After all, she is a person who has been through hell once. Wan Yajuan now needs time to slow down so that she can recall what happened before.
But when she was about to speak, she instinctively stopped herself. Her eyes inadvertently glanced at the two elders.
At this moment, Gu Chen roughly guessed the reason. He glanced at Lu Weiwei beside him.
Lu Weiwei understood, supported Zhu's mother and said with a smile: "Aunt, it's okay now. Why don't we go sit in the living room first. I guess your daughter-in-law hasn't recovered yet, so let her calm down."
"It's okay." Looking at Wan Yajuan's scary look just now and everyone's race against time to rescue her, the aunt's heart has not calmed down yet.
When Lu Weiwei said this, she immediately agreed and followed her husband to the living room. Accompanied by Lu Weiwei, they chatted about the thrilling scene just now.
At this time, Gu Chen closed the door slightly and asked Wan Yajuan: "You can finally talk now, right? Who has been here?"
"This..." Wan Yajuan lowered her head in shame.
But at this time, she knew that if she didn't say anything, it might bring even greater disaster.
But after thinking about it, Wan Yajuan was confused.
"Is it Han Dewen?" Seeing that she was still hesitating, Gu Chen directly said what he was thinking.
Wan Yajuan looked at Gu Chen in shock.
"It's Han Dewen, right?" Gu Chen asked her again to confirm.
This time, Wan Yajuan didn't hide anything anymore. She nodded and admitted, "Yes, Han Dewen has been here."
"Why did he come to you?" Officer Wang looked at Wan Yajuan and felt that there must be no good things happening between these two people.
After all, Zhu Huaiping had just died, and the two of them had hooked up.
Regardless of whether what Wan Yajuan and Han Dewen said before is true, but the current situation between the two of them is hard not to make people think wrongly.
"Have you ever looked for him?" After Wan Yajuan calmed down, she clutched her chest and said in pain, "Did you take him to the interrogation room?"
"Yes, the main thing is to ask about the relationship between him and you." Gu Chen did not shy away and directly told the details of his investigation of Han Dewen.
Wan Yajuan is also a smart person and knows that the relationship between herself and Han Dewen must be known to the police.
But Han Dewen was able to come out of the interrogation room, and he obviously had a way to deal with it.
But thinking that she almost died in the room, Wan Yajuan couldn't help feeling sad and angry. She looked at Gu Chen and said solemnly: "It's all his fault and has nothing to do with me. He just feels that life is unsatisfactory, and I walked in
I brought light to his life, so he is pursuing me."
"But you have a husband." Officer Wang said.
"We will divorce immediately."
Wan Yajuan seemed to be possessed by a demon, saying the same words as Han Dewen.
Gu Chen felt that she was hopeless and said bluntly: "What did you talk about after Han Dewen came here? Why are you lying on the bed in a daze? Could it be Han Dewen who did it?"
Gu Chen's words seemed to wake up Wan Yajuan, who was still in a dazed state.
She frowned slightly, raised her forehead to think, and carefully recalled what had happened before.
"Wan Yajuan, I advise you to explain clearly to our police what happened after Han Dewen came here. This time we arrived in time to save you. Maybe next time we won't have such a chance."
Officer Wang warned her in different ways, just to let her know that danger might be around her.
Since she could kill Zhu Huaiping in such a despicable way, if there was really an expert behind her, then the next person to be used as a pawn would most likely be herself.
When Officer Wang said this, Wan Yajuan felt a little scared.
After thinking about it again and again, she still choked and said: "Actually, I don't know why I am lying here, but Han Dewen called me and told me that he was interrogated by the police and felt that he was unjust, so he wanted to come to my place to sit.
"
"Did you fall asleep after Han Dewen left?" Gu Chen's law enforcement recorder was pointed at her.
"No." Wan Yajuan shook her head and suddenly felt dizzy: "I remember... I was after drinking a glass of water, and then... and then..."
"Then you fainted?" Gu Chen followed her words.
