Sure enough, as he continued to move forward with the light, countless scorching red lights reflected a tall wall on the right, and a large area of shaky shadows appeared on the wall, which turned into red spots of light in an instant.

The perception that is different from ordinary people makes her realize that there is a lot of breath underneath.

She originally wanted to hide herself, but she suddenly laughed secretly, now she is wearing an engineer costume, in fact, even if she appears in front of those people, it doesn't matter, there is no need to avoid those eyes at all.

In the blink of an eye, she had come to the end of the wall, and here she realized that the place she had just walked through was a passage similar to maintenance or ventilation, surrounded by metal walls, and it seemed that it had reached the end. This place is usually for those workers who work in special jobs, and the real road is further down.

Beneath her feet was the top of a hallway completely wrapped in metal, a corridor that was slightly curved and seemed to revolve around something.

This road is not working.

Joyna began to think about how to get to that hallway, looked around, and found no way down, should she go back the way she came?

After a moment's silence, her brow furrowed.

This also doesn't bother her, "If there is no road, the old lady will open a way out!" She thought to herself, and finally found a ventilation hole in the ground, which must be the hallway below.

There was a cover on the outside of the huge metal fan, and she directly broke a few locks, removed the fan, and got in.

Below was a narrow, curved passageway, and Joyna felt a crack, and with the force of her hands, the metal plate was completely torn.

The lights lit up suddenly, and when she noticed that no one was passing, she immediately rolled over and jumped down.

There is a large corridor in front of you, and the walls are all cast of heavy metal, winding like a labyrinth.

Looking back, this is the outermost point near the rock wall, and on the other side is a large row of transparent windows, bent and unstoppable, and looking very hard.

She walked quickly to the window and shuddered, and the surprising sight was on the other side.

It was an incomparably large space, with several layers of trestles stacked on top of each other, connecting a behemoth in the center.

The structure of this thing is thick and thin, like a huge cylinder, but the diameter of the thinnest is also hundreds of meters, and many buildings are scattered around it.

These huge buildings look like houses hanging in the air, except that each of these huge houses is tens of meters high and hundreds of meters long, and there are glass windows and flashing light strips inside and outside the walls.

Qiao Yinna was shocked by the scene in front of her, is this the so-called base of the emperor? A real iron city buried underground?

From this point of view, the place where I am is also a trestle of the same structure, but it is located in the outermost ring of this giant column.

The buildings connected by the trestle are not only large, but also have strange shapes.

Some buildings can still be faintly seen planting many tall plants, and some houses have roofs made of clear glass, and if you look closely, you can see countless mechanical arms and unassembled semi-finished mechs, and many people work in them, and the previous noise should be made there.

This reminded her of the sight she had seen in the Space City – a dwelling that mimicked the ecological environment. That's right, this is a modular cabin that was copied and remodeled from the "Americas".

I didn't expect that the real meaning of the ancient iron city that the emperor had painstakingly managed was this.

Joyna looked at these behemoths in the air and was stunned.

Just when she was shocked in her heart, she suddenly heard a slight footstep and talking in front of her, and someone was walking towards her. She immediately left the window, straightened her clothes, and walked to the place where she was going as if nothing had happened.

It was two people pushing a cart, dressed like engineers, with light blue stripes and off-white overalls, who were supposed to be workers or handymen here.

The two were talking and laughing, and one of them suddenly glanced at Joyna with a surprised look on his face.

Joyna was shocked, wondering why her presence had made the man look like that. But feeling their breath, she relieved herself - she was just an ordinary person, even if her identity was revealed on the spot, she had the confidence that she would kill them with one blow.

So a ball of spiritual power immediately condensed in his hand, and he was secretly on guard.

Unexpectedly, the person who saw her stabbed the guy next to him with his arm and said something, and his expression suddenly became serious. The other saw Joyna as well, and then both stopped at the same time and straightened up as they walked away.

Then, to her surprise, they saluted her.

A big stone fell to the ground in Joyna's heart, it seemed that they had recognized the wrong person, obviously they were dressed well, and they probably thought they had seen a superior supervisor.

Joyna nodded at the two of them with a calm expression, and walked past them without hurrying, and in the moment she passed, she seemed to feel a slight change in each other's expressions.

"Huh? Oops! These people should have their own way of greeting each other, and they were careless just now, maybe they should salute them too, right? ”

Joyna's mind moved, and she suddenly turned around, and the two of them saw a chilling murderous intent in their eyes at the same time.

