The Extra Prince Sets Out To Conquer The World

It had been about four days since arriving in Blantzbarg.

“Huff! Huff! Huff!”

I was currently running hard around the training grounds, panting roughly.

This damned body was still weak even after eating such nasty medicine and exercising.

Still, compared to when I first entered this body, my stamina had improved a lot.

Even so, it was only at the level of an ordinary girl my age.

Honestly, the medicine smelled and tasted too much like a sewage treatment plant, so I couldn’t eat it often, but still, if I ate that much, shouldn’t I at least become a healthy young man?

“Ahahaha! Hang in there!”

“But are you really a royal knight like Sir Gilbert?”

“Being this weak, you won’t survive even a day in the Bastille Mountains.”

The soldiers of Blantzbarg leisurely did physical training and overtook me.

I don’t know how many laps I had been overtaken.

“Hah, ahem! Young master. Isn’t this too much strain?”

Gilbert still made the mistake of addressing me and ran beside me, sweating.

The speed Gilbert and I ran at was similar, but the difference was that I was just running, while Gilbert was running with a gravity-increasing magic tool, with nearly three times the weight.

“Huff! Huff! Don’t talk!”

I tried to say it was fine, but I was too exhausted to want to speak long.

“…I’m sorry.”

Gilbert shut his mouth, looking down as if he thought I was angry.

No, if you react like that, it makes me feel bad.

After running hard for a while, when I reached my target, I lay down on the ground as if collapsing.

As I panted, Precia, who had finished her physical training matching mine, handed me a towel.

“Your stamina has improved a lot.”

Precia, who knew my original stamina, complimented me.

“Hah! Hah!”

Instead of saying thanks, I exhaled roughly and nodded, grabbing the towel with trembling hands and wiping my face.

It’s freaking tiring.

Then, Zillian No. 79 set up a recovery magic circle next to me and lifted me up to move me.

“Vice-Master’s bio-signals are unstable. Danger level 3 rating, implementing emergency treatment.”

Actually, level 3 meant it wasn’t particularly dangerous.

According to Geor’s rating system, level 1 was a serious injury leading to death, level 2 was a serious injury not life-threatening, and level 3 was a simple minor injury.

Zillian No. 79 placed me on the magic circle and infused magic power.

As the magic activated, breathing became easier, and the fatigue gradually subsided.

“Phew~! I’ll live. Zillian No. 79, where is Sillua?”

“Searching the archive for the answer to Vice-Master’s question ‘Where is Sillua?’. …Master is currently 198 degrees southwest, 541 meters away from Vice-Master’s location. That concludes the answer.”

“Southwest… Ah, she must have gone to the doll storage already.”

The doll storage was the place where the combat doll battalion Geor left behind for Blantzbarg territory was kept.

Although I did tell Demiway that I would repair the dolls to put him in my debt, perhaps because they hadn’t been properly maintained for the past 20 years, not a single doll was left intact.

The total number of dolls was around 6,000, which was a lot, but as they were a supply model Geor made 30 years ago, the structure wasn’t difficult, and Sillua’s mansion had maintenance facilities, so repairs were sufficiently possible.

Since I told Demiway I would repair them, I was going to repair them alone if he lent me the facilities and the Zillian series to assist me.

However, Sillua seemed displeased that Geor’s dolls were left in a broken state, so she began fixing the dolls herself.

“Ugh! I should go help too.”

As I got up, a noisy sound was heard from far away.

Clang clang clang clang-!

The sound of a bell ringing to alert an enemy attack rang out noisily from the castle walls of the Bastille Mountains.

“Hans Centurion unit! 5 minutes! Arm and assemble!”

“James Centurion unit! Arm and assemble!”

“Girn Centurion unit! Arm and assemble!”

The soldiers doing physical training at the training grounds swiftly ran to their respective barracks as if familiar with it.

It was the first commotion I had seen since coming here.