Wan Yajuan nodded fiercely: "That seems to be the case."
"Where's that glass of water?" Officer Wang looked around for the glass of water, but there was no trace of it in the room.
But Gu Chen would not think about this.
Because if this was really what Han Dewen did, with Han Dewen's intelligence, it would be impossible for him to leave the evidence at the scene.
Gu Chen now wants to know, did a good person die of suffocation after drinking the problematic glass of water?
But thinking back, Wan Yajuan's face showed no signs of poisoning, but the closed room made people feel a little stuffy.
"But can this cause suffocation?" Gu Chen felt that it was unlikely.
But suddenly, he discovered that there were two sources of wind in the room. Before, he had been observing at the door, and he did hear some subtle movements of the electric fan.
After all, this is an older fan, and it will still make some squeaking noises during the startup process.
But there is an electric fan behind Officer Wang.
"I understand." Gu Chen grinned, looked at Wan Yajuan and said, "It seems that the person who wants to kill you is indeed Han Dewen."
"Wha...what? Han Dewen wants to kill me?" Wan Yajuan's eyes widened, feeling a little incredible.
"If you are still stubborn and unwilling to tell the truth, then I don't think I can save you. After all, if I can save you the first time, I may not be able to save you the second time."
"Gu...Officer Gu, don't scare me, okay? Why did Han Dewen want to kill me?"
Wan Yajuan's face was stiff at the moment. She didn't know whether Gu Chen was trying to scare her by saying this? Or was this really happening?
However, Wan Yajuan is also a smart person, and she feels that if she doesn't ask clearly about the situation, she will definitely not tell the truth.
Just like two people making a deal, if you don't sell the goods first, how can I give you money?
Gu Chen didn't want to play riddles with her. The most important thing for Gu Chen at the moment was to investigate and find out the truth.
So Gu Chen looked at Officer Wang and asked, "Brother Wang, when we entered the door just now, can you tell us what happened at the scene?"
"What's going on at the scene?" Officer Wang didn't know what medicine Gu Chen was selling in his gourd, so he looked around and said, "I only remember that when I came in, the door to the room was closed and the windows were closed."
"Then you, Wan Yajuan, lay motionless on the bed, with an electric fan fanning around you. At first..."
"Wait a minute." Officer Wang said this. Gu Chen did not let him continue, but directly interrupted: "How many electric fans?"
"Just..." Officer Wang looked around and said, "Just two."
"Two, right? When we came to the room, were both electric fans turned on? Or, only one was turned on, and the other one was turned on later?" Gu Chen continued to ask.
Officer Wang was a little confused now. He didn't understand Gu Chen's intention in saying these words, but he still reluctantly thought about it.
After comparing again and again, he finally replied: "Both are on."
"Are you sure?" Gu Chen asked.
"OK." Officer Wang nodded fiercely: "Because the fan behind me is always on. I have been standing here to fan myself, and the wind from the other one is blowing from the opposite side. I can feel it.
"
"These electric fans have been turned on since everyone entered the room. Is this still false?"
After hearing Officer Wang's words, Gu Chen turned to look at Wan Yajuan: "So... you turned on these two fans?"
"No? Why should I turn on two fans?" Wan Yajuan expressed her injustice.
"If it wasn't you, it was Han Dewen who opened it. Can I understand that?" Gu Chen asked again.
Wan Yajuan didn't know how to answer, so she could only nod silently: "That can only be opened by him."
"Very good." After confirming the prerequisites, Gu Chen returned to the previous topic and continued to ask: "Do you usually go to bed at this time?"
"No." Wan Yajuan was confused and said with certainty: "I usually go to bed very late, but I have never gone to bed so early."
"So I can understand that you may have drank water containing sleeping pills." Gu Chen said.
Wan Yajuan was stunned: "Sleeping pills? You mean... Han Dewen gave me sleeping pills?"
"If not, why are you lying here? Even your mother-in-law slaps you and can't wake you up?"
