Guan Xiaofei and his party finally went deep into the depths of the bomb shelter and found a large number of scrapped armored vehicles.

They were skeptical about why these soldiers were here, but they soon discovered something else fatal.

That is, the corrosion of armored vehicles is much more severe than that of automatic rifles on the ground, and when they realize that something is wrong and start to warn.

The sound of "clang" had already begun to be heard in these armored vehicles, and after a while, black smoke even came out of the heavy armor of the armored vehicles.

A mist of gas spilled out of it, and it wasn't just one armored vehicle that reacted, it was all here!

Hundreds of black mist gases floated towards Guan Xiaofei and his party like conscious beings, filling them lightly.

This made Guan Xiaofei feel inexplicable for a while, and he was still stunned and didn't come back to his senses for a while, until someone dragged his clothes and ran wildly.

"You idiot, what are you doing here, waiting to be swallowed up by this black smoke? Get out of here, it's too dangerous!"

Mu Qingshuang scolded him, the light of the flashlight illuminated the road ahead, looming, and their hurried footsteps were unusually harsh.

And the "snort" sound from the black smoke corrosion came to his ears crisply, which made people can't help but feel creepy, and the coolness penetrated through the heart.

"Black smoke? What is it? Is it that black thing? I'll go, what's going on, the good armored car has decomposed like jelly, how corrosive is this, aqua regia is not so powerful, it's a little bit of it?"

Guan Xiaofei raised the flashlight and subconsciously glanced back, and the armored car, which was already very corroded, was seriously deformed.

All of them were paralyzed like mud, and a steady stream of misty black smoke came out of the armored car, and the light was faint.

In the limited light, you can clearly see that the shape of these black smoke is strange, and it has been unpredictable and has no specific shape.

"I think they're the ones who made this place like this, let's get out of here quickly, and if we continue to grind here, they'll be corroded to the bones, oh no, there's no road here, it's blocked? It's not good to go on like this. ”

Mu Qingshuang walked at the forefront to lead the way, and when she suddenly encountered such an accident in the dark environment, few people could still maintain their composure.

Just as they moved quickly and tried to escape from this dangerous area, they soon found that the road ahead was completely blocked.

"This should be that these soldiers discovered the existence of these black smoke, so they built such fortifications to resist their invasion, but they were all blocked, and we couldn't pass through it at all, if this continues, the black smoke will soon fill over, and then it will be dead!"

Situ Weiyang walked in front of this completely sealed wall to investigate, and what happened to them was not good news for them.

"Hey, since it's smoke, then we can blow it away, it's light, as long as there is a gust of wind, it won't be a problem. ”

Guan Xiaofei saw the black smoke changing its appearance approaching them, and he swallowed his saliva and proposed a solution.

"If only a small puff of black smoke could dispel them, but there is so much black smoke here that it is almost enough to completely fill this large section of the bomb shelter, and there is no wind in the bomb shelter at all, but they still float over, which shows that they are not driven by the wind but conscious. ”

Lu Zhen shook her head and rejected her brother's proposal, the black smoke was getting closer and closer to them, leaving them with less than ten seconds left.

"Then we can only sit here and wait for death? Before we have completed our mission, we will fall here first, damn it, it is really unwilling. ”

Mu Qingshuang gritted her teeth, she clenched her fists, her palms were full of cold sweat, in the face of this terrible threat of black smoke, they had nothing to do at all.

"Wait a minute, since these black smoke are blocked on the other side of the passage, how did they invade? There must be a passageway, we must calm down, we must find that passageway, only then will we be saved, otherwise it will really be finished." ”

Situ Weiyang calmed down, she started from the crux of the problem, immediately reminded Guan Xiaofei and others, and began to look for the location of the passage.

"That's right, there must be a passage before these black smoke can enter here, otherwise this fortification they have piled up is meaningless at all, hurry up and look for it, find it, it's really imminent now...... There you have, look, there, there's a passage there!"

