Cyanide is a colorless gas with a faint bitter almond flavor. However, because of personal genetic problems, there may be forty percent of ordinary people who can't smell that smell.

In some Western hospitals, if you have an incurable disease, or if you have terminal cancer, the patient is in great pain, and you want to be euthanized, where the injection of this cyanide will make the patient die painlessly.

Therefore, when the bodyguard just said that Li Feng died, his expression was not very hideous, indicating that the other party did not know that he was killed by drugs when he died.

As for why that Li Feng is like that now? Ye Chen didn't understand, after hearing what the bodyguard said, he hurriedly went to the ordinary ward, and when he came there, he found that the security guards of the Eastern Hospital were dealing with it there.

Li Feng was killed in a hospital bed, which can be said to be a shame for the East Hospital. However, this kind of thing is simply impossible to prevent in the hospital.

Ye Chen walked over and looked at Li Feng's corpse that had been carried out of the ward, Li Feng's eyes were already blank, and his body had softened. Obviously, it was because of the large amount of that cyanide mixed into the drip potion, and the cyanide entered her body and chemically reacted to death.

Ye Chen knew that in this case, Li Feng was a corpse, a dead person, and naturally he couldn't be saved. However, he didn't expect that in just ten minutes, the other party would be killed.

It is likely that not long after he left the general ward, she was hung and replaced. At the beginning, when Ye Chen was in the ward, he also had a bad feeling. But what exactly, he couldn't figure out.

Outside the ordinary ward, Li Feng's body was sent to the morgue. At this time, Ye Chen met Li Qiuhua and Zhu Mingshan.

Both of them looked bad. However, because the situation of this matter has not yet been announced, except for a small number of people, no one else knows.

"Director Li, what's the situation?" Ye Chen asked.

Seeing Ye Chen ask, after Li Qiuhua and Zhu Mingshan took him aside, Li Qiuhua said: "In Li Feng's blood test just now, it was found that the blood contained a large amount of cyanide. ”

"I don't understand what this cyanide is, it should be a chemical poison, right?" Ye Chen asked. He doesn't really know about those chemicals.

"Yes, since the human cells do not contain chlorophyll, they must ingest food outside the body to maintain body temperature, muscle contraction and stretching, in order to be able to extract energy from food, the human body secretes another enzyme NAD, which combines with hydrogen in food to form NADH2 to replenish energy to the human body. ”

"The used hydrogen and the oxygen breathed in combine to turn into water. Cyanide prevents the exhaled oxygen from combining with hydrogen to turn into water. At the same time, the human body no longer secretes NAD, and the excess oxygen in the human body causes the cells in the body to no longer respire, and eventually leads to heart failure and death. ”

Li Qiuhua explained in detail, and told the principle of cyanide poisoning, Ye Chen didn't understand what green leaves were. However, he didn't expect that Li Feng would be killed like that, because he still wanted the police to find out who was behind her?

"Who is the murderer?" It can be said that this case is a serial killing, and in such an important public place as the Oriental Hospital, it can be seen that the other party is very arrogant.

"I don't know, there is no surveillance video in that general ward, someone changes into a nurse's clothes and goes in, pretending to be inside, and no one notices. In fact, Li Qiuhua also had a feeling of empathy, Ye Chen worked very hard last night to save Li Feng, and later, Li Qiuhua and other medical skills were busy for several hours before they sewed up the injured internal organs in Li Feng's body.

Unexpectedly, not long after Li Feng woke up this afternoon, there was that kind of accident. This is really Li Feng's life, even if Ye Chen saved her, in the end he was murdered because he knew that he shouldn't know.

"Dean Zhu, it seems that the security of your hospital needs to be done better!" Ye Chen said as he looked at Zhu Mingshan, who also had a very bad face on the side.

Last night, after he heard that Li Shengtian had almost had an accident, he was also very worried. I didn't expect that the situation is so strict now.

"This matter implicates the Li family, and they can only rely on the police. However, I will definitely pay more attention to the security issue. Zhu Mingshan said.

Ye Chen returned to Li Shengtian's senior ward, looked at Li Shengtian and said, "That female nurse was killed by a cyanide, it is obvious that the murderer behind it does not want her to continue to live, let you know who wants to harm you?"

Li Yongsheng is naturally very clear about them, and Li Shengtian also knows that many people can't wait for him to die. However, I didn't expect it to be so strict now.

"Doctor Ye, no matter what, it was you who should be thanked the most last night. Li Shengtian looked at him and said gratefully. Because of Ye Chen, he and his son were fine in the end, which belonged to two life-saving graces, which were great favors for them.

"Mr. Li, this is what I should be. However, as you can tell from the incident of the female nurse, you need to be more careful. ”

Now that there is nothing else to do, Ye Chen is not ready to stay, but is about to leave the East Hospital, coming out of the East Hospital, just when he was about to get in the car and leave, he saw a police car emitting an alarm sound of "forcing waves, forcing waves".

Then, seeing that it was Lu Jing and her colleagues, they hurriedly got out of the car.

"Dr. Ye. Ye Chen was about to leave, but was stopped by Lu Jing.

"Officer Lu, is there anything I can do to help you?" Ye Chen asked. Of course, he guessed that it must be because of the female nurse's death.

"So, what's going on with that female nurse Li Feng?" From last night to this afternoon, Lu Jing spent a lot of time here investigating this case.

Actually, she has a lot to gain. For example, she found that Li Feng had a large amount of cash in his closet, with 200,000 yuan in cash, and a bank card with 300,000 yuan in it. Judging from Li Feng's normal income, she naturally doesn't have so much money, and Li Feng's character is crazy about money, if someone didn't suddenly give her a large sum of money, it would definitely not be possible to have so much money.

Therefore, Lu Jing can also be sure that Li Feng received a sum of money before jumping off the building. However, who gave her the money, because Li Feng was not awake at that time, and when she woke up later, she had a problem with her brain, and she couldn't ask clearly at all.

When Lu Jing was just about to go back to the city police station to rest, she didn't expect that on the way, she heard someone call her from the hospital Li Feng had an accident, and she immediately returned to the East Hospital again, and just happened to meet Ye Chen, who was about to leave the hospital.

"I heard that he was poisoned by a large amount of cyanide and died of heart failure. In Li Feng's case, he jumped off the building last night and was rescued by luck, and his heart's endurance was not good. Unexpectedly, he was suddenly poisoned, and naturally he was killed not long after. Ye Chen said. It's just that Ye Chen felt that the police were also a little stupid, knowing that Li Feng was such an important suspect, he didn't let the police focus on guarding.

What Ye Chen didn't expect was that in fact, before he came to the hospital, Lu Jing had been guarded by two policemen there.

However, in the end, because the two policemen relaxed a little, they were pretended to be female nurses to go in to change the dressing, and finally Li Feng was poisoned to death.
