This Billionaire Heiress Doesn’t Tolerate Anyone’s Nonsense

I was a retired powerhouse from the Transmigration Agency. My points had reached the maximum, so the system specially approved my vacation in a perfect world. I selected a world where I was the heiress to a billion-dollar fortune, blessed with extraordinary luck. My parents spoiled me endlessly, and my fiancé was the heir to a financial empire. I had the perfect life of a born winner. Just when I was admiring how comfortable retirement was. The system alarm suddenly blared. A glaring red warning box appeared before my eyes. [Attention, host! The world line has collapsed! The villain is about to enter the story!] [In ten minutes, your hypocritical aunt will take you to the private lake to feed the swans, then push you in!] [Your cousin will pretend to rescue you, move into your home, and steal everything from you!] [That isn’t all. She will seduce your fiancé and join forces with him to drive your parents to their deaths.] [In the end, you will be locked in a basement and abused by her every day.] I smiled. My retirement had finally stopped being boring. The next second, my aunt walked over with her daughter, holding her hand and beaming. "Oh, my sweet niece. Come on. Shall we go over there and feed the swans?" I immediately dropped onto the ground and grabbed a handful of mud mixed with dog feces. Then I smeared it all over her precious daughter’s limited-edition princess dress. I pointed at her and wailed at the top of my lungs: "Bad! Push! Water!" You want me dead? I’ll send your entire family to the grave first! Chapter 1 Mud mixed with grass clippings left a large, ugly stain on the limited-edition princess dress my six-year-old cousin, Maya Shaw, was wearing. The smile froze on Maya’s face. A second later, she pouted and burst into tears. “Waaah… My dress… Aaron gave it to me…” The warmth vanished from my aunt Mandy Rivers’ face, replaced by barely suppressed fury. She quickly composed herself, crouched down, and forced a smile as she reached for me. “Be a good girl, Yuna. Why are you sitting on the ground? Come on, get up. I will take you to change and wash your hands.” Her hand had not even touched the hem of my clothes. I immediately flailed and rolled across the grass, screaming at the top of my lungs. “No! Bad Auntie! She tried to push Yuna into the pond!” I pointed at the nearby pond with my chubby little hand while crying. A section of the wooden railing beside it was visibly broken. Mandy had damaged it in advance. Her face turned pale, and she hurried to cover my mouth. “What nonsense are you talking about?” “Waaah!” I cried even harder until my little face turned bright red. I gasped for breath as if I might faint at any moment. Right on cue, the floor-to-ceiling window on the mansion’s second floor burst open. My mother called out in a gentle but worried voice: “Yuna! What happened?” My father, Michael Rivers, rushed out of the house right after her. When he saw me rolling around on the ground, covered in mud, his face crumpled with heartache. “My precious darling! What happened?” He scooped me up and held me tightly, using his suit sleeve to wipe the mud and tears from my face. Mandy immediately put on a tearful expression. “Michael, this is all my fault. I saw Yuna playing by herself, so I wanted to take her to the pond to feed the swans. “Who would have thought she would trip and fall, then get Maya’s dress dirty…” Her eyes reddened as she spoke. “Yuna is still young and doesn’t know any better. Maybe she thought I pushed her, which was why she kept crying and wouldn’t let me touch her.” Maya sniffled as she tugged at my mother’s clothes. “Don’t blame Yuna, Auntie. It’s my fault. I shouldn’t have worn such a pretty dress outside…” What a pair of shameless little hypocrites. The mother was a master at playing innocent, and her daughter was no different. My mother looked at the stain on Maya’s dress, then at me, crying so hard I could barely catch my breath. Her brows knitted together. “Mandy, Yuna is still young. You’re her elder, so don’t hold it against her.” My father ignored them completely. His attention remained fixed on the direction I had pointed. He followed my finger and saw the loose section of railing beside the pond. His expression darkened instantly. “What happened to that railing?” Mandy stiffened and quickly explained, “It must have been damaged over time. I didn’t notice it earlier.” My father said nothing. He carried me toward the pond in large strides. He stretched out his foot and gave the railing a light kick. With a sharp crack, the entire section snapped off and fell into the water, sending up a splash. If Mandy had really taken me over there earlier, I would have