- Description from MTLNovel

After being kicked out by her family, she turned out the real heiress worth billions, and people around her got to know it.Her family regretted deeply and demanded half of her fortune as repayment for bringing her up. She sneered and used a truth-telling talisman to expose their plots.A scumbag had always been pestering her and wanted to get back together. She easily made him “meet his ancestors” every night.Moreover, her cousins had looked down on her, regarding her as a disgrace.Surprisingly, the chairman of a rich family came to her and said, “As long as you can save my daughter, I'll meet all your demands!”Another rich family, who had been at feud with her new family for a long time, also shamelessly came over and said, “As long as you can help us, our family will be very grateful for the kindness of your family!”Later, even the rebellious cousin became her follower, claiming, “She is my only sister! Whoever dares to insult her, I will curse their entire family!”Her new family finally realized that their little poor girl was actually a big shot!“I need to draw spells, get rid of evils, save people and chase that guy! How busy I am!” She said in distress.That guy, “Actually, you don't need to chase me. I'm already yours.”

Way, way, and very way before I was even born, my world was invaded. Actually, not just my world, my entire damn universe was overrun by another, led by a single race that called themselves the Eternals.And they were prepared. Very prepared. Every life we lost in the war against them was used by them. They didn’t just kill people, they captured their souls, forged them into Phantoms, and used the souls to twist beasts into Abominations. Our dead became their army.Three hundred years later, I was born. A guy with way too much energy. Sitting still? Impossible. Taking it slow? Not happening. I was always moving, always ready to burst into action. Then I awakened, and got a talent too.My Talent's Name Was Generator.Because of it I never ran out of energy. Ever. My muscles? Supercharged. My healing? Faster. My stamina? Please, I had no idea what being tired even felt like.So if the universe wanted to throw an endless war at me?Fine. I’d throw everything I had right back.I wasn’t born a hero. Never wanted to be one. But this war? It wasn’t just my universe’s fight anymore. It was mine. The Eternals made sure of that when they took my parents' souls.

“I’m a warrior from the alternate universe.”“The Goddess summoned me to this world to defeat the Devil that has imperiled the world and to restore peace to the world.”“I understand that it’s my cardinal duty. Since I’ve been summoned to become a Warrior, I’ll do my best to beat my opponent even if he’s the almighty Devil.”“Don’t ask me why. That’s what the book says.”“But… isn’t this development straying from the plot?!”This is the beginning of a scam in an alternate universe. It is also the story of a warrior with a mission to defeat the Devil. At the end, he realized that he had been duped instead.
