Chapter 149 Flying Death
Gu Nankai's brain was working at high speed following Shang Lu's words. He had to completely coincide everything Shang Lu said with the scene and his body, so when Shang Lu finished speaking to him, he did not respond immediately, but was still thinking.
After a while, he looked at Shang Lu with a smile on his face and confirmed what she had just said: "Shang Lu, I now feel that your discovery and speculation are correct and can be tested by reasoning."
"Of course!" Shang Lu did not hesitate to acknowledge his own test results. The little girl raised her head proudly, which made Wu Qingluan chuckle.
Gu Nankai then said: "From what you said, the possible course of events was that Chen Hui had something containing sodium on him. Later, when Chen Hui returned home, the sodium on his body came into contact with water, which ignited the sodium."
"But..." Yang Dong spoke at this time. He looked at everyone a little embarrassed and said, "If that's the case, then Chen Hui's death was suicide, or an accidental death."
Indeed, Yang Dong's guess was not wrong. If we follow Shang Lu's statement and Gu Nankai's current inference, it is easy to conclude that Chen Hui committed suicide or died accidentally.
Gu Nankai thought for a while and looked at Yang Dong: "What you said is very likely ."
Shang Lu also nodded and spoke again: "Indeed, it is not difficult to come into contact with sodium. This substance is widely distributed on land and in the ocean in the form of salt. It is also one of the important components of human muscle and nerve tissue. It is not difficult to come into contact with this substance at ordinary times, but it is not so easy to reach the level of causing spontaneous combustion."
Gu Nankai moved slightly, and Wu Qingluan quickly noticed his movement and looked towards him.
"Water." He whispered, and Wu Qingluan quickly brought him the water. Seeing that his hands were inconvenient, she rolled her eyes at him and carefully brought the water to his mouth. Gu Nankai drank the water and felt much better.
"Okay, let's continue." Seeing that the little kids were looking at him and laughing, Gu Nankai said nonchalantly.
Then he continued, "Since it is not easy for sodium to cause spontaneous combustion, we have to consider a few questions. How did Chen Hui come into contact with enough sodium to kill him? How did the sodium get to him? Think about it this way, which one is more likely, suicide or homicide?"
After Gu Nankai finished speaking, he looked at Yang Dong. Yang Dong suddenly understood something and looked at Gu Nankai excitedly. He stood up from his chair and said, "Captain Gu, do you mean to say that the murderer deliberately created the illusion that the deceased died accidentally or committed suicide?"
Gu Nankai nodded: "It is possible, but before we find new doubts, the possibility that Chen Hui committed suicide or died accidentally is still high."
Everyone became depressed again for a while. It seemed that now that they knew the truth about Chen Hui's spontaneous combustion, they were still a long way from finding the murderer.
"Anything else you found?" The investigation into Chen Hui's spontaneous combustion had come to an end. Gu Nankai looked at Shang Lu and asked another question.
"Of course, don't you see who I am?" Shang Lu obviously had a bigger discovery, which could be seen from the emotions revealed on her face at the moment.
"Come on, Shanglu, you're doing great. Your progress is so impressive." Wu Qingluan praised her.
Shang Lu chuckled. Her anger over Gu Nankai's beating seemed to slowly dissipate. Instead, she felt more responsible for her job. She quickly smiled mysteriously, "Guess what the real cause of death of Chen Hui and the unknown victim was?"
"Officer Shang, wasn't Chen Hui's death caused by spontaneous combustion?" Yang Dong was shocked again. He opened his eyes wide and looked at Shang Lu to ask.
"Of course not." Shang Lu blinked playfully.
"Ah, then what was the cause of death?" Yang Dong asked in confusion, with a look of bewilderment on his face.
"Arrow poison." Shang Lu said in a low voice.
"What is that? Curare poison? What is this?" Li Meng was stunned when he heard it for the first time. He had never heard of this before.
Shang Lu continued to smile mysteriously. Seeing that everyone, including Gu Nankai, was looking at her in confusion, she chuckled and nodded affirmatively: "Yes, it was something called curare poison. This was the real cause of the death of Chen Hui and the other victim. It was because of the curare poison that Chen Hui and the other victim did not resist when they were suffering."
"What is this thing? Why is it so powerful?" Gao Yuan asked curiously.
Shang Lu organized her words. She was thinking about how she should explain it so that everyone would find it easier to understand.
After thinking for a while, she said, "The arrow poison has a very famous name called 'Flying Death'. In the past, this poison was used on arrows, so it got this name. This poison must be injected or applied to the subcutaneous tissue. Only then can its lethality be maximized. However, if you just swallow it or inhale its vapor, it is harmless."
"So magical?" After hearing Shang Lu's words, Wu Qingluan's face was full of curiosity.
Shang Lu raised his lips and said, "That's true. If it's injected subcutaneously or intravenously, the victim's muscle paralysis caused by the drug will start from the eyelids and face. Then, the poisoned person will lose the ability to swallow or raise their head. Their pulse will drop sharply. Within a few seconds after the injection, the drug will be transferred to the diaphragm and paralyze it. The victim's cause of death is respiratory failure. The autopsy results show that the liver is inflamed. There is also a phenomenon that the heart of the patient who was poisoned by the arrow will continue to beat even after breathing stops."
"Oh my god, who on earth discovered this thing?" Gao Yuan clicked his tongue twice and said with emotion.
Although Gu Nankai was not familiar with arrow poison, he had an idea when Shang Lu said the four words "Flying Death". He had heard of this thing, but the two words "arrow poison" temporarily disturbed his mind at the beginning.
Then he said, "I've heard that the terrible thing about this poison is that the victim is conscious and can feel all the changes in the body before losing consciousness. In other words, although the victim feels that the body is gradually paralyzed, he cannot call for help or express it with his body. Also, the poison takes between half an hour and forty minutes for humans."
Shang Lu nodded quickly: "Yes, this is the terrible thing about arrow poison, but from another perspective, arrow poison also has benefits."
"What good can this do?" Li Meng was puzzled and tilted his head to look at Shang Lu.
Shang Lu explained: "In medicine, curare-supported drugs can mimic the effects of heart failure. Its medical function is to suspend normal breathing when doctors are rescuing the lungs, and to assist medical staff in installing artificial respirators for patients. Most doctors will use curare drugs as muscle relaxants before surgery to reduce the need for anesthetic doses."
She grinned and shrugged her shoulders slightly. "Of course, if he were a medical killer, his drug of choice would be curare."
Gu Nankai narrowed his eyes: "So it is very likely that the murderer who killed Chen Hui and the other victim must have a better understanding of medicine than the average person."
"Indeed, he might even be a doctor with superb medical skills." Shang Lu echoed Gu Nankai's guess.
Wu Qingluan frowned and continued their conversation: "But how could Chen Hui offend these people? He has only been out of prison for half a year."
Gu Nankai's mind was working rapidly, and after a while he came to a conclusion.
