Next, Fengchen and Ding Kui interrogated the three of them, but the three of them kept silent about the "poison" and kept shouting 'I didn't kill the person'.

After coming out of the interrogation room, Ding Kui asked, "Next, are you going to interrogate the last person?" ”

"No, I can't ask for any clues. Now wait for the results of the search to come out," Fengchen said, waving his hand

"Hmm", Ding Kui let out a deep nasal voice.

Ten minutes later, the unexpected results came out, and Luo Wenye happily reported: "After the search, three of the four suspects were found to contain poison utensils. ”

Ding Kui's face was relieved and he asked, "Which three?" ”

"The poison found in Shang Weidong's body has been tested and confirmed to be **, and chemical fertilizers are commonly used and are also used as medicines.

The poison found in Huang Lin was a mercury-based neurological poison. The poison found on You Junjie's body has not yet been tested to be poison, because it is an unknown item that he has concocted, and it has been sent to the forensic team for testing. ”

"Well, in this case, You Junjie is the most suspicious," Ding Kui said after a moment of silence

Fengchen's face was not happy, but frowned, because he felt that all this was too unreasonable, and the character who could prepare his own poison would be the kind of person who couldn't even hide the evidence? He thought for a moment and asked, "Where was the poison found on them?" ”

Luo Wenpage looked at the report sheet in his hand and replied: "Poison utensils were found in the pockets on both sides of You Junjie and Huang Lin's jackets, and Shang Dongwei found poison utensils in the left pocket of his pants."

"No, it's too unreasonable", Fengchen muttered to himself, and then said to Ding Kui: "Let's go and question those three people face to face, the truth will never be so simple."

"Well, I also think it's strange, let's go and see the reaction of the three suspects, let's go", Ding Kui finished speaking and left, time is limited

When they came to an office, the four suspects all looked around with their heads probed, and they did a good job of hiding some uneasy emotions.

Fengchen said directly to the three of them: "The police have found the poison container on the three of you, so you are now officially listed as suspects, do you have anything to say?" ”

When the three of them heard this, their expressions were dull, revealing an 'impossible' situation. Then he realized that there was a police officer in front of him, so he returned to his normal expression and remained silent.

"It has an effect", Fengchen was overjoyed in his heart, and was ready to break them one by one: "Mr. You, we found an unknown toxic substance in your jacket pocket, I don't know how you can explain it?" ”

Unexpectedly, You Junjie laughed after listening to Fengchen's questioning, and said with a clear conscience: "That's not my thing, it must be the murderer who heard that I had a holiday with Yun Jinju somewhere, and wanted to blame me for the crime." So put the poison on me, I was wronged".

"Huh~?" You Junjie's series of expressions all fell in Fengchen's eyes, forming a suspicious point. Then Fengchen asked Huang Lin and Shang Dongwei in the same way, but all they got were their reactions of 'having a clear conscience'.

"Hehe, it's none of my business, and I don't know the dead person, can I leave?" At this time, the contestant who was the same age as Fengchen spoke. He didn't understand why he was stayed, but he couldn't refuse the police's request. Only then did he know that he was being suspected by the police, so he didn't want to continue to get involved.

"What are you laughing at, you are the most suspicious, you want to leave? No way! The wind and dust directly shattered the other party's hopes.

"Actually, I never understood why you left him behind," Ding Kui said.

"Does that need to be said? Of course, I have taken a fancy to him, a computer master who is about the same age as me, and it is the most suitable to be my computer consultant", of course he can't say this, Fengchen has his own idea in his heart, and he said: "Because he is very similar to the deceased's method of cracking the code during the game, maybe it contains a story of 'grievances and hatreds of pirated stories'."

"Oh, that's right", Luo Wenye was completely fooled, and nodded in a conscious way. But Ding Kui was thinking about what Fengchen said, which was reasonable.

The person who is the same age as Fengchen is called Zhu Liang, and this time I heard that there are many computer master competitions in this computer city, so I was itchy for a while and participated in the competition, but I didn't expect it to be in trouble now.

Zhu Liang hung the corners of his eyes helplessly and asked, "Then why do you say that I am the most suspicious?" I don't have any poison on me~."

"It's because you don't have poison on you that you're the most suspicious. You don't have any poison on you, maybe it's because you've used it.

The poison used by the killer this time was a self-concocted drug, at least I have never seen this poisoning symptom. It can be seen that the murderer is cautious and will never let a vessel containing poison appear on his body", Feng Chen's explanation is the way, reasoning with him, you have to weigh it, he can instantly point out some subtle clues, and charge you with the crime.

