It's been half an hour since I ran, and everyone is out of breath and sweating profusely.

The dim light ahead illuminates the way forward, but the road ahead seems to have no end, entering one room and soon reaching another. Even now, everyone has touched the entire floor.

These rooms are either warehouses or workshops, and even the rest area has not been found, and it is simply a production base. But since it is a production base, there must be a channel to the outside world, or to other places, otherwise how to transport the things made?

The problem is that everyone has not found this transportation channel until now, and the poisonous gas behind them has forced everyone to keep running forward. At this level, at least a large part of the area will definitely be covered by those poisonous gases in the end, and I don't know if the position I am in now is safe, so I can only find this transportation channel and see if I can go down to the next layer, so that I can have a greater chance of escaping this catastrophe temporarily.

"Let's slow down a little."

Branster said, and slowly stopped, and began to walk forward.

The speed was much slower than before, but everyone was able to catch their breath.

The spread of poisonous gas behind them will not be divided into different directions, and it will float upward, which means that when they pass through those rooms, they will stay here for a while, after all, it will fill the entire room, and then spread out from those doors, it will also take a while, and the spread of these poisonous gases will definitely not move as fast as they are, after all, they have been running for a long time before. The time difference between these openings is enough for me to breathe for a while.

However, it is not a matter of going on like this, it can only treat the symptoms but not the root cause, and it is best to find a completely safe place.

At this time, Zhang Tianhai walked to Brenster's side and whispered, "Have you found a problem?" ”

"What?" Branster asked.

Zhang Tianhai touched his chin and said: "Those poisonous gases can basically be determined to be the culprits who can turn people into zombies, so that means that there were originally zombies here." They must have been poisoned by these gass. So many zombies. It is almost certain that the poison gas spread to the entire base at that time. But here's the problem. ”

Branster also understood what Zhang Tianhai meant: "You mean, these poisonous gases...... Is it volatile? ”

That's pretty much what it means. If the gas hadn't volatilized, we'd be dead by the time we walked in. ”

That is to say. We have a chance to go back. Branster's eyes lit up. But then he frowned again: "But this place has been abandoned for I don't know how many decades." Such a long time is enough for these poisonous gases to deteriorate, but it doesn't mean anything, right? ”

"At least we can try. These gases are colored. Even if they don't volatilize for a short time, we can scout it. It's already very deep underground, and I don't think there will be any decent exit. When we really have no way out, we can try this method. ”

Branster thought for a moment: "Kind of makes sense...... Let's just write it down and think of it as the last path when there is nothing else to do. ”

Zhang Tianhai nodded: "At least you shouldn't try it now, these poisonous gases are floating upward, if the situation is bad, the upper layer may have been invaded by poisonous gases now, and it is impossible to go up safely no matter which way." ”

"Everybody come here!"

Suddenly, in the middle of the line, a voice appeared. All of them stopped and looked over.

The one who reminds loudly is a twin angel. She pointed to a fork in the road that everyone was about to pass through and said, "Come over here, shall you?" ”

"What's wrong?" Branster asked, as he walked over.

The twin angels pointed to the road and said, "Here, there's wind. ”

"Wind?" Branster was startled and looked this way.

Sure enough, after feeling it carefully, Branster also felt a gust of wind blowing towards him. The wind is very light, and if you don't feel it carefully, you really don't feel it.

It stands to reason that there could be no wind in this place, and this is an underground base that has been buried underground for many years. But it can also be thought that the ventilation facilities in this place must be very good, otherwise when you go down to this place, you will already be able to feel poor breathing or even suffocation.

And now, at least everyone is still breathing without any discomfort, which proves that the ventilation facilities in this place are still in good condition and there are no problems. Thinking about it this way, this wind should be the wind blowing in from the nearby ventilation facilities.

Branster's eyes lit up.

Ventilation facilities...... This thing must be leading to the outside world!

If the space inside it is large enough, then it is completely possible to leave this base from this place. Even if it can't get in, and there is no way to leave here, the connections of these ventilation facilities must be in some important locations.

Maybe you'll find something.

Thinking of this, Branster ran directly in that direction, and a group of people behind him immediately followed Branster when they saw it.

Turning into this corridor, there were no other forks in the road, but many steel gates appeared in front of everyone's eyes, but it seemed that their control system had been completely destroyed and could not be completely closed, leaving a gap about a meter wide for people to pass through. And when they saw this steel gate with a thickness of about half a meter, everyone began to feel a little surprised in their hearts.

Such a heavy gate, when working normally, the defense is very high, and if it is controlled by high strength, its defense can even block the attack of missiles. Such a gate will naturally not be used anywhere casually, and it can be guessed from here that behind the gate, it may be a more important area of the base, even if it is not the core control area, it is very likely that you can find something you want here.

However, when everyone passed through the gate of Guò, they still did not let down their vigilance. There are zombies here, if you rashly enter an unfamiliar area and are ambushed by zombies, then the death is simply too miserable. And I don't know if anyone has set traps or set ambushes in these places, so it's always good to be careful.

As soon as you enter the gate, the lights in the area behind you begin to dim and dim until finally, it becomes dark.

It's like the same state before the power supply to the base was turned on.

All of them turned on their flashlights, shone the road ahead, and continued to move forward step by step.

The hallway wasn't very long, and after two or three minutes, a hidden door appeared in front of it. When I arrived at this place, the wind blowing from behind the door was more clearly discerning. Branster looked behind him, then held on to the door and slowly pushed it open.

The place where the gate was connected was already rusty, and when I pushed it open, a harsh and ugly sound suddenly came to everyone's ears. But in the next moment, an echo of the door also appeared in everyone's ears.

There is an echo, which proves that the space behind it is actually very large.

Branster raised his gun and walked out slowly.

The place is indeed big, very big. It was surrounded by huge brackets made of steel, one horizontal and one vertical, cutting the entire space into square shapes. You can see the hallways that are several floors higher than you, and there are some ladders that you can climb up to. In the center of this place, there was a huge platform, and in the middle there was something made of metal, similar to a tray, but they had long since lost to time, and it was completely impossible to see what they looked like when they were in good condition.

In the vicinity, there are also a lot of trailers, forklifts and other tools, directly ahead, there is also a place that is obviously a control platform, but it is still far from here, and the protection seems to be particularly tight.

And these are not the most important things. The moment you come in, there is only one thing you notice, and that is the top of your head.

Compared to the area and width of this space, the height of this place is very, very high, even several times larger than the width of the entire space, you can imagine how deep it is. At the highest point, a rectangular light spilled down from above, shining directly on the ground, illuminating all the surroundings. The light is very strong, but it is not dazzling, on the contrary, it makes everyone feel a little comfortable, some impurities and dust floating in the air, in this light, can be seen clearly, and even some particles that do not understand what they are, are still slightly shiny in it.

Underneath the light, there is also a large area of earth. It's not the dust that the base is all about, it's patches of dirt. The earth had accumulated a lot, and it looked like it was about three or four meters high, and it was piled up there to form a small hill, which must have been formed by falling from above and slowly accumulating here.

It is this light that fills the surroundings with a dilapidated atmosphere, which not only does not add some color to the place, but makes people feel that it is lifeless.

Everyone looked at it, and all of them were surprised.

That's right, this kind of light is all too familiar to everyone. Isn't it the light of the sun?

Directly above this place, it is connected to the ground! And those winds are coming from the top of their heads.

Everyone feels that they have not seen the sun for a long time, and even now that they know that it is impossible to climb to such a high place, their mood has become relaxed the moment they see the sun. Everyone stood under the sun, feeling the blinding light above, as if they had found some treasure. (To be continued......)
