Zhai Yaohui treated Qiao Nan as part of the Zhai family.
They were one family. Qiao Nan had to help out when the Zhai family was in need of help. Now that Qiao Nan was in trouble, the Zhai family could not sit by, doing anything, and allowed her to be bullied.
Zhai Yaohui sneered at the thought of the Feng family in the capital. It seemed that as the Zhai family seldom visited the capital, many of them had forgotten that the Zhai family was like a tiger with sharp claws.
They thought that since the Zhai family was not in the capital, they could go overboard and create havoc under the Zhai family's nose. All of them had to pay for their recklessness and ignorance.
Now that the Feng family had provoked the Zhai family, there was no way that they could escape from the Zhai family's wrath. It was no use even if they got Shi Peng to mediate.
The Zhai family would do anything to protect their calf!
