“Don't do it, it's one of your own!Yan Wei pulled Zhong Li behind him, turned his head and kept winking at Zhong Li, “Don't apologize, hurry up!"”

  “I'm right, why should I apologize?"Zhong Li rubbed his arms and frowned, with a look of reluctance.

  "Hey, where are you right?I..." Yan Wei's liver hurt angrily, and he raised his hand to hit Zhong Li's forehead, but Lu Ming stopped him.

  “A student of our school?Others try to avoid the scene of death as much as possible. What are you doing here?"Lu Ming stared at Zhong Li with the unique gaze of the criminal police. Experience has proved that any abnormal behavior is very important.

  “He is..." As soon as Yan Wei was about to answer, Lu Ming raised his hand to stop him.

  “I didn't ask you, let him answer by himself."Lu Ming said.

  Zhong Li raised his head to meet Lu Ming's gaze: “I am a student of Teacher Liao, and I am here to see him for the last time.”

  Lu Ming was slightly surprised. People's eyes are very sensitive. Ordinary people and the police look at each other, regardless of whether they are guilty or not, they usually quickly avoid them, and Zhong Li dared to meet the gaze of the old criminal policeman, indicating that Zhong Li has either received strong psychological training or has a very different personality from ordinary people.

  “Are you Zhong Li?"Lu Ming recalled a joke made by Liao Feng during his lifetime: "If I die, the first person to see me must be Zhong Li, believe it or not?"”

  At that time, he didn't believe it and made fun of Liao Feng for being naive, but now it seems that Liao Feng is not joking.“You are the Vice Captain Lu that Teacher Liao often mentioned.Zhong Li nodded, his gaze swept past Lu Ming, and finally fell on Lu Ming's right hand holding a cigarette, "Since you quit, don't smoke. Teacher Liao won't like this way of farewell."”

  Lu Ming couldn't help but stay for a while, looking at Zhong Li and then at the smoke in his right hand. With his many years of observation experience in criminal police, he couldn't understand how Zhong Li could tell it for a while.

  “May I go in?Zhong Li pointed to the scene of death.

  “It should be, come with me."Lu Ming didn't stop anymore, nodded and walked with Zhong Li towards the scene of death, followed by Yan Wei and Yu Xi.

  In the anatomy office, a technician and a very young forensic doctor are squatting next to Liao Feng's body. The technicians are quite experienced, but the movements of the young forensic doctor seem a little rusty, even a little hurried.

  Seeing Lu Ming coming in, the young forensic doctor quickly stood up, took off his gloves nervously and said: "The deceased Liao Feng, 50 years old, was initially determined to have died of coronary heart disease. The cause of death was sudden death. The time of death was ten o'clock. The rest of the tests will not be able to produce results until after the autopsy.”

  “Then the disease died?"Lu Ming asked, he has been used to Liao Feng over the years, and suddenly he is a little unaccustomed to facing this young forensic doctor who has just been separated.

  The young forensic doctor nodded and was about to speak, but was suddenly interrupted by Zhong Li: "Wait a minute, it's not that simple!”

  Everyone looked at Zhong Li at the same time, and saw Zhong Li find a pair of disposable gloves to put on, regardless of whether others agreed or not, he squatted beside Liao Feng's body and began to inspect the body.

  “Vice Captain Lu, who is he?He can't do this, can he?"The young forensic doctor complained.

  “He is a student of Teacher Liao. Teacher Liao died suddenly like this. He may not be able to accept it.So it's okay to let him take a look. Anyway, haven't you preliminarily confirmed that he has died of illness?"Lu Ming's tone was quite a bit of coping, and his eyes did not leave Zhong Li from beginning to end.

  “Okay, let him see, then I'm going to write a report."The forensic doctor shrugged. Since Vice Captain Lu didn't object, what else did he object to?"

  Support the creativity of authors by visiting Royal Road for this novel and more.

  However, just as the medical examiner was about to sign the death report, Zhong Li stood up abruptly and suddenly said loudly: “No, Teacher Liao was killed by someone!”

  This voice was really scary. The living people in the room were taken aback, and the forensic doctor quit immediately: "What nonsense are you talking about!”

  “I said that Teacher Liao was killed.If you don't believe me, let's assume first, if you have a heart attack, what is your first reaction?"Zhong Li's tone was extremely affirmative, his gaze swept across everyone in the room, and finally fell on the forensic doctor's face.

