At this moment, the air was filled with the smell of cow dung, and everything around him looked extremely strange.
The central location of Hejiang Village is clean and tidy, and many people even open farmhouses. Therefore, things with rural characteristics such as cow dung do not exist at all.
But the old house in the northeast corner is different. There seems to be a cowshed not far away. Everyone has searched Hejiang Village before, but most of them visited the residents and did not notice this old house.
In addition, there are trees between Hejiang Village and the old house, so it looks more like an abandoned old house.
"No wonder." Gu Chen couldn't help but muttered.
Lu Weiwei said dumbly: "Junior Brother Gu, what's the reason?"
"No wonder the police dogs stopped searching around Hejiang Village because the smell of cow dung interrupted the police dogs' sniffing."
"So that's it?" Listening to Gu Chen's explanation, it seemed to make sense.
The police dogs had searched until this point and indeed stopped sniffing further.
But at first, everyone thought that Liu Wenjing left in another vehicle.
But then everyone checked the surveillance at the entrance to and from Gaoqiao National Forest Park on the day Liu Wenjing disappeared, and checked every vehicle entering and exiting, but no trace of Liu Wenjing was found.
Therefore, the idea of leaving by other vehicles is untenable.
But this fat man suddenly reported his brother, which surprised everyone.
But then, the police dogs stopped searching.
At this point, the smell is obviously covered up by the smell of cow dung.
"Is Liu Wenjing in the old house?" Xu Sitong narrowed his eyes, feeling that something was fishy.
Gu Chen didn't hesitate and said directly: "You'll know when you go in and take a look."
As everyone began to surround the old house, Gu Chen led the police dog and first came to the door of the old house.
Since it is an old house, the door is only blocked with iron bolts and not locked.
Therefore, Gu Chen easily pulled away the iron bolt and pushed open the door.
An old rural house like this does not need any door locks at all, and there are no valuables placed inside.
What's more, according to the fat man's words, this is just a temporary resting place for the brothers while they are working here.
Gu Chen stood at the door and looked around, and found that the house was in a mess. In addition to an old wooden bed, there were also some daily necessities.
Turning to look at the fat man, Gu Chen asked him: "Can I go in and search?"
"Okay, this old house is used by the villagers to store debris, there are no valuables," the fat man said.
Gu Chen nodded and crossed the threshold directly.
Then the police dog's leash was untied.
The police dogs immediately rushed forward and sniffed every corner.
Because the light was dim, everyone even turned on their flashlights and searched the dark places.
It looks weird here.
The dilapidated old house and wooden beams are filled with a rotting smell.
However, it can be seen that the old houses have been repaired and reinforced, ensuring the integrity of the building to a certain extent.
But during the search, the search and rescue police dog smelled the smell and suddenly started barking at a closet.
This movement attracted everyone's attention.
Gu Chen immediately walked to the closet and opened it gently.
At this time, the police dog was still barking and seemed to be particularly wary of sensitive objects.
Gu Chen then took out his flashlight and shined it into the closet.
With the blessing of his master's level of observation, he suddenly discovered traces similar to blood stains around the closet.
Gu Chen immediately took off some clean paper towels, extracted the coagulated blood objects, and then carefully put them into the evidence collection bag.
After completing this operation, Xu Sitong asked: "What kind of blood is this?"
"I don't know, but it's best to leave it to your technical department for testing." Gu Chen said.
Xu Sitong immediately agreed: "This is no problem, just leave it to me."
Taking the coagulated liquid suspected to be blood extracted by Gu Chen, Xu Sitong looked around and continued to observe other corners.
Gu Chen, on the other hand, opened all the closet doors at once and visited every corner of the room.
Since it is temporarily impossible to determine whether the coagulated object extracted from the closet is human blood, it is therefore impossible to determine whether it is Liu Wenjing's blood.
After searching the entire old house for a long time, Gu Chen found no more suspicious clues.
At this moment, the police dog seemed to have found some suspicious clues somewhere in the house.
The police dog kept scratching the wooden board with its front feet and made "squeaking" sounds from its mouth.
