Harry Potter: Eclipse. - Chapter 1:

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?

Lin Sui transmigrated into the cannon fodder of a cultivation text, a cannon fodder with a human cauldron constitution, destined to be a servant. Lin Sui, unwilling to resign himself to it, seduced the Son of Heaven, but when the cut out his Dao bone and transferred it to himself, the Heavenly Law struck him down.

That Dao bone in his body became the System that restrained him, issuing the order: You must retrieve all of his soul, serve him as your master in every world, and spare no effort for him until your dying day!

Lin Su was all smiles as he agreed, but all his life, the thing he loathed most was others telling him what to do.

Therefore…

In the first world, he was an arrogant and domineering, rich and powerful Young Master, while the other person was a pitiful and humble illegitimate child.

He humiliated him by saying he was only fit to carry his shoes, and spoke words of love next to his ear when the noise of the crowd boiled over.

System: You motherxxxxxx [beep——]

Lin Sui, innocently: Aren’t I serving him as my master?

In the second world, he was a newly-promoted top talent in the entertainment industry, while the other person was a former Best Actor who went silent after an accident.

He ridiculed and suppressed him, saying deserved to make a comeback even if he was past his prime, and kissed the scars on his body at night, leaving resources behind to gracefully leave afterwards.

System: [beep——]

Lin Sui, spreading his hands: Am I still not sparing enough effort?

In the third world, he was an S-rank Alpha, while the other person was a mentally-damaged former SSS-rank Alpha.

He looked down on him, saying that useless people also deserved to get back on the battlefield, and when no one was around he said ‘since you can’t smell pheromones, then I will be your omega’, and almost lost his life giving himself to the other person.

System: …..

Lin Sui, smiling: Is my dying day enough?

Even though, in the end, he was tucked away in a golden house by the wealthy upstart, captured by the triple gold Best Actor, and completely embraced by the Imperial Marshal, he was still happy.

System, weeping bitter tears: Big brother, I’m begging you, I won’t tell you what to do any more!
