Madam's IQ Is 68

A beauty with maxed-out combat skills, low intelligence, and a fake aloof act x a domineering CEO who only wants to marry a smart wife

Cen Lingzhao doesn’t want to be a domineering CEO. He just wants to open a traditional Chinese medicine clinic.

So he sets out to find a clever, capable partner for a marriage alliance.

At first glance, he settles on the eldest daughter of the Ai family, whom everyone considers clever and capable.

Ai Yunshu: My IQ is only 68? No problem, my little sister’s IQ is high! She taught me how to fool everyone! I love my sister! Long live my sister!

At first:

Cen Lingzhao: Heh, I married a top-notch career woman.

Ai Yunshu: Hehehe.

Later:

Cen Lingzhao: You tricked me into marriage! This is fraud!

Ai Yunshu: Now that I’ve been found out, I guess we’ll have to get divorced!

Cen Lingzhao: ...If you can fool everyone, doesn’t that count as being highly intelligent?

Note: The heroine is at the peak of physical strength; the hero has a soft, pampered vibe. Sweet romance at first, then a crime-and-police story later? Read with an open mind.
