The villa design of Longxia community is relatively old-fashioned, after passing the entrance, the left hand is the nanny's room, the right hand is the hall, and the kitchen and the hall are connected. There is a walkway between the maid's room and the lobby, with floor-to-ceiling glass on both sides of the walkway and a small garden outside. There are two stairs at the end of the walkway, one up and one down. Down to the left is the entertainment hall, which has some home appliances for playing video and audio, and on the right is the study. Upstairs are a couple of bedrooms.

Chen Yiyan wiped a handful on the hallway, but did not find the dust, thinking that someone had been invited to clean it regularly. In the nanny's bedroom, except for some furniture, there are no personal belongings of the nanny, and no one should have lived in this room for a long time.

With some oil paintings hanging on the walls of the hall, Chen Yiyan walked to the kitchen and opened the refrigerator, which contained only some imported drinks and a few packets of noodles.

"It's true that as the head of the household said, they don't live here much." Chen Yiyan walked out of the kitchen.

"It's good to be rich, it's a pity to live in such a nice house." Lao Xing looked around the hall.

Yu Yuqian looked at the oil paintings on the wall.

"Is there anything special about these paintings?" Chen Yiyan walked up to her.

"No, I don't know much about this painting, but it looks pretty good." Yu Yuqian blinked her eyes.

"Oh. I don't know either. ”

Lao Xing heard Chen Yiyan's gentle tone, goosebumps gradually spread on his arms, and he immediately spoke: "Let's go, go to the study in the basement that the head of the household said." ”

"Okay." The two replied in unison.

The walkway was about ten meters, and the three of them turned left and went down the stairs, and Chen Yiyan turned on the switch on the wall.

The three of them first entered the entertainment hall on the left. "This TV is quite big, but it seems to be a bit old." Lao Xing said.

"Well, that DVD is also some years old, didn't the head of the household say it, after they bought it, the things here have hardly been touched except for the things that were taken away by Lin Xiaoyu and her grandmother." Chen Yiyan was flipping through the disc of the movie next to the DVD player, and Yu Yuqian was beside him.

"It's all some old movies that benefit the country."

"You've seen it?" Chen Yiyan asked.

"Well, I've seen a few. I've seen this, beautiful mind. Look good. ”

"I haven't even seen this! I'll take a look when I go back. ”

"There's nothing left here, let's go to the study." Lao Xing spoke.

The three of them came to the study on the right. The decoration of this study room gives the three of them a different feeling than the previous upstairs and entertainment hall. The study room is not big, only the size of an entertainment hall, with four walls, except for the side where they entered, the other three sides are equipped with huge bookcases, a wooden desk in the middle, only a retro lamp is placed on the desk, and there is a low table on the right hand of the door, and behind the low table are two two-seater sofas. The material and design of this desk, low table and sofa are the same as the bookcase, and they follow the luxury style of the royal family of Buenki.

"The decoration style of this upstairs is minimalist, including the entertainment hall on the left, but this study is in the royal design style of Buguo." Yu Yuqian expressed her opinion.

"What's the problem? Designed like this? Lao Xing didn't think there was anything wrong.

"Generally speaking, the style inside the house should be uniform, of course, it is not impossible, but the study is a little strangely designed."

"Maybe this Lin Dali likes to read, so this study is gorgeously decorated." Lao Xing touched the leather sofa on the side.

"It's possible, it's just a possibility." Chen Yiyan overheard the conversation between the two and sat down in the office chair behind his desk. Looking around, there was no safe. Pull open the drawer and there's nothing inside.

Lao Xing walked around the study a few times, there were all kinds of books on the books, domestic literary works, foreign well-known novels, economic and financial books, Lao Xing also saw a book about philosophy.

"This study, except that there are indeed a lot of books, there is nothing magical about it? Why didn't this Lin Dali let people in like this? Lao Xing said.

Yu Yuqian took a book from the shelf: "These books are all available in the market, and they are not valuable collector's books. ”

Lao Xing and Yu Yuqian looked at the books on the shelves, trying to find some information from them, while Chen Yiyan looked at the two of them, and he slowly spoke: "Do you feel the cold wind?" ”

"What cold wind?" Lao Xing turned his head.

"You mean, the head of the household mentioned it on the phone before?"

"Yes." Chen Yiyan looked at Yu Yuqian.

"Nope." Lao Xing remembered what the head of the household had said before.

Yu Yuqian also shook her head.

"I seem to feel it." Chen Yiyan said this sentence word by word.

The expression of the question mark appeared on the faces of the two opposites, Yu Yuqian put the book in her hand back on the bookcase, and walked to Chen Yiyan's side: "No?" ”

"I said Xiao Chen, were you frightened by the words of the head of the household?"

