My ten-year marriage was a transactional lie, built on an astrologer's prophecy that my chart would ensure my husband's success. But on my birthday, he abandoned me to take his young intern, Anais, to the sci-fi festival I' d dreamed of for years. He came home smelling of her sweet matcha perfume, a green hair tie and a festival souvenir tucked in his pocket. He called me dramatic, said she was "fragile" and needed him. At our anniversary gala, meant to be his grand apology, I watched him kiss her passionately on the terrace during the fireworks display. He was still whispering promises in my ear, completely oblivious. That night, I left him the divorce papers and my wedding ring. But he tracked me down on my solo trip to Utah, finding me with my new guide, Casey. He punched Casey, then accused me of cheating. "You belong to me!" he roared. Just then, his phone rang. It was a video call from a hysterical Anais. "Howard, I'm pregnant! My parents are furious! They're demanding we get married immediately!"

Agent Alivia Sanford opened her eyes to the suffocating stench of wild animal musk and raw sex. She hadn't just transmigrated into a savage beastman world; she had woken up in the body of a 300-pound, diseased, and universally despised woman. Worse, the original owner had just drugged the tribe's strongest warrior, trying to force a mating. Now, the warrior pinned her to the cave floor with murderous fury. "You think you can trap me, you disgusting pig?" he snarled, ready to rip her throat out. After kneeing him and escaping, a "Super Charm AI" bound to her mind demanded she conquer her five designated mates to survive. But these men treated her like a walking plague. They mocked her bloated face, threw bloody raw meat into the mud for her to eat, and publicly announced they would starve her to death. Even her own family looked at her with utter disgust. In her past life, she was a legendary survivor who could have crushed these arrogant men with her bare hands. Now, she was trapped in a weak shell, threatened with soul erasure by a system if she didn't grovel for their affection. Why should she beg for love from beasts who wanted her dead? Looking at the five "-100" hostility scores on her system panel, Alivia coldly drew a mental cross over each of their faces. Enduring agonizing pain, she forced her bio-manipulation ability to violently purge the toxins from her fat body. She wasn't going to play their twisted game; she was going to find her own resources and make them pay.

I thought the Burch family gave me a loving home when they took me out of the orphanage. But when the global deep freeze apocalypse hit, my adoptive parents mercilessly kicked me out of the bunker to freeze to death. As I lay dying in the snow, covered in horrific purple frostbite, my adoptive sister Kendal walked past me in a pristine designer jacket. Around her neck was my only childhood possession—an antique gold necklace my adoptive mother had ripped off my neck to give to her. Kendal gloated, bragging that my pendant held a magical space with infinite supplies and fresh food while the rest of the world starved. I realized I had spent years emptying my life savings to fund their luxury cars and fake medical emergencies. They had drained my bank accounts, stolen my bloodline's heirloom, and used my magical lifeline to live like royalty while leaving me to die. I took my last ragged breath in that blinding blizzard, consumed by a toxic hatred. Why was I so hopelessly weak? Why did I let them take everything from me? Opening my eyes again, the painful frostbite scars were gone. My skin was warm. I grabbed my phone. The screen lit up: November 12. It was exactly three days before the world ended. When my adoptive mother called, faking a tearful emergency to demand another thirty thousand dollars, I smiled coldly. "Just tell me where to send the money, Mom." This time, I'm taking my space back, and I'm going to drain them dry.

The first sign I was going to die wasn't the blizzard. It wasn't the bone-deep cold. It was the look in my fiancé's eyes when he told me he had given my life's work-our only guarantee of survival-to another woman. "Kelsi was freezing," he said, as if I were being unreasonable. "You're the expert, you can handle it." He then took my satellite phone, shoved me into a hastily dug snow pit, and left me to die. His new girlfriend, Kelsi, appeared, wrapped snugly in my shimmering smart blanket. She smiled as she used my own ice axe to slash my suit, my last layer of protection against the storm. "Stop being so dramatic," he told me, his voice full of contempt as I lay there freezing to death. They thought they had taken everything. They thought they had won. But they didn't know about the secret emergency beacon I had stitched into my sleeve. And with my last ounce of strength, I activated it.

Halie woke up to a sharp pain and a terrifying reality. She was in a new body, her face covered in a hideous web of scars, and her spiritual power reduced to a pathetic D-Class. Before she could even process the memories of being framed, her bedroom doors were violently kicked open. Her sister Seraphina sauntered in with a venomous sneer, followed closely by Halie's S-Class fiancé, Jett. "Look at the disgrace of the Avila family. What a waste," Seraphina mocked, throwing a mirror at her bed. "I can't be tied to a cripple. As an S-Class, I have to break our engagement," Jett added, his gaze full of disgust. The nightmare didn't stop there. Her father called, screaming about how she had shamed the family name. He officially stripped her of her inheritance, froze all her accounts, and exiled her to the decaying Southern District to rot. To make matters worse, a cold, mechanical voice suddenly echoed in her skull, warning her of an impending genetic collapse. Without an immediate energy infusion, she would face total organ failure in thirty days. A ruined face, a treacherous family, a world that wanted her dead, and a literal death clock ticking in her brain. The original owner had died in absolute despair, a tragic victim of sheer cruelty. But if they thought she would just sit there and die, they were severely mistaken. Armed with a mysterious system and her brilliant scientist mind from her past life, Halie packed her bags. She chose the craziest survival quest: head to the slums, find the exiled, sterile S-Class "madman" Coleman, and cure him to harvest his life energy. It was time to start her counterattack.

The last thing I remembered was the blinding flash of my starship crashing. But instead of a rescue crew, I woke up tied to a wooden post, surrounded by hostile beastmen. My universal translator kicked in just in time to hear their priestess, Chelsea, declare that I was a cursed demon who ruined their hunt. To save the clan from winter starvation, I was to be burned alive. The flames were already blistering my legs, and jagged stones hurled by the crowd gashed my forehead. I barely negotiated a three-day reprieve to find them food, venturing into the deadly primeval forest. I found a massive supply of wild potatoes and even gained the protection of Bronson, a terrifyingly powerful saber-toothed tiger beastman. But Chelsea wouldn't stop. She labeled my food as poisonous, tried to sentence me to starve in a penitent's cave, and when my agricultural knowledge proved her wrong, she invoked an ancient law. She incited the tribe's savage warriors to fight over me, turning me into breeding property. I was a scientist offering them endless food, yet their primitive ignorance and one woman's vicious jealousy kept pushing me toward a brutal end. I was terrified, completely powerless against their monstrous physical strength. As five ruthless challengers drew their bone axes to claim me, I begged Bronson to leave me and run. Instead, he pulled me against his scarred chest and kissed me fiercely in front of the entire clan. "She is my mate," he roared, unleashing a soul-crushing aura. "Anyone who wants her, come at me together."

I was the adopted daughter of the wealthy Ruiz family, but the moment their true heir appeared, I was thrown away like trash. Not long after being kicked out, my adoptive father and uncle hired a hitman to stage a fatal car crash on Mulholland Drive. Pinned under an overturned Porsche with a shattered leg, I watched the hitman point a suppressed pistol between my eyes. "The Ruiz family sends their regards." Before this, my reputation had already been completely destroyed by a director, a pop idol, and a reality TV star, leaving me blacklisted and universally hated.
