I Became a Swordsman in the Middle Ages.

"So this is the true nature of Sisilia, the Sword Maiden of the Windsor Knights."

Dessen spoke in a bleak tone.

Just now, he realized how feeble his strength was.

He knew that a knight with an alias was on a different level than an ordinary knight.  

But this...

"...Liharton. Did you see it? Sisilia's sword strike."

"As if anyone could see that."

"Betty, you?"

Beatrice, who was just happy to get out of this annoying dungeon, was startled.

"Something passed by, but..."

"How do you even perceive that…"

Dessen smirked.  

He felt so foolish.

Actually, he thought entering the Windsor Knights was a sure thing.

No, honestly, he thought he was on par in terms of pure skill.  

But that thought changed after seeing Sisilia's sword strike once.

"Forget seeing it, I didn't even perceive it until the demon's head was cut off."

"Why are you getting discouraged now?"

Liharton said while sheathing his sword.

"The Windsor we're aiming for is that kind of group."

"Does that mean there are at least 7 knights stronger than her?"

"Yeah. Don't let that break your spirit so easily."

"Break what spirit. But... it's indeed bleak. I didn't expect the gap to be that big."

Beatrice found Dessen a bit ridiculous.  

'...You didn't know that until now?'

Dessen looked at Liharton and Beatrice with a hardened face and spoke.

"Let's get stronger."

"Of course."

Eyes turned to Beatrice who didn't answer. She clenched her fist in embarrassment.  

"Fi-fight on."

"It's infinite training from today. Don't think of falling behind, and keep up well."

"That's my line, Dessen."

"Betty, don't be too complacent just because you're ranked 1st."

'I... don't want to, though.'

Then, one of the trainee knights looked around and said,

"By the way, why isn't the dungeon ending?"

Even the headless body of the demon still remained.  

Sisilia was also nowhere to be seen after cutting off the head.

"Strange. The dungeon should clear when the demon dies."

"Could there be another condition?"

Beatrice shrugged. She had a bad feeling.

"Everyone, let's go outside for now..."

Kikikiki!

The ghosts they thought were dead surged in like a tide.  

10 times more than before.

**

Mobs in these 'special dungeons' give more experience points than average.  

But it's useless as a hunting ground. Fundamentally, a 'dungeon' was a space with the debuff called rules hanging all over it.

But if there are no rules and mob generation is good?

A very, very excellent hunting ground.

And recommending hunting grounds was a virtue of experts.

"If there was a room like this, you should have told me earlier."

Sisilia was munching on potato chips, a rare sight in medieval times, while looking at a crystal.  

More precisely, at the trainee knights fighting hard inside that crystal.

"I-I'm sorry! It was a privilege that should have been provided immediately when Sisilia arrived...!"

A lone head not far away.

Ricart was sweating profusely and speaking.

'I was worried since I cut off his head, but thankfully he's alive.'

Sisilia wasn't one to miss such a good opportunity.  

She gently admonished Ricart and gave him two orders.

Send lots of ghosts, and tell the ghosts to only attack enough not to kill them.

Thankfully, Ricart was an obedient demon.

'They're fighting well.'

Seeing the striving trainee knights pleased Sisillia.  

She had been keeping an eye on Liharton and Dessen's performances, which were amazing enough to admire.

The newbie Beatrice, whom she favored the most, was especially surprising.

'She was a buffer.'

Beatrice's holy blessing was directed at the trainee knights, not the ghosts.

Buffing is a rare talent. Even within the Windsor Knights, only Lude and Hiter could fulfill that role.

Beatrice's value rose even more inside Sisilia.

She watched without noticing the passing time.

Like that, how much time passed.

Around when the potato chips ran out.

"Hmm... I guess this is enough."

Sisilia yawned and wiped her tears.

The swords of the trainee knights had clearly slowed down.  

Beatrice was even half-crying while fighting.

"The kids are at their limit too. Seems like you're also running out of stored ghosts soon."

She got up from the fluffy chair, drew her sword, and approached Ricart's head.  

Ricart, who had been still as a mouse, spoke desperately.

"I have something to tell you!"

"Hmm?"

"I noticed there was a spy! There's a spy inside the Windsor Knights!"

"I see."

"I-if you spare me, I'll tell you everything!"

Sisilia shook her head.

"No thanks."

"Ah, I'll tell you! I will definitely tell you! I, Ricart, swear my loyalty!"

"No, it's really okay."

"Th-that person will cause big trouble later! If you find out now..."

Sisilia rubbed her eyes and said,

"But it's no fun if I know in advance."

"...!"

"Farewell. The dungeon concept itself was fun. It's a shame the latter part dragged on a bit."

"Please spare me!"

Ricart cried out desperately.  

"I-if you just spare me, I'll do anything!"

Sisilia felt bad.

But...

