Coming out of the Yanju Office...

Lu Qiyuan said to Tan Yi: "Xiao Tan, although the daily report is biased, it has caused adverse effects, right?"

Tan Yi said: "I understand."

Lu Qiyuan nodded, "That's good, I'll give you three days, hurry up and solve the case."

Huang Zhenyi was surprised, "Lu Detachment, isn't the time too tight? The hospital has a mixed staff and can't provide technical support. It all depends on investigation. I'm afraid three days won't be enough."

Lu Qiyuan said: "Try hard."

Huang Zhenyi looked at Tan Yi helplessly.

Tan Yi said: "Okay, I'll do my best, Lu Detachment, Deputy Huang Detachment, I'm going back to get busy."

Tan Yi went downstairs.

Lu Qiyuan smiled and said, "Tan Yi is a newcomer, and the Second Battalion is mostly composed of veterans. They are already tired. Only by pushing them can they speed up."

Huang Zhenyi smiled and said, "Team Lu has studied our Second Battalion very well."

...

Tan Yi returned to the office and called the Household Registration Department, asking them to help him find Pi Yan's identity information.

As soon as he put down the phone, Fu Da knocked on the door and came in, "Captain Tan, there are a few more tabloid reporters at the gate."

Tan Yi frowned and said, "Tell everyone, don't pay any attention to them. I will punish anyone who talks too much."

Fu Da reminded, "Captain Tan, is this not good?" Tan Yi said, "It doesn't matter whether it's good or not. We are in criminal investigation and we don't do showmanship. We should leave this kind of thing to professionals." Fu Da was very

surprised.

Da Ai listened, "Okay, I'll notify them now." He took two steps outside and stopped again, "Is there still a meeting?"

Tan Yi said, "No meeting, and you don't have to go to the hospital. You make arrangements and continue to pay attention to Hou Zi'an's two opponents, as well as Li Xiaoming and Wu Meili. And Pi Yan, this person is not simple, you and I will go together later."

Fu Da said, "Where is Zhang Xiuyu?"

The phone rang.

Tan Yi put his hand on the receiver, "Hou Zi'an is more beneficial to her if he is alive, don't worry about it for now, go and notify them first, and then come back to find me."

Fu Da went out, and Tan Yi picked up the phone...

The people from the household registration department had a reply-Pi Yan, 38 years old, married, registered in Qingshanya, his wife Xing Xiaolian, 36 years old, they have two sons, the older one is 14 and the younger one is 12.

Currently living at No. 112 Huimin Street.

Tan Yi packed up the things on the desk, put on his backpack and left the office.

Fu Da asked, "Captain Tan, are you going out?"

Tan Yi nodded, "Let's go together."

The two drove to the Yangguang neighborhood.

Tan Yi pointed to the famous cigarette and liquor store across the street, "I have met Pi Yan, but it is inconvenient for him to show up. Go next door and ask who owns this store? How much is the rent per month?"

Fu Da understood, "Okay, I'll be back soon."

Tan Yi lit a cigarette and just took two puffs when Chai Yu called.

"I say, Old Tan, what are you busy with every day? You never call me."

"If you want to slander someone, just say it directly. There's no need to beat around the bush."

​​"Hahaha, Holmes Tan, what's wrong with you? Why are you in the newspaper?"

"..."

"I say, Old Tan, I know your strength. Don't get angry. I'll have a couple of drinks with you tonight."

"If you want to drink, find someone else. I'm busy."

"Oh, don't be so heartless. People can't tell you what's in their hearts."

"Wait until I solve this case."

"When will it be? It's better to do it today than to wait for a better day. Let's do it tonight. I..."

Tan Yi hung up the phone and flicked the cigarette ash with his index finger. "Shut up."

Fu Da came back. "The store here was developed together with the Yangguang Community. Most of the owners are owners of the Yangguang Community. They don't know whether Pi Yan rented the house. Why don't we go to Dingsheng Real Estate? They have the registration." Although it

is legitimate to go to the Real Estate Bureau to change the name, the real estate company's sales office is closer and can be reached by turning a corner.

Fifteen minutes later, the two got the first-hand information.

The two talked while walking.

Fu Da said, "I never thought that the property rights belonged to Pi Yan's wife. Pi Yan is with a rich man... Shit, Pi Yan is cuckolded."

Tan Yi said, "It's almost certain. Let's go to Huimin Street."

Huimin Street is behind "Famous Cigarettes and Wines" and is a row of bungalows. The street is straight and easy to find. The two of them found the place without asking.

The Pi family probably rented the house. The upper room was clean and tidy. There were a lot of miscellaneous items piled outside the east wing. There was a long rope tied in the middle of the yard, and the rope was full of wet clothes.

"Who are you looking for?" A middle-aged woman came out of the west wing and looked at Tan Yi and Fu Da warily.

Fu Da stepped forward, "Sister, is Xing Xiaolian at home?"

The middle-aged woman said, "Xiaolian went back to her parents' home early this morning and will be back in a few days. Who are you? I'll tell Pi Saner when he comes back."

Fu Da said, "Thank you, sister. That's not necessary. We know where Pi Saner is."

"You're welcome." The middle-aged woman turned around and went into the house.

"Sister, please stay." Tan Yi spoke and took out his police ID from his bag. "We are police officers from the Municipal Bureau. We would like to ask you about the Pi family. What is your name?"

"Police officer!" The middle-aged woman was startled. "My last name is Wang. What happened to the couple?"

Tan Yi said, "It's not a big deal. Just answer truthfully."

"Okay, okay, go ahead."

"How is the relationship between the Pi couple?"

"Very good. Pi Saner is a good man. He holds his wife in his hands for fear of dropping her, and holds her in his mouth for fear of melting her."

