What Director Huo said makes sense, the fire in the photocopy room may have nothing to do with whether the window can be opened.

Their school is a key high school, and both the teaching quality and the school environment are the best.

Their school was the first to install light bulbs, and even the photocopy room was equipped with lights, so there was no need for candles, so there was no fire hazard at all.

"I went to see the scene of the accident, and I found traces of candles on the table, and there was candle oil on the floor."

So, someone went in.

"Who is it?"

"Could it be a school teacher?"

"Impossible." Huo Yicheng did not hesitate.

The crowd looked at him.

Huo Yicheng analyzed: "There are indeed many teachers in our school who live on campus, but more of them go home every day.

The school is divided into male dormitories, female dormitories and faculty dormitories, and the dormitory doors are locked every night. ”

"I asked the housekeeper and he said there was nothing unusual last night. Even when the teacher came in, there were several questions that could not be explained. ”

"First, why did the teacher come to the photocopy room at night, what was his/her purpose, what was his/her intention?"

"Second, if the teacher came to the photocopy room, why didn't the dormitory see anyone coming out of the dormitory?"

"Thirdly, since you are a teacher, you will come, why do you come with candles instead of turning on the lights, is there any reason why you can't turn on the lights?"

"Fourth, the key to the photocopy room is difficult to obtain, there are three keys in total, one in the security room, one in my place, and one in the photocopy room teacher, how did the teacher get the key and enter it without knowing it?"

“……”

Huo Yicheng's four points went up to everyone's heart.

That's right, why.

Lin Yin thought seriously and did not speak.

After Huo Yicheng finished his summary, he looked at them: "You must get the answers to these questions in order to unlock the following questions." ”

The three year leaders pondered for a long time, but they couldn't think of a single reason.

"Since he/she chooses to go to the photocopy room in the evening instead of in the morning, it means that this can only be done in the evening, not in the morning."

Lin Yin suddenly spoke.

The three teachers, including Huo Yicheng, all looked at Lin Yin.

Lin Yin then analyzed: "The second and third are the same problem, if you can turn on the light but choose to light a candle, it proves that he/she doesn't want the patrolling security guard to know that he/she is in the photocopy room." ”

Because if the security guard sees a light on the side of the copy room, he will definitely come and take a look.

If it's a teacher, I'll say hello and say hello.

Obviously, the man didn't want the security guards to come over.

In other words, that person is not a teacher, so he is afraid to meet the security guard.

"The last question, how did that person get the key to the photocopy room, first of all, it has been determined that there are only three keys, one is here with Director Huo, Director Huo is sure that the key has not been stolen, and the second is in the security room, because all the keys are backed up in the security room in case of accidents.

But when there was a fire yesterday, there was a security guard who went to pick up the key, which proves that it was not the key that opened the door. So it can only be the third ......"

"You mean, this was done by the teacher in the photocopying room?!"

"Not necessarily." Lin Yin shook her head: "Now there are two possibilities, the first is like what the teacher said, it was done by the teacher in the photocopy room, and the second is ......"
