"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.
