“You don’t need divine blood to burn the world down. A mortal’s flame does the job just fine.” Meet Minato. He was the last surviving master of an ancient clan known for its deadly martial arts and weapon-making skills. Now? He’s just a guy who woke up in the blood-soaked, cannibalistic streets of the Tokyo Ghoul universe. No magic. No overpowered cheat system. No bullshit bloodlines. Just his bare hands, lethal tech, and pure human grit. But when he crosses paths with a certain one-eyed girl named Sen Takatsuki (Eto), the rules of the game change. In a city crawling with flesh-eating monsters, Minato is going to show them exactly why humans are the real apex predators. He’s going to bathe in the sins of this broken world and violently carve out his own throne. But Tokyo is just the warmup... Minato is on a one-way warpath across the multiverse to prove a point: Gods can bleed, and he's the guy holding the knife.

Hello everyone, I was reading a few cross over comics that included Batman and Spiderman crossover to Captain America and Transformers crossover to fanfics that included Pokemon and Transformers crossovers. It looked like fun so I decided to write this while I am having a bit of writers block. BTW this will be like a short novel, less than 30 chapters. It will not be a full fledged book. If anyone wants to make these ideas full on books go ahead. Just give me a heads up because I would love to read them too. :D

[Irresistible MC + Farming & Entrepreneurship + Strong Female Lead + Cute Baby + Love Rivalry + Farming System + Male Competition] Deng Yuyuan wakes up to find she has transmigrated into a period novel about a "pampered group darling" — as the biological mother of the vicious female villain. The female villain has a biased grandmother, a mooching uncle and his family, a blindly filial father, and a spineless mother. She was a small-time thief as a child. As an adult, she committed every kind of evil — constantly framing the female lead — and ultimately met a miserable end. The female lead is the only daughter in another family, doted on by her older brothers. The villain targeted her out of pure jealousy. And now, Deng Yuyuan has become that villain's cowardly mother — and the villain herself is currently just an ugly, wrinkly-faced infant. The blindly filial father loves his wife, but gives all the good things to his own mother. He says to his starving wife and daughter: "Xiao Yuan, come drink some water. I specially heated it for you." Deng Yuyuan looks at her own bony frame and her tiny child — and decides to get a divorce. Goodbye, useless husband. She's going to raise this little cub with an abundance of money and love. No way she'll go astray this time. Lost one husband, gained a crowd of suitors. A beautiful sent-down youth coveted by many — she knows some self-defense and burns the midnight oil studying. With the reinstatement of the college entrance exams, she takes her child toward a much wider world. Riding the wave of the times, Deng Yuyuan works her way up to become a gaming tycoon and a cutting-edge scientist... Except — why are so many men fighting to be her cub's stepfather?
