Mysterious identity, three fathers to recognize, space in her left hand, a prince in her right.Building wealth, making big bucks, she never goes easy on the scum, and there's always someone to back her up in a fight.Xie Zhinuan thought, this life is just too sweet, it's not her fault she's so lucky.As for those losers, she really didn't want to fight them, but they asked for a beating by messing with her.All she wanted was to focus on her business, never thinking about marriage, especially not to someone so high-ranking and powerful... too scary, just too scary...Lately, what everyone was curious about was, “Did the Emperor succeed in his confession today?”

Everyone is not optimistic when the most renowned man in Yuncheng married the least favored miss of the Mu family.

Rumor has it that the young Miss Mu family is pathetic, weak and dainty and an easy subject to bullying.

Mu Huan nodded enthusiastically: En, I’m a bully.

The big man who was bullied by her didn’t know whether to laugh or cry: Doesn’t your conscience hurt whenever you claim this?

The once unloved Mu Huan, the moment she was a pampered wife, she became the mad devil . Since then, she was covered from fighting someone and taught when doing homework.

What evil step-mother, scum step-sister, black hearted white lotus, Mr. Bo will go all out to kill!

Being pampered and held in the palm of his hands, the conqueror of his heart, Mu Huan, was interviewed one day.

“Mrs. Bo, what is the secret to you and Mr. Bo’s everlasting love?”

“I like him the most, and he likes me best.”

Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?
