Yuki stood silently with a sad expression while Tiyara looked at him with concern.
"Yeah..." Yuki said quietly.
"It's something like that."
But inside his mind, another thought echoed.
Well... it's a lie.
I can't exactly tell her that I'm from another world.
Tiyara's expression slowly turned serious.
"I understand," she said softly.
"My parents were also killed by the Demon King's army during a war a few years ago."
"So... I understand how you feel."
Hearing that, Yuki looked slightly surprised.
"I didn't know that..."
Tiyara gave a small smile.
"It's okay. I never told you."
"Anyway... what are we going to do about Jelrai now?"
Yuki fell into thought.
Hm...
Then suddenly, he looked toward Tiyara.
"What if we create a weapon that can throw flames without using mana?"
Tiyara blinked in confusion.
"That's... impossible, isn't it?"
"How can a weapon create fire without mana?"
Yuki thought silently.
Well... if I compare it to Naco Country's technology, their weapons were already highly advanced.
And Precious also created incredibly powerful weapons before.
So what if... something similar could launch flames instead?
Yuki looked at Tiyara seriously.
"I have a plan."
"But I'll need a few materials."
Tiyara tilted her head.
"What materials?"
Yuki answered seriously.
"First, I need iron."
"Second, oil."
"And third... gunpowder."
Tiyara looked even more confused.
"That's it?"
"What kind of weapon can you even make from those three things?"
Yuki began explaining with hand gestures.
"I need to shape the iron into an 'L' form."
"Then we'll add several materials inside it."
Inside his mind, however, Yuki felt uncertain.
I never actually saw that weapon properly in my previous world.
I only heard about it.
So I don't really know how it's supposed to be made...
Still, Yuki suddenly walked closer to Tiyara and placed a hand on her shoulder confidently.
"I trust you."
"You can make it."
"After all... you're the Master of the Tower of Knowledge."
The moment he said that—
Tiyara's cheeks instantly turned red.
"O-Okay...!"
"I'll try my best...!!"
Yuki smiled slightly.
Then Tiyara returned to her normal tone.
"But I'll need time."
"I'll research it together with the tower members."
"And gathering the materials alone will also take some time."
Yuki paused briefly.
"I see..."
"How much time do you need?"
Tiyara walked toward the door before answering.
"The more time we get, the better."
Yuki nodded calmly.
"Hm... got it."
Then Tiyara left the room.
Yuki's narration continued.
After that, Tiyara began researching together with the tower members for many days.
Meanwhile, I started clearing the tower floors.
Several scenes flashed by—
Yuki cutting down goblins with his sword.
Traveling alone through deep forests.
Fighting and killing a giant bull-like demon.
Days passed one after another.
Eight days later—
Inside the library—
Yuki and Tiyara stood beside a table.
Resting on top of it were two large pistol-like weapons.
One was colored white and yellow.
The other was white and red.
Tiyara spoke proudly.
"So... after a lot of research, we finally made this weapon."
She picked up the red-and-white pistol and handed it to Yuki.
"To create this, we had to carefully read every related book two or three times."
"And more than three hundred people worked together to build it."
Yuki accepted the weapon carefully.
"So... this thing can really throw flames?"
Tiyara nodded.
"Yes."
"It's the trial model we created."
"Its range is around one or two meters."
Then she picked up the yellow-and-white version proudly.
"And this is the final model."
"Its range is around seven to ten meters."
"And the flames are much stronger."
Tiyara stared proudly at the weapon before suddenly becoming energetic again.
Then she excitedly grabbed Yuki's hand.
"Do you want to try it?!"
"Hm? Hm?!"
Without waiting for his answer, she immediately dragged him outside the library.
"Then let's go test it!!"
Twelve days earlier—
The battlefield after the war.
Noon.
A liquid-like man stood silently among countless dead humans and demons.
Blood covered the battlefield.
The mysterious figure quietly observed the corpses with sharp eyes.
Then, in a cold and serious voice, he muttered—
"As I thought..."
"You are dangerous for milord."
Present time—
Yuki finished inspecting both weapons carefully.
Then he casually asked—
"What's the name of this weapon?"
Tiyara answered innocently in her usual cheerful tone.
"We didn't give it a name."
"It was your idea, so you should name it."
Yuki looked at the weapon quietly for a moment.
Then he answered—
"Then its name is..."
"Flamethrower."