“Precia, Gilbert. Take care of it and come back.”

At my order, Gilbert hesitated.

“But we are…”

I knew what Gilbert wanted to say. As my escorts, he must be reluctant to be far from me.

“Why? Should I go too?”

At my playful question, Gilbert shook his head in shock.

“No! It’s fine!”

Judging from Gilbert’s expression, he seemed to have imagined me in the midst of training against the dolls.

“I’ll be where Sillua is from now on, so if you’re worried about me, finish quickly and come back. We have to earn our keep from the Blantzbarg commander, right?”

At my words, Precia nodded with a smile as if it couldn’t be helped.

“We’ll take care of it and come back quickly.”

“Remember, safety first.”

I waved my hand as if seeing off Precia and Gilbert running towards the castle walls.

“Navi. Protect the kids if they make a mistake.”

Precia would be fine even if she made a mistake, but not Gilbert.

-Nyaong~!

Navi leaped from my shoulder and disappeared like the wind.

The sensation connected by the contract informed me that Navi had perched on Gilbert’s shoulder.

“Zillian No. 79, let’s go fix the dolls.”

“Yes, Vice-Master.”

I took Zillian No. 79 and headed to the doll storage.

Precia and Gilbert, who ran to the castle walls, climbed up the walls in one go and assessed the situation.

“Lizardmen, about 1,200 in number?”

Gilbert counted the number of approaching monsters by eye.

Although they didn’t swarm in all at once, blocked by traps and barricades set up in between, the sheer number was still threatening.

“As expected of the notorious Bastille Mountains. So what do we do?”

At Gilbert’s question, Precia couldn’t answer hastily.

Precia was only 15 years old.

Even she tensed up at the horde of monsters in numbers she was seeing for the first time.

She could tell that each individual monster was worthless, but she had learned that war couldn’t be determined by individual fighting prowess.

As Precia hesitated, Yuan’s voice was heard from the butterfly perched on Gilbert’s shoulder.

-What are you dilly-dallying for? The barricades are arranged in a grid to naturally disperse the monsters, so it’s obvious you just need to take care of the ones coming through the chokepoints.

As the structure of the castle walls was in an angular star shape, there was little worry of being caught from behind and ambushed near the castle gate.

Hearing Yuan’s words, Precia made a decision and shouted to the commander leading the arrow-shooting soldiers.

“We’ll strike down the monsters approaching the castle gate! Please attack the monsters coming from afar first!”

“…What?”

The commander made a dumbfounded expression seeing the youthful-faced Precia.

But Precia jumped down the castle walls without minding him.

“Follow me! Gilbert!”

“Huh?!”

Gilbert was surprised to see Precia landing safely below the high castle walls.

-She said to follow.

Yuan’s voice rang in Gilbert’s ear, and a strong wind blew from behind, pushing Gilbert.

“Aaaaah! …Ah?”

-Nyaong!

The wind from below pushed up Gilbert’s body, reducing his falling speed.

Gilbert barely regained his balance and landed below the castle walls.

“Ugh! I, I thought I was going to die!”

It was his first experience falling from the 20-meter-high castle walls.

Navi, seeing Gilbert clutching his chest in surprise, tapped Gilbert’s cheek with its front legs as if slapping him.

Coming to his senses, Gilbert drew his sword and chased after Precia.

Precia had already dealt with the lizardmen that reached the castle gate and stood on the right side of the barricade installed in the center right in front of the gate.

“I’ll take this side, so you take the opposite side.”

As they approached the castle gate, the chokepoints narrowed due to the star-shaped fortress structure.

Even if the chokepoints narrowed and were blocked by barricades, it wasn’t an easy task to block them alone, as it was still a path where armies passed through.

“Yes! Understood!”

However, Gilbert blocked the chokepoint without hesitation.

It was a much better condition than a situation where dolls relentlessly pushed in an open space.

“Grrrr!!”

A lizardman charged at Gilbert with a ferocious growl.

