A ray of sunshine shone on Liu Pengcheng's face, and he definitely couldn't sleep now.

Liu Pengcheng struggled to get up and was about to look at the pager next to the pillow, when he heard Achai's voice next to him: "At half past eleven, you get up now and take me to eat something special and delicious,"

The two of them went to the hotel to rest after Professor Park's operation. This is the hotel of the Public Security Cadre School, which was also arranged by Principal Ding.

Professor Park is out of danger for the time being, but there is a second operation in three days. This surgery is the real key, and it is said that it is possible that you may not be able to get off the operating table, but if you want to wake up, this surgery must be done.

Liu Pengcheng saw a black plastic bag on his bedside table and asked, "What is this?" ”

Achai shook the Ericsson 398 in his hand and said, "This is it." I went out for morning exercise in the morning, and I saw on campus that people from the telecommunications bureau were organizing a group purchase of teachers from your school, so I bought two, don't say it, such a small big brother, the signal is really good. ”

In Liu Pengcheng's mind, this mobile phone is a milestone, the first "mobile phone that looks like a mobile phone".

Liu Pengcheng also opened the black plastic bag, revealing the packaging of Ericsson 398, and asked, "How much?" ”

Achai said: "It's not much, it's only 7200, it's cheap!" ”

Liu Pengcheng wants to say that if 7,200 yuan can buy a Snapdragon 888, a folding screen, a 5G signal, and a mobile phone with a 100 million pixel camera, it will be cheap.

But it is estimated that Achai can't understand it, but suddenly in the middle of the big brother of more than 10,000 units, such a small thing full of science and technology for thousands of yuan should indeed be cheap.

Liu Pengcheng asked, "Is there any news?" ”

Achai shook his head: "No, I'm only an hour and a half more awake than you." An hour of morning exercise plus buying these two phones, and then woke up half an hour earlier than you. ”

Liu Pengcheng washed in the bathroom, brushing his teeth and said vaguely: "I'll give you the phone money later." ”

Ah Chai was already wearing his coat, and said nonchalantly: "It's okay, these two money won't delay anything, just give it when it's convenient." ”

After Liu Pengcheng finished washing, he called the fourth child first, and learned that Professor Park was still in a coma, and told Liu Pengcheng not to come to the hospital in a hurry.

Liu Pengcheng listened to this, the fourth child should still be in the hospital, he said that there was nothing wrong, so it would be okay to go again after a while.

Liu Pengcheng took Ah Chai downstairs.

He's too familiar with this place, alma mater. Liu Pengcheng thought about Guess's appetite that seemed to be digestible for anything, and decided to take him to eat the most representative delicacy in Shencheng.

So, twenty minutes later, Ah Chai looked at the chicken rack and chicken soup noodles in front of him, and his eyes straightened: "The people in this place are so good at doing business, they use chicken bones to make soup and sell it to me, and then boil the bones used for soup and sell it to me." ”

Liu Pengcheng wanted to refute, but he really didn't know what to say, and what Achai said seemed to make sense! So he rewarded Achai with a bottle of Hachiwangji soda.

When Achai started eating, he didn't have any reason. The chicken rack was gnawed so clean by him that he almost chewed the bone. In the end, he drank all the noodle soup. But the reaction to the Hachioji soda was average, and I felt that making the soda so "spicy" was simply anti-human.

In short, the two of them walked out of the old four seasons with a full burp.

Liu Pengcheng's pager rang, and this time he picked up his phone and started calling back.

It was the phone call from the senior brother, asking Liu Pengcheng if he had eaten, and if he hadn't eaten, he could invite him to dinner.

Liu Pengcheng hurriedly said that they had finished eating, and it was the old four seasons outside the school.

It may be that the place to eat is too down-to-earth, but the senior brother reacted after a while, and continued to say that you will go to the scene after eating, and I will wait for you at the scene.

The scene is Professor Park's home, and Liu Pengcheng is familiar with this place, and it is only a few minutes away from driving.

When I went to the scene, there was no longer any meaning of the scene, as if nothing had happened.

The senior brother took out a piece of paper and handed it to Liu Pengcheng: "Let's take a look at it yourself." ”

This is a hand-drawn floor plan of the site.

Liu Pengcheng and Achai quickly reconstructed the crime scene in their minds.

It's actually quite simple.

The floor plan recorded the time at 11:45 p.m. last night.

In fact, at that time, Professor Park had already been taken to the hospital. The police also drew the picture based on the eyewitnesses at the scene, the description of the police who arrived first, and some traces of the scene.

Professor Park was lying on the ground, less than three meters away from the security door of her unit. Holding a bunch of keys in his hand, and pinching one of them with his right index finger and thumb, it should be the key to the unit door.

But on the picture, there is no graphic of Professor Park's bag, that is, Professor Park's bag is not seen at the scene.

Liu Pengcheng asked, "Senior brother, is there any progress in the case?" ”

The senior brother thought for a while and said, "The case has been merged, and now almost all the police in the city are handling this case." ”

Liu Pengcheng was just about to ask what was going on, but the senior brother asked first: "Liu Pengcheng, do you know the planing adze?" ”

This is also the biggest conjecture in Liu Pengcheng's heart, he nodded: "I know, are you sure?" ”

The senior brother said: "It is confirmed, this morning the Technical Department of the Provincial Department made a plaster cast of the murder weapon based on the wound on the back of Professor Park's head, which is a planing adze. ”

Liu Pengcheng suddenly asked, "Were there any other robbery cases last night?" ”

The senior brother shook his head: "No, at least the police have not received a report. ”

Liu Pengcheng continued to ask: "How many." ”

Senior Brother shook his head: "We have already caught four criminals. Each of them committed several crimes. However, the main culprit has not been caught, and according to our trace analysis and the description of the surviving victims, there are at least 23 more cases, which were committed by the same person and have not been solved. ”

Liu Pengcheng asked, "Are there any who haven't been saved?" ”

The senior brother nodded: "Yes, five." ”

Liu Pengcheng looked at Ah Chai confused and said; "Planing adzes are a tool that is used by carpenters and bricklayers in the Northeast. In fact, it is a kind of hammer, with a normal hammer on one side and a sharp blade in the shape of a duckbill on the other.

Recently, many cities in Northeast China have seen robberies with shovels as murder weapons. This thing is small, very easy to carry or hide, after finding the target, follow the target, wait until it is in a remote place, hit the back of the head with a planing adze, the victim will fall to the ground at that time, lose the ability to resist. ”

Liu Pengcheng found a clean sandy area on the ground. I used the mobile phone antenna to roughly draw the appearance of the roots.

Ah Chai looked at the simple planing diagram and nodded, indicating that he understood.

Liu Pengcheng asked Senior Brother: "Senior Brother, let's talk about something directly." You're not just here to see the scene. ”

Senior Brother nodded and said, "Okay, I'll just say it." The bureau has asked the Ministry of Public Security for help and support to crack the series of robberies as soon as possible. The ministry has sent a Paladin team, and can be assisted by the Listening Pavilion when needed. ”

Liu Pengcheng remembered what Lao Zhou said when he set off from Ruicheng, it seems that he has long known about this case, but he didn't expect that Professor Park's case and the planing case were mixed together.

The elder brother continued: "If possible, I would like to take my brothers with me to assist you in your work. ”
