{System Online} {System Activating} {System Activation Complete.} {User Detected: Jake Lucas.} * {Main Quest: Grow strong enough to defeat your foes.} *{Warning: Darkness Approaches. No One Is Safe.}* 200 years ago, humanity almost faced extinction at the hands of the werewolves. The world survived, but the cost was unimaginable. Victory was hard-earned—and the price paid is still unknown. After seeing the war wasn’t heading anywhere, the werewolves receded to grow their strength while letting the humans recover. Now, sixteen-year-old Jake Lucas is thrust into a battle he never wanted. Weak, outcast, and haunted by his parents’ brutal deaths, Jake is just trying to survive at Aurora Academy. But when a strange orb activates the Slayer System, everything changes. Quests, skills, and powers that could make him stronger than he ever dreamed. But power comes with a price. With each new level, Jake uncovers dark secrets—about the werewolves, the academy, and the shadows lurking beneath them all. The world is more dangerous than he imagined, and a hidden force is stirring, ready to rise once again. Jake’s only hope lies in mastering the Slayer System—but as the stakes grow higher, he’ll learn the real question isn’t how strong he can become, but *how far he’s willing to go* to stop an ancient evil from being unleashed. **But the system has a final warning: Jake isn’t the only one unlocking power. And the clock is ticking.**

What is my 1000-year-old monster self to do when I’ve failed my immortal ascension? Time travel — accidentally — and wind up back in my 9-year-old body, needing to re-cultivate, of course. But after that? Get REVENGE! Muahahahaha! But the idiot who killed me — also accidentally — was the main character of the dumb harem Xianxia I transmigrated into. But wait. Wasn’t he only 7 or 8 at this point in time? Well, since I can’t harm a child or the main character without suffering in some way, then I’ll just have to raise him better, faster, stronger, and loyal! Muahahahaha!
