It does not satisfy the Kutta condition, Circulation Theory of Lift and Bernoulli's principle either? How can it fly? Is there a special power source in its body?” Richard could not help saying as he glances down at the huge dragon he was riding on. “Well, I need to research this.”“By the way, you said you kidnapped me to find a playmate for your daughter. That doesn't sound like a good reason, right?”“Roar!” the dragon hollers furiously and waves its wings, soaring into the sky.Will Richard be able to continue on his journey of exploration and unravel the mystery of the wizarding world?

She is a top-class spy, a poison specialist, but also a young and cute girl with a sinister temperament. In spite of her sweet and innocent appearance, she can complete any tasks without the slightest hesitation. One day because of an incomplete black magic, she was sent into the body of a girl who was deemed as a good-for-nothing. What kind of change will she bring to this continent?

A Prince said with bitter hatred, “I thought she was weak and easily bullied, therefore I broke off the engagement. I really didn’t expect she is such a shrewd girl. I made an error of judgment.”

The Crown Prince deeply sighed, “She is such a sexy evildoer! Obviously, she has a frail and tender body, but I am not able to overwhelm her…”

Finally, an Emperor hit the nail on the head, “She is just a bit two-faced!”

She answered, “You’re just a big pervert!”

The Emperor carried her into the room and said, “You are predestined to be mine! A two-faced girl and a pervert are a perfect match, right?!”
