A beam of light is not bright, it is night, a night as cool as water.

Zhang Xiaoman glanced at the ice cubes in the water at the bottom of the big iron tank that had not completely melted, slowly climbed down from the iron ladder, turned off the flashlight, and said to He Wei who was standing next to him, "The murderer didn't really want to kill Yang Qingqing, the distillation tank is a mixture of ice and water, only after the ice is completely melted, the water will start to heat up, if that person really wants to steam Yang Qingqing, the bottom should be boiling water." ”

He Wei frowned, "Then why did Yang Qingqing fall into a coma due to severe dehydration?" ”

"There are many causes of dehydration, and the high temperature environment is just one of them, and manual workers who sweat a lot may also cause dehydration, and some have other diseases in the body, such as diabetes insipidus, vomiting and diarrhea, etc.," Zhang Xiaoman said as he looked around the chemical plant and found some traces of burned plastic bags in the corners, adding, "In addition, excessive intake of a high-protein and salty diet can also lead to osmotic dehydration." ”

He Wei said with a sad face, "The colleague of the trace inspection said that the murderer did not leave footprints and fingerprints, not even tire prints, now I just hope that Yang Qingqing can wake up as soon as possible, and we can ask clearly......"

"Even if she wakes up, I'm afraid she won't tell us too much," Zhang Xiaoman shook his head, "Yang Qingqing doesn't have any injuries on her body caused by violence, which means that she and the murderer know each other, plus the last place where she disappeared was a hotel, or a room opened with her ID card, she has an extraordinary relationship with the murderer, whether it is out of shyness or fear, she will not tell us too much information about the murderer...... And she may not be able to open her mouth for the rest of her life......"

He looked at Zhang Xiaoman in shock, "Why?" ”

"If I'm guessing correctly, her vocal cords have been destroyed by the murderer......" Zhang Xiaoman picked up a broken brown glass bottle on the ground and pointed to the corroded garbage next to the glass bottle, "She should have been poured some kind of strong acid." ”

At this time, He Wei's mobile phone rang, took out the mobile phone, and quickly connected it, He Wei's face gradually became gloomy, hung up the phone, and said to Zhang Xiaoman, "You guessed it, a colleague in the hospital called just now, and the doctor gave Yang Qingqing an examination, and Yang Qingqing was indeed poured a large amount of concentrated nitric acid into his mouth...... Bastard! ”

"Since the murderer left Yang Qingqing's life, he naturally has to ensure that Yang Qingqing will not talk nonsense." Zhang Xiaoman walked out of the factory slowly, suddenly caught a glimpse of something shiny in the grass on the side of the road, leaned over, played in the grass for a while, picked up a pink mobile phone with a broken screen, and handed it to He Wei, "This should be Yang Qingqing's mobile phone, take it to check, but don't report too much hope, after all, the murderer used this mobile phone to call the police......"

"Uncle Man, what do you say the murderer is doing this?" He Wei took the mobile phone, handed it to the police officer of the task force next to him, touched his chin and thought, "Since you are worried about Yang Qingqing talking nonsense, why don't you kill Yang Qingqing, you have done so many things, and finally took the initiative to call the police to let us save Yang Qingqing, it is too unreasonable." ”

"It's not hard to guess," Zhang Xiaoman squatted down, staring at the tire marks of the police car and ambulance on the ground, "He wanted to punish Yang Qingqing, but Yang Qingqing's sin was not to death, so he added enough ice to the iron can." Call the police...... It was a demonstration to us, a clear sign that he had done all this. ”

He Wei snorted coldly, his eyes were cold, and he said, "It's the first time I've seen a mouse dare to play with a cat, and I'm not afraid to play with it." ”

"What's more," Zhang Xiaoman stood up, "Let me ask you, if Yang Qingqing is really dead, who will be the first object of our suspicion?" ”

"How do I know this, I haven't investigated Yang Qingqing's interpersonal relationship yet, and I don't know who Yang Qingqing has had a feud with......" As soon as he was halfway through the words, He Wei suddenly came to his senses and looked at Zhang Xiaoman in shock, "You mean ......"

"That's right, we just saw Yang Qingqing beat Jinyue not long after we saw it in the villa, and then Yang Qingqing had an accident, and it was bound to focus on Jinyue, but now it's different...... The murderer used the victim's mobile phone to call the police, and told us that it was a man who murdered Yang Qingqing, and it was logical to rule out Jinyue's suspicion. ”

"Why do you keep thinking that Jinyue has a problem? In my opinion, there is nothing suspicious about her......"

"She behaved too normally, which in itself was very abnormal, whether it was the window that had been pried open, or Yang Hai was killed in the study, it was not a common thing, but Jinyue behaved too calmly. Even if Yang Hai died and there was such a major change, she only showed just the right amount of sadness. Well, you have also seen many family members of the victims, and I don't need to tell you what those people are like...... Jin Yue, has you ever mentioned once that you want the police to severely punish the murderer of Yang Hai? ”

He was stunned, recalling the contact with Jinyue during this time, it was indeed completely different from the families of the victims he had seen before, at first glance there was no problem, all of Jinyue's expressions were like a sad and pitiful weak woman who had lost her lover. But He Wei knows that the real family members of the victims are not like this, he has seen those who want to take revenge on the murderer in a frenzy, and he has also seen those who almost drove themselves crazy because of self-blame, and some are also sad, and even calmer than Jinyue on the surface, but in fact, the whole person has undergone earth-shaking changes, and life has been chaotic for a long time.

