"Dragon Emperor, think about it again! There is a price to pay for going to that place, but the rewards are just as great! That place is very conducive to comprehending the laws of the Heavenly Dao! With your qualifications, you will soon break through the Heavenly Realm! Nangong Zihan looked pity!

"Zihan, don't persuade! Of course I know that, but what I lack most is time! ”

"Hmmm! I believe in the Dragon Emperor! No matter if you enter that place or not, you can advance to the Heavenly Realm! ”

Xiao Chen narrowed his eyes and said, "I vaguely feel that when the day of the thousand-year reincarnation comes, this world will change greatly!" Perhaps, by that time, the age of the end of the law will be over! Xiuzhen will rise again! If you have the chance to enter that place, be sure to search for some ancient and powerful literature. ”

"Hmm!"

Xiao Chen said lightly: "Okay! Getting back to business, we move on to solving the case. At about one o'clock in the morning, there was no one on the construction site, and naturally there were no witnesses. Therefore, the murderer does not need to cover up, he will choose the shortest road to the wall. ”

Nangong Zihan groaned: "There are two real estate projects closest to this footprint, one is the real estate that has just started, and the other one has already been built for the most part. Zhao Qingfan came out at night, and he must have connected with the owner of the smuggled vehicle! Since it is a joint, you should find a more secluded place! The property that has already been built for most of it is easy to hide! So, the building that built most of it is likely to be the scene of the homicide! ”

Xiao Chen shook his head and said, "Zihan, you have ignored a problem!" There was no blood on the body of the deceased! Except for the slap marks on the head, I can't find the slightest scar! Think about it again. ”

"That's right! If the scene of the murder was the building that was most of the building, the deceased would have at least broken his skin when he was knocked down! There are no other wounds on the deceased's body, indicating that the deceased fell to the ground! Nangong Zihan's eyes lit up with excitement, and she felt like she was getting closer and closer to her.

Xiao Chen said slowly: "The deceased's muscles were very relaxed when he died, which means that he did not have any resistance. Moreover, the deceased still had a smile on his face when he died, which shows that he had a good conversation with the murderer! The murderer is a sneak attack! ”

The two talked and talked, and soon arrived at the building where most of it had been built. Seeing the two of them coming over like this, the chubby project supervisor rushed up and asked, "Who are you?" This is a construction site, why don't you wear hard hats? Who's to blame if something happens? ”

"The police are handling the case! Get out of the way! Nangong Zihan coolly showed off his documents.

After carefully looking at the documents, the attitude of the project supervisor has changed a lot, "The construction is heavy, and it is impossible to do it without a safety helmet!" Wait a minute, two police officers, I'll get you two hard hats! ”

Looking at the back of the project supervisor in a hurry, Nangong Zihan squinted his eyes and said, "Dragon Emperor, how do I feel that he has a little problem?" ”

Xiao Chen smiled: "Well, he's trying to find a way to hold us back." I think he won't be able to get this helmet back for a while. However, I'm afraid that the general accident can't help the two of us, right? Let's go. ”

Xiao Chen hesitated for a moment, then raised his legs and walked towards the first unit. Why is it the first unit? Because the first unit is the closest to the gate of the construction site, if you do some shady things, you will definitely find a hidden place as soon as possible.

Xiao Chen and Nangong Zihan walked into the building, and at the same time, the project supervisor dialed Liu Guangming's phone. As soon as the phone was connected, the project supervisor said in a low voice: "Mr. Liu, something is wrong!" Two policemen came to our site! Said it was to handle the case! The matter of hollow steel will not be exposed, right? ”

Liu Guangming was stunned, police? If it's a check of hollow steel, it's good to say! Did they find the clue so quickly? Liu Guangming thinks that he has done this seamlessly! Liu Guangming groaned: "Hurry up and transfer the hollow steel!" Hold those two cops steady for me! ”

"Don't worry, Mr. Liu! I'm dragging them along! I told them to wait where they were, and I went to find them hard hats! Let them wait a little longer! ”

Liu Guangming was furious: "Liu Meng! Are you a pig? Are they, the police, afraid of death? Are you afraid of some accidents? Hurry up and send them the hard hats! Don't leave a single step! I can feel the construction site in ten minutes! ”

"Yes! Be! Be! Liu Meng hurriedly answered.

As soon as he entered the building, Nangong Zihan frowned invisibly! What does this smell like! Many migrant workers are convenient, and their urine and urine are solved here. Nangong Zihan hurriedly stepped on the stairs.

After going up to the second floor, the air smelled much better. Xiao Chen said with a smile: "Zihan, there are too many comfortable days, can't stand such a little smell?" What if the first floor is the scene of the conversation between the two? ”

Nangong Zihan knew that Xiao Chen was studying him, and puffed out his mouth and said, "Dragon Emperor! Don't be funny! Zhao Qingfan is the deputy director of customs, and his quality of life must be very high! He definitely wouldn't talk to people in that kind of environment on the first floor! Zhao Qingfan called Zhao Yuanyuan at twenty-two o'clock last night! He died at one o'clock in the morning today! This shows that Zhao Qingfan and the murderer chatted together for three hours! So, I conclude! The place where the two of them chatted was definitely not on the first floor! ”

Pap, papa, pap, Xiao Chen clapped his hands gently, obviously he was very satisfied with Nangong Zihan's analysis.

