Youkoso Jitsuryoku Shijou Shugi no Kyoushitsu e - Volume 16, Chapter 4: Dark Clouds, Part 1

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?

- Description from Qidian

Player: I’m a worker whose monthly salary doesn’t even hit $5,000. My monthly rental already takes up half of my salary, I don’t have a girlfriend and is reprimanded by my superior every day. However, I feel very happy because there has been a new virtual game recently. In the game, I have a powerful bloodline. Not only do I have my own fleet, I even have a powerful overlord that granted me a colonized planet. Although I know this is fake, but inside there, I found the meaning of my life!

Actually…the overlord who gave him the planet really wanted to tell him that this game wasn’t fake. (You really have your own fleet and colonized planet…) but the overlord knew that he couldn’t say this. Because, once he said it, these subjects who thought of themselves as ‘players’, would definitely not be as terrifyingly hardworking as now!!