been the one falling into the pond. My father’s face turned completely dark, and the air around him grew terrifyingly tense. He turned around and swept a cold glance over Mandy. “Someone seal off the pond! No one is allowed near it without my permission! “Also, find out who was responsible! Check the maintenance records for every facility in this mansion! “Find out who went near the pond over the past few days! If you can’t, all of you can get out!” Mandy’s face turned deathly pale. She could not utter a word. My father stopped looking at her, turned around with me in his arms, and walked away. “Come on. I will take you to have a bath and change your clothes. We won’t worry about those bad people.” I nestled against my father and looked back at Mandy, who stood frozen in place. Then I flashed her a wide grin. “You wanted me dead? Keep dreaming.” Chapter 2 That evening, the Rivers family held a small gathering at home. On the surface, it was a family gathering. In reality, it was a welcome party for Aaron Cooper, the Cooper family’s little heir and my future fiancé. Aaron was eight years old and looked like a little prince. He had a cold personality and always wore a stern expression, ignoring everyone around him. However, whenever he saw me, a trace of warmth softened his icy face. He carried an exquisite box over to me and opened it. Inside was a crystal music box carved with an elegant ballerina. It was a globally limited-edition collector’s item. “It’s for you.” His words were brief and to the point. Before I could reach for it, Maya’s eyes lit up beside me, and she gasped. “Wow! It’s Swan’s Dream! Mommy said this music box is so rare that even money can’t buy it!” She stared at me enviously, as if she wanted to pounce on me and snatch it away. I sneered inwardly but happily clapped my hands. “Pretty! I like it!” Aaron placed the music box on the table in front of me and said simply, “I’m glad you like it.” The adults chatted in the living room, while my mother asked me to take Aaron and Maya to my toy room. My toy room covered more than two thousand square feet and was packed with all kinds of toys. It was practically a miniature amusement park. The moment Maya entered, the toys dazzled her so much that her mouth fell open. She touched one toy, then hugged another. The greed in her eyes nearly spilled over. Aaron had no interest in my childish toys. He remained off to the side, silently watching me construct things with my blocks. A servant brought in snacks and fruit juice midway through our playtime. I was completely focused on building my castle when the system suddenly sounded an alarm. [Host, pay attention! The villain is stealing your gift!] I looked up and saw Maya sneakily stuffing the Swan’s Dream music box into her little crossbody bag. She then took out a cheap plastic music box and carefully placed it where the original had been. Afterward, she nervously glanced at Aaron and me. She only relaxed when she saw that neither of us noticed her. She patted her bag and smiled smugly. I lowered my head and continued building with my blocks, pretending that I had seen nothing. Not long afterward, Mandy walked in with a bright smile. “How are you children enjoying yourselves? Maya, don’t you love music boxes? “Come and look at your cousin’s. Isn’t it prettier than all the ones you have?” Mandy deliberately directed everyone’s attention to the music box, hoping I would mistake the cheap plastic one for Aaron’s gift. That way, everyone could laugh at me for treating a worthless toy like a priceless treasure. Maya cooperated immediately. She ran over, picked up the plastic music box, and exclaimed with fake excitement. “Wow, this music box is so pretty too! Yuna, do you want to trade?” Mandy covered her mouth as she giggled. “Maya, stop fooling around. That music box is a gift from Aaron. How could you ask her to trade it so casually?” I put down my blocks and slowly climbed to my feet. Under their smug gazes, I ignored the plastic toy and walked straight toward Maya. Maya instinctively took a step back and hurriedly shielded her bag. “W-What are you doing?” Without saying a word, I yanked her bag off her shoulder and pulled open the zipper. In front of everyone, I tipped out the crystal music box inside. “Mine!” I said in my childish voice, enunciating the word clearly. Then I grabbed the plastic music box from the floor and hurled it at Mandy’s feet with all my strength. The plastic casing shattered, releasing a harsh, grating noise. “She took mine! Bad!” The room fell silent. Mandy’s smile froze on her face. Her expression shifted rapidly from shock to panic to fury. Maya burst into tears with a loud wail. Aaron, who had not said a word until then, stood up. He