Jack's hands began to shift. His fingers elongated slightly, becoming more defined.
His fingernails underwent a transformation, developing a hardened, claw-like appearance. While not fully developed, these appendages exhibited a distinctly more predatory nature than typical human nails.
The demon blood that covered his form seemed to accelerate the process, as if the ancient essence within the liquid was responding to Jack's will with perfect obedience.
His eyes began to change.
The yellow-orange gradually shifted, intensifying and becoming more vibrant. The iris expanded, filling more of the visible eye.
The vertical slit then manifested, a transformation so fluid it appeared to be an inherent progression rather than an extraordinary event. His eyes assumed a reptilian, dragon-like quality, a complete transcendence of human form.
A system notification bloomed across Jack's vision:
[Contract State Activated]
[Power Output: 80%]
[Damage Output Increased: 800%]
