In a dilapidated temple, a young man receives an outdoor webcast system, and thus, his webcast journey begins. He easily finds lingzhi worth thousands of dollars, keeps a falcon as his pet, and displays skills that leave his audience in awe. When he turns his head around, he discovers that the whole world is watching him.

When he joins a show, everyone asks, “Is this webcaster cultivating to be a deity?”

Someone exclaims, “This isn’t an adventure, this is a vacation!”

A reporter asks him, “Your fans claim that you know martial arts. Is that true?”

He answers, “Not true.”

Yet, in the next moment, when a little red bird flies past him, he takes a leap from a tall platform before jumping down…

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?
