Reincarnated as the Demon King's Son

"But I still cannot believe something like missiles or artillery doesn't exist."

"It exists," Stella said.

Bartrem and Mary glanced at her. "Really?"

"Believe me. I have seen how all empires rise and fall. That weapon exists, but I don't think it will be used in skirmishes. I once saw the pope of Montcresia use it before. I think it was called Divine Arbiter. It basically fired a thick golden light from the sky and vaporized everything nearby."

"The bible never said something like that," Mira said.

"Has your bible said something about angels coming out of holy light?"

"Yes?"

"That holy light vaporized the area around it before your angels secured the region."

"What about the Ceraisian Empire?" Mary asked. "Does the empire have that type of weapon?"

"It does. And it's very powerful."

"How powerful?" Aldred asked.

"It can almost reach every corner of the entire continent."

They all trembled in fear when they heard that.

"What's stopping them from using this weapon?"

"Other nations also have it. If you use it, they will use it as well."

Ahh… so it was that… Just like in modern earth. All the nations did not want to use nukes, because they knew they would be nuked in return.

"So they will never use this weapon?"

"Probably not. I have seen when the weapon first came out. Everyone was attacking each other, and it created nothing but chaos and death. No cities could be created, and no one wanted to stay in the cities, because they knew it would likely be bombed. Civilization almost stopped functioning at that time."

"What if the nation was invaded and about to lose?"

"Still unlikely. A losing nation still has people living in it. So unless the ruler wants to rule with an absolute iron fist, they will not use it. Not to mention their nation will receive backlash and face hell afterwards. But there is an exception."

"What exception?"

"If the ones invading are of a different race, there is a high chance that this weapon will be used. Humans enslaving humans is kind of acceptable, but if something else did that, humans surely would retaliate with everything they got. The same can be said for other races."

"Alright, enough about history," Bartrem said. "Aldred, can you make the golems?"

"We can only try."

Aldred started his experiment as the soldiers enjoyed their meal and sat down on the mat. They could do nothing to help anyway, so they relaxed while Bartrem and Aldred's women were watching closely.

First, Aldred created the small golems that will act as artillery shells. He put his mana crystal inside, and constructed the fire jet spell within.

"It's smaller than I thought," Bartrem said.

"It's 155 MM in diameter. We can make it bigger, but the golems won't be able to bring enough of it unless I make it bigger which as you know will slow it down."

"What if we give them a special bag?"

"We can do that for special artillery units that can attack for a long time. But we should maximize the golems without special treasures like that. Spacial bags are rare, and we cannot give it to every golems."

"But will this golem hold enough power to devastate the enemy? And why doesn't it have any legs?"

"It wasn't supposed to walk because it acts as artillery shells. It can summon a small pair of legs and walk, but it's too slow. As for firepower, see it for yourself."

The artilerry-shell golem shot out a jet of flame from below and flew to the sky before it detected its target—an ordinary golem.

The artilerry-shell golem nosedived and crashed against the golem before exploding right in its face.

BOOM!

A powerful flames spread out as a shock wave shook the grass and blew Bartrem's hair.

"It's more powerful than your fire ball. Around 5 times more powerful"

"Because it is. I put five fire balls in there. So what do you think?"

"It's powerful enough."

"Aldred, do we really need all these weapons?" Rachel asked. "We're not going to war are we?"

"Nope. But it's better if we prepare for it. But the fight in the future can be considered as war. There will be more enemies from what I heard."

Aldred looked at her, who seemed to be concerned, but not for her own safety. "It's okay Rachel. As long as we keep getting stronger together, nothing can break our family aparts."

"I have been with Aldred for around a year now," Bartrem said. "And I have not lost a single soldier. Look at our gears. Aldred gave us rare treasures all over our body and help us get stronger. Not to mention he has an undead army that can act as canon fodder."

"You say it like I am the only one that made this possible. If not for you, I would be dead by now."

Bartrem shrugged. "It was my duty to protect you at that time."

Aldred smiled. When he first came to the fort, he didn't even know how to kill someone, and froze in fright when he saw a corpse. Bartrem taught him how to be a soldier and he was thankful for that.

Rachel looked at the both of them and amazement appeared in her eyes. "Both of you have strong bonds."

"We all have strong bonds with each other," Aldred said. "Now, enough chitty chatty. Let's get back to work. Since the shell is already strong enough, I should work on the artillery golem."

"Aldred, we should decide what to call the golem shell. Is calling them golem shell fine?" Bartrem asked.

"Yeah, golem shell is fine."

"What about the golem that shoots this shell?"

"Hmmm. Should we call it DFA1?"

"What's that even mean?"

"Death From Above 1."

"Honestly, that sounds cool," Mareona said.

"Too complicated," Bartrem said. "Just call it artillery golem."

"Alright."

Aldred raised his hand and created a large humanoid golem.

"Make it bigger," Bartrem said. "We want the golem to hold at least 20 golem shells."

Aldred made it bigger, from 5 meter to 8 meter (26 ft).

"Is this enough?"

"Perfect."
