Tang Xianti slipped through the potatoes and knocked on the door of 2001: "Uncle Chen asked me to bring you potatoes up, and by the way, I will ask you about the situation", 2001 only opened a crack in the door as usual, and stretched out his hand to reach the potatoes.

Tang Xian asked tentatively, "Can you let me in?" With a bang, the door closed, and no matter how Tang Xian knocked, the door didn't open.

"The potatoes are at the door for you, I'll ask others", Tang Xian had no choice but to go to the 16th floor first.

1601 was a strong man with a full beard, the man was eating potatoes, and said vaguely: "It's good if you call me Xiao Chen."

Tang Xian asked curiously, "Are you related to Uncle Chen?" Who do you think is most likely to be a ghost in the building?"

The man shook his head: "We are from a village, our village is poor, it was Uncle Chen who took us out of the village to work, and found such a good house for us, and also found a daughter-in-law for us, you must find out who is pretending to be a ghost and not letting us take the money."

Tang Xian poked his head into the room and asked, "What about your wife?"

The man's expression changed, and he stammered, "Death... died, died in childbirth when giving birth". "Is the kid still there"? Tang Xian asked.

The man leaked a smile again: "The child is fine, it's a male baby, and Uncle Chen sent him to school."

"Did you hear a knock on the door last night"? Tang Xian asked another question.

The man was a little flustered: "I slept to death, I didn't hear anything, are you done asking?" I'm going to sleep."

Seeing that he couldn't ask anything, Tang Xian said goodbye to the man and knocked on the door next to him.

After asking the rest of the households, Tang Xian touched the cat's head: "Why are these men all dead wives and their children go to school"?

Tang Xian's five people met at Li San's house, and Xiaomei spoke first: "On the 2nd floor, the 3rd floor is a family of three, and the parents have their daughters."

Akui also said: "The 5th floor is also the daughter brought by the parents."

Li San was puzzled: "My 10th, 11th, and 12th floors are all widowed men, and the 8th, 9th, and 10th floors are a family of three, and my parents bring my daughter."

Tang Xian continued: "Me too, except for 2001, when the door was not opened, the other residents are all widowed, and there is a child who goes to school outside."

Li San concluded: "Then it is confirmed, now 601, 1901, 1902, 1801, 1802, 1701, 1702, 1401 no one lives, 401, 702, 1301, no one lives before 2002, we just need to find out who is pretending to be a ghost in the household."

Akui retorted: "This is a supernatural copy, the real murderer should be a ghost, I think it is more important to check the house where no one lives."

Tang Xian also put forward an opinion: "I looked at the residents before the empty room, except for Wang Dazhu in 601, how many of the other names have more feminine names like Mei, Xiu, and Cui, will they be the wives of those men?"

"It's not early, it's too dark and it's not safe, you guys go back first." Li San urged.

Tang Xian returned to 2002 with Luo Qi'an in his arms, and looked at the door of 2001 before entering, and the potatoes had already been taken in.

At two o'clock in the morning, Tang Xian was woken up by the sound of knocking again, this time it was not a knock on the door, but it was like the sound of chopping meat filling, and then the 3 mobile phones that Tang Xian put on his side suddenly lit up.

Tang Xian picked up his phone and saw that it was the same text message, "Did you hear any sound?" - 1902 - Pandan".

Tang Xian got out of bed silently and lay on the ground to listen to whether there was a sound in the empty room downstairs.

"Woo woo woo" is the sound of a woman crying. The crying sound was getting closer and closer, and finally it seemed that there was only a wall between him and Tang Xian, Tang Xian didn't dare to move, and quietly listened to the sound of chopping meat and the cry of the woman.

Luo Qi'an turned into a human form, picked up 1401's mobile phone and replied: "I'm so scared, what should we do?" - 1401-Liu Erya".

After the text message was sent, the crying stopped, and then Tang Xian heard the door close in 1902.

At 9 o'clock the next morning, Tang Xian went downstairs with Luo Qi'an, who had turned into a black cat, and by the dim light, Tang Xian found that there were bloody handprints on the door of the room where someone lived.

"There are a few families who haven't come down today, and they seem to be scared by last night's movements." Tang Xian and a few people sat at Xiaomei's house and summarized.

Tang Xian asked, "Did you hear anything last night?"

Xiaomei and Akui shook their heads, and Li San raised his hand: "I received a text message from 1902 last night, I didn't dare to reply, and after a while, there was a knock and crying on the fourteenth floor."

"Yesterday in 2002 I heard the sound of crying and chopping meat, my three mobile phones all received a text message from 1902, I replied with a mobile phone of 1401, and Xianglan of 1902 went downstairs to find Liu Erya of 1401."

Aqua scratched his head: "Who is the real murderer?"

Xiaomei was a little irritable: "The copy is called a dangerous building, it should be looking for the person who caused this building to become a dangerous building, my mother and I went to knock on the door of the five families who didn't go downstairs to get potatoes, all of them were not opened, I used props, and found that they were all dead."

"Old Uncle Chen, can you take us to see these five families, their doors can't be opened, we..." Before he finished speaking, Lao Chen took the key and came out: "I'm too old to get in the door, you can go and see."

The four men on the 10th and 11th floors and the family of three on the 9th floor, without exception, were chopped up at home.

In the cry of Uncle Chen's wife, Tang seemed to know that the man on the 9th floor was the nephew of Uncle Chen's wife.

Something so big happened that everyone gathered on the first floor for a meeting. The women curled up in the corner with their daughters, and the men surrounded Lao Chen: "Uncle, let's call the police" I don't know who opened his mouth first.

"No", Lao Chen shouted with red eyes, and then realized that he had lost his temper, and softened his tone: "I mean, the people above told me that the demolition money can come down in the next few days, and we will call the police now, and we won't be able to guard this building, and when the money comes down, we will immediately call the police My nephew was also killed, and I am also sad."

The men seemed to be convinced, and no one spoke again. A woman cried, and Lao Chen waved his hand: "It's getting dark, go back."

When Tang Xian went upstairs, he tried to call the police with his mobile phone, but the phone could not be called. Tang Xian stroked the cat: "I have a bad premonition."

Li San returned to 1301, his mobile phone lit up, and it was a message from a resident of 1402, "I have a clue to tell you."
