The smell came from the rot formed by some garbage.

Unlike a normal reservoir, there are a large number of fish, shrimp, algae, and various microorganisms present. In such a coal mine seepage tunnel, there are very few living things, and they are particularly single.

Occasionally, there are fish and other things, but they are barely alive, and it is more difficult to form an ecological system like a reservoir.

The garbage dumped in it decomposes very slowly.

When the large machinery started working, some of the exposed rot began to emit a smell under the sun.

The faces of the leaders of the mining bureau looked even worse.

Landfilling of garbage is not prohibited, but there are certain rules. Like the Unity Coal Mine at the foot of the mountain, because it is a shallow open-pit coal mine, it was quickly depleted after being jointly established by several communes, and the exposed mining area eventually became the landfill site of Zifeng Town.

That was an approved landfill site, and they had to pay and take responsibility, and also waterproof the bottom.

The requirements for landfilling in this area are much stricter, and not all household garbage can be dumped in it.

The mining bureau's violation of regulations will definitely cause trouble in the future...

Xu Taining and the others couldn't manage all of this, they just stretched their necks and waited for the large machinery to move some of the upper concrete, then ordered, "Forensic first. Wait for the police dog."

The feet of police dogs are very delicate, and if there are too many broken concrete bricks, cables, and steel bars underneath, it is easy to get injured.

The forensic doesn't matter.

Jiang Yuan didn't say a word, dressed neatly, and descended from the side of the rock wall in a basket.

There are many such things in the mining bureau's warehouse, but they have been neglected for a long time, and it is unknown whether they will kill someone.

A mine shaft about 50 meters deep is equivalent to the height of a 13-story building. Looking down from above, it is still a bit terrifying.

Of course, the terror index at the bottom of the pit is even higher. The slimy mud, sticky feeling underfoot, occasional steel bars, iron wires, abandoned equipment, coal...

There are also various huge concrete blocks standing around, and it is unknown whether they are stable or not.

"I hate dealing with this kind of scene. I haven't seen the body yet. Shouldn't the forensic team come first?" Forensic Wang Lan, who was wrapped tightly, was already grumbling.

Jiang Yuan had already greeted her just now, as well as the other forensic next to her, who had all come to support today.

The case happened in Qinghe Town. Although the provincial department sent many people to support, the main force was still the local police in Qinghe City.

Several forensic experts checked each other's equipment and began to get busy.

Complaints aside, Wang Lan did not drag her feet, first cautiously stepping on the ground that could be stepped on, then gradually expanding the scope of the investigation, and inserting flags in the deeper areas that needed to be examined by hand.

In no time, the legs of several people were stuck in the mud to the point where they couldn't move. The thighs of the tall and disadvantageous forensic were buried, making it even more difficult.

"Do you want to use a machine to dig?" Wang Lan moved to the side of the forensic.

The forensic hesitated for a moment and said, "Forget it, I smell something off."

"Is it a bit of a smell of a corpse?" Wang Lan confirmed with the forensic.

"I feel like it is." The forensic took off the mask and took a few sniffs, nodding in affirmation.

For forensic experts, the sense of smell itself is a very important judgment criterion. For example, if the smell of a corpse is mixed with a sweet and greasy taste, it is necessary to consider poisoning among the deceased.

However, because it is difficult to express the sense of smell in movies and TV shows, and ordinary people are afraid of the smell of a corpse, there are few descriptions of the smell.

In reality, humans are born with a sensitivity to the smell of a corpse.

The biggest obstacle to dumping a body is also the smell.

Many people die at home, or are dumped on the side of the road, and the most easily discovered reason is the smell.

The underwater mud originally had no smell, but under the scorching sun, it gradually emitted various smells.

Jiang Yuan and the other two young forensic experts were wearing activated carbon masks, filtering out most of the smell. They listened to the conversation between Forensic Wang and Forensic Niu, and did not have the intention to specifically sniff.

Jiang Yuan has LV4 crime scene investigation, so for him, he can observe more information.

As for the other bonuses brought by the smell, they can be completely achieved by other means.

For example... the sense of touch.

Jiang Yuan bent down, reached out, and slowly pulled out an... arm.

At times like this, crime scene investigation can always produce some special investigative effects.

"It's human." Jiang Yuan took a look and shouted.

This time, not only the forensic experts at the bottom of the cave, but also the crowd above the cave, were in a commotion.

