"Lin Xiao hid the fact that there was a gap between camera shots, right?" Zhen Gong said.
"But Mito-san didn't tell anyone about the time gap," Quan Tai said.
"My lady's alibi is completely different from Lin Xiao's," Mei Tu said.
"Didn't Xiaofeng also confirm Lin Xiao's alibi?" Baitian said.
"Xiao Feng and Lin Xiao haven't been together forever, have they?" Xiaochun said.
"The receiver rang when the two of them were together," the maid said.
"Since the receiver is in Lin Xiao's hands, it is naturally possible to fake it." Long Ma said.
"The receiver is actually in the hands of classmate Xiao Feng." Ji Wang said.
"That's Xiaofeng lying." Xiaoji said.
"As long as we continue the discussion, we will know whether I am lying." Xiao Feng said.
"Please believe me, classmate Lin Xiao is really not the murderer."
"So now if we regard classmate Lin Xiao as the murderer, we will give the wrong answer, and then everyone will be punished. I will never let this happen.
Even if I exchange my life for it, it won't happen."
Lin Xiao said: 'Classmate Xiaofeng.'
"Xiao Feng is right, I also think Lin Xiao is not the murderer."
"Quan Tai also believes in Lin Xiao. If he is a gentleman, he will trust his friends until the end."
"In this case, who is the murderer?" Ryoma said.
"It seems that we have discussed all the doubts in order to find the murderer," Mamiya said.
"There shouldn't be anything else that should be discussed. Let's think about it together." Xiao Feng said; "Isn't that right, classmate Lin Xiao?"
"Forehead?"
"Because classmate Lin Xiao is obviously not the murderer, but he has been silent since just now. It's not because you noticed the truth, so you will keep silent." Xiao Feng said.
"Because you're afraid of revealing the truth!"
"As expected, I guessed it right, but classmate Lin Xiao, you should answer, what truth did you discover?"
"Don't be afraid, tell me. This is not just for me, but also for everyone. Please face the truth bravely."
Lin Xiao said: 'It's a photo, the photo of Tianhai about to be killed taken by the camera facing the secret door.'
"I have never been able to understand Tianhai's actions at this time."
"Why can't you understand?"
"Judging from this photo, Tianhai-san is going to dismantle the camera, but that means he discovered the camera we set up."
Lin Xiao said.
"That's true, but when did he discover it?" Rotor said.
"I think it was probably when the first photo was taken by this camera. This photo was taken because Tianhai moved the bookcase. At this time, he noticed the camera for some reason."
Lin Xiao said: 'That's why he wanted to remove the camera. At that time, his hand left the bookcase, and the bookcase took charge of itself, so the sensor detected the movement of the bookcase again, so the last photo was taken.'
"And the reason that made him notice the camera, is there any secret in it?"
"There's nothing wrong with me, but the others don't understand at all. Tell them the key points quickly," said Meitu.
"I have been thinking about the reason why Tianhai noticed the camera." Lin Xiao said.
"And the answer lies in this photo."
Well, classmate Lin Xiao discovered the reason why classmate Tianhai noticed the camera.
"Flash, right?" Xiao Feng said.
‘Ah, flashlight.’ Mengye said.
"Well, the camera that was shooting towards the secret door turned on the flash when taking the picture. It was because of the flash that Tianhai discovered the camera."
"Why did you find the flash?" Rotor said.
"Comparing with other photos, you can see that I was also photographed when I removed the camera. This is the photo I took after removing the camera near the main entrance.
This is the photo taken by the camera near the back door, and the photo of Tianhai."
"Oh, the brightness of the figure in front is obviously different."
"Obviously in the same room and situation, taken with the same disposable camera, there is such a big difference in brightness."
"This is because the camera can only shoot towards the secret door and turn on the flash." Lin Xiao said.
"Why turn on the flash? Then the point of hiding the camera is lost, right?"
"This is not a simple mistake, right?" Xiaochun said.
"Well, it should have a purpose, which means that the camera has other uses besides hiding things." Lin Xiao said.
"Other uses?" Xiao Feng said: "It is used to lure people who move the bookcase to the position of the camera."
“That’s why I turned on the camera’s flash and deliberately let the other party discover the camera, and it actually succeeded.
Tian Hai, who was moving the bookcase, noticed the flash and came to the location where the camera was hidden."
"Although it was unexpected for the murderer to take a photo because the bookcase was closed at that time."
"Hello, Xiaofeng?" Bai Tian said.
"Ah, what's wrong with you? Have you been acting a little weird from the beginning?"
