On the walls and floors, everything in this space was dyed scarlet, and after more than ten seconds, all the "exterminators" were swallowed up by the invisible blood mist, and even those who had escaped could not escape the doom, and were soon caught up by the spikes turned into "thorn whips".

However, the high-energy explosion that Joyna had expected did not happen.

The uncontrolled blood spikes had already turned most of their energy into blood food when they pierced their bodies, and that invincible speed could not leave any "exterminator" a chance to fight back.

Everywhere were the terrifying howls of those "Exterminator" test subjects, the creaks that pierced through the metal, and the hellish killing sound for tens of seconds resounded throughout the upper laboratory, and it was definitely a feast of slaughter.

The "exterminator" eventually became the "exterminated".

"Nope! Stop—stop! Joyna's inner voice erupted and she began to roar unconsciously.

A scarlet glow also appeared in her eyes, and the surging blood took over her vision, and everything was red.

I don't know how long it took, and the restless mood was gone, replaced by coldness, cruelty, and silence around it. In the dark, she saw a red figure again, as if smiling at herself.

The entire petri dish equipment in the lab was violently destroyed by her, and no matter what kind of "exterminator", complete or incomplete, and even those who didn't have time to get out of the cabin, they were all eaten by bloodthorns......

An endless sense of power filled her body, and Joyna only felt that the sea of qi was surging, and the energy that was forcibly poured into her body changed her genetic sequence, and the powerful energy feeling made her omnipotent at the moment. Unconsciously, as soon as she raised her hand, she slashed out a bloody light, and a huge hole appeared in the metal wall of the laboratory, almost dozens of meters in length.

The guards on the lower floors had already heard the loud movement, and some people kept shouting, and some people were running quickly. But the chaotic footsteps soon dissipated, and these people were so distressed by the destruction of the iron ladder that they could only go around to the other side of the building and try to take the elevator up.

At this moment, Joyna's heart was extremely complicated, full of inexplicable dazed emotions.

Grief, anxiety, confusion, and the callousness to follow instinctive desires.

Not for the "exterminator" subjects, but for herself, who felt like she had become an uncontrolled monster, an instinct to devour that came out of nowhere, and that seemed to hide an untamed beast within her body, a beast that made her tremble both physically and mentally.

It took her a long time to come to her senses as she looked at the liquid and the ruined equipment on the floor, at the torn clothes on her body and at the arm that had spiked out. There are thirty or forty "exterminators" here, but almost all of them are turned into their own food in an instant, I can't believe it, could it be that she did all this?

The evolution of genes has given her powerful abilities, and correspondingly made her carry heavy shackles, and what is even more terrifying is that she feels that this body has something that has not yet awakened, it is not her own power and consciousness, it is a desire that she cannot control.

She must wait for her master to come back, and if she can get an answer from him, she wants to know what it is. What happened in just a few tens of seconds made her heart violently shake, and even she didn't know when this ability was conceived?

Why did you do these things when your behavior was uncontrollable?

She stood dumbfounded, hearing the ticking of liquid dripping to the ground, the liquid dripping from her fingertips, and at this moment, it was as if everything was still, waiting for her decision.

After being stunned in the dark for a while, she realized that there was still unfinished business, and she must find the emperor of the ancient iron city and explore the root cause of these strange events.

As the electricity and light in the lab dimmed, she didn't have the heart to stay in this place anymore, and hesitation wasn't her personality. So without looking back, he walked straight to the opposite wall, gathered strength with his arm, and smashed his fist on it.

After a loud bang, the entire laboratory trembled, and the already cracked wall was smashed into a large hole, just enough for one person to pass through. She quickly tore through the wall and jumped straight out.

After several astonishing jumps in a row, she stepped on the steel beams and the roof of the building, leaped upwards for more than ten meters, and landed on the top of a main passage.

Comparing her small figure to this huge space, it was like a speck of dust floating in a gymnasium.

Although this place is huge, after all, it is only the belly of the Emperor's Floating Fortress, and it still has a visible margin.

The buildings around her, far and near, were dotted with stars, and the entire floating castle had been hollowed out by the emperor in order to fit the entire sprawling base. Vehicles laden with materials pass through the chaotic and well-connected passages, and some buildings have countless track facilities on the roofs, and sealed mining trucks are full of materials. Someone commanded at the entrance, and more passages connected to some assembly plants, which appeared to be assembly workshops for mechs and vehicles.

