certificate was too vague, and there was no mention of the possibility of arson at all, and he felt that there must be something else hidden in the fire.

I can't make up my mind about this yet, but I still have some say in the investigation of the cause of the fire, because I have a buddy who has been playing since I was a kid and is now working in the fire brigade and is also an officer leader.

I remember he once told me that the most difficult part of investigating the cause of a fire is the fire scene. In many cases, the scene was completely destroyed by fire, and it was difficult to pinpoint the cause of the fire, so in this case they had to infer from experience.

In addition, as long as there are no traces of abnormal accelerants or explosives at the scene, the possibility of arson is generally ruled out. The copy of the certificate did not contain the words accelerant or explosives, so from an official point of view, no one set the fire.

I told Qiao Wei everything I knew truthfully, and then I asked Qiao Wei again, and he would think that Old Man Qin's ghost refusing to leave must be related to the fire.

Qiao Wei replied that he returned to Director Wang's house at about two o'clock in the morning today, but as soon as he entered the door, he saw Old Man Qin. He was just about to disperse Old Man Qin's soul, but Old Man Qin actually opened his mouth to talk to him.

"He told me that he had died unjustly, and that he had seen something in the building that day. He also said that he knew that Da Ben was with me, he could feel it, and hoped that I would release Da Ben, and he would take Da Ben to find the truth. Qiao Wei briefly repeated Old Man Qin's words to me.

"Do you believe the words of ghosts?"

"Ghosts never deceive people, so when I exorcise ghosts, I usually use the spirit summoning to try to communicate with ghosts. It's just that the few times you have encountered are particularly unlucky, and they are all bad communication with ghosts and ghosts. ”

Qiao Wei's subtext is obviously to say that I have a relationship with evil ghosts, and he also redefined the idiom "ghost talk".

"Okay, then let's take the fire as a hypothetical one, let's analyze all the situations and see if we can find out what the clues are. Do you have pen and paper? ”

As soon as I asked, a fresh face with Qiao Wei immediately handed me a tablet, or the kind with an electronic pen—these gentlemen who studied ghost things were obviously much more up-to-date than me, the writer of books.

I didn't complain on this point, because the six people, including Qiao Wei and Mr. Qi, all looked at me in unison, as if expecting me to break through the deadlock.

I took a deep breath and said, "Since it is arson, there is a purpose, and when it comes to purpose, there are generally two points: the first is revenge, and the second is profit. ”

As I spoke, I wrote the words "revenge" and "profit" on the top of the clipboard, and then divided a few lines below them.

"If it's revenge, it could be against people, it could be against schools. Because the fire broke out in the second half of the night, and when there was no one in the laboratory building, the possibility of retaliation against people could be ruled out, and the only thing left was to destroy the school. And if it is for profit, you can also rule out the possibility of robbing while the fire is fired, and then it depends on who can profit from the fire in the laboratory building. ”

I wrote two separate objects under "Profit": medical school, real estate developer.

Then I continued: "First of all, the medical school can get an insurance payout, and the laboratory building is also old, so it is more cost-effective to come back with a sum of money than to directly dismantle it, and it can be regarded as waste reuse." In addition, after the fire, the medical school directly changed to a new location, which can be regarded as a good reason to relocate. So the fire is good for the medical school itself. ”

I wrote the words "losing money" and "moving to a new location" under "medical school".

"Next up are the real estate developers. Because the medical school moved away, this treasure land near the city center was vacated, and the real estate developers who got this land definitely made a profit. But the problem is that the real estate developer does not dare to guarantee that the fire will definitely make the medical school move, so it is a bit risky to use the fire to force the medical school to sell the land, unless there is a point, the real estate developer knows that the fire will definitely be haunted, but this contradicts the real estate developer's move to build high-rise buildings in the later stage. ”

So I wrote the words "treasured land" and "contradiction" under the word "real estate developer".

Zuihou: One of the most critical issues is the fire brigade's investigation of the fire scene.

"The investigation of the cause of the fire is very professional, if there are traces of accelerant, it will inevitably be discovered, since there is no mention of accelerant in the investigation certificate, it means that the arsonist did not use that thing at all. So how did the fire come about? Is there any way to make a fire for no reason? Qiao Wei, what is the fire brake, can you please explain? ”

This is a word I heard from Mr. Qi when I was chatting with him yesterday, and I have seen Qiao Wei make a large fireball more than once, so I want to make sure that Qiao Wei's fire charm can ignite combustibles.

Qiao Wei replied, "The Fire Flame is the highest form of the Demon Mantra of the Demon Town, although it cannot be ignited out of thin air, it can help the open flame to rise. But it's very difficult to set the whole building on fire with fire, no, it's impossible if it's not very difficult, it's not that powerful, at most ......"

"At most, set all the rune paper in a garbage can on fire, right?" I snatched the words.

Qiao Wei was stunned when he heard this, and it was obvious that he also recalled the strange form of ghost fire haunting that he had seen in the upper echelons.

"But it's also possible that someone lit a trash can with a lighter or a match or something, and the fire in the trash can ignited the wires." One of the four strangers asked.

"That's right!" I nodded at him, and continued: "If the fire in the laboratory building was only lit by someone with a lighter or match, then the arsonist should be the one who retaliated against the school, probably a student who was expelled from the school or something, and of course it may be the school's own people who lit the fire for profit. But what I want to focus on is the latter possibility. ”

I paused deliberately, and only after the attention of the six people was focused on me did I say, "There was a real estate developer who took a fancy to the land and wanted the medical school to move out, so he targeted the laboratory building, which was full of specimens, because he knew it would be haunted." So a few days later, the fire started, and then the ghosts also made a fuss, and then the medical school moved away, and the real estate developer also successfully got the land. But he knew that there were ghosts here, and it was not suitable for building a building, so he sold this land to another wronged man! ”

When I said this, all six of them in the room looked extremely surprised, and none of them raised objections or questions. Obviously, they are also willing to accept this inference made by my zuihou.

Over the next two days, the people of the Lent Hall used their connections to verify the possibilities I had listed. They were amazingly efficient, and on Monday, the answer was revealed, and the results surprised me, but they made sense.
