MTL - Doctor Chen, Don’t Be a Coward! - Chapter 357 apprenticeship? !

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?

God answered the prayers of the human race and gave them a chance to fight back.He bestowed special marks called crests upon twelve who were worthy, granting them unfathomable power to fend off the wave of attacks.Well… that's what the church wants us to think.Man, being man, found a way. And in the present day, large numbers of the population have crests, and those that don't are treated as second-rate.This was the case with Marcus, who spent most of his life doing odd jobs—until one of those jobs led to his demise.At the hands of whom??The son of a major crest-bearing house.Marcus is reincarnated into the body of his killer and soon finds that despite being from a major house, the boy did not have a crest.At least, not one that was bestowed upon him by God.
