"Why didn't you say this detail?" , Nie Xiaohu was slightly displeased.

"This... I thought it didn't matter", Wang Ma lowered her head again, her voice almost inaudible.

"Is that so?" , Nie Xiaohu looked at Shangguan Yu and asked.

"Yes."

Shangguan Yu nodded and said: "I was in a depressed mood, so I opened the window, sat in front of the window and looked at the lake, suddenly a gust of wind blew in through the window, my left eye felt a foreign body, very painful, I couldn't open my eyes, so I wanted to go to my mother to help blow it, as soon as I opened the door, I saw Wang Ma was holding a tea tray in the corridor, so I stopped her and asked her to help me blow it." ”

"Gross!" , Shangguan Yu covered his mouth, bent over and walked out quickly.

Nie Xiaohu's brows were furrowed: "Miss Shangguan, are you okay?" ”

Shangguan Yu waved his hand back, and walked out of the living room, Cao Xiaohui didn't need Nie Xiaohu's instructions, and immediately followed, and Nie Xiaohu looked at Yang again.

"This...", Yang said with a slight embarrassment on his face, "Yu'er, she suffered from some wind chill yesterday, and her body was a little uncomfortable. ”

Nie Xiaohu thought for a moment, and then asked Wang Ma, "Who else have you met on the second floor?" ”

"Also... I also met Madame", Wang Ma's voice was like a mosquito buzzing.

"Ma'am?" , Nie Xiaohu turned to look at the Yang family, "Mrs. Kou, haven't you been staying in the room with Mrs. Li?" ”

"Oh, that's it", Yang seemed to remember something, and hurriedly explained: "I have been staying in my room with Sister Meng, but I went downstairs to go to the toilet halfway, and when I came back, I happened to see Wang Ma standing in Yu'er's door, as if she was blowing Yu'er's eyes, I didn't ask, so I went back to the room directly." ”

"Is that so?" , Nie Xiaohu looked at Wang Ma again.

"Hmm", Wang Ma nodded busily.

"What about you? Have you been lying in your room? Nie Xiaohu looked at Deng Xingdong and asked.

"Yes, my lord, look, I can't move even if I want to", Deng Xingdong glanced down at his injured thigh.

At this time, Cao Xiaohui accompanied Shangguan Yu back to the living room, Cao Xiaohui didn't speak, just nodded slightly at Nie Xiaohu.

"You, come with me upstairs!"

Nie Xiaohu pointed at Wang Ma, and then walked towards the stairs, Cao Xiaohui followed closely, and Wang Ma also followed cautiously.

Go up to the second floor, the first thing that catches the eye of the little tiger is a thick layer of felt on the floor of the corridor, the corridor is about 20 meters long is very clean and empty, there is a wooden frame on the left and right sides of the staircase, which is used for flower pots, at this time the two wooden shelves are empty, there are three rooms on the left side of the corridor, four rooms on the right side, all the rooms are not locked.

"Where's the storage room?" , Nie Xiaohu asked.

"That's it," Wang Ma pointed to the right side of the hallway, counting out the second room from the end.

"Who are the other rooms?"

"The room at the top of the right is the storeroom, and from this side is Junko's, mine, and Miss's room; On the left, from the head, there is the young master's, the lady's and the master's, the master's room is relatively large, divided into two rooms", Wang Ma pointed to each door and introduced it in turn.

Nie Xiaohu looked at the wooden frame on the left side of the corridor, which was placed on the right side of Shangguan Yu's door.

"Where did you put the tea set tray when you were blowing your eyes?"

"Oh, I just put it on that wooden shelf," Wang Ma pointed to the wooden shelf on the right side of Shangguan Yu's door.

"Where were you standing then, and where did your young lady stand?"

"I was standing here at that time," Wang Ma pointed to the door, "and the young lady stood by the door, leaning against the doorframe. ”

"How long did it take you to blow your eyes for Miss?"

"..., it's just a few breaths," Wang Ma thought for a while and said, "Soon, it'll be fine after a few blows." ”

"Why do you have to lay felt in the hallway?"

"This is what the master ordered, and he said to spread the felt, so that there will be no movement when walking, and it will not affect the rest of the others."

Nie Xiaohu pursed his lips, shook his head gently, and reached out to push open the door of Shangguan Yu's room.

Facing the door was an open window, and when you looked out at the rippling blue waters of the lake, it was already night, and the lake was sprinkled with silver moonlight, giving people a sense of tranquility and serenity.

Under the window is a small wooden table, on the wooden table is placed a set of tea sets, there is a chair on each side, the corner of the wall is a wooden bed, the other side is placed against the wall is a wardrobe, next to the wardrobe is a small dresser, and there are two landscape paintings on the wall, which are very simple furnishings.

Nie Xiaohu inspected the other rooms again, the furnishings in the rooms were roughly the same, all the rooms were separated by wooden boards, and there were no inner doors to connect them.

After inspecting the second floor, Nie Xiaohu asked Cao Xiaohui with a smile: "What do you think of this case?" ”

"It's unlikely that outsiders will commit crimes," Cao Xiaohui said, shaking her head.

"The tea set has been in the hands of Wang Ma from beginning to end, and the only people who can poison it are the people in this building, but how did the murderer do it? There is also a question, that is, how did the murderer know which cup Kou Yuanwai would choose, or was his target not Kou Yuanwai in the first place? I don't understand! Cao Xiaohui frowned and pursed her lips.

"And ......," Cao Xiaohui whispered a few words in Nie Xiaohu's ear.

"Really?" , Nie Xiaohu asked with a little surprise.

Cao Xiaohui nodded.

"It's getting more and more interesting!" , Nie Xiaohu smiled.

After returning to the living room, Nie Xiaohu glanced at everyone and said coldly: "Now in order to investigate the murderer, I want to inquire about you one by one, I will find a room upstairs, and those who are called will go upstairs, and the rest of the people will wait here, no one is allowed to talk to each other, otherwise they will be punished as criminals, can you understand?" ”

"Understood, sir," everyone nodded in response.

"Very good, now Li Yuanwai will follow me upstairs first!"

"Okay", Li Guanyu hurriedly stood up and followed Nie Xiaohu to the second floor.

In Kou Xuanwei's room on the second floor, Nie Xiaohu and Cao Xiaohui sat side by side, a chair was placed opposite them, Li Guanyu sat down in an orderly manner, the door was closed, and Shi Yuning and Mao Guangjian stood on both sides of the door.

"Li Yuanwai, what is your relationship with the deceased Kou Wanwei?"

"Uh..."

Li Guanyu frowned slightly, hesitated slightly, and then said: "My lord, I can't hide it, I don't have a deep relationship with Brother Kou, but I have some business dealings. ”

"Do you have a grudge between you?"

"Well, in fact, it's not a complaint, that is, last month, I wanted to buy a batch of Jiangnan silk from Brother Kou, originally we negotiated the price in advance, but when the goods arrived, Brother Kou asked me to add money, saying that this year's mulberry tree attracted insect plagues, and silk production was reduced, resulting in the price of silk.

I was very angry at the time, so I reasoned with him, and in the end we broke up, because I really needed that batch of materials urgently, so I still added money to him and bought it, but I couldn't get out of my breath all the time! ”
