"Little Xu is here." Sister Liu, who was in charge of cleaning on the ship, greeted Xu Anran warmly. "Yes, Sister Liu, good morning." After Xu Anran and her group arrived, because she claimed to have some medical knowledge when registering, she was assigned to work as an assistant under Dr. Luo, earning 10 points per day, which could be used to redeem items.

Because Xu Anran needed to come to the ship to work every day, Luo Xi stayed on their own ship to take care of the two little ones. Although the security was quite good now that they were traveling on official ships, it was still difficult to completely eliminate theft and robbery that lurked in the shadows, so they had to leave someone on the ship to guard it.

On this day, a patient with a pale face and a limp body was welcomed into the originally quiet ward.

He looked as if some invisible force had drained all the strength from his body, leaving him extremely weak. When the doctor inquired about his condition with concern, he seemed to have a fishbone stuck in his throat, wanting to speak but unable to utter a sound.

Seeing this, Dr. Luo turned his gaze to the person who had brought him to the hospital, hoping to get some answers from them.

The person who brought the patient in looked anxious and confused, saying that the patient had been like this since waking up that morning, without any prior warning. Upon hearing this, Dr. Luo immediately began a thorough and meticulous examination of the patient. After careful examination, he found no obvious signs of external injury.

So Dr. Luo turned to the man who had just spoken and asked about the patient's diet the previous night. The man replied that the food they had eaten the previous night consisted of wheat bran cakes provided by the ship and fresh fish caught from the sea.

Hearing this, another person who had been standing next to the patient added, "After dinner last night, he still felt a little hungry, so he went back into the water to catch fish. He caught a fish that looked like a catfish. He thought it was too much trouble to start a fire and cook, so he simply made it into sashimi and ate it."

After listening to the story, Dr. Liu suspected that the patient had an upset stomach, possibly caused by parasites. He then instructed Xu Anran to retrieve a bottle of emetic and a bottle of insecticide from the cabinet behind her.

Xu Anran poured the emetic into the man's mouth, and soon he reacted, immediately running towards the sink. Because both Dr. Liu and Xu Anran were wearing masks and gloves, they were unaffected by the stench of the man's vomit. However, the person who had accompanied him felt unbearably nauseous, as the stench was like a mixture of rotting, decaying flesh and a fishy smell, making them want to vomit.

After a while, the man finished vomiting like a storm. They rushed over to check and found many tiny, translucent white worms mixed in with the disgusting vomit.

These insects were as thin as hair; if they weren't wriggling, they would be almost undetectable. Dr. Liu quickly took out test tubes and clamps, carefully picked out a few and collected them as samples, then rinsed these disgusting creatures away with clean water until they disappeared without a trace.

Xu Anran also took out disinfectant and insecticide, spraying the area and surrounding area many times. Dr. Liu handed the prescribed insecticide to the man, explaining in detail how to take it and asking him to come back for a follow-up examination in two days.

After the man left, Dr. Liu immediately wrote a report on his condition, preparing to submit it to his superiors. He was deeply worried, fearing that many similar cases would occur, and urgently hoped that an announcement would be issued to raise awareness about the parasite problem.

However, unbeknownst to them, danger had already crept up on them like a ghost. As the man vomited, several worms splashed out, one of which, like a cunning venomous snake, had already slithered into Xu Anran's shoe, while the others crawled onto Doctor Liu and the people around them.

They are so small and inconspicuous that disinfectants and pesticides have no effect on them. No one knows that they are the real terror, more so than floods...

After work, she went to the redemption counter to exchange her points accumulated over the past two weeks for various items. She first redeemed some vegetables and a few bran cakes. Although they weren't lacking in food, not redeeming anything would inevitably arouse suspicion. Afterward, she selected some daily necessities and went home.

On the ship, there were small boats specifically for commuting people to and from work, costing one point for each round trip. She boarded a small boat and, in the afterglow of the setting sun, was taken home.

By this time, the sun was already setting in the west, and the colorful clouds on the horizon were like a magnificent painting. She walked into the cabin in a cheerful mood.

The aroma of food wafted from the cabin. She went in and saw the table laden with prepared dishes, waiting for her to return so they could eat together.

The food on the table was all collected before the apocalypse, and it was still warm when Luo Xi took it out of her space. Because there were other ships around, they dared not eat food with strong flavors, so they ate some light home-style dishes: steaming hot buns, fragrant wontons, and plump, juicy dumplings, along with several home-style side dishes: eggplant with minced meat, which was crystal clear; scrambled eggs with tomatoes, which were red and yellow; and crab roe tofu, which was fresh, tender, and smooth, making one's mouth water.

Compared to those around them who could only eat dry biscuits and fish of varying varieties every day, and for whom even eating vegetables was a luxury, this was a delicacy they could only dream of.

After dinner, Xu Anran happily gathered everyone together and, as if by magic, produced two train tickets—one for two months ahead and the other for one month. Everyone was overjoyed to see the tickets. Luo Xi asked curiously, "Sister Anran, where did you find these?"

"I found it by chance in the corner of the second floor of the ship's cabin when I went to help Dr. Liu deliver medicine to the patients today." She neatly laid all the tickets on the table.

Xiao Feng curiously peered at the tickets and asked in confusion, "But even with these two, we still don't have four identical ones."

“It’s okay, we’ll treat these as a safety net for now. We still have time, we’ll definitely find something,” Xu Anran said.

Luo Xi chimed in, "I've been observing these past few days, and several people look like passengers. I'll test them out tomorrow." Xu Anran reminded her to be careful.

Xiao Yue, who had been standing quietly to the side, listened intently to their conversation. Since boarding the ship, Xiao Yue had been like a wounded fawn, rarely speaking except for her crying on the first day. Xu Anran was helpless and could only resign herself to the status quo.

After everyone finished their conversation, night had fallen, and it was getting late, so they washed up and went to bed.

However, Xu Anran unexpectedly had a dream that night, even though it wasn't time for her to actively have a precognitive dream.
