Sin System: I Transmigrated Into The Villain’s Body
Princess MUD · Ongoing · 45.9k Words
Introduction
The empire remembers him as the cruel noble destined for execution. But now, a struggling writer has awakened in his body and the rules have changed.
[Sin System Activated.]
To survive, Lu Chen must feed on the envy, greed, lust, wrath, pride, sloth, and gluttony of those around him. Every sinful desire they feel fuels his power. But if he dares to be good… the system punishes him.
Now, Lu Chen doesn’t just play the villain he reinvents it. He manipulates, deceives, and dominates, turning the empire into a web of ambition and fear. Allies, enemies, even the heroine no one is safe from his calculated games.
Power is addictive, but Lucian is learning a terrifying truth: the system didn’t choose him to survive. It chose him to become the ultimate monster.
How far will he go when the villain refuses to die?
Chapter 1
"Lu Chen deserved a slower death."
Lucian Walter muttered the words as he scrolled through the final chapter of The Empire's Fall. His eyes burned from eight hours of staring at the monitor, and the empty caffeine pills on his desk offered no comfort. On the screen, the villain of the story a man with his same first name was currently being beheaded by the Holy Hero.
"He had the wealth of a kingdom and the magic of a progenitor, yet he used it all to harass a girl? What a waste," Lucian hissed, leaning back until his cheap office chair groaned.
His own reflection in the darkened window was pathetic. He was a failed writer with messy hair, living in a room that smelled like rotten ramen and stew. He looked back at the novel's comment section.
User449: Lu Chen was such a coward. Glad he's gone.
"If I had his power," Lucien whispered, his eyelids growing heavy, "I would have turned that empire into a playground. I wouldn't have died like a dog."
he grumbled, pushing himself up from his desk.
He walked over to the small, humming fridge to take water only to see that it was empty. In the center of the room, a plastic bucket sat beneath a steady drip, drip, drip from the ceiling. He looked at the water collecting in the bottom and let out a dry, mirthless laugh.
"At least I get free water without paying."
He aimed a half-hearted kick at a stray beer can that had been rolling around the floor since his neighbor's birthday party three weeks ago. It clattered into the corner. He collapsed onto his bed, staring up at the water-stained ceiling while the rain outside intensified, turning the sky into a bruised purple. Lightning flashed, casting sharp, jagged white light across his peeling wallpaper.
"When will all this be over?"
He turned to face the wall, clutching his stomach. The loud, hollow growl of hunger was the only sound that could compete with the storm. His eyelids felt like lead. He blinked once, then twice, and as the thunder shook the glass in the window frames, he finally drifted off.
KRA-AAAAA.
A violent crack of thunder jolted him upright. His heart hammered against his ribs.
"Oh, it's just the weather," he whispered, his voice thick with sleep. "I thought it was my stomach."
He moved to lay back down, but the surface beneath him felt different. It wasn't the thin, lumpy mattress he'd grown used to. It was soft impossibly soft.
"Young master Lu, young master Lu."
A hand was on his shoulder, shaking him with persistent urgency. He groaned, swatting the hand away without opening his eyes.
"Lu? Since when did my name change from Lucien to Lu? What type of dream is this?"
"Young master Lu, have you forgotten to attend to the guest who has been waiting for you since rooster hour?" The voice grew louder, more insistent. "The lady from the Yan family has been waiting while on her knees."
"What's all this noise about?"
Lucien snapped his eyes open and sat up. Instead of his water-damaged ceiling, he saw high, vaulted beams of dark wood. Standing over him was a bald man with a strange tuft of hair right in the middle of his scalp. He looked like a Shifu character straight out of a martial arts film.
"Who the fuck are you and what are you doing in my room?"
Lucien scrambled back, pulling his legs to his chest and cocking a fist, ready to swing.
The old man blinked, looking entirely baffled. "Fuck? What does that mean? I only came here to remind you, young master Lu Chen."
The man immediately bowed his head low.
Lucien froze. "Lu Chen? That's the character from my book. Why am I being addressed as that? And why is this man here? Why is"

The Alpha King's Human Mate
“I have waited nine years for you. That’s nearly a decade since I’ve felt this emptiness inside me. Part of me began to wonder if you didn’t exist or you’d already died. And then I found you, right inside my own home.”
He used one of his hands to stroke my cheek and tingles erupted everywhere.
“I’ve spent enough time without you and I will not let anything else keep us apart. Not other wolves, not my drunken father who’s barely holding himself together the past twenty years, not your family – and not even you.”
Clark Bellevue has spent her entire life as the only human in the wolf pack - literally. Eighteen years ago, Clark was the accidental result of a brief affair between one of the most powerful Alphas in the world and a human woman. Despite living with her father and her werewolf half-siblings, Clark has never felt like she really belonged in the werewolf world. But right as Clark plans to leave the werewolf world behind for good, her life gets flipped upside down by her mate: the next Alpha King, Griffin Bardot. Griffin has been waiting years for the chance to meet his mate, and he's not about to let her go anytime soon. It doesn't matter how far Clark tries to run from her destiny or her mate - Griffin intends to keep her, no matter what he has to do or who stands in his way.
Pregnant by My Husband's Rival Alpha
Those words should have destroyed me, but the truth was worse: I'd been used as a broodmare by the man who swore to love me, set up in a hotel room with a stranger because My husband Alexander Cross couldn't father children himself, and now I carried the secret babies of Damon Lester—the most powerful and dangerous Alpha in San Loris—while my own family replaced me with the daughter they'd always wanted. But when that same stranger's doctor appeared at my door, when twenty million dollars exchanged hands over a fake perfume bearing my secret identity, and when Damon's gray eyes locked onto mine with recognition I couldn't afford, I realized my carefully hidden life as the legendary perfumer Vera was colliding with a pregnancy that could cost me everything.
Could I protect my babies from the husband plotting my death, hide my true identity from the Alpha who's been hunting me for years, and reclaim the freedom I'd buried along with my dreams—even if it means standing alone against the wolves who see me as nothing more than a womb to be used and discarded?
After One Night with the Alpha
I thought I was waiting for love. Instead, I got fucked by a beast.
My world was supposed to bloom at the Moonshade Bay Full Moon Festival—champagne buzzing in my veins, a hotel room booked for Jason and me to finally cross that line after two years. I’d slipped into lacy lingerie, left the door unlocked, and lay on the bed, heart pounding with nervous excitement.
But the man who climbed into my bed wasn’t Jason.
In the pitch-black room, drowned in a heady, spicy scent that made my head spin, I felt hands—urgent, scorching—searing my skin. His thick, pulsing cock pressed against my dripping cunt, and before I could gasp, he thrust hard, tearing through my innocence with ruthless force. Pain burned, my walls clenching as I clawed at his iron shoulders, stifling sobs. Wet, slick sounds echoed with every brutal stroke, his body unrelenting until he shuddered, spilling hot and deep inside me.
"That was amazing, Jason," I managed to say.
"Who the fuck is Jason?"
My blood turned to ice. Light slashed across his face—Brad Rayne, Alpha of Moonshade Pack, a werewolf, not my boyfriend. Horror choked me as I realized what I’d done.
I ran away for my life!
But weeks later, I woke up pregnant with his heir!
They say my heterochromatic eyes mark me as a rare true mate. But I’m no wolf. I’m just Elle, a nobody from the human district, now trapped in Brad's world.
Brad’s cold gaze pins me: “You carry my blood. You’re mine.”
There is no other choice for me but to chose this cage. My body also betrays me, craving the beast who ruined me.
