The entire group entered King Elbas' mansion and began to attend to their different tasks. The only ones really busy dealing with the mission's issues were Noah and King Elbas, but the other experts had to help them whenever the situation required it.
Noah's understanding of space was profound, even deeper than King Elbas. However, the expert had a lot of experience when it came to dimensional tunnels, especially those meant for existences that had just stepped into the divine ranks.
Noah had started to study space only after reaching the Immortal Lands and stepping into the eighth rank. He could claim that his knowledge in the field surpassed King Elbas, but that didn't apply when his understanding had to affect weaker existences.
The fact that King Elbas required all the help he could get didn't make Noah forget about his task. He had announced that evolving a weaker world was easy, but the procedure still needed preparations.
His new ambition could deploy a domain capable of enveloping entire Mortal Lands, and evolving them as a whole wasn't an issue. The problems came before that since there was a high chance that everything would crumble before his law could reach the ground.
The Demonic Deduction technique couldn't help the task since Noah had to stay far away from destructive intentions. The world needed to remain in one place for the dimensional tunnel to have an entrance. He knew that Heaven and Earth couldn't wait to remove their assets and spare energy, so he couldn't give them that chance.
His ideas eventually led to the Shadow Domain. Noah could create a bomb capable of releasing a dense wave of ambition at the center of the eventual planet or landmass and trigger the evolution before landing in that world.
Issues accompanied that idea. Noah couldn't just throw his raw ambition into a lower world. His law carried a power that the frail materials of the Mortal Lands couldn't endure. His bomb could very well destroy everything before spreading its evolving properties.
Noah had to start experimenting with one of the areas that he hated the most. He had to remove destructive power from his abilities to create something suitable for lower planes.
The process was extremely hard for someone who had spent his entire life walking every path that could lead to power. Having to forcefully remove some of the core features in abilities that he had perfected after millennia was annoying and went against his core, but his very survival depended on his success.
Noah's separate space had never stopped containing vast stashes of magical beasts' corpses and other materials. Some of them had even started to accumulate since his power had ended up advancing too quickly.
Piles of Soul Stones also filled the insides of his separate space. Those rocks contained chaotic laws that could theoretically gain different true meanings, so finding materials for his needs wasn't a problem.
Noah's experiments were rarely safe. Stuff often exploded, but the dark world prevented the shockwaves from reaching the golden walls of the mansion. Still, his ambition continuously flowed out of his technique, and the hall that King Elbas had appointed to him eventually turned completely black.
The mansion was relatively resilient to his ambition due to the already incredibly high quality of its materials, but the blackness didn't stop expanding anyway. It soon invaded other halls, and it didn't limit itself to reinforcing the overall structure.
The other experts didn't mind that event. The black landmass inside the sky carried Noah's ambition, so everyone knew or had learnt to accept the beneficial effects of that power.
King Elbas felt annoyed to see Noah's ambition tainting his item, but he didn't do anything about the matter. After all, those changes were clear improvements that benefitted the entire group.
Yet, the constant empowerment of the ambition eventually gave birth to a minor issue that King Elbas didn't hesitate to show to Noah.
Noah was tinkering with a large black metal sphere that was three times his size. Mechanical arms made of dark matter modified its surface and added or removed materials whenever something off appeared. The item seemed stable, but a few trails of grey smoke eventually came out of the structure.
'Another failure,' Noah thought before waving his hand and cutting the item in half.
A dark rotating mass came out of the center of the severed sphere. That chunk of energy was a special version of the dark matter that had tried to replicate the effects of Noah's ambition. He was basically attempting to give a proper shape to the invisible power of his law, something that was impossible at his level.
'It's still too powerful,' Noah sighed in his mind. 'The issue isn't even the dark matter since I made it harmless. I need to work with the higher energy a bit more and force it to suppress part of the ambition's power.'
"I can hear you," Noah revealed while he remained immersed in his experiments.
The dark world that had filled the entirety of the hall made him aware of everything that happened in his surroundings. Even the creator of the mansion couldn't sneak up on him.
"Do you mind if I shield the mansion from your law?" King Elbas asked while flying through the darkness and landing next to Noah. "You wouldn't have complete freedom here anymore, but I would be able to stop you from ruining my item."
"Since when does the great King Xavier Elbas see improvements as negative outcomes?" Noah mocked the expert while continuing to study his ball of dark matter.
The solution was close. Noah obviously understood that the approach would give him important insights concerning the last step of the eighth rank and the path ahead, but his focus wasn't on that. He only wanted to survive for now.
"They are indeed improvements," King Elbas exclaimed, "But they can be annoying."
Noah grew curious at that point and turned toward the expert. King Elbas was holding a hexagonal golden crystal in his grasp, and faint glows came out of its surface. A few dark spots had appeared in its insides, but they didn't seem to affect its functioning or light.
"It seems fine to me," Noah commented.
"I told him!" A shrill female voice suddenly came out of the crystal and startled Noah. "I'm fine, father. Why do you take that fact that I developed a thinking mind so bothersome?"
King Elbas didn't reply. His eyes remained on Noah, who slowly recovered from his astonishment. He didn't expect the crystal to speak, especially since the dark world didn't sense any trace of life coming from its insides.
That feature ended up making Noah understand what had happened. The core of the mansion had developed a will due to his ambition. King Elbas didn't seem too excited about that.
"Well," Noah commented once he regained his focus. "You can always give her to Second Prince. They might be happy together."
King Elbas glared at Noah before heaving a sigh and announcing his next actions. "I'm putting a shield around your hall. Sending information and visiting you will be difficult with it, but you can still exit the structure whenever you like."
Noah shrugged his shoulders. He didn't really care about that. He only needed to complete his task and return to the higher plane. Everything else didn't matter right now.
