From the afternoon to the evening, Xie Qing watched all the videos that Shen Yi left in the safe, but she didn't find anything unusual.

Shen Yi went to the toilet four times in total, once with Gu Ling and three times alone. He walked steadily, didn't say hello to anyone, and didn't have any physical contact.

Xie Qing turned off the projector, packed up her things, and went out with her schoolbag.

Huang Zhenyi was making tea with boiling water. He smiled and asked Xie Qing: "Xiao Xie, did you find anything?"

From the tone of her voice, Huang Zhenyi obviously knew what she was doing.

Xie Qing shook her head regretfully, "No."

Huang Zhenyi said: "Ren Yaguang took the tape home to watch it. He called to report during dinner that there was nothing unusual about Shen Yi in the safe."

This seemed a bit like a waste of effort.

Xie Qing smiled embarrassedly, "Maybe I think too much."

Huang Zhenyi said, "In our line of work, it's a good thing to think more, but we're afraid of not thinking enough. Your eyes are red from staying up all night, hurry back and have an early rest."

"Okay, goodbye, Captain Huang." Xie Qing walked out, and just as she reached the door, the shrill phone rang, "Ding-ling-ling, ding-ling-ling..."

Huang Zhenyi had already gone into the back room and ordered, "Xiao Xie, answer it for me." "

Okay." Xie Qing agreed and quickly picked up the receiver, "Hello, Second Brigade of the Municipal Bureau."

"Qingqing?" Li Ke's excited voice came from the other end of the phone, "Qingqing, let me tell you, we just saw Fan Xiaoshan. He smoked a cigarette on the dam and took a long time to leave."

Xie Qing raised her voice, "Where are you now, where did Fan Xiaoshan go?"

Li Ke said, "We are near the sewage treatment plant. He left five minutes ago and went towards the Wangjiang community. Is Captain Huang here? Please report the situation for me."

Huang Zhenyi came out, "Who's calling and what's the situation?"

Xie Qing briefly introduced the situation.

Huang Zhenyi stroked the hard stubble on his chin and

said, "Let them come back first." Xie Qing said, "Keke, you heard me, right?"

Li Ke said, "Got it, I'll be right back."

When Xie Qing put down the receiver, Huang Zhenyi was still in deep thought. She looked around and saw that except for a few criminal police officers on duty, no one else was there.

So, should she leave?

Xie Qing pondered for a moment and finally stayed - Fan Xiaoshan's appearance on the embankment did not prove that he was a criminal suspect, and Li Ke and Li Ji might not be able to convince Captain Huang. Since it was her idea, she should stay to show her support.

About two or three minutes later, Huang Zhenyi sent a pager to Fu Da, the leader of Group 1, and told him to organize the team members to come to the office immediately.

Xie Qing breathed a sigh of relief. That's good. Huang Zhenyi accepted it.

Huang Zhenyi said, "Xiao Xie, you three guys may have done something great."

Xie Qing said modestly, "Captain Huang, it's only good if we catch the talent."

Several criminal police on duty also gathered around, "Captain, is there any progress in Huang Qi's case?"

"I think so." Huang Zhenyi pulled out a folder from Li Ji's desk, found Fan Xiaoshan's information in it, and quickly read it through.

An old criminal police glanced at Xie Qing, "Captain Huang, do you have any evidence?"

Huang Zhenyi said, "When everyone is here, we will go find it."

Xie Qing was completely relieved and walked out quietly.

"Xiao Xie." Huang Zhenyi called her, "Tomorrow is Sunday, you can sleep in, no need to rush, you can come with us."

Xie Qing quickly refused: "No, no, I'm tired after watching the video all afternoon, I have to go back to sleep."

Huang Zhenyi said: "If we find the bricks, we will still need your forensic doctor and technical room, let's go."

This is true.

Xie Qing agreed.

“If this works, the burden on my shoulders will be half lightened.” Huang Zhenyi rested his butt on the desk. “The previous victims’ families came to the police station many times, and I felt sorry for them every time. Now there’s the Huang family. Although they are my relatives, I have to say that this family is too powerful. My head is about to explode because of their noise. If we can solve the case, I will take credit for you and treat you to delicious food, hahaha…”

Several criminal police on duty showed expressions of disbelief on their faces.

A criminal policeman said, "Captain, these guys are really lucky."

