You Were Supposed to Be the Dragon Son-in-Law, So Why Did You Become Emperor in the Enemy Kingdom?

Zhou Qing transmigrates and becomes the Fifth Prince of Great Qi.

With neither power nor influence, he lives carefree, listening to music in the pleasure quarters and playing the good-for-nothing to avoid the dangers of the struggle for the throne.

A love letter from a Great Qin princess leads the Third Prince to frame him for colluding with Great Qin.

Just as he is about to be thrown in prison, an envoy from Great Qin arrives to propose a marriage.

The envoy names Zhou Qing as Great Qin’s live-in son-in-law, threatening to crush Great Qi if they dare slight him.

In an instant, Zhou Qing goes from the most useless prince to an overbearing dragon son-in-law.

The Emperor of Great Qi also abruptly changes his attitude, taking an unusual interest in Zhou Qing.

Even the other princes admire him.

"Fifth Brother, I was wrong to suspect you. You’d marry that fat Great Qin princess for the sake of Great Qi. I’m not worthy to stand beside you!"

Zhou Qing is stunned. "What? The Great Qin princess weighs 300 jin?"
