This deep and dark passage seemed to have no end, and Guan Xiaofei and the others advanced in the passage for at least half an hour.

And they have been moving at high speed all this time, and according to the map they got from the bomb shelter, they have long reached the end.

As they went deeper, the bomb shelters became more and more old and decayed, and the smell of mold filled the air.

Guan Xiaofei, who was at the forefront, kept complaining, and they didn't know what kind of situation they were in now.

This is long beyond the scope of the map, and the only way to navigate is to a completely unknown territory, and the only way to navigate is by relying on the senses of the moonless.

"What's going on with this bomb shelter, isn't this a little too outrageous, how far has it been, hey, we shouldn't have gone out of the confines of Obsidian City, right?

Guan Xiaofei held a flashlight in his hand and looked ahead, the interior of the air-raid shelter was very large, which could accommodate several armored vehicles passing side by side.

"If you look at the function of the bomb shelter, this is indeed a bit beyond the normal scope, after all, the mission of the bomb shelter is to defend against the attack of a nuclear explosion, this depth and strength can do this, and with the scale of this bomb shelter, it can accommodate hundreds of thousands of people. ”

"It's especially confusing that this is beyond the population of Obsidian, and it's beyond common sense to build such a huge underground project and spend a lot of money to build an air-raid shelter that is not even needed."

Situ Weiyang dissected the bomb shelter, which was at least a few decades old, from another angle, and she was deeply skeptical.

"From the point of view of the function of the bomb shelter alone, this really does not make sense, unless ...... Unless ......"

Mu Qingshuang also smelled a trace of unusual smell, and she also began to look around, the existence of this air-raid shelter itself was very suspicious.

"Unless this bomb shelter was built to cover people's eyes and ears from the beginning, its real function is not to defend against the attack of a nuclear explosion, but to have another purpose, and this purpose is likely to be inseparable from the monster, the one you want to say is not to say this, right?"

Lu Zhen added the sentence that Mu Qingshuang didn't say, and the latter nodded, expressing his affirmation.

"Alas, it wasn't built to defend against a nuclear explosion in the first place, so why did you build such a big project? Is it a way to escape the heat and enjoy the coolness? Moreover, this air-raid shelter has a history of several decades, and in addition to the construction cycle, it will not be built in more than ten years. ”

"If you extrapolate from the node of time, the demon beasts have not appeared at that time, and they are still in a peaceful and stable state, since the demon beasts have not yet appeared, and they have not caused damage to this world, so why build a bomb shelter, doesn't this form a paradox?"

Guan Xiaofei was stunned, but soon he threw out his opinion, although what Mu Qingshuang and Lu Zhen said made sense, but time was a big problem.

"Time? From this point of view, it seems to be true, if it is an air-raid shelter built to deal with demon beasts, but there are no demon beasts in the age of construction, this point does not make sense, unless...... Unless...... No, no, how is this possible, I must have thought wrong. ”

Mu Qingshuang agreed with Guan Xiaofei's opinion on this point, but she soon seemed to realize something, and a bad guess formed in her mind.

However, she denied her guess in the shortest possible time, and quickly shook her head, if that was true, it would be too terrible.

Even if she was not stingy to use the greatest malice to speculate on the decisions made by certain groups, she still couldn't believe that they were true.

This is definitely just an unrealistic guess, Mu Qingshuang barely managed to squeeze out a smile, she comforted herself like this, trying to deceive herself.

"Well, I said what the hell are you talking to yourself there, it's very strange, what doesn't make sense, what can't be done, it's inexplicable. ”

Guan Xiaofei saw Mu Qingshuang's inexplicable look, and he didn't understand what strange things she thought of.

"What you want to say is that unless there is a linear connection between the construction of this bomb shelter and the monster, that is to say, it is a bomb shelter, or a building like this, which promotes the appearance of the monster and thus destroys the world? In fact, you don't have to deny yourself so quickly, this is very possible. ”

Lu Zhen once again said the words she couldn't say for Mu Qingshuang, although she was the youngest among these people.

But her excellent vision impressed both Situ Weiyang and Mu Qingshuang, this is definitely a very powerful character.

"Alas, Xiao Zhen, what are you talking about, I am getting more and more confused when you say this, what kind of straight connection, how can the bomb shelter be related to the demon beast again, it is getting more and more complicated, according to what you say, what place are we going to now, is it hell?"

Guan Xiaofei was even more confused when his sister said this, and this already very dangerous operation once again cast a shadow.

"So that's the case, if you think about it from this angle, although it's very unbelievable, but theoretically, there is still a great possibility, that is to say, the appearance of demon beasts is not an accidental event, and humans have been prepared before they appear. ”

"For example, more than ten years before the appearance of demon beasts, human beings began to consciously build things to defend against them...... No, although this speculation is somewhat probable, it is not the most likely one, and we can speculate from another angle, human beings have a certain purpose. ”

"They have built a lot of fortifications, including the bomb shelter under our feet under Obsidian City, and other kinds, but under the influence of humans, monsters have begun to appear, and if you think about it in this way, then all this can make sense. ”

Situ Weiyang integrated the logic of Mu Qingshuang and Lu Zhen and came to her opinion, which was affirmed by the latter two.

"What you said is really complicated, I still don't understand it at all, but it doesn't matter, as long as you keep going, no matter how complex the problem will be solved, thinking is important, but you have to go all out to do it, in order to solve the problem like peeling off the cocoon. ”

"That being said, I think we can slow down a little bit now, there seems to be some situation ahead, everyone should be careful, it always feels like something is going to happen, if something suddenly happens, if you are not careful, I can't take care of you. ”

Guan Xiaofei didn't spend too much effort thinking about what they said, he stopped and looked ahead vigilantly.

The darkness ahead is incomparable, like a giant beast with bared teeth in the darkness, and the next moment it will swallow them all!
