Contract Marriage: Abusive Love with Mr.CEO - Chapter 739 - 383: Extra: She Won’t Be Easily Defeated by Him (2)

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?

Soren transmigrated into Lover’s Labyrinth, a dating sim, not as a protagonist, but as a side character.That should have been fine. But instead, he awakened the Perverted Harem System, which gave shameless quests so absurd that even thinking about them made him seethe in anger.“This is a dating sim, not a pornhwa,” he roared in rage.From academy life to dungeon trials, his peaceful plan began to collapse as the system dragged him into chaos, embarrassment, and dangerously effective “accidental” progress.If he wanted to survive one event after another, he had to complete indecent missions without getting himself killed or exposed, all while simultaneously building a perverted harem of heroines far stronger than him.Surely… nothing could go wrong. Right?***