"You're a virus that pretends to be weak and kills growing newbies. I can't forgive you."

Sisilia hated two-faced people.

***

'It's impossible now.'

Beatrice couldn't put strength in her sword-wielding hand anymore.  

Now, she couldn't even do a single swing.

She had used up all her remaining holy power to the limit, so she had no mana left at all.

If one fell into an endless hell, would it feel like this?  

Kill them and more spawn, kill them and more...

The ghosts truly endlessly swarmed in. Amidst this, it was surprising there were no casualties.

"D-damn it. Betty! Get a hold of yourself!"

"Tell my family back home... I'm sorry."

"I'll tell them, so cast the buffs you were giving us! Otherwise, we'll all die!"

But you guys, isn't this too much...?

Beatrice closed her eyes with a sad heart.  

"Huh?"

"Finally!"

But she opened her eyes again at the cheering voices.  

This annoying mansion was collapsing.

It scattered into the sky as a white powder in the warm wind.

Before they knew it, the trainee knights were sitting in the forest before entering this mansion.  

The dungeon had cleared.

"Woohoo!"

"It's finally over!"

The trainee knights shouted in joy.

Some were already crying and praying to the goddess.  

Beatrice recalled that one of them was a stubborn atheist.

"Good work, everyone."

Sisilia walked over with a soft voice.

She bowed her head.

"I'll end the training here."

Beatrice, who had been tense even after the mansion disappeared, finally let out a sigh of relief.

'It's over...'

Calming her rough breathing, a thought came to her. Could it be that she threatened the demon to move the ghosts?  

…No way, she wouldn't go that far.

'This time I really almost died. I should properly express my gratitude later.'

Right now, she didn't even have the strength to move a finger. Beatrice took a nap-like rest.

Perhaps because the tension loosened? A question Beatrice had put aside briefly during the battle floated up.

-What demons fear most is the Demon King.

At that time, she was too nervous and could only think about giving the next answer...

-If I say I'll tell the Demon King, he has no choice but to be afraid.  

As far as she knew, no human had seen the Demon King and lived, so why was the demon afraid?

Could it be that she had faced the Demon King before...

"Beatrice."

Beatrice, who was looking at the ground, raised her head.

Sisilia was standing there with an expressionless face.

As if she was looking at Beatrice's thoughts.

"I'll be expecting a lot from now on."

It sounded like a warning to Beatrice.

'I-I'll definitely quit.'

She made a firm resolution.  

***

The capital they returned to after a long time was still peaceful.  

The sacred flame was shaking a bit but still safely supporting Theresia.

"It seems the mission ended well."

She sought out Edward first. She had to report this mission.

"Yes."

"Any special matters?"

"None."

Edward asked with a barely suppressed grimace and a smiling face.

"Isn't that amazing? This is the first time there were no casualties in that dungeon."

"...Is that so?"

"It's not a difficult dungeon, but it's structured so that at least a few people die whenever you enter."

Edward said in a low voice.

"You intervened, Sisilia."

"..."

"I told you. The purpose of this mission was to train the trainee knights. Even if there were casualties, you should have made them grow definitively. Even you can't overlook this."

Contrary to his words, Edward looked somehow pleased.

Sisilia's eyes shone.

"Disciplinary action..."

"Everyone improved a lot."

"...What?"

"They probably went up about 13 levels."

"Levels? Ah, the growth level you mentioned."

Sisilia had the eyes of wanting praise. If she were a puppy, she would have wagged her tail.  

She believed without a doubt.

As a result of this mission, her favorability would have increased.  

Not only were there no casualties, the knights' skills developed significantly.

Even in her own thoughts, it was a perfect mission completion.  

"I don't know the exact reference point for levels, but 13 levels. That's quite a big number."

"They improved anywhere from 20% to 45%."

"You achieved such results without casualties?"

"Yes."

Sisilia smiled slightly.

She disliked missions, but it was always good to be praised when they ended well.

"Amazing. To the point it's unbelievable."

Seeing Edward's doubtful face, it seemed he couldn't believe it.

The instructor, Marcus, would verify its authenticity.  

Before that, there was an urgent issue to discuss.

"Excuse me, Vice-Captain."

"...Speak."

"I spent some funds for this mission. I believe the headquarters should pay for the amount used for the mission."

Edward nodded with a slightly irritated expression.

"That's natural. It's money used in the mission. Organize the related matters and submit a report..."

Of course, the perfect Sisilia had already swiftly submitted the report.  

She held out the scroll to Edward.

Edward received it blinking.

"About 1300 gold. (TN: Approximately 1.3 billion won; Source: Author)

For reference, Edward's annual budget was about 1000 gold.

Edward blankly stared at Sisilia.

Sisilia was already standing by the door, bowing her head.

"Farewell."

That day, a rumor circulated inside the Windsor Knights about a scream heard from Edward's office.
