July 1, 2026 AD, six o'clock in the evening, Ward 371, Banyue City Fifth Neurological Hospital

"Uncle, how do you feel?" Luo Luo entered the ward holding a fruit basket. Xian Han pushed the wheelchair behind Luo Luo. This is a four-person room, and Zhao Dabao's family of three are also in this room.

.But now, there is only Zhao Dabao.

"Your health is okay, thank you, little Luoluo."

"Speaking of which, uncle, why did you first feel uncomfortable or have a stomachache? Have you eaten anything before?"

"Ah, did you ask the uncle this kind of question as soon as you came in? Little Luoluo is really dedicated." The uncle thought seriously for a while and said, "Actually, I felt a little sick in my stomach about four days ago.

I don’t feel very comfortable anymore.”

"Can you be more specific?"

"To be more specific, we are Lao Zhang, Lao Li and Lao Liu who live in the same neighborhood as me. The three of us were playing mahjong the day before. Later, Lao Zhang lost money in gambling and didn't bring enough money with him.

I just used those crayfish to make up the numbers, saying they were caught from mountain spring water, and they tasted pretty good... But I felt sick to my stomach the next morning, thinking I had a bad stomach."

Luo Luo frowned and asked doubtfully: "Isn't it because of the crayfish and not some sashimi?"

Uncle Zhao said with a taboo look on his face: "Hey! Crayfish must not be eaten raw! Otherwise something will happen! Of course they are steamed in a pressure cooker before being eaten! We are also afraid of things like parasites.

Very!"

"What else did uncle eat before crayfish?"

"Before, it was just ordinary rice and scrambled eggs with leeks."

"Didn't you eat fish?"

Uncle Zhao made an exaggerated expression, "Wow, little Luoluo, you will get tired of eating fish every day."

"Hey? Have you eaten any fish or anything in the past few days?"

"I'm trying something new this morning after a long time. After all, it's rare yellowfin tuna. I ate a small piece of meat raw. It's just such a small pleasure." Uncle Zhao scratched his head in embarrassment, "You won't blame me, will you?"

Luoluo shook his head quickly, "No, no."

Now the main sources of transmission are yellowfin tuna and crayfish. For a moment, Luoluo didn't know whether to feel lucky or angry.

Finally, it turned into a helpless sigh, "Okay uncle, I understand, the rest of the hospital will check it out. But uncle, can you contact the other three people?"

"Yes, yes, I'll recite the phone number." Uncle Zhao nodded quickly, and after Luo Luo took out a pen and paper, he read out three mobile phone numbers, "Just call here!"

"Thank you, uncle."

"Actually, I'm the one who really wants to say thank you! I've also heard about my situation from the doctor." The uncle made a circle with his thumb and index finger, "It's said that there is such a big bug in my stomach. It's really...

It scares me to death... I guess during this period, I really don't dare to touch seafood. I'm thinking about selling that seafood shop after a while, and it just so happens that the canteen downstairs of my house is for sale."

"Really, I hope uncle can be happy, haha." Luoluo waved and asked Xianhan to push the wheelchair to the door. He seemed to have thought of something again and turned around and asked, "By the way, uncle, your wife and children have also eaten a small meal."

Lobster?”

"yes."

"What about the tuna?"

"not yet."

"Thank you, uncle."

Luoluo left the ward with a gloomy face, took out his mobile phone and made the first call, but no one answered the call for a long time. He then called the other two people, but no one answered either. He felt a slight

Unhappy, Luoluo immediately shouted, "Go back to the ward quickly!"

Xian Han was stunned and understood, "Ah, I'll go first!"

"Um."

Xian Han spread his legs and strode into the ward, "Uncle, what are the addresses of those three people?"

An hour later, Xiaoyue walked into the office with a tired face. She looked at the tired Luoluo who was leaning on the sofa and said, "The rescue was quite timely. One of them had already crawled down the throat to the base of the tongue. These three people

They are all lonely old people, their children are not around, and no one noticed when they fell ill."

"If it had been a few hours later, we would have had to wait to collect the bodies."

Luoluo frowned upon hearing this, "So, the source of infection is the crayfish."

"Yes, crayfish." Xiaoyue nodded, "And we also discovered a very interesting phenomenon. Silicon-based crystal parasites are resistant to high temperatures and can withstand temperatures up to seven hundred degrees. They can even parasitize another parasite.