"The series of speeches you just made seemed quite certain," said Zhen Gong.
"Do you already know who the murderer is?" Rotor said.
"Well, I know. To be precise, I actually knew it a long time ago." Xiao Feng said.
"Huh? Did you know it a long time ago?" Quantai said.
"Because only one person can turn on the flash of that camera, right, classmate Lin Xiao," Xiao Feng said.
"So the murderer of this incident is...Classmate Lin Xiao, let you announce it."
It seems to have ended here.
In the end, I still couldn't do it. In the end, I still couldn't find out the true identity of the mastermind behind the scenes. I'm sorry.
"The reason why you haven't spoken a word is because of what happened, right? But this won't work."
"Although I may have stopped here, at least I will entrust you with my heart. From now on, I will rely on your efforts to protect everyone."
"Xiao Feng, you probably want to leave it to me, but this is too cruel."
Lin Xiao said: "Although it is cruel, I know that I will work hard to get what you want to entrust to me."
"I won't let your thoughts go to waste."
"The murderer is classmate Xiao Feng." Lin Xiao announced.
"What?" Quan Tai said.
"How is that possible, right, Xiao Feng." Rotor said.
Xiaofeng remained silent without saying a word.
"Is it really true?" Bai Yin said.
"Ah hahaha, I'm just kidding." Xiao Feng said.
"Are you kidding?" Long An said.
"Do you really think I am the murderer?" Xiao Feng said.
"It's disgusting, how is that possible?"
"Because when classmate Tianhai was killed, classmate Lin Xiao and I were monitoring the classroom together, and then we went to the library and found the body there."
Xiaofeng said: "Besides, I haven't met Tianhai at all, so it's impossible to kill him."
"Yes, classmate Xiaofeng cannot be the murderer." Quan Tai said.
"Really, isn't that for sure? Do you think I have the strength to hit someone with such a heavy shot put? My hands are used to press piano keys." Xiao Feng said.
"Then he just said you were the murderer?"
"Oh, it's classmate Lin Xiao who is joking. He just wants to lighten the atmosphere, right classmate Lin Xiao." Xiao Feng said.
"No matter how much I think about it, it's impossible for me to kill Tianhai-san."
Classmate Xiaofeng hopes to reveal the truth, so this is it.
"No, I'm not kidding, there is no doubt that Xiao Feng was the one who killed Tianhai." Lin Xiao said.
"Since you can be so sure, it seems that you are serious, Lin Xiao." Zhen Gong said.
"Well, of course." Lin Xiao said.
"Then can you tell me how I used a shot put to kill classmate Tianhai."
"If Xiaofeng had not been with Lin Xiao all the time, it would be impossible for her to do it." Bai Tian said.
"For this method, just think about where she used the shot put." Lin Xiao said.
"What does this mean?" Ji Wang said.
An Qi: “I don’t understand it at all.”
We can't escape now, we must respond to her and face the truth.
Xiao Feng said, "I'm not here to prove my alibi. When classmate Tianhai was killed, I was in the classroom with classmate Lin Xiao."
"Yeah, it's impossible to do it without meeting classmate Tianhai at all." Quan Tai said.
"The key point is that the location where the murderer used the shot put must be the library." Xiao Feng said.
"No, the place where Xiaofeng used the shot put was not the library at the crime scene, but the classroom on the first floor that we used for surveillance."
Lin Xiao said.
"Wait a minute, how do you use the shot put in the classroom on the first floor to kill Tianhai in the basement?" Ryoma said.
"With a throwing ball, classmate Xiaofeng threw a shot put from the classroom on the first floor and killed Tianhai in the basement." Lin Xiao said.
"What kind of magic ball is it? It's impossible." Mengye said.
"If you're willing, just throw it somewhere in the classroom and the shot put will move to the library," Lin Xiao said.
"It seems that classmate Lin Xiao has also discovered this." Xiao Feng said.
However, I don't want to find out, but I have no choice but to take another step forward.
"It's the vent in the classroom." Lin Xiao said, "As long as you throw it there, the shot put can move to the library."
"So that's it, that ventilation pipe connects the library and the classroom." An Qi said.
"So if the shot put into the vent of the classroom on the first floor will pass through the pipe, it will roll out from the bookcase in the library." Lin Xiao said.
"But how to hit Tianhai classmate from there? The vent is still quite a distance from Tianhai's body," Rotor said.
"Did you hit it by accident?" An Qi said.
"That might be just right." Bai Tian said.
