Sunless, a soul reborn from modern Earth onto a devastated post-apocalyptic world, awakens the Divine Attribute System after 16 long years of suffering. Across monster-infested wastelands where humanity shelters in fortified base cities, powerful martial artists have emerged as civilization's greatest hope for survival. With his legendary system activated, Sunless gains a revolutionary ability: every defeated enemy releases attribute bubbles that he can collect and absorb, granting him their powers. Victory against a sword skill genius bestows Sword Skill Enlightenment and beginner sword talent. Defeating a blade master yields Blade Battle Technique and the Domineering Tiger Blade Scripture, granting mastery of blade intent. Encounters with gods transfer God Fragments and the Divine Consciousness Technique, awakening a god bloodline within his essence. Contact with the abyss grants Abyss Energy, transforming him into an abyss creature as his god and abyss bloodlines mutate into something beyond comprehension. With each attribute picked up, Sunless evolves from a powerless youth into an unstoppable force. His body transforms, his power expands, and his comprehension deepens. Gradually, an undeniable truth crystallizes: through systematic attribute collection, he has become invincible. This action-fantasy epic features Sonia as the primary female lead and blends martial mastery with romantic storylines. While primarily driven by high-stakes combat and cultivation progression, the narrative incorporates intimate scenes between the protagonist and his love interests, balancing intense action with deep character relationships.
