The big water truck, the bar street, the alley where Xiao Su was killed.

Xu Jingnan had been here for a whole day. He seemed to have nothing to think about, but just kept walking, walking from one end to the other, and walking back from the other end.

He really didn't think about anything, he had thought about what he should have thought about a long time ago. What he lacked now is inspiration, and too preconceived judgments will affect the emergence of inspiration.

Xu Jingnan exercises his body by the way. Since becoming a forensic doctor, he has rarely had the opportunity to exercise. He is too busy with work, so many people will definitely ask, no matter how busy he is, he has time to run or something, right?

Yes, it can still be squeezed out for half an hour in time, but it’s irregular!

The life that cannot be planned is full of too many variables, so he took advantage of this opportunity to just run, so his thinking was obviously much more active.

The inspiration has not appeared for a long time, and he is not in a hurry.

The path was not just chosen in a single way. He ran along the main street to the northeast, then turned into any alley based on his mood, circled around and ran back in the opposite direction, occasionally stopping at the door of a certain bar. He went to the toilet more than a dozen times that day, and everything was heard from his body's natural reaction.

He intends to keep this state until two or three in the morning to complete a nearly 24-hour cycle.

This may also be the activity trajectory of Xiao Su, some tourists, men and women, love prodigal sons, band singers, and even criminals for one day.

It was the twelfth time that Xu Jingnan had passed by Nuoqing Bar when the lights first came on. This was his focus. As for what he paid attention to, he didn't know what he paid attention to, and there was no need to figure it out.

Everything follows the feeling!

He wore a pair of sports headphones and played two songs in a loop: "Follow the Feeling" and "The Rest of Your Life".

Xu Jingnan was wearing sportswear and headphones, bent over and put his hands on his knees, gasping slightly. He stood not too far from Nuoqing Bar, observing the people coming in and out. This angle happened to be the direction of Xiao Su's eyes at that time - why did he look here? Is there any special significance?

Maybe there is nothing, it's just a direction I chose by chance before dying.

It has been a long time since he did such a meaningless thing. To be more precise, he has not been so far away from science, common sense, common sense, and so boring.

Who asked the fourth brother to arrange such a task? He said in his heart that this is contrary to the forensic profession, and he actually started to do hard-core reasoning again.

The bureau's unwritten regulations mean that forensic doctors do not have to participate in criminal investigations. At this time, he is more like Boone You's ignorant little policeman, and more like a boy who still has longing and fantasy.

I have to say that Xu Jingnan likes this feeling, hey, I haven’t seen each other for a long time, I’ll meet again after a long time separation!

Since he studied majors and gradually deepened, he has inexplicably rejected reasoning in a subtle way. This may be an occupational disease, or it may be that he has recognized the facts - the corpse will tell you the truth, and he will never lie, but reasoning is actually useless.

How many people in the police station use reasoning to solve cases? They can adjust surveillance, investigate and visit, squatting, record confessions, and autopsy. What they can know is basically clear, and the reasoning that they cannot know is in vain.

What era is now, and he still uses reasoning? He thought it was ridiculous.

Over time, the only discomfort may be that my brain is a little dull or a little numb.

He gasped and thought about these things.

Brain cells seemed to be slowly resurrecting without realizing it, and their eyes began to illuminate.

--------------------------------------------------------------------

My stomach rumbling.

Xu Jingnan knew that this was not hunger, but stomach discomfort. If you didn’t do high-intensity exercise for a long time, the first thing that caused discomfort was of course the most fragile abdomen.

He smiled bitterly, turned around and walked towards the alley not far away, where there was a bathroom. When he walked into the entrance of the alley, there were people entering and leaving the alley, and his steps were rushing, as if someone was waiting for him somewhere, and he couldn't wait to solve his physiological problems. Of course, it was a temptation for women.

Xu Jingnan smiled secretly. Isn’t the most primitive desire in the world just toilets and bars? It meets all the needs of men and women, and the distance is just a short distance.

He squatted in a grid and inexplicably thought of such a simple and simple truth.

He has taken turns squatting all the six grids here today.

For nothing else, I just want to do this, maybe I am amused by the landscape in the grid.

There are many numbers written on the walls on both sides of the grid, almost all of which are 11 digits. There are drawings and writing on the sides. They are nothing more than the shape of certain human organs, or: same-sex, do you have a date? Long legs and big eyes, wait for you. J, brother, come on.

The small paper advertisements are all over the place, with a bit of a graffiti wall.

Xu Jingnan glanced over these words, and for some reason he felt a little laughing. As a forensic doctor who dissected the human body all day long, he didn't know what the attraction was.

About half an hour later, Xu Jingnan, who was distracted, remembered to get up, but when he stood up, his head suddenly felt dizzy and his steps staggered a few times. He subconsciously held the lattice cement wall. What a guy, his legs were numb.

He suddenly had nothing to buy, and he was surprised and realized that a small piece of cement he bought had fallen off.

He smiled bitterly: This quality.

The cement blocks less than the size of a fist fell on the flat ground made of rough cement, making a crisp sound, shattering into several small pieces, and the impact part turned into powder.

This crisp sound suddenly touched a certain nerve of Xu Jingnan.

He squatted down and picked up the cement blocks on the ground again, regardless of whether it was dirty or not. What he touched every day was not as dirty as this?

If someone sees what he is playing, he will definitely think that the person is mentally ill or has psychological problems.

Xu Jingnan stroked the cement block in his hand without anyone else, and pinched it hard, without any feeling of being shaken, but why did it fall off just now just by just touching it lightly?

Did it have cracks a long time ago? It just took some time to fall by chance?

Why don’t several other places fall, but this one falls?

This is actually not logical. From a scientific point of view, it is really too sensitive. It is entirely possible that there are many loose parts in this bathroom. After all, you can tell at a glance that this is a long-standing building, with spider webs all over the walls, and there are cracks on the walls.

In view of this judgment, Xu Jingnan began his "search journey" in the toilet.

He wanted to prove that there were no cement blocks that could be dropped in other parts here. This was really a huge project, but Xu Jingnan did not give up on this idea.

He had a premonition that he was about to find a key node!

During this period, three or two people entered the toilet and just glanced at him. Xu Jingnan stopped searching and quietly waited for these people to leave. These people obviously had no idea and left in a hurry.

There were only a few people who were squatting in large size, which made Xu Jingnan a little impatient, but he still held it back.

At this time, he actually found a pit and squatted up again. After a few times, even he couldn't help laughing. What's this? But since he had made up his mind, he didn't care about this anymore.

After going back and forth, Xu Jingnan's conclusion was almost coming out: there should be only such a little special in the entire toilet, and he happened to be caught by him.

As we all know, although some ordinary toilets are simply mixed with cement and sand and do not require too many processes and modifications, this kind of toilet is the most durable and sturdy. On the contrary, those with beautiful tiles and surfaces covered with putty and fine cement are easy to fall off.

In other words, the only explanation for the reason why this piece of cement fell is that it has been hit by external forces!

That's right, it's just impact, otherwise it's impossible to cause damage to the internal structure.

It's really magical. This is the role of time and reveals special flaws.

Xu Jingnan stood there for a long time when he was squatting just now. His eyes started from the damaged part and slowly raised it up. He soon discovered an invisible track. This arcuate track, along the damaged part, was about 60 degrees slanted up, connecting the entire toilet's vent - a 50cm square window.
