The dragon's harem

"This is a gun." Lucia pulled a flintlock. "It was used since the old age by pirates and assassins to kill mages and fighters, but as you might expect, the kingdoms quickly took that technology and made it a common weapon." She pointed at the wall.

"If it was a staff, then the rounds are its components. You can smack someone with an empty gun, but that isn't the extent of its power." BAM! She fired a shot at the wall, and the bullet stopped without even denting it. The walls of the schools were reinforced with magic strong enough to stop basic spells and siege weapons.

"And since I know not everyone has a talent for magic, there is a simple 0-tier spell that can teleport small objects for less than a meter distance. It's pretty useless, but…" BAM! BAM! BAM! BAM!

"As you can see, with it, I can reload this thing instantly. Everyone should be able to learn 0-tier spells. Due to what happened yesterday, all of you would be provided with a gun and taught how to reload it with magic for safety. Of course, we'll provide training.

As Arad looked at her, he smiled. ^I should go back and teach Tina that 0-tier spell.^

"Giving us guns… are you sure that's safe?" A girl asked with a worried face.

"It isn't safe. But we enchanted all weapons with a tracing spell. We'll know when you fire them. And what you hit. And switching guns won't help you hide. All the guns can identify all the students, teachers, or if they are in the hand of an outside."

"I'm more comfortable with my claws." Matilda lifted her hand.

"Even if you don't need it, keep it just in case." Lucia returned to the board, "So, let's contentious. I told you about those guns now for one reason. We just finished learning about the magic component, and as you might guess."

"Another joint class." Arad looked at her.

"You're right, with the magic class." She smiled.

Arad grinned, "Since brother is there, I'll have to cook something special." He pulled Aisha out of his bag and sat her on the table. "Isn't that right?" He giggled.

"He's talking to that doll again…"

"What is he doing?... that's a doll. It'll never reply."

"He has that face. Stay clear from him and his brother. They are going to cause an explosion for sure."

Lucia looked at Arad. ^It's that face. He's going to do something terrifying again.^

****

"Yo…it's been a while." In the university's magic testing ground, Gojo approached Arad with a smile.

"Brother, I've got some interesting components to test."

As the two brothers talked, Lucia approached to inform them that they couldn't use anything above 1-tier as it was not needed. She specifically glared at Arad and Gojo as Gojo had already blasted a hole through a wall in a previous class.

"We'll be careful." Arad replied to her.

"Aron has already been working on a lot of components for magic. Jogo, don't go overboard with spells. You don't want them to get out of control. Start with something small and work your way up." She said, turning around and leaving to show other students what to do. It was clear to the students and teachers that if two students didn't need guidance, it was Jogo and Aron.

As Lucia and the other teacher started explaining to the students how to cast spells and what to do, Arad and Gojo went alone to their corner, a fair distance away from the other students.

"My teacher totally expects me to blow this place up." Gojo sighed, scratching his head.

"What did you do to him?" Arad stared at his brother with a worried face.

"I drowned the class with a water spell, destroyed a wall with a fire lance, and accidentally showed him a small ball of compressed mana that could blow a building off, and he was furious saying I shouldn't play with such dangerous and unstable magic." Gojo re-conjured the same ball of compressed mana, "What's so scary about this?"

"It might be nothing to you and me, but it'll kill any human that touches it. Remember, they think we're humans." Arad replied.

"Humans are so fragile." Gojo stated.

"No, we're too strong." Arad looked at him.

"Ho…" Gojo stared at Arad. "We're finally disagreeing on something, albeit is just different perspectives."

"Want to fight it over?"

"Nah, we'd just get yelled at. Let's test the component you made, then we'll try some chants and signs to see what we could achieve." Gojo smiled, pointing at an empty area they could fire spells into.

From his bag, Arad pulled a clear glass bottle. "First, let's start with this."

Gojo took the bottle from Arad's hand and looked at it.

A regular potion bottle, the glass looked a bit different; it was thicker, and on top of that, the bottle cap seemed glued shut with some kind of resin.

The content of the bottle seemed to be a clear liquid, and most importantly, it was freezing cold, far colder than anything he could've expected.

"Is this some special liquid to boost ice magic? How do you intend for me to use it with a spell?" Gojo turned toward Arad.

Arad had a smirk on his face. "Think again, I'll let you guess."

"It's a potion to drink before casting a spell?"

"No, I meant the first part. It doesn't buff ice magic." Arad's smirk grew larger, "It's honestly a bit scary."

"I give up. What is this?"

"It's a special liquid that boosts fire magic. The concept is simple thought." Arad pulled a second bottle.

"When you have a fire and want it to burn hotter and bigger, you fan it. And a while ago, Zephyr showed Aella that she could pick up flames with her wind to burn massive areas. So Aella tried to develop that and found a new technique. Which is to use a fire arrow spell to induce flame to her wind magic and create a massive burst of fire, like a fire tornado." He wiggled the bottle.

"I took that concept and tried to stretch it by attempting to compress air into a small bottle. With gravity magic, I managed to jam about twenty rooms worth of air in a bottle." Arad kept explaining, "But then Doma and Aisha noted that air isn't what fire burns hot. It's something in the air. So, with their help, I managed to isolate that substance and filled a bottle with it. This is the worth of around fifty rooms of air."

"So this is supposed to make flame burn really hot," Gojo looked at the cold bottle.

"And big…" Arad nodded, giving it a test.

Indeed, what Arad had made was a bottle of pure, liquid oxygen.

"Let's give it a try…" Gojo said with a smile.

"I'll do it with you." Arad stood by his side holding his own bottle. "Do as I do, we'll cast Firebolt together and see who makes the biggest blast."

"They'll yell at us. Did you test this before, you sure it won't get us in trouble?" Gojo looked at the bottle in his hand. "Fifty rooms worth seems a lot."

"It'll be all right. I didn't test it, but I expect the best it can do is double the spell size." Arad shook his hand.

"Doubling a spell's power is impressive enough."

"That's just speculation, we won't know until we test it." A spark of flame ignited before Arad's palm as he extended his hand forward, "Take your stance."

Gojo pointed a finger forward, conjuring a small ball of flames akin to that of Arad. "I already did. Let's have firepower competition."

"Before releasing the spell, make it so it carries the bottle with it without damaging it until the moment of impact." Arad explained how to cast it, and that fairly simple to follow, the standard way damaging spells were cast with components in the past.

[Fire bolt]

[Fire bolt]

SWOSH! The two firebolts took the bottles from Arad and Gojo and flew into the distance, hitting the ground.

ZAAAA-BOOOOM! A large burst of blue flames, a rose almost fifteen meters tall bloomed out of nothing as a wave of hot air expanded as a blast, ripping trees off and shaking the ground so violently that the students far away got thrown off their feet.

Arad and Gojo stared at the flames rising to the sky, sweating.

"We're getting in trouble for this." Gojo said with a scared face.

"I didn't expect it to be this powerful." A fire bolt usually takes an eight of a room when exploding, that is the amount of air it consumes to burn. Arad had shoved fifty rooms worth of oxygen into it.

Arad looked at Gojo with a scared smile as he pulled another bottle. "And I was thinking of testing this. It's the simplest matter I can make with my void, and it burns well." He indeed carried a bottle of liquid hydrogen.

Hydrogen and oxygen, that's rocket fuel. Arad and Gojo didn't know they were playing with something that had the potential to send a dragon-sized piece of steel flying out of the planet.

"Let's use them together." Gojo smiled, wanting to see how big of an explosion they could make before the teachers arrived.