She didn't give them a chance to react, she had an extra handful of frost in her hand that condensed into a thin slice, and with lightning speed, she silently pressed the dagger to the carotid artery of one of them, and the cold air immediately invaded the guy's whole body, turning into a corpse without saying a word.

Before the other could react, Joyna choked her by the neck, staring at her with wide frightened eyes, and her whole body was extremely stiff.

"Don't shout, or break your neck! Tell me, what is this place? ”

"Don't, don't kill me, this is our base."

"Base? Where did those guys come from? ”

"What? I don't know what you're talking about...... What kind of guys? ”

"It's the kind of soldier who exudes heat all over his body."

"I don't know about that...... I'm just the one in charge of the transport......"

Joyna added a little force to her hand and covered her mouth.

It wasn't until the last moment that the guy read the other man's meaning from Joyna's eyes, and she didn't even want to get an answer from her own mouth.

Joyna's shot was very measured, "click"! The poor creature had a comminuted fracture of his neck, and without a snort, he collapsed to the ground with his head tilted.

She let him go with ease, slowly flattened him, dragged one with one hand, and threw it onto the cart like two rabbits. Looking around, there was no place to hide, so I had an idea and stuffed the two guys back into the ventilation duct where they came.

With that, she disappeared into the dark hallway.

Since this place hides so many secrets, why not take this opportunity to explore them?

Obviously, he came to the right place, which can be said to be the most secret place in the ancient iron city, the huge arsenal hidden in the air fortress.

She didn't know if the emperor was somewhere else, if there was a factory of this size, or if the laboratories that made powerful warriors were hidden. But one thing is certain, after finding out this place and getting information, it will be of great help to understand the strength of the opponent and disrupt their attack, and it can even be said to be strategic intelligence that will affect the situation of the battle.

What is hidden in those sprawling buildings on the other side?

How were those terrifying warriors made?

And where does the power source of this floating fortress come from, and what is the distribution of weapons and equipment? What are the weaknesses?

These are all secrets of secrets, and knowing these things will be the key to her victory.

This made her feel incredible, those former civilizations had been restored so thoroughly, it was not enough to rely on decades of hard work, that emperor must have collected a large number of capable people.

Another thing that she found incredible, and crucial, was that she felt subtle changes in her body, and the reason was that the force field here was very strangely distributed. As early as when she first entered the passage, she always felt that something was pulling her body, and her originally sharp sense of distance was also very unstable.

When walking on the road, it feels light and fluttery, and then it is slow.

She felt that her wings were probably not of much use here, and that the spatial force field here was very disordered, interfering with her ability to fly.

It seems that there is some gravitational pull at work in all directions, and I just feel like I have a mountain on my back, and my body is heavy. And as you go deeper, the feeling gets stronger.

Joyna looked all the way and saw that some of the rooms were locked by gates, and there were tracks on the floor and ceiling. She used her senses slightly and immediately found out that there were miscellaneous equipment and materials stored inside, and there was no one else, it seemed to be a warehouse.

Moving on, she hesitated at a fork in the road, and there were three paths in front of her, two of which seemed to lead in a parallel direction, and the other a staircase that led to the lower part.

What to do, where to go?

But so it was just a moment of hesitation, time was pressing, and the longer she stayed, the easier it was to expose herself, and she didn't want to waste time.

So she walked quickly to the huge curved glass window and looked out, some strange arcs of electricity, emitting white light in the dark depths like the abyss beneath her feet.

Those criss-crossing passages stretched through the air, and her goal was to get close to the giant pillar in the center, so the route was clear, she was going to take a straight line.

Based on the depth, she was now seventy or eighty meters underground, and she felt that she should be in the center of the entire floating island, that is, below the Imperial Castle, with an error of no more than one kilometer.

Without much thought, she waved her hands on the glass, and a layer of crystal frost immediately covered it, and then, sharp bone spurs grew from her forearm, and a beautiful arc slashed, and a circle of thin scratches appeared on the whole glass.

With a gentle push of his hand, countless cracks appeared under the tremendous pressure, and with another force, there was a "bang", and the cracks condensed on it by the frost turned into a large mass of tiny crystals, falling into the pitch-black abyss.

Joyna jumped a distance of tens of meters with the flying sand, and fell along with the crystals that shone and flew in the darkness.
