The Little Prince in the Ossuary - Chapter 29

This is the tale of an earthling, who transmigrated as a dying third-rate god but somehow rose through the ranks, gaining followers and eventually causing the Fourth Great Apocalypse.

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?

Sure, the world is ruined, but I’ll live my own way. Of course, luxuriously and gorgeously.

I thought that when I was reborn, I would work hard to be strong—however, I only started to struggle when fate came.

Once, I was weak and powerless, but the ninja world imprisoned me bit by bit like a cage.

Hinata, Konoha, Ninja World, one day I will break the cage/break free from the shackles and act recklessly. And those who were about to die – will also be reborn.

Until leaving a sentence – tell them, this is the last time I will fight for this decaying village.

“What if you never come back?”

“Then they will never return.”

“It’s like the color of your eyes determines that we can never be together. Even at the last moment of my life, all I see is blood and night—and the only thing, the white of your eyes.”

“White—it’s so good!”

Is it really good – the world of white eyes is just pale without a trace of color.