Another one also said, "That's right. There were so many drivers of red Xiali cars, but it was not easy for these three guys to hit the target with one shot!"

Huang Zhenyi smiled slightly, "It's not wrong to say that they are lucky. Xiao Xie's reasoning is called psychological profiling in foreign countries, which is specifically aimed at serial killers. It has certain scientific basis, but most of the predictions are inaccurate. Our country has few applications, but the United States has more research and applications in this area, right, Xiao Xie."

Huang Zhenyi is a veteran, but he has a comprehensive grasp of criminal investigation knowledge.

Xie Qing nodded in admiration, "That's true."

Huang Zhenyi said, "Luck is also a part of strength. Xiao Xie is a lucky general of our Second Brigade."

Xie Qing said, "Captain Huang, you deserve the award."

...

About half an hour later, a group of members arrived.

Fu Da was thirty-seven or thirty-eight years old, in the prime of life, and full of energy. As soon as he entered the room, he asked, "Captain, do you have any clues?"

Huang Zhenyi stood up, "We have clues. We will rush to Wangjiang Community and set up control at various traffic arteries. Once we find Yan C7569, report to me immediately."

Several members of the first group looked at each other, and only Li Ji and Li Ke understood that it was Fan Xiaoshan's license plate number.

Du Zhun was a chatterbox. "Captain, whose car is this? What should we do after we find it?"

Huang Zhenyi said, "This is the car of taxi driver Fan Xiaoshan. He is a major suspect in the murder of Huang Qi. After you find the car, you must not act rashly. I will conduct a spot check on it."

"Oh..." Fu Da understood. Not attacking head-on meant that he had not yet obtained definite evidence. To put it more concretely, the next action was crucial. Once it failed, all evidence might be lost.

Huang Zhenyi looked at Fu Da, "Do you understand? Tell us in detail and we'll set off after you finish."

"Yes." Fu Da stood at attention and implemented the next arrangements in detail.

...

Ten minutes later, Huang Zhenyi took Xie Qing, Li Ke, and Li Ji to a black Santana and drove towards Linjiang Road.

The car stopped at Jian'an Road near Wangjiang Community.

Li Ke yawned and asked Xie Qing, "

How long do you think we have to wait?" Huang Zhenyi said, "It's hard to say. If you are tired, take a nap. I will watch you."

"How can I do that?" Li Ke said with a tough mouth but honest body. She yawned slightly and leaned back in the chair.

Xie Qing said, "Thank you, Captain. I am really sleepy. I will take a nap." It's better to take a nap than to have an awkward chat.

Huang Zhenyi said, "Go to sleep, I..."

"Is that the car?" Li Ji straightened up, leaned over the steering wheel and stared straight ahead, "Yan C7569, it's him, it's him!"

Li Ke jumped up all of a sudden, "Where is it?"

"Don't get excited." Xie Qing held her down, "He just passed by and went to the gate of Wangjiang Community."

Huang Zhenyi picked up the car walkie-talkie, "Fu Da, the suspect passed by me and will show up at your place soon."

Fu Da's voice came from the walkie-talkie, "Got it, and must pay close attention." Three minutes later, he reported again, "I saw it, I saw it, he went to Jinyang Road, and his speed was slow."

"Got it." Huang Zhenyi called Du Zhun, "Immediately set up a temporary inspection point at the intersection of Jinyang Road and Fuyang Commercial Street, I'll be there right away."

Du Zhun replied, "Got it."

Huang Zhenyi told Li Ji, "Let's go, turn from the front street."

...

Three or five minutes later, the car arrived at the intersection where Du Zhun was.

Du Zhun had already put up a large sign for temporary inspection, and several criminal police officers had stopped two private cars and were questioning them.

Li Ji and Li Ke got off, and Xie Qing did not move for the time being.

Huang Zhenyi called Fu Da, "Are you catching up?"

Fu Da said, "We'll be there soon."

"Xie, don't be in a hurry to get off." Huang Zhenyi closed the car door and stood on the side of the road with his bag under his arm.

Fan Xiaoshan's car arrived, and Du Zhun stopped him smoothly.

The two men exchanged a few words and Fan Xiaoshan got out of the car. He was a handsome and gentle young man with a long face, red eyes and thin lips. He was a bit more handsome than Li Ji. He was of medium build. Although he was not burly, he was definitely not thin.

