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.