Gu Chen noticed this and pushed the police dog aside. He squatted down and knocked on the floor a few times.
"Empty?" Gu Chen raised his head and looked at everyone.
Lu Weiwei quickly turned her attention to the fat man and asked him: "Is there a basement here?"
"Yes... yes." The fat man nodded, indicating his acquiescence.
Gu Chen then also discovered the gap between the wooden boards, which was obviously different from other floors.
But there are no handles on the floor here, so it can't be pried open with bare hands.
Gu Chen simply took out the police dagger from his belt, inserted the tip of the knife into the side corner of the board, and then gently picked it up.
The board then creaked and half of it was pried out.
Lu Weiwei grabbed the edge of the board with her bare hands, and worked together with Gu Chen to open the board.
At this moment, an empty and dark basement suddenly appeared in front of everyone.
Seeing this scene, everyone felt excited and anxious.
Secret passage? This is something that often appears in TV dramas.
Now that Liu Wenjing is missing, everyone has been tracking her here. It seems that according to normal logic, maybe Liu Wenjing was killed and hid in this secret passage.
Ninety percent of everyone here has this inner thought.
Xu Sitong's heart couldn't help but he pointed at the entrance of the secret passage and said, "Would you like to... go down and have a look?"
"Of course." Gu Chen said.
"Then let me go." Zhang Kai felt that he was a little transparent here. Given the opportunity to perform like this, he would naturally not miss the opportunity.
So I took a flashlight and shined it around the entrance of the secret room. I found that there was no big problem, so I asked, "Is there a ladder here?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Yes." There was a small wooden ladder next to Yuan Shasha, so she quickly moved to Zhang Kai.
Zhang Kai put down the wooden ladder without saying a word and started to climb down with a flashlight.
But at this moment, Zhang Kai was suddenly grabbed by Gu Chen.
"Are you going to go down like this?" Gu Chen asked.
Zhang Kai was a little confused: "What else?"
"If you continue like this, you may never be able to come up again. Come up first." Gu Chen pulled Zhang Kai up to prevent Zhang Kai from climbing down the stairs.
Zhang Kai was also speechless: "There's nothing down here. I just looked at it with a flashlight."
"That's not the problem." It felt like Zhang Kai didn't understand what he meant, so Gu Chen quickly explained: "This kind of rural cellar, due to long-term sealing, the oxygen originally existing in the cellar will react with the plants inside to generate waste gas, which will last long.
If you don’t use the time and let it go rashly, you may suffocate and die.”
"So that's it? After hearing Gu Chen's words, Zhang Kai suddenly realized.
I also knew it, but just now in order to go down first, I forgot all this for a while.
Fortunately, Gu Chen reminded me just now. Otherwise, if this situation really happened as Gu Chen said, wouldn't he be killed on the spot in a matter of minutes?
Thinking about this, Zhang Kai also took a breath: "Fortunately, you had Captain Gu to remind you, otherwise I would have been too hasty."
"What should we do?" someone in the crowd asked curiously.
Gu Chen turned around and explained to everyone: "Before going down, you must check whether there are any hidden dangers of collapse. You must also ventilate before going down."
"Then use the ignition test to check the oxygen density inside. However, at this time, you must prevent flammable gas inside and be prepared for fire prevention at any time. If the oxygen is not enough, you should add oxygen."
"After all, due to the respiration of plants, carbon dioxide gas will continue to accumulate in the cellar. When the concentration is too high, it will directly threaten human safety."
"So generally in order to test the concentration of carbon dioxide, we usually bring lit candles into the cellar.
"If the candle goes out, it means the concentration of carbon dioxide is too high. If the candle doesn't go out, it means the concentration is not high."
"So that's it?"
After hearing what Gu Chen said, many volunteers gathered around nodded their heads. This is middle school physics knowledge, but many people don't pay attention to it in life.
It can be seen that Gu Chen still noticed this and did not let Zhang Kai go down hastily.
At this time, Gu Chen added: "In addition, I need portable oxygen and a safety rope. After ventilation and testing, I can enter the cellar."
