I'm a monster in Demon King's Castle

“Level this city!”

As Jessie uttered her vow, she resembled a king descending upon his domain.

Accompanying her declaration, one side of the scales suddenly plummeted while the other soared—the ascending starry sky traced bizarre patterns, as if a heavy stroke had been painted across a canvas.

That stroke's color pressed down upon Jessie, her flames and mirrored light gradually cleansing the yellow-green of Green Lake and the sandstorm, becoming as pure as the starry sky.

Immediately following, her face and armor gradually became smooth, reflecting dazzling light, as if transforming into a mirrored aggregate.

“I am… the Mirrorflash Knight.”

Jessie's aura also became exceptionally terrifying.

Li Yue watched the sky behind her, sensing everything happening to her, and realized that this hero also had a deity behind her.

That was a miracle.

Clearly, like the demons, when a hero's stage ascends to its peak, they also have the opportunity to glimpse a deity.

“Huh?” Copper Ladle compared the angles of Tom and Tank, blowing his whiskers at Li Yue.

However, a palm stretched out from the pillar of fire, steadily catching the ice bullet.

Symbols and words interfered with Tom's mind, and the mirror behind Grandet was instantly filled with shadows, reflecting nothing at all.

Mirror after mirror divided the desolate land, gradually forming a gigantic mirrored maze.

Temporal rifts emerged behind the vow.

Heimer was separated from the library's other creatures by the mirrors and his companions, unable to find them no matter how far or fast he fled.

The Tom in the sky was still absorbing the power of the vow, constantly growing into a thicker pillar of fire.

Tom began to transform into a dazzling pillar of fire.

Jessie had never seen this kind of technique before.

The sound of shattering mirrors.

Under the interference of the ripples, the scales of the vow were no longer so clear, and the part weighed down by Tom's vow gradually lifted.

“Fire!”

“Is that all you have…?” Tom asked.

“Snap!”

Why could she say that deity's name?

The "Vow" behind Jessie… should be the God of Knights, right?

They knew Liang Shunqing was the library's skin, but they weren't sure who was inside, or whether it was worth saving—if it was a brain spirit, wouldn't it be fine if it died?

Jessie even filled her body with lava left hands, fighting fire with fire, her whole person like a walking chimney—anyway, the lava left hand was a sensory object and wouldn't directly harm her.

Li Yue muttered.

Symbols in the air wound into a passage, and down the passage Heimer's ideal country slid towards the pillar of fire.

Tom opened his arms, and the fire wings he released re-condensed into the shape of scales, then headbutted the ideal country!

“Bite your dwarf butt, and blow you up!” Delaying for a moment, Copper Ladle of course assembled the Copper-0 Tank, firing a shot at the burning mirror surface.

They gathered together, becoming ripples spreading across the desolate land, echoing something behind the vow.

The Seven Little Generals connected, Grandet concealed his tracks in the moonlight, constantly opening doors, heading straight for the sky.

The flames pouring out of Liang Shun's body covered the mirror, and the Grandet reflected in the mirror instantly billowed white smoke, his whole body plunged into a sea of fire.

The symbols deepened, flowing between Tom's palm and the muzzle of the cannon.

A bloody hole appeared in Tom's chest, but he still chanted his original intention.

The words and symbols disappeared together, and the ideal country returned, preparing to aim at Tom's head for another fatal blow.

“Ha, so he has a god behind him!” Even though Heimer was about to have his brain burned to a crisp, Jessie still laughed with buzzing sounds, and the ripples emanating from the vow suddenly intensified, until they were dragged back into the sky by those words.

Liang Shunqing was looking at a broken mirror, the mirror showing his burning reflection, while the version of him in the mirror constantly emitted white smoke, with lava left hands flowing from his orifices.

“Level this city, starting with him…” Tom slowly descended, the fiery clouds in the sky tumbling and stirring the broken mirrors, gradually gathering around him.

And Jessie was still running within the mirrored maze.

Then, she was pierced by the ideal country.

In the blink of an eye, the ice bullet traced a nearly straight line.

【Break them…】

“Aim accurately, there's only one ice bullet.” Li Yue reminded Copper Ladle, and incidentally unfolded a void page for him.

On the page were meticulously calculated angles and ranges.

“You! Come help!” Liang Shun stretched out his binding lines, instantly grabbing the Seven Little Generals, connecting them to the shadow brain behind the cerebrum.

Jessie awakened.

“Level this city!”

Although she briefly endured the flames from the mirrors, Jessie had nowhere to go.

After fleeing with the cult, only Li Yue and the library's gladiators remained in the arena to face the knight Jessie, empowered by the "Vow."

“My vow… level this city…”

Jessie ascended into the sky, taking the remaining power of the library with her.

“Pop!” The ice bullet was crushed, becoming a snowflake in Tom's palm.

At this moment, Aka's magic power was empty, clearly unable to be used to fight Jessie, Wang Mu chased Little Wolf everywhere, and Shadow and Egg Egg were both forcibly conscripted to the bone chariot cult…

“Should we save him?” The Seven Little Generals were unsure.

Although the ice bullet was gone, the snowflake remained, and connecting the snowflake and the muzzle, some simple symbols and patterns suddenly appeared.

The new knowledge generated by Jessie concentrated together, bringing inexplicable ripples and thrust.

Could she be stronger than me?

Immediately following, the brain-1 prototypes of the Seven Little Generals also suddenly surged with words and symbols, then not Garalac's bone armor, and finally every pore and binding line seam on Grandet's body.

The twin moon blades reasserted control over the eternal night above the arena, closing the distance within the drawn starry curtain, seemingly wanting to mend the sky filled by the vow.

At the same time, doorframe traces also appeared in front of Copper-0 Tank, Garalac, and Kakarot, directly covering them…

The cannonball passed through, causing no damage.

And at this time, Tom very much wanted to look back, and the pillar of fire gradually straightened and dissipated.

The weight of the flames drastically increased.

Everywhere in the maze were Jessie's reflections, everywhere you could see yourself, but no way out.

Jessie focused all her attention on Grandet, and the surrounding space began to become rough, Grandet's face emerging.

“Time…”

“Let me out…” Little Harry propped himself up on the top of the driver's seat, pried open the lid and crawled out, then pulled out his spine, directly propping it against the bottom of the tank, propping up a high firing angle.

The ideal country swung countless lava left hands, dragging shadows and white smoke, like a rocket about to break through the pillar of fire.

This was a blow of knowledge.

At the same time, the mirrors began to burn.

That light illuminated the arena, and also illuminated the eternal night of Demon King City.

Compared to it, the twin moon blades also seemed unusually dim.

Jessie shattered the mirror in the first instant, attempting to escape, but every shattered mirror reflected Grandet's figure even more diligently.

And in the eyes of the Seven Little Generals, scholars, craftsmen, and skeletons, Liang Shunqing suddenly froze.

These were the design blueprints that the Copper-0 Tank had undergone from its initial design to the present, as well as the constant day and night calculations and computations by Liang Shun, Copper Ladle, and Harry.

“Fire!” Copper Ladle stepped on the mechanism, and the ice bullet shot out of the barrel, heading straight for the pillar of fire in the sky.
