This is the Ultimate Romantic Story for Men

"Ahem, sister, I've had an idea recently. Would you like to work with me to create some interesting magic props?"

Kishi decisively chose to change the subject.

When Agnes heard about the magic props, her eyes lit up, and she became genuinely interested.

"Eh? Magic props designed by Kishi? Okay, great! I'm very interested in them, I want to make them! What kind of props are they?"

"Alright, let's think about it. It's a long-range weapon with great power and a small size. I'm kind of tired of playing with swords lately. Never mind, I'll draw the design for you."

Although this was a change of topic, it was still business.

Kishi hadn't forgotten his plan to switch weapons. Although there was already the strongest weapon like the Deli EA Sword, it was too powerful, consumed too much energy, and was too noisy, making it unsuitable for use as a regular weapon.

He drew the design on a piece of paper. In his previous life, he had read many books on firearms, and Kishi chose the most powerful revolver from those books.

The M500 pistol!

With a 0.50-inch caliber, that is, 12.7 mm, it fired high-powered 0.50-inch Magnum pistol ammunition. The kinetic energy of the bullets it fired was twice that of the famous .50 caliber "Desert Eagle"!

Rather than calling it a pistol, it was better described as a "cannon" in your hand!

[Originally, I could make it myself, but... its power is still too small. I always feel that its firepower is still lacking, and there is room for improvement.]

Kishi remembered all the production details.

Although the level of craftsmanship in this world was much lower than in his previous life, and it was difficult to make the same materials, there were many magical minerals.

For example, Mithril, Orihalcon, Elf Stone, etc., using these as the weapon's body materials could produce stronger power.

He looked forward to it.

Hoping to blend science and magic.

To build the most amazing weapon in history!

"Wow, I always feel this is a very great weapon. Kishi, are you doing this for..."

"Romance! It's for romance!"

Kishi said without hesitation.

Although strengthening his own weapon was one reason, the most important thing was romance... What good is a boy if he doesn't like weapons!

"...Hmm, since it's a matter of romance, we can't do anything about it. I get it, big sister will do her best!"

Agnes nodded in agreement after a moment of silence. This seemingly outrageous reason was fully acknowledged by her.

After all, this unparalleled princess also lived for romance... a girl.

To concentrate on studying magic props, she had directly given up her right to inherit the throne, refused to marry, and publicly declared that she would remain single for the rest of her life.

Although if we had to compare, there's no doubt that Kishi had done even more and greater things. If His Majesty the King knew, he would surely spit out three liters of blood.

But Kishi hid it very well, so he was never scolded.

But Agnes basically didn't hide anything...

Some time ago, to fly in the air, she used a wind fairy stone to blow herself up, and ended up embedded in the city wall.

During etiquette class, the dance teacher found that the man had a forbidden book hidden behind his skirt.

To get research materials, I recently went to the Adventurer's Guild to register as an adventurer and hunted World of Warcraft by myself.

The main cause of stomachaches for His Majesty the King! The source of all evil for all races! The unparalleled princess!

Now the main responsibility of the Royal Knights had changed from guarding the palace to guarding Agnes. It could be said that if she were caught, she would be immediately arrested, then escorted back to the palace and detained for half a day.

"Kishi, are you a genius?"

After a while.

Agnes looked at the drawing in her hand with trembling eyes, her breath heavy, without any princess-like demeanor, and the ahoge on her head stood up.

"An incredible design. It can achieve this level just by relying on mechanisms. It's hundreds of times stronger than bows and arrows!"

But it can still be further enhanced!

Agnes squinted her eyes.

Countless inspirations surged in her mind,

She couldn't wait to try it!!

For example, you could use elf stones with different attributes as bullets, fire attribute bullets, water attribute bullets, thunder attribute bullets, and so on. Just thinking about it was amazing, the elemental reaction could be played with!

The weapon body could also be made of Mithril or Orihalcon, which could withstand stronger bullets and increase durability and continuous firepower.

"Sister seems very excited."

"Of course~ I can't wait to make such a powerful magical object!"

"Really? As long as you like it. By the way, I also have some [opinions] about flying."

While Kishi smiled, he told Agnes about the fragmented knowledge of the concept of elevation and air hydrodynamics from his previous life.

"My Kishi is the best in the world!!!"

Agnes shouted after hearing this.

She opened her arms and hugged Kishi, then jumped up and down excitedly. The girl was now more enthusiastic than ever.

She never thought that her beloved brother would have extraordinary talent in magical objects, and now she felt extremely happy.

It can be done! It can be done!

With Kishi's help, your dream will surely come true. You can definitely become a magician and fly to the sky with your own magical equipment! (see picture)

"Ehm, sister, don't get too excited..."

Kishi was not moved at all, it was just a face cleanser for a little girl, it was too soft, so she had to go back and grow it for a few more years.

Finally, he mysteriously coughed a few times.

He took out another large design drawing.

Agnes was stunned when she first saw it.

"This, this, what is it?"

"This is the ultimate love story! Every man's dream! Sister, can you do it?"

"...Kishi, give me three years, no, five years, maybe, maybe, maybe, it can be done!"

"Alright, let's do it!"

Kishi was full of hope. He looked at this hand-drawn design, but he didn't expect that things that were impossible in his previous life now had a chance to be achieved.

Of course, one just needs to have dreams.

Kishi: "This prince just wants to pilot a Gundam in a different world!!!"

This was a Gundam design drawing.
