“My wife, something is wrong!”

Not only is there something wrong with the lady, even the two little maids beside the lady and the rest of the Qin family are all wrong!

The big maid is sweet, charming and seductive, with a voice like a lark;

The little maid was as cold as ice and snow with a murderous aura, her throat was sealed as soon as she drew her sword.

My sister-in-law is talented, and she is as delicate and beautiful as Lin Daiyu.

The little cousin is arrogant and domineering, and the whip is fatal.

The father-in-law has a serious face, but secretly speaks dirty words.

The mother-in-law is as beautiful as a flower, and she loves to roll her eyes at the top of her head.

The second elder brother devoted himself to practicing martial arts and said that he wanted to honor his ancestors.

As for Luo Qingzhou, he just wanted to be a son-in-law honestly, and then sneak around and be invincible…
