However, Zhuangzi next door suddenly came to the young lady of the high official’s family in the city.

This young lady is a direct descendant, but her mother passed away early, her father continued, and the young lady was not welcomed, so she was sent out of the city.

“There is an ominous foreboding!”

Yuan Bao thought so.

“Little sister, you see how pitiful the little sister is, can’t you be a little sympathetic?”

A brother looked at the lady next door with pity on his face.

Yuanbao raised his hand and a pot lid flew over: “People are pitiful? They don’t have to worry about food and clothing, do they need you to be pitiful?”

“Good fight!”

Grandfather, grandmother, father, mother, many brothers, clapped their hands together.

A certain young lady is knowledgeable and reasonable, and said, “Being habitual is like killing a child. Your sister needs to be well educated!”

“roll!”

A brother stared directly, “My little sister is beautiful and kind, which one likes her?”
