My wife has a secret

After receiving the "blessing", Xu Qing became the eldest son of the Xu family in Suzhou. He was the only son in nine generations and the apple of the eye of the entire family.
He wanted to be a good person, but the original owner of this body was a notorious playboy, and the ladies and maids in the family did not believe him.
In this case, Xu Qing had no choice but to follow suit, hiding his cleverness in his clumsy ways, and making a splash once, twice, and again.
"What? Master Xu from the Xu Mansion has created another famous poem?"
"What? Master Xu actually invented a magical medicine that can replenish yang and strengthen the kidneys?"
"What? Mr. Xu's backyard caught fire?"
"..."
Xu Qing is very busy, but if the Queen Mother wants to see him for something, he still has to make some time.