Mu Qingshuang agreed with Situ Weiyang's words, and immediately began to look for the location of the vent, and soon succeeded in finding it in the upper right corner.

"Alas, the passage mouth, this is only the size of a palm, how can it be passed? Even if you use a drill, you can't do it, I don't think you are overestimating us, this is not a suitable position for a breakthrough, miserable, miserable, miserable, it's going to end here." ”

Guan Xiaofei originally had a little hope, but soon saw that the size of the passage was simply not enough to accommodate them to pass through.

This began to become discouraged again, the black smoke was only ten meters away from them, and it took less than two breaths to completely annihilate them!

"This must have an opening enough for us to break through, you are really stupid, if you don't want to finish, then act immediately, be fast!"

Mu Qingshuang didn't have the leisure to grind with Guan Xiaofei, she exchanged glances with Situ Weiyang, Lu Zhen and the others and stepped on the wall.

Situ Weiyang, on the other hand, turned around and used her ice attribute card to open an ice wall to delay the momentum of the black smoke invasion.

If they didn't do something to stop it, they wouldn't have had enough time to get out of here, but even then.

The open wall of ice also made a constant "click" sound, and soon it was covered with cracks, apparently suffering from the invasion of black smoke.

Vapor continued to come out, and the ice melted into a corrosive liquid under the influence of black smoke, accelerating the collapse of the ice wall.

At the same time, Mu Qingshuang had already moved to a height of seven or eight meters in the air, appearing at the mouth of the passage, and she summoned the Red Phoenix Sword.

Stabbed towards the passageway, this is the only way to widen the passage and let them escape, or everyone will be doomed!

"Hey, you'd better hurry up, if you don't get it done, the black smoke will come, and then we will be miserable, can you do it?"

Guan Xiaofei anxiously urged, seeing these changing forms, sometimes like fierce beasts, sometimes like black smoke of evil ghosts.

He's hairy from the heart, especially since they also have a creepy, hoarse voice, like grinding their teeth.

This made the pores of his whole body can't help but open, and with the cold brought by the ice wall, the chill penetrates into the bones, and he can't help but shiver for a while.

"Don't be verbose there, instead of grinding and chirping, it's better to do something practical, don't come here to make trouble, if you say this passage, it will be broken immediately, and the red lotus will burst into flames!"

Mu Qingshuang knew the importance of time, and everyone's safety could be said to be tied to her body, and she clenched the long sword in her hand.

Under the effect of the firelight, the surrounding scene was illuminated thoroughly, and the light that bloomed at that moment was accompanied by a rumbling sound.

The sealed stone finally shattered around the vent, and a gust of wind swept up.

Under the effect of this heat wave, the ice wall was completely shattered, and the black smoke floated smoothly.

Even though there is heat to resist, it is too small for the black smoke.

Seeing that Guan Xiaofei and the others were about to be completely devoured by them.

"Success! Hurry up, we'll get out of here now!"

Mu Qingshuang saw the crumbling stones, which were large enough for one person to pass through, appeared, and she dragged Situ Weiyang and the others and pulled them over one by one.

It seems that he managed to dodge the catastrophe.

"Hey, don't forget me, and me!"

Seeing that a few of them turned over smoothly, Guan Xiaofei, who was still at the bottom of the line, opened his throat and shouted.

The black smoke was only three or four meters away from him, and it was about to bite his ass soon!

"It's all said don't be shocked there, hurry up and come here, let's get out of here!"

Mu Qingshuang finally reluctantly reached over and grabbed Guan Xiaofei, and pulled him over before his butt was bitten.

The black smoke was intercepted by this wall, and the entrance to the cave through which Guan Xiaofei and the others passed was once again sealed by Situ Weiyang by the ice wall.

This bought them a few more seconds to wait for the black smoke to break through the ice wall and come to the other side.

Guan Xiaofei and the others had already fled and had no trace.