"Don't they fight?"

"No fighting. I've never seen them quarrel."

"What does Xing Xiaolian look like?"

"Oh, she's so beautiful, with big eyes and double eyelids, and she's fair and clean. She's much more handsome than Pi Saner."

"Have you ever seen Pi San in a bad mood?"

"This... well... I think so. Sometimes he always stands alone at the door smoking, and his face looks scary, but he has never lost his temper. Maybe I'm overthinking it. What happened, you two? Pi San'er is a very nice person. He helps his fellow villagers when they come to his house to stay overnight, buy things, or go to the hospital for medical treatment. He is very enthusiastic." "

Are there any mice in your house?"

"No, we have plenty of wild cats here, and the mice we have have been eaten."

"Okay, thank you, sister. If possible, you'd better not tell Pi Yan about this."

The middle-aged woman covered her mouth subconsciously, "Don't worry, don't tell us. We don't know anything."

The two returned to the police station, and there were few people in the office.

Fu Da went to the interrogation area for a walk, but when he didn't find the person he was looking for, he came back up and sat down on the chair opposite Tan Yi's desk. "Captain Tan, I'll go to Qingshan Cliff."

Tan Yi said, "We have to go to Qingshan Cliff, but before we go, we should check where Hou Zi'an has been working and what kind of projects he has been doing since fourteen or fifteen years ago. We should also look for the workers who worked with him at that time to see if we can find any traces of the Pi couple."

Although it would be more direct to go to Qingshan Cliff to find Xing Xiaolian, it would take at least twenty-four hours to go there and back.

"Yes, this is faster. Okay, I'll go there now." He walked out quickly.

...

Fu Da came back at three in the afternoon and found Tan Yi in the office. "Captain Tan, I found out."

Tan Yi took out his notebook. "Pi Saner worked in Hou Zian's construction team?"

Fu Da rested his butt on the corner of the table. "Not only that, Xing Xiaolian also worked as a cook on Hou Zian's construction site. They came to the construction site together after they got married, but suddenly they stopped working there. Pi Saner found a job selling goods and that's it." She never left the construction site again. Captain Tan, I guess Xing Xiaolian was raped by Hou Zian, and Hou Zian paid to settle the matter, but Pi San still holds a grudge against her.

Tan Yi added, "Pi San doesn't have the connections to open a famous hotel, but it's equally likely that he makes money by selling his wife. Have someone keep a close eye on Pi San, because he's cunning, and Xing Xiaolian may not really go back to Qingshan Cliff. At the same time, we have to prevent him from doing anything desperate."

"Okay!" Fu Da said with conviction, "Captain Tan, don't worry, we'll make all the arrangements."

...

Although the leaders did not criticize the Second Brigade, the people in the Second Brigade were still very angry. No one was lazy anymore, and fewer people were talking nonsense. Everyone worked together to cooperate with each other and try to give this slap back as soon as possible.

Li Ke and Li Ji were young and energetic. They spent a day and a night in the old city. Finally, on the morning of the fourth day after Hou Zian's death, they caught a small vendor who went to the countryside to sell medicine and brought him back to the city bureau.

When Xie Qing got off the car, she saw Liu Feng holding someone down.

Li Ke, with two dark circles under his eyes, said with a smile: "This is the last one. We finally caught him."

Xie Qing raised her thumb. Li Ke was also an anomaly among the girls. She was a strong woman.

Li Ke said: "It's the last one. Are you coming?" She meant that the source of the poison in Hou Zian's case has not been found yet, and success or failure depends on this move.

Xie Qing looked at Cao Haisheng.

Cao Haisheng said, "We can sort out the information when we get back. You go first."

Xie Qing bowed and said, "Thank you, Master."

Cao Haisheng smiled and waved his hand.

The sisters followed Liu Feng to the interrogation room. When they reached the door, Xie Qing stayed outside to listen to the interrogation recording, while Li Ke went in to take notes.

Li Ji poured the contents of the cloth bag onto the table.

As usual, Liu Feng asked the man's name, put on gloves, and picked up a paper bag. "What is this?"

The vendor answered honestly, "Rat poison."

"What rat poison?"

"Rat poison! It's really used to kill rats. Don't think too much about it."

"Someone has been poisoned to death. How can you not let me think too much!"

"Ah?" The vendor shuddered with fear. "It wasn't me. I wasn't home these days."

Liu Feng said, "Even if it wasn't you, it was the medicine you sold. Now I give you a chance to redeem yourself. Whether you can catch the murderer depends on you."

The vendor trembled with fear. "It's unfair. I'm not the only one selling this medicine. Why do you say it's my medicine?"

Liu Feng said, "Don't be cunning. Explain the problem. Have you been to Qingshan Cliff?"

"Qingshan Cliff is too remote, I haven't been there."

"Have you sold it in the city?"

"Yes, mainly in the old city."

"How many have you sold in the past twenty days?"

"This... They say a good memory is not as good as a bad pen. It's all in that notebook. I even remember where I sold it."

Li Ke took out a small soft-cover notebook from a pile of miscellaneous items on the desk and flipped through it from back to front...

Not many people bought Laoshuqiang. In the past twenty days, he sold a total of seventy-nine packs.

From these records, he couldn't find Zhengyi Street or Yangguang Community.

Li Ke shook his head at Liu Feng.

Liu Feng took the notebook, flipped through a few pages, pushed it aside, and took out a few photos. "There are several people here. Try to identify them carefully and see who has bought medicine from you."

The peddler muttered, "I'm over 40 years old and my memory is not good. Don't blame me if I make a mistake."

Li Ke put the photos on the small table in front of him, "Take a good look."

The peddler looked at them one by one, "It seems I have never seen any of them before."