There is no greater sorrow than the death of the heart, and there is no sorrow than silence. Jinyue is a sound and tangible sadness, but life is still as usual, and she has not forgotten to water the pansies in the flower garden in the morning.

There was nothing to say all the way, He Wei drove Zhang Xiaoman to the hospital, and the two of them didn't speak on the road, maybe they talked too much at the scene of the crime, or maybe they both had a lot of thoughts in their minds and didn't have the heart to communicate anything.

Zhang Xiaoman walked quickly to the emergency room, when he was observing the tire marks on the ground just now, he did not find tire marks on other vehicles except police cars and ambulances, and the murderer's method of eliminating the marks seems to be clever, but it is actually the biggest loophole in this case.

As soon as he walked to the aisle outside the emergency room, he saw the doctor and nurse in surgical gowns pushing Yang Qingqing out, and He Wei and Zhang Xiaoman immediately greeted him.

He Wei glanced at Yang Qingqing, who had already opened his eyes on the cart, and said in surprise, "Awake?" ”

A young doctor with glasses stopped Zhang Xiaoman and He Wei, "Who are you?" ”

"We are police officers......" He Wei explained as he pulled out his ID with an excited face.

The young doctor said unceremoniously, "The patient is just out of danger and needs to recuperate......

He Wei bypassed the young doctor and touched Yang Qingqing's unconscious shoulder, "Be strong, you must hold on, you have to help us catch that bastard and watch him be sent to prison by us, so you must live and tell us everything you know......"

Yang Qingqing suddenly trembled on the cart, trembling violently like an electric shock.

"She's been doused with a lot of concentrated nitric acid, and her entire throat is badly damaged," the young doctor next to her whispered, "I can't answer any of your questions......

He Wei sighed heavily, "I know......" looked at Yang Qingqing's slender and delicate fingers, "Maybe it's okay to write it down." ”

"Let's wait," said the young doctor coldly, "the patient's condition is not yet stable, and further treatment will be carried out in the future, and even if you ask her now, you will not be able to ask why." ”

Zhang Xiaoman looked at Yang Qingqing, who was constantly crying, and shook his head at He Wei, "With her current state, even if we can get her testimony, it will be invalid, and we will not be questioned until her condition is stable." ”

Yang Qingqing's emotions became even more excited, his eyes widened, and he looked at Zhang Xiaoman and He Wei with a hideous face.

The young doctor leaned over and looked at Yang Qingqing softly, "Does it still hurt...... It's good to wait a while, just finished the sedative, and it will take a little time, so bear with it. ”

Yang Qingqing no longer looked at Zhang Xiaoman and He Wei, followed the voice to look at the young doctor, blinked his eyes hard, and saw the young doctor's face clearly, handsome and resolute, with clear outlines, bright eyes, warm and gentle. Slowly, Yang Qingqing calmed down, but tears still flowed from the corners of her eyes.

Zhang Xiaoman stood in place, watching Yang Qingqing being pushed into the intensive care unit by the medical staff, and the moment the door closed, he saw Yang Qingqing's bloodshot eyes still staring at him and He Wei wetly.

At this moment, He Wei's mobile phone rang again.

"Boss, we just got an important clue from the colleague in charge of the counterfeit banknote case, there is a bag of fake jewelry in the stolen goods they seized, and after investigation, it was found that the style of these jewelry is exactly the same as the one sold in the villa's hostess's store......" The excited voice of the police officer of the task force came from the phone, "I followed this line and found that these fake jewelry came from the wrong way, and they only appeared outside recently, do you think this is related to the case we investigated......"

He Wei pursed his mouth, replied blankly with an "oh", his eyes were still on the door of the intensive care unit, and said perfunctorily, "These two cases can't be fought together, you think too much, it's the right thing to investigate the nameless corpse, how is the investigation of the nanny Aunt Cai going?" ”

"The intermediary agency didn't have Aunt Cai's detailed information, but simply registered her name, age and contact number, and didn't know where Aunt Cai's hometown was," the task force member said helplessly, "It's like it appeared out of thin air and disappeared out of thin air, it's not easy to check......

Zhang Xiaoman, who was standing on the side, suddenly remembered that Zhang Yunxi had told him before, at first Zhang Yunxi suspected that the villa was a thief, and Jinyue's explanation was that Aunt Cai was a thief, her eyes lit up, and she said to He Wei, "Let them continue to investigate, there are still two strange footprints in the photos taken by Nie Yi and Li Jun, and if you find out the thief who stole the jewelry, you may have unexpected gains!" ”

He Wei immediately instructed the members of the task force to continue to investigate the fake jewelry case, hung up the phone, rolled his eyes, and said to Zhang Xiaoman with a strange expression, "Uncle Man, I think of a person, maybe he can find the thief who stole the jewelry faster than us......"
