- Description from Novelupdates

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?

Su Mingyuan has become a villain in the world of urban novels. As long as he plays well according to the villain’s setting and completes the plot, he can get villain points, and he can return to earth if he saves enough 100,000.

Unexpectedly, Su Mingyuan, who had saved enough money, unfortunately, encountered a turbulent flow in time and space when he crossed back to Earth, and the time went back to his first day as a villain.

Everything has to start again.

“It’s merely a matter of starting over; the required villain value is less than half what it was the last time, and my acting abilities have improved significantly since the last time. I’m able to deliver stronger performances and am able to acquire a greater number of villain values more quickly…”

Su Mingyuan is optimistic and confident.

“Let see, I will do my best to taunt the male and female protagonists to hate me and then be punched in the face by them!”

“See if I don’t do my best to ridicule, make the male and female protagonists hate me, and then hit me crazily in the face and step on me.”

“When it comes to acting as a villain, I’m a professional!”

To begin, the first step is to attempt to harass the male protagonist’s sister, so that the two create an intense dislike for me.

Hey, what’s wrong with you heroine?

Not only do you not resist, why do you seem to… enjoy it?

Can you be serious!?

I’m a villain!

Wait… wait!

Why, apart from you, the way other female protagonists look at me seems to be wrong?

They came up one by one as if they were going to… eat me?
