Yan Hua frowned and studied the parasites, and quietly scanned the passers-by.

At this glance, her pupils suddenly shrank.

On scanning, the walking people look like bugs stacked on top of each other.

In Yan Hua's eyes, the fat layer of the people who walked in front of her was full of dense insects.

Including in the brain.

She scanned a dozen people in a row.

Imaging can definitely scare people with dense phobias to death.

The matter is so serious, but these people all look like no one, painless, and go about their work as usual.

This......

She couldn't help but glance at the bucket again.

The insects inside are very active, entwined and chasing each other, and sometimes they will float together in one direction, like a school of fish, and like a fine red silk thread.

However, looking at such a harmless parasite, Yan Hua knew its reproductive ability.

There is such an experiment in the interest experiment class in elementary school.

A single red filaria was isolated and observed daily under a microscope.

In cases of extreme hunger, the red filaria will bite itself off and split it into two parts.

Over the next day, the red filaria in the petri dish will produce hundreds or thousands of eggs.

The adult worm eats some of the eggs to feed themselves, and the remaining eggs hatch into larvae within a day.

The larval growth cycle is three days.

After three days, the dish will be filled with adult worms, which can also cause the dish to be too crowded.

At this time, red filaria worms will devour each other, fighting like Gu worms, competing for living space.

At the end of the fight, the adults who survive will lay eggs again.

Then continue to the previous cycle.

This is the state in a petri dish.

It's not much different from being in a well.

However, once the heartworm is stimulated, such as boiling water stimulation, freezing stimulation, and the environment changes too much, it will cause the heartworm to be uneasy.

When the red heartworm is stimulated, it will eat more frantically and lay eggs.

Therefore, after being used as food in the human body, the adult worms that lay eggs will die quickly.

But those eggs hatch quickly, and before being excreted, the larvae burrow out of the stomach and intestines, follow the bloodstream into the capillaries, and eventually into the fat layer to eat.

They don't love animal offal, but rather like to eat fat.

Very fat people will lose weight very quickly after being parasitized.

Until the fat on the body is eaten up.

In order to survive, the army of red filarials chooses muscles and internal organs, and even bone marrow and brains.

This process is slow, because when there is enough food, the red filaria will not easily let the parasite die.

At present, the people of this town are in the early stage of being parasitized.

When the red filaria was first discovered, it was disgusted.

It was able to reappear in the stars, brought back by the expedition of the Epoch Jump.

The environment in which they went was very bad, and they ran out of food and drank the water of the river to explore the target, and they were so hit.

Fortunately, after people come back, they have to do a body scan and data collection first.

All of the survivors of the expedition were parasitized by this terrible parasite.

It took a lot of effort to expel the parasitism, and the sample was left behind.

When it was sent to the laboratory for cultivation, researchers were amazed at its reproductive ability and medicinal value.

Yes, it has medicinal properties.

People who are parasitized by red filaria will not feel pain at first, but at most they will occasionally feel itchy skin, and the flesh will feel as if something is crawling, and if you pay close attention, that feeling will disappear again.

It's like a nerve beating, fleeting, and difficult for the parasite to detect.

By the time it is detected, it is by the time they have spread all over the parasite, and the fat has been eaten up, and it has moved on to gnaw at the muscles and internal organs.

The slight pain that is like thousands of ants burrowing under the skin and biting will continue until the parasite is devoured and the flesh is gone, leaving only a dry corpse with skin and bones.

It was real skin and bones, except for the skin and bones and nerves, all other tissues were eaten very cleanly, and the death was very horrible.

But until then, the red heartworm, in order to enjoy the delicacy, will not allow the parasite to die.

They also die quickly after leaving the host.

With the exception of those eggs that are excreted, the red filaria that breeds in the human body cannot survive in the outside world.

This is also the reason why they do not let the parasites die quickly.

After research, their saliva and a layer of mucus secreted on their bodies are rare anesthetics and antibiotics.

Yan Hua glanced at the insects in the bucket again.

There is no high-tech extraction technology in this world, and she can't use these raw materials.

No, wait!

Just because you can't extract pharmaceuticals doesn't mean you can't recover raw materials.

Yan Hua suddenly remembered the function of 9001 to recycle rags, and the corners of his lips hooked slightly.

Regardless of whether these bugs are here as a natural disaster or a man-made disaster, these can be her recycling materials before it spreads widely.

Yan Hua chose a koi skin for the 9001 little secretary and put it in the bucket.

"You're already a mature system, you should learn to catch red filariads yourself and recycle them."

9001 Little Koi: ......

The cute little koi swims around the bucket, and the red filaria in the bucket disappears completely.

Yan Hua pointed to the well, and the 9001 little koi carp jumped into the well.

In about half an hour, the voice of the 9001 little koi came into Yan Hua's brain.

"Lord Silver, the bottom of the well leads in all directions, and there is an underground river, which can lead to the location of other wells."

Yan Hua knew that it was no wonder that there were red filaments in every well.

The 9001 little koi jumped into the well and found that the red filaria below was simply infested, and it was a little sad about this recycling work.

To recover so many red filariads, this is not a small amount of work.

After 9001 Little Koi contacted Yan Hua and explained that it would take time, Yan Hua simply found a broken temple to live in.

It took two days to clean up the underground river.

It can also be seen that the scope of this underground river must be not small.

When Yan Hua was waiting for 9001 to work, he was also thinking about how to save the people here?

In general, in areas where there is a large outbreak of this parasite, there should be the presence of another pathogenic bacterium that inhibits its spread.

But in the process of scanning just now, Yan Hua didn't find it.

Thinking of this, when Yan Hua asked the 9001 little koi to recycle the red filaria, he also paid attention to the existence of this pathogenic bacteria.

Not to mention, 9001 is really capable of doing a lot after having an entity.

While swimming through the underground rivers in the area, it noticed that a connected tributary was clean, and not a single red filaria wanted to swim in that direction.

The eyes of the 9001 little koi fish lit up, and they scanned it in that direction, and found a thick layer of living bacteria on the stone wall over there.

A piece of green, with a faint white, mottled on the stone and swaying with the current.

Got it!
