Without any time to think about it, Joyna reacted faster than that machine.

Before a loud beep sounded, a blast of cold energy shot out of her hand, instantly freezing the machine, and then she leapt to her feet, slicing a beautiful arc through the air, severing the cables attached to the wall with lightning speed.

Joyna didn't dare to stay for a long time, for fear that someone would find out that the mechanical paralysis was artificial, so she kicked her feet against the wall and landed on the opposite roof.

As she continued to walk, Joyna noticed some buildings that were noticeably different from the others, and these slightly taller buildings were equipped with this infrared thermal device.

If an ordinary person is detected, the alarm will definitely be triggered.

Although Joyna didn't know how this thing could distinguish between its own people and its enemies, Joyna had changed her body temperature, and now it was almost the same temperature as the cold masonry of the building.

Two patrolmen with half-masked mechanical helmets on their heads leaned against the corner of a building smoking cigarettes.

Although the tobacco control in the ancient iron city is not as strict as other rules, tobacco belongs to the scope of luxury goods that are controlled, and it is enough to be caught.

The two patrolmen took advantage of the fact that no one was around, and they huddled in the corner, also to avoid people's eyes and ears, and secretly enjoyed a bite.

There was a sentry entrance and exit behind them, and the supplies in this area had basically been loaded and unloaded, but they had not yet received the order to leave.

One of the guards leisurely exhaled thick smoke, tilted his head with his neck high, and gently fanned his hand in the air.

As soon as he looked up, he felt that something seemed wrong.

At a glance, it seems that I have seen something that does not belong here. However, the sensor on the helmet shows an unchanged curve.

But he always felt that something was wrong that could not be explained, so he withdrew his gaze and looked again at the roof opposite, and by the moment his gaze fell on Joyna was no longer there.

"Damn, I may not have slept well in the past few days, I'm always nervous, I'm about to have a nervous breakdown!"

"Not that exaggerated, right? I think you have a fear of heights or dyspnea, and I wish you could go down quickly! ”

Another soldier laughed at him as he also puffed a puff of smoke from his mouth.

"Forget it, I don't want to go down to be cannon fodder, if you want to go, you should go!"

"Haha, there will be a war soon, it is said that there are some powerful people in the mining city, just like the black guys with wings, and I don't know where the nobles spent a lot of money to hire mercenaries."

"Humph! Count it as a p, don't say anything to destroy your prestige and ambition, even if there are powerful mercenaries, it is impossible to stop those exterminators and steel mecha troops! ”

"When our emperor rules there, it is said that those who survive the battle will receive a rewarded land, which is still hereditary!"

", are you an idiot? There's no way a soldier like us can get anything! ”

"Hey, so...... It's better to stay in the city honestly than anything else! ”

Suddenly, his expression froze.

It felt as if something had vanished out of the corner of his eye, and he felt a chill run down his spine.

With a click, half of the cigarette in his mouth fell to the ground.

The soldier on the opposite side opened his mouth wide, and watched in horror as a transparent object protruded from the chest of the soldier who was laughing at him, crystal clear, it was actually an ice thorn?

Soon, another ice pick appeared on his right chest, stained with a scarlet blood line, then two, three...... It converges and drips down the tip of the icicle, but quickly solidifies.

In surprise, there was also a burst of ice on his chest, and he didn't have time to turn his head to look, only to hear "Poof!" next to his ear. With a bang, the soldier in front of him fell.

As the lungs were pierced by the cold, the spasms caused the muscles to contract violently, turning into a fist-sized, and the rapidly generated ice slag filled with blood, which not only made it difficult to breathe, but also made it impossible to make a cry.

Cold sweat ran down the soldier's forehead and spine, and he opened his mouth but could not make a sound, his eyes wide in fear, desperately trying to see his attacker.

Joyna's cold hand gripped his neck tightly, and with the other hand under his ribs, she dragged him directly into the path next to the building, where she was still on the ground with a flick.

The soldier took a hard breath, only to feel a cold patch in his left chest, the punctured part of his lung was frozen by his own blood, and it no longer bleed, and the wound was filled with a little less heart-rending pain.

Joyna knew that he would not be able to die for a while, and that she had left an intact lung for the other party, just so that he could still speak.

But the slightest movement of his lungs will leave irreparable damage, and he wonders if the sealed blood will continue to flow out. Therefore, he maintained a hard-working posture with his upper body half-raised, and his stiff arms slightly supported his body.

"What's underground?" Joyna leaned in and asked in a low voice.

Is it the enemy? Although the frightened soldier couldn't raise his head, his heart trembled when he heard the voice of a woman.

