Demon Hunter, My Wife Is a Demon

The god-level killer in his previous life was reincarnated into a demon hunter who hunts demons and maintains world peace, and becomes the future ace of the organization in one fell swoop. Due to the inaction within the organization, he resolutely resigned and went to a border town to live the life of a mercenary. He even had a few demon girls accompanying him. "Zhang Tianxing! Are you, a demon hunter, worthy of us for doing such a thing?" Zhang Tianxing, who was asked, just snorted disdainfully. "Don't ask me, you should ask the demon girls around me, but I don't care if they can twist your head off."