Fan Xiaoshan took out a pack of cigarettes from his pocket and handed it to Du Jun, "It's so late and you're still conducting a surprise inspection. You've worked hard."

"The leader is watching us. I dare not accept it." Du Jun pushed the cigarette box away and opened the car door. "Are there any prohibited items in the car?"

Fan Xiaoshan smiled and said, "We are legitimate taxi drivers. We drive day and night. Why would we deal with prohibited items? There's something big happening in the city recently. Why are there still surprise inspections?"

Du Jun rummaged around in the car. "Aren't you guys well-informed in this line of work?"

Fan Xiaoshan said, "Are you talking about the incident on Jinhua Road?"

Du Jun stepped out of the car and looked back at Huang Zhenyi.

Huang Zhenyi walked over, "Open the trunk."

Fan Xiaoshan hesitated, "Leader, we are just driving a taxi, there is really nothing in the car."

Huang Zhenyi smiled slightly, "You dare not open it, are you guilty?"

"Absolutely not, absolutely not." Fan Xiaoshan waved his hands repeatedly, "It's just that there are a lot of things in the trunk, I'll open it now, open it now."

He took the key and opened the trunk.

There were indeed a lot of things in the trunk, a bag of clothes, a pair of sports shoes that were brushed clean, a car repair tool box, a small broom, a rag, etc.

But there were no bricks!

Fan Xiaoshan stood aside, observing Huang Zhenyi inconspicuously, with a look of neither servility nor arrogance, and no hurry.

Huang Zhenyi opened the tool box, and the tools were neatly arranged, which was clear at a glance.

Du Jun checked the bag of clothes, but also found nothing.

Li Ji and Li Ke looked at each other anxiously.

Fan Xiaoshan said, "Do you want to see more, leader?"

Huang Zhenyi stood in front of the trunk, a little hesitant, "You are a taxi driver, why do you carry clothes and shoes?"

Fan Xiaoshan said, "I don't know when I started driving long distances, so I'm prepared." His right hand climbed up the trunk lid and prepared to push

it down. Huang Zhenyi wanted to stop it, but he didn't know how to stop it, so he had to watch it fall.

At this time, Xie Qing arrived, she opened the back door, fumbled around the chair, and put the backrest down.

Fan Xiaoshan suddenly became anxious, "Hey, who are you? What are you doing! Don't touch my car."

Huang Zhenyi moved his foot and stopped him, "It's a temporary inspection, of course we have to check it carefully."

Fan Xiaoshan's face turned pale and he took a step back. Du Zhun stood behind him, blocking his way.

Xie Qing lay on the back seat for a while, and found a yellow brick between the seat and the trunk. With the help of the street light, he could clearly see a large piece of black stain on the brick. "Captain Huang, I found it. I'll take it back to the technical room for testing."

Fan Xiaoshan's face was ashen, his eyes were dull, and his feet staggered.

Du Zhun grabbed his wrist and handcuffed him with a click. "Fan Xiaoshan, we suspect you are involved in several murders. Come with us."

...

After testing, the blood on the bricks did belong to several victims, including Huang Qi, Gu Decheng, Yan Lifen, Gu Daqiang, etc.

Fan Xiaoshan did not deny it and confessed that he not only killed the above people, but also killed three homeless people with impaired IQs.

Interrogation room.

Huang Zhenyi: "Why do you kill people?"

Fan Xiaoshan: "I only kill bad people. This is the ambition I set when I was a child, and I have achieved it. Let me tell you, I am different from my mother and sister. I am a good person, a person with ideals."

Huang Zhenyi: "Good people and bad people, the law has the final say, not you."

Fan Xiaoshan: "This leader, you can't deny that there are bad people in this world who cannot be severely punished by the law. Isn't it good to have people like me to enforce justice?"

Huang Zhenyi: "Of course it's not good. You trampled on the law and violated the rights of the victims. In essence, there is no difference between you and them. Besides, you sacrificed your life for someone who had nothing to do with you and made your child orphan at a young age. What's good about this? Tell me, what's good about this?"

Fan Xiaoshan slammed the table and shouted like crazy: "If you bastards hadn't arrested me, how could I die and how could my child be orphaned? It's all your fault, all your fault, wuwuwu..."