"This reason is too far-fetched," Zhu Liang said unconvinced.

But Fengchen ignored Zhu Liang's complaints, but sighed rather regretfully: "Of the three poisons known now, only ** can be ruled out, because ** is not an unknown poison." I thought Mr. Shang could clear his suspicion, but you said it wasn't yours, so your suspicion still exists."

When Shang Dongwei heard this, he was dumbfounded, and he gave up an opportunity to clear his suspicion. He hurriedly changed his words and said, "That...... Mr. Policeman, this *** is mine".

"Oh? Then why didn't you just say it? ”

Some yelled angrily

Fengchen shook his head and sighed: "Don't you still understand? As soon as the bottle is opened, the molecules inside are drained out, and you keep the utensils in your pockets for a while after applying the poison. Just do it and you can detect the drug molecules in your pocket. I think

"What else do you have to say now?" Seeing that the three of them were silent, Fengchen continued: "Since you don't speak, then I will take it as your acquiescence. Next, I will return these three drugs to their original owners."

He handed out the three evidence bags in his hand to the three people, one for each person. The three of them looked at the poison vessel in their hands, their faces were complicated, and they did not refute.

This is strange, Ding Kui asked, "The results of the investigation have not yet come out, how do you know who the owner of these poisons is?" ”

"Because from the time You Junjie doesn't understand what disease ** is curing, you can be sure that ** is not his; And Shang Dongwei's eyes wandered, obviously lying, so, ** is not his. Therefore, ** is all the things that are left in the Yellow Forest. Fengchen explained with a smile

"And what about the other two?"

"This is what I speculated, because Shang Dongwei almost fell down before he came to the stage, but he grabbed You Junjie's clothes in time, and the poison should have been stuffed into it at that time.

In this way, it is very clear, the mercury nerve poison is You Junjie's, ** is Huang Lin's, and the nameless poison is Shang Dongwei's"

"Oh, I see! But does this have anything to do with the case? ”

"Unrelated"

"......", Ding Kui was on the verge of collapse, and he calmed down...... He took a deep breath and said, "Since it's not related, why are you still talking about this?" ”

"Because this is also my duty, the three of them must bear criminal responsibility for attempted murder," Fengchen said solemnly

"Well, I understand, Xi ......", Ding Kui reacted at this time: "Wait......, attempted murder?" What do you mean? ”

Fengchen shook his head and said nothing.

"Brother Fengchen, I have completed everything you want me to do, this is the result report", just when Ding Kui wanted to continue chasing

The three members of the detective group above were rummaging through the archives of the police station for information on the serial disappearances of the year, while Fengchen and Xue Yawen below were anxious about food and water.

Before meeting Fengchen, Xue Yawen was only eaten a hamburger and some water in the four days that she was taken captive into the crypt. So, after a while, she ate all the biscuits on Fengchen's body.

After that, the two of them were blind in the crypt for a long time, at this time both of them were hungry and thirsty, and Xue Yawen's body temperature was getting higher and higher, and the high fever made her a little dizzy.

Generally speaking, a sudden outbreak of high fever (38.5°C-40°C) usually means that there is a bacterial infection in the body: acute inflammation such as cold, pneumonia, meningitis, scarlet fever and so on will be accompanied by a high fever.

Urgent treatment should be given, with cold compresses and baths to cool the patient as quickly as possible. You can use a cold and wet towel to compress your forehead, and you can use a watertight plastic bag to hold ice cubes and wrap a dry towel on your head and neck; It is more effective if applied to the armpits and groin. You can dilute 75% alcohol with water and wipe your head, neck, armpits, chest and back and limbs with a small towel dipped in moisture.

Fengchen helped Xue Yawen to move on, and kept thinking about how to find a water source and do emergency treatment for a high fever.

You can't see anything here, it's not easy to find a water source, everything can only be done by your own senses.

No wonder none of the people who got here escaped back then, no, it seems to be one! [If the policeman can get out, I can get out] is the hope that Fengchen is now unquenchable.

Life is precious, and he does not allow others to waste it, and he certainly won't waste it himself.

When the palm of his hand touched a piece of soft soil, Fengchen came back to his senses, slowly became emotional, and touched the rock wall next to him.

The soft dirt, the mossy walls, and this peculiar smell are, yes, swamps, and there must be swamps nearby.

