[WN] Jitsuwa 3-Domedatta : Chapter 104


Chapter 104

(Kyle Calendar Year 507: Age 14)

Formation of the Frontier Knights ② - Secret Weapon

"Prepare for annihilation volley! Target 800 m ahead! Adjust firing angle!"

 

"Adjustment complete!"

 

"Mages are ready!"

"Blue flag is up! Observers have evacuated the target zone!"

 

Receiving the reports, I prepared to give the command.

 

"Ready... Fire!"

 

A single gigantic catapult launched an unimaginable quantity of metal spheres. The massive number of metal spheres, fired with incredible force, spread out as they flew and landed in the target area, marked by the observers' flag, raising a cloud of dust.

 

Their destructive power was tremendous, leveling trees across the target area and gouging the earth. From a distance, one could see trees being blown away over a wide area, ascending into the air, indicating the sheer power. A moment later, the sound of their impact reverberated as a roar. By then, the entire area was enveloped in a cloud of dust, obscuring everything.

 

"Th-this is..."

"Good heavens..."

 

The two who had come to observe the live firing of the newly completed catapult were speechless at its immense power.

 

This was the planned construction site for the Demon Realm fortress, which I had visited previously with Elan. Construction had just begun, with only a portion of the fort's walls, which would serve as its base, recently completed. I was showing them the live firing of the catapult, a new development for anti-monster and anti-invasion measures, which had been preemptively installed on the fort walls.

 

"Of course, this range and power are the result of the fusion of mechanical force and Mage skill. Understand that without magic, this range and power would be halved."

 

"Nevertheless, it's amazing. The enemy army wouldn't stand a chance against this."

 

"Precisely. If the enemy is hit by an area attack at this range, they'll be defenseless. This is something truly terrifying."

 

Margrave Hastburg and Viscount Gorman finally voiced their impressions.

 

Actually, there's something I haven't told them. It's true that the acceleration and targeting of the metal spheres are largely dependent on the Wind Mages' magic and their skill. However, the performance of another Mage is the most crucial point in this firing. Yoltia, a Gravity Mage, a type of Mage rare even in Kyle Kingdom, almost non-existent in fact, secretly uses weight reduction magic on all metal spheres at the moment of launch. Because of this, the catapult does not damage its arm from the weight load of the projectile, can carry a weight beyond its original capacity, and the installed counterweights are able to fully transfer the recoil of that weight. The metal spheres launched into the sky regain their original weight once they gain initial velocity and then continue their flight.

 

The metal spheres themselves are recycled. I had a large quantity of discarded weapons and other scrap metal, captured during the Teigun defense battle. For the time being, anything that cannot (or will not) be used as raw material will be melted down and repurposed into these metal spheres.

 

 

The path to this point was not easy.

 

Firstly, we prepared to independently produce and improve the siege weapons in this world with the help of craftsmen, led by Foreman Karl.

 

Secondly, we relentlessly continued experiments and training with the Gravity Mage (Yoltia), the Wind Mages, and the archers responsible for the firing. Initially, coordinating the timing of the three was quite difficult, but recently, we finally managed to launch them as intended.

 

At the moment of projection, a gust of wind generated by Wind Magic—a pinpoint, but stronger than any typhoon's tailwind—accelerates the projectile, which regains its original weight at the moment it gains initial velocity. If these stages synchronize perfectly, even in this world without gunpowder, it can achieve power comparable to artillery.

 

Then, like a howitzer, the iron spheres arc through the sky, raining down on the target area like hail. No, perhaps it's more accurate to say the metal spheres heavily impale the ground, given their low trajectory.

 

In this world without cannons, a long-range, wide-area annihilation attack with unimaginable power, something usually inconceivable, is what I envision as our trump card for the future. I named this weapon, capable of achieving devastating results equivalent to dozens of cannon shots with a single launch, the "Magic Cannon," and will be our secret weapon from now on. It's only a single character difference, but I was excited by the naming. Just changing "Ma" to "Ha" makes it sound like some incredible ultimate weapon. Or perhaps I should have added "Dispersal" to it?