Unexpectedly, floating at an altitude of tens of thousands of meters, the impregnable ancient iron city was invaded by the enemy?

"It's ...... base"

"What kind of base?"

"It's the emperor's...... Combat department, and ...... Lots of room...... I don't ...... either."

The soldier's mind was filled with fear, his voice was weak, and his speech center seemed to be less sensitive.

He tried his best to keep his body steady, but the blood in his chest was flowing silently, putting him under great pressure, and his brain was drowsy, and he was on the verge of collapse by struggling to die.

"Huh?" Joyna's brow furrowed, and she flipped him over on her tiptoes.

The soldier finally saw the face of the enemy.

His eyes reflected the delicate face of a red-haired woman, unbelievably bright, looking at himself against the background of a blue sky, half of his face hidden in shadows, and a faint multicolored streamer behind him.

The soldier's heart trembled, and his consciousness was somewhat blurred.

Are you going to die? I don't know if it's a ghost or an angel. If this woman was sent by the enemy, how did she get here? Did you sneak in here when the ancient iron city landed for supplies?

"Where is the entrance to the Emperor's laboratory, let's talk about details." Joyna's voice was as cold as an ice pick on a soldier's chest.

"Hmm......," the soldier groaned.

She allowed the icicle to slightly prop up the skin around its wound, and though the section had only expanded by a few millimeters, it was enough for him to feel it.

"It's all confidential...... Department...... That's all I know about my permissions...... Don't kill me...... Not! ”

The soldier's stunned expression froze instantly, and his head slowly tilted to the side, completely dying.

Joyna didn't feel anything special about these soldiers, they were just ordinary people, and they didn't have the energy of mutation, and those so-called enhanced soldiers who were genetically tuned should only be a small part. If she guessed correctly, they were made in a lab or some secret location, and she had to find that place.

She let go of the hand covering her mouth and nose, looked around, and found a metal manhole cover. Below it was supposed to be an underground ditch in the city, so the two corpses that had been frozen into ice mounds were laid flat, lay inside, and re-covered them.

She quickly left the area, crawling from building to building like a gecko, hiding through the gaps and looking for an entrance.

The streets of the town are lined with old street lamps with wrought iron ornaments; Flower beds and boxes of plants are displayed in an orderly manner; In front of the building, where several colors are mixed, there are more or less some fences and gardens in front of the house; The masonry of the ground is brownish-red and beige, and the roadbed is paved with pebbles of various sizes, everything looks like a scene copied from a harmonious medieval European town.

Joyna even had some approval of the emperor's taste.

Human memories are limited, but childhood is unforgettable and beautiful. From the top of the house, the town was so peaceful and lovely, and after a few minutes of quiet time, she was in a trance.

There was a sense of familiarity that made her almost forget her mission - because everything in front of her was like the place where she lived as a child.

If it weren't for the transport vehicles, bipedal machinery and busy workers loading the goods, she would have thought it would be a quaint and well-preserved town.

Perhaps because of her sensitive teleportation, or just a bit of luck, she soon discovered the entrance to an underground base hidden in a building.

A brand-new car, unlike the other cars on the street, pulled out of the basement of a building, and then the ground gate slowly closed. Several of the people in the car were wearing special hazmat suits, and when they got into the car, they took off their hoods, looking like researchers or doctors.

The building didn't look anything special from the outside, except for a small mark stamped above the lintel, a golden trident, and Joyna immediately remembered the Medal of the Iron City that the ghost had given her.

It was awarded by the emperor and awarded to those whom he recognized.

Except that it can't be pinned to the chest, everything else is exactly the same.

She knew immediately that there was probably something she was looking for in this building.

It only took a few seconds for Joyna to tell that there were no guards around the building.

In this city, the guards are like police officers, not to guard against the enemy, but to punish those who do not follow the rules, or to work hard enough—delaying the transportation of war supplies, but punishing heavy fines.

Sure she wouldn't be discovered, she leaped onto the roof and jumped directly into the courtyard from the balcony on the third floor.

Just as she was about to take a look around the room first, a strange sensation came from her body, and it was above her head.

She immediately pressed against the cold wall, adjusted her breathing, and looked up.

I saw two black figures, flying into the air from a dark corner where the sun could not shine, about a few hundred meters away from her, the silver reflection flickered, as if they were wearing battle armor or something.

Joyna narrowed her eyes, and with a slight recognition, she quickly recognized the two same guys who had led her out of the base at night when she was attacked by the Obsidian Hunters, with black wing membranes, mutants known as the Screamers.

"Sure enough, that emperor and the obsidian hunting regiment are secretly colluding!" She held her breath and thought to herself.