Gu Chen's words were like a bolt from the blue, instantly bringing Wan Yajuan back to her senses.
"Yes, I have only drank one glass of water since I got home, and Han Dewen poured it for me. If this is the case, then there must be something wrong with this glass of water."
Thinking of this, Wan Yajuan suddenly took a breath of cold air and hugged herself tightly in fear: "How...how could this happen? Why did Han Dewen kill me? Why?"
"Why should you know it yourself?" Gu Chen felt that this question should not be answered by himself.
After all, the Wan Yajuan in front of her was originally a poisonous woman.
If she is to be cured, the mountains must be higher than the other, and the people behind her must be more cruel than her.
Wan Yajuan was a little confused, but couldn't believe it. She asked Gu Chen: "Even if the cup of water in question was tampered with by Han Dewen, but...but why am I like this? Is there anything that can make people
Water that suffocates death?”
"Of course not." Gu Chen objected, but looked at the two floor-standing electric fans in the room: "But electric fans can do it."
"Can electric fans kill people?" Wan Yajuan snorted twice and couldn't help but curl her lips and said with a smile: "Officer Gu, I think you are joking. This may be because Han Dewen was afraid that I would be hot, so he let me sleep on the bed.
opened."
"It seems that you still have illusions about Han Dewen." Gu Chen was a little disappointed.
Wan Yajuan seems to still be imagining her beautiful life in the future after her husband Zhu Huaiping falls from the building.
Unfortunately, she didn't know that Han Dewen was not only entangled with her, but Han Dewen was also a master of time management and dated different women at the same time.
For such a sanctimonious person with a human face and a beastly heart, how can you expect him to give you happiness?
Gu Chen felt that the reason why Wan Yajuan trusted Han Dewen too much was mainly because Han Dewen looked good.
Under the disguise of a gentle appearance, she lost herself.
In order to make Wan Yajuan give up, Gu Chen still explained: "If I guessed correctly, you should be taking the sleeping pills prepared by Han Dewen for you, but the dosage of these sleeping pills is absolutely impossible to cause death."
"And the only thing in the room that can kill you is these two fans placed in parallel."
"Fans placed flat...parallel?" Upon hearing this, Officer Wang was also confused. It felt like this was the first time he had heard this statement.
Wan Yajuan was even more confused. She had never heard of such a statement at all, and couldn't help but sneered: "I don't understand."
"You don't understand. I will let you understand, and I won't let you still speak for that person even though you are being plotted against."
Gu Chen walked to the middle of the fans, pointed at the two fans and said, "When the two fans are parallel and blow in one direction, an air pressure will be formed in the middle."
"The high-speed airflow prevents outside air from coming in, so the air in the middle area is reduced, and because you have taken sleeping pills and are in deep sleep, you cannot wake up at all. Therefore, when two fans blow towards you, it will cause you to suffocate.
die."
"Is there still such a thing?" After hearing Gu Chen's words, Wan Yajuan was almost frightened.
Looking at the two ordinary fans in the room, they turned out to be the tools Han Dewen used to murder himself?
Thinking of this, Wan Yajuan couldn't help but take a breath of cold air, her whole body seemed unsteady.
Officer Wang stood between the fans, carefully considering Gu Chen's words, and asked without knowing why, "Gu Chen, what is the principle of this? Is it really so magical?"
"Of course." Gu Chen didn't want to beat around the bush with Officer Wang and said straightforwardly: "According to Bernoulli's principle, the greater the speed of the fluid, the lower the pressure of the fluid."
This chapter is not over yet, please click on the next page to continue reading! "And two parallel electric fans blew air towards Wan Yajuan who was sleeping. The pressure where the electric fans blew was low. People in places with low pressure would naturally not be able to carry out any activities.
Normal breathing is mainly due to the inability to inhale, which leads to suffocation."
"The principle is very simple, because inhalation requires the external atmospheric pressure to be greater than the air pressure in the chest, so that external oxygen can enter the human body and ensure the normal survival of the human body."