stared coldly at the mother and daughter, his eyes filled with disgust. “The Rivers family’s upbringing is truly an eye-opener.” My mother hurried over when she heard the commotion. Her expression darkened when she saw the mess covering the floor. “What happened?” Aaron pointed at the crystal music box on the floor and the sobbing Maya. His answer was brief and direct. “She stole it.” My mother understood immediately. She glanced at Mandy, whose face had gone ashen, then called over the guards. “Search her.” Mandy still tried to argue. “Diana! She’s only a child. She doesn’t know any better. Maybe she just picked up the wrong one…” “Picked up the wrong one?” My mother let out a cold laugh. “Then why was the fake music box in her bag? She deliberately switched it with the real one.” The guards ignored Mandy and immediately searched Maya. Before long, they found a diamond bracelet in Maya’s pocket. It was the bracelet my mother had put on me earlier that day. She had been caught red-handed. Mandy’s face turned beet red. She had never expected her daughter to steal the music box and take something else while she was at it. This time, the evidence left Mandy with no way to excuse Maya’s actions as a simple mistake. My father walked over with a grim expression. He was so furious that he could not speak for a moment. “Mandy, this is the daughter you raised!” Mandy dropped to her knees, wrapped her arms around my father’s leg, and cried out. “Michael, I was wrong! I didn’t raise her properly! Please forgive us this once!” I watched her hypocritical performance and found it laughable. This little trick was only the opening act. The real game had just begun. Chapter 3 After being caught stealing, Mandy and Maya stayed out of trouble for a while. My mother was already in poor health, and she recently began feeling unwell. She often complained of fatigue. Mandy seized the opportunity and began visiting the Rivers family every day. She personally prepared all kinds of nourishing meals for my mother. She acted like the perfect homemaker in front of my parents, but whenever they were not looking, she glared at me with such hatred that she looked as if she wanted to kill me with her eyes. That day, Mandy came in carrying another bowl of steaming, dark-colored broth, a broad smile plastered across her face. “I had someone track down an old country remedy for you. It’s supposed to restore your health, so drink it while it’s still warm.” My mother accepted the bowl and was just about to take a sip when the system alarm blared again. [Warning! The broth contains a slow-acting poison! Prolonged consumption will cause nerve damage and organ failure!] My eyes widened. What a vicious woman. She actually wanted to poison my mother! I immediately slid off the sofa, hugged my little sippy cup, and staggered over to Mandy. “Auntie, drink milk.” I held up my sippy cup with an innocent expression. Mandy impatiently tried to push me away. “Go on, go play somewhere. Don’t get in the way of your mother taking her medicine.” I refused to leave. Instead, I hugged her leg and held my sippy cup beneath the bowl of soup, using it to block Mandy’s view. While she was distracted, I pulled the dog kibble from my pocket and poured it into the black broth. The kibble had been specially made. Its pieces were small and hard, so they quickly sank to the bottom. Once I was done, I pretended to trip. I lurched sideways and knocked against Mandy’s arm. The ceramic bowl slipped from her hand, crashed to the floor, and shattered into several pieces. The black broth, dog kibble, and broken ceramic scattered across the floor, releasing a strange, indescribable smell. “Oops!” Mandy shrieked and raised her hand to slap me across the face. “You little brat! What have you done?” Before her palm could land, a hand seized her wrist. My father had returned without anyone noticing. He stood behind Mandy with an ashen expression, his murderous gaze fixed on her. “What do you think you’re doing?” Mandy turned pale with fear and hurriedly withdrew her hand. The smile she forced onto her face looked utterly pathetic. “Michael, you’re… you’re back. I… I didn’t mean to. Yuna was just being too naughty…” I immediately hid behind my father’s leg, poked my little head out, and pointed at the mess on the floor as I complained. “It stinks! Doggy won’t eat!” My father looked down at the spilled soup, and his brows drew together even more tightly. He caught a strange smell. Beneath the broth’s herbal aroma was the unmistakable, meaty scent of dog kibble. He crouched down, picked up some of the residue, and sniffed it. His expression changed completely. “Mandy, this is what you gave my wife to drink?” Mandy panicked and began explaining