Only I Know the War Hero's Secret [Novel] Chapter 27 – A Deduction in the Dark

Translator: Nox

October 13, Imperial Year 664.

An unprecedented outbreak of spore-type monsters swept across the western forest.

It was entirely thanks to a monster that Mona had begun suspecting the second Imperial classified report might contain an error.

The previous night.

Following the trail of blood left by the serpent, Mona’s party had ventured deep into the dark cavern.

Tracking the beast offered the chance of discovering a safe, swift shortcut into the demonic realm.

The path the Twin Head Drake had carved out was narrow and winding, but its structure was straightforward, free of branching tunnels.

After a considerable hike, they found the exit the serpent had used.

Rihart Cronel
“It escaped through the ceiling.”
Dominic
“A snake might slither up that, but no human could climb it.”

Dominic clicked his tongue as he peered up at the ceiling, pierced almost vertically above them.

Mona Bellose
“…Something isn’t right.”

Mona muttered under her breath, gazing up at the faint moonlight pouring down through the round shaft.

Rihart Cronel
“What do you find odd?”
Mona Bellose
“According to the map, that opening leads right near the forest where the spore monsters supposedly broke out.”
Rihart Cronel
“…And?”
Mona Bellose
“Records show that monsters avoid drawing near rampaging specimens. Demonic energy in a state of chaos poses a threat even to other monsters.”

Pushing up her thick spectacles, she continued.

Mona Bellose
“The Twin Head Drake was in a vulnerable state from crafting a water jade. It defies common sense that it would willingly head back toward danger.”

“…”

Mona Bellose
“My impression is that the spore monsters never rampaged at all.”
Rihart Cronel
“Are you suggesting the Imperial classified report is incorrect?”
Mona Bellose
“Yes. For spore-types, the reported area of the outbreak is far too vast, as well…. Something feels off. Cough!”

No sooner had Mona finished speaking than her whole body hitched with a fit of coughing.

Keeping pace with knights of extraordinary stamina had evidently taken its toll, leaving her voice raw, hoarse, and strained.

“…”

As Rihart quietly studied her, Dominic walked over from scouting the area.

Dominic
“Commander, it might work for knights, but hauling an entire investigation team up a rough passage like that is out of the question. Moving overland would be much easier.”
Rihart Cronel
“Understood. We head back.”
Dominic
“Yes, Commander.”

Having ordered the retreat, Rihart glanced up at the hole where the serpent had vanished and abruptly halted in his tracks.

Rihart Cronel
“…Dominic.”
Dominic
“Sir?”
Rihart Cronel
“Take Mona Bellose and return to the lodgings first. I will inspect the area further.”

His voice sank to a low murmur as he added:

Rihart Cronel
“The moment you arrive in the fief, notify the alchemists that the water source might be contaminated by monster blood.”

Entrusting Mona’s escort and the dispatch to Dominic, Rihart drew a stiletto from his coat and a folding knife from his pocket.

To scale that vertical shaft, a pocketknife and a single dagger were more than enough for him.

Reaching upward with his right arm, Rihart leapt as high as he could.

Crack!

Coated in mana, the stiletto bit into the rock wall as effortlessly as slicing through cake.

Next, he extended his left arm, driving the folding knife into the stone.

Alternating between the two blades glowing with pure white mana in each hand, Rihart pulled his upper body upward.

Water trickled down the damp rock face, drenching his shirt in moments, but he paid it no heed.

Ascending rapidly through the narrow shaft the serpent had taken, he hauled his body cleanly out through the opening.

In an instant, the clammy, suffocating air of the cavern vanished, replaced by a gentle breeze brushing across his face.

“…”

During his climb, the blue light of dawn had settled over the woods. Rihart took in the surrounding landscape with a measured gaze.

The forest before his eyes was entirely peaceful.

Leaves stirred lightly on the wind, and in the distance came only the soft murmur of running water.

Just in case, Rihart extended his senses to their sharpest peak, scanning the surroundings.

Yet nowhere was there any trace of the chaotic demonic energy that a berserk black dragon or monstrous bird would unleash.

‘My impression is that the spore monsters never rampaged at all.’

Her intuition had been spot on.

“Ha…”

A brief scoff escaped Rihart’s lips.

Why had the Imperial classified report contained faulty intelligence?

A mere mistake?

To brush it off as an administrative oversight sat ill with his instincts.

The Imperial court was a tangled web of countless conflicting interests.