Gilbert dodged the claws swung by the lizardman and swiftly cut its neck.

Before the lizardman’s head even fell to the ground, Gilbert split the heart of the headless lizardman and cut off both arms and legs in succession.

“Gilbert! The opponent isn’t a doll! They die just by cutting the neck or heart!”

“Ah! R-right?”

As Precia cut the necks of three lizardmen with one slash and gave a warning, Gilbert came to his senses.

Geor’s dolls didn’t stop moving just by hitting the neck.

So, the core had to be shattered, and although it was mostly located in the heart, there were cases where the core was in a different place, so he developed the habit of cutting off the limbs.

A month was a short time, but it was enough to instill an almost trauma-like obsession in Gilbert.

“I’ll be careful!”

Wasting stamina unnecessarily on the battlefield was something that shouldn’t be done.

Gilbert cut the necks of two lizardmen charging at him in succession and unconsciously stabbed their hearts.

He stopped the action of trying to cut off the limbs out of habit and cut down the lizardmen charging at him.

And then, as if it was a single motion, he cut off the heart and both arms again at a speed that felt like it.

“Ah! Mistake!”

Before long, lizardmen that were hit by arrows shot by the soldiers on the castle walls and bleeding from various parts of their bodies began to charge.

The wounded and starving monsters were weakened but at the same time became more ferocious.

The attacks of the monsters filled with murderous energy pressured the inexperienced Gilbert’s mind.

The dolls were stronger in terms of strength, but they didn’t pounce with murderous energy to the point of being wretched.

Under pressure, Gilbert cut necks, split hearts, and severed limbs according to his ingrained habits.

And he consumed more stamina.

As Gilbert swung his sword while panting roughly, an overwhelming fighting spirit was emitted from Precia’s direction at that moment.

The monsters left with nothing but instincts due to starvation greatly retreated as if running away.

Some of the already weakened lizardmen fainted, crushed by Precia’s fighting spirit.

“Quickly clear the ones on the ground!”

At Precia’s order, Gilbert realized that lizardmen corpses had piled up at his feet before he knew it.

The reason his movements were uncomfortable wasn’t solely due to the monsters’ murderous energy.

The terrain that restricted the enemy’s movements conversely meant that it also restricted the allies’ movements.

Precia pushed the monsters forward when cutting them down to use them as obstacles to block entry, but Gilbert couldn’t do that.

Gilbert urgently kicked the corpses to make space to move in the gap the lizardmen had retreated.

“Not many left! Endure a bit more!”

At Precia’s shout, Gilbert composed his breathing and straightened his mind.

Although it was difficult to grasp the exact number like on the castle walls, he realized that he had cut down over a hundred in a short time.

Precia’s movements were faster and less wasteful than Gilbert’s, so she killed more than twice as many enemies in the same time.

As he pointed his sword at the monsters again and took a stance, the castle gate behind him opened.

“Hans Centurion unit! To positions!”

“James Centurion unit! To positions!”

“Girn Centurion unit! To positions!”

Three hundred soldiers rushed out from the castle gate, killing the lizardmen and occupying the chokepoints divided by the barricades.

The horde of monsters, which had lost momentum due to being wounded by arrows and reduced in number, began to be massacred by the soldiers.

It was about 15 minutes after the bell rang.

Centurion Hans patted Gilbert’s back, who was panting roughly, and laughed cheerfully.

“Ahahaha! As expected, your skills are superb, guest! Thanks to you, the work became easier.”

“Ah… not at all. I survived, thanks to you.”

Perhaps because he was too nervous, his hands and feet trembled even though he still had stamina left.

It was Gilbert’s second real battle.

“By the way, did you have a grudge against the lizardmen or something?”

Hans gulped, looking at the pile of dismembered lizardmen corpses.

It was a face disgusted by the cruel handiwork that didn’t match his innocent-looking impression.

“N-no!”
