He didn't expect that it would be very normal for someone to perform a puncture injection at this position.

According to Su Xuezhi's understanding, it should be many years later, when the heart surgery developed to the point where it was possible to implant a pacemaker, in order to avoid a complication called squeeze syndrome, cardiology doctors began the general practice of transaxial venous puncture, and then promoted it to puncture in infants and young children.

"I understand!" The British changed their previous arrogant attitude and expressed their expressions very excited.

"The murderer passed through the armpit vein and injected high concentrations of ethanol into the body of the deceased, and then pushed the person into the water, causing the illusion of drowning! But..."

He paused.

"There is another suspicious point. If the deceased is awake, of course he will not be allowed to mercy by the murderer. But if the deceased is unconscious at the time, for example, being knocked out and having no scars for external examination..."

"Yitu (Ether)." said Su Xuezhi.

"Since the murderer has mastered this method of injection, he must also know about Yitu."

"You are right! First, use it to make him unconscious, just like having surgery, then inject alcohol, after a few injections, wait for the dose to be enough, and then push him into the water!"

"God, it's almost! If it weren't for you, it would be a perfect crime!"

Mr. Lawen looked at Su Xuezhi, his two gray eyes shining.

"Young man, if you go to commit a crime, I bet it will be a nightmare for everyone! Now let's see if the dead have left traces of inhalation."

He seemed excited and impatient.

Su Xuezhi carefully examined the deceased's mouth and nose without missing any acupuncture marks. On the surface of the nasal membrane inside the nostril, traces of local rupture of capillaries were found, and a small fiber-like foreign substance was obtained in the nasal hair. After magnification with a microscope, it was suspected that it was a residue of a sesame material.

At this point, Su Xuezhi completed today's re-examination.

This re-examination completely overturned yesterday's conclusion.

Su Xuezhi turned to He Hanzhu and provided his own opinion.

Fu Jian died in a carefully designed murder.

The murderer used a handkerchief sprinkled with a handkerchief to make Fu Jiansheng faint, leaving him in a state of brief anesthesia, then injected a large dose of alcohol, and then sent someone to the water.

When Fu Jiansheng encounters cold water, he may stimulate his awakening, struggle to survive, or have not woken up, which has little impact on the result. Even when he wakes up, under the influence of alcohol, he is unable to save himself and drowns quickly, causing death.

"I can only say that one of the directions of the murderer's investigation is likely to understand medicine..."

The door of the morgue was pushed open suddenly, and Mrs. Fu rushed in, her eyes red, and she looked at the body of her son who had been covered with white cloth. After a moment, she let out a sharp cry: "Fu Mingcheng, you must die well-"
