Upon awakening, Lu Xuan found himself as an ordinary spirit plant cultivator, tending to an acre of land merely scraping by in the realm of cultivation.

Fortunately, he stumbled upon an unexpected revelation: with each maturing spiritual plant, he received additional rewards.

Harvesting a The Firefly Grass yielded a Golden Sword Technique.

From the Blood-Devouring Vine, he obtained a Purification Talisman.

And the Phantom Spring Flower gifted him a prescription for the elusive Luminous Flame Pill.

Henceforth, he contentedly tended to his own spiritual fields, observing the tumultuous tides and shifts in the world of cultivation.

“Duels and clashes, expeditions into secret realms, immortal fortunes, obtaining mystical treasures… None of it concerns me!”

“I simply wish for peace and quiet to tend to my fields.”

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?
