Bro, you are a policeman, not a thug.

"Even if you can run away by yourself, you still have to leave traces, right?"

Xiao Mu's expression was wrong, he really couldn't understand it.

Then he returned to the crime scene and then to the small square.

We walked this road back and forth five times and continued our investigation until night.

"Get some rest."

Zhao Xiaotang stopped Xiao Mu, who was about to continue the investigation, and said, "Eat something."

The two of them sat on the roadside and absentmindedly ate fast food.

"If this continues, we will soon be exhausted."

Zhao Xiaotang put down the snack box and complained with a smile.

"Actually, dogs are not as tired as humans."

Xiao Mu smiled and said, "The dog doesn't have to work."

Zhao Xiaotang felt a little pain in his balls instantly.

This damn Jing is telling the truth!

"We have been investigating for three days, and you can also investigate for an afternoon."

Zhao Xiaotang sighed, "It seems that there is really no problem with this road."

Xiao Mu shook his head, "Maybe it's not the ground."

"Not the ground?"

Zhao Xiaotang was confused for a moment, "Is it the sky?"

This situation has not happened before.

"It shouldn't be heaven."

Xiao Mu looked at the night sky, "It was at night when the crime occurred. It is extremely difficult to accurately throw something from the air to the human body, let alone enter the brain... Huh?"

Suddenly he remembered something, "I remember you told me about brain-eating insects?"

"right."

Zhao Xiaotang was surprised, "What's wrong?"

"Brain-eating bugs enter the brain through the olfactory system."

Xiao Mu's eyes flashed, "The nose, nasal nerves, blood vessel pathways... is it possible that the unknown thing also used this method?"

"No, otherwise the forensic doctor wouldn't be able to spot it."

Zhao Xiaotang frowned.

“Just because you can’t see it, it’s more likely to happen.”

Xiao Mu stood up instantly, "Let's go and see the victim's body."

Zhao Xiaotang:......

I got up and accompanied my little brother to the forensic identification center.

He was also curious about what Xiao Mu had thought of!

…

Anatomy room.

"There's a problem."

Xiao Mu looked at the forensic doctor, "Apart from bugs, is there nothing else that can control living things?"

"this……"

The forensic doctor fell into deep thought and tried to remember.

"I mean, it's something that we might not be able to see, but it can be airborne."

Xiao Mu gave a hint.

"bacteria?"

The forensic doctor's eyes lit up, "No, it's not bacteria, it's fungus. There is indeed a fungus that can control living things, zombie fungus!"

This fungus is so terrifying that it can parasitize all arthropods.

You heard it right, all arthropods.

For example, the well-known Cordyceps sinensis is parasitized by this type of fungus.

For example, there is a fungus, Ophiocordyceps hemiformis, which can release more than 30,000 spores per second.

If one of these spores lands in the right place, say, on an ant.

The spores penetrate the ant's exoskeleton and hijack the ant's body in ways that are unimaginable to ordinary people.

Make the ant a living puppet that listens to its commands!

When the forensic doctor mentioned this fungus, Xiao Mu and Zhao Xiaotang looked at each other and their expressions changed.

Isn't this basically similar to the case at hand?

"Can fungi control the human body?" Xiao Mu continued to ask.

"Basically impossible."

The forensic doctor shook his head, "Humans are not arthropods, but chordates. This fungus is ineffective against humans and cannot survive even if it enters the body."

"I meant something like that."

Xiao Mu frowned, "It doesn't necessarily have to be spores. Could it be something artificially made, synthesized, or cultivated?"

"this……"

The forensic doctor was stunned for a while and smiled bitterly, "You think too highly of me. Although I am a forensic doctor, I don't know everything. I once dissected a corpse like this. The victim was obviously poisoned, but we forensic doctors don't do autopsies at all. We couldn’t figure out what kind of poison it was, so we even called our teacher, but he didn’t even see it. Finally, he called in a big shot in chemistry and found out that it was a synthetic chemical poison!”

When it comes to poison, do the buddies who know chemistry all laugh?

In any chemical research project, there may be a poison that kills people, or even several or dozens of poisons.

It would be scary if people who play chemistry go astray.

You will see what the real high-end game is!

Xiao Mu nodded and did not embarrass the forensic doctor again.

But I have guessed a possibility.

There should be such a thing.

If so, it may lead to another possibility.

Cross-border crime!

I have already talked about the ‘horror’ of cross-border crime.

You repeatedly jump around the blind spots of your police knowledge, and you still can't find them.

Only in this case can the police find no clues.

Xiao Mu could think of it, and so did Zhao Xiaotang.

Their faces all showed expressions of pain in their balls and tight anus.

"The last question is the one I just asked and you didn't give an answer to."

Xiao Mu stared at the forensic doctor, "If there is such a thing, can it be spread through the air, and can it be detected after it enters the human body?"

The forensic doctor was silent for half a minute and nodded, "If it is bacteria or fungi, it is extremely difficult to find, but it is not traceable, because it requires a process and path to enter the human body. But we have not found this path, the unknown Things appear directly in the brain, and that’s what we don’t understand.”

To put it bluntly: people eat pigs, pigs eat feed, but some people don't eat pigs because it's too troublesome, and eat feed directly. Can you understand it?

Even the forensic doctor can't understand it, how can you let two criminal investigation police understand it?

Xiao Mu and Zhao Xiaotang just left.

After leaving the identification center, the two said in unison: "Cross-border crime!"

"What should I do?"

Zhao Xiaotang looked tired, "Even if I want to call someone, I don't know who to call."

To treat a disease, you have to prescribe the right medicine.

You don't know whether this unknown thing is chemistry, biology, or other sciences!

"It doesn't matter if you don't know."

Xiao Mu's eyes flashed coldly, "Since that kind of thing appeared, there should be residue now."

Hasn't he investigated the scene five or six times?

That's right, but he investigated things related to criminal investigation.

If that thing is 'spores', how could he pay attention to it?

Back to the scene.

Xiao Mu opened the Eye of Insight again and started to check from the small square.

This time, he didn't look for any traces.

Instead, he focused on tiny dust, particles, and dust.

At the same time, he activated the unparalleled smell.

He wanted to see if there were any special bacteria.

Some bacteria can produce special smells that can be captured by the sense of smell.

When Xiao Mu surveyed the small square, he finally walked to the fountain.

Suddenly, his eyes were fixed on a crack in the wall of the pool.

He saw a few particles of "dust" and smelled the smell of special bacteria.

Xiao Mu's eyes lit up instantly.

Found it!
