No matter how deep the darkness is, for Guan Xiaofei and his party, they have no way out, so they can only step forward.

The smell of decay began to waft through the air, which was unpleasant, and I had to cover my mouth and nose to keep my posture going.

Guan Xiaofei and the others, who had already had a premonition, walked forward cautiously, holding flashlights in their hands, which was an insignificant light that could be relied on.

A few minutes later, they began to hear the sound of "ticking" and "ticking" in their ears, which was the sound of water dripping down the wall.

"It's really quiet here, what we're trying to solve is obviously the problem of Obsidian City being invaded by the Demon Beast Legion, but I didn't expect to come underground unconsciously, and it always feels like I've come to another world, hmm?

Guan Xiaofei immediately became alert, and the flashlight in his hand flickered to the fact that there was a big black guy in front of him, and he immediately felt like a big enemy!

"Don't scare yourself, look at it clearly, it's an armored car, it's already covered with rust, and if you look at the style, this should be the old model more than forty years ago, it has long been eliminated, and look at the number, there are a lot of armored cars here, dozens of them. ”

Mu Qingshuang gave him a blank look, although she knew very well what could easily happen here, that feeling was too ominous, too bad.

But she was still sure that the bad feeling couldn't come from a scrapped armored car, which was a bit of a rumor.

"Ahem, of course I know it's just an armored car, it's not to be cautious, to see if you're on high alert, to see how you react, haha, but then again, how can there be so many armored vehicles here? And here's ...... Military kettle?"

Guan Xiaofei walked over, and with the help of the flashlight in his hand, he saw that it was indeed just an armored car, which made him breathe a sigh of relief and panic.

He groped around the armored vehicle, hoping to find some clues that would prove what had happened here, or there would be no clues.

They were simply confused and didn't know what was going on here, and that would happen in a weird bomb shelter.

However, after he fumbled around, he touched a round thing, which he only thought was a military kettle, and took it in his hand and looked at it carefully.

"Ahh

Mu Qingshuang, who has always been very bold, let out a scream after seeing the "military kettle" in Guan Xiaofei's hand clearly, and immediately scolded.

This made Guan Xiaofei inexplicable for a while, could a military kettle make her have such a big reaction? He was going to tease her for a while.

"What's so scary about a mere military kettle, really, this ...... That, big brother, I didn't mean to, I didn't mean to offend you, you just forgive me, rest well, don't come to me, don't sin if you don't know. ”

With the help of the light of the flashlight in his hand, Guan Xiaofei saw the true face of the "military kettle" in his hand, which was a skull!

Under the light of the flashlight, the skull was pale and the surrounding light was dim, which made Guan Xiaofei furious from the depths of his heart.

He hurriedly threw the skull out of the way, and anyone who could hold a skull in the dark of the middle of the night would be terrified.

The skull flipped a few times in the air before falling to the ground with a thud and shattering into pieces, though the skull had always been very hard.

But after decades of weathering, it has long become fragile, and the slightest external force is enough to make it shattered.

"Don't be surprised, this can scare people to death at night, these people...... How could they die here? And their clothes are relatively well preserved, and their posture is not a combat posture, as if they are sleeping with their backs to their backs. ”

Mu Qingshuang's degree of fright was no lower than Guan Xiaofei's, but she still adjusted in the shortest possible time, and she glared at him.

Quickly the light of the flashlight in his hand scanned the past, and it became clear that it was a defensive position, and behind the sandbags were a large number of soldiers in military uniforms, carrying military backpacks, and carrying automatic rifles, but they had been reduced to bones after decades of weathering.

Most of them were sitting on the ground, some of them had water bottles next to them, and their automatic rifles were placed next to them, as if they were fighting.

"These firearms have been obsolete for decades, but the environment here is relatively closed, the degree of corrosion is not too bad, they can still be used, and they are still in a state of insurance, which means that they are not ready for battle, and they died after a sudden attack?"

Situ Weiyang stepped forward to check, and she picked up an automatic rifle, which had not yet been loaded, which was particularly suspicious.

"Surprise attack? Is it like the ghost bats we encountered before? Otherwise, there are so many people, there are hundreds, and it is impossible for them all to die in an instant, this is really evil, what happened here, how could it come in such a hurry?"

Guan Xiaofei asked in surprise, after he settled down, he was not as frightened as he was just now, and began to carefully check the traces of the scene.

"No, if it was a ghost-headed bat, they would at least shoot back, but you see so many people, there is not even a single sign of counterattack, although there are traces of battle on the walls, but it can be judged that this is not a legacy of their fatal battle, it will take a little longer. ”

"What attacked them should come quietly, so that they were not the slightest bit unprepared, it was something that seemed harmless, no, maybe something invisible, like some kind of liquid, or gas or something, so that it could kill on such a large scale. ”

After Lu Zhen looked at it carefully, she came up with her argument, the mass death of so many soldiers here is a suspicion that cannot be bypassed no matter what.

"If there is such a thing, it does make sense, but what are so many of them here for?"

Mu Qingshuang still has a lot of doubts, everything must be purposeful, and what bothers them the most now is what these people want to do.

An attack on Obsidian City has now led to more and more things that are beyond their capabilities.

But even so, they will not have the slightest fear and retreat, and still maintain a posture of going all out.

"These rifles can still be used? No, Weiyang, if these rifles can still be used without rust, then what's going on with these armored vehicles, compared to the armored vehicles are too corroded, if the environment is the same, shouldn't this happen?"

Guan Xiaofei didn't participate in their discussion, but he quickly noticed something else that wasn't quite right, and asked.

"The degree of corrosion? This is really the case, the corrosion level of armored vehicles is obviously much higher than that of these rifles, even ten times, or even dozens of times the corrosion rate, what is the real reason for this situation...... Not good, all retreat, there's something in these armored vehicles!"

Lu Zhen heard her brother's words, and walked over to observe and compare, under the beam of the flashlight, Guan Xiaofei was holding an automatic rifle in his hand.

He took the rifle to the armored car for comparison, and the gap between the two was particularly obvious, which surprised Lu Zhen.

But she understood what the problem was almost instantly, and warned her loudly.

And at the same time, inside the armored car began to make a "clang", "clang" sound!