"Wait." Chen Yi extended his hand to stop Lao Xing's next speech. He turned his head to Yu Yuqian to the side: "Do you feel it?" ”

Yu Yuqian didn't answer immediately, everyone didn't speak again, and the study was quiet all of a sudden.

"It seems that there really is, and I feel it."

"Really!" Lao Xing has also come to Chen Yiyan's other side. "The head of the household is really right."

"Then wouldn't it be..." Before Chen Yiyan finished speaking, a faint feeling of vibration came. The amplitude of this vibration was very small, and it could only be felt when the three of them held their breath to feel it, or it was alone in this study in the middle of the night, Chen Yiyan estimated that the head of the household felt it like this.

"What's going on? The location of the sea market is not prone to earthquakes. Lao Xing held the table with his hand and frowned.

"Like an earthquake, but it doesn't have to be an earthquake."

"Well, I agree too." Yu Yuqian agreed.

"Is there any construction site nearby?" Chen Yiyan asked.

"When I drove over, I didn't see it. I'm going to ask the security guards. ”

Lao Xing contacted the security guard, and the security guard told him that this was not the first time that someone had asked about this matter, and the heads of the households in the area starting with B had reported this problem to the property. Later, the property came to check, and after checking for a long time, I didn't find any reason. This incident has also caused many householders to choose to rent out their rent, so most of them are some e-sports clubs or some self-media.

"We've done the math."

"What's the count?" When he came back from outside, Lao Xing, who had just told the two of them about it, asked.

"The interval between the wind and the tremors is usually five to six minutes and lasts for about a few seconds."

"And what does that mean?" Lao Xing said he didn't understand.

"Do you remember the head of the household who said why not sell the house?" Yu Yuqian spoke.

"Of course, housing prices are still rising."

"Yes, that's right, but he said it with one more sentence." Yu Yuqian added.

"Huh? Think about it. Lao Xing began to recall the content of the call.

He said that if it weren't for the subway here, housing prices would still be rising. Subway? Lao Xing grasped the key.

Chen Yiyan got up: "That's right! It's the subway. ”

"Are you saying the tremors and the wind are due to the subway? Impossible! My family lives near the subway, but I don't feel that way. ”

"Do you have a basement?" Chen Yiyan asked rhetorically.

"Well, that's not true." Lao Xing continued: "Are you sure it's the subway? ”

"Well, Haishi's Line 2 is only 1 kilometer away from here, I checked it just now, Line 2 is generally a shift every five minutes. There is no construction site in addition, so it should be the subway. When Lao Xing left, Chen Yiyan told Yu Yuqian his thoughts, and Yu Yuqian agreed with Chen Yiyan's point of view.

"What about the wind?"

"This wind is indeed very strange, I have seen it, this wind is blowing from below." Chen Yiyan pointed under the desk.

"Below?"

"Yes." Chen Yiyan affirmed: "And... ”

Chen Yiyan didn't continue, "And what? Lao Xing asked.

"It's nothing, you tell Xiao Yan to come now, this study has to be demolished." Chen Yiyan beckoned to Yu Yuqian and motioned to go upstairs. At the door of the study, he turned around and added: "Although we are investigating this case again, we still have to notify the local police station." Tell them to come. ”

When Lao Xing called, Chen Yiyan took Yu Yuqian to the second floor.

"This should be Lin Xiaoyu's room." Chen Yiyan looked at a room on the left side of the second floor and said.

Yu Yuqian walked up to him: "Hmm." Looking at the empty bedroom, Yu Yuqian remembered Lin Xiaoyu, who had been in contact with her on weekdays.

The two looked at the other rooms, and Chen Yiyan asked some questions about the decoration. What surprised him was that Yu Yuqian's knowledge in this area was so complete, according to her original words, if Yu Yuqian went to take a relevant design certificate, she could directly open a decoration company.

Just after four o'clock, the police station of the third district sent someone. The person who came was the person Lao Xing had entrusted before, and he was also his good friend, the deputy captain of the Criminal Police Team of the Third District, Officer Long.

"Lao Xing! A little time is gone. "Officer Long is tall and thin, slightly older than Xing Zhengyi.

"Brother Long, hello." Lao Xing stepped forward and shook the other party's hand.

"What? I was asked to look into the missing case on the phone, why did you call me again now? I don't make it clear on the phone. ”

"I want to make it clear to you, but I don't know, it's our police advisor who asked me to call you here."

"Your police advisor?" Officer Long was wondering who Lao Xing's advisor was.

"Officer Dragon! Long time no see! Chen Yiyan's voice came from the hallway.

"This is my assistant, you can just call her Miss Yu." After seeing Officer Long looking at him, Chen Yiyan introduced Yu Yuqian beside him.

"It's you kid! You seem to be doing pretty well lately! When Officer Long saw Chen Yiyan's face, he remembered some things from the other party's past: "How is it?" You said you were going to solve the bank robbery, are you still investigating? ”
