How to become a Demon Lord: The Former Hero's Journey as a Demon Lord!

Inside the castle, the head guard, Trevor, received a call from his subordinate. He excused himself and quickly went to the side to answer it. What he heard made his heart stop for a second!

"We're under attack!?"

Trevor accidentally shouted this in shock and everyone heard it! Trevor wasn't finished hearing everything that the subordinate was saying when the king perked up as he heard what was said!! Who would dare to attack them when the duke was visiting!? He immediately shouted to Trevor!

"Go out there and make sure that everything is in order! Tell Freya to raise the defense and don't let anyone enter the kingdom! Don't worry, Duke Winchester. Well make sure we protect you and the supplies,"

The king was very tense because he was afraid the attackers were after the supplies that the duke was bringing for them. He said the last part of his speech to Floid and Floid smiled as he took a sip of tea.

"Yes, yes. I hope you can protect me..."

Floid's grin turned bloodthirsty as he looked up at the king.

"I'm absolutely terrified,"

Trevor was silent at the side as he just kept on listening to what his subordinate was saying.

[Sir, it's the Duke's ships! Demons! They're demons on the Duke's ships!!]

Trevor looked towards Floid with wide eyes and he was about to shout but a sword suddenly flew through the air and stabbed into his forehead!!

Squelch!!

Floid grinned wider as Rosavellt blasted off the floor and charged straight towards the shocked Maryleen!

......

"Go into formation. Squad one and two, dive down now! Squad three and four, activate aviation mode! Squads five and six, stay on me! Let's throw these demons back to hell!!"

All the ships obeyed the order of the leader of the coast guard as they separated into three groups. There were two hundred ships in Aquinas and all of them were charging straight for the hundred ships that Floid brought! The leader of the coast guard was sure that they would win this! Their ships were made by the great magician Maryleen herself! No matter how much firepower the demons have on their ships they can never match up to our own! I doubt they can even make their ships fly! They are all just savages and there isn't a single one of them that can engineer a flying ship!

The leader had this thought in his mind as he charged straight for the demon army! The demons were still moving on water and the ships were all waiting for the command from Rizi. Rizi was looking at the ships from Aquinas with a smirk on her face. She should have known it would be like these. None of these ships can even match up to the ships her master designed!

"Prepare the [Propulsion Cannon]!"

Rizi shouted this to her ships and ten ships immediately opened up the front of their hull and a large cannon came out from the hole. Rizi rose her hand up and the cannons all started to release a deep hum as a great amount of power gathered there! Once she dropped her hand, the cannons released destruction!

Boommm!!!!

The cannons split the ocean apart as they flew straight for the ships coming towards them! There were sixty ships from Aquinas that were still floating on the water (the rest had either dived underwater or gone into the sky) and the cannons decimated thirty of them in a single instant!

The commander of the coast guards felt his eyes widen in shock as he saw half of his ships vanish! They didn't even burn and sink! They just vanished! He immediately swerved to the side with his ship as he saw them charging up another cannon! He shouted into his communication circle!

"Deploy evasive maneuver now!! Break formation and dodge! Squad four and five, charge up the artillery rounds!! Squad one and two double back and attack them from behind!!"

All the Aquinas ships that were still floating on the water broke formation as they swerved out of the way of the next round of cannon fire! The cannons released a great blast and the leader grit his teeth as he saw some of his ships go down again since they couldn't dodge fast enough! What the hell is this!? What kind of cannon can destroy a ship completely!? And they aren't even using their full force! They are only using ten ships to fire cannons and they are causing this much damage!? We have to attack them from above! If we keep staying on the water, then we will all die!

The commander didn't know how the demons were able to build a cannon that was so strong but he didn't let something like that bother him too much! He was a master at adaptation and this was just another thing he needed to get used to! He immediately told all the ships that were still floating on the sea to turn on their aviation system and take off into the sky! All the ships immediately went up and the commander shouted!

"Charge!!!"

Pyra smiled from her place on the ship. She was the one in charge of battles in the air so she took command from Rizi and all the ships obeyed her instructions. She put her hand to the side and then swung it upwards! All the dwarves that were driving the ships immediately understood the order and they split into two groups of fifty!

Half of them activated their magic barrier that prevented water from entering the ship before they sunk under the sea. These ships would fight against the Aquinas ships that went underwater earlier and Lilith would be the one to command them. Lilith gave the other maids a nod before she disappeared underwater with her ships.

The other half of the demon's ships activated the aviation system and immediately went to the sky!

The leader of the coast guard couldn't believe his eyes as he watched the ships coming into the air as well! This isn't real! This can't be happening! How did they get flying ships!? This isn't a technology that you can just build! It takes years to be able to build a single flying ship!

The leader grit his teeth and then he shook his head! He didn't care if they had flying ships! They were in the middle of a war! They have to fight no matter what! They are the last line of defense for the kingdom! They won't give up!

"Open Fire!!"

All the Aquinas ships immediately charged forward as they activated their cannons. Their red cannon blasters immediately swarmed the demon army! The demon army didn't just wait for them to come, Pyra immediately pointed forward and all the ships charged! Pyra might be a clutz with housework, but she was excellent on the battlefield! Her instincts for battle and her superior strength made her a force to be reckoned with in any situation and Floid knew she would make a good strategist for the ships!

Rizi looked up as she saw one of the blasts from the Aquinas ships strike the barrier that the demon ship was covered with. The barrier didn't even shake as it absorbed the shock and dispersed it! Her barriers wouldn't break because of those small cannons! They should have brought bigger cannons! The Aquinas ships also had barriers, but their barriers were very weak when compared to the demon ships! This battle had already been decided from the start! It was obvious that the demon army had the superior barrier!

The citizens in the kingdom were in a state of panic as they wondered what was going on!? They all heard the warning bells and they started to pack up for an emergency! They all knew that once the warning bell rings, that means that they are under attack! There is only one race that would dare to attack Aquinas and that is the demons! The demon army was attacking!
