My Multisystem In Isekai

My girlfriend betrayed me for a rich man, mocking me as worthless trash. Beaten down and humiliated, I thought my life was over, until a stranger called to say I was the heir of the world’s most powerful family. My pocket money? A card with 100 million inside. I thought it was a scam… until I checked the balance. It was real. That same voice called again: he was my butler. The family had already chosen seven stunning fiancées for me, and if I wanted the full inheritance, I had to marry them all. From abandoned loser to billionaire heir with seven breathtaking brides-to-be… and just when my wedding banquet lit up the city, my ex came crawling back. I only spared her a glance, then turned away forever.

My girlfriend left me for a richer man. My boss treated me like dirt because I had no money. Then the Infinite Cashback System activated. From now on, the more I spend, the more I earn. Buy an ordinary suit, and the system rewards me with a luxury fashion brand. Treat someone to dinner, and a five-star hotel becomes mine. Now my four children are spending their holiday with me, and every dollar I spend spoiling them returns to me a hundredfold. My ex and my boss called me to an office meeting to humiliate me and show off their new status. I'm about to walk in as the richest man they've ever seen. Yesterday, I could barely pay my bills. Today, even billionaires seem poor beside me. And the system has only just begun.

When the media exposed that I was the true heir, they dragged me back from the countryside—not to welcome me, but to shut me up. My mother called me an embarrassment. My three sisters begged my father to keep the fake brother instead. My ex-girlfriend? She laughed and said, "He's everything you'll never be." They don't know that the real heir died years ago. I'm just a transmigrator who woke up in his body and I've already read the novel about this family's downfall. I know the fake brother is planning to bankrupt my father. I know the lottery jackpot he's about to win. I even know the exact moment my mother will kneel and cry for my forgiveness. They want a scapegoat? Fine. I'll play the fool. But by the time they realize I'm not the victim, I'll own everything they love.

I struggled on my feet. But my weakness brought me against the ground. He brought out his Claus and shoved it in my rib, making blood gushed out my mouth. I screamed in terror and pain,realizing there was no escape to death. giving up now doesn't mean you are weak sometimes is better to let it go. But my killer shall reap what he sole, which is death. ***** A reincarnated priestess who was killed by a demon in her past life, led her life as a normal girl in the city. But after she remembered the long forgotten memories of her past, she took a dangerous step ahead. But how did she became a Mate to a Demon who was said to be a legend, a man who hated her very existence.

My name is Zane, and I am just a poor boy from the Mainland slums. To keep my little sister, Kemi, alive, I trusted the richest magic guild in the city. I thought they were going to cure her sickness. Instead, they used me. They strapped my sister to a machine to tear a legendary power source called the Calamity Core straight out of her chest. When I tried to save her, they broke my bones and left me to die on a freezing hospital floor. But I didn't die. A blue digital screen popped up in front of my eyes, granting me a forbidden power: sovereign necromancy. Now, every monster I kill and every corrupt billionaire I crush must stand up and join my shadow army. The rich think they own this city behind their high concrete walls. But I am coming for them with an army of the dead, and I will make every single elite bleed for what they did to my family.

'Waah......waaah' My baby was crying tremendously and here I was thinking what was happening there. "It's ok child .Everything is going to be alright, The bitter seeds that I have sowed .I would not let you cut them in my instead ,that's my promise to you" Suddenly the horse slipped and I fell to the ground with my child intact. I mumble to myself "Is this what we call karma but still I must protect you .I Immediately left the horse and tearing the magic scroll .I whispered 'The Catholic Temple' "Bring that child to me," said Patricia, the Highest priest in rank. As he holds my child with care in both hands a question arises in his mind "What name do you like to give him? He is your son. It's wise if you give him a name." . I took a last glimpse afterwards,I turned my back against him before murmuring with an uneven heart."I always desire to call him Ryaniar ." I have been running Goddess. I have been running a lot from my destiny till my sister to the handmaiden. Everybody has been sacrificed against my bad fortune .It even did not let the white witch unstained. So how come I dared to fantasise a future that's very bricks was served by uncountable baits. If you are reading this letter then . At least I can entrust his safety to you. Please save my child in this life. Your deceased Isabella Facebook: https://m.facebook.com/ Instagram: https://www.instagram.com/mint_malimilkain10001/

My name is Tobe, and I am just a poor boy from the Mainland slums. In our city, a massive concrete wall separates the poor people from the rich elites who live on the Island. The rich have everything: wealth, high-tech weapons, and powerful magic guilds. We have nothing but dirt and rifts, dangerous tears in reality that let monsters crawl into our streets. To keep my fourteen-year-old sister, Amarachi, safe, I worked myself to the bone. But the Island elites do not care about people like us. They tricked me. They used my family, took our blood, and left us to die so they could unlock a dark, legendary power called the Calamity Core. But I did not die. Instead, I woke up with a blue digital screen floating in front of my eyes. The system gave me a unique power that no other hunter has: Sovereign Necromancy. With every monster I kill, and with every corrupt elite I strike down, I can command their souls to stand up and fight for me. Every shadow I touch becomes my loyal soldier. Now, the rich elites are hunting us down to steal the core inside my sister's chest. But Amarachi is not a helpless child anymore, and I am no longer a weak boy from the slums. With an army of shadows at my back, I am breaking through their walls. I will protect my sister, destroy their corrupt guilds, and make every single billionaire pay for what they did to us.

This is a story of betrayal, revenge and most of all, mystery. For the longest time, all I've ever known was... Darkness. I was born and brought up in a family of royals, in a world of thorns and scorn, hate and greed, lies and betrayal, selfishness and parasitism. It wasn't easy surviving on my own but I found my way, in the shadows where I belonged. Many would envy and seek out my lifestyle because it appeared luxurious, and glorious even but it really wasn't. I was trapped in a neverending fight for control and most of all, my life only to see my death encroach slowly, to the point I started having nightmares about it. I was even abandoned by my own father. Well... It didn't matter. Because at the end of the day, I survive in between the light and darkness. I survive... In the shadows.

Anger, hatred, sorrow, grief, despair. Who would have thought that my happy-go-lucky life would turn out like this within a day? My parents, dead. My family abandoned me. The world ostracized and treaded over me. The Goddess- cold, strong, and against me. And finally, my weak self, the only potential-less in the world of overwhelming Potential-bearers. Just one step and everything would be over... or so I thought. My Discord ID- Elixer_Yuu#5328 The credit for the cover goes to... I don't know who it is.

I will not let them go, this burning grudge must be completely vented, their destruction is the goal of my life.
