The global freeze descended, and the apocalypse arrived right on cue. I seized all the critical supplies and evacuated first, leaving "the perfect base" behind for the two traitors who backstabbed me. They thought it was heaven, but little did they know that the entire fortress was a precision trap constructed of deception, scarcity, and despair. As the outdoor temperature plummeted to minus eighty degrees, I sat by the window, roasting venison and watching them through high-definition infrared, coldly observing as they lost their humanity in the desperate fight for a single bowl of sawdust.

In my last life, my parents favored my younger brother. They promised him to the angel who would remain on the surface, and shoved me to an abyssal demon.
When the apocalypse came, the angel burned through her divine power and fell. I took my family in out of kindness, and they repaid me with a bowl of poisoned soup.
When I opened my eyes again, our whole family had reincarnated.
This time, my parents couldn’t wait to push my brother into the demon’s arms, dreaming of living off him inside the abyssal lair.
I watched them sign the shadow contract like they were grabbing a priceless treasure, then took the rejected holy-light angel without hesitation.
They had no idea the Abyss’s shelter is paid for in flesh and blood.
But an angel’s loyalty can raise an iron divine kingdom that never falls, even in this world-ending flood.

In my previous life, my wife was addicted to black market gambling on football, which caused us to lose everything.

After being reborn, she planned to run off with all the money, then dump me and elope with her lover.
What she didn't know was that I had awakened the ability to read minds and knew all her plans.

In my past life, I personally dug up two alien meteorites, handing the blue one that granted "Frost Mastery" to my childhood friend, Mike. He repaid me by sealing me inside an ice wall, cursing me to "die like a piece of trash" in the minus 70-degree blizzard.
When I opened my eyes again, I was back at the initial blast site.
This time, I didn't even spare him a glance; I stuffed both meteorites into my pocket.
I transformed a missile silo into a doomsday bunker, brought my parents inside, and stockpiled ten years' worth of supplies.
When Mike arrived with a gang of thugs to smash my door down, I stood in the warm command center, watching half his face rot with frostbite on the monitor.
I didn't open the door.
This time, I am sending back the despair of my past life tenfold.

When he returned, he found that his own brother had already passed away, leaving only a tombstone behind. His sister-in-law even planned to marry someone else and divide their brother's inheritance.

Yet beneath his feet, the Chicago underworld remained oblivious, unaware that their doom had already arrived.

Jack left home at the age of sixteen and spent many years wandering in places where corpses lay in abundance, using killing to end killing. Now, he has become the commander-in-chief of the three armed forces, a legendary general, and is also known in the military circles as the "Son of War", unrivaled in the world.
But just as he returned triumphantly, he discovered that his adoptive father, who had given him immense kindness, had passed away. Upon investigation, Jack uncovered a web of intricate conspiracies lurking behind the scenes.

After a one-night stand, she gave birth to a daughter for Alex.
Alex thought it was just a drunken folly, believing that she would later meet someone better, marry a clean and upright man, and have a complete family. Little did he know that she would raise her daughter alone.
"Daddy, Daddy, where are you?"
The little girl cried with a heart-wrenching agony, huddled in the corner and trembling helplessly.
Alex returned furious, and he made those who wanted to bully his wife and daughter pay the price!

My uncle and aunt told me that I couldn't become a wizard.

When others had received their admission letters to the Academy of Magic, I still had nothing. I was destined to become a mortal. But at this moment, an old wizard appeared in the relics left by my parents.

He was the most evil dark wizard two hundred years ago.

He was defeated in the Second Wizarding World War.

However, now his soul has been fragmented into countless pieces. If I help him resurrect, he guarantees that after he regains control of the wizard world, he will make me the president of the Magic Association and also let me become the president of the United States.

-- All of the above are false.

Actually, I'm just a pitiful person who had my magic sucked dry by an evil dark wizard. I have to bring the dark wizard along to study at the Academy of Magic, and I can't let anyone find out.

Agatha Arionsa Elara thought that her body was the only thing her adoptive family sold to pay off their gambling debts. She was sold to Xavier Calestiano Valois, a handsome billionaire and underworld ruler nicknamed the “Devil” for his cruelty.
Agatha planned to play her role as an obedient doll while secretly carrying out her mission as The Rose, an assassin searching for traces of her biological parents. She intended to kill Xavier once her goal was achieved.
However, Agatha was dead wrong. Xavier did not just buy a compliant girl. The man had known about Agatha’s double identity from the very beginning.
Instead of exposing her, Xavier used that secret to bind Agatha to his bed.
Xavier offered a deal she could not refuse. He would provide information about Agatha’s biological parents, but the payment was not money. It was Agatha’s body and complete submission as his wife.
Trapped in a passionate and manipulative marriage, Agatha had to fight against her ego that refused to submit, and her own heart that began to betray her when the Devil’s touch felt more intoxicating than freedom.
When Agatha realized that Xavier never intended to let her go, it was already too late. She was no longer just a contract wife, but had turned into an obsession locked in a golden cage.
