Who Is The Strongest Antagonist In 'My 100 Cheat Codes System'?

It was the tenth year of the Mechanical Civilization. My girlfriend, who always spoiled her brother to an unreasonable extent, orchestrated my death. Luckily, I was reborn seven days before the arrival of the machines. I bought a heavy-duty truck and evolved the strongest mecha. Close-combat mecha, long-range mecha, weapons, shields, funnels, modules… This time, I wanted the best of everything. My name is Victor Wild. Born to be a victor, born to be wild.

When the apocalypse came, she lost everything. Starving, hunted, and desperate, she trusted the one man she loved… only for him to betray her in the cruelest way possible. He stole her last supplies to please another woman and left her to die in a sea of the undead. But death wasn’t the end. She woke up days before the world collapsed. After cutting ties with her ungrateful ex and his parasitic family, a mysterious voice awakens in her mind, LUS, a Level-Up System designed to help her survive the coming end. With knowledge of the future and a system guiding her every move, she begins to prepare. She stockpiles resources, builds a base, and learns how to fight back against the horrors that once destroyed her. And when the apocalypse arrives again… she’s ready. But survival isn’t the only thing waiting for her in this new life. A silent killer who watches her like prey. A manipulative genius who wants to unravel her secrets. A gentle protector who sees the girl she hides. And a dangerous man who thrives in chaos. As the world burns and power shifts, they’re all drawn to her, each with their own motives, each with their own darkness. Even her past refuses to stay buried. Because now, the man who once abandoned her is back, broken, desperate, and begging for a second chance. Too bad she has no time for regrets. Not when she’s busy rising to power… and building a kingdom in the ruins of the world.

In a world with machines and angels, the main character has to become the strongest to avoid getting killed and discarded.

He was supposed to be nobody. Born with crippled spiritual roots in the weakest corner of the Mortal Heaven Continent, he spent his early years mocked by peers, dismissed by elders, and written off as a waste of a bloodline. The world had a plan for people like him — obscurity, mediocrity, a quiet death at the bottom of the cultivation ladder. Then the System arrived. Rude, chaotic, and absolutely unhinged, the Infinite Chaos System begins issuing missions so absurd they border on cosmic comedy — slap an arrogant Young Master, steal from a forbidden ruin, insult a Heavenly Lord to his face. And somehow, at the end of every ridiculous task, he walks away stronger than before. What begins as a shameless scramble for survival slowly reveals something far more terrifying. His talent isn't crippled. It was sealed. His bloodline isn't ordinary. It was buried. And the System that appears to be helping him? It was never designed to help anyone. As he rises from a forgotten boy in a forgotten kingdom to a figure that shakes the foundations of all Nine Realms — and the ancient dimensions lurking beyond them — the truth peels back in layers. The history of the cosmos is a lie. The gods who rule from their thrones are terrified. The first user of his System already conquered everything and nearly destroyed it all. And somewhere at the end of every road, a question waits: what do you do when you've beaten every enemy, unraveled every secret, and the universe itself asks you to become its next ruler? He laughs, pockets another ancient treasure, and causes more problems.

"Get on your knees." "Bend over." "That's it... take all of me, sis.". Stealing a bestselling novel was supposed to be a harmless crime. Dying before I could read it wasn't part of the plan. When I opened my eyes, I had become the story's most hated villainess—trapped in a brutal world ruled by beastmen, where my terrifying stepbrothers were destined to destroy me. My only lifeline? A shameless System that throws me impossible missions, ridiculous tasks, and forces me closer to the very men who want me dead. In a world where trust is a luxury and death lurks around every corner, can I rewrite my fate... or will I become the villainess everyone wants to see die?

After the SAT scores get released, everyone in the advanced class hits the 1,400 threshold. The campus heartthrob, Luke Gilbert, recommends the latest AI college application app that is developed by his dad's company to make it easier for everyone. I pull Keyla Simmons, the class president, over and warn her that the risks that come with using an AI application app are far too high. On top of that, there are deadly flaws within the app that can lead to the students getting rejected by their dream colleges. But Keyla responds by hurling a high heel in my face. All of my classmates surround me and begin mocking me relentlessly. "Justin, you're just worried that everyone will get into better courses once they used the AI app to apply for their colleges!" "Heh! If you have a crush on Keyla, then just say it out loud! There's no need to play the jealousy card and throw a tantrum just to ruin everyone's future! Besides, look at how haggard you are right now! You can barely hold a candle to Luke, our campus heartthrob! Haha!" I'm so pissed that my asthma attack gets triggered on the spot. For the sake of everyone's future, I can only escalate things to the point that the education department gets involved. Only then can I stop everyone from using the app. Unexpectedly, on the day I receive my college acceptance letter, a bunch of convicts, who have escaped from prison, vandalize the bookstore that my family owns. Those bastards even violate me and my younger brother in front of our parents. At the same time, they keep gushing about how doing it with a guy feels way more satisfying. Then, they kill our parents in cold blood right in front of our eyes. In the end, they set the entire bookstore on fire, ultimately burning us into ashes. What's worse is that this terrible incident doesn't get reported at all. Instead, my classmates slander me for having illicit relations with outsiders when I was still a high schooler. When I open my eyes again, I've returned to the day Luke suggests that everyone use the AI college application app. This time, I don't bother stopping them. Instead, I'm the first one to agree with Luke. "Humans have to adapt to the growing trends. AI is definitely more professional than humans."