incoherently. “N-No, Michael! It… It was the kitchen staff. They must have used the wrong ingredients! Yes! They must have mixed the dog food into the soup!” She hurriedly tried to pin the blame on the kitchen staff. My father let out a cold laugh and stood up. He did not believe a word she said. “Is that so?” He took out his phone and called the family doctor. “Dr. Watson, bring your equipment and come over immediately. Yes, right now! “Also, take the contents from the floor for testing.” After hanging up, he fixed Mandy with a cold stare. “Until we get the results, you’re not going anywhere.” The color drained from Mandy’s face, and her body swayed unsteadily. She knew she was finished. I leaned against my father’s leg and watched her terrified, desperate expression without feeling the slightest bit moved. This was only the interest. For everything she owed me and my parents, I would make her repay it a thousand, and even ten thousand, times over. Chapter 4 The test results were not ready yet, and Mandy paced restlessly around the Rivers family’s home. She knew she could not keep the poisoning a secret for much longer. Since she had already started down this path, she decided to act faster and eliminate me—the greatest obstacle in her way. She discovered that I was severely allergic to an extremely rare type of imported flower pollen. Even brief contact could cause anything from a rash covering my body to respiratory failure and death. At night, she secretly crept into my room. The system had already warned me about her plan, so I arranged for the nanny to put me to sleep in the guest room. Maya had recently become obsessed with the diamond music box in my room. She had tried to sneak in and steal it several times. That night, she saw me leave with the nanny and slipped into my room. She hugged the music box and happily sprawled across my bed. She even rolled around a couple of times, completely unaware that the sheets had been tampered with. The allergic reaction soon began. Maya started feeling itchy all over. Frightening red welts quickly spread across her face and neck, and her breathing became increasingly labored. “Mom… Mommy… help me…” She struggled to call for help, but only managed to produce faint whimpers. In the end, her eyes rolled back, and she passed out. Mandy waited outside for a long while. When she estimated that enough time had passed, she pretended to come tuck me in and pushed open the door. She expected to find me suffering through a painful death. Instead, the child lying on the bed with a face covered in welts and barely clinging to life was her own precious daughter. “Maya!” Her anguished scream shattered the quiet of the Rivers family’s mansion. My parents woke up and hurried over. They were stunned when they saw what had happened in the room. Mandy held the unconscious Maya in her arms and sobbed hysterically. The moment she saw my parents, she rushed toward them like a madwoman, pointed at me, and screamed. “It was her! Yuna did this to my Maya! “She knew Maya was allergic to pollen, so she deliberately scattered it across the bed! She wanted to kill my daughter!” She twisted the truth and accused me before anyone could blame her. “Michael, you and your wife need to see how vicious this child is! “She’s only two and a half years old, yet she’s already this cruel! She isn’t a normal child! “She’s a little psychopath! We have to send her away—to some kind of behavioral facility where they can discipline her! Otherwise, she’ll kill every one of us someday!” Tears streamed down her face as she spoke with such apparent sincerity that anyone would have thought I was an utterly irredeemable monster. My mother stared at the chaotic scene, looking completely at a loss. My father’s brows drew tightly together. He looked at me as I stood silent while Mandy pointed at me and berated me, a complicated emotion flashing across his eyes. Mandy saw his reaction and cried even harder, convinced that her scheme had succeeded. “Michael, you can’t keep going easy on her! For the sake of our family and everyone’s safety, you have to send her away!” Just as she thought victory was within her grasp, I suddenly stopped crying. I had been trembling in the nanny’s arms until then. I calmly took a miniature camera disguised as a rubber-duck toy from my pocket and pointed it at Mandy. My voice still sounded childish, but every word rang out clearly through the room. “Auntie, look at this. Isn’t it fun?” A beam of light shot from the rubber duck’s eye and projected onto the white wall opposite us. The high-definition footage clearly showed Mandy sneaking into my room. She sprinkled a packet of white powder evenly across my bed… The entire room fell into stunned silence.
