City of Sin (Yanyu Jiangnan) - Vol 1 Chapter 79: Invitation

Changqing has always felt that she’s incomparable to Guan Ying in every aspect. Even though she is pretty and has a good family background, this world is nothing more than a world where Princes are more attracted to Cinderellas.

In a future timeline, the earth was visited by a species known as the Slarkovs.
Having lost their home planet and in search of a new one, earth was the next habitable planet for them.

Humans and Slarkovs made a deal with each other in return for the Slarkovs living on earth.
The Slarkovs traded their technology and knowledge for a new home.
They were similar to humans except for some of them who had slight differences so fitting into the society wasn't a problem.
Over the years Slarkovs and humans began to mate with one another and reproduce offsprings.
This in turn created a new species known as the mixed-blood.
Centuries later mixedbloods could tap into their bloodline and perform unimaginable feats.

Gustav born into an age where bloodline determines everything, struggles to fit with a useless bloodline.
His bloodline only grants him the ability to change his hair color, destroying his hopes and dreams for a great future.
His fate is turned around when an unexpected situation leads to him finding a system that grants him the power to unlock and upgrade bloodlines by completing quests but he's baffled by two quests with a five-year deadline. Success will grant him unimaginable rewards...
But only one thing awaits him if he fails... Death!

Follow Gustav on his interesting journey filled with unprecedented adventures, danger and death, maybe?

In one moment, he was walking down the street with his little sister—In the next, he had traveled to the world of One Piece, carrying a system that could extract, record, and fuse genes to cultivate powerful lifeforms.Thus began a leisurely and carefree life in the most chaotic world imaginable.When bored, he’d snatch a bit of heavenly tribute meant for the Celestial Dragons.When curious, he’d raise a few cute kittens and bunnies just for fun.When restless, he’d wander through the territories of the most fearsome powers in the New World.Life is beautiful—so why bother taking anything seriously?

[MATURE CONTENT]Arella is an angel.Well, she used to be an angel. A real, bona fide, halo-wearing, wing-flapping celestial being. That was until one tiny whoopsie where she unfortunately burns a pair of wings at a banquet happens.Fine!There was more than one tiny whoopsie.Fast forward a few hours later, and Arella found herself booted from the pearly gates with nothing but her wings and an eviction notice.Her family called it a “vacation.” Ha! A vacation, in the human realm of all places!One hundred years later, Arella calls it her new life. Turns out, living among humans isn’t half bad—especially when you can turn invisibly smug at their lack of ability to fly. Early retirement has never been so blissful. That is, until the heavens smack her face with a message: Arella’s back on duty. And her new job? Marry. The. Demon. King.Wait, what?!Marrying the Demon King isn’t exactly on Arella’s bucket list, especially when demons and angels have been sworn enemies for eons. But orders are orders. So, off she goes, wings drooping and attitude cranked to full sass, to meet her new husband—a devilishly handsome demon who seems unnervingly smitten with her.Not to mention the heat that surges within her the moment she lays her eyes on him. Cue in dinner dates, fiery arguments (literally), and a series of catastrophes involving Arella purposefully setting a demon's hair ablaze with her holy fire.But as Arella settles into this bizarre celestial-demonic union, she uncovers a sinister plot that threatens not just her marriage but their entire reality. Turns out, angels and demons might have to join forces to stop a threat that neither side can handle alone. And Arella? She might just be the unexpected key to saving everyone.Armed with nothing but her quick wit, trusty angelic powers, and a painfully doting husband who may or may not leave her love notes carved into rock when she is angry, Arella must navigate battles, betrayals, and the occasional marital spat to protect their world. After all, nothing says “happily ever after” like saving existence itself, .... right?Right?One fallen angel. One absolutely smitten demon king. And a whole lot of chaos.