Once the expedition into the demonic realm concluded, he would have to thoroughly grill the officials who drafted the classified documents.

Mona Bellose
“…In short, it was thanks to the monster that we realized the western forest is untouched.”

Encircled by members of the investigation team, Mona gave a brief account of the previous night’s events.

The moment she finished, questions began flying at her from all sides.

“So you deduced it was safe because a monster in a weakened state chose that direction to hide?”
Mona Bellose
“Yes.”
“Do you have any other supporting evidence?”
Mona Bellose
“…Well, in the case of spore-type monsters, it is difficult for them to spread across an area as vast as marked on the map.”
“Why is that?”
Mona Bellose
“As spore monsters diffuse, their potency dilutes. If the concentration of airborne demonic energy drops below the critical threshold, germination falters.”

Unaccustomed to having everyone hang on her words regarding monster ecology, Mona steadied her fluttering breath before continuing.

Mona Bellose
“This is not the heart of the demonic realm, but the outer fringes. Spore monsters have strict limits on how far they can expand here.”

When she concluded her explanation, a murmur rippled through the gathered crowd.

To personally accompany a monster subjugation and expose a blunder in an Imperial report—

The bold conduct of a monster scholar who had seemed so timid and quiet left the investigators thoroughly astonished.

Even more shocking was that Rihart, an untouchable hero, had trusted this unknown scholar’s word enough to scout the sealed territory himself.

Seeing the Bellose daughter win the confidence of a commander known for his icy detachment, some swallowed back jealousy and envy.

And for others, it became the moment the name Mona Bellose was etched firmly into their minds.

***

Once the commotion settled, Rihart issued new instructions.

Rihart Cronel
“We cannot sit idle for three weeks waiting on a purifying priest.”

His eyes swept across the investigators.

Rihart Cronel
“This clearing is no longer viable as a base camp. We will advance to the northern boundary to scout a new campsite.”

Inwardly, Rihart considered this turn of events a blessing in disguise.

From the start, he had never been fond of setting up base camp in an open plot entangled with the local lord’s interests.

‘An empty patch of ground is far preferable to dealing with freeloaders.’

Moreover, shifting to the upper boundary allowed a direct straight-line advance toward the peak of Mount Kirki rather than a diagonal route, drastically cutting the travel distance.

Not only would it compress the expedition schedule, but it also reduced the number of footholds required inside the demonic realm.

Taking the shortest possible route was advantageous in every conceivable way.

Following Rihart’s decision, the investigation team packed their gear once more to seek out a new campsite.

Mona Bellose
“…Assign me to the vanguard?”

Mona’s eyes flew wide as she furtively slipped peanuts into the slime’s pouch.

Natasha Rohmeyer
“Yes. I heard Lady Mona made a tremendous contribution, and that you bravely accompanied the subjugation.”
Mona Bellose ///
“Ah, no, that isn’t…”

She had only followed along because she was far more worried about the monster than the humans. Confessing that outright would get her branded a witch.

Natasha Rohmeyer
“You are modest.”

“…”

Natasha Rohmeyer
“Commander Rihart holds your recent deed in high regard. It appears he appointed Lady Mona to the vanguard and assigned me to escort you.”
Mona Bellose
“I-is that so?”
Natasha Rohmeyer
“However, a carriage lacks mobility, so we must travel on horseback.”
Mona Bellose
“Pardon me, but I am not very skilled at riding.”

Most noble ladies learned horsemanship from childhood, but Mona had spent her early years glued to her grandmother’s side studying monsters.

Even after her parents returned from abroad, she had rarely ridden, possessing barely enough skill to manage the basics.

Natasha Rohmeyer
“Then you may ride in front of me.”

Natasha offered the suggestion with utter nonchalance.

‘…Doesn’t she hate physical contact?’

Still, Mona could hardly bring that up to her face, so she merely nodded.

An hour later.

Clop, clop, clop.

‘S-save me…’

Led by Rihart, the elite of the Black Knights took off across the hills at a speed Mona could scarcely endure.

Gripping the saddle with clammy hands and clamping her legs tight, Mona renewed a thoroughly pointless resolution.

She really needed to train her core.

Natasha Rohmeyer
“Is the pace acceptable?”

Natasha asked from behind. Loath to become a burden, Mona forced out a reply.

Mona Bellose
“I-it is fine.”
Natasha Rohmeyer
“Then we will pick up speed.”

On second thought, perhaps being a burden wouldn't have been so bad.
