Anna's first true test of survival begins the moment she is sucked into a dangerous B-Rank dungeon break right after waking from her three-year coma. Dressed only in tattered hospital clothes, she is forced to navigate the dark, desolate cavern of the Abyssal Caves, a place where she was originally destined to be a helpless victim. Utilizing her meta-knowledge of the novel, she immediately gathers rare Everose Lilies and Rotten Heart Roses, unlocking the Gatherer skill and gaining powerful stat buffs. When a massive swarm of poisonous Abyssal Dweller Pill Bugs corners her in a dead end, Anna does not panic. She consumes her gathered crystals, boosting her stats temporarily, and brutally fights back with improvised bug carapace armor and stingers. In the heat of battle, she purchases the Little Rabbit's Fearlessness and Crafting skills, successfully forging a high-quality poisonous stone spear to pierce through the incoming wave of monsters. After slaying over a hundred bugs, she faces the colossal Abyssal Dweller Queen, a terrifying D-Rank boss. Instead of relying on her brother to save her, Anna tames a rare, highly agile bug named Violet, using its silk production to trap the queen's scythes. With her newly crafted purple insect-themed armor and shield, Anna coordinates with her new pet, severing the queen's limbs and delivering a fatal blow to her brain. This miraculous victory earns her the favor of several watching constellations, who shower her with valuable plot points and the legendary Jester's Reverse Fortune privilege. Her luck is permanently reversed to a positive state for all calculations, turning her into a potential powerhouse. After the battle, she confronts the dim-witted Demonic Human Han Soo, using her newfound venom secretion and the powerful Thanatos's Broken Scythe to decapitate him. She then consumes the Holy Sunlight Pill, permanently restructuring her body to awaken the Seven Colored Sun Physique and unlocking her Ki stat. Yet, her triumph is short-lived as she hears the terrifying roars of approaching beasts, realizing that her presence has attracted the attention of a much larger, monstrous threat lurking in the depths.

Determined to grow stronger before the catastrophic Second Awakening begins, Anna utilizes her loyal retainer Sepa, the sealed Egyptian millipede goddess, to open an unreleased gateway into the ancient tombs of Egypt. Upon entering the unreleased dungeon of the Egyptian Death Gods, Anna is immediately confronted by the manifestation of Anubis, the Black Jackal that Judges the Dead. Anubis declares her unworthy and subjects her to the Weighing of Hearts Ceremony, a rigged trial designed to doom mortals. However, Anna exploits a loophole by allowing Sepa to temporarily possess her hollowed-body, boosting her stats to astronomical levels. In a flash of speed, she slices off Anubis's arm, interrupts the ceremony, and steals his Divine Weigher of Hearts and the Feather of Truth. She then uses her reverse luck cheat to synthesize these relics with a high-rank crystal, creating a double S-rank Anubis Divine Magic Crystal. Upon absorbing it, she permanently acquires Anubis' Judgement and Ruler of the Dead skills, alongside the Death's Little Sister privilege. Turning the tables on the god of death, she activates Anubis' Judgement, forcing him into a balanced state that drains his power by fifty percent while boosting hers by five hundred percent. With her newly summoned stone guardian and her pet Violet, Anna pummels the weakened god until his manifestation fades away in utter humiliation. She then enters the treasury of Osiris, passing Isis's unique trials of defeat and ignorance by refusing to fight and acting foolish. She synthesizes the Osiris Eyeball with the Feather of Truth, obtaining the triple S-rank Divine Eye of Truth, which allows her to copy and fuse skills. She even forces the low-rank administrator Charlotte to grant her a divine contract with Isis, securing her own cosmic backing. But as she returns home, she realizes the sky is beginning to darken with the shadows of the coming apocalypse, and her actions have drawn the ire of the higher-ups.

Anna's intervention in the timeline takes a compassionate turn when she seeks out Dan Baihe, a tragic girl destined to become a ruthless villainess after losing her family to a dungeon break. Arriving at the Flea Market, Anna witnesses Baihe being abused by her stepfather, Hector, just as a high-difficulty Frozen Graveyard dungeon break occurs. Separating from her overprotective brother, Jack, who goes to fight his former tormentor Rick, Anna uses her shadow wolf summon to track Baihe into the icy wilderness. She finds Baihe on the verge of freezing to death while being tempted by a demon's contract. Anna purifies the demonic influence, rescues Baihe from a giant glacial wolf, and purchases a D-Rank Super Growth Package to sponsor her. This unlocks Baihe's S-rank skills, Frost Queen and Great Sorceress, transforming her into a powerful magical ally. Together, they fight the Abominable Yeti King, where Anna undergoes a stunning transformation into the Seven Colored Heavenly Sun Cat Princess, using her enhanced physical stats and sunlight beams to decapitate the beast. They tame the mother wolf's pup, naming him Snow, who quickly awakens his own physique and Ki stat. When Hector reveals himself as a mutated octopus demonic human possessed by Leviathan, Anna and Baihe combine their powers. Anna copies Baihe's Great Sorceress skill, and together they execute a powerful Yin and Yang rotation spell, freezing and incinerating Hector. After the battle, Anna uses her Maiden of Life privilege, sacrificing fourteen years of her lifespan to revive the deceased paladin Henrietta. Though they survive the ordeal, the sky suddenly trembles as a massive frost dragon emerges from the gate, forcing Jack and the local hunters to engage in a desperate battle. This victory rewrites the tragic future, turning a destined enemy into a loyal companion. As the dragon falls, Anna realizes that her actions have permanently altered the course of the novel, drawing the attention of the Blood Empress Scarlet, a powerful vampire incarnation who harbors deep interest in her brother.

The ultimate clash begins during a newbie hunter training drill when the Seventh and Eighth Apostles of Death, Beelzebub and Bael, manifest ahead of schedule by planting demonic crystals throughout the ruins. Anna teams up with Baihe, Kevin, and Annabelle, the sister of the villainous Heisenberg. After clearing a goblin settlement, Anna uses her Eye of Anubis to peer into the memories of the deceased goblin chief, discovering a massive underground mine of Demonite. Deep within the cavern, they confront Bael, the King of Wickedness, whose presence paralyzes her companions. Anna uses her reverse luck to synthesize a purified version of the legendary sword Gram, turning it into a triple S-rank Divine Dragon Slaying Heroic Sword. She activates Anubis' Judgement, balancing Bael's power and summoning a giant stone golem to crush him. She then uses her cat princess transformation to obliterate Bael with heavenly sunlight blades, forcing the apostle to retreat to hell. However, Heisenberg appears and forcibly triggers Annabelle's demonic spider transformation. Anna utilizes a synthesized Sanctification Elixir to purify Annabelle, saving her life and taming her as a sponsored ally. Suddenly, the sky splits open as a massive black castle manifests, summoning Astaroth, the Tenth Apostle of Death, who merges with Neberius and Aim into a chimeric beast. Jack arrives to fight the monstrosity but is brutally beaten by their combined demonic might. As Astaroth prepares to deliver a fatal blow to
