In a world where the gods gift a chosen few with great powers, Sam Shepard could be counted among the weakest of the weak. His crappy healing ability can’t even cure minor injuries without having to drain Sam’s own life force to do it. Hero society doesn't think Sam's useful, and after failing to heal those he was tasked to save, Sam couldn't help but agree. But it turns out that giving up the hero's life isn’t easy. Not when one’s caught in the machinations of the gods themselves.

After Sam gets pulled into rescuing the hero Thunder, he inherits a strange ability from her: the training system that taught Thunder how to become a top hero. Triple-A apparently holds the secret to leveling up one's power, a feat previously thought to be impossible. Not that it'll be easy to achieve...

A series of challenging missions and the occasional hero lesson from the system’s creator guarantee a lot of cuts and bruises in Sam's immediate future. But at least he finally gets the chance to go from zero to hero. Oh, yeah, there are also ghastly horrors and megalomaniac supervillains to contend with on Sam’s path to becoming the symbol of hope that humanity needs.

At 2:13 a.m., London died.
Not with explosions. Not with war. But with a message.
Every screen across the United Kingdom from the underground stations of Westminster to the rain-soaked alleys of Whitechapel suddenly goes black before a single sentence appears across the sky.
WELCOME, PLAYERS.
Within minutes, reality collapses into a living nightmare.
Monsters emerge from subway tunnels beneath King’s Cross. Entire streets vanish behind crimson fog. People awaken strange classes, levels, and abilities as the city transforms into a brutal game ruled by an unseen System obsessed with survival, evolution, and entertainment.
Those who level up live.Those who fail are erased.
Twenty-three-year-old Anderson Jones was nobody before the fall just another exhausted courier surviving paycheck to paycheck in East London while drowning in debt, family pressure, and a future that never arrived. But when the System awakens inside him, something goes terribly wrong.
CLASS ASSIGNED: LEVEL ZERO.
No combat skills. No stats. No future potential A dead class.
Abandoned during London’s first massacre and hunted by creatures far beyond human understanding, Anderson discovers hidden cracks inside the System itself strange errors, forbidden quests, and impossible rewards connected to a secret the game is desperately trying to bury.
But the deeper he climbs, the more horrifying the truth becomes.
The towers rising across London were never meant to save humanity.
They were built to select what survives after it ends.
Now Anderson must navigate collapsing factions, traitorous survivors, deadly floor trials, and a System that watches every choice he makes. Because somewhere inside the game, someone is manipulating the rules.
And they already know his name.
In a city where trust gets people killed and every victory unlocks something worse, Anderson will have to become stronger than the game itself or lose everyone he has left.

She was once a top-tier assassin—until she was betrayed by her own people and left to die.

But when she opens her eyes again, she’s no longer who she used to be. She’s become an ordinary high school girl—plain, overlooked, and the butt of everyone’s jokes.

Overweight. Bottom of the class. Abused by her stepmother. Framed by her younger brother. Mocked by teachers and students alike. Maybe the original owner of this body could endure it all—but she couldn’t.

They call her ugly? She’ll shed the weight, sculpt her body, and stun everyone into silence.
They call her stupid? Elite university presidents will fight to recruit her.
Top hackers will beg to learn her secrets.
Global financial tycoons will compete for her partnership.

This time, all she wants… is a quiet, ordinary life.

Yet as her true identity is revealed piece by piece, she rises—effortlessly—back to the very top of the world.

On the morning before Christmas Eve, I was polishing my shoes in my apartment, preparing to meet my girlfriend Camilla's parents, who lived in the uptown, the next day to discuss marriage.
Through years of hard work, I finally bought a house in the city.
I suddenly had a splitting headache, and a blue system interface appeared on my retina, telling me that the sea level would rise by 8,000 meters in 24 hours and that a deep-sea mutated tide would submerge the world.
To survive, I must get 10 people to each transfer $ 5,000 to me before the countdown ends , and I will receive an asylum spot for each transfer I receive.

In my last life, I risked everything to protect my fiancée, only for her to shove me into a horde of zombies with nothing but, "You owed David this."
When I got a second chance, I found myself back right before the rescue chopper took off at the start of the apocalypse.
As I watched her cling to the cabin door, refusing to leave because she was waiting for her ex, I stepped back without hesitation: respect, best wishes, stay together forever. This time, I'm done being the pathetic simp who gets played for a fool.
I snatched the top-tier crystal core first, awakened an apocalyptic-level power, and watched with a cold smile as the cheating couple turned on each other in the middle of a pile of corpses, stabbing and screaming in despair. When the end of the world comes, you deal with the bleeding hearts first—then you rise to godhood.

The system told me to do good deeds during the apocalypse.
It also said I should redeem the world with love.
I’ve always been quick to take advice. So I raised my blade and struck down every scum of humanity one by one.
The system went berserk, letting out a shrill roar inside my head:
"Ahhh Host! Why are you killing people?! This is wicked! You’ll get your points deducted!"
I flicked the blood off my blade and looked around at the beheaded zombies littering the ground.
There was also the man I’d run through the throat—he’d just pushed a living person out to be eaten by zombies.
My fingertips brushed the word carved into the hilt: Love.
"What’s the problem?" I asked.
"I’m using my love to send them to where they deserve to go. Physical deliverance is also an act of kindness."
