After dying as an orphan in a devastating world war, Keith finds himself unexpectedly transmigrated into his favorite novel, Fallen Mages.

But instead of a fresh start, he’s thrown right into the chaos of the great war between the Mages and the Negators—a brutal conflict destined to end in humanity’s destruction. Armed with the grim knowledge of their impending doom, Keith braces for the worst.

Except fate had other plans.

[Congratulations, you have obtained the Weapon Summoning System.]

"Weapon...? Summoning...? System...?"

"You mean weapons like guns and grenades? Like the kind that goes BOOM?!"

"HELL YEAH!"

With this newfound power to summon modern weapons, Elon discovers that these arms are the only tools capable of striking fear into the Negators and giving his kingdom a fighting chance. From simple guns to devastating missiles, Elon’s arsenal grows stronger with each battle.

Determined to rewrite the fate of this war-torn world, Elon sets out to transform his once-weak kingdom into an unstoppable force. Along the way, he questions everything:

What’s wrong with conquering other lands if their rulers were never worthy in the first place? What’s wrong with using power to unite the broken?

"An AK-47 can't kill the Third Order Commander? Fine...! Launch the Bazooka!"

"The Great Archdemon of Death survived the grenades? Summon the Rocket Team and fire the missile!"

"A Twelve-Winged Demonic Dragon shrugged off the RPG-7? Let's introduce it to a volley of Javelin Missiles!"

Conquering the world won’t be easy, but with his system, unrelenting ambition, and growing army of allies, Elon is ready to take on every foe—and claim his destiny.

Join Elon in his explosive journey as he builds the strongest, greatest, and most fearsome kingdom this world has ever seen.

The walls were as high as the former clay walls, and they appeared stronger, just as expected. Even Ser Donns saw the clear possibility of the walls standing strong, as no defects had emerged since the commencement of the construction. He felt a slight relief.

Still, he wouldn't trust such a strange invention so easily. The wall's durability would have to prove itself.

"I told you, Ser Donns. You just choose to cling to the old ways of life. As the world progresses, so do its inhabitants. The clay wall isn't strong enough to save us," Queen Arya said, turning to another knight.
