Reincarnated as the Demon King's Son

“Aldred, how did you do that? How did these golems use spells without mana crystals?” Zafrina asked.

“I use my own mana, and put it inside of them. There are limits to how many they can contain according to their size and materials though.”

“If I use mana crystals on them, they can have far larger capacities, and even regenerate their own mana. But I found something out.”

“What is it?”

“Look at this.” Aldred raised his palm, and then blue mist started to form on his palm, before it condensed into a crystal.

“It’s a mana crystal!” Zafrina exclaimed. “But it’s not an elemental type crystal. It’s pure mana.”

“Impossible!” Mary stared with widene eyes. “Mana crystals formed through condensation of the world-elements, and pure mana crystal was never seen before.”

Aldred smiled. “Just like you said, Mary. It’s a condensation of elements. I just have to condense my mana into a physical state.”

“That’s easy to be said, but almost impossible to be done,” Stella said. “Only someone who has great mastery over their mana is capable of doing that. And even so, it would require a great amount of their energy just to create one crystal.”

Mareona glanced at Aldred. “How many can you create?”_.

His smile turned into a grin. “This many.”

Mana crystals poured out of his hands and they fell onto the grass, pilling one after another.

They widened their eyes in shock when they saw that.

“This…” Stella was speechless. “You can use these in your golem?”

“Yes. They can now use some of my abilities as long as I construct the spell inside of them.”

“That’s cool, Aldred,” Bartrem said. “But explain to me how the golem knows how to have teamwork like earlier.”

“I am the one who controls them.”

“No wonder. You basically see everything from the side. Can they act on their own?”

“Yes, they can. They also have their own stats such as strength and intelligence. And they can level up as well.”

Their jaws basically dropped at that revelation.

Meanwhile, Aldred received a notification.

[You have learned mana manipulation]

[Mana Manipulation]

Pure mana with no certain attributes, weak by itself, but the smartest of mind prefer it for its variety of use.

“I want to make a golem army,” Aldred said. “Tell me how I should do it.”

Bartrem, Mary, mareona, and Sophia came into discussion. They spent the majority of their lives in war, and they knew the art of warfare very well.

Bartrem was especially a great leader and could always break through any obstacles through wits.

After the discussion, the three of them glanced at Aldred.

“First, we should divide the golems into three divisions,” Bartrem said. “Melee, Ranger, and Cavalry.”

“Of course each division will have their own sub-division later on, but I am sure you understand their task and capabilities just by hearing their names. Melee are golems that can fight face to face against the enemies and use close-range weapons to fight.”

“What kind of sub-division will there be?”

“There are many, but we will start with three. One is speed-type melee, the fighter, and then the tanker.”

“Can you tell me more about the fighter?”

“They’re basically the ones that can be put in any situation. They are not too fast or too heavy.”

“So they are ordinary golems?”

“Don’t underestimate the fighter-type, Aldred. It is most likely that you will rely on them more compared to the specialized speed-type or the tanker. From what I experienced fighting against your golem, the bigger they are, the heavier and slower they become. This means that the speed-type is easily destroyed while the tanker is too slow. Both of these types can only be used in certain situations, and it’s hard to use them effectively. Fighters on the other hand are easy to use.”

“But my golems are basically undying. They cannot be destroyed.”

“That is if everything goes well. When I make plans, I always consider the worst. Otherwise it’s pointless.”

“Right.” Aldred nodded.

“As for the ranger, I can only tell you to have the gunner as sub-division.”

“We can have something called Artillery sub-division.”

“And what is that exactly?”

“It’s a unit that specializes in attacking targets far beyond our sight.”

“You can make golems like that?” Bartrem widened his eyes. If Aldred could make something like that, the game of warfare would change forever.

“Well, I can put some fire spells into a golem, let it fly from point A to point B, and then explode.”

“So, a suicide attack?”

“Kind of like that. But I am planning to create a large golem that can bring a few smaller golems that act as the artillery shell.”

“Think of the smaller golems as arrows, but instead of having a fixed trajectory, the golems can change their course to attack its target.”

Bartrem and Mary trembled. If this idea could be realized… the balance of war would change.

Not only could the artillery be fired far beyond any weapons, it could also changed its trajectory. This meant that the enemy wouldn’t even know that they were being attacked before they exploded to pieces.

Wars did not have to be fought directly. They could send scouts, and then sent artillery shell towards a target.

“Now that I think about it. I don’t think I can call it Artillery units. It should be Missile units.”

“The same as the robots that attacked us?” Mareona asked. “I recall that those rockets can change their trajectory as well.”

“Yes. Similar to that.” Aldred did not tell them that he had a few scraps of power armor in his inventory. Not that he might need to use them though.

He could just sell them off at Duria or fix them if possible.

“So, Duria is capable of such weapons…” Mary sighed. “They are very isolated and it’s hard to obtain information about them. They don’t want to trade with us directly, and never want to share their technology.”

“Maybe they are scared of us. I heard their people don’t use mana in general, so they rely on this technology to protect their nation.”

Mary nodded in agreement.
