With Echo’s riddles guiding her and the Ultimate Power System enhancing her body, mind, and strategy, she is determined that this time, nothing will stop her — no betrayal, no undead horde, no past mistakes.

Scarlet never believed in destiny—until she died. Now bound to a mysterious system, she awakens in the bodies of betrayed women across countless worlds. Her mission is clear: avenge the fallen, slap the traitors, and conquer the hearts of different untouchable men. From an academy ruled by gods in human form to kingdoms dripping in blood and betrayal to glittering cities where power is bought with desire—Scarlet must weave vengeance and temptation into every step she takes. She is no saint. She is no savior. She is the temptress who thrives on revenge, a woman whose charm is as lethal as her kiss. But with every world, every mission, and every heart she wins… Scarlet begins to wonder. Is she the player in this game of fate— Or the one being played?

I'm the fake heiress of a wealthy family. The system has given me three conquest targets to choose. As long as the affection score belonging to any of them becomes full, I can change my predestined death at the age of 23. But I've completely failed in my mission. The conquest targets have fallen for the true heiress, Evelyn Swanson, who has reunited with the family at the age of 18. As long as Evelyn says something, they can easily aim their malice and hatred at me. That's why I choose to take my own life in advance. Strangely enough, everyone is filled with remorse after I die.

My best friend, Clara Wilder, has baked an apple pie for me. But I don't hesitate to give it to my pregnant dog. That's because I've gotten reborn. In my previous lifetime, Clara had bound the Fertility Transfer System to me. If I were to eat the food she made, the baby I was pregnant with would be transferred into her womb, and she would be the one giving birth to them. Clara had married into the wealthy Gray family. For three generations, the Grays were only able to produce one heir each. That was why her in-laws desperately needed her to bear them grandchildren. Since Clara couldn't get pregnant at all, she decided to target me, her newly-wedded best friend. I went to great lengths just to get pregnant every time, but right after I ate the food Clara made, I'd go through a miscarriage by accident. Just like that, Clara was able to give birth to four sons in a row. She became the apple of her in-laws and her husband, Colton Gray's eye, which made her ego swell like mad. In the end, Clara and Colton hatched a plot where they accused me of cheating on my own husband. With my reputation flushed down the drain, I got kicked out by my in-laws. In the end, I starved to death on the streets without a penny under my name. At the end of the day, Clara wants children very badly, doesn't she? After I get reborn, I decide to give her some special "babies".

I suffered from severe skin hunger syndrome. Every waking moment, I wanted to cling to Charles Hansen. At night, I craved his touch even more obsessively. In Oakhaven's social circle, everyone knew me as the clingy, brainless rich wife. When I once again insisted on tagging along on Charles's business trip, a series of floating comments suddenly appeared before my eyes. [The cannon-fodder wife is at it again. She just has to follow him and ruin this client meeting too. The moment the male lead comes back, he finally files for divorce.] [She's unloved by both parents, emotionally unstable, and suffers from skin hunger syndrome. In the end, she develops depression and dies alone beneath a bridge.] [Good thing our heroine saves the deal and helps the male lead secure the client. This is also when he starts falling for her.] [I can't wait for the romance arc! Cold CEO x secretary is such a perfect pairing. Can this annoying side character disappear already?] I slowly looked toward Daisy Allen, the secretary waiting by the door to leave on the trip with Charles. Then, for the first time, my arms loosened from around him.

They buried him under a blood-red moon. Chains of silver and blessed iron pinned his broken body to the earth, sealing his power, erasing his name. To the pack, he was a failed Alpha. To the coven, a cursed vampire. To the world, he was a mistake that deserved to die. But monsters don’t stay dead. When Alpha opened his eyes again, he wasn’t in the grave—he was in the body of his weakest self. Eighteen years old. Rankless. Powerless. His wolf silent. His vampire blood thin and starving. The memories of his execution burned behind his eyes like fresh wounds. Reborn. A second life… and a second chance at vengeance. This time, he felt it—the system etched into his soul, ancient and cruel. [Hybrid Core Detected] Bloodline: Vampire / Werewolf / Unknown Status: Severely Suppressed Level: 1

My new next-door neighbour was a total hottie. He fixed my plumbing and brought over baked goods, basically the perfect gentleman. However, I could see a bright red stat hanging over his head. Malice Level: 1,111 It could only mean he was out to get me. One night, he snapped my stalker’s wrist, and red digits reset to zero. Somehow, his murder meter turned into a pink possessiveness score of 9,999+. He wiped the blood off his hand, his tone eerily gentle. “Who gave you the right to touch my prey?”

My boyfriend had just gotten home from a long day at the construction site when I demanded that he go out in the pouring rain and buy me a box of premium cherries. His voice was tired. "We're running low on money. Rent's due tomorrow. How about strawberries instead?" I grabbed a throw pillow and hurled it at him. "Get out, you loser!" After throwing him out, I curled up on the couch and sulked. Then a stream of floating comments suddenly appeared before my eyes. [This woman has no idea she's calling a billionaire heir a loser! He only ended up working construction because he lost his memory after being set up!] [His fiancée will find him soon. Once he regains his memories, he'll discover this woman has been lying to him all along!] [This spoiled brat is already pregnant. Later she'll use the baby to cause trouble, but she'll be killed right after giving birth, and the child will be abused too!] I froze. My hand instinctively moved to my stomach. Pregnant? At that moment, the front door opened. Landon Pierce stepped inside, soaked from head to toe, a box of premium cherries clutched in one hand. He looked at me nervously and spoke with careful hesitation. "I spent the last two hours delivering food orders so I could afford the box of premium cherries." He held it out to me. "Please don't make me leave, okay?"

Blood Demon Vampires are naturally born to be cold-blooded, ruthless, self-centered, and blood-sucking demons every time the sun goes down. Let's bring their kinds to a brand-new story, shall we? What if the vampires were befallen into a cursed system where killing is no longer a formidable solution for their thirst for blood? Instead of merciless killings, they are required to accomplish humanitarian missions in order to survive. One human saved is an hour additional of their lifeline in the human world. The more humans they saved, the longer life they get. Then were measured when this one-of-a-kind woman appeared in their lives. The only woman who awakens their dormant vampire's thirst for blood.

I had agreed to pay 10,000 at the wedding. At the very last minute, my mother-in-law, Alice Thompson, suddenly raised it to 500,000. I went to confront them. My husband, Dylan Forrest, kept his head down, pretending not to hear a thing as he looked at his phone. Alice rolled her eyes, clearly about to brush me off with some excuse. But instead, the truth spilled out of her mouth against her will. "Of course we have to take advantage of you being pregnant and unable to run to squeeze as much money as we can. It's the perfect timing to use it to buy Gideon a house, paid in full!" The words were like a silent explosion. I was so furious I actually laughed. "So, that's the plan? You're trying to strip me for everything I have? If I don't pay, does that mean there's no wedding?" Alice clamped a hand over her mouth, panic flashing across her face. But her voice came out louder than ever, like it was blasting through a speaker. "If you don't pay, then get lost! You're just a pregnant, used woman. Who else would want you besides Dylan?" The guests erupted instantly. Dylan's face went pale as paper. I smiled. Then a mechanical voice rang in my head. "Honest Lies System activated. Malicious fraud detected. Reward granted: 100 billion. Match assigned: the richest man in Lumeria at the next table." "Fine," I said softly. "You said it yourself." I wanted to see just how the Forrests planned to show their faces tomorrow after every ugly truth they'd tried to hide was dragged out into the open.
