Shoot
'It is still bigger than my soul. I have to shrink its size a lot.'
The Soul Cornea flashed, making contact with a part of the soul of Heima's Wisdom Parasite, absorbing some memory fragments. The soul retaliated by churning its memory fragments, turning them into sharp blades that diced the Soul Cornea.
The Soul Cornea blocked the attacks by turning itself ink-black, corroding the memory fragments that made contact. But, it still suffered some damage as the attacks were faster, the damage transferring before the corrosion could affect the other party.
The Soul Cornea healed itself easily, expending some soul energy. It now had a larger reserve of soul energy to use, having no longer needing to exert its influence after all the murkiness had been vaporised.