When the eggs are not hatched, they are exposed to high temperatures and secrete some special substances at the junction of the exterior and interior to block the high temperature."

Luoluo was shocked, "So, even if you cook the food, you can't kill these parasites?"

"Well, that's what it means."

"Hey, then this, this, this... isn't it going to cause a large-scale crisis and panic!?"

Xiaoyue shook her head, "However, these two parasites will die quickly if they host the host immediately. But the top priority is to find the origin of the crayfish."

"When will Uncle Zhang Shun wake up?" Luo Luo asked, rubbing his eyebrows, "He is the only one who knows where the crayfish is."

"Would you like to stay tomorrow morning? Your ward is still empty."

"sure."

"Where is your follower?"

"I went to the cafeteria for a late-night snack."

July 2, 2026 AD, six o'clock in the morning, Shanhu County.

A car got off the highway and drove into the county town. Although it was not very lively at six o'clock in the morning, there were still many people, such as the adults and aunties who had just gone to the morning market and were walking back. There were also those who had just finished their work.

Students doing morning exercises, and people who have just finished driving and are rushing to school or work.

Xianhan yawned while driving the car, "Senior Luoluo, where are you going next?"

"Biluochun Aquaculture Factory... shouldn't be in the county." Luoluo browsed the map on his mobile phone, "Ah, I found it. I walked through three red and green roads, and then turned right to see their marketing point and warehouse.

.”

"arrive."

After getting off the car, Xianhan asked, "Senior Luoluo, does he need a wheelchair?"

"It's just a few minutes, but it's not necessary."

With that said, Luoluo opened the front door and walked directly into the store. At this time, the clerk was busy placing lobsters one by one in the refrigerated display cabinets. One of the older women said, "Hello, would you like some?

What?"

"Hello, we are coming from Banyue City. We have contacted the owner of this store on the phone before."

"Oh! It's Ms. Luo and Mr. Xian. Come this way, our boss has just arrived." As he said this, the clerk led the two people to the conference room on the second floor. They were wearing suits in the conference room, with a big belly and a small haircut.

A very energetic man is sitting on the sofa, holding a newspaper in his hand and browsing the news.

"Boss, Ms. Luo and Mr. Xian are here."

"Oh! Please sit down, both of you! What would you like to drink?"

"Thank you, Boss Liang, for your kindness. There is no need for this. Time is a bit tight. Let's talk about business." Luoluo slapped his police card on the table and pushed it in front of Boss Liang. "You can tell me what happened.

Not sure, your crayfish may have parasites.”

Boss Liang suddenly stood up, and someone said angrily, "Impossible! This is absolutely impossible!"

"Don't get excited, Boss Liang. I'm not accusing you of a problem with your safety supervision. Rather, the parasite this time is an invasive alien species and is very harmful. We are here to investigate the source of this parasite."

.We believe that your farm must also be a victim.”

"This, that's it." Boss Liang took out a handkerchief to wipe the cold sweat on his forehead, and sat down shakily, "Then, then, is this parasite scary?"

"It's very scary. In experimental conditions, this parasite can withstand temperatures of 700 degrees, and infected people will die within seven days."

Boss Liang's little face turned pale, "Ah this, ah this, no way! Is this really dangerous? I, I eat the crayfish we produce every day!"

Luoluo and Xianhan looked at each other. Luoluo took a deep breath and said, "I suggest you take your employees to the hospital for examination immediately. Can we investigate the warehouses and farms here?"

"Yes, yes!" Boss Liang nodded immediately, turned his head and shouted towards the door, "Xiao An! Xiao An!"

A young girl walked in prancingly, "Uncle, did you call me?"

"Xiao An, these two police comrades are here to do something for us. You must cooperate with their work well and be responsive to requests!"

"Ah good."

Luoluo looked at the girl and asked doubtfully, "Doesn't she need to go check it out?"

"No, no need! This is my niece. She has been allergic to seafood and has been unable to eat this kind of food since she was a child. So, she is the least likely to have problems here."

Luoluo nodded and agreed with him, "But just in case, we will take her for a checkup after the investigation is completed."

"Ah this..."

"Don't worry, we will also conduct inspections after the investigation is completed." Luoluo added.

"Okay, okay, I understand."

Ten minutes later, after Boss Liang simply told Xiao An what happened, Xiao An took Luo Luo and Xian Han to the refrigerated warehouse with a heavy look on his face.