"Confirmed human remains." Wang Lan hurried over to take a look and gave an affirmative answer.

Having human remains is not a good thing, but at least it proves that this long and arduous operation is not a joke.

The white-shirted people at the top also breathed a sigh of relief.Xu Taining immediately took out his phone and started making a call.

Although thousands of people had been mobilized, consuming a vast amount of manpower and resources, solving a murder case was still considered justifiable.

Of course, finding Liu Jinghui alive was very important, if he was still alive.

Xu Taining whispered to the person next to him, and then someone used a walkie-talkie to ask, "How long has the body been dead? Does it exceed a week?"

This was a discreet way of inquiring whether it was Liu Jinghui or not.

Wang Lan nudged the walkie-talkie and said, "There's adipocere, it's at least a 10-month-old corpse."

Adipocere is a relatively rare phenomenon in corpses, generally only forming in water or in moist soil, where the body's fat undergoes saponification.

A body with adipocere is called a preserved corpse. Similar well-known examples include mummies, like the Egyptian mummies or the Loulan mummy.

The conditions for forming a preserved corpse are quite stringent and take a long time. But once formed, they can be preserved for a much longer period. Just like the mummies and the Loulan mummy, they have a history of thousands of years and have not decayed or skeletonized like traditional corpses.

However, determining the exact time is another complex task.

Knowing that the body was not Liu Jinghui's, Xu Taining said, "Continue the search."

Then, he discussed further with several white-shirted superiors.

The atmosphere around the mine shaft noticeably improved.

This was most clearly felt by the police dogs; both Heizi and Strong sat down obediently, showing no signs of restlessness, like calm town civil servants.

More technicians were lowered into the pit in baskets.

Those who usually sat in offices now had to stoop down and dig through the mud.

Everyone gathered around the spot where Jiang Yuan had found the arm and began to expand the search downwards.

Now there was no need to grope around; in the knee-deep silt, everyone used an iron plate to hold and scoop up the mud.

The iron plates, typically used in large cafeterias for serving dishes and rice, were over a meter long and half a meter wide, capable of holding a large volume of mud. Once nearly full, they were pushed to the edge and emptied into buckets to be lifted out.

Soon, a small Komatsu excavator joined the excavation at the site.

The half-meter-wide bucket looked like a toy, but it was very efficient at work and, indeed, a legitimate tool of productivity.

"Leg."

Someone had found another treasure.

Following that, other scattered remains began to surface.

The only thing missing was the head.

If it wasn't found, they would keep searching. Those who got tired were lifted out for a rest in the basket, and once refreshed, they were sent back down.

At this time, no one talked about overtime pay; it was non-existent anyway. The search continued relentlessly downwards and outwards.

It was through this meticulous work that another hand and toes were eventually found.

As more items were retrieved, the mine shaft became abuzz with voices.

Jiang Yuan was hoisted up again, exhausted.

The mud below was not like solid ground; walking through it required pulling one's legs out with each step, greatly increasing fatigue.

Retrieving items also meant bending over and occasionally carrying weight.

Plus, there was the constant need to identify the retrieved items... to be honest, some of the trash-like items were indeed just trash.

Jiang Yuan rested for a while before rinsing his clothes and limbs with water, then headed to the RV parked a hundred meters away to take a shower.

The RV, dispatched by Xu Taining, was specifically for everyone to shower and change clothes.

To be honest, the logistical support this time was truly in place, so although everyone was tired, there weren't many complaints.

After cleaning up and coming out, Jiang Yuan sat down and drank a cup of tea, only then did his nose begin to detect the normal stench.

At that moment, he felt a slight sense of pleasure.

After resting for about two hours, Jiang Yuan turned on his phone and saw that the small work group had already started discussing the body.

"The body was sawn apart, probably with a chainsaw or similar equipment. It's very similar to the body from the reservoir case."

"The dismemberment was probably for easier transportation, it seems like they don't know much about anatomy."

"Maybe that's just an act. After dismembering enough bodies, even those who don't understand will learn."

Just as the site was about to turn into a large-scale investigative teaching scene, another commotion erupted from below.

Several forensic experts who were resting all ran out from their hiding spots.

Down in the mine shaft, there was another burst of noise, accompanied by rapid commands.

Jiang Yuan went to the edge of the mine shaft and saw a grey travel bag being dug out from below.

"The second body," came a muffled voice from below.
