Legend says, that there is a great demon, who is the human kind’s public enemy. He is the galaxy federations’ nightmare as he wanted to conquer the whole universe. On the first day, he completely took out the human fleet, plunging them into disorder. On the second day, he declared that he will wipe out the whole federation. On the third day, he declared——that the hero who shot him in their previous battle must marry him, or else, he will destroy everything.

The galaxy federation president and the council members had a long meeting after that. They decided to dispatch a soldier, Wu Xing Yun, and marries him off to the arrogant demon. Wu Xing Yun was once a hero who fought for the nebula, and henceforth, he was tasked—— for the sake human race and the universe’s peace, to eliminate mistresses, settle his matters with the mother-in-law, and fix the man’s crooked ways.

Wu Xing Yun was very perplexed when he asked his commanding officer: “Sir, why did it have to be this way?”

Commanding Officer: “Soldier, bear in mind, that this mission of yours, is for the sake of the universe and mankind’s happiness. You must hold on to your husband, and fight other mistresses! Do you have the confidence to accomplish this task?”

Wu Xing Yun, stood straight, saluted, and instinctively replied: “Sir, yes sir! I will accomplish this task!”

“You are not afraid someone else might see you holding that?” he chuckled, amused that she even tried to lie. He can see through her excuses.

She dropped the book on a nearby table and started walking towards the door. “Fine, I won’t take it then,” she was all red as she conceded.

“I’m not saying you can’t learn,” he followed her. “You just need the right companion for it,” he said seriously.

She blushed, not able to tell if he is just teasing her or if he is serious about it. She made the mistake of looking back.

She was shocked at how close they are, she took a step back and find herself trapped behind the door and this giant of a knight.

“Then, I should ask around for someone to teach me in that department,” she said, trying to keep a straight face.

His eyes darkened, his bright gold eyes turning into dangerous murky gold. He placed his palm against the door, completely trapping her as he grinned.

“Do you wish to try that then, with someone, my queen?” if only she wasn’t clueless, she should have seen he wasn’t kidding.

.....

“Of course, I told you I am naturally curious. As a matter of fact, I’ll try that with someone as soon as we returned,” she continued with her lies and was interrupted only when he lunged forward and claimed her lips.

His hands were on her cheeks as he kissed her most passionately. Opening her lips to his tongue as he slides his tongue inside her mouth, tasting her and making her moan.

She felt scandalized by the sound she made so she tried to push him away. But he didn’t let her go, he grind his hips against hers rubbing his clothed cock with her still clothed but wet entrance.

Her skirt was lifted high as he made a thrusting motion, his hips gyrating with hers as their lower bodies rubbed together. The friction of the clothes they were still wearing brought her back as she said, “Don’t.”

He stopped when he heard her, then fixed her skirt and her hair, sniffing on her neck as he whispered, “If you really want to learn, I’ll be your partner, my queen. You need to learn from the best.”

She blushed and hurriedly opened the door running out of the castle and into the carriage. A smile formed on his lips as he looked at her panicked form climbing aboard her seat.

From a media tycoon’s daughter to a poor plumber’s girl, but it seems that Yu Yao is unfazed? She opened the eyes of the sky, and her life has been opened all the way. She is an eighteen-year-old girl, but as soon as she turns around, she becomes a big boss who no one in the entertainment industry dares to offend.
