"It's finished."

As Bam's sure voice sounded, the huge alloy door that blocked everyone's eyes cracked an irregular gap from the center. Everyone heard a snorting sound of exhausting air from the inside out, and then with a rumbling sound, the two separate alloy doors slowly retracted towards the sides where they belonged, leaving only a passage that was tens of meters wide.

Through the light from the outside, you can see that the interior is full of mechanical punk architectural style, the cold and restrained brought by the metal makes people breathe, but more parts are hidden in the dark depths, like a veil, revealing an unwarranted mystery.

"It smells musty." Iowa said with a frown.

"It should be that the air purifier inside has stopped working, or it hasn't started at all, and it's normal for it to be in the ground for so many years." Bam handed over his things to his subordinates to pack up, clapped his hands and walked over to Yuan Yi and them.

"Good work." Yuan Yi symbolically politely nodded at Bam: "Let's go in." ”

Without waiting for Bam to speak, someone couldn't hold it back, and ran out at the speed of a 100-meter sprint, with a hahaha effect: "Go on an adventure, hahahahahaha, the big mackerel likes to explore the most." ”

“！” Yuan Yi's reaction was half a beat slower, just because there was only one way along the way just now, and there was nothing to make a fuss, so the big mackerel was quite safe, which made Yuan Yi relax his vigilance. Now looking at the double-ponytailed Lori who twisted her little butt and quickly disappeared into the shadows, Yuan Yi clearly recalled that this thing had always been a little expert in death. He hurriedly looked at the island wind on the side: "Island wind, quickly drag that stupid fish back for me immediately, don't let her run away." ”

"Hey, it's so dark inside, don't say it to the island wind."

"If you go, I'll play that doctor game with you next time."

"Hmm......" Daofeng was entangled for a moment, but it seemed that the doctor's shame role-playing game had an inexplicable attraction to her, she finally made up her mind and took the flashlight from Yuan Yi's hand: "The admiral promised me, but you are not allowed to make excuses to rely on the skin." ”

"Got it, find her and bring her back immediately, please."

The reason why she chose Island Wind is because she can quickly catch up with the big mackerel at her speed, and secondly, because among this group of people, only Island Wind is the most familiar with the behavior and habits of the big mackerel, although the island wind himself may never admit it, but in the eyes of the big mackerel, she has always regarded her as the best friend.

Since Daofeng agreed to Yuan Yi, he also quickly chased out in the direction where the big mackerel left.

Yuan Yi glanced around: "Then let's not be stunned here, let's leave quickly." ”

In response, everyone around him nodded in agreement.

Connecting the entrance is a semi-arc-shaped passageway, and once inside, you will find a large square.

Of course, it is not very accurate to use the term "square", its shape is somewhat similar to the ancient Roman arena, that is, the side is high, and the center is low, judging from the huge arch at the bottom, this should be some kind of assembly hall, but the space is not only extended downward, above the heads of the people, there is also a fairly wide space.

The huge iron bridges that span both ends create such a miraculous landscape, crisscrossing and stacking one after another, it is really amazing that someone can create such a small version of the town in such a small space that it is full of tension.

Originally, according to Yuan Yi's thinking, if there were 1,000 people to be accommodated in such a large space, it should be locked in a place similar to a bomb shelter, with a limited supply of food and water, and it would be almost enough to wait for rescue. But it turns out that people of this age could never have imagined the level of technology and production technology that human beings had at the height of their heyday—a scale that was limited by the size of the sanctuary itself.

Although the space is small, if it is distributed among 1,000 people, almost everyone in the area can have their own dwelling (surrounded by layers), there are also a number of complex rooms suitable for large populations, and self-consistent water supply and waste recycling pipes.

As a refuge, the conditions here are just too good.

The only fly in the ointment was that the supply of energy was interrupted, and Bam tried several times, but could not get it back up and running.

"I can't help it, probably because it's been too long." Bam used the lamp in his hand to shine on the tangled pipes in the distance: "It will take a lot of time to recover, but this kind of thing should not have too many technical problems, even if they have unique technology, they can replace it with our own familiarity." ”

"I'm honestly relieved." Looking at the empty hall, Yuan Yi suddenly said this.

"I'm honestly relieved too." Bam responded with the same tone.

The two looked at each other and smiled tacitly.

"Since there is no one here, then your inference is likely to be correct, if this place is not activated, it means that there is a large number of complete materials and technological items from the old human era preserved." In other words, we have developed this time, and Yuan Yi, who thought about it like this, couldn't help but be a little excited.

Bam nodded, although this was different from the clues he had been chasing through the rift to return to the past, but at this stage, it was also one of his goals to grasp the ruins as much as possible and trace the cause of the 'rift'. It's just that everything he does is based on the ultimate goal of being able to go back.

"Let's go explore another place."

Naturally, there is not only one such place in this space.

Leaving the researchers behind and letting them freely investigate the work nearby, Yuan Yi and Bam led the rest of the people through the main bridge and continued to move forward, and after passing through another arc-shaped passage, there was a different scene in front of them.

This is a very ordinary platform, the area is planned with white lines on the ground, and the ceiling overhead is closed by the hatch, and you can see its purpose at a glance - it is a helipad, but the whole platform is empty except for the high and low racks and cranes.

"Strange, why isn't there anything?" Xue Feng looked around strangely, but no matter how good her eyes were, it was impossible for something to come out of nothing.

"Could it be because they didn't start the sanctuary and didn't load these things...... Iowa said on the side, but she always had a bad premonition.

Yuan Yi, Bam and Beizhai on this side did not speak, and after a moment of silence, Yuan Yi said, "Go and see other places." ”

But as we walk down this path, we can see the extension of the survival support device (composed of a large number of pipes, gears, and shafts, similar to the movement structure that runs inside a clock, but in this case, the human living space is encased in these external components) and the storage room that was once supposed to be used as a repository, but everywhere it goes, what should have been stored there is missing, or rather, it never exists at all.

After going around, Yuan Yi and the others returned to the square where they first entered.

"How can this be ......"

"Looks like we're a little mistaken." Yuan Yi smiled bitterly, "It seems that the remains of this sanctuary are not unused, on the contrary, it has completely fulfilled the responsibility it has borne and sheltered the human race. ”

"But that woman just now...... Didn't the North House say that if there was really a rescue, the building could be separated? Iowa frowned: "And wasn't it sealed in the rock layer before we found it?" ”

"They probably didn't get rescued, but they survived quite a long time here." Bam's voice was also a little helpless.

The last sentence was answered by Yuan Yi: "In this confined environment, even if they have more advanced technology than us, but the supply of food and energy will definitely not be unlimited, they can't wait for rescue, and they don't want to wait for death in vain after the resources and food are exhausted, then there is actually only one way." ”

"What way?" Yukikaze still didn't understand.

However, Yuan Yi smiled, although the smile was quite bitter.

At this time, Iowa had already thought: "They will come out of this shelter in search of food, energy, and new settlements." ”

Don't......

She thought of a small, surprising, but impossible to ignore possibility, and Yi Ahua suddenly looked up at Yuan Yi, as if to confirm whether her inner thoughts were true.

Yuan Yi nodded: "It seems that this is the origin of our Asian union." ”
