Looking at the flames on the bonfire, Su Mengfan thought of the previous question about knowledge for a while.

I thought of the tens of thousands of books I had seen in the library, whose worth before the war could not be measured in monetary terms.

Nowadays, only the Polis Metropolitan is the only one in the subway who sends people to look for books on the ground.

What matters is not the book itself, but the knowledge on it.

But in this environment, those books are far less important, and perhaps only survival is real knowledge.

"But what exactly is knowledge?" He asked himself over and over again, wanting to add a little value to what he had just cowardly pushed away.

He was so engrossed in the question that he didn't notice how many times he said the words out loud.

"My friend, knowledge is light—and the absence of knowledge is darkness!" An officer on duty eagerly explained to him.

"Right?" He asked, glancing happily at his friends.

Su Mengfan was stunned, he stared at the officer on duty, and sat like this in a daze.

Until Bourbon came back and pulled him up, saying that he had just been detained and that now they had urgent matters to go, and then he said goodbye to the officers on duty.

"Be careful!" The commander warned him menacingly, "I'll let you leave here with your weapons." ”

He waved one hand at Su Mengfan's machine gun and said, "But you can't come back with it." I have given a clear order on this. ”

"I'm telling you, you're a pig's brain......" After they hurriedly left the fire, Bourbon angrily yelled at Su Mengfan.

"On the way back, you can do whatever you like. However, you will be beaten. I don't care about this. I knew, I knew this was going to happen, you bastard. ”

Su Mengfan didn't say a word, and almost didn't listen to a word of Bourbon's babbling scolding.

Instead, he suddenly remembered that he had been on his way to {Peace Avenue Station}.

At that time, I tried to listen to it, but I couldn't grasp the melody of the tunnel at that time.

But remembering the feeling when he sat by the fire a few minutes ago, Su Mengfan felt that he had just heard such a melody.

He's listening, really listening—heard!

It's the melody of the tunnel.

However, the scene that had just happened quickly faded in memory.

Half an hour later, Su Mengfan was no longer sure if these things had really happened, not sure if he had imagined it, not sure if it was a burning fire blowing out the air wandering around.

"Well, you probably didn't mean to, you just got a water in your head." Bourbon reassured.

"I apologize if I don't look so good to you. It's a stressful job.

But, well, it looks like we're out of danger. Now, we have to rush non-stop to {Qingtang Station}. Once there, we can relax.

If everything is in order, it won't take us too long to get there. But after that, things are not easy to say. ”

"Okay, let's just keep going like this, okay?

I mean, if we're on a tour from {Ciudad Gomes Station}, if there's less than 3 people in the group, then we're going to stay.

Because no matter what, you need a defender......" Su Mengfan said, glancing behind him.

"Well, there are certainly a lot of benefits to participating in a guarded, all-encompassing tour." Bourbon began to explain.

But listen, the downside is obvious. I'm used to worrying too much.

Forget teams of three, we're used to having at least five people everywhere.

Did you find this helpful? It's not useful at all.

At one point, we sat in the van, so there was protection: two people in front, three in the middle, and one in the back – everything was already arranged.

We are going from {Tretyakov station}...... Where...... It used to be called {Bisilletu Station}.

There are no problems with the tunnel.

But there was something in the tunnel that I didn't like at all, a certain rotten smell.

Moreover, there is also fog.

Hell, we can't see five steps away – and the flashlight doesn't do much.

But we decided to tie a rope to the belt of the broken man, then through the belt of one of the people walking in the middle, and finally to connect the commander who was in the lead.

That way, no one will get lost in the fog.

We walked forward with ease, everything was normal, it was going well, there was no need to rush forward, we hadn't met anyone yet.

It was about 40 minutes like that, although in the end we picked up the pace. He began to slurred his words and was silent for a few moments.

One of the three in the middle, Toyan, went to ask the man behind the mat something, but the person who was asked did not answer. Toyan waited for a while and asked again.

Silence.