"In the event of an emergency, the safety rope can pull people up from the cellar to ensure safety."
"Is it so complicated? Isn't it just a cellar?" The photographer who had been scared to death by Officer Wang was now standing in the crowd.
Officer Wang glanced at him, pointed to the cellar entrance and said, "How about you come?"
"I...I'd better forget it." Seeing Officer Wang's glare, the man with glasses immediately stepped back.
Xu Sitong said: "It doesn't matter. The Blue Sky Rescue Team has these things in their cars, such as portable oxygen and safety ropes. I'll get them."
"Okay." Gu Chen acquiesced.
Not long after, Xu Sitong brought all these items back to the old house.
After conducting various tests, Zhang Kai carried portable oxygen down to the cellar and used a strong flashlight to search every corner of the cellar.
After a while, Gu Chen asked: "How?"
Zhang Kai shook his head: "Except for some rotten vegetables, there is nothing else found."
"Then wait." After Gu Chen finished speaking, he tied another safety rope to himself, hugged the police dog, and carefully walked down the cellar.
Thanks to the help of police dogs, everyone's search was immediately more effective.
Police dogs kept walking around the cellar, trying to sniff out suspicious clues.
But at this moment, the police dog barked again at the bottom of the cellar.
Everyone looked at each other, feeling confused.
"Is there something else down there in the cellar?" Zhang Kai expressed confusion.
Lu Weiwei, who was above the cellar, said: "I remember Xiong Tao, the leader of the Blue Sky Rescue Team, said that this police dog is particularly sensitive to corpse gas. Could it be that there is something buried under the cellar?"
"Is there something buried under the cellar?"
Upon hearing Lu Weiwei's words, the scene suddenly burst into excitement.
Everyone shuddered, thinking this is too weird, right?
If it involves killing people and burying corpses, then that might be possible.
But once this happens to everyone, they still don't want to believe it.
Gu Chen looked at his feet and suddenly his eyes lit up.
He looked up at Xu Sitong and said, "Officer Xu, I remember that the Blue Sky Rescue Team and the police team also transferred a ground-penetrating radar this time, right?"
"You know all this?" Xu Sitong couldn't help but be stunned when he heard Gu Chen's words.
This was the first time I had seen that thing. It was indeed placed on the police car on the roadside.
But Gu Chen can remember this kind of equipment, which shows that Gu Chen still knows something about it.
A school policeman asked weakly: "Captain Gu, what the hell is ground penetrating radar?"
"Ground penetrating radar?" Gu Chen grinned and explained seriously: "Ground penetrating radar... uses an antenna to emit and receive high magnetic waves to detect the material properties and distribution patterns inside the medium."
"Currently it is mainly used in archaeology, mineral exploration, disaster geological survey and other fields."
"So?" I feel that this ground-penetrating radar has this effect. The young police officer who has not had much contact with this thing is also very curious at this time.
Gu Chen continued to explain: "For example, whether there is anything underground, whether there is water seepage, whether the soil has been excavated, etc., can actually be detected."
"Then who knows how to use ground penetrating radar?" Xu Sitong stood up and asked.
"Me." A second-level superintendent raised his hand and said, "I have used this thing before, and I brought it here."
"Okay, you go help Gu Chen and the others." Xu Sitong said.
With everyone's unremitting efforts, the ground-penetrating radar was finally moved to the cellar.
This chapter is not over yet, please click on the next page to continue reading! After debugging, the ground penetrating radar also started to work.
After some careful operations, the second-level superintendent raised his head and said to Gu Chen, based on various supports provided by the data: "Ground-penetrating radar shows that this underground area has been disturbed."
"Are you sure?" Gu Chen asked.
The second-level superintendent nodded: "It should be no problem."
Gu Chen looked up at the cellar exit and said, "Officer Xu, can you get some digging tools? Send a few more people down."
"No problem, just wait for me." After receiving Gu Chen's request, Xu Sitong immediately coordinated from above.
Not long after, four volunteers came to the cellar with tools and followed Gu Chen to start digging the entire cellar.