"As for Wan Yajuan, whom we saw when we entered the room just now, it was because of these two electric fans that she couldn't breathe."
"But, when I feel uncomfortable, won't I resist?" Wan Yajuan asked.
"But aren't you unconscious?" Gu Chen knocked her back with one sentence.
Seeing that Wan Yajuan was confused, Gu Chen continued: "The electric fan should not be placed very close to the body. If there is a strong wind blowing nearby, and only blows on one side of the body, the sweat on the wind-exposed side will evaporate quickly.
The temperature dropped significantly."
"On the side where the wind is not blowing, sweat will evaporate slowly, causing the gap between blood circulation and sweat excretion on both sides of the body to be too large, and the nerve center will lose balance."
"Once it lasts for too long, all the organs will be exhausted, and you will feel uncomfortable all over the body."
Seeing that Wan Yajuan was understanding it carefully at the moment, Gu Chen added: "But if the air flow velocity at the person's location is very high, according to Bernoulli's principle, the atmospheric pressure will decrease. When it decreases to approximately equal to the air pressure in the person's chest, enter
The human body will have very little oxygen, so it can easily lead to suffocation.”
"But there is a problem. Generally, when people feel uncomfortable, they will wake up naturally, and it rarely causes people to suffocate to death."
"But you were in a coma at the time, so under these conditions, if no one found you in time, I'm afraid you would have suffocated and died in the room without knowing it."
"It's too scary." Wan Yajuan covered her face with her hands and sat paralyzed on the ground in fear.
She looked up at Gu Chen in despair, and said with a slight hesitation: "Don't this situation exist in theory? Is it so accurate?"
"You're still defending Han Dewen." Gu Chen bluntly told her what was in her heart. He also shook his head and sighed: "It seems that he is really capable of asking you to kill his husband."
"I...I killed my husband?" Wan Yajuan expressed her grievance and retorted to Gu Chen: "Officer Gu, what do you mean by that?"
"It means that you deliberately pretended to be ill and went to the hospital to get prescription drugs, saying that you were taking them yourself. But what happened? We found all the drugs that you had prescribed in your husband Zhu Huaiping's body."
Seeing Wan Yajuan's slightly startled expression, Gu Chen stepped forward and asked her: "You should know that these drugs should be banned for patients with depression, right?"
"You...you actually performed an autopsy on him? I didn't authorize it, how could you do this?"
"That's the authority granted by Zhu Huaiping's parents." Seeing that Wan Yajuan still wanted to deny it, Gu Chen was rude and retorted.
"Wan Yajuan, I think you are really pathetic. You clearly know that you were framed by Han Dewen, but you still don't believe it and still have illusions about him."
"Well, today I will let you clearly understand what kind of person Han Dewen is."
Having said this, Gu Chen came to one of the floor-standing fans again and said seriously: "I just said this principle."
"Of course, generally speaking, if you want to cause you to suffocate and die, then two fans can blow air in pairs and just shield your nose and mouth, reducing your oxygen concentration intake, thus causing you to die from hypoxia."
"This requires very precise calculations, and people are not wooden and can move."
"Moreover, generally people who are not severely disabled or mentally retarded will move when they feel uncomfortable."
"For example, if you are holding your breath in the water, it is the same reason if you feel uncomfortable and instinctively go up to breathe."
"As for the person who can complete these operations, I think his IQ is at least much higher than that of the average person. It is simply difficult for other ordinary people to do this."
"So rounding it off, there are only a few people who can be selected and divided. As a top student who graduated from a prestigious school, Han Dewen also specializes in physics. I think among the people you know, apart from him, there should be no one else who can do it.
?”
The scene suddenly fell silent for a few seconds, and Wan Yajuan's eyes were filled with panic, or rather disbelief.
She didn't expect that the man she had always longed for would actually kill her?
If she didn't believe that the murderer was Han Dewen at first, then Gu Chen's evidence would undoubtedly give her a loud slap in the face.
