The huge town hidden in the clouds gradually revealed a complex and indistinct outline, and the clouds that obscured it began to recede from the farthest point of the sky.

The huge figure moved slowly against the backdrop of an even larger, cold, gray moon.

The double shadow plunged the place into a completely dark world, and the people on the ground were already numb to the frightening of the successive visions, and the rumbling sound came from far and near, and everyone's ears seemed to be tens of thousands of elephants rushing by.

The treacherous clouds floating above the behemoth in the sky are not at peace at this time.

"Uh-huh——! Finally found it for me, this should be the place, right? ”

After a few super jumps, Joyna had climbed the castle's central control tower.

Several thick searchlights swept by, almost in a hidden position, but fortunately she was calm, her body was motionless, and there happened to be a shadow in the gap where she was hiding, and she could avoid the light.

Joyna looked up and knew it wasn't directed at her, but something else.

She prostrate on the outer wall, slowly but carefully adjusting her breathing, her fingers clasped between the transparent glass wall and the metal panel, and turned slightly sideways to look inside the building.

It is the bottom of the ring of towers that connect countless passages, and all the buildings inside are brightly lit.

Joyna roughly estimated that the diameter of the circular passage must be more than six hundred meters, and the area was more than four football fields, but it was so dark that there should be an abyss several hundred meters high.

She gently twisted open a crack in the metal wall, removing an entire panel and burrowing into it without anyone noticing. She was shocked by the sight in front of her, which was simply a complex labyrinth of many mechanical equipment, connected up and down, divided into several layers, with a total drop of more than 60 meters.

She looked up and saw what appeared to be some massive connecting rod connecting the several modular passages around it. The power control and energy output units are supposed to be hidden in it, and this design is completely copied from the "America", and even the layout and basic structure of the rooms are similar.

Because of this, Joyna knew that the central core should be surrounded by a ring-shaped cabin, which is the room seen now.

And this location, according to her speculation, is at the core of the Imperial Fortress, the lowest part of the castle, about 170 or 80 meters deep.

This space and height are enough to fit a skyscraper of nearly 100 floors.

It's just that Joyna doesn't understand why this "Faceless God of War" must lift his castle and the entire city into the air at an altitude of 10,000 meters?

Regardless of the unrest that was taking place outside, it was clearly unaffected: orderly intelligent machinery took turns transporting all kinds of materials; Giant hoisting arms are busily welding delicate culture tanks; Conveyor belts and robotic arms assemble equipment parts from a variety of materials; Countless guards armed to the teeth patrolled; It seems that there is still a surplus of power here, which can provide sufficient energy to some intelligent manufacturing equipment.

Soft white lights flicker from top to bottom along the central core, representing the momentum generated by the energy, which is running steadily inside it.

Joyna guessed that there should be a nuclear power chamber or nuclear furnace hidden here, because she could clearly feel the constant energy reaction, and the temperature was much higher than outside.

When mankind first opened the Pandora's box of atomic energy, he has been obsessed with this magical power. But later people knew that this was not only an inexhaustible treasure trove of energy, but also an invisible weapon to kill people.

Therefore, pre-civilization human beings gradually abandoned the use of this energy source as a direct driving force, and then studied its potential in other fields, and replaced it with research in the direction of bioenergy technology and light energy.

But in this day and age, who will have the leisure to care about these things?

The emperor had clearly excavated the product of an ancient era, and then at his command, countless researchers began to restore what had been discarded by the old era, bringing this energy source back to the stage of history today.

In Joyna's view, there was nothing to blame for this attempt to cover the sky with one hand, and at that time, there were still many scientists who spared no effort to preach the bright future of nuclear energy.

Just as the lies of the false gods even blind the sky, but in the end they will be opposed by another group of wiser people, and the reaction of the masses of people will also determine its future, which is no longer a dispute in the field of science and technology or research, but a matter of human morality.

At that time, people also took a long detour to study this energy source, and countless scientific researchers even contributed a short life, but in the end, people gave up the idea of further practical use.

But the course of civilization is always so similar that, when the conditions are ripe, there will definitely be people who pick up the drawings thrown into the historical garbage heap and study them as treasures.

What's more, in such an age of lawlessness?

Until this moment, after seeing the laboratories here, the equipment factories and countless busy machinery and workers, Joyna had a deeper understanding of the imperial ambitions of the ancient iron city.

"Buzz ......"

The sensor on her arm shuddered suddenly, and the light in the air changed, and it seemed that a young figure was appearing in the halo.

"It's the master!? Have you, your body recovered? ”

Joyna was surprised to see Zhuge Yun's face appear in the light mist, and she was so surprised that she almost cried out.

