"Oh?" Zhuo Yun's expression became serious, "Let's talk about it specifically." ”

If we can know how Tang Yiping died, it will be a major breakthrough for the entire case investigation.

Perhaps, the suspect can be found according to the method of murder.

"Let's sit down first."

Chen Yi moved a chair, and several people sat down casually.

Fang Shuyu said: "Hydrogen fluoride is an inorganic compound, which is a colorless and pungent toxic gas under normal conditions, and has very strong hygroscopicity. ”

"If the human body comes into contact with it, it is easy to burn skin tissues and eyes, and in severe cases, it can lead to sudden death from cardiac arrest."

"The main role is played by the fluoride ions."

"After it penetrates into the human tissues, it will combine calcium ions and magnesium ions in the human body, disrupt the balance of the body, lead to a decrease in calcium and magnesium in the blood, and then produce low blood calcium, low blood magnesium, arrhythmia and convulsions, as well as severe tissue necrosis and metabolic circulatory disorders."

Hearing this, Zhuo Yun spoke: "But isn't Tang Yiping's autopsy result normal?" What's the only thing? Oh yes, the right coronary artery is blocked. ”

Fang Shuyu: "I'm not done yet. ”

"Hydrogen fluoride is soluble in water and miscible to form hydrofluoric acid, which is highly corrosive."

"I mentioned to Chen Yi before that near Tang Yiping's heart ventricle blood vessels, there were slight, suspected traces of corrosion, which I didn't understand before, but now it seems to be clear that it should be a very small amount of hydrofluoric acid."

"If Tang Yiping is affected by hydrofluoric acid for a long time, calcium fluoride and magnesium fluoride will be left in the blood vessels, which will cause blood vessel blockage."

"This is just one of the hazards, after fluoride ions enter the heart blood, they can also combine with hemoglobin to form fluorheme, inhibit succinate dehydrogenase, directly lead to a decrease in oxygenation, and affect cellular respiration."

"In this way, the probability of cardiac arrest is very high compared to normal people."

Zhuo Yun didn't seem to understand, anyway, the result was: Tang Yiping had a heart problem under the action of external forces.

After speaking, Fang Shuyu looked at Chen Yi.

"All that's left is to figure out how this thing got to Tang Yiping's heart."

Chen Yi was thoughtful at the moment, and there was a glint in his eyes: "Acupuncture." ”

"I'm still thinking about how acupuncture kills people, and the key point is here."

"Tang Yiping has been in and out of the Tilt Yuan Hall for two years, and every time he ingests an extremely small amount of hydrofluoric acid, he can't feel it at all in a short period of time."

"And the smell of Chinese medicine in the room is messy, and the amount is so small that it is almost negligible, and he can't smell anything abnormal in the process."

"Over time, there was a problem with the heart."

"Acupuncture?"

Fang Shuyu was surprised, is this the case? No wonder there are no wounds on the body.

Zhuo Yun also had a solemn face: "So Tang Yiping is chronically poisoned, and his heart is overwhelmed and causes sudden arrest?" ”

"Then he was falsely accused of coming to the city bureau, is it a coincidence of time?"

Chen Yi shook his head and slowly stood up: "No, it's not a coincidence. ”

"That call from an unknown black card was the last straw."

"Originally, Tang Yiping was already on the verge of cardiac arrest, if it was this critical moment, apply a strong stimulation ......"

"Theoretically, even a normal person, severe psychological stimulation can lead to cardiac arrest."

"When mechanical stimulation of internal organs, reflexes cause nerve excitation, which inhibits sinus nodes and other forms of pacemakers, and the result is cardiac arrest in the stimulated person."

"And Tang Yiping himself has a heart problem, so the weight of this straw is extremely heavy."

"Although it is not possible to achieve a 100% success rate, we have seen that the murderer has indeed succeeded."

Zhuo Yun felt goosebumps all over his body, and after two years of planning, he killed Tang Yiping in the air with a phone call.

"Chen Yi, you must immediately control everyone in the Tilt Yuan Hall!"

Chen Yi stopped: "Wait, calm down, calm down." ”

"At this time, we must stay calm, and we will go to prison right now."

Zhuo Yun glared: "Do you still have the heart to go to prison?!" ”

Chen Yi said in a deep voice: "Brother Yun, listen to me!" ”

Zhuo Yun's tone was suffocated: "Uh...... Good. ”

Subsequently, the two immediately left the city bureau and rushed to the prison where Tang Yi'an had served his sentence as quickly as possible.

In the face of the arrival of the criminal police of the city bureau, the prison director was very polite, and after learning the other party's intention, he happily called the prison guard who was in charge of the cell that year.

Chen Yi doesn't have many questions, only one: who has the best relationship with Tang Yi'an in eight years in prison.

He got the answer: Feng Shanhai.

At the same time, the prison warden also helped retrieve all the information about Feng Shanhai.

When Chen Yi quickly finished sweeping, his face changed.

"Brother Yun, let Sister Jiang lock Feng Shanhai's location immediately!"

Seeing that Chen Yi rarely became serious, Zhuo Yun didn't ask much, and immediately took out his mobile phone: "Okay, I know." ”

After thanking him, Chen Yi left the prison with the materials.

This clue is really terrible: Feng Shanhai is a Chinese medicine doctor!

The crime is trafficking in drug raw materials.

The motive is to save his sick daughter.

It's Chinese medicine again.

There's definitely a connection.

Feng Shanhai is not in the Tilting Yuan Hall, is the Tilting Yuan Hall just a pretense? took advantage of other opportunities to get close to Tang Yiping?

