Chapter 2622

Although the door is also shrouded by the magic energy array, its simple and thin structure makes it difficult to describe the advanced techniques in the magic energy array, such as three-dimensional magic patterns, overlapping magic patterns and so on. Therefore, although there is an extension of the magic energy array on the door, it belongs to a relatively vulnerable part of the whole magic energy array.

Just look at these two buildings.

All the doors of the two buildings were damaged. Even if there is a magic energy array attached to the door, the door should be broken or broken after being impacted by a large number of witches and ghosts.

Therefore, when angel saw a still intact door, he was actually quite surprised.

Why is the door here still intact?

With doubts, Ingres came to the door and quickly built the "server" of Narda's eye in the thinking space. By running the knowledge accumulated in the "server", Ingres quickly identified all kinds of information of this door.

The material of the door, the size of the door and the trace left on the door can be traced back to the source... All kinds of information have given Angel intuitive answers under the processing of the "server".

Sure enough, this door is fundamentally different from other doors.

Its material is excellent stone, and even the grade is far higher than the material of the building itself, which also allows this door to carry more magic patterns than other doors.

Among them, angel found at least hundreds of Magic Horn related to "reinforcement". For other doors, there may be only a few magic pattern corners similar to "tenacity" and "firmness".

That's why the door is still intact, because it's too hard.

Unfortunately, in addition to the reinforced magic pattern, which is very consistent with the stone, it has remained in operation so far, and most of the other magic patterns have been destroyed. That's why the door was opened.

However, from those destroyed magic patterns, we can see how tight it was in those years.

If it were not for the erosion of time and the impact of too many witches and ghosts, this door must be an iron wall, strictly protecting the access of the two buildings.

With such strict protection, angel became more and more curious about what the five and six floors of the building opposite were originally used for?

Through the gate, angel entered a closed corridor bridge. The other end of the corridor bridge is the top floor of the building where angel first came in.

There was no Wumu ghost on the corridor bridge, and angel came to the terrace at the other end smoothly.

On this terrace, a door stands impressively.

The door is as like as two peas, and the material is intact and strong, but other magic lines are still broken.

With a gentle push, the door was pushed open slowly.

Behind the door is a dark downward staircase.

Angel did not hesitate and went straight in. The length of this staircase exceeds the obvious space limit, which also means that the five or six floors of this building are not as large as seen by the outside world, and its interior should have been expanded.

After walking fast for about ten seconds, angel came to the corner of the stairs.

There is an open door at the corner, and a bright and wide hall can be clearly seen behind the door.

However, this is not the end of this staircase. If you continue along the corner, you will see another downward staircase.

If the space expansion is only carried out on the original floor, the sixth floor should be behind the door, and continue down to the fifth floor.

However, if the space expansion is a three-dimensional expansion not according to the specifications, it is difficult to say how many floors there are.

Angel personally thinks that the answer may be the latter.

If there are only two floors in such a tightly guarded place, isn't it overqualified?

Angel didn't go down to find out how many floors there were, but walked into the nearby door first.

He didn't forget his purpose. The first thing is to find a suitable witch ghost and let Earl confuse the shadow. As for exploration and verification, this is not something to be done immediately.

After entering the gate, there is a familiar hall layout.

Similarly, there are a lot of Wumu ghosts in the hall. The open space and a large number of Wumu ghosts are not suitable for Earl fans to complete the task.

Angel gently called "quick spirit" in his heart.

Without angel's command, the fast spirit has controlled the flowing wind and began to quickly explore the general situation of this layer of space.

Because of the fear that the power of the wind will disturb the Wumu ghost, the quick spirit controls the wind that originally flows here, which also reduces its efficiency and detection accuracy. But on the whole, it was faster than angel's own exploration.

After a long time, angel's heart came the approximate spatial distribution map of this layer given by suling.

"Is it bigger than you think?" And... It's staggered. There are many downward stairs with different heights.

Now there is no need to go to the stairs below the corner to verify. It is basically certain that the space here is expanding in the three-dimensional direction. Angel doesn't know how many floors there are. But there must be more than two floors.

Although suling has detected the general spatial distribution, angel needs to investigate the specific situation in person.

The rooms on this floor are relatively spacious, and the central room is not the current hall, but another circular hall.

All the other rooms are built around the rotunda. Including the hall in front of us.

Angel first went to the circular hall, which extends in all directions and is the best transfer station.

When he walked into the rotunda and saw the scene in front of him, angel frowned slightly.

Although it has been almost destroyed here, from some fragments on the ground and familiar metal handles, it can be basically determined that the circular hall is a laboratory.

And it's the kind of huge, open laboratory.

It's bigger than the 100 person lab we saw before.

What kind of research did nailuo city do? Need to use so many and so large laboratories, and the location of this laboratory is still so hidden?

From the debris all over the ground, angel couldn't get a clue, so he could only restrain the doubt.

The witches and ghosts in the rotunda are more concentrated. Angel carefully avoids them and shuttles through various rooms through different corridors.

After about two or three rooms, angel decided to give up. Each of the rooms here is very large. Maybe they are used for different experiments. Anyway, it's not a suitable place.

However, this layer is not suitable, which does not mean that other layers are not suitable.

According to the results of quick spirit's exploration, there are three downward stairs here. It only explored one shallowly, and two are too deep, and the wind flowing inside is very thin. Its forced exploration may attract the attention of witches and ghosts inside.

On the floor that was tasted by the quick spirit, the rooms inside are not big, and there seem to be many cubicles. Maybe you can find a suitable place there.

With this in mind, angel turned back to the rotunda, followed the quick spirit's guidance, crossed many corridors and found the first staircase.