  “The first reaction..." For some reason, when he met Zhong Li's gaze, the forensic doctor felt that his thinking speed immediately slowed down, just like the streets commuting to and from work in the city were blocked.

  “Looking for medicine!"The pleasant female voice sounded, and Yu Xi was the first to react, and then the rest of the people suddenly realized one after another that all patients with heart disease, the first thing to get sick is indeed to find medicine, because a few seconds slower can be fatal.

  “That's right, the first reaction is to find medicine.Teacher Liao has a habit. He likes to put first aid medicine in the right pocket of his white coat, so that it is convenient to take it out.But now the pockets of Teacher Liao's white coat are empty. Do you think it's normal?Will he let the emergency medicine leave where he is used to?"Zhong Li said and took out the side pockets of Liao Feng's white coat, which were indeed empty.

  “This is not enough to prove that he was killed. Maybe he forgot the first aid medicine in the pocket of another white coat."The forensic doctor said.

  “Of course it's more than that. The lesson plan on the table is in a very correct position. The fountain pen is covered, but the cup is broken. There are only a small amount of water marks on the ground. Through the direction of the cup fragments and water marks, as well as the position and direction of Teacher Liao's fall, it can be inferred that he was holding the cup and walking towards the water dispenser, but it was precisely in the process of walking towards the water dispenser that he was knocked out.”

  “Knocked out?”This word greatly exceeded everyone's expectations. Isn't it that he became ill and died?"Why was he knocked out again?

  “Look here."Zhong Li pressed down Liao Feng's right ear, poked the hair behind his right ear, and immediately revealed a small bruise, "The fracture of the mastoid of the right ear is obviously caused by a heavy blow. A heavy blow to this area can easily cause fainting, and it is very hidden and not easy to be discovered. The murderer obviously knows this very well.”

  The forensic doctor's face changed suddenly. He had an inescapable responsibility for missing such an important detail. Fortunately, the death certificate had not been signed yet, otherwise it would be a lot of trouble.

  Lu Ming glared at the forensic doctor and said, “You continue to say, since Teacher Liao was knocked out, what happened to the death symptoms?”

  "Knocking out Teacher Liao is only the first step, and the next step is the deadliest."Zhong Li raised Liao Feng's left hand and pointed to an untraceable small red dot in the dorsal vein and said in a deep voice, "Note that this is a new pinhole. The murderer knew that Teacher Liao had been sick these days and was hanging a hanging bottle every day, causing many pinholes to be left on the blood vessels, so he used these pinholes as a cover and injected a deadly poison into Teacher Liao's blood vessels!"”

  The forensic doctor was finally the first to react this time, and said in a low voice: “Poison that causes arrhythmia!”

  “Yes, most of the causes of sudden death from coronary heart disease are severe arrhythmias. As long as Teacher Liao is injected with poisons that can induce arrhythmias, it can cause sudden death from coronary heart disease and create the illusion of death from the disease.The poisons that can cause arrhythmia are aconitum, fluoroacetamide, oleander, barium chloride, etc. Among them, fluoroacetamide is a rodenticide and was banned a long time ago. Among the other poisons, the most likely is barium chloride.Intravenous bolus injection of barium chloride solution can increase the permeability of Platts fiber to sodium ions, promote the internal flow of sodium ions, while inhibiting the outflow of potassium ions, so that the action potential 4-phase spontaneous de-gradation rate is accelerated...”

  “Make it simple!"Yan Wei couldn't help interrupting. Although he is now the director of the Department of Clinical Medicine, his professional knowledge is seriously regressing. Hearing these headache-inducing things, he will think of those nasty academic geniuses back then.

  "Intravenous bolus injection of barium chloride can avoid gastrointestinal symptoms and directly act on the heart, quickly inducing arrhythmias, which can lead to sudden death from coronary heart disease.In the end, the murderer took the first aid medicine from Teacher Liao's pocket just in case."Zhong Li said.

  “I'll take a blood test now!"The forensic doctor dripped down in a cold sweat and quickly took Liao Feng's blood.

  Yu Xi sorted out everything Zhong Li said in his mind, looked at the surrounding environment again, and suddenly exclaimed: "Doesn't that mean that the murderer is an acquaintance of Liao Feng!"”

  Lu Ming sank his face, a cold light burst out of his tiger eyes, and his tone was cold: "It's not just acquaintances, it's people in this office!”

  Zhong Li nodded and looked down at Teacher Liao's face full of vicissitudes: “This is murder!”
