Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.

I’m a proud NEET who’s devoured every romance novel, manga, webtoon, and otome game out there.Just when I thought I’d conquered it all, a black bunny appeared in my dream.“Congrats! You’ve been chosen to help villains win across multiple worlds!”“Like a game?”“Uh . . . sure.”“Great, I’m in!”And just like that, I became an agent of the Villain System.Time to rewrite some happily-ever-afters—villain style.**[NOTE!]** This novel features multiple short arcs, each exploring different tropes such as ancient China, the modern world, beasts, werewolves, vampires, fantasy, school romance, idol groups—you name it! The twist? Each arc focuses on our MC making the villain (male) triumph over the male and female leads.The story is written primarily in 2nd and 3rd person POV for a dynamic and immersive experience.|| Excerpt ||[WARNING! MATURE Content Ahead!]“Then serve me . . . properly.”The command was both sensual and authoritative, and Xue Li’s pulse quickened under his intense gaze. The air between them grew heavy, her trembling hands faltering as she began to run the sponge across his chest, her touch featherlight against his scars.“Y-yes your majesty.”Xue Li’s hand trembled slightly as she dipped the towel into the warm, fragrant water, her breath catching as she squeezed it out over Han Feng’s shoulders.The water cascaded down his chiseled frame, tracing every ridge and contour of his muscles. She swallowed hard, focusing intently on her task, though her heart raced like a drum in her chest.She began at his shoulders, her touch gentle as the towel glided over his skin. His scars, a mix of old battles and untold stories, caught her attention, and she hesitated for a brief moment before continuing.The warmth of the water mixed with the heat radiating from his body, and the intimacy of the moment sent a shiver up her spine.Han Feng leaned back slightly, watching her through half-lidded eyes, his expression unreadable. “Slower,” he murmured, his voice a low rumble that made her pulse skip.Xue Li obeyed, her movements becoming more deliberate as she ran the sponge across his chest, down the defined lines of his abdomen. Each stroke felt unbearably sensual, her fingers brushing his skin as she worked.She tried to maintain her composure, but the proximity to him, the sheer physicality of his presence, made her feel as though the air had thickened.When she reached his arms, he extended one lazily, letting her clean him as though it were his divine right. Her hand moved carefully, trailing down his forearm to his wrist, her touch so soft it almost tickled.Han Feng’s silence was oppressive yet charged, the pressure of his gaze pinning her in place.As she lowered the sponge to his torso again, her hand faltered briefly near the sharp line of his hipbone. The water ran over his skin like liquid fire, and her breath hitched when she noticed the slight curve of his lips, a hint of satisfaction playing there.“You’re trembling,” he said, his voice velvet smooth, making her flinch.“I-It’s the steam, Your Majesty,” she stammered, though she knew it was a poor excuse.Han Feng chuckled softly, the sound deep and rich. “Hmm . . . Is that so? Then you have no problem cleaning my cock right?”Xue Li's eyes trembled, on the verge of tears, which seemed to please Han Feng. His smile grew wider as he urged her on.“Go on. You're going to serve me properly, aren't you?”

“What does it feel like to be a shadow?”People say it's bondage — the absence of light, of freedom. But what is freedom, really?The ability to choose whatever you want?Or... just a beautiful illusion masking the void?Strange question, I know.But you'll understand soon enough.Because my lives?They've always been a little... enlightening.— Kaiser

“A qualified gunner should have enough firepower coverage.”

“So my battery has a diameter of three thousand meters, which is very reasonable.”

After a grand fireworks, Chen Jiang looked at the shocked eyes of the passers-by around him and said seriously.

When all races were thrown into a world and started to fight, a world with the theme of survival began.
