Esper Harem in the Apocalypse

Once Rudy had created a base, he slowly moved the island down and placed it on the base. Then, he came out of the sea and grabbed Le Bela on the way.

They landed on the island and looked upon the castle from afar.

"There are still some things left in the sea, but I will take care of them later. For now, let's focus on the castle itself," Rudy stated.

Lu Bela glanced around and asked, "Since you created a base bigger than this island, the sea level must have risen. It would bring catastrophe to the island and land nearby islands and continents."

"I already took care of that."

"How?"

"Just made a giant hole on the sea bed, so the amount of sea level that was supposed to rise is already settled at the level it was before."

"You created a trench deep enough to the size of this island?"

"My bad. I created multiple holes at safe distances, so…" Rudy raised his fingers and quoted, "Trenches. Now, if you are done worrying about the world and the climate, care to worry about my new home?"

Rudy asked with an annoyed sigh, seemingly he was in a hurry to deal with the matter so he could return to Maria before she got angry.

Lu Bela hugged Rudy tightly and said, "Let's go."

Rudy jumped in the air and flew over the island. They looked at the ruins of what was once known as the greatest and strongest Dynasty.

"Orcelona Dynasty. It was ruled by many different Emperors over the generations, but one era lasted long."

"Zenith Empire?" Rudy guessed. "Since the seller said she was the last surviving descendant."

"Yes. It ruled over this Dynasty for over twelve thousand years. It was also the last Empire to rule on it before it met its dismay. But until then, other lands were discovered, and everyone migrated to different continents."

"Twelve thousand years? Surely, you mean seven thousand years, right? Since that's what Kim said in the seller's representation of the castle," Rudy asked with a confused and curious look on his face.

"No, it's twelve thousand years. And the Dynasty is a lot older."

"Then why would you provide misinformation?"

Lu Bela looked at Rudy and asked, "Would anyone believe if we had said the Dynasty was that old?"

"Well…" Rudy pondered for two seconds and sighed, "Okay, you proved your point. They would probably say, 'There is no way they had the knowledge and equipment to create a castle in that era.' or something along the lines."

"Indeed. And even the seller didn't know much about it. I don't blame her. She had no idea she carried the ancient blood. She is so valuable, yet living a miserable life."

"Not anymore, though. I gave her sixty-nine billion dollars. Surely, now she can live without worrying about anything else in the world."

"Who knows. Money isn't everything in this world."

"Back to the topic, how long has this dynasty been submerged in the sea?"

"Rough estimate, five thousand years ago. Back then, there used to be seven Dynasties in total. Until one day, one of them sank into the sea in one night with no survivors.

From that day, the rulers gathered and decided to look for new lands in the world. No one knew the reason why the Dynasties were submerging, but they all thought that it was due to an increase in population and buildings on the land.

Mind you, everyone lived in harmony back then, so there were no wars and bloodshed. So all the humans did was wake up, farm, build, eat, sleep, explore, and breed. There was no drought whatsoever, and they had nothing to worry about.

The kings and emperors of all the Dystanties gathered every year on an island in between. Hundreds of thousands of them, and they all discussed how they could give back to mother earth.

When one land invented something, they would share it with others. When they discovered something, they would share it with another. Everything they did, they did together.

The rules and laws of that time were simple too. Since everyone was satisfied with their lives, crimes rarely happened— but they did happen. Some psychos don't need a reason to do evil.

However, natural disasters such as plagues, volcano eruptions, rising sea levels, food chain collapse, calamities, and catastrophes wipe out 10% of the world's population each year. That continued until the world's population had halved. Dynasties changed their rulers, and the emperors changed their Empires.

But they still lived on. Once they discovered new lands, they began to settle there. It wasn't as though they had never tried to search for new lands or they weren't advanced enough to inhabit a new land, but after decades and centuries, the world's structure changed.

The desert that was stranger to water and trees became mellow and green. The frozen lands where no one could survive became endless valleys once the ice had melted. The green land turned into ashes.

The sea became land, and the land became mountains. Everything changed. Nothing is the same anymore. Not… a thing. So the current human civilization lives on was once resting at the bottom sea until the world's structure changed and messed the sea level."

Lu Bela asserted with a distant smile on her face.

Rudy narrowed his gaze and asked, "You have seen it all, haven't you?"

"Yeah. I have witnessed the beginnings and ends of various human civilizations. Sometimes I pitied them, while the rest of the time, I was happy."

"Happy? I didn't see that coming."

"Most of the time, it was their fault, to begin with. Pointless bloodshed and never-ending wars, destroying natural resources, misusing the powers they were given…." Lu Bela sighed in disbelief and muttered, "They deserved to die."

"Hmm~" Rudy hummed in amusement and uttered, "I don't know how old you are, but you are from the era after the 'Great separation', right?"

"Yes." Lu Bela nodded in response. "I was created a few millennia after that."

"In fact…" Lu Bela looked at the island below and calmly uttered, "Here."

"..."

"This is my homeland."