"Ordinary makes people care."
Of course, this was not accidental, but carefully designed. Yes, when I think back carefully, her actions at that time were very strange.
If it can be discovered, now is not the time to look back on the past.
I have decided not to escape anymore and have made an agreement with her.
"How can the lead ball rolling out of the vent hit Tianhai?"
"Isn't it possible?"
"If you let the shot put roll down, it will be impossible to hit it perfectly. The probability is too low."
"Or did the shot put fall to the ground and trip over Tianhai-san, then hit his head?"
"Be careful." An Qi said.
"Tianhai was hit from below, and then moved a few steps while dying frequently," Meitu said.
"Classmate Lin Xiao, don't get lost in the truth." Xiao Feng said, "Don't run away from the truth."
"The shot put actually rolled on the bookcase and fell on Tian Hai's head." Lin Xiao said.
"Scrolling on the bookcase? Momota said.
"Although I said this myself, is the shot put really such a coincidence?" Ryoma said.
"No, the shot put didn't happen just right. Where it rolled, this was also part of the murderer's plan." Lin Xiao said.
"The murderer used the books on the bookcase to adjust the direction in which the shot put rolled."
"How can I adjust the rolling direction of the shot put with a book?" Bai Yin said.
‘Well, it would be easier to explain this with a floor plan, Mito-san, you must have said that during the investigation.
You want the toy airplane to be used to create the correct floor plan of the real thing.”
"Then what happened?" Rotor said.
"Ah, the photos have been developed and the floor plan has been prepared." Meitu said.
"Then let's take a look at me together, maybe it will be a clue," Quan Tai said.
"Please, Miss Meitu?" Lin Xiao said.
"Why do you want that? There's nothing you can do about it." Meitu said.
"It's exactly what I thought." Lin Xiao said after looking at the floor plan.
"What do you think?"
"Look at Tianhai's corpses arranged in a staircase shape from the vents," Lin Xiao said.
"Ah, really?"
"It does form a staircase from the vent, and you can't even notice it when you look from the bottom up," the maid said.
"I see, that's how it went."
"Exactly like this, the lead ball thrown into the vent of the classroom on the first floor passed through the pipe and rolled to the vent of the library, and then just leaned the cover of the vent there.
This should prevent the shot put from stopping and continuing to roll on the bookcase.”
Lin Xiao said: 'Xiao Feng did this, right? At that time, you really adjusted the position of the vent cover, right?'
"Classmate Lin Xiao, you have a really good memory. You really deserve to be a detective." Xiao Feng said.
"Then the lead ball rolled onto the bookcase and hit the stack of books used as a buffer and changed direction."
"Climbing a stair-like book is like going down stairs."
"There are three rows of books on the bookcase. The outermost layer of books is stacked very high. It is a wall to prevent the shot ball from falling, and it can also be used as a shelter."
"Then when the shot ball rolled directly above Tianai, it hit the book wall again and changed direction. It rolled along the opened book and fell on Tianhai's head."
"Tianhai was attracted by the flash of a hidden camera, so the shot put fell right on Tianhai's head," Lin Xiao said.
"This kind of mechanism that is continuously pulled by several devices is simply like a dew cloth device." Bai Yin said.
"This mechanism was made by Xiaofeng?" Bai Yin said.
‘Yes, that’s it.’ Xiaofeng said.
"Wait a minute, even if there was such a mechanism, when did Xiaofeng throw the lead ball into the vent?" Bai Tian said.
"Yes, classmate Lin Xiao, you were with classmate Xiaofeng when she was in the classroom on the first floor."
Lin Xiao said: "The moment we rushed out of the classroom, when the receiver rang, I rushed out of the classroom first, and of course classmate Xiaofeng quickly caught up with me.
But when she hesitated for a few seconds, it was probably that time."
"You remember what happened at that time very clearly. You are truly worthy of being at the super high school level." Xiaofeng said.
"Your words and that smile can be regarded as your admission of your crime, right?" Zhen Gong said.
'Wait a minute and don't jump to conclusions without permission, there are other doubts.'
"Hehe, it's strange why Momota wants to refute so hard." Xiaoji said.
"Of course, Xiaofeng, who has been cheering everyone up, how could he be the murderer?" Bai Tian said.
"Yeah, Quan Tai doesn't believe it either." Quan Tai said.
Bai Tian: "Xiao Feng, don't say anything, I will help you clear your suspicion!"
"It's actually acceptable to say that Xiaofeng's method is the best, and there are still some unsolved doubts."
