The S.I.N. Phantom

Game Story:

Due to rapid technological development, humanity’s endless exploration of the universe through AI led to the emergence of the "Ghost Gate." This gate connects to a mysterious realm known as the Netherworld, where humans have witnessed bizarre and otherworldly entities never seen before.

However, the Netherworld subjects the human brain to a unique force field, causing severe neurological damage. This phenomenon is classified as:

S.I.N. (Synaptic Instability Neuro-level) — colloquially known in the underworld as "Karmic Burden."

Yet, you possess a rare and extraordinary constitution known as the "Mystic Yang Bloodline." Not only are you completely immune to the effects of S.I.N., but you can also inject your Pure Yang Primal Essence through Dual Cultivation to help humans purify the demonic corruption within them—and even skyrocket their cultivation levels! Even the female Yokai desperately crave your Pure Yang Essence to balance out their own pure Yin demonic energy.
