Divine Beast Ascension - Chapter 519

A lightning strike transmigrated Zu An into another world. In that world, he was known as the tr*sh of Brightmoon City, but for some reason, he was married to the gorgeous and highly talented daughter of the Chu clan?

How long I’d been here, I couldn’t quite recall. From this sorry situation, I as always raised my eyes to the sky; a sky in which the great, massive sun was clad in levity. Sunlight poured gently upon all. What a blessing it would have been for the world if only the skies could remain clear. For tomorrow too, and for all days to come, I was to continue to pray for calm. To endure for those who cried, with desperation I remained in prayer.

And then, one freezing, forlorn, soulless, stagnant, drizzly day we died. Or so I thought…

Luo Zheng is at the bottom of the Luo Clan hierarchy, despite his family being the founders of a power refining technique that could instantly defeat any opponent.

Fleeing his home and despicable clan, Luo Zheng must learn to harness his powers to rescue his younger sister while his own cousins are on his pursuit.

- Description from Novelupdates

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?
