She spent several nights installing the surveillance cameras she bought and then stopped going out. She spent her days either exercising or checking the footage on her laptop.

As December drew closer, Xu Anran grew increasingly anxious. Finally, on November 25th, she saw on the security camera that someone was coughing incessantly and struggling to breathe at the entrance of the second building behind hers, and was taken away by ambulance. She knew that the virus outbreak in the neighborhood had begun.

That evening, she closely monitored all the surveillance footage, hoping to see the ticket appear. But she was disappointed; the ticket never appeared in her sight, and the number of people infected with the virus continued to rise.

Xu Anran felt she couldn't just rely on the surveillance footage anymore, so she decided to go downstairs to search every night when no one was around.

At midnight that night, she put on her protective suit, sprayed herself with disinfectant alcohol, and donned a hat and goggles, completely wrapped up from head to toe, before heading downstairs. She first searched her own building, carefully checking every corner, from stairwells and elevators to the rooftop and stairwell entrances. Then she checked the community's garden pavilion. She searched for two more days, having basically checked the entire community, but still found nothing.

Today is November 30th, the last day. If we still can't find it today, we'll have to give up and leave.

At 5 p.m., while reviewing the surveillance footage again, she finally found the ticket.

In the building where the first patient appeared, something was faintly glowing on the milk delivery box at the building entrance. It wasn't very noticeable, and if she hadn't become so familiar with these surveillance videos that she was almost sick of seeing them, she might not have noticed it.

Xu Anran confirmed that the ticket was indeed there, and without hesitation, she got up and put on her protective suit, wrapping herself up tightly. Although she was anxious, she was still worried about contracting the virus, so she carefully checked her attire before going out to get the ticket.

It was rush hour, and the elevators were packed. Xu Anran took the stairs and ran all the way. People downstairs saw a white shadow flash by and stared at her in surprise. Some even thought she was crazy. Xu Anran didn't care about other people's opinions. She ran to the milk box, grabbed the ticket, and turned to run back.

Because I was wearing protective clothing, I couldn't directly touch the ticket, so I couldn't put it in the storage space. I held the ticket tightly the whole way, afraid of losing it.

Back in her apartment, she first disinfected herself from head to toe, then disinfected the train ticket several times. She hadn't had time to look at the ticket downstairs, but now she did. It showed the train was A174 from K69 to C621, with about six months to go. Xu Anran felt it was alright; going to the next world six months early was acceptable. She found a small box and put it away.

After taking off her protective suit, she put the train ticket into her spatial storage and disinfected herself again. Having obtained the ticket, she didn't plan to linger. Her luggage was already prepared; she packed her personal belongings into her spatial storage, changed into a new protective suit, and immediately headed downstairs to the underground parking lot.

She started the car, set the navigation, and headed towards the neighboring province. This city was going to be locked down soon, so she decided to go to another city instead. After driving for two hours, it was already dark. Xu Anran didn't want to drive at night, so she found a camping park to rest.

She felt that this viral infection was impossible to prevent. If she hadn't dreamt of knowing what the disaster was in advance, she might have unknowingly contracted the virus. Thinking of the enthusiastic Sister Lan, the boy who helped her, Xu Liang and the bespectacled man she had no connection with, and the many passengers struggling to survive, Xu Anran felt that perhaps she could remind them while ensuring her own safety.

So she turned on her computer and anonymously posted on the world's largest forum website:

The name is "Passengers Please Note".

Hello fellow passengers, both new and returning. I am also a passenger, and I have discovered important information during this journey.

This journey is dangerous because of the airborne virus.

Please take necessary precautions, pay attention to quarantine notices, and leave as soon as you find your ticket.

Heading to a city free of the virus, I hope we can all catch our next train smoothly. — A passenger from K69

Fearing the post would be blocked or deleted, the content was not explicitly stated, only vaguely mentioning the disaster, which passengers would understand upon seeing it. Xu Anran also bought an anonymous account online, set up a group chat, and had two accounts in it. She also wrote the group chat number in the post, and passengers who saw the post could join the group by answering questions.

The answer to the question is one that all passengers know: How many hours are left before they can enter the waiting hall? 24 hours.

Xu Anran called Sister Lan again, saying that she had found a post online and told her about its contents. She also mentioned that she had joined the group chat for that post. Sister Lan said she would take a look at the post's contents and thanked Xu Anran for reminding her.

After finishing all that, it was already past 10 p.m. Xu Anran's stomach was growling with hunger. She took out four Orleans chicken wings from the freezer to thaw, and then put them in the air fryer at 190 degrees Celsius for half an hour.

I took out another pack of cheese ramen and put it in the pot to cook. I also added some chicken balls, fish balls, crab sticks, beef rolls, and lettuce. After it was cooked, I took out the noodles and other ingredients, mixed them with the sauce, put two slices of cheese on top, and then fried an egg and a sausage and put them in the noodles.

By this time, the chicken wings were almost ready, so I took them out and put them on the table along with the dough. I also took a bottle of Coke from the refrigerator, turned on the car TV, and watched a variety show while eating, taking a bite of noodles, a bite of vegetables, and a sip of Coke.

The spicy chicken noodles were just right, paired with creamy cheese, juicy grilled sausage, crispy fried egg, tender meatballs and beef, and refreshing lettuce. Xu Anran was sweating profusely as she ate. Then, she took a sip of ice-cold cola, and the refreshing feeling made her relax completely, sweeping away the anxiety and busyness of the past few days.

Feeling stuffed, she sprawled on the sofa, finished watching the variety show, stretched, and washed and tidied up the dishes and kitchenware. She took out a change of clothes and went to the bathroom to shower. The bathroom wasn't large, but it was enough for her; turning around was a little inconvenient, but she was already quite satisfied.

After showering, I opened the bathroom window a crack to let it air dry. It's winter now, so I turned on the air conditioning in the car and the electric blanket on the bed beforehand. I unplugged it, got into bed, and fell asleep in no time.

While she was sleeping soundly, the group chat became lively, with passengers joining one after another throughout the night.
