He saw her Mental World do this through his Mind Hunter Pathway. Then he attacked her mind with the Mind Hunter Pathway and the Killing Pathway combined.
He used the trusty Mental Stab Metac to create powerful mental attacks that stabbed into her mind. The Splitting Edge Metac was also used, and it worked well since this Divine Metac is capable of cutting everything it comes into contact with, be they elemental, physical, or spiritual.
He was giving this attack his all, even though she was already dead. On the other hand, her Mental World didn’t resist his attacks. Her Mental World acted as if it didn’t see his attacks or saw them but thought they weren’t threatening.
To be fair, the laid-back attitude of her Mental World was because it couldn’t resist at all. But Loki didn’t have mercy just because his target was helpless to resist.
He ramped up his attacks until all of his mental attacks scattered her Mental World and destroyed it. This sealed off reincarnation for her. That way, the secret of his power and capabilities will die with her here and now.
With this done, he got to work extracting her power core from her corpse. After the power core was devoured by Fenrir, this fulfilled the last requirement, and he officially advanced to rank 5.
This advancement was a little bit dramatic. This was because, as soon as Fenrir devoured the rank 5 Telekinesis Metac, the last piece of the puzzle in his mind was solved, and his colorful Mind Palace immediately solidified and became something similar to an energy well.
This change wasn’t exactly unexpected since the Mind Palace had already been amplifying his power and could use internal energy from the moment it was created.
The only thing that the energy well could do that the Mind Palace couldn’t do was possess Core Metacs and produce internal energy. As for the possession of energy threads and the amplification of his power, both his energy well and Mind Palace possessed this.
So this change had only finished what was started and turned the Mind Palace into an energy well by converting it into a Mental World.
As Loki experienced the feeling of possessing a Mental World, "What exactly is the Mental World? Is it a mental construct or a spiritual construct?"
He wasn’t sure about the answer to this question because the Mental World should be mental, but for some reason, possessing the Mental World unlocked the Soul Stat, which means he can now raise his soul above his rank, and it means that he will reincarnate.
There is also the fact that the Mental World now contains Metacs, which are physical objects. He doesn’t think this should be happening if the Mental World is a mental construct.
When he thought of this, he remembered one of the foundations of the power of divine beings, so he said to himself, ’Then again, the Mental World will become a Cave Heaven later. The Cave Heaven is a physical world, so maybe the Mental World is both a mental, spiritual, and physical object.’
As he was thinking about this, the miniature version of himself in his mind was strolling through his Mental World.
His Mental World isn’t like Lady Red’s Mental World. There are no flames anywhere. There is no Earth either. The ground beneath his feet is made of water.
So his Mental World is an ocean world. Everywhere he looks, he sees water. But the water isn’t right.
The water isn’t blue like one would expect. The water is white and viscous like milk. However, the water isn’t milk. This is because the water is corrosive.
So the ocean in his Mental World is an ocean of acid. Nearly everything that falls into it will be corroded and dissolved. Only the strongest materials can escape the fate of being dissolved.
He can see some of the things that escaped the fate of being dissolved. They were crystals made of gems of various colors and had been polished to the extent that they shone like diamonds.
That was what was at the bottom of his Mental World. At the top of his Mental World is the manifestation of Fenrir. This manifestation is a black hole.
The black hole in the sky is surrounded by five twinkling small objects. These five objects are his Core Metacs and Life Ability.
Even though his Core Metacs and Life Ability are Divine Metacs, they look small and tiny next to Fenrir. They appear to be as small as Earth revolving around the Sun in his past life.
The black hole is also exerting a terrifying gravitational influence on every part of his Mental World. While his Core Metacs and Live Ability appear to be immune to this gravitational influence, everything else is being dragged and pulled towards the black hole.
Even the large ocean below, which is much larger than the black hole, is not exempt from the gravitational influence of the black hole. The pulling force has caused the white acidic ocean to rotate and turn into a whirlpool beneath the black hole.
At the point right beneath the black hole, the white ocean rose into the air from the ground in a single pillar of twisting water to meet the black hole in the sky.
This time, the gems couldn’t survive. They entered the black hole and disappeared, never to shine or be seen again.
So the black hole is devouring the white ocean and everything inside it. The process is slow and has formed a balance that doesn’t put his Mental World in danger. Or it can be said that the process of the black hole devouring the acid ocean is what his Mental World is.
After walking around for a long while, Loki scratched the chin of the miniature self and said, ’As far as I can tell, the white ocean is the world. It is cruel, and only the best, strongest, and brightest can survive it.’