Could it be that Zhou Zhiyue lied?

There are too many questions at the moment, and we need to check Feng Shanhai to talk about it.

After returning to the city bureau, Chen Yi went straight to Jiang Xiaoxin, and said as he walked: "Sister Jiang, how is the investigation?" ”

Jiang Xiaoxin said: "I haven't found it yet, I'm working hard, I'm afraid it will take time." ”

"The mobile phone number in Feng Shanhai's name has been deactivated, and it is the same as Ma Huiru's situation, I don't know if it is someone else's supplementary card or black card used, and the ID card has no traces of use in recent years, and the bank card is also silent."

"Originally, there was a Chinese medicine hall under his name, but now it shows that it has been cancelled."

"If you want to find someone, you need to visit."

"By the way, he has a daughter in Yangcheng, do you want to call and ask?"

Listening to Jiang Xiaoxin's words, Chen Yi's expression changed slightly: "No, I'll go see her." ”

"Sister Jiang, can you give me all the information about Feng Shanhai's daughter, the more detailed the better, including her medical records."

All the clues were strung together, and he thought of a possibility.

Jiang Xiaoxin: "Okay, no problem, give me half an hour." ”

Half an hour later, Chen Yi took the document handed by the other party, turned around and left.

When he arrived at the door, he stopped Zhuo Yun's footsteps: "Brother Yun, I'll go by myself, you now take someone to visit Qi Jie's hometown in the Tilting Yuan Hall immediately, we need to know the complete information of this person." ”

Zhuo Yun saw that something was wrong with Chen Yi and asked, "Did you think of something?" ”

Chen Yi: "I'm not sure yet, I'll talk about it after checking, and call at any time." ”

Zhuo Yun nodded: "Okay, I know." ”

……

Chen Yi, who was driving on the road, was not in a hurry, he drove very slowly.

In this way, when waiting for the traffic light, you can quickly browse Feng Rui's information.

He directly skipped other irrelevant information, focusing on Feng Rui's medical records.

Acute leukemia, which requires a bone marrow transplant.

Feng Shanhai took the risk of choosing to commit a crime in order to make up for the cost of treatment, and used his professional convenience and way to sell illegal raw materials.

It's a pity that he was arrested quickly.

The law stipulates that the trafficking of drug raw materials is punishable by up to three years in prison, criminal detention or public surveillance, and a fine, but Feng Shanhai was in a hurry to use the money, and the amount involved was very large, and he was finally sentenced to eight years in prison.

Feng Shanhai was the first to be released from prison, and Tang Yi'an was released from prison soon after.

Strangely, Feng Shanhai's imprisonment did not affect Feng Rui's treatment, she quickly raised money half a year later, and the operation was successful.

Donation?

State subsidy?

Just ask and you'll know.

After putting down the information, Chen Yi stepped on the accelerator, sped up, and finally slowly stopped at the door of a clothing store in Yangcheng.

Feng Rui is the owner of this clothing store.

When Chen Yi got out of the car and came to the door to look inside, he saw Feng Rui, who was over thirty, sitting there playing with his mobile phone.

Now there are no guests.

Chen Yi walked in.

Seeing that a guest came to the door, Feng Rui subconsciously raised her head, put down her mobile phone and got up, with a smile on her face.

"Hello."

Looking at Feng Rui in front of him, Chen Yi was slightly silent before speaking: "Can you tell me where Feng Shanhai is?" ”

When Leng Buding heard this name, the smile on Feng Rui's face froze immediately, and his brows furrowed: "Who are you?" ”

Chen Yi: "Criminal police." ”

Feng Rui's face changed slightly, she didn't speak, and sat down silently.

Chen Yi repeated: "Can you tell me where Feng Shanhai is?" ”

Feng Rui took a deep breath and shook his head: "I don't know." ”

Chen Yi: "You are his daughter, don't you know?" ”

Feng Rui snorted coldly: "What's wrong with my daughter?" Does my daughter have to know? ”

Chen Yi didn't continue to ask, and asked the second question: "Where did you get the money for your treatment back then?" ”

"You can't lie about this, we can find out."

Feng Rui was quiet for a moment and said, "A sister gave it." ”

Chen Yi: "Zhou Zhiyue? ”

"Huh?" Feng Rui looked up suddenly, a little surprised: "How do you know?" ”

Chen Yi continued to speak: "So, not long after your father was imprisoned, Zhou Zhiyue suddenly came to the door to find you and helped you pay off all the treatment costs. ”

"Really?"

Feng Rui didn't answer, and bowed her head again.

Chen Yi's brain is running rapidly at the moment.

After being imprisoned, Feng Shanhai and Tang Yi'an quickly became good friends because they could talk.

After learning about Feng Shanhai's daughter's plight, Tang Yi'an said that he could help, and took the opportunity of visiting the prison to seek Zhou Zhiyue's help.

So, Feng Rui recovered.

Feng Shanhai, who had no worries, was grateful to Tang Yi'an, and the relationship between the two went further, and their friendship with each other was extremely strong.

And then what?

What happened to the two after they were released from prison?

"Do you know Tang Yi'an?" Chen Yi suddenly spoke.

Feng Rui's shoulders shook and replied, "I don't know." ”

Chen Yi: "Are you sure?" He and your father should be excellent friends. ”

Feng Rui shook his head: "I'm sorry, I really don't know, I've never heard of it." ”

Chen Yi didn't want to force the other party, but in order to thoroughly investigate the case, he stepped forward and bent over, stared at Feng Rui and said, "Is Tang Yi'an really dead?" ”
