Liu Haoyu remembered watching a film before, the subtitle of the film was "There is no absolutely safe system", and he felt that the plot design of the film was very good, and there were continuous reversals. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Combined with the results of Liu Yi's search, Liu Haoyu felt that to apply, there is no place in this world that cannot be found, as long as you are artificially created, there will always be clues, and it is only a matter of time before you are discovered.

After the first round of continuous searching, Liu Yi and the others did not find any experimental facilities. However, he was not discouraged, because according to Liu Haoyu's inference, this facility should be a very important and dangerous place, and it is impossible to build it on flat ground at will.

There was some element of luck in being able to find this hidden device, after all, the area of Demacia was too large, and it would take two or three years to find out what it would take to find out what it would take to find out all about it.

Luckily, as soon as I searched the third suspected area, I made a discovery. Following Liu Haoyu's warning, he entered the interior of the building without rashness.

"Did you survey with a scanner?" Liu Haoyu asked as he looked at the entrance of the cave that had already been covered with various vegetation.

"No, just this diagonal upward passage. It is expected that its main building will be less than 30 meters above the ground. Liu Yi shook his head and said.

If it is closer to the ground, it can be found in the first round of surveys. I also found this hole at the beginning, but because it was slanted downward, I thought it was a natural pit.

"Lao Peng, this biochemical suit can ensure everyone's safety, right?" Liu Haoyu asked Peng Boyuan again.

Both he and Peng Boyuan defined this place as the most dangerous level. There must be other viruses here, and what I am most afraid of is that these viruses will be mixed together to create a new type of virus with strong penetration. If that's the case, opening this place rashly will undoubtedly release a demon.

"Owner, you can rest assured, as long as this protective clothing is not damaged." Peng Boyuan nodded and said.

"Okay, I'll lead the team, let's go in and see what the situation is." Liu Haoyu nodded and said.

He really can't believe others, and since his strength has improved, he still has some feelings about danger sometimes.

The inner walls of the passage are covered with a variety of vines, as well as a variety of bryophytes that live only in humid conditions. Liu Haoyu scraped the moss off these passages, revealing the walls underneath. Only then did I figure out why the rest of the place was not detected when the detection began, and this channel actually had a shield.

"It seems that we really aren't the first humans to put down roots here." Liu Haoyu said with emotion.

At first, he could guess that someone had deliberately changed it, but that was just speculation. But all this that I see now is ironclad evidence.

After going down for more than ten meters, a spacious room appeared in front of me, and then the light on the protective suit showed that there was an elevator inside the room.

"It's finally the right place. Liu Yi, turn on the power of the elevator, let's go down and take a look. I don't know if Erha escaped from here, but we haven't seen any trace of human life until now. Liu Haoyu said after looking at it.

"There's definitely more than one exit to a building like this, and this one might be a way to get in and out. I don't know how big this underground building is, if it's too small, I'm sorry we spent so much effort. Liu Yi said with a smile.

"I don't think we will be disappointed, this one must have been built many years ago, and I guess it was at least a hundred years ago. At that time, they were able to build underground, and no matter what their purpose was, they would definitely not make a fuss. Liu Haoyu said with a frown.

He didn't know what the people behind it were trying to do here, but he knew that it was definitely not a trivial matter. And it should also be very secretive within their organization, otherwise the planet would not be left for others to discover.

After the external power supply was turned on, as soon as the elevator door opened, a trace of bitterness flashed in Liu Haoyu's eyes. On the walls of the elevator, the same sign that had once appeared on the Star of Hope, reappeared.

"Which floor should we go to see first, I'm afraid we won't be able to finish visiting here in a short time." Seeing the logo on the keyboard of the elevator until the thirty-third floor, Liu Haoyu said with a smile.

Needless to say, the scale at this bottom is definitely not small. Thirty-three floors, this is more than 100 meters of existence.

"If you want me to say let's go to the last floor, usually only the innermost thing will have the most important things." Liu Yi smiled and pressed the button on the thirty-third floor.

The elevator is a little shaky, probably because it has not been used for a long time and lacks lubricating oil. But the fact that it can still be used after being suspended for so long is enough to prove that the project here back then was also a conscientious project.

