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 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?

“The Fang family had two daughters. Their youngest daughter, Fang Yan, was known for her beauty. Rumor had it that she was indescribably beautiful. However, the eldest daughter of the Fang family, Fang Liu, had a low IQ since she was young and only started to speak when she was eight years old. Her parents regarded her as a burden while the outside world treated her as a laughing stock.

However, no one knew that Fang Liu was an ultimate prodigy whose intelligence merely developed late. Afterward, Fang Liu got pregnant for no reason. Four months into her pregnancy, her parents forced her to marry the richest man in South City, the Mo family. Rumors had it that her husband was an old man who had been paralyzed in bed since the age of seven. Unexpectedly, when Fang Liu married into the Mo family, she found out that not only was her husband not an old man, he was also extremely handsome.

He was the Young Master of the Mo family that everyone admired—Mo Yu! Moreover, Fang Liu’s child was not even Mo Yu’s, but Young Master Mo did not seem to mind? Mo Yu even declared in front of everyone, “”Although the child isn’t mine, the wife is mine!”” Everyone else, “”Young Master Mo is too honest!”” After Fang Liu got married, Young Master Mo doted on her so much that even she was moved. She had found a great stepfather for her child! A few months later, Fang Liu looked at her newborn’s face and it nearly felt like she was looking at a miniature version of Mo Yu. Fang Liu, “”Didn’t you claim that the child isn’t yours?”” Mo Yu shrugged. “”I was just spouting nonsense.”” It turned out that there was no such thing as the right person at the right time at the right place. It was all premeditated. “”It’s because I love you that I’ve tried everything I can; I endured all the criticism for my only wish is to have you as mine.

Before dying, the blind beauty Xiangnu accidentally entered an infinite escape world.
