At this moment, Zhou Yan didn't know what was wrong with his brain circuit. He suddenly thought of a very wonderful, simple experiment that many people even think of when they were young.

This experiment is really ridiculous, so most people stop thinking when they grow up.

That is...if air is injected into a person's body, will the person die?

Lin Xi was also thinking at this moment, but when she saw Zhou Yan holding the book, she suddenly became stunned for a moment, and then stood there...

"What's wrong with you...?"

Zhou Yan raised his head and looked at Lin Xi: "Uh, boss, what would you think if you had a pipe of air into someone's body?"

Lin Xi hesitated for a while when he heard this question: "This... I don't know much. You should ask the forensic doctor for this kind of thing. Alas, you can always make a few words about something like this that has something to do with medicine?"

"I'm not good at my brain today, it doesn't matter. Call the doctor!"

Lin Xi didn't delay it, so he took out his cell phone and called the forensic doctor.

The phone was quickly answered. After Lin Xi asked the question, the forensic doctor's answer was also very straightforward.

"It's okay if you don't have less, but if you don't have too much, you will die..."

After Lin Xi's questioning, the forensic doctor explained in detail.

There are two types of air after entering the blood vessels.

One is intermittent (slow) injection, and the other is continuous (fast) injection.

The former is relatively safe. If you are lucky, there will be no problem about 10 ml, but if you exceed 30 ml, it may cause air embolism. If it is blocked on important blood vessels, it may cause death, but the probability is not high.

The latter is very dangerous. For example, if you take a syringe tube and quickly and fiercely penetrate the patient's body, the mortality rate is extremely high.

After 20-40 ml of air are continuously injected into adults, 90% of them will form emboli in the major arteries. If it is at the entrance of the coronary artery or pulmonary artery, people will die on the spot. Even if they are blocked in other places, people will most likely die.

And when a child is about 10 ml, his life is in danger.

Zhou Yan's expression became heavier and he finally took the phone over and asked himself.

"So if a large amount of air is injected into death, will there be something different about the blood test?"

"No, it's hard for air to dissolve directly in the blood. The cause of death from air embolism is not a chemical change, but a simple physical death, which is just a blockage." The forensic doctor was still talking slowly.

"Then... that person died and the blood test could not detect any abnormalities. Isn't this a fucking crime?!"

"No, people who die from air embolism usually have pinholes on their bodies."

"What if it's someone with a lot of pinholes on his body, such as an addict... Yes, I mean [Li Dabo]'s body!"

"That can be detected, but it's just a bit troublesome, because air embolism will appear in the blood vessels. You can find it by just cutting the body open."

"Then you should check it out quickly!" Zhou Yan shouted.

The forensic doctor was also not vague: "Isn't this a check? The body found in the early morning was confirmed in the morning. You asked me to cut the body now, and find bubbles in each blood vessel. How could it be so fast!"

"Uh... I'm sorry, you've worked hard." Zhou Yan apologized, and then hung up the phone.

Lin Xi looked at Zhou Yan: "So... do you suspect that Chen Keke injected air into the body of the deceased while interviewing us last night?"