The elevator door opened, and by the light, there was nothing in an empty hallway, and there were many glass-door rooms on both sides of the hallway.

"Little San, can you connect to the system here?" Liu Haoyu asked Xiao San.

"Dad, there is no power here now, and there is no connection yet, only after the power supply here is restored." The mistress replied.

"Lao Peng, can you detect the presence of viruses here?" Liu Haoyu asked Peng Boyuan again.

"The passage is clean, I don't know if there is a virus culture room in those rooms." Peng Boyuan said after glancing at the instrument being tested.

Liu Haoyu put down his snack somewhat, it seems that this is not just a place to store viruses, there should be other uses. His biggest fear was that the virus would be released, and then Demacia would be in danger.

"Damn, isn't it, there's still one down there?" After inspecting all the rooms, Liu Haoyu said in surprise.

This area is supposed to be a rest area for people here, and there is no room like a laboratory as everyone used to think, but so far no humans have been found, not even corpses.

What makes Liu Haoyu depressed is that this is not the lowest floor of the building, and there is an elevator room in the innermost room. This elevator room is relatively large, 20 square meters, and I don't know what they use such a large elevator to operate.

"Liu Yi, let our people come down and conduct a comprehensive search on the 32nd floor above. Bring some more energy bars, and I guess going down is the key part here. Liu Haoyu said to Liu Yi again.

He also developed a strong interest in this place, and the construction of such a large project could not be completed overnight. Building underneath is much more complex than building on the ground, especially the further down you go, the greater the difficulty.

"Be careful, there's a virus reaction in the area ahead." Peng Boyuan, who had just opened the elevator door and had been staring at the instrument, reminded.

Liu Haoyu nodded, it seems that the area below is the key area of this building, and the upper area is only a living area built for people here.

Although the exploration has not yet been completed, a rough estimate suggests that if all the rooms above are full, there will be at least 500 people here.

What's even more terrifying is that the numbers listed on the keyboard in this elevator make Liu Haoyu's scalp tingle, and there are 26 floors here.

"What the hell is going on here, don't you want to make it so scary." Liu Haoyu said helplessly.

The situation here is really terrifying, Liu Haoyu is wondering if there is still this 26th floor, if there is any more, this organization is really terrifying.

This time he only descended one level, and he didn't rush to the rest of the levels. I casually found the wire, and after connecting the energy, let Xiao San check it along the line.

Luckily, according to Xiao San's show, the energy room of this underground building is on the 25th floor here. As long as you find the energy room, it's easy to do, and after restoring the energy here, Xiao San can find the main control computer here and take full control of this place.

"Damn,, this is a dungeon." After everything was done, looking at the entire architectural drawings shown by Xiao San, Liu Haoyu shouted in surprise.

The estimate of 500 is too conservative, and there are 2,569 staff members recorded here. And the buildings here are also quite complicated, as you can see from the structural drawing, it is like an ant's nest, and the rooms are densely packed.

"Lao Peng, you go to the area marked with virus research to have a look, mainly to test whether there is any virus residue. If there is, find a way to clear it directly. Liu Haoyu turned his head to Peng Boyuan and said.

Maybe this organization has its own purpose for studying viruses, but Liu Haoyu does not plan to continue researching this. This thing is too dangerous, such a big dungeon is quietly staying here, Liu Haoyu thinks it should be related to those viruses, otherwise how could Erha be inadvertently indifferent.

Peng Boyuan nodded, he had no interest in these viruses. While there are some gains to be gained from studying these viruses, it has to be managed. The situation here is still unknown, and everything has to be done carefully.

"Dad, everyone here is dead. And before they died, they also destroyed the main control computer, and no information was saved. Xiao San carefully read it for a while and then spoke.

"Can some of the dungeon's features still be used?" Liu Haoyu asked.

"Most of the functions have failed, and some of the wiring has been broken." Xiao San shook his little head.

Liu Haoyu sighed helplessly again, the area here is so large, there are so many rooms, only after Peng Boyuan is sure that there is no virus left here, he can send someone to check.

Anyway, he thinks that no matter what, this is his own territory, so he will clean up and study it slowly, and safety first. (To be continued.) )
