Pain
A truly Immense pain.
Like tens of molten nails penetrating my skin slowly, no, it was the blood in the coffin itself penetrating my body.
It forced its way into my blood vessels and merged with my own blood, causing unknown changes to it.
I stayed frozen in my place, gritting my teeth and doing my best to ignore my instincts to teleport out of this place.
'As if I would give up for just that!'
If such pain was needed to become a little stronger, then I was willing to endure more of it!
Compared to the pain of forming my aether core, or compared to the pain of losing my family — this was nothing!
Additionally, even if just a small amount, Glutton was still feeling some of it.
[Ahhh, that fucking itch!]
Yeah, I was satisfied.
As the pain continued, I began to feel some visible changes in my body.
My senses were heightening, my nails and hair were growing, my teeth were sharpening, my muscles, skin, organs and bones were strengthening, and even my beauty was improving.