Swamps can be divided into woody swamps, herbaceous swamps, and moss swamps (high marshes) according to plant types.

According to the soil type, marshland can be divided into two categories: peat bog and latent bog. According to the source of water in the soil, marshland can be divided into: low-level swamp, which is recharged by surface water or groundwater, contains minerals, and is also known as eutrophic swamp; High swamps, which are fed by rainwater and are nutrient-poor, are also known as oligotrophic swamps; Median swamps, fed by a mixture of rainwater and surface water, are also known as mesotrophic swamps.

All rocks with good permeability and large voids, as well as pebbles, coarse sand, loose sediments, rocks rich in fractures, and rocks developed by karst can be aquifers. Geologically, an aquifer often refers to a saturated layer below the soil aeration layer, where the pores of the medium are completely filled with water. There are many types of aquifers, such as the aquifer is directly covered by impervious strata above and below, and the groundwater fills two layers of impervious aquifers, which are referred to as restricted aquifers. If there is no impervious layer above the groundwater surface, the water surface is the groundwater level, which is called the non-confined aquifer.

Although the swamp water on the ground is dirty, it has been filtered by the rock walls and mud and is barely enough to be used as groundwater.

Fengchen wanted to leave here to find the location of the swamp, but if he got lost and couldn't find the swamp, then Xue Yawen would be in danger.

The best thing to do now is to dig a big hole in the soft soil, and bet that there is a 60 percent chance of water seeping out.

Leaned Xue Yawen's back against the stone wall. Since there were no tools, the wind and dust had to be dug with bare hands.

After digging almost half a meter deep, the mud mixed at the bottom of the pit could faintly feel the presence of water, and after digging for a while, he leaned against the rock wall a little out of strength, panting.

He sensed that his chest was already wet, not from sweat, but ...... The wound opened again, but the wound did not open much, but the blood still flowed, and the flow was very slow, but it could not withstand the long period of consumption.

If he can't find an exit, he will probably be the only person in this crypt who is not starving.

During the break, Fengchen kept chatting with Xue Yawen and didn't let her sleep, she had already slept for a day before, and she might not be able to wake up if she slept again.

Half an hour later, Fengchen reached into the pit, and with a bang~, he touched the water, which was about ten centimeters deep.

Holding the water in his hand, he sent it to Xue Yawen's mouth and fed it carefully.

Feeding it several times, until Xue Yawen said that he would not drink it, he held the water and drank it himself.

It may be that the water has become turbid again after holding the water several times, and the wind and dust are full of sand anyway.

After satisfying his appetite, he put his clothes on the rock wall and grinded three pieces of cotton cloth, soaked them in water, and then wrung them out, one on Xue Yawen's forehead, and the other two on her armpits.

After that, the two chatted again. I don't know how long it took, Fengchen didn't want to sit still like this anymore, and said: "Xue Yawen, I think I'd better go and find the exit, you just wait for me here, there is water here, and I won't die in a few days."

Xue Yawen hurriedly shouted: "Don't, I'll go with you."

"You're having a high fever now, and you're going to have to rest well to survive until the day you get out."

Xue Yawen said stubbornly: "It's okay, I can still go."

"But ......, well, well, give me your hand."

Fengchen thought about it and felt that it was not a way to leave Xue Yawen here. In case he gets lost, Xue Yawen will die if he stays here. Moreover, even if he found the exit, he didn't have the physical strength to come back to pick up people, and the ending was ......

"Hmm!" Xue Yawen clenched Fengchen's hand, if she used to write love letters to Fengchen just because of worship, then now she is infatuated.

Along the way, Fengchen's face became more and more pale, and the blood was almost soaking his pants. It's better not to walk, and the wound may stop bleeding.

The two of them were so weak that they had no sense of time, and they just knew that it was right to keep moving forward.

Fortunately, the efforts made were not in vain. The jagged rock wall finally turned into a smooth wall, and although it was still very dark around, the wind and dust vaguely guessed that this was probably the living area of the crypt.

As the wall kept touching, it didn't take long to come across a stone platform, which was in the shape of a bowl and contained water, no, it should be fuel.

He picked up two small boulders next to the stone platform and slammed them hard, causing sparks to erupt from the boulders. Taking advantage of this brief light, he locked the position of the wick and quickly lit the oil lamp with flint.

The surroundings lit up, and the long-lost light made Fengchen breathe a sigh of relief, even if it was him, he couldn't stand the depression of staying in the dark.