Toyan dragged the rope, and he pulled it to the end.

Something was neatly bitten off there, it was real—the whole thing was bitten off, and there was even something sticky left on the end of the rope...... The man behind the mat disappeared without a trace.

They didn't hear anything, they didn't hear anything.

I walked with Toyan. He showed me the end of the rope and my knees were shaking.

We turned around and shouted the name of the man who had been broken, but we couldn't hear any response.

No one responded to our roars.

We exchanged glances - and kept going, wishing we were already at {Bisilletu Station} in the next second. ”

"Maybe that guy is joking?" Su Mengfan still has hope.

"Are you kidding? Maybe.

But he never showed up again.

From this incident, I have learned some truths: what is destined is what is destined, you can't change it, and it's useless to be vigilant. You haven't been to many places.

I've been to all places with people in pairs, and if you like it, just find a partner.

Except for one tunnel – from {Turgenev station} to {Sukharev station} {Turgenev station} - this is a special case.

If there's something going to grab you, then you're going to be dragged away in the blink of an eye, understand? ”

"Understood. So, they're going to let us into {Qingtang Station}? I'm at least still carrying this thing......" Su Mengfan said, pointing at his machine gun.

"They will let us through security. But when you get to Metro Circle Line 5 - of course it's not that easy, they won't allow you to enter in any way, and you have no hope of getting in with this weapon.

But we don't need to go in. Anyway, we don't need to hang out there for too long, we just do a short stop and move on.

You...... Have you been to {Cheongtang Station} before? ”

"Haven't been." Su Mengfan didn't have any impression of this subway station, only saw it on the map.

"Okay, why didn't I wake you up sooner?

Anyway, there weren't any guardrails there - they didn't need this thing at all.

There's a market there, and no one lives there, so there's no problem.

But the soldiers of the Red Line will patrol there and maintain order there.

So, you have to behave in a proper way, you know?

Otherwise they will send you to hell and they will deny you access to any of their subway stations.

When we get there, you just climb up to the platform and sit quietly. He gestured to Su Mengfan's machine gun.

"Don't take it and wave it around. I'm going to find something first, and I'm going to bring someone here.

So, you have to sit and wait.

Then, we'll set off for {Qingtang Station}, and we'll talk about how to get through that damn corridor to {Turgenev Station}. ”

Bourbon fell silent again, and Su Mengfan stayed alone.

The tunnels here aren't too bad, the ground is a little damp, and the rails are bursting with black, thin streams of water, as if they're all flowing in the same direction.

After a while, there was a sudden squeaking sound, mixed with a rustling sound, which to Su Mengfan's ears, was like a fingernail rubbing against glass.

He stepped back in disgust—the little beasts hadn't yet appeared, but their presence was already felt.

"Mouse! Exercise! Su Mengfan spit out a dirty word, and felt goosebumps all over his body.

He still saw them when he had nightmares, though memories of that horrible dark hour were almost gone.

At that time, his mother and the entire subway station were buried at the hands of a swarm of rats.

Is that memory really gone?

No, it just hides deeper, like a needle that remains inside, deeply rooted in the body.

It is propelled by a doctor with poor technique, traveling around the body.

At first, it was hidden and sat still, but after a while, an unknown force moved it again.

Passing through arteries and nerve endings in a lethal way, destroying vital organs, it is destined to cause unbearable suffering.

I remember the thunderous power of those beasts at that time, and the insatiable greed and cruelty they showed.

The memory of the terrifying experience was like a steel needle deep in the subconscious, and it slipped out at night to harass Su Mengfan.

The mere sight of them, or even the faint smell of them, caused an electric current in his body, causing his body to reflexively tremble.

There is hardly a single rat at the Hayabusa station: there are rattraps everywhere, and poison is scattered everywhere.

Therefore, Su Mengfan put his mind at ease.

But rats crowded the rest of the subway, and he had forgotten about that.

Or maybe they avoided the question when making the decision to embark on this trip.
