"Little girl, what do you know after a long time? Who is the murderer? ”

Wu Tianyi was so anxious, seeing that Yan Nuo didn't say a reason for a long time, he couldn't wait to shout.

"It's close, it's close, what the hell? Who the hell is it? ”

Yan Nuo frowned and shook his head fiercely, feeling that he was about to know the truth, but after chasing after him, the truth ran away, what the hell was it? What is the difference?

"Peiyun, do you have a headache? Should I take medicine? ”

Nan Qingyu glanced at her eyebrows slightly, watching Yan Nuo shake her head, could it be that she had a headache?

"Take medicine? Yes, yes, it's taking medicine. ”

The worse point is to take medicine!

Yan Nuo chuckled, reached out and patted Nan Qingyu's shoulder, "You are really powerful, you are so smart." ”

"Really? You don't know until now! Nan Qingyu raised his eyebrows, evoking a smile, and it was dazzling in an instant.

"Li Zhen, you still have to help me run errands."

Turning around, Yan Nuo walked towards Li Zhen and whispered.

"Yes, I'll go right away." After Li Zhen finished speaking, he quickly ran out of the academy!

"Peiyun, what the hell is going on?" Qu Yiyu became more and more confused the more she looked at it, and finally got it directly, and hurriedly asked Yan Nuo.

Yan Nuo took a deep breath, his heart began to complicate, and he sighed, his face was solemn that had never appeared before. She's conflicted right now. After hesitating for a moment, he said:

"Now, let's show how the murderer put the key from the outside of the house to the inside of the locked room."

Wu Tianyi frowned, and just as he opened his mouth to ask something, he was interrupted by Yan Nuo:

"I know you have a lot of questions in your minds right now, but please read them before you ask."

After speaking, Yan Nuo used a fishing line to penetrate through the paper door from outside the door, and gently tied one end of the fishing line with the "Dictionary Manual", and the other end was placed on the opposite door on the same floor, which was also in the same position of Shang Wenju.

Locking the door of Shang Wenju, Yan Nuo went directly to the second floor. Everyone was curious, and they also followed Yan Nuo to the second floor, the second floor is the sleeping building of Siyuan's study, which is the temporary residence of students and teachers.

In the same way, on the upper floor of the Yayuan Residence, tie the end of the key with a connected fishing line to form a pulley, and slowly retract the fishing line, and the key will follow Yan Nuo's retraction, and slowly slide down until it passes through the paper door of the Yayuan Residence and falls to the foot of the table in the house.

The "Dictionary Manual" on the table was used for tension and was dragged directly to the edge of the table.

"The murderer was too clever to use this method to return the key to the locked house."

Yan Nuo walked down to the second floor and looked around at the people present. Then he said:

"The murderer once entered this room, poisoned Zhou Dao, and then left. On the sly! ”

"Isn't the room locked? Are you saying that the murderer was carrying the key to Zhoudao's study at the time? ”

Wu Tianyi was finally clever once.

"Yes, the killer has the key." Yan Nuo replied blandly.

"Pei Yun, why did the murderer take such a big time to use the fishing line with the key and put the key back in Zhou Dao's study?"

"That's a good question." Yan Nuo glanced at Qu Yiyu, who looked surprised, and said slowly:

"Because the murderer wants to create a closed room murder case. In the locked house, in addition to the deceased, there is Wang Hongsheng, people naturally think that the murderer is Wang Hongsheng, because the house is locked, the key is also in the house, and the door has no key from the outside door, so naturally it can't be opened, only knocked open. ”

"Oh my God, that Peiyun, how did you know that the murderer used this method to blame Wang Hongsheng?"

Qu Yiyu's problems suddenly increased, and she couldn't see through it at all, she was obviously a little girl who was several years younger than herself, how could she be so smart? No wonder Huashang looked at this girl differently from the beginning.

"This murderer, wanting to kill Zhou Dao, has been premeditated for a long time."

Yan Nuo said, sitting on a stool beside him, leaning on the edge of the table, and then slowly continued to speak:

"From the dense holes on the Zhou Daomen, as well as the Shang Wenju opposite, and the same upstairs, it is not difficult to see from these holes that the murderer has experimented many times, and finally succeeded."

"Zhou Dao is usually a heavy drinker, so it is impossible for him to get drunk easily, and besides, if someone enters his study, he can't not notice it at all."

Wu Tianyi took two steps forward and asked Yan Nuo.

"Yes, he couldn't be drunk. But when someone enters the door, put a fancy incense? ”

Yan Nuo asked rhetorically, this is also his own guess, Zhou Dao is addicted to alcohol, and it must not be easy to get drunk, so with the murderer's cautious character, when he entered the door, he must have put incense or something.