This staircase is the one that suling has explored.

The stairs were normal height, and soon angel saw the layout of the lower floor.

Not too big room, and three corridors leading to different directions. There is a room every other section of the corridor.

It is worth mentioning that although many of these rooms were damaged and could not see their original appearance, angel roughly guessed the role of these rooms from some clues.

"Detention." Angel whispered to himself.

These rooms should be places to hold people.

Angel had guessed before that the five or six floors were so tight that it would not be a temporary prison for those criminals.

Now it seems that this guess may be right.

It's just... The lower level is the prison and the upper level is the laboratory. This design gave Angel some bad ideas.

Have you ever done a large-scale in vivo experiment here?

Angel narrowed his eyes and didn't think further. Or, I dare not think about it.

Although angel still doesn't know the specific reasons for the decline of nailuo city so far, I don't think nailuo city will be completely innocent.

There are many secrets here and the water is deep. Angel is not going to make an in-depth investigation... Even if he really wants to investigate, he is also going to the projection of Naro city in the nightmare world.

After all, there are still old monsters living here. For example, the wise man in the mouth of the day dominates.

This is just the ladder of hanging prison. An official organization in Naro city has seen old monsters that have lived for thousands of years, not to mention other places.

Maybe there are more old monsters here.

They looked coldly at the decline and plundering here, but they were indifferent and didn't even leave... Just thinking about it, they felt cold sweat on their backs. It's wrong, quite wrong.

Angel took a deep breath and pressed down the sudden fear in his heart.

Then, without thinking about anything else, he walked quickly between the prisons.

He doesn't want to know what happened here and what secrets there were in the past. The only thing he has to do now is to find a suitable place for Earl fans to perceive the state of shadow fusion

Soon, angel found the prison on this floor. There is a compartment in which six Wumu ghosts hang upside down from the ceiling for "cultivation".

This is the most suitable position Angel found.

But there are two places to pay attention to. First, there are witches on both sides of the compartment and in the outer corridor. Once they finally fight, they may disturb the witches outside. Since witches can transmit information through the shadow, they may be noticed by witches on this floor in an instant.

Second, for the first time, Earl fans merged with six Wumu ghosts. Will there be too many? Will it bear too much miscellaneous information, resulting in hidden dangers?

The best choice is two or three Wumu ghosts.

Based on the above two points, angel gave up the compartment for the time being. But it's only for the time being.

He guessed that the other two stairs that suling didn't explore might lead to similar prisons. Go to other prisons. If there's no suitable one, go back.

As for continuing to explore the stairs below the corner, or going back to the previous dark lane, angel was no longer ready to do it.

He has been away for nearly five minutes now. Although the time is not too long, he doesn't want to delay too long because of a small thing.

Now there are still two stairs, and the two quick spirits have not explored deeply, but it doesn't matter. Just know where they are.

Because he didn't know the situation on both sides, it didn't matter which way to go, so in order to save time, angel chose a nearby stairway.

As soon as he came down the stairs, angel vaguely felt a different atmosphere.

This staircase... Seems long?

Also, the smell of witches and ghosts in this staircase is very light.

There are not too many scratches and damage marks on the walls on both sides of the stairs, which seems to mean that there may be fewer witches and ghosts in it?

This is good news.

There are few witches and ghosts, so it's easier whether they fight or leave in the end.

Moreover, if the lower part is still a prison, it must be a relatively closed space. Put a blocking array at the entrance of the stairs, or directly cover it with a dreamland. Even if these Wumu ghosts are noisy, they should not affect the Wumu ghosts outside.

With this idea, angel quickly went down.

Ten seconds later, angel landed and saw the familiar "prison manager" room. It is still very shabby, but compared with other places, the tables and chairs in this room still exist, which also shows that there are really few witches and ghosts here.

In addition, unlike before, there is only one corridor here.

Moreover, this corridor is still a dead end. At the end is a wall. If you want to leave, you can only return the same way.

If it is still a prison here, the "Prisoners" once held here are estimated to be much more important than those in another prison.

This can be seen from the pattern and size of the cell.

The cells here are obviously larger, and the materials of the prison gate are relatively good. According to angel's visual inspection from a distance, he found several cells whose gates have not been completely damaged.

With anticipation, angel walked into the corridor.

Walking into the first prison gave angel a surprise. There are five round Wumu ghosts in it.

Although the number is still large, this location is good. It's close to the stairway. You can get out quickly as long as you achieve your goal.

Angel quickly forgot the cell of the previous six witches and ghosts, and gave the first place in his heart to this cell.

However, angel didn't immediately let Earl fan act. Since he came to this prison, he continued to walk forward. Anyway, this corridor is not long, and you can see the end at a glance. Maybe there are better choices in other rooms.

Facts have proved that angel's ideas are sometimes not extravagant.

Avoiding the Wumu ghosts wandering in the corridor, angel walked all the way in. Soon, he saw a room where only two Wumu ghosts were practicing.

In terms of numbers, this is better than the previous five Wumu ghosts!

However, it was a little regretful that there were also two Wumu ghosts in the other cell directly opposite the cell, and the two Wumu ghosts did not enter the state of cultivation.

If these two are also in the state of cultivation, they will be perfect. Pick any one and you can start.

But now, in terms of ranking, angel still prefers the first cell.

Shaking his head, angel went on for a distance. Here he could see the wall at the end of the corridor. It can be seen that he has come to the second half of the cell.

Unfortunately, I still didn't find anything better than the first cell.

When Angel sighed slightly, suddenly, a faint fragrance floated from afa
