- Description from novelbuddy

In 2030, humanity faced its first true collapse…not by war, but by the sudden invasion of Nightcrawlers, creatures emerging from darkness itself with the desire to devour sunlight at all cost for their evolution.But, they could not absorb it directly since it was as deadly to them as to a shadow under the noonday sun. They could only absorb the sunlight from lifeforms or through signing a nocturnal contract to possess their bodies, providing them with direct sunlight immunity.Within twelve hours, over four billion people perished as Earth was split between eternal night and day.Just as extinction loomed, Holy Light Pillars descended from the heavens, purging one thousand cities from Nightcrawlers and offering humanity sanctuary under their divine light.A century later, in the Heliodor Region, an innocent child found his world turned upside down after two mysterious nightcrawlers invaded his home, slaughtered his parents, and ripped his eyes out of their sockets, leaving him permanently connected to the Shadow Dimension, the home ground of Nightcrawlers.Was it just a random feeding session for them, a planned assassination, or it goes deeper than this?Follow Levi’s journey as he weaves between darkness and light, chasing the truth hidden in both.

Collapsed without warning, and upon awakening, he found himself back in his childhood.He thought it was a blessing from above, but unexpectedly, tumultuous changes ensued, shrouded in mystery...

{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.**
