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.

Xiao Chen was once a great soldier of Huaxia known for his strange, unique but effective tactics and plans during operations. He would always assume command and orchestrate highly-dangerous missions and would lead his unit to success.

He was known for being a great commander which made his military rank soar, from being a young lieutenant freshly graduate from the academy to becoming one of the youngest general that Huaxia had ever seen.

Sadly though his military career was cut short when he was deeply involved in the older generals politics. He died a tragic death when he was murdered by the men who he trusted so much and considered his brothers.

His soul wandered through the river of time and space still seeking vengeance and was soon swallowed up by a swirling light.

He soon found himself in the body of a monster or that’s what others consider him to be. He had a hulking figure pack with muscles,towering nearly 7ft tall, a pair thick tusks jutting out from his mouth and lupine ears along with the great desire for battle welling up inside him.

He begins his new journey as a green hulking monster or an orc as what his kind was called, a monster born for war and lived for war.

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?
