In a mental hospital, Bai Fumei forced me to be her boyfriend

ps: I will read every comment and make selective corrections. Thank you readers for your great subscription.

As for the heroine's question... uh.

The character setting has been decided, but I will try to listen to opinions.

After all, a girl who goes to a mental hospital to find a boyfriend is a bit of a tiger.

A white moonlight like Silly Baitian can't do this kind of thing, ha.

Chapter 123 The main cause of cardiac arrest [1]

Li Xiangbin, Song Ting and others came to the forensic room.

Two corpses were lying on the cold dissecting table.

Song Ting, the anatomical wound has not yet been sutured.

From the perspective of anatomical location, her key investigation site is the heart.

Cardiac arrest.

The problem must lie near the heart.

especially cardiac fibers.

Song Ting said: "In the past two days, our forensic medicine department has conducted a comprehensive investigation on the two corpses."

"From head to toe, nothing is missing."

"Unfortunately, no artificial wounds were found."

"Wang Ze, do you think there is anything wrong here?"

After the words fell, everyone looked at Wang Ze together.

In the conference room, they can freely express their views on the case.

But in the forensic room.

It's hard for them to interrupt.

Including Li Xiangbin.

After all, the profession has a specialization.

There are very few people like Wang Ze who are fully blooming, almost none.

Facing everyone's gaze, Wang Ze didn't immediately answer Song Ting's words.

Instead, they circled around one of the corpses a few times.

This is Yan Jiakui's body.

Judging from the face, the deceased had a ferocious face, his facial muscles contracted, and his pupils dilated.

Obviously frightened performance.

He must have seen something terrible for a few seconds or more before he was alive.

at this point.

Now there is no doubt.

The point is.

A cremator who contacts dead people every day.

A person who is almost immune to so-called supernatural events.

Was scared to death.

It's really strange.

There should be deeper reasons for this.

After observing and thinking for a while, Wang Ze put on his gloves and gently opened the dissection wound.

The blood has basically coagulated.

But still can see a little bit of liquid blood.

"Cotton swabs."

Wang Ze moved closer, staring closely at the wound near the heart.

At the same time, reach out.

Hearing the words, the forensic doctor on the side hurried forward and handed Wang Ze a cotton swab.

Wang Ze took the cotton swab and carefully took a blood sample near the myocardial fibers.

Seeing Wang Ze's actions, Song Ting couldn't help but said, "Do you still want to test for blood drug residues?"

"We have tested it twice and there is no toxic reaction."

"What's more, there was no injection wound near the deceased's heart."

"Even if someone made a move, it shouldn't be the method used."

Wang Ze straightened up, took a close look at the blood on the cotton swab, and said, "Let's not care how the murderer did it."

"Let's first assume that there is something wrong with the blood."

"There is no toxic reaction, so what if it is decomposed?"

Hearing this, Song Ting was taken aback: "Disintegrate?"

"However, the decomposed compounds will become ions."

"How do we determine, hypothetically, what the killer used?"

Wang Ze turned around and came to the testing platform, saying, "That depends on our luck."

"According to the periodic table of elements, start with the most likely, and check one by one."

"Who, take concentrated hydrochloric acid and dilute it to one hundred milliliters."

Forensic doctor: "OK."

Wang Ze: "Inhibitor solution, add sodium citrate and sodium nitrate."

Forensic doctor: "OK."

Watching Wang Ze's testing process, Song Ting fell into deep thought.

Did not speak, just waited quietly.

Although Li Xiangbin and the others couldn't understand, they also knew that they couldn't be disturbed at this moment, so they stood there quietly.

In the entire forensic room, only the busy voices of Wang Ze and the forensic doctor remained.

after an hour.

Wang Ze connected the electrodes.

The value is out.

Song Ting hurried forward.

"This conductivity..."

"Fluoride ion?"

she knows.

What Wang Ze used was a simplified version of ion chromatography.

It can accurately detect the presence of specific ions in a short time.

But this requires a prerequisite.

That is, it is necessary to know in advance what the ion to be detected is.

In other words.

The first thing Wang Ze detected was fluoride ions.

"It appears that our hypothesis was correct, and with luck."

Wang Ze took off his gloves and said.

Song Ting was a little surprised by this result.

It wasn't the test results that surprised her.

It was Wang Ze's judgment.

"How do you know it's fluoride?"

Song Ting said.

Wang Ze: "When I was in the police academy, I happened to read an encyclopedia of inorganic compounds."

"Can cause a person to go into sudden cardiac arrest without a trace."

"At present, there is only one possibility."

At this moment, Li Xiangbin couldn't bear it any longer, and said, "What do you mean? In plain language."

"Is the cause of death determined?"

Wang Xiaotong and the others also looked at Wang Ze with curiosity.

Wang Ze turned around and said, "Hydrogen fluoride."

"Hydrogen fluoride is an inorganic compound."

"Under normal conditions, it is a colorless, toxic gas with a pungent odor, and is very hygroscopic."

Li Xiangbin was taken aback: "Gas?"

"What do you mean? The deceased inhaled poisonous gas during his lifetime?"

Wang Ze shook his head: "I haven't finished yet."

"This hydrogen fluoride is easily soluble in water, and can be infinitely miscible with water to form hydrofluoric acid."

"The focus is on hydrofluoric acid."

"When hydrofluoric acid enters the human body, it will enter the blood circulation and affect the tissues of the whole body."

"¨ "Especially the bones."

"Why bones? Because the toxicity of hydrofluoric acid mainly attacks calcium ions to form insoluble calcium fluoride."

"Specific clinical response, including rapid reduction in blood calcium."

"Thus, causing arrhythmia and even...sudden cardiac arrest."

After listening to Wang Ze's words, the expressions of Li Xiangbin and others changed.

They can probably understand.

But it is the last four words that attract the most attention.

Cardiac arrest.

"The deceased was really poisoned?"

Li Xiangbin was surprised.

Song Ting looked at Wang Ze.

As a senior forensic doctor, she knew that the other party must have something to say.

Wang Ze said: "It is poison, but not oral."

"The murderer obviously understands the toxicity principle and effect of hydrofluoric acid very well."

"Orally, it won't achieve the effect of being scared to death."

"The safest way is to inject fluoride into the blood near the heart to destroy the myocardial fibers."