"Where are you?" Zhuge Yun spoke lightly.

has been dominated by suppressed emotions for a long time, although she already knew that the master would come back after that spiritual journey, but the moment she saw Zhuge Yun come back, her inner emotions were truly released.

The host is really back!

"This is the fortress of the emperor, in the heavens...... Giant floating castle. Joyna found a hidden place and continued to communicate with Zhuge Yun.

"Hmm...... I see, so he got Space City's anti-gravity technology? What are you going to do there? ”

Joyna quickly gave a brief account of what had happened and asked him about his health.

But Zhuge Yun just warned her to be cautious and said, "Don't die." He didn't say anything more, it seemed that he had more important things to attend to.

Joyna turned off the communication, and her heart fluctuated for a while, only to feel that a big stone in her heart suddenly fell, and she was much more relaxed. She knew that as long as the master returned, with his supreme power, there was no problem that could not be solved!

Soon, the sight before her pulled her back to reality: she must find a way to seize control of this place. Even if you can't let it land safely, you can't let it fire that terrifying cannon.

Just as she was thinking about how to find the main control room and hold those operators hostage, she suddenly heard another noise above, and the chaotic footsteps accompanied by human voices, as if something had happened in the upper space.

She looked up and saw that several huge mechanical arms were carrying supplies back and forth on the upper conveyor belt, and it was not difficult to jump up from here.

There was a circular corridor leading to the central patio, and Joyna guessed that there must be a way up there. So she jumped directly onto the iron frame, jumped in the air, landed on the other side of the mechanical arm, and then moved almost vertically against the mechanical arm, and from there she fell to the wall at a rapid speed, and continued to climb along the wall.

"Da Da Da-"

A burst of gunfire caught the attention of all the guards here, and the ceiling above them trembled.

The sound of howls and the fierce gunfire mingled to what seemed to be a big battle above.

Joyna waited patiently for the moment, but it was now......

"Tick ...... Tick ......"

Joyna suddenly felt something wet dripping onto her body.

With the help of the not-so-bright light, she lightly touched it with her hand, and then looked at it, the tentacles were sticky and wet, and it turned out to be blood!

Red blood had already stained her combat uniform, and Joyna was taken aback, and trickling blood continued to gush out of the cracks in the metal exhaust pipe above her head, and she immediately unscrewed a steel plate directly, jumped reflexively, and jumped into the ventilation hole.

There was not a small space in the ventilation duct, and Joyna walked a few steps forward along the bloody water, and heard several screams, which were quite miserable. Blood was pouring in from the drain above, and she pushed open the cover above her head and poked her head out.

A hideous face jumped into view, chapped lips and eyes were wide open, fingers tightly clasped around the body of the gun, and the smell of blood was extremely unpleasant.

It was the corpse of a dead soldier lying on the ground, as if it had been cut by countless sharp blades, and blood continued to flow from the wounds on his body.

Presumably, he must have been quite painful when he died, because Joyna saw a long blood mark behind him, which seemed to have climbed a few meters, and finally couldn't stand it because of too much blood loss, and then he was completely dead.

What made her even more puzzling was that this soldier still had an energy she was familiar with—the power of black evil, and she saw that there were already some blackened marks on the cut wound, and the blood had turned purple and black, and the feeling of that energy was extremely real.

Could it be that the Obsidian Hunters guys are here too?

Joyna quickly emerged from the passage and cautiously ran towards another irregular chamber, the lights flickering on and off, and the sound of electricity ringing out of nowhere.

Along the way, I saw dozens of soldiers who died tragically, almost in the same way as the poor fellow, his body was cut in a mess with sharp weapons, and one soldier had his carotid artery severed, his head tilted to one side, and his sinew was still attached to his skull.

In front of it was a heavy hatch, made of unknown alloy, and the blood stains were gone here. This hatch is almost seventy centimeters thick, and behind this door, less than thirty meters in front of it, there is a huge biological energy induction.

With her superior over-range sensing and ubiquitous intricate cables, she knew she had found the right place – the main control room for the entire Flying Fortress.

Joyna leaned against a wall, holding her breath, her muscles tensing and feeling the tremor of the metal.

"Bang Dang ——!"

"Boom!"

She was startled when she heard the sound of a fight coming from the other end of the wall.

Who is the base here?

"Please...... Help me——! At this moment, a faint sound suddenly came from the small door of the other party's miscellaneous objects on the side.

Opening the door, Joyna saw a man in a helmet huddled in a corner, shivering, the helmet looked like it wasn't his own, and even the goggles were upside down, just symbolically fastened to his head.

"Who are you? What for? ”

When Joyna gently pushed away the debris, she found that one of the man's arms had been cut off in unison, the wound was wrapped in a rag, and the other hand was covered in blood.