Xiao Chen said lightly: "Zihan, you analyzed it well!" It is very likely that Zhao Qingfan and the murderer chatted for a long time on the second floor! There are so many rooms on the second floor, can you find a room for two people to chat? ”

"Dragon Emperor, what's the use of finding a room where the two of them are chatting?" Nangong Zihan looked puzzled.

"Details! Pay attention to the details! Zhao Qingfan's right fingernail is a little yellow, indicating that he has a long smoking age! Since he is a long-smoker, who has been talking for three hours, he must have smoked, right? ”

"yes, but what does that mean?" Nangong Zihan still didn't understand Xiao Chen's intentions.

Xiao Chen said lightly: "Also, it's normal for you girls who don't smoke to think of it." Men smoke when they smoke. If the assailant also smokes, then his saliva will remain on the cigarette butt! In this way, it is much easier to identify the murderer. ”

"Got it! I'm going to find a room with cigarette butts right now! ”

Two minutes later, Xiao Chen and Nangong Zihan found a large number of cigarette butts in the three rooms. It can be seen that there are people in these three rooms who often get together to smoke! Nangong Zihan shrugged his head and said, "Dragon Emperor, with so many cigarette butts, this target is too big!" ”

Xiao Chen chuckled; "You can narrow down your goals!"

Nangong Zihan blinked, and after thinking about it for a long time, he didn't come up with a reason, Nangong Zihan said nonchalantly: "Dragon Emperor!" Don't sell it, okay? You're going to kill me! How do you shrink it? ”

Xiao Chen said lightly: "Zihan, if you don't count Zhao Qingfan and the murderer, there are two kinds of people who smoke here. The first type is ordinary migrant workers, who smoke the least cigarettes. The second type is the middle-level leaders of the construction site, who smoke a slightly higher grade! ”

Nangong Zihan's eyes lit up, and he said in surprise: "I understand!" The cigarette butts of 203 are all inferior cigarettes of less than 10 yuan, which shows that 203 is a gathering place for migrant workers. The cigarette butts of 207 are a little more high-end, almost a dozen to 20 cigarettes, which shows that 207 is a gathering place for middle-level leaders on the construction site. And the cigarette butts of 218 are soft China! Therefore, 218 is the place where Zhao Qingfan talks to the murderer! ”

Xiao Chen smiled: "All right! ”

Xiao Chen and Nangong Zihan walked into 218 and found a pile of cigarette butts by the window of the master bedroom. The pile of cigarette butts is new and apparently freshly baked. The corners of Xiao Chen's mouth turned up slightly, it seems that the murderer is still careless! Judging by the number of cigarette butts, this is definitely not the number that one person smokes in three hours!

"Zihan, put these cigarette butts away, take them back and let Mengrou extract the DNA, and then compare them with the NDA library."

"Yes!"

Nangong Zihan walked to the cigarette butt pile and squatted down, and took out a white glove from his pocket, a transparent plastic bag with a seal. After putting on the white gloves, Nangong Zihan picked up the cigarette butts on the ground one by one and threw them into a sealed plastic bag.

Liu Meng carried two hard hats and rushed out of the office in a hurry. These two cops aren't really afraid of death, are they? Liu Meng was stunned! Where is there anyone in the position just now? What to do? Hollow steel won't be exposed, right?

Liu Meng pulled out his legs and ran to the warehouse! At this moment, Xiao Chen and Nangong Zihan walked out of the cave of the first unit building. Nangong Zihan asked with a smile: "Supervisor Liu, what are you doing in such a hurry?" ”

Ga? Didn't go to the storeroom? It's good that I didn't go to the storeroom! Liu Meng hurriedly stopped and sneered: "Aren't I worried about the safety of the two police officers?" Oh, the helmet has been brought to you! It's too dangerous not to wear a helmet on a construction site! ”

Xiao Chen took the helmet and said lightly: "Okay, you also sent the helmet, you can play by yourself!" ”

Liu Meng hurriedly shook his head and said, "How can this be done?" Two to handle the case, as the construction site supervisor, I must help the two! Where are you going? I'll be a guide for both of them! ”

Xiao Chen ignored Liu Meng, looked around, and then walked towards the building that had just been built, because Xiao Chen saw a pile of yellow sand between the two buildings! This shows that Zhao Qingfan is very likely to take this route.

Seeing that Xiao Chen didn't speak, Liu Meng followed Xiao Chen in a sneer, as long as Xiao Chen didn't go to the warehouse! Liu Meng made up his mind that he would never make any hollow steel in the future! It's too worrying to be a thief!

When passing by the yellow sand pile, Xiao Chen did not stop. It wasn't until he walked next to a blender that Xiao Chen stopped. Xiao Chen found a few shovels next to the mixer! Xiao Chen picked up a shovel and kept looking at it.

Nangong Zihan asked curiously, "These shovels are stained with sand and lime, shouldn't they?" ”

"These limes and sand are the best umbrellas!"

Xiao Chen was unmoved, and picked up several shovels in a row. Suddenly, Xiao Chen squinted, and he handed the shovel in his hand to Nangong Zihan.

"Look at this shovel."
