The Rise of the Black Plain

The spaceship of the Black Plain Empire could not only fly through wormholes and the air but also navigate like a submarine.

When they arrived above the location of the submarine city, the group on it did what they had to do and entered the sea, still traveling at high speed.

It wasn't possible to sail at the same speed as they could fly through the air. But even so, it could still sail underwater at more than 500 kilometers per hour, and it could withstand the pressure of the water at the bottom of the sea.

In a matter of seconds, that ship passed through the dark zone of the sea and reached the deepest part of that place, where a group of gigantic Sky Whales were already moving against them.

"Those..."

"Aliens?" Some of the Demigods imagined this was the case when they saw this spaceship since no one in the Spiritual World had yet shown such development to be able to use this kind of technology.

But when they thought about it, the first to identify the invaders of their territory realized they couldn't be aliens. Otherwise, the world would be in chaos, and their people in the North Sea would have already warned them.

It even made sense for the aliens to attack them first when the time came for war, but a single ship, several years before their enemies arrived, couldn't be the work of the aliens.

"Who are you? Identify yourselves!" A level 96 whale said as he appeared in front of their city, while the spaceship looked like an ant next to these colossal beings.

Then, a hologram appeared on the front of the ship, another alien technology that Minos' group had been working on.

The ship's commander was the one who appeared in the hologram since the empire's technology was not yet good enough to work with beings very far away from the hologram.

This man, dressed in the uniform of the Black Plain Army and holding a Sky Whale tooth, introduced himself.

"Your Excellency, we are members of the Black Plain Army. We are here on behalf of our leader to invite you for a short trip to Dry City." He said, assuming a military stance with a serious look on his face.

"His Majesty Minos Stuart wishes to do business with the Sky Whale Tribe regarding technologies such as this spaceship I'm on. Please consider accompanying us."

Hearing about the Black Plain Empire and how this spaceship had been developed by Minos' people, the nearby whales couldn't help but be surprised and open their mouths.

'They managed to get that far?'

'Is it really true?'

They mentally communicated as they stood in silence near the ship.

That was an outpost from their tribe's territory, one of the outposts around their tribe's main city.

Minos' group of men would never go directly to the main city of these beasts without being taken there, as it could cause too much trouble. 

But since some of these whales were very strong, they had enough influence to decide to go to Minos' state and start a possible negotiation. 

One of the strongest there said. 'Don't be silly. That is the symbol of the Black Plain Empire. Can't you see that thing working right in front of you? I can clearly feel how strong this thing's weapons and defenses are!'

'Yes, this can't be a trick. But how did they do it?'

"That doesn't matter now. Apparently, Emperor Minos Stuart wants to give us this kind of technology... I think it's worthwhile for one of us to go to him and hear what he has to say.'

They agreed until the strongest one there, a level 96 Sky Whale, transformed into his humanoid version as he approached the ship.

"Very well. I'm ready to visit your leader and see what he has in mind."

With that, the tension in the area subsided before the creature entered the empire's spaceship, and it left as quickly as it had arrived.

That Sky Whale would be shocked to experience the spaceship's high-speed flight before the crew returned through the same wormhole as before, which would remain open until the end of the next hour when it would close naturally.

...

Less than an hour after the group left to test the empire's new spaceship, they returned to the same place they had left from!

Seeing the ship back and undamaged, the group waiting for the return of this crew celebrated.

That was especially true for the spiritual professionals involved in developing this vehicle, who were now thrilled to find that their recent adjustments were correct.

Minos, Ruth, and Abby also smiled as they hugged each other, happy for a successful test.

Meanwhile, they noticed that someone else was on it and that their men had also managed to attract a Sky Whale.

'It seems that my ship has attracted the interest of one of the strongest creatures in the world.' Minos thought to himself as he saw the spaceship landing at the place he had left from earlier.

He and everyone else made their way there as the entrance to the spaceship opened, and the first crew members waited to disembark next to the level 96 Sky Whale.

"Unbelievable! I can hardly believe I was in my tribe's territory less than 20 minutes ago!" The muscular man in the blue robes made from his own scales said in surprise as he looked around and realized that he really was on the Central Continent.

"Your Majesty, this is the Senior Olgran. He has agreed to come to the empire to hear what we have to offer the Sky Whale Tribe." The commander said as he introduced Minos to the sea beast.

Minos smiled at the 2.6-meter-tall man and said. "Welcome to my city, Mister Olgran. As for what I have to offer, it's the same as what I offer to my allies, like the elves and the dragons."

Olgran took no notice and asked. "Will what you have to offer to enable my people to build such spaceships?"

"Yes, with some minor differences, but yes. You will be able to do most of what you've seen."

"Okay, I agree to make a deal with you," Olgran said, ignoring almost everyone and staring at the spaceship as if he were in love with it.

"What did you say?" Ruth asked, not expecting this guy to accept their offer so easily.

"I'll take it to my tribe, and they'll accept it. Don't worry, if it's like your leader said, we'll accept any condition."
