Marietta-hime no Konrei - Chapter 30 Pouring Love?

What is the most important thing about rebirth before the apocalypse? Grain storage? No, it’s trying to find the most important person in the past life! Reject the so-called relatives who have evil intentions!

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?

He is high above, the mysterious and terrible King of the Wild. With one glance, he can see people’s romances. He hates women to the extreme, but at his first glance of her, he dotes on her and spoils her.
She is a humble transmigrator, a miracle doctor who doesn’t care for the many handsome men around her. She only wants to become strong, to be worthy of that god-like man. But when she’s finally sure of her feelings, she finds out she’s already been married for years…
……
When wronged：
She uses strength to hit the big handsome iceberg-like man in front of her eyes. “People say that I’m not good enough for you, but it is you who is an old cow eating tender grass!”
A man seizes the main point and laughs like an evildoer. “This husband has to eat the grass to confirm if it is tender or not!” He puts out the red candle……
……
The world says：
The barbarian king has no heart and has no passion.
A pregnant woman very miserably thinks,” If he has no passion, then who is responsible for this big belly?”

“Sanye, do you know that you are like a book. Every time I see you I want to … sleep.”

After some hesitation, Xin Ai finally decided to approach Jian Sanye, who was famous for his power. She tried hard to make him happy, justify thousands of ways, sacrifice self-esteem and dignity, with the main goal to find her missing sister.

Three months later, the man threw a check in front of her, “I’m tired.”

Xin Ai stood up with her innocent body without a single strand, smiled wryly and said, “Alright, I’ll go as far away from you as possible.”

When they met again, Xin Ai closed her eyes to Jian Sanye’s presence, it made the man angrily push her against the wall, “We’ve slept together a few times. Is it so easy to forget me?”

Xin Ai smiled so sweetly and teasingly, putting her hand on the shoulder of the man, “Sorry, I have slept with quite a few men, sometimes I can’t remember it even happening. If I may know, what’s your name, sir?”

“Just watch, I’ll make you remember who I am.”
