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.

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?

…but it seems pretty doable.

Su Yan had been crushing on Wei Zhou for seven years, only becoming his wife after an accident. Everyone mocked her about her luck, claimed she had married above her station, ridiculed her, and ostracized her. But Su Yan didn’t care. Her seven-year crush had finally blossomed and she felt only bliss. Yet, Wei Zhou had thought she was a scheming woman who used underhanded tactics to win his hand. It was all a misunderstanding! Su Yan tried to explain but Wei Zhou wouldn’t believe her. Eventually, Su Yan stopped trying, believing that time would prove it all. One day, Wei Zhou was on the tabloids, rumored to be having an affair with a female celebrity. Su Yan sought an explanation from him. So long as he explained, she would believe him. But Wei Zhuo never explained. He merely answered coldly, “Just behave as Mrs. Wei and mind your own business.” Mind her own business? Su Yan laughed. Looking back, how much of a fool had she been to assume she could melt his iron heart? Any blazing passion would eventually die out from indifference until nothing was left. Su Yan then realized. She was rich, beautiful, and had a great body. Why must she waste her efforts on a heartless blockhead like Wei Zhou? Su Yan dragged Wei Zhou to the Civil Affairs Bureau to separate their union. From now on, whoever they dated had nothing to do with the other! After their divorce, Su Yan went back to being herself. Excellent as she already was, Su Yan unleashed her dazzling light upon the world once more. Then, once every few days, Wei Zhou would see gossip about his ex-wife on the trending searches. Yesterday, she was having a candlelight dinner with a movie star, today, she had brought home a young hunk to engage in passionate romance?! Wei Zhou threw his phone on the floor. “To hell with your passionate romance! That’s my woman!” Surrounded by gorgeous men and enjoying her life, Su Yan asked, “Mister, who are you?”
