The Royal Military Academy's Impostor Owns a Dungeon [BL] novel Chapter 561

Chapter 561: A Different Kind of Power

But who would’ve thought he’d see that part of his design in action today?

Because of a development no one had predicted, the battle took a sharp turn.

Marshal Julian’s grip on Luca’s mecha arm tightened, just as a sharp hiss sounded. A split second later, the white mecha’s left arm detached entirely, breaking free with a jolt as Luca drove a puncturing tool directly into the severed forearm.

Fluid erupted in a sudden spray.

"!!!"

"What the—" 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

The crowd reeled, stunned into silence before noise returned in a rush.

Duke Leander jolted up with a strangled sob, horrified at the sight of his son’s mecha losing an arm. His trembling hands clutched at the railing as he swayed in shock.

But then—

"No. Look, our son... He actually detached it himself," Duchess Amelia said in a similarly surprised fashion, eyes narrowing. "Look closer."

And she was right.

The fluid hadn’t come from internal damage. It burst outward in a deliberate arc, spraying across the Marshal’s mecha like it had been made to do just that.

Luca had shielded himself just in time and leapt backward with startling control, keeping the mecha steady despite the loss of a limb.

Julian moved to follow—only to halt mid-step.

His brows furrowed.

Something resisted.

A quick systems check revealed the cause.

Ice. And it was spreading fast.

It coiled up from the legs of his mecha in delicate, crystalline patterns.

Too late, he realized why Luca had shielded himself during the detachment: the fluid had been cryogenic.

The entire move wasn’t exactly planned. But it was one that Luca thought he could pull off. And maybe it’d be a way for mechanics to deal with situations where the power gap was just impossible to bridge. Maybe they could do something in the same fashion.

Because, honestly, there were really times when it was much better to just bolt.

Like now.

So while the Marshal stood frozen in every sense of the word, Luca disappeared once again, slipping into stealth mode.

This time, he didn’t retreat in the direction everyone expected. The fading image of his mecha had been a ruse. The real Luca had already veered the opposite way.

Inside the cockpit, his hands trembled from the adrenaline. His breath came in short bursts, and for a moment, he could hear nothing but the hammering of his own heartbeat.

Then, a grin tugged at his lips.

"Wow," he exhaled. "I’ve never fought like that before."

He sounded stunned by himself, but undeniably thrilled. Somehow, he was still standing.

After gaining enough distance, Luca pulled up his interface, fingers steadying as he accessed the mecha’s space button, from where a replacement arm emerged. Using his internal stabilizers, he guided the component into position. Sparks flew as the mechanized arms handled the attachment process. Cables slotted in. Servos hummed. The limb flexed, fully operational within seconds

And just like that, the mecha was back to normal. Or as normal as a mecha that originally looked part machine, part myth could look like.

Back in the arena, the crowd could barely comprehend what they’d witnessed.

Many clutched their hearts, while others stood frozen, unsure whether to cheer, cry, or collapse.

But among them, one prince sat calmly in the middle of the chaos.

Xavier’s expression remained serene, but his lips twitched slightly as he suppressed a smile. He could imagine exactly how his little wife must’ve felt in that moment—clever, excited, probably still high on instinct and panic.

Perhaps next time, he ought to ask his uncle for more "mock battles" like this.

Around him, the spectators were reacting in waves of disbelief, awe, and reluctant respect. Some wept. Some applauded. While others still looked baffled and confused.

Meanwhile, a certain blonde had nearly scaled his boyfriend’s shoulders in full-body panic.

"MY BROTHER’S MECHA ISN’T EVEN MEANT FOR COMBAT!" Ollie cried out, equal parts proud and appalled as he was completely taken by the scene that just unfolded.

Kyle reached up, tugged him down from his perch, and held him in place as the arena echoed with one final announcement.

"See? It’s the end of testing."

Ollie froze. He actually forgot it was a test.

One that definitely had an ending.

Then, upon processing the announcement, he immediately launched himself into the air again, throwing both hands up in joy.

"I knew it! I’ve always believed in my brother! If anyone could escape that, it would be him!"

Sure, that was one way to put it.

Blergh!

But not that important.
