Explosions reverberated across the battlefield, as cannons and manifestations of abilities clashed with each other.

If the 69th Battalion and the Valkyries had initially thought that the Rigel Continent wasn't as dangerous as they expected, that was only because they had yet to experience a monster invasion during their stay.

Now, they finally realized how wrong they were.

The only reason why they hadn't been met with a full frontal assault by the Jinns was credited to the fact that the Dvalinn Federation had painstakingly learned the boundaries of what they could do and what they couldn't do with the limited manpower they had.

The "No Flying Ban" had come from a bitter pill that they swallowed in the past. Ever since that incident, they made sure to reiterate this rule whenever there was an outside faction or organization that planned to enter the Rigel Continent.

Unfortunately, this rule had not been taken seriously by the Valkyries who were part of Viola's squad.

Now, they were seeing firsthand the consequences of their actions.

Marion, who was also a Champion, fought as fiercely as she could, treating it as a way to atone for the mistake of her subordinates.

The Valkyries also knew that this incident was their fault, so just like their commander, they went all out and attacked with everything they had.

Wendell, the Monarch of the Elrod Clan, roared as he swung his trident forward.

The seawater rose up and unleashed countless Water Spears at the flying monsters who were attacking the Port.

The ability he gained was the ability to manipulate water, and the sea.

This was why the port was constructed a few miles away from the island. In the worst-case scenario, he would be able to fight and defend it with his abilities.

Even so, it wasn't easy.

It was as if all the Flying Monsters in the Rigel Continent had gathered to end all of them.

No matter how hard the defenders tried to fight back, the casualties were steadily rising, making everyone's faces turn grim.

But compared to the time when they first experienced this kind of assault from the Bird Man, they were lasting much longer than they originally expected.

The battleships of the Leventis Family, as well as the Central Government, were made to fight against Jinns and Majins.

Because of this, their cover fire decimated countless Jinns and Majins, giving their people at the port a bit of breathing space.

Even so, screams of horror and death spread in the surroundings as the Flying Monsters claimed their prey, dyeing the sea in the color of blood.

Suddenly, Wendell jumped forward and summoned a flying Manta Ray.

The Thrones of the three Prestigious Families swiftly followed since the Rank 8 Sovereign had finally made his move.

If they allowed it to descend on the island, almost everyone there would die, so they needed to block his attacks with everything they had.

Thirteen, who saw this from the side, frowned and gave an order to Jubei, who was currently on the Nautilus.

"Allow Manual Connection," Thirteen ordered.

"Manual Connection activated," Jubei replied.

Thirteen lowered the visor of his military armor and took control of the Main Canons of Nautilus. He was the only one who could pull off making quick calculations in real-time, allowing him to aim the cannons wherever he wished for them to attack.

"Cristopher, Colbert, protect me!" Thirteen ordered.

The two Captains didn't hesitate and moved beside their Commander and stood beside him.

Cristopher only summoned Brutus. He was afraid that if he summoned his newly acquired Roc, the Dvalinn Federation would mistake it for an enemy and kill it without mercy.

Suddenly, two Harpies descended from the sky and attacked the teenage boy from his right side.

However, before they could even come close, a black Chakram sliced off their heads without mercy before flying towards Thirteen.

A moment later, the Chakram transformed into a black snake, who immediately coiled around her Master's neck.

Tiona eyed the monsters who were aiming for her Master's life, ready to strike if they came within her striking range.

"Increase the output of Main Cannons to eighty percent," Thirteen ordered.

"Cannon output increased to eighty percent," Jubei replied.

Thirteen knew that this was the highest output that he could use at the moment because this was Nautilus' first battle run.

If the Main Cannons overheated, he wouldn't be able to use it for a while, which would be bad for their current situation.

'The Bird Man is too fast and too small,' Thirteen thought. 'I need to time this perfectly.'

In theory, the Rank 8 Sovereign and the Monarch were of the same rank, so they should be able to fight each other head-on.

However, Thirteen didn't like to take chances, especially since the three Thrones were also protecting Wendell.

The key to this battle was the downfall of one side's Powerhouse.

If Wendell lost, then everyone would die.

Thirteen's goal was to at least injure the Bird Man, giving the Monarch an edge in their battle.

As the teenage boy waited for the right opportunity, dozens of Wanderers were dying by the minute.

Several members of the 69th Battalion were also injured during the battle, but fortunately, they didn't have any casualties yet.

Thirteen had ordered them to summon their Night Wolves and hide under their bodies, while they used their assault rifles to attack.

The Night Wolves were Rank 4 Alpha Monsters, so they weren't easy to defeat.

They also helped their Masters kill those who were attacking them, but the disparity in number was simply too much.

It was like a giant mantis fighting against a hundred ants.

Even if it was bigger and stronger, it was still being overwhelmed by sheer numbers.

As absolute pandemonium took place around them, the Bird Man and the Monarch clashed several times in the air, with the Thrones protecting Wendell from the attacks of the Bird Man's subordinates.

Despite the efforts of the four strongest men in the Dvalinn Federation, their armor was bloody with the blood of not only their enemies but also their own.

The Bird Man, who was getting annoyed, decided to target one of the Thrones so that Wendell would have one less protector.

It had timed its attack perfectly, doing a feint, which Wendell thought was an attack on his right side.

But instead of attacking him, the Bird Man flew past him and aimed its spear at Hugo Rigg's chest.

Hugo, who had just killed two Rank 5 Monsters, didn't have enough time to defend himself from the Sovereign's attack.

Just as Wendell and the two other Thrones were about to come to his rescue, a blue beam of light streaked across the sky, and hit the side of the Bird Man's body, making it stagger mid-air.

Wallace, who was already in mid-swing of his trident, went for the kill, but the Bird Man flipped its body at the last second and evaded his attack.

Using its clawed feet, the Bird Man used the Monarch's body as a platform and kicked him away, allowing it to escape Ronald Rhodes' and Spencer Nightshade's follow-up attacks, which targeted its wings.

The Bird Man sneered, thinking that the humans had lost their only opportunity to deal him the killing blow.

But before it could truly feel good about escaping unscathed from a near-death experience, three beams of light collided with its right wing, shaving it off completely.

The Bird Man cried out in pain before falling from the sky.
