Yibo is standing at the window on the top floor in the hospital, looking out at the city. Or what once was a city and now does not remind of it. Destroyed buildings, still burning buildings and all the corpses, here in the hospital and also on the streets.

And although it's almost 10 am, it still hasn't really gotten daylight. "Eerie this sight. It kind of reminds me of the Van Helsing series when I look at the sky and the burning city."

"Uh-huh, and now you think hundreds of vampires came crawling out of their holes and just destroyed everything?"

"I didn't say that."

"Maybe you'd better not say anything then, until we find out what happened here."

"Yes officer."

"Don't give me that shit okay?"

"What?"

"That sarcastic crap. It really doesn't need to be in a situation like this."

"But it's the only way for me to deal with this right now. Because honestly Officer Wang, there's my dead chief doctor over there, looking like a wild animal attacked him. My colleagues are dead. Patients and visitors are dead. And I have no fucking idea what happened. All I heard was their screams and desperate banging on the door."

"Do you think my colleagues are better off? The two colleagues at the front desk are still sitting burned at the reception desk waiting for people to come for help. My boss is burned as well. And even worse, none of them seemed to have put up a fight! But I'm not being sarcastic or freaking out about it either."

"I'm not freaking out, all right?"

"Yeah good. We should stay here for a few more days and see if any other survivors might come here."

"So you're welcome to stay here and wait. I'm going to go to the hospital parking garage right now, to my car and then get out of town as fast as I can."

"I don't think that's a good idea doctor."

"Oh no? You just wait and see. Pretty soon the air will be barely bearable because of all the smoke and ash. Besides, the bodies are slowly starting to decompose, which means their stench will soon become unbearable. On top of that, we have no idea what happened. And I don't intend to wait here until the thing that killed all these people comes back. I'm offering you the chance to come with me. Because it's better to survive in pairs. But if you don't want to, just stay here and I'll go alone."

"Say, can't you just be quiet for five minutes? Ever since I woke up, all you've been doing is talking and talking. My head is really starting to burst. You get on my nerves so much with your babbling. I'm really grateful that you helped me and took care of my laceration. But really just shut the fuck up and let me process all of this for a second."

"Oh wow. You know what? If I'm annoying you like this, you stay up here and I'll go downstairs, pack up my stuff and get out of here. Happy survival to you officer Wang."

"Hey no wait, I didn't mean it like that." Yibo shouted after the doctor. But the doctor kept walking and left the station. "Damn, I'm sorry okay?" He shouted again louder. But doctor Xiao didn't come back.

Yibo was annoyed with himself for being so harsh to the doctor who probably saved his life. And he hadn't meant to say such mean things, either. But at just 23 years old, Yibo feels totally overwhelmed by it all and doesn't know where his head is at the moment.

To apologize to the doctor and make sure that he doesn't leave without him, Yibo wanted to run after him. But just as he was about to head out the door, he noticed a huge shadow fly past the window. He rushed back to the window, but couldn't see anything.

He ran as fast as he could out of the patient room and to the stairwell. Hastily, he ran down the stairs to find Doctor Xiao. He came back to the station and saw the doctor standing frozen at the door. He ran to him and touched the doctor's shoulder. The latter was so frightened that he cried out briefly.

"What's wrong?" Yibo wanted to know.

"There was this thing. This huge black thing with wings and it grabbed two of the bodies and flew away." Replied Zhan.

"What, that's crazy. You imagined that." Said Yibo in response. But then he remembered the giant shadow again.

"You don't have to believe me. But trust me when I tell you we should get out of town as soon as possible. Whatever that creature was, it's hungry and it'll be back. And I don't think there's just one creature."

"What makes you think that?"

"Look up there." Replied Zhan. He pointed his finger to the sky, where Yibo saw quite a few black flying creatures. 

"Oh my god. What are these creatures?"

"I have no idea. But I doubt it's a good idea to try to leave town during the day. However, we can't stay here either. Too many windows."

"So what are we supposed to do now? If we can't get out, where are we going to go?"

"Back to the basement."

"To the bodies where you were locked up? No way!"

"No, not to the bodies. There's an old tunnel down there. I don't know what condition it's in. But it could be our salvation. It was built back then, in case there was an air raid and escape was only possible underground."

"If this tunnel exists, why hasn't anyone taken it? I mean from those who tried to get into the morgue to hide there."

"Well, many don't know about the tunnel. And I only know because my grandfather was already a doctor here and showed me the tunnel back then. But there's another problem, apart from that I don't know what condition the tunnel is in."

"What problem?"

"The tunnel is blocked by a huge door that we need a key for or something to pick the lock with."