In order not to affect their work, Officer Wang, Lu Weiwei and Yuan Shasha also blocked other people outside so that there was enough space at the cellar entrance.
So everyone worked together to dig the cellar to a depth of more than one meter.
After forty minutes of meticulous operation, Zhang Kai suddenly stopped moving, looked down, and immediately waved: "Come over and have a look."
"Have you found anything?" After hearing this, several volunteers gathered around him.
Gu Chen stood behind and waited for a reply.
However, after a few seconds passed, everyone covered their noses and stepped back.
Gu Chen asked: "What's going on?"
"There are animal remains," one volunteer said.
Another volunteer also complained: "It is disgusting to bury animal carcasses in this place."
Gu Chen asked again: "Did the ground-penetrating radar only find traces of disturbance at this location?"
The second-level superintendent operating the ground-penetrating radar nodded and said: "Yes, only this location has signs of being turned over, but now it seems that they are just the carcasses of some animals."
"That means there is no trace of Liu Wenjing's body." It felt like it was in vain, and Gu Chen was also slightly disappointed.
But everyone's operations are still very professional, which is worthy of recognition.
Eliminating all impossible situations at least narrows the search scope.
Gu Chen smiled lightly and said, "Everyone, let's go up."
"well."
After hearing Gu Chen's words, everyone climbed up the wooden ladder in order.
Working in a cellar is a hell of a job.
After Lu Weiwei pulled Gu Chen, who came out last, onto the floor, she also said with a wry smile: "Maybe we are in the wrong direction, but at least we can go to Dongjiang Village to have a look."
"Okay." Gu Chen glanced at the fat man and said, "Dongjiang Village, where does your brother live? Can you take us there?"
"Okay." The fat man agreed readily without hesitation.
This also made Gu Chen look at him with admiration.
After all, reporting one's brother requires enough courage and responsibility.
But this fat man obviously did a good job.
While everyone was rushing to Dongjiang Village, Xu Sitong also asked his colleagues to quickly send the blood stains that Gu Chen had found in the closet to the city bureau's technical department for testing.
Coupled with other personnel searching deep in the mountains of Gaoqiao National Forest Park, it can be described as a total mobilization.
The scale of this search is truly rare in the entire Xiping City.
It can be seen that after the media exposed the situation, the chain reaction caused was still huge.
On the one hand, the police are eager to find Liu Wenjing's whereabouts as soon as possible, while the public is eager to follow this matter.
…
…
Dongjiang Village.
When Gu Chen and his team arrived in several police cars, many villagers walked to the roadside.
Especially when he saw a fat man walking into the village with the police, an old man who was also fat suddenly hesitated.
She stepped forward and asked Gu Chen, the leader: "Comrade police, what are you doing?"
"This Mr. Zhao reported that his brother killed the missing girl Liu Wenjing. We are here to investigate the matter."
"What? Did my youngest son kill the missing girl?" After hearing Gu Chen's words, the old lady became furious, pointed at the fat man, and immediately cursed in the local dialect.
Gu Chen didn't understand the Xiping dialect very well, but it could be seen from the old lady's expression that she demonstrated the traditional Chinese way of scolding vividly.
He immediately went up and gave the fat man a slap in the face.
At this moment, everyone was stunned on the spot.
Obviously, the old lady wanted to protect her youngest son, the fat man's brother.
But no matter how much the old man scolded and beat him, the fat man was obviously indifferent to the pain and showed his disdain expressionlessly.
Gu Chen couldn't stand it any longer, so he stopped the old man directly and said, "Old lady, can we not do anything?"
"If I don't do it? If I don't do it, what will happen to this guy?" After the old lady finished speaking, she went to beat the fat man again.
Fortunately, the fat man ducked back and stood behind Gu Chen smartly.
Seeing the old lady blocking the door, pointing at the fat man and swearing, Lu Weiwei stepped forward to stop him and said, "Old lady, can you please cooperate with our investigation? This is a matter of life and death for a young girl."
"No." The old lady was furious, pointing at the fat man and breathing heavily: "Don't believe him, he just made it up to defraud the bonus."
