In a way, the mental space was its own world. It had rules, stuff in it, and now he was adding aspects to the Immortal Spirit that would help him in the future. Like a natural resource.

So, it was only right that he applied the principles of [Reality Warp] and [World Crafting] to his own Immortal Spirit to make the changes.

Not the skills, obviously. But the concept behind them.

If he imbued his Immortal Spirit with the Fundamental Rules of Life, Creation, and Mana Manipulation, with a focus on regeneration, he should be able to turn it into a massive lake of power that would passively heal him in mind and body. Actually, he had shaped it like the World Dragon, so making the essence of it more like the World Dragon's breath, which was already a life and nature type effect, might be a great idea.

But that also made him wonder if it might be a better idea to embrace a little bit of every one of the beasts into his Immortal Spirit.

They were all part of him, even if their spaces were separate.

Somehow, it just didn't seem right. The System led him in a specific direction, and it wasn't tied to the beasts that he had chosen, so it was likely to go in a more personally focused direction.

With that in mind, the plan to give himself regeneration based on the Fundamental Rules sounded like the best idea.

He had a pretty good grasp of many of the Rules now. Even if most of that was gathered from the beasts as they studied. But he could add all sorts of things to the Immortal Spirit if he wanted.

But how did that saying go? "Too many chefs ruins the soup." It was better to keep it focused and on target, instead of risking ruining the 'flavour' of the change.

Before starting anything, Karl carefully considered just what he wanted his Spirit to be like when he was finished.

The goal was to have an Immortal Spirit that would save you if your body was destroyed, so he was reasonably certain that regeneration was the right plan.

He also had Chaos-based regeneration from the Void Body skill that would let him reform from mist if his body was destroyed.

That sounded like just the sort of thing that an overpowered Immortal should be able to do. Not waiting for someone to resurrect him from his Soul alone, but being able to full reform and regenerate if his body was destroyed.

But that meant he would also need a bit of protection for his Immortal Spirit itself.

Spreading it out like he did would save some of it, as most skills wouldn't target him through time, or affect the fifth dimensional portion of his soul. That would allow him to save a bit of himself to regenerate from, even in the most dire of situations.

But a little focus on giving himself a presence in the Chaos Plane wouldn't be wrong.

Splitting his essence just enough to access, but not enter, the Chaos Plane. That would let him manipulate his rescue skills to throw his damaged soul somewhere safer than where he was.

Then, he could wait to regenerate and use [Planeswalker] on a portal to come back.

Overall, it wouldn't be a terrible safety net.

The only question was how he would do that. The Immortal Spirit didn't really want to be linked to anything but his Power Matrix. However, the matrix was based on the Chaos Dragon.

There had to be a way.

However, the more that he thought about it, the more that he realized he simply lacked the knowledge and power to manage such a thing. It wasn't something that he would manage without finding a specialty skill to assist him.

It simply couldn't be baked into his Immortal Spirit.

He could, however, evolve his Immortal Spirit through the Void Stage while giving it the ability to regenerate him from pure energy. That was something that he could do.

It was just the forcible shift between planes that didn't seem possible at the

moment.

Perhaps for Cara, it would be. But not for him.

So, Karl got right to work designing the change to his Immortal Spirit. It was like a runic inscription, in a way, and he even designed it with runes, as that helped him visualize the effect that he was trying to create.

The Fundamental Rules, imbued with the essence of World Dragon breath to match the shape of his Immortal Spirit, and return life where there was none before.

If that wasn't enough, then nothing would be.

The real challenge started when Karl tried to actually change the Immortal Spirit.

It wasn't a matter of power. He couldn't simply pour energy into it and convert the whole thing with updated Soul Energy. Instead, he had to inject the change into the ocean of power that was his Immortal Spirit, and then wait for it to disperse so that it wasn't rejected.

A little bit at a time, so that the change was integrated.

This was not going to be a quick process, but it wasn't a difficult one, and he could do it in the background as long as he didn't need one hundred percent of his focus for something else.

It would also progressively increase his regeneration rate as he finished it, and it would give him a solid base to work from when he finished and wanted to solidify the Immortal Spirit for Ascension.

With the process started, Karl focused on the Elder again, to see how the man responded.

"I take it that you've picked a direction?"

Karl nodded. "Using the Fundamental Rules to create an ongoing regeneration effect from the Immortal Spirit. I had the understanding to make it regenerate both itself and my body, so I should be able to recover from most things, I

believe.

I'm already quite good at that, with multiple regeneration abilities, and an advanced constitution.

This is just a bit of added protection, in case something hits me harder than I could normally recover from."

The Elder chuckled. "I see that the chaotic nature of the badger is not all a bad influence on you. You have developed a healthy level of caution, despite your clear intention to do things that might leave you as no more than a fragment of

a soul." "What can I say? It's a gift."