"I learned something like that at the police academy. However, we shouldn't go down there unprepared. We'll need flashlights and batteries."

"I had thought of that before. I emptied a first aid kit and then filled it with essential medications, water bottles and snacks. I also found four flashlights and batteries. I just wish I could remember where this tunnel actually leads?"

"Maybe to a bunker? It used to be that way most of the time."

"I don't know. Either way, we should make sure we get down there. Before those creatures in the sky decide to come by the hospital for a visit."

Yibo agreed with the doctor. They got the suitcase and the flashlights and then went downstairs to the basement. They had to go through several different hallways and doors before they stopped at a massive door and Zhan told him that this was the door in mention.

Yibo took his lock picking tool out of his breast pocket and immediately got to work. Although he was learning it at the time, unfortunately he wasn't very good at it of all things. He hoped that with a little help from luck, he could somehow get the lock open. And because they were here in the basement and far away from the staircase, the pressure in Yibo increased even more. Because that way, they also couldn't hear if these creatures came into the hospital.

After a few minutes, Zhan got fed up and asked Yibo to let him try. Because he wanted to get out of here before these creatures found them here. He didn't really know what he was doing and just tried his luck when suddenly the lock clicked and the door opened a crack. "Wow, panic is sometimes helpful." He said, grinning at the officer.

"I'll go first." Said Yibo.

Zhan shook his head and replied, "We'll go together, okay? I'm sure as hell not going to run after you and get my butt bit."

Yibo shook his head and said, "Then go ahead and just be quiet for a few minutes before they hear us after all."

Zhan pretended to zipper his mouth shut, put a lock on it, and throw away the key. "Childish." Said Yibo in response, taking the suitcase because he didn't think he doctor could carry it for long with his skinny arms.

The unequal pair entered the tunnel, cold air flowed towards them. Zhan closed the door and slid a latch in front of the door that was there. "Oh yes the tiny latch will surely help." Said Yibo in response.

"Oh sure, what was that about sarcasm? I can't but you can Officer Wang?"

"Shut up, come on now."

"Hey, don't talk to me like that. I'm older than you, so you should have respect for me too."

"Boring."

"What's boring."

"You're boring. Extremely boring, in fact. Now get moving or do you want to grow roots here?"

"God what an asshole." Murmured Zhan.

"I heard that!" Replied Yibo.

Zhan shrugged his shoulders and walked past Yibo. "Hey White Coat, didn't you say we were going together?" Asked Yibo as Zhan walked a few feet in front of him.

"My name is Xiao Zhan, feel free to call me Zhan. My name is neither hey nor white coat, remember that. And you just said the latch is useless. So we'd better hurry. I don't want to stay in this tunnel any longer than necessary either honored officer Wang."

"Yibo, I, my name is Yibo. How old are you actually Zhan? And yes you are right. We should hurry up."

"I'm 29 years old and now come on. I want to get out of here and see daylight again as soon as possible."

The two walked together down the tunnel, which seemed to them to be endless, and then stopped. There were three turnoffs in front of them, and of course none of the turnoffs had any indication of where they were going.

"What now? Do we flip a coin?" Asked Zhan.

"Only if you have a coin with three sides." Replied Yibo, taking a closer look at the three passages. However, he could not see anything. "What do you guess, how many degrees do you think it is outside right now?" He asked Zhan.

"Mhhh, I would say around 25°C, why?"

"Because there's no warmer air coming out of any of the three tunnels. It's cold as fuck."

"Is there any real draft then?"

"No, not really. The air in the Middle Corridor is colder, though."

"So what now? Do we take the golden midway?"

"Yes. If we don't get anywhere, we can go back and try one of the other two."

"Okay, let's go." Replied Zhan.

The two entered the middle passage and kept walking through it until Zhan saw a ladder leading up. To a sewage cover. But since it was still daytime and the creatures would surely see them immediately if they climbed out of the ground somewhere, they decided not to take that path for now and keep walking.

However, the path ended in a dead end. All they found at the end was a small pool of water in which old sewage had collected, which stank terribly.

They walked back the way they came and looked at the left passage, but there wasn't even a ladder, it just ended with another pool of sewage, just like the right passage. They now have no choice but to wait until the sun has set and then try through the sewage cover.

Zhan, meanwhile, checked the wound on Yibo's head again and carefully feels it. Which Yibo returned with a curse. Then Zhan gave him an antibiotic and a painkiller. After that, there was nothing left for them to do but sit there and wait. And because Officer Wang Yibo prefers silence, they didn't speak a word to each other. Which was especially hard for Zhan.
