When Wang Shang was still worried about the eyes that he didn't know who it was, he didn't expect Sun Siwen to have found the key clue to the next incredible mystery. Pen ~ fun ~ pavilion www.biquge.info

"This photo, it is said that a lover of night aerial photography accidentally took it, the focal length, the light, nothing was adjusted, it was a complete accident." Sun Siwen snatched the meat skewers from the table as she spoke, and she didn't have a ladylike demeanor at all.

"This ...... Is it true? Zhao Zhiao was puzzled.

"I don't know." Sun Siwen swallowed a meat skewer and said without hesitation.

“…… I don't know if you're still so arrogant? Zhao Zhiao was speechless.

"I look very real, and the provenance of this photo is also reasonable, but I really can't be sure of the authenticity, otherwise I wouldn't have said that it was a key clue, but directly cracked it."

When Wang Shang heard this, he enlarged the photo and observed it carefully.

Seriously, the clarity of this photo is really very low, and you can't get any useful information out of it.

"It's a blurry picture...... Why do you say this is a key clue? Wang Shang couldn't help but be surprised, although Sun Siwen was very arrogant, but on these key issues, she had never been so unsafe, otherwise she would not have become the president of the Reasoning Society.

"Actually, at the beginning, I didn't take it as a clue at all, purely when I was searching for the blocked window, I accidentally found the photo, and I saved it because I thought it was meaningful, but now it's completely different."

"We have a high-ranking person from the school to help us now!"

It took Wang Shang a lot of strength to understand that Sun Siwen was talking about Director Zhang.

"If the piano that plays automatically is really played by someone sneaking into the music room at night, then it is clear why the phenomenon disappeared after a while." Sun Siwen began to analyze.

"Since the piano has been playing for several years, it is clear that this person is not a guy who gave up halfway, and the reason why the piano has stopped is because he is no longer in this school because of some things, so he can't continue to play the piano."

"In other words, if we look at the personnel changes of teachers and students in those years, a week before the sound of the piano played by the player disappears, if there is someone who leaves the school due to special accidents or personnel changes, can't we find out this person?"

When she said this, Sun Siwen stuffed the last string of meat skewers on the table into her mouth.

Wang Shang and Zhao Zhiao all looked at Sun Siwen dumbfounded, not because of her appearance, but because of the method she just said.

Indeed, considering the scientific nature, if you don't think in the direction of the supernatural, it is clear that someone played the piano that sounded automatically at night, and if this is the case, then the credibility of this photo is very high.

Combined with the time when the piano sound disappeared, as long as you have the heart, you can indeed find out the possible identity of this person.

Obviously, however, the investigator must be qualified to be able to recall the school's personnel transfer records over the years.

Wang Shang and the others did not have this qualification, so they did not consider this possibility at all at first, but Director Zhang was different.

As a person who once climbed step by step to the position of the vice principal of the second ladder of the school, even if he is demoted now, it is still the master level, as an elder of the school, it is not easy to read these materials, at least it will not pose a big problem.

If you could really ask him for help, it would be much easier.

"But...... Will he agree? We've bothered him enough about the window. Zhao Zhiao worried.

"If you don't agree, let's ask, right? It's not to force him to do this, just to ask him for help, what's the point? Sun Siwen took out the menu again and asked the boss to add dishes.

"That's true...... If we can investigate, it will be easier for us to confirm the authenticity of this photo, and it is only a matter of time before the piano is cracked. Wang Shang said.

"So that's it? We'll ask Director Zhang tomorrow to see if he can provide us with this information. Zhao Zhiao asked the opinions of the remaining two.

"I'm okay with that." Wang Shang naturally would not object.

"That's it! Tomorrow will be the same time and place, I will call Director Zhang in the evening and make an appointment with him. Sun Siwen said lightly.

"Wait...... When did you get his phone? ”

"Huh? Just now, we left each other's numbers when we chatted, after all, there may be something to trouble him in the future. Sun Siwen didn't find it strange at all.

In this regard, Wang Shang can only say that it is a kind of ability to be loved by others...... Fortunately, Sun Siwen is not the kind of scheming woman, otherwise there will definitely be many men who will be played by her.

"Anyway, it's settled, oh, that's right, this dinner is an AA system, and no one can afford to pay one-third of it alone!"

"What? Then you still eat so much, I protest! Only then did Zhao Zhiao react, almost all of the table just now went into Sun Siwen's stomach.

The three of them talked and laughed, of course, Wang Shang spent this celebration with a smile on his face, and everyone went back to sleep early for the plan of the next morning.

The next day, 10:30 a.m.

"You said that the school happened to save all personnel transfers through the computer that year, so it was easy to get worse? That's so much appreciated. ”

Everyone who had just arrived at Director Zhang's office heard a good news at the beginning, and Sun Siwen immediately stepped forward to express her gratitude.

"Don't worry, I've only told you good news, and there's bad news for you."

Director Zhang said unhurriedly, as if he didn't care much about the outcome of the matter.

Originally, although Director Zhang did master three of the seven inconceivables, he was not really a figure such as an inconceivable custodian, and Director Zhang's attitude towards the other incredibles was not to be ignored or curious, just to listen to the story.

"The bad news is that I can't find any changes in faculty or students during the time period you're talking about." Director Zhang said bad news.

"How so!" Zhao Zhiao exclaimed.

If this is the case, then the photo is likely to be fake, and the clues that everyone has managed to find will be broken here.

"That's true, and I calculated an extra week just in case, and it turned out that in this nearly a month, only one teacher was transferred back from other places, but there was no record of anyone being transferred." Director Zhang gave the final answer.

Having said that, Sun Siwen was naturally the most disappointed, she originally hoped that the person who wanted this photo to be real was her, but now she got such news.

Just as she was about to say goodbye to Director Zhang and look for clues again, Wang Shang spoke......

"Wait a minute, Director Zhang. I don't know if you can check the transfer records of non-teachers or students, school workers......" (To be continued.) )
