The vertical well was about four meters deep.

Under the cement floor that had been chiseled open was rough soil.

Only one person could climb up and down the vertical well, and the narrowest part could only allow one person to pass through. The area at the bottom was slightly larger, presumably for the convenience of construction.

The horizontal well had a larger volume of soil and sloped down at an angle of more than two meters. The main part of the basement was two meters high, with an area of about ten square meters. It had been converted into a ventilation device using a chimney, although the air was still polluted, it was capable of long-term survival.

What was even more surprising was that there was a computer in the dungeon. It couldn't access the internet, but it should be able to be used for entertainment.

Jiang Yuan remembered the three disheveled, terrified, and nervous women who had just climbed out, feeling as though his skin and veins were tightening all over his body.

Jiang Yuan only glanced at the door and stopped his footsteps rationally.

He was curious, but for now, this dungeon of less than 10 square meters was full of evidence, and he had almost no suitable investigation equipment in his hands except for a flashlight and a mobile phone. He didn't even have a field investigation pedal. If he stepped in now, the entire scene would be covered in his footprints.

If it were an ordinary small case, there were many ways to extract evidence without specialized equipment. For example, a bed sheet covered in strange substances could be rolled up by a police officer or torn and placed into a plastic bag as evidence.

However, today's case had nothing to do with small cases. Therefore, even a footprint on the ground could be very important. When Wen Ming came down just now, he may have been eager to save people or may not have paid attention, and had already walked around the scene. However, if it was limited to his footprints, it would not have too much impact.

Still, it must be limited to Wen Ming's footprints. Otherwise, if three or five people entered the 10 square meter dungeon, the footprints, fingerprints, and even other traces inside would be messed up, which would mean that the scene was completely destroyed.

Therefore, Jiang Yuan could only stop at the door and take photos. After that, he used warning tape to seal off the entrance.

Afterwards, he began to extract fingerprints and footprints from the door lock and other places on the spot.

In the eyes of Wen Yong or Wei Zhenguo, today's case may have already nailed Tan Yong, but in Jiang Yuan's opinion, it was not necessarily the case.As usual, if it were a small case, Tan Yong would be the one to take the blame. But once a case rises to the level of possible death penalty, the rigor of the evidence required will be epic. Although the final result may still be good, the interrogation process in between will definitely be memorable for every police officer involved.

The police and the criminals are often in a state of information asymmetry. Many cases have problems because of this information gap. For example, now everyone speculates that Tan Yong's DNA may be all over the dungeon, but this assumption is definitely not rigorous. What if Tan Yong is willing to wear protective clothing every time he goes to the dungeon?

Someone may say, what about when he has sex? First of all, he may not necessarily have sex, what if he can't get it up? Secondly, what if he likes to wear protective clothing when having sex?

Some people may argue that there are no such perverts! Then they should take a look at this dungeon.

After taking a few fingerprints and footprints and doing the most basic insurance, Jiang Yuan carefully exited the dungeon and climbed to the surface.

At this time, four police officers from Changyang City Criminal Investigation Team also arrived at the scene.

...

"Gan Liang!"

"Oh my God!"

The police who came in saw the deep well underground and then looked at the three women who were trembling, and they were all feeling bad.

It is said that the police have seen a lot of darkness in society, and their endurance is also extremely good. But ordinary police officers have not been trained to see the darkness of society, and the so-called experience is also gradually gained.

And what they saw today obviously refreshed their understanding of the darkness of society.

"This is simply..."

"Are there really people like this?"

Four criminal investigators stood in the four-room apartment, looking here and there, and their entire bodies were cursing.

Jiang Yuan's mood was even worse.

Compared with the criminal investigators, he has experienced less but knows more. The scene in the basement is more likely to make him imagine a lot of details.

"How is Mu Zhiyang doing?" Jiang Yuan asked, looking at Ding Lan who was shivering, across Wei Zhenguo, but didn't know what to say.

Wei Zhenguo quickly withdrew from the bad mood and said, "I'll make a phone call and ask."

Speaking, Wei Zhenguo took out his mobile phone and wanted to go to the bedroom to make the call.

The three women followed him naturally, and they followed suit.

Wei Zhenguo was taken aback, but then smiled and said, "It's okay, I'm just making a call."

Ding Lan raised her head slightly, looking pitifully at Wei Zhenguo, tears falling one by one."Okay, drink some water first. We'll wait for the car to arrive and then head back," Wei Zhenguo quickly reassured them.

"I want to make a phone call...we want to call our families," Ding Lan took the opportunity to make a request.

"We've already contacted your families. With such a big matter, I think it's best to talk to them face to face. What do you think?" Wei Zhenguo's intelligence as an experienced police officer gradually kicked in.

The three of them looked at each other and hesitated.

Indeed, after being kidnapped for so long, making a sudden phone call to their families would lead to unknown consequences. They couldn't guess what would happen.

This doubt immediately reduced their urge to make a phone call.

Wei Zhenguo breathed a sigh of relief. The case today was too big and the situation at the scene was complicated. It would be best to give them their phones after recording their statements.

During this time, Wei Zhenguo sent a message to Mu Zhiyang and waited for his reply.

Soon, Mu Zhiyang's call came back, panting, "Master, we caught the person who's uglier than me."

"Good! It's great that you caught them. Was there any unexpected situation? Did you encounter any danger?" Wei Zhenguo asked.

"No, everything went smoothly. The four of us rushed in and handcuffed them directly. Everyone is safe," Mu Zhiyang said.

"That's good. Pay attention to the procedures. The prosecution may directly intervene in this case..." Wei Zhenguo whispered a few words of caution before hanging up the phone, feeling relieved.

With this, the main part of the case had been successfully completed.

Wei Zhenguo turned around and looked at Ding Lan and the others who were still uneasy. He couldn't help but feel a sense of emotional relief after surviving the ordeal.
