Life Simulation: I Caused the Female Sword Immortal to Regret Forever - Chapter 11:

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!

The little cutie held him tight, not letting go. “”Handsome uncle, you look very much like the daddy I have lost for many years!”” Huo Yunshen felt depressed. “Me? Daddy?!”

The little cutie proudly pulled her mommy over, “”Mommy, I have found a long-term meal ticket for you, handsome and gullible.””

Xu Xiyan smiled at the elegant man.

Recalling the accident five years ago, his face sank. “”How dare you steal my DNA?””

She laughed. “”Not steal, just borrow!”” The man took her in his arms and warned in a dangerous tone, “”Woman, should I get what’s mine back, with interest?””

She stood on her toes. “”Yeah, how about another baby?”””