But at the moment, Joyna no longer had any interest in exploring those places, this kind of mecha she had seen elsewhere, and all the weapons and equipment systems were not necessarily more advanced than those of Mine City.

One thing that made her pay a little attention was that on the top of the huge factory, she saw the flight deck appearing, and among those mechs was a model with wings, which seemed to be manned.

This thing is about the same size as the giant drone in Mine City, and it shouldn't be a problem to have two pilots on it, but the lower body is modified from an ordinary mecha, assembled in pairs, and tires replace four mechanical legs.

For a more stable form, the fuselage seems to be welded together, and it does not use the bionic structure of the four-legged chariot in Mine City, which looks very perfunctory, but the various heavy weapons equipped on it, such as the multi-barreled cannon, are genuine things.

Joyina's gaze didn't linger too much on the machine—these mechs didn't sound good, they were just a pile of scrap metal in her eyes.

It is quite powerful against some ordinary soldiers, but it does not pose an effective threat to Mine City. If you install a smart chip, you don't have to worry about anything, and it should be easy to do it with the powerful ability of Dongfang Road.

There is nothing more brutal in a ground war than street fighting in the city, and the real threat is the huge ground legions.

The mecha-driving corps and the invincible soldiers in the eyes of ordinary people - the "exterminator" are the headaches, but the latter is almost gone, and it has all become its own blood food.

Although Joyna didn't know if the emperor still had petri dishes and laboratories elsewhere, it was almost impossible to create another group of terrifying soldiers in a short period of time, which also indirectly delayed the emperor's attack.

She looked down at the substructure from a high vantage point, and soon saw that as far as the eye could see, there were strange curved buildings scattered around the perimeter for kilometers on the edge, and around their outer layers were many outbuildings.

Complex mechanical structures loomed over it, thin lines of light that seemed to move regularly around the building, flashing countless halos every few seconds.

Just looking at the exposed part of the outer wall of the curved building, it is estimated that its diameter should reach several hundred meters. She felt the tremendous energy emanating from those places, and it seemed that their interiors were the driving force behind the floating castle.

She thought as she ran and jumped as fast as she could, creeping up like a spirit dancing in the dark space, creeping up on one of the curved buildings.

The distance getting closer and closer made her body lighter, and within the last few hundred meters, she felt that her body was light, her wings were outstretched, and she was already able to fly in the air.

"That's right...... It's that weird force field! It's from these buildings. ”

Joyna finally figured out why, and she saw a lot of mechanical devices like conveyor belts, with minecart-like transports on them, constantly transporting supplies to the buildings, but the carts were covered by metal covers, but the distance sensing made her realize that there should be ore and muck inside.

After thinking about it for a while, she understood that the place in front of her was the most critical and important part of the floating fortress, and it was also the most technical place - the gravity engine.

"Heh—sure enough, I found the weakest point of the Flying Fortress!" She smiled, but after a few seconds, her brow gradually furrowed.

She also saw two large metal rods sticking out of the bottom of the ring, but the discovery gave Joyna goosebumps all over her body, and she recognized the thing—the main naval gun that had been installed on a 20,000-ton megaship in pre-civilization, a super-electromagnetic cannon that could shoot energy that could evaporate nearly a kilometer of land in an instant......

Therefore, each gravity engine not only has the function of providing flight power, but also can use the remaining energy to launch a powerful energy weapon to the ground, which is probably the real deterrent power of the floating ancient iron city.

If this place is destroyed, the entire floating city will lose power and crash to the ground. If this tonnage behemoth falls to the ground, its power can be imagined, and it is only afraid that a radius of hundreds of kilometers will be destroyed under the impact of huge kinetic energy, and the mining city is of course among them, and hundreds of thousands of people will die as a result.

Also, she saw that there was not just one of these massive devices, but they were evenly distributed and seemed to be activated in turns. Theoretically, almost half of the power engines are running normally, so that the floating city can get enough power.

Through observation, there were about a dozen of these buildings she saw just now, not to mention that they were all destroyed, even if only one was destroyed, it was impossible for the Mine City to have such a powerful weapon.

There is a huge threat in front of her, how to solve this big problem?

Joyna only hated her lack of strength. If the master is here, he must have a way to solve the crisis in front of him.
