About a minute later, Chiba ran over with the bag of leftover bread that had been opened. "The bread is here, but what do you need these things for......" "Make a noise," Gregory commanded as he simply took the bread from Chiba's hand and crushed it as he took the crumbs from it. "I'm sure you're pretty good at making imaginative sounds – I'm just going to cause epilepsy." (Author: One of the ways epilepsy is triggered is strange sounds)

"Hmm......" Qian Yu thought for a moment and took a deep breath. Lulu - (flick tongue)"

Before he could finish exhaling the air in his lungs, a louder "gurgling" sound suddenly sounded from the side.

Gregory quickly let go of the slice of bread in his hand, and then looked at the source of the sound together with Qian Yu, who had already reacted and raised his head again.

"Ahh "Pigeons?"

In front of him, a large flock of pigeons obediently lined up on the crumbs of bread sprinkled by Gregory, eating the bread quietly.

"Well, that's probably a reflex they've learned, and someone will feed them bread here every day." Grigory nodded. "But you see, even though they've even developed this reflex, there's not a lot of pigeon droppings here – or rather, I guess that's why they feed the pigeons."

"What do you mean?" Qian Yu was stunned.

"Don't you know?" Gregory glanced at him, then looked back at the pigeons. "The digestive system of the pigeon is too short, so it belongs to the batch with relatively low absorption efficiency, and the nutritional value is very high. As long as a simple fermentation is carried out to decompose uric acid, it is a very high-quality and inexpensive fertilizer. ”

"Really?" Chiba's eyes widened and she looked at the pigeons carefully.

"Fake," Gregory said immediately. "This group of people only feed the pigeons so that they can abuse themselves every day and make themselves tired of cleaning up the pigeon droppings."

"Huh?" Qian Yu was completely stunned at this moment. "Self-...... Masochism? ”

"Of course it's true," the corners of Gregory's mouth twitched. "Don't you see their flower room? That's their fertilizer - come with me, they'll get their hazmat suits dirty in a little while. ”

Three minutes later, in the flower room.

"Considering the scraper, I think this is it," Grigory nodded, looking at the bucket with a scraper on the lid that had been dragged out by Chiha. "Open it and take a look."

“Roger.” Qian Yu nodded, took off the lid of the bucket with the scraper, and looked inside. "Ah...... I think that's ...... It looks like cement, but it's certainly not cement. ”

In front of him, a large amount of gray mud was soaked in the liquid - apparently pigeon droppings were fermenting.

"It's full of pigeon droppings, a great place to stay for Cryptococcus neoformans." Grigory nodded, clearly pleased with the discovery. "The fungus enters the brain through the sphenoid sinus, where it causes euphoria, blindness, and uncontrollable pain."

"So...... Is that D still saved? "Chiba took out a sampling bottle and took a little pigeon droppings.

"Amphotericin B plus flucytosine, he'll be fine." Grigory nodded. "Contact them and tell them what happened."

"By the way, if it is said that it enters the brain through the sphenoid sinus, can I understand that D has inhaled Cryptococcus neoformans?" Qian Yu asked suddenly.

"So to speak." Grigory nodded.

"In other words, D must have opened the barrel and therefore exposed to a high density of Cryptococcus neoformans, so he was tricked? Otherwise, this is too contagious. ”

"......" Grigory narrowed his eyes slightly - he had indeed ignored the problem before, and theoretically contracting Cryptococcus neoformans in this way was a very unlikely event for a person who had not been in contact with a pigeon before and had only come to check it once.

"Do you have any other clues you can provide?" A few seconds later, Grigory asked.

"I don't have any ideas," Qian Yu said. "I ...... If I have to say anything, I'm just your-ah!! ”

As he said this, something suddenly hit the window on the front of the suit.

"Oh!" Almost at the same time, the same thing happened to Gregory.

The next moment, the settlement of the auxiliary units gave the answer - a stream of water sprayed onto their protective suits.

"Damn, they never thought it would squirt themselves, did they?" Grigory wiped the water off the window and complained. But the next moment, he thought of something. "Hey, has the water been tested here?"

"Yes, they've already taken water from the flower house's water supply system before." Qian Yu nodded.

"Take it again, there may be some pathogens that haven't been detected before." Grigory finally sighed and nodded. "We'll go back to the hospital – or you can just take off your suit here and go straight back to your room to rest."

"I still won't go back to the hospital, and Gray Yuan told me that they have been released and are in the car on the way back."

…………

A few hours later

"So, is it because I feed the pigeons?" When A=B heard the doctor's statement, the expression on his face was quite complicated.

"Yes, but now everything is in the past. Both your Legionnaires' disease and meningitis have been effectively treated with symptomatic medications – your Legionella symptoms have subsided, and the euphoric and blindness symptoms of Cryptococcal neoformanism meningitis have disappeared. After taking the medicine for about five months, you can be completely cured. The doctor nodded, reassuring. The disease is generally very easily misdiagnosed, so it takes a long time to treat, but at least it doesn't have the worst possible outcome. ”

Of course, despite the doctor's reassurance, he also knew that Cryptococcus neoformans meningitis was not such an easy condition to treat—in the previous treatment, he had been given some antibiotics for too long, which could lead to eventually complications and neurological sequelae.

Of course, it's better than dying, isn't it?

"At least my eyesight has returned," B said with a happy expression for the rest of his life. "It's really scary, especially when the nurses tell me that what I'm seeing isn't real, it's just an imaginary illusion."

Just as he was thinking like this, the alarm bell suddenly rang - from the isolation cell of D, who had the earliest illness.

"What's going on?" B also realized that something was wrong. "Did something happen?"

"I don't know." The doctor frowned.

At this moment, there were already well-dressed medical staff running into D's isolation room.

"Tachycardia! The waveform is wide and varied, as if it were ventricular tachycardia! ”

At the same time, in the testing room, Grigory looked at the results of the cultivation in front of him with a gloomy face.

Cryptococcus: negative