 

 

"Is this, a part of the countermeasures he spoke of, to repel armies of tens of thousands...?" Viscount Gorman murmured, half in a daze.

 

"Yes, the next time the Empire invades, they will likely come with at least 50,000, perhaps even more. The First Imperial Prince, burning for revenge, and the Third Imperial Prince, seeking to assert his superiority, will both target this route, having made thorough preparations. That is my reading."

 

"That's a prediction I hope doesn't come true..." The Margrave's expression was grim.

 

If the Southern Gate Fort, which would be the main battlefield, were to face an invasion with even greater forces than before, it would naturally be impossible to defend.

 

"We likely have a few years to five years to spare. The Empire is currently in a delicate state. However, once the Empire's southern front is settled or the imperial succession is determined, the situation beyond that will be unpredictable."

 

"I will propose to His Majesty the construction of a new fortress in the Southern Gate area. At that time, I will also seek his approval for this fortress here. After all, the fortress and defensive line you are planning will certainly not be achievable with merely 50,000 gold coins."

 

"Thank you. I believe that if we can prepare to take on more of the enemy forces here to reduce the burden on the frontlines, it would be beneficial."

 

"If we proceed along those lines, the proposal might be more easily accepted," Viscount Gorman agreed.

 

"So, the day we can sleep soundly with high pillows is still far off, huh?"

 

"That's right."

 

"I have one more request for you both. This weapon, the combined magic and projectile firing, I've shown it only to you two. From now on, even my own father will only see regular firing. On that point, I humbly ask that you keep it absolutely secret from other nobles as well."

 

"Of course. We shall repay your trust with our own."

 

"Indeed. Rather, I am grateful to you for revealing it even to me, from a neighboring territory."

 

"Feel free to utilize the Knights to their full extent in the construction. Since I, the commander of the Frontier Knights, have instructed it, it should be logical."

 

"I will also thoroughly instruct the soldiers I entrust to you."

 

I received the tacit approval from the dignitaries, which had been a pending matter, in the best possible way. Commander Weiss also nodded profoundly beside me.

 

 

And... there are still a few hidden trump cards I haven't told the two of them about.

 

First, the development of these hidden trump cards involved several stages.

 

The first was to research combining different types of magic to drastically enhance their effects.

 

The second was to explore enhancing the effects of combined magic using pre-prepared materials. For example, using oil with fire magic.

 

The third was, similar to the Magic Cannon this time, to fuse tools (weapons) with magic to maximize their effects. In fact, several weapons have completed prototypes and are in the experimental stage.

 

To maintain secrecy, attack methods other than the newly developed Magic Cannon are still hidden. Only the Mages involved in their use and a minimal number of soldiers who participated in training and test operations know about them. Furthermore, the Magic Cannon itself is still in the experimental stage, but I intend to refine it into an even more devastating weapon.

 

The development and deployment of these will proceed in parallel with the fort's construction and are intended to become core defensive facilities once the fortress is complete.

 

Additionally, I constantly discussed and formulated plans with the Commander for effective (and brutal) operations when facing large armies.

 

"Even so, these... I truly think it's good I'm not an Imperial soldier." The Commander sighed heavily when I told him my plans.

 

"It may seem cruel, but the goal is to break the enemy's fighting spirit with the first strike and make them abandon their invasion. Frankly, I don't believe these alone can overturn a numerical disadvantage and lead to victory. The point is to be able to fight a battle we can't lose, that's what I think."

 

Indeed, no matter how strong a fortress is built, facing tens of thousands of enemy soldiers with significantly fewer defenders is a severe disadvantage. The enemy will likely target weaker points within the vast defensive lines and breach them.

 

Therefore, the objective should be to create a situation where, even if we can't win, the enemy is terrified and forced into a stalemate. If so, the presence of the Demon Realm itself will naturally function as a defensive network (monsters will become active).

 

Thus, the construction of the Demon Realm fort was put on track and will continue to be promoted.
