MTL - Battle Emperor - Chapter 23 evidence

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?

This story is centered around the man named Yi Ji-Hyuk, who has spent 1000 years in a Medieval Western fantasy-like world before returning back to the modern-day Earth. When he returns, he finds that his home is facing monster threats, and that humans with superpowers have appeared to protect the innocent people of Earth.

12 years ago, it was the beginning of his catastrophic life.

Just because of the Wang family’s selfishness in wanting to possess his family’s land, Baichen’s beloved parents were murdered in cold blood. And he himself was framed for a crime that jailed him for 200 years.

The fury building up inside him was enough for him to do anything to bring justice to himself and his family.

Finally, a chance to revenge came to him when he received the “Life Changing System” which allowed him to turn back time and fix everything before it happened.

He needed to complete various missions without knowing what he had to encounter in order to gain skills that helped him survive and revenge on the family who had destroyed his family and made him suffer!

“This time I won’t let anyone tear my family apart again. I’m going to kill Wang Chengye. I’m going to destroy the whole Wang family. My parents are going to live lives of happiness. I swear it!”
