How Did I, the God of the Underworld, Transform into a Girl?

'''[Transformation (Gradual) + No Romance + Game Invasion + Late-stage Cosmic-Level Game] After being trapped in a mysterious dungeon for half a month, Yun Lin inexplicably finds himself reborn just before the launch of the online game *Dawn of Daybreak*. This time, armed with memories of his past life, he takes the lead and secures the Awakening Stone, unlocking the one-of-a-kind hidden class—Nethergod, the strongest hidden profession on Blue Star. "I admit Nethergod is insanely powerful, but... why is Nethergod a female character?" Yun Lin is utterly baffled and on the verge of tears.'''
