Reincarnated as the Demon King's Son

The air-plane's sensors beeped frantically as it detected movement behind it. Turning just in time, it evaded a swipe from the blue sea dragon's massive tail, firing its machine guns in retaliation. But the creature was too agile, darting away before the bullets could strike.

From the passengers' perspective, they only saw a massive flying hunk of steel wreaking havoc in Autumnspell Fall.

"Tom, isn't that your father's airship?" Zerdar asked. "What is it doing?"

Tom clicked his tongue. "You guys might not be able to see it, but something actually possessed the dragon and the phoenix and try to attack us."

"What? Where?"

"They are invisible to you all."

Zerdar frowned and grabbed a pair of magical glasses before he put it on. The glasses glowed and he widened his eyes. "It's true! The dragon and the phoenix are fighting against that airship!"

"What!?"

In disbelief, some of the people who had special artifact began to use it while others casted a spell on their eyes. After doing that, they finally saw the truth.

The phoenix swooped down, a trail of flames following in its wake. The air-plane banked sharply to avoid the fiery onslaught, unleashing a barrage of laser beams that singed the phoenix's feathers. The mythical bird screeched in fury, circling around for another attack.

The sea dragon lunged towards the airplane, its jaws snapping dangerously close to the aircraft's frame. The phoenix swooped down for the second time, its wings trailing flames. The unmanned airplane tried to dodge the creatures' attacks, but it was quickly apparent that they were too powerful to evade.

The airplane's systems analyzed the creatures' movements, looking for a pattern or weakness. Finally, it detected a gap in the creatures' defenses. The airplane fired a barrage of energy beams, and one of them found its mark, hitting the magical fall below.

The energy disrupted the magical fall, sending waves of power rippling through the air. The sea dragon and the phoenix let out a deafening cry as they were thrown back by the force of the energy.

"So powerful! It can even fight against two mystical creatures by itself! Tom's father must be a great golem master and also a fantastic alchemist to be able to make something like that!"

Tom accepted the praise, but it wasn't actually because of the Armageddon's power that it was able to push the dragon and the phoenix, rather, it was because of the powerful A.I and scanners that were supporting it.

But. The two mythical creatures weren't so easy to defeat. Quickly, the both of them began to chase onto the airplane and let out a powerful elemental magic.

Boom!!!

The water vortex and the fire spear struck the aircraft, causing an explosion, and black smoke to come out.

"Oh no! The airship is crashing!"

"Tom, can you tell the train to speed up?" Elfie asked.

Tom looked concerned at first, but a second later, his lips curled into a smile. "Don't worry. My father is prepared for every situation."

Four massive advanced airplanes appeared in the sky, seemingly out of nowhere. They looked like they had come straight from the future with their sleek designs and advanced weaponry. The airplanes were so big that they blocked out the sun, casting a shadow over the surrounding area.

The airplane's systems alerted it to the presence of two large creatures: a massive sea dragon and a majestic phoenix. The airplane's programming identified the creatures as potential threats, and it quickly began to assess the situation.

"Targets identified. Order to eliminate confirmed."

The airplanes fired a barrage of missiles and energy beams at the dragon and the phoenix, causing them to cry out in pain. The creatures tried to defend themselves, but they were overwhelmed by the sheer force of the airplanes' attacks.

The dragon's flames and the phoenix's fiery wings were no match for the advanced technology of the airplanes. The creatures were completely destroyed to shreds, defeated by the sheer force of the airplanes' weapons.

This was one of the Mechanicum's greatest weapons. Should Tom need heavy firepower, Armageddon would be at the top of the list. But the Mechanicum was constantly developing new weapons, so they might surprise him in the future.

The airplanes circled back, scanning the area for any remaining threats. Finding none, they began to fly away, leaving a trail of destruction in their wake.

As the airplanes disappeared into the distance, people on the ground could only stare in wonder and awe at the incredible display of power they had just witnessed. The future had truly arrived, and it was a force to be reckoned with.

"Such power… it's not even funny anymore. Even five high Diamond Rank magicians could not for certain defeat these mystical creatures, but four of these metallic airships is enough to destroy them completely."

"Mind you. They are very expensive and time consuming to make," Tom said. To be honest, it wasn't that long nor expensive. The resources they had were enough to sacrifice one or two Armageddon. Any more than that would hurt him slightly though.

But as long as they could get the wreckage back, it should be fine. Tom already saw some heavy heavy helicopters coming from the distance to pick up the fallen Armageddon.

"Still, it is still amazing that your father can create something like this," Zerdar commented. "If we have just one of them, the war in my territory will become a lot easier as it can send reinforcements instantly."

"Maybe I should make a service for that. Sending reinforcements for payment."

Zerdar's eyes lit up. "Can you suggest that to your father?"

"Of course. My father loves money. But as this aircraft is a very important tool, we can only send it to only a select few noble families."

"I understand." Zerdar nodded.

"Now, excuse me. I need to go somewhere else."

"Where are you going?"

"Number two."

"Ehh… but Diamond Rank don't' need…" Zerdar didn't finish his sentence as he saw Tom walking away.

Tom entered the toilet, locked the door, and vanished.

The next moment, he appeared where the body of the dragon and the phoenix was.

"You two caused me a lot of trouble. But that is fine since I will be turning you two into my undead."

Tom's eyes turned dark purple as dark mist leaked out of his eyes. "Arise."
